Example A of electronic lock

Electronic lock 100 will now be described with reference to the drawings, and in particular with reference to FIG. Electronic lock 100 includes a housing 102 having a first surface 104 that defines a major surface that facilitates interaction with electronic lock 100. Housing 102 is shown in a generally "box" shaped form factor solely for convenience of explanation and discussion of important features herein. In fact, housing 102 can take any shape and/or size to suit, for example, the intended use, the technology involved, aesthetics, combinations thereof, and the like. Electronic lock 100 may also be incorporated into a structure (eg, a diary, bag, luggage, wallet, or other item).

In practical applications, one or more features of electronic lock 100 may be exposed to a user through housing 102. For example, as shown in the example electronic lock 100 of FIG. 1, a lock opening 106 extends through a first surface 104 of the housing 102. Lock opening 106 defines an opening in electronic lock 100 that receives a corresponding locking mechanism. The locking mechanism may be integral to the housing 102 (eg, a shackle) or separate (eg, a removable component such as a zipper clasp). In practical applications, the particular placement, size, shape, etc. of locking aperture 106 will depend on the physical locking technique being implemented. For example, lock opening 106 may include or be configured to receive a clasp, shackle, hook, bolt, etc. (not shown in FIG. 1 for clarity).

An optional keyhole 108 may also be provided as shown. If utilized, keyhole 108 extends through housing 102. In the embodiment shown in FIG. 1, keyhole 108 extends through first side 104 of housing 102. In the embodiment shown in FIG. However, in other embodiments, the keyhole 108, if provided, may extend through or otherwise be coupled to any other surface of the housing 102. . Regardless of its location, keyhole 108 provides an interface to accept a physical key specifically configured to unlock/open the locking mechanism of electronic lock 100. As described in more detail herein, the physical key operates the locking mechanism independently of the electronic unlock signal (also described in more detail herein). Similarly, electronic locking mechanisms can unlock the lock independently of a physical key. As a result, in some embodiments, electronic lock 100 can always be opened, even if there is no power available to electronic lock 100.

Additionally, at least one electronic authorization device is provided. An electronic authorization device is used to authorize a user to a controller of an electronic lock. As described in more detail herein, authorization devices may include any number of modalities, which may include biometric scanners, electronic keypads, wireless communication devices, and the like. Examples of electronic authorization devices are described in more detail herein.

However, by way of example, FIG. 1 shows an authorization device implemented as a biometric interface 110 attached to or otherwise extending through the housing 102. In the embodiment shown in FIG. 1, biometric interface 110 is attached to or otherwise extends through first side 104 of housing 102. In the embodiment shown in FIG. However, in other embodiments, biometric interface 110 may be attached to or otherwise extend through any other surface of housing 102. Regardless of location, biometric interface 110 receives biometric information from the user. In some embodiments, the received biometric information may be used to unlock electronic lock 100. In other embodiments, the received biometric information may be used to lock the electronic lock 100. In further embodiments, the received biometric information may be used as part of multi-part authentication, verification, other schemes, etc. Examples thereof are described in more detail herein.

In practical applications, biometric interface 110 may form part of a fingerprint/thumbprint scanner. In this regard, biometric interface 110 may optionally include pad 112. Pad 112 provides an interface for receiving biometric input from a user. However, other biometric-based sensing techniques may also/alternatively be utilized.

Optionally, the electronic lock may also include one or more user interface input/output features. Input/output portion 114 may include buttons, pads, knobs, encoders, switches, or other input and/or output devices that facilitate user interaction with the lock.
Electronic lock example B

Referring to FIG. 2, a block diagram depicts one embodiment of the electronic lock 100 of FIG. In particular, a controller 202 is provided that handles the main processing of the electronic lock. In this regard, controller 202 may function as a "supervisor" processor that oversees the processing of other technologies, controller 202 may handle core processing itself or a combination thereof.

In particular, in the illustrated embodiment, an electronic authorization device implemented as a biometric reader 204 is electrically coupled to controller 202 . More particularly, the electrical coupling provides an electrical pathway for controller 202 and biometric reader 204 to communicate. In practical applications, electrical coupling provides a communicative coupling that may be unidirectional or bidirectional. That is, in some embodiments, biometric reader 204 transmits information to controller 202. In other embodiments, the communication is bidirectional, with the controller 202 sending information (e.g., commands, data, combinations thereof, etc.) to the biometric reader 204, and the controller 202 sending information (e.g., commands, data, requests, etc.).

Biometric reader 204 is also electrically coupled to biometric interface 110 (FIG. 1). That is, biometric reader 204 further interacts with corresponding biometric interface 110 and optional pad 112 of FIG. 1 to obtain electronic data corresponding to the biometrics read by the biometric reader. In this regard, the controller may compare biometric data accessible by the controller identifying the authorized user with electronic data corresponding to the biometric read by the biometric reader to authenticate the user. . In this regard, biometric reader 204 can be, for example, a biometric scanner for a fingerprint placed on pad 112 (FIG. 1), or biometric reader 204 can be any other biometric-based technology.

Some embodiments provide an optional electronic authorization device, such as, for example, an optional proximity-based wireless communication device 206 in addition to or in place of biometric reader 204. I can do it. A proximity-based wireless communication device 206 is also electrically coupled to controller 202. More particularly, the electrical coupling provides an electrical path through which controller 202 and proximity-based wireless communication device 206 communicate. In practical applications, electrical coupling provides a communicative coupling that may be unidirectional or bidirectional. Similar to above, in some embodiments, proximity-based wireless communication device 206 transmits information to controller 202. In other embodiments, the communication is bidirectional, with the controller 202 transmitting information (e.g., commands, data, combinations thereof, etc.) to the proximity-based wireless communication device 206, and the controller 202 transmitting information (e.g., commands, data, combinations thereof, etc.) to the proximity-based wireless communication device 206. Receives information (eg, commands, data, requests, etc.) from 206.

In practical applications, the proximity-based wireless communication device 206 may be implemented using any suitable short-range (e.g. , typically less than 30 meters) communication technology. As a further example, proximity-based wireless communication device 206 may include an active or passive radio frequency identification (RFID) device. Active RFID systems can provide a range of about 1 to 6 meters or more. Similarly, low power FOBs can be configured to be limited to a few meters. In other embodiments, the proximity-based wireless communication device 206 may include a near field communication (NCF) device (or other magnetic field induction technology that enables communication). In this embodiment, a working range of 10-20 centimeters is more practical. Additionally, proximity-based wireless communication device 206 can include inductive-based technology that requires close contact with the housing of electronic lock 200. In this regard, requiring contact with the housing of electronic lock 200 may be advantageous, for example, to increase the likelihood of intentional attempts to engage proximity-based wireless communication device 206.

Lock 208 is also electronically coupled to controller 202. Similar to above, the electronic coupling provides an electrical pathway for controller 202 and lock 208 to communicate. In this regard, communication may be unidirectional or bidirectional. Generally, lock 208 includes a combination of mechanical and electrical components necessary to mechanically implement the lock.

For example, lock 208 may include any electrical and/or mechanical components necessary to receive a locking mechanism (clasp, shackle, hook, bolt, etc.) through lock opening 106 (FIG. 1). may include or be coupled to. As an illustrative example, the lock 208 can be mounted on a solenoid, an electronic actuator such as an actuator (e.g., a linear actuator, a rotary actuator, etc.), a motor, a motor and cam arrangement, a motor and slider crank, or another device that converts rotational motion into linear motion. structure, etc. Components may also include electronic actuator control circuitry, if desired.

Additionally, additional mechanical components such as springs, wedges, locks, etc. may be provided if necessary to lock and unlock the device.

Generally, lock 208 moves from a locked position to an unlocked position in cooperation with a locking mechanism (eg, clasp lock, shackle, etc.) insertable into the lock opening. Therefore, the particular configuration of lock 208 will vary depending on the technology implemented, the type of locking mechanism used, etc. For example, a physical lock may have different components when securing a clasp attached to a zipper than when locking to the barb of a padlock or bar lock. good.

Although not required, in some embodiments, mechanical key receptacle 210 is configured to accept a physical key passed through keyhole 108 (FIG. 1), for example. Mechanical keypad 210 is configured to unlock lock 208 in a manner independent of the electronic lock circuitry so that the lock can be opened without the need for electrical power. That is, the lock is controlled to move from a locked position to an unlocked position by engagement of a physical key with a mechanical key receiver. Thus, the physical key can unlock the lock independently of the unlock command signal from the controller.

Providing a mechanical keypad 210 facilitates a backup mechanism for unlocking the device. Mechanical keypad 210 can also function as an electronic lock override, for example, in the event of an electrical or logical failure. Additionally, mechanical key receiver 210 can function as a Transportation Security Administration (TSA) key, making the electronic lock suitable for travel applications. Thus, the mechanical key receptacle can accept a physical key compatible with a Transportation Security Administration (TSA) key to transition the lock from a locked position to an unlocked position.

By way of non-limiting example only, the lock 208 may be connected to an electric actuator 212 controlled by a controller (e.g., a linear actuator, a rotary actuator, a motor, a motor and cam arrangement, a motor and slider crank, or a rotary motion to a linear motion). (e.g., other structures that convert to Electric actuator 212 provides an electronically controlled driving force to open the lock and transition the device from a locked state to an unlocked state. For example, electric actuator 212 can move a pin in response to an unlock signal from controller 202 to release a locking mechanism. In this example, a spring-loaded pin 214 may be used to hold the locking mechanism inserted therein. For example, a spring bias can be used to provide automatic and positive locking when a user inserts a locking mechanism through a locking opening in the housing. As some examples, inserting a clasp into a lock opening creates a bias against a spring that mechanically locks a pin into the clasp, so energy is expended by the electronics to reach the locked state. There isn't. A coupler 216 is provided to form a mechanical interface such that the controller 202 (e.g., via the electric actuator 212) or via a response by the mechanical key receiver 210 upon acceptance of a valid key. The pin can be actuated to unlock the locking mechanism (eg, the user inserts a valid physical key and rotates it appropriately). In this regard, the lock 208 includes both a mechanical release and an electrical release so that the mechanical release can override the electrical release or otherwise function independently of the electrical release. Optionally, other mechanical or electrical components 218 may be required to enable both locking and unlocking, such as one or more cams, gears, magnets, actuators, etc. .

Electronic lock 200 is also shown as having a power source 220. Power source 220 may include a battery that may be rechargeable, user replaceable, or otherwise configured. As used herein, "battery" includes batteries, cells, and other energy sources. The battery may be rechargeable, replaceable, or a combination thereof. For clarity, power supply 220 is not shown as being wired to other electronic circuitry, just for a clean schematic diagram. In fact, power supply 220 provides power to any component or components that require power. In this regard, the power supply 220 may include its own circuitry that is capable of entering a low-power sleep mode until a user initiates coordination with the electronic lock to unlock its locking mechanism. Includes sleep circuitry to minimize power consumption.

In example embodiments, the power source, controller, or other device may also regulate and/or monitor charging of the power source, as described in more detail herein. In this regard, a threshold (or thresholds) can be set that determines when the battery is likely to run out of charge. When the battery charge falls below that threshold, the lock may be unlocked so as not to leave the lock in the locked state. As an illustrative example, a measure of a battery characteristic (e.g., charge), as a percentage of expected charge remaining, may be measured at a predetermined threshold(s) (e.g., a first threshold and a second threshold). be evaluated against. A warning is provided if the charge is below the first threshold but above the second threshold. If the battery charge falls below a second threshold, actions can be taken, such as, for example, forwarding an email to the user's smartphone or automatically unlocking the lock.

As an illustrative working example, referring to FIGS. 1 and 2, generally, an electronic lock 100 may include a housing 102 with a lock opening 106 extending through a surface thereof. Lock opening 106 is configured to receive a locking mechanism, such as a clasp, shackle, etc., as described in more detail herein. Biometric interface 110 is attached to housing 102. Additionally, a locking system is included within housing 102. The lock system includes a controller 202. The lock system also includes a biometric reader 204 electrically coupled to the controller 202. Biometric reader 204 is also electrically coupled to biometric interface 110. When the lock is in the locked position and the locking mechanism is inserted into the lock opening, the lock transitions between the locked and unlocked positions such that the locking mechanism is locked to the housing. Correspondingly, the locking mechanism can be released from the housing when the lock is in the unlocked position.

Electric actuator 212 is electrically coupled to controller 202. Electric actuator 212 is operable to transition the lock between a locked position and an unlocked position. Battery 220 provides power to at least controller 202, biometric reader 204, and electric actuator 212. Here, the controller 202 includes electronic data corresponding to the biometrics read by the biometric reader and biometric data (one or more authorized users) that is accessible by the controller 202 and identifies the authorized user. Upon determining a match (such as a library containing electronic biometric signatures), an electronic unlock command signal is issued to the electric actuator 212 to move the lock from the locked position to the unlocked position. The controller 202 also sends an unlock command signal to the electric actuator that causes the lock to move from the locked position to the unlocked position when the measure of battery characteristics is below a predetermined threshold, regardless of the output of the biometric reader 204. Issued on 212.
unlock algorithm

Referring to FIG. 3, according to a flowchart, an example algorithm 300 is programmably implementable by controller 202 (FIG. 2), for example, to issue an unlock signal that electronically unlocks lock 208 (FIG. 2). It is shown. In this example embodiment, controller 202 requests multi-part confirmation that the individual has the proper permissions to unlock the electronic lock. In this illustrative example, two-part authentication is required, including authentication by a biometric scanner and input by a proximity-based communication device. In this regard, controller 202 may not care about the order in which it receives inputs. Accordingly, FIG. 3 illustrates receiving input from a biometric scanner and from a proximity-based communication device in parallel. This indicates that the user can enter biometrics first, interact with the proximity-based communication device first, or interact with both at the same time.

At 302, the algorithm receives input from a biometric scanner (eg, biometric reader 204 (FIG. 2)). In practical applications, the input is biometrics from a user wishing to unlock an electronic lock. Here, the biometric scanner compares the biometric received from the user to one or more predetermined biometric signatures authorized to unlock the lock. An example is when a user places a finger on a fingerprint pad. In response, the device reads the user's fingerprint. The scanned fingerprint is converted into electronic data. This electronic data is compared to electronic data, such as a fingerprint signature, which may be stored in a memory accessible to the controller, the biometric interface, or both.

At 304, the algorithm determines whether the biometric is a valid input. For example, a biometric scanner may attempt to match a user's biometrics to one or more stored biometric signatures. If the input is not valid, the process loops back to retrieve the input. Alternatively, if valid input is received, the controller considers whether valid input was also received from the proximity-based communication device. If no valid input is received from the proximity-based communication device ("match" at 306 is "no"), the process loops back again for user input.

Similarly, at 308, the algorithm receives input from a proximity-based communication device. As set forth in more detail herein, proximity-based communication devices may include near field communication devices, Bluetooth devices, RFID devices, FOBs, UWB, ZigBee, and the like. At 310, the input is checked for validity. If the proximity-based communication device does not authenticate valid input ("valid input" at 310 is "no"), flow returns to the beginning of receiving input.

Proximity-based communication devices can perform numerous authentication functions. For example, a proximity-based communication device may request or otherwise communicate with an associated pair of known devices. Here, a valid user must possess another device that is known and compatible with the proximity-based wireless communication device. As another example, a proximity-based communication device may require a passcode, key, pin, or other electronic input. These may be entered, for example, by a user interacting with the electronic lock itself (e.g., via input/output 114 (FIG. 1)) or via another device (not shown) in communication with a proximity-based communication device. or otherwise provided.

Alternatively, if valid input is received, the algorithm considers whether valid input was received from the biometric scanner. If no valid input is received from the biometric scanner ("match" at 306 is "no"), the process loops back again for user input.

If the user identification information is presented to both the biometric scanner at 302 and the proximity-based communication device at 308 (e.g., within a predetermined time of each other), the algorithm then selects a "match" box 310. In determining whether the biometric scanner and the proximity-based communication device identify the same user or whether the biometric scanner and the proximity-based communication device identify different users.

In some embodiments, matches must be from the same user. In other embodiments, the match requires that the users authenticating with the biometric reader and the users authenticating with the proximity-based communication device are different, but known and related people. In any case, if there is no match at 310 between the user identified at the biometric scanner and the user identified at 310 at the proximity-based communication device, then Then, the process loops back to the beginning to obtain one or more inputs.

Alternatively, if there is a match at 310 between the user identified at the biometric scanner and the user identified at the proximity-based communication device at 310 (e.g., within a predetermined time of each other), then , control proceeds to 312 where the controller issues an unlock command to, for example, lock 208 . Here, the predetermined time required for matching can be, for example, from a few seconds to a few minutes.

Accordingly, according to algorithm 300 of FIG. 3, upon determining a match of the multi-part electronic verification, the controller issues an unlock command signal to, for example, an electric actuator to transition the lock from the locked position to the unlocked position. . Here, the multipart verification is a match between a biometric read by a biometric scanner and an authorized user, an identifier read by a proximity-based wireless communication device, and a match between a biometric read by a biometric scanner and an authorized user accessible by the controller. (e.g., the same authorized user matched by a biometric reader).

In example embodiments, the proximity-based wireless communication device includes an NFC reader that communicates with a corresponding Near Field Communication (NFC) tag, and a Bluetooth receiver that is configured to pair only with authorized users. implemented by at least one of the following. Additionally, in these embodiments, the locking mechanism can include a zipper clasp. Here, the lock includes a locking member that prevents the clasp from being removed when inserted into the lock opening when the lock is in the locked position. As another example, the locking member may prevent removal of at least one of a shackle, hook, or bolt inserted into the lock opening when the lock is in the locked position.

In particular, even with multi-part authentication, in some embodiments, the lock can be removed from the locked position by the mechanical key receiver engaging the physical key, independent of an unlock command signal from the controller. It can be controlled to move to the unlocked position.

In practical applications, two independent verification mechanisms may be sufficient. However, it is possible to incorporate more and/or alternative verification mechanisms. In this regard, algorithm 300 may be modified to include additional, different, or fewer authentication mechanisms.

As a first example, if a proximity-based communication device is not provided, the system may authenticate based solely on input from a biometric scanner. Here, it is assumed that if the input at 304 is valid, then the match at 306 is satisfied.

Similarly, as a second example, if a biometric scanner is not provided, the system can authenticate based solely on input from a proximity-based communication device. Here, it is assumed that if the input is valid at 310, then the match at 306 is satisfied.

As yet another example, a system may include both a biometric scanner and one or more proximity-based communication devices, or a plurality of different proximity-based communication devices. Here, the controller may only consider valid input from one device, or may require verification from multiple devices, depending on the desired implementation, for example.

Accordingly, algorithm 300 can be modified to not require two-part authentication. Rather, match determination logic 306 may be optional. As a result of such modifications, the controller is independent of the mechanical key receptacle (if mechanical unlocking is provided) and is independent of the biometrics read by the biometric readers at 302, 304 and authorized. or a match between an identifier read by the proximity-based wireless communication device at 308, 310 and an authorized user; A lock release command signal is issued to cause the lock to move from the lock position to the lock release position.

As a further example, any of the embodiments described above can replace proximity-based communication devices and/or biometric reader scanners. For example, proximity-based communication devices and/or biometric scanners can be replaced with electronic lock user interfaces that require pin codes or other unique user input. As a further example, proximity-based communication devices and/or biometric scanners may be used, such as Bluetooth, UWB, ZigBee, Wi-Fi, GPS receivers, other global or local positioning systems, etc. can be replaced by another electronic component (or components). Additionally, multiple "authentication channels" (e.g., user I/O, Bluetooth, Wi-Fi, ZigBee, NCF, GPS, etc., any technology described herein for communication, user interaction, etc.) A match of n channels is required for the controller to issue an unlock command, where n is any integer greater than 0 (ie, 1 or more). Therefore, for example, there may be three or four authentication methods, and two or more of the authentication methods need to match in order for the controller to issue an unlock command.

Additionally, some secondary authentication can be automated. For example, if an authorized user places a fingerprint on a biometric scanner (e.g., a fingerprint reader), the controller may detect the geographic location by looking for a Bluetooth device, smartphone, etc. known to be associated with the user. by checking the user's identity, attempting to automatically obtain confirmation of the user's identity, attempting to read the NCF or other badge or tag associated with the user, etc. For example, in other embodiments where security is more of an issue, the user may, for example, physically touch the NCF device to the housing of the electronic lock, or send the NCF device to the user's smartphone via Wi-Fi or Bluetooth. respond to messages sent to you, require the user to enter a pin on an electronic lock housing, require the user to enter a pin on an associated smartphone, or send an email to a smartphone texting app. You may be asked to actively participate in double verification by responding to requests, app push requests, text requests, etc.

In some embodiments, if the controller detects a predetermined number of unauthorized identification attempts, the controller may issue a lockout and therefore, e.g. The owner may be required to reset the controller by requesting an administrator login. The user may be required to reset the lock using a physical key or the like.

In some embodiments, algorithm 300 can be modified to provide a number of additional features that can increase the flexibility of the lock. For example, there is no strict requirement that the user entering the biometrics be the same person providing the input via the proximity-based communication device. For example, there may be situations where it is desirable to require two individuals to unlock a lock. As yet another example, one individual may use a biometric scanner for multiple different inputs. For example, a user may be required to scan more than one finger, resulting in a different signature for each finger. Biometric scanners can be used in other ways. Examples thereof are described in more detail herein. Here, there may be a multi-part certificate for each user, or two or more individuals may split ownership of different components of the multi-part certificate.
Example C of electronic lock

Referring to FIG. 4, an example block diagram of an electronic lock 400 is shown. Electronic lock 400 is similar to electronic lock 200 of FIG. Accordingly, like elements are designated with like reference numbers 200 greater than the corresponding element. Therefore, a detailed description of similar components will not be described in detail here.

Additionally, electronic lock 400 can perform any of the processes herein, including the process described with reference to FIG.

However, FIG. 4 shows a memory that may store a user list 430, among other electronic data. Here, the memory, and thus the electronic user list, is communicatively coupled to controller 402. Controller 402 accesses data stored in user list 430 to determine, for example, whether valid input indicating an authorized user has been received from the biometric scanner (see 304 in FIG. 3). It may be determined whether valid input indicating a user is received from a proximity-based communication device (see 310 of FIG. 3), a combination thereof, and the like. As some illustrative examples, user list 430 can store biometric signatures, such as fingerprint signatures. Each fingerprint signature is associated with a unique authorized user. User list 430 may also store electronic identification data such as signatures, e.g., identifiers, PIN codes, electronic keys, electronic passwords, etc., associated with corresponding proximity-based communication devices. The ability to correlate and normalize different authentication techniques to a common user list allows multi-part authentication to be performed efficiently on the device itself.

In practical applications, there are several ways to program user list 430. The user list can be uploaded to the local database via a hardware connector such as USB (not shown for clarity). As another example, the user list may be uploaded wirelessly (e.g., using a smartphone, computer, etc., e.g., via a connection to a network such as Wi-Fi). Further, the controller 402 implements a secure management mode in which the controller 402 itself builds a list of valid users and associates each valid user with a unique biometric signature and with a unique input via a proximity-based communication device. The algorithm can be executed.
Example D of electronic lock

Referring to FIG. 5, an example block diagram of an electronic lock 500 is shown. Electronic lock 500 is similar to electronic lock 400 of FIG. 4 and/or electronic lock 200 of FIG. Accordingly, like elements are designated with like reference numerals 300 greater than corresponding elements in FIG. 2 and 100 greater than corresponding elements in FIG. 4. Therefore, a detailed description of similar components will not be described in detail here.

Similar to the block diagram of FIG. 4, electronic lock 500 includes a controller 502, a biometric reader 504, a proximity-based communication device 506, a lock 508, a power source 520, and a user list 530. These components may be similar to the dual of FIG. 4. Further, electronic lock 500 may perform any of the processes herein, including the process described with reference to FIG. 3.

However, a Bluetooth transceiver 532 is added in FIG. Bluetooth transceiver 532 can function in several capacities. A Bluetooth receiver can function as a short range transceiver for programming and communication. Alternatively, a Bluetooth transceiver can function in place of or in addition to proximity-based communication device 506 for multi-part authentication. For example, Bluetooth transceiver transactions may be replaced by proximity-based communication device transactions in the algorithm of FIG. Alternatively, the algorithm of FIG. Directional authentication can also be performed. Alternatively, a Bluetooth transceiver can function in place of a biometric scanner, proximity-based communication device, etc.
Example E of electronic lock

Referring to FIG. 6, an example block diagram of an electronic lock 600 is shown. Electronic lock 600 is similar to any combination of the disclosures of electronic lock 200 of FIG. 2, electronic lock 400 of FIG. 4, or electronic lock 500 of FIG. Accordingly, like elements are designated with like reference numerals 400 greater than corresponding elements in FIG. 2, 200 greater than corresponding elements in FIG. 4, and 100 greater than corresponding elements in FIG. Therefore, a detailed description of similar components will not be described in detail here.

Similar to other electronic locks described in more detail herein, electronic lock 600 includes a controller 602 (capable of executing algorithm 300 of FIG. 3) and a biometric reader 604. Electronic lock 600 also includes a lock 608, a power source 620, and a user list 630. Additionally, electronic lock 600 may perform any of the processes herein, including the process described with reference to FIG.

Electronic lock 600 may also include one or more communication devices, as shown in more detail herein. For convenience of illustration, these device(s) are shown at block 634. Here, the communication device(s) may include NCF, Bluetooth, UWB, ZigBee, Wi-Fi, combinations thereof, and the like.

Electronic lock 600 also includes a positioning system 636. Positioning system 636 may be implemented as a global positioning system (GPS), a local positioning system, or the like. Incorporating GPS allows electronic locks to implement geography-based decisions into the algorithm that determines whether to issue an unlock command to lock 608. For example, a geographic fence may be set up that requires the electronic lock 608 to be outside of a defined geographic area(s) for the algorithm to issue an unlock command. Similarly, positioning system 636 can be used to establish a geographic containment area within which electronic lock 600 must be within predefined geographic boundaries for the algorithm to issue an unlock command.

In particular, other metadata may be used in conjunction with or in place of geography-based data to enhance algorithm 300 for the algorithm to issue unlock commands. For example, an administrator may set electronic lock 600 to open only during set hours on set days, etc. Geographical and metadata requirements may be in addition to or part of the required n-part certification, which is described in more detail herein.

As some examples, an electronic lock may include a global positioning system (GPS) receiver controlled by a controller to determine the position of the electronic lock when an attempt is made to unlock the lock. In some embodiments, the controller reads the list of geographic boundaries and determines whether to request multi-part electronic verification. For example, if the user is in a geographically fenced area, such as a public place, multi-part verification may be required. As yet another example, multipart verification may be disabled if the user is in a geo-fenced area, such as a secure location.

As an illustrative example, the controller can be programmed with at least one approved geographic boundary. Here, when the controller determines from the GPS receiver that the electronic lock is within predetermined and approved geographic boundaries, the controller issues an unlock command signal to, for example, an electric actuator to trigger a fingerprint scanner. transitioning the lock from a locked position to an unlocked position from any one of the provided authorized devices, such as a wireless communication device or a proximity-based wireless communication device; The controller is configured to issue an unlock command signal to, e.g., an electric actuator, to transition the lock from a locked position to an unlocked position when the electronic lock is not within predetermined and approved geographic boundaries. Part electronic verification may be requested. In other embodiments, the two roles described above can be reversed. For example, if the controller determines from the GPS receiver that the electronic lock is not within predetermined and approved geographic boundaries, the controller may issue an unlock command signal to the electric actuator to transitioning the lock from the locked position to the unlocked position from any one of the authorized devices present; The controller is configured to issue an unlock command signal to, e.g., an electric actuator, to transition the lock from a locked position to an unlocked position when the electronic lock is within predetermined and approved geographic boundaries. Part electronic verification may be requested.

Electronic lock 600 is also shown as having a device port 638. Device ports 638 may include universal serial bus (USB) ports and the like. Device port 638 can function to recharge a battery (eg, power supply 620) that powers electronic lock 600. Device port 638 may also be used to provide power to electronic lock 600, such as when the useful life of the battery has expired. Additionally, device port 638 can be used to load data into user list 630, for example. Additionally, device port 638 may be used to extract information from electronic lock 600.

For example, electronic lock 600 can log authorization attempts, such as capturing data when the lock is accessed. Electronic locks can also use positioning systems to tag authorization attempts with geographic data, which creates a record that reflects not only that the lock was accessed, but by whom and where. can be created.

Electronic lock 600 may also include one or more input/output devices (I/O) devices 640. Examples of I/O devices include speakers, microphones, haptic devices, transducers, piezo elements, lights, LEDs, displays, and the like. In example embodiments, I/O device 640 is coupled to controller 602 such that controller 602 interacts with I/O device 640 and I/O device 640 coordinates with other features of electronic lock 600. Allowed to move.

By way of example, I/O device 640, implemented as a microphone and coupled with voice recognition software running on controller 602, enables voice activation of the unlock command. Here, a user can train controller 602 to cause the controller to unlock lock 608 in response to voice commands. Additionally (and/or alternatively), in some embodiments, voice commands may be used to cause the controller 602 to move the lock 608 to the locked position. Optionally, voice commands may also be utilized to turn certain features on or off. For example, a biometric scanner, Bluetooth, GPS, NFC, or other features provided for a particular device 600 may be enabled or disabled. Further, a pre-specified command can cause the controller to begin listening for voice commands. For example, a command such as "hey lock" may trigger the lock to begin listening for voice commands. In this regard, the controller can be programmed to listen to identify (eg, authenticate) characteristics of the audio signal based on linguistic characteristics. The controller can also be programmed to listen for particular words, sounds, or combinations thereof. Command words may be embedded within sentences, hiding the true trigger word. In this regard, the controller may make a recording over a time window and then parse the recorded speech looking for trigger words, sounds, etc.

As yet another example, I/O device 640 may be an LED and/or an LED and speaker/transducer. Here, the controller is programmed to respond to user requests to find a lock. Thus, an LED can be programmed to turn on, flash, change color, etc. to transmit a "beacon." I/O device 640 may also play sounds, such as chirps, alarms, etc., to assist in locating electronic lock 600.

As yet another example, a smartphone can connect to the lock via, for example, Bluetooth, Ultra Wideband, Wi-Fi, USB, or other wired or wireless technology. In this implementation, the lock includes a suitable transceiver, USB interface, etc. to communicate with the smartphone. Similar to the voice example above, the smartphone's microphone is coupled with voice recognition software running on the smartphone, for example via an app, to enable voice activation of the unlock command. Here, the user can train the app's voice software to cause the controller 602 to unlock the lock 608 in response to voice commands. Additionally (and/or alternatively), in some embodiments, voice commands may be used to cause the controller 602 to move the lock 608 to the locked position. Optionally, voice commands may also be utilized to turn certain features on or off. For example, a biometric scanner, Bluetooth, GPS, NFC, or other features provided for a particular device 600 may be enabled or disabled. Further, a pre-specified command can cause the controller to begin listening for voice commands. For example, a command such as "Hey, Lock" can trigger a smartphone app to start listening for voice commands. In this regard, the smartphone app can be programmed to listen to identify (eg, authenticate) characteristics of the audio signal based on linguistic characteristics. Smartphone apps can also be programmed to listen for specific words, sounds, or combinations thereof. Command words may be embedded within sentences, hiding the true trigger word. In this regard, smartphone apps can make recordings over a time window and then parse the recorded speech looking for trigger words, sounds, etc.

In further example embodiments, a smartphone may be used to power a controller (eg, controller 602) and/or other components of the lock. For example, a user may be required to enter a biometric signature. However, the smartphone app contains the same signature library (or a subset of the same signature library) as the lock. Thus, the smartphone app can read biometric signatures using the smartphone's biometric scanner in addition to, or instead of, the lock's biometric scanner. In another example, a smartphone can receive software updates, etc. using its transceiver (e.g., Wifi transceiver). Software updates and the like can then be loaded onto controller 602. In yet another example, the lock's controller can communicate with a smartphone app to perform enhanced functionality. For example, a lock may not include built-in GPS, but may rely on smartphone GPS and the smartphone's computing power to perform any of the geographic features described in more detail herein. perform one or more of the following: In this example, the lock can utilize a graphical user interface that includes a touch screen and the computer processing power of a smartphone to offload data-intensive processing. This saves energy, extends battery life, and requires less computing power in the lock. Here, if the lock receives input indicating that the controller needs to issue an unlock command, the lock's controller first communicates with the smartphone app to ensure that the unlock command does not meet the requirements of geographic boundaries, e.g. Checks whether it was received within the network, whether the required authentications were met, etc.

Additionally, in some embodiments, a user can set unique pairing requirements for the lock's controller to pair with a smartphone. This makes it possible to ensure secure and highly reliable pairing with the lock. As an example, when using Bluetooth, a user may set unique discovery parameters (eg, a passkey, PIN, passcode, password, or other security code). The lock's Bluetooth receiver requires this unique discovery parameter before pairing can be successfully completed. When a user attempts to pair with a lock, after discovering the lock, the lock requires the user to enter the correct discovery parameters. Discovery parameters are set by the user of the lock, so the user can pair any smartphone. Thus, for example, if the user's smartphone is not charged or in the user's possession and the user needs to unlock it using the smartphone, the user may borrow the smartphone from a trusted source. , you can pair a new smartphone, download all the necessary apps, and then use the app on the borrowed smartphone to have the controller issue commands to unlock the lock system.

Further aspects of the disclosure provide that the controller of the lock is integrated with the smartphone, e.g. to offload technology and/or software processing, thereby passing the same or similar functionality to other electronic peripherals/accessories. be able to. For example, in some embodiments, the lock can be controlled to issue an unlock command in response to commands received from the smartwatch.

In further embodiments, the smartphone functions as a graphical user interface to pass important information to the user. For example, a lock's controller can send messages (e.g. directly or via cloud infrastructure) to a smartphone app to provide information about battery level, access details, lock status (locked, unlocked, etc.). ) etc. As another example, a smartphone app can act as a "finder" by locating locks based on GPS, wireless communications, or a combination thereof, for example.

The smartphone app may also be programmed to perform certain locking or unlocking functions automatically or upon user interaction, for example, based on proximity to the lock. For example, in example embodiments, an alarm is triggered by the smartphone when the lock exceeds a predetermined range, distance, etc. from the smartphone app. As an example, the Received Signal Strength Indicator (RSSI) can be used as the estimated distance of the lock from the smartphone. In addition to alarms, the smartphone app can automatically send commands to cause the lock to lock itself (if the lock design allows for automation). Additionally, the smartphone features described herein may enhance, override, or be overridden by the lock's normal functionality. . For example, in some embodiments, the lock is typically automatically unlocked just before the battery is discharged and becomes too low to respond to commands. However, if the smartphone app detects that the lock is not within a predetermined range, this normal unlock sequence can be overridden so that the lock is not automatically unlocked. This smartphone override can be geographically bounded so that if the lock is within a defined geographical boundary, for example the user's home, the lock will simply unlock if the battery gets too low. can. On the other hand, when the lock is at another geographical boundary (e.g. a designated geographical location such as a public place) or when the lock is outside the designated "secure" geographical boundary, the smartphone and the lock to prevent the lock from automatically unlocking if the lock's battery becomes too low.

Various embodiments are shown to illustrate features of electronic locks. In fact, an electronic lock according to aspects herein may be generally implemented using any one or more features described with reference to any one or more of the present drawings. be able to. Accordingly, each of the present drawings illustrates a non-limiting example embodiment comprised of a number of components, processes, etc. that may be combined with features of components, processes, etc. from other embodiments herein. represents. For example, an authentication device such as a GPS device 636 may be implemented in the configurations of FIGS. 2, 4, 5, and the like.

As another illustration, an example embodiment of an electronic lock includes a housing having a first surface, a lock aperture extending through the first surface of the housing, a keyhole extending through the housing, and a biological lock attached to the housing. May include a metric interface. The housing includes, for example, a controller, a biometric reader electrically coupled to the controller, and a proximity-based wireless communication device electrically coupled to the controller. The lock also cooperates with a locking mechanism insertable into the lock opening to transition from the locked position to the unlocked position. For example, the lock may include a locking member that prevents removal of a zipper clasp inserted into the lock opening when the lock is in the locked position, and the locking member may include a locking member that prevents removal of a zipper clasp inserted into the lock opening when the lock is in the locked position. , at least one of the shackle, hook, or bolt inserted into the lock opening is prevented from being removed.

Furthermore, the mechanical key rest is configured to accept a physical key. In this arrangement, the controller matches the biometrics read by the biometric reader with electronic data identifying the authorized user, or a proximity-based wireless communication device (e.g., corresponding near-field electronic radio communication (NFC)). at least one selected from a match between an identifier read by an NFC reader in communication with the tag, a Bluetooth receiver configured to pair only with authorized users, and electronic data identifying the authorized user; Based on the electronic verification, an unlock command signal can be issued that moves the lock from the locked position to the unlocked position in a manner independent of the mechanical key receptacle. Additionally, the lock is controlled to transition from a locked position to an unlocked position by engagement of a mechanical key receiver with a physical key, independent of an unlock command signal from the controller. In some embodiments, a first proximity-based wireless communication device, such as an NFC reader, that communicates with a corresponding Near Field Communication (NFC) tag, and a second proximity-based wireless communication device, such as a Bluetooth receiver. Both may be present. As described in more detail herein, an electronic lock may be used, for example, to determine the position of the electronic lock when an attempt is made to unlock the lock, as described in more detail herein. , a positioning system that is a Global Positioning System (GPS) receiver controlled by a controller.

However, other combinations of the features described herein may be combined to form an electronic lock. As an example, the electronic lock includes the GPS 636 of FIG. 6 and the proximity-based wireless communication device 406 of FIG. 4, but the biometric reader may be omitted altogether.

With general reference to this figure, the example techniques described herein can be used in a variety of ways to cause a controller to issue an unlock command. For example, the controller may respond to a PIN (eg, a personal identification code) as a means of establishing authentication to issue the unlock command. A PIN may be a sequence, pattern, or other code that is entered into a smart device, such as a smartphone. If the smart device is running an app, the PIN may be used in addition to or in place of pressing an "unlock" virtual button on the smart device's graphical user interface. Here, the PIN may be any combination of alphanumeric or special characters.

The PIN may also/alternatively be implemented using coded pulses similar to Morse code, for example. Code entry can be implemented by tapping a biometric reader (eg, biometric reader 204). In this way, instead of reading actual biometric input, the biometric reader detects activation and sends a signal to the controller. The controller is programmed to "listen" for a series of pulses or activations and convert these received series of pulses or activations into a PIN. If the interpreted pattern matches a pre-stored pattern, the controller can send an unlock command. Thus, for example, determining a match between electronic data corresponding to a biometric read by a biometric reader and data identifying an authorized user collects a series of taps on the biometric reader. The method may include collecting data corresponding to the biometric read by the biometric reader, thus forming a PIN, and comparing the determined PIN with data identifying the authorized user. .

In view of the above, yet another example implementation of an electric lock includes a housing with a lock opening extending through a surface and a biometric interface attached to the housing. A locking system is also included within the housing. Here, the locking system includes a controller. The lock system also includes one or more authentication devices. For example, a lock system includes a biometric reader electrically coupled to a controller and to a biometric interface. When the lock is in the locked position and the locking mechanism is inserted into the lock opening, the locking mechanism is locked to the housing, and when the lock is in the unlocked position, the locking mechanism can be released from the housing. , the lock transitions between a locked position and an unlocked position. Correspondingly, an electric actuator is electrically coupled to the controller and is operable to transition the lock between a locked position and an unlocked position. In this configuration, the controller determines a match between the electronic data corresponding to the biometric read by the biometric reader and the data identifying the authorized user or the user is accessible by the controller. Upon detecting that the biometric interface taps a PIN that matches a PIN stored in some memory that corresponds to the user, it issues an electronic unlock command signal to, for example, an electric actuator to move the lock from the locked position. Move it to the unlocked position.

This same concept can be applied to other input devices. For example, instead of the controller using voice commands itself, the user can tap with a microphone to send a pattern of touches. The controller listens for a pattern of taps, and if the interpreted pattern matches a pre-stored pattern, the controller sends an unlock command to the lock. Instead of or in addition to tapping, the microphone can use speech, pitch, duration, volume, or a combination of these to match patterns to inputs that can be matched to pre-stored values representing authorization. Can be assembled and trigger an unlock command. Furthermore, the PIN code can be tapped into the graphical user interface of a smartphone linked to the lock, for example via Bluetooth, Wi-Fi, Ultra Wide Band, etc.

A related approach can be taken using location sensing features such as GPS. A user can program a geographic location as a locked or unlocked location. Additionally, other devices connected to the controller can be converted into PIN code generators using techniques similar to those described above. This allows the features provided by electronic locks to serve multiple purposes. This includes use as a PIN generator in addition to or in place of its use in the normal function of the associated device, as described in more detail herein.

Additionally, as set forth in more detail herein, users who own smart devices (e.g., smartphones, smart watches, smart fitness trackers, tablets, laptops, etc.) may, for example, Smart devices can be linked to electronic locks, such as via ultra-wideband. Using technology such as UWB allows the controller to be programmed with rules that affect whether the controller issues an unlock command. For example, Ultra Wide Band, Bluetooth, Wi-Fi, and similar technologies can sense the presence of an external device without actually communicatively pairing or connecting with the external device. As such, the controller may be programmed, e.g., via a user interface of a smart device (e.g., smart phone, smart watch, smart appliance, etc.) or computer (e.g., by using the techniques described in more detail herein). ) and the unlock command only if the user authenticates to the controller and one or more specific external devices (e.g., different from the user's smart device) are present or absent. can be issued. For example, if the controller detects that the user is at home, the home Wi-Fi router can broadcast the Wi-Fi network name that is recognized by the controller. The controller can use WiFi detection as a type of speculative positioning system to know that the user is in a familiar environment and therefore authorize the unlock command. Many other examples can be implemented based on the disclosure herein.

Users can also pair smart devices, such as smartphones, to the electronic lock. In this configuration, when GPS, Bluetooth, Ultra Wide Band, Wi-Fi, etc. are used with the electronic lock, the smartphone, or both, the controller determines whether the electronic lock is within the smartphone's predefined geographic boundaries. can be judged. In this regard, the controller is programmed with rules that prevent the controller from sending an unlock command to the electronic lock if the electronic lock is outside the defined geographic boundaries.

In yet another example embodiment, the controller is programmed to utilize signal strength, for example, by received signal strength indicator (RSSI) or other measures of power, signal strength, or other measurable parameters. .

The controller may also issue an unlock command based on predefined authentication, as described in more detail herein. In some embodiments, authentication can occur from one feature/modality (eg, biometric input, smart device pairing, PIN code entry, etc.). In other embodiments, the controller performs multi-technical/multi-modal verification (e.g., NFC and smart device pairing, or any two or more modalities/features described herein). , programmed with rules that provide predefined authentication. In a further embodiment, the controller is configured to provide a single feature/modality or multiple features/modalities with external environmental criteria, e.g. within geographic boundaries (e.g., in your own car, at home, etc.) and within the presence of external devices (and only in the absence of known external device presence, etc.) programmed with rules that define authentication based on

Additionally, if the controller has access to memory, the controller can store metrics including successful unlocks, failed attempts, timestamps, and other metadata. These metrics can be exported to the smartphone, either directly or via a cloud-based data collection process, for example.

In some embodiments, the controller may include a bootloader and other features that allow a smart device, computer, etc. to flash the electronic lock with a software update (e.g., to change firmware). .

Further, as best shown in FIG. 6, in some embodiments the controller 602 can communicate with a power source 620 (eg, with a power source sensor). Thus, for example, controller 602 can monitor battery characteristics such as battery charge. In this regard, when the battery falls below a certain charge (e.g., a first threshold, such as 10% battery remaining), the controller 602 sends a message to the user informing the user that the battery requires recharging, e.g. (such as a tone, light indicator, email, or text) to your smartphone. If the battery level is below a second threshold level (eg, 5%), controller 602 opens the lock in some embodiments. In this example, the measure of battery characteristics (e.g., charge) is measured as a percentage of the expected remaining charge, relative to predetermined threshold(s) (e.g., a first threshold and a second threshold). be evaluated. However, other suitable measures may also be implemented.

Here, the controller 602 fixes the lock in the locked state (or by controlling an LED (e.g., I/O 640) to blink or change color when a second threshold is exceeded indicating that the lock needs to be unlocked Be able to provide feedback. The percentages shown for the first and second thresholds are only examples. Other values can be used instead.

Referring generally to the present drawings, some additional non-limiting, but illustrative examples include receiving a clasp into a lock opening (e.g., lock opening 106, FIG. 1) to For example, it can be released by a spring-loaded release). As another illustrative example, the zipper and lock may include magnets that are attracted to the lock opening 106. In yet another example, a hook can be inserted into the lock opening 106 and rotated by the locking mechanism, thus releasing the zipper, hook, or other suitable structure from the lock opening 106. As yet another example, the snap can be connected to the lock either by a magnet or by a small hole in the snap. Here, the magnet is released when the magnetic attraction is overcome. A snap with a small hole can be connected to the lock. Here, the lock includes a rod that enters the lock opening 106 to secure the snap. The mechanism herein pulls the rod out of the snap upon receiving an unlock command, allowing the snap to be released. Therefore, the user always has the ability to snap. However, electronic locks can turn the locking mechanism on or off.
Example of zipper lock

Referring now to FIG. 7, an example electronic lock 700 is shown. Electronic lock 700 may actually include any combination of the features described herein. For clarity of discussion, the illustrated electronic lock 700 includes a housing 702 having a first surface 704 that defines a major surface that facilitates interaction with the electronic lock 700. Housing 702 is shown in a generally "box" shaped form factor solely for convenience of explanation and discussion of important features herein. In fact, housing 702 can take any shape and/or size to suit, for example, the intended use, the technology involved, aesthetics, combinations thereof, and the like.

In practical applications, one or more features of electronic lock 700 are exposed to the user through housing 702. For example, as shown in the example electronic lock 700 of FIG. 1, a lock opening 706 extends through a first surface 704 of the housing 702. Lock opening 706 defines an opening in electronic lock 700 that receives a corresponding locking member (shown in this example as zipper clasp 707).

Electronic lock 700 can include an optional keyhole 708 extending through housing 702. In the embodiment shown in FIG. 8, an optional keyhole 708 extends through the first side 704 of the housing 702. However, in other embodiments, the keyhole 708 extends through or otherwise couples to any other surface of the housing 702 (e.g., back, side, etc.). I can do it. Regardless of location, the keyhole 708, when utilized, provides an interface to accept a physical key specifically configured to unlock/open the locking mechanism of the electronic lock 700. As described in more detail herein, the physical key operates the locking mechanism independently of the electronic locking mechanism. Similarly, electronic locking mechanisms can unlock the lock independently of a physical key. As a result, electronic lock 700 can always be opened even if there is no power available to electronic lock 700. In some embodiments, keyhole 708 may be omitted.

Additionally, a biometric interface 710 is attached to or otherwise extends through the housing 702. In the embodiment shown in FIG. 7, biometric interface 710 is attached to or otherwise extends through first side 704 of housing 702. In the embodiment shown in FIG. However, in other embodiments, biometric interface 710 may be attached to or otherwise extend through any other surface of housing 702.

I can do it.

Referring to FIG. 8, a zipper clasp 800 is shown in a perspective view. For example, zipper clasp 800 can implement zipper clasp 707 in FIG. Zipper clasp 800 generally includes a zipper attachment 802 that attaches to a zipper of a corresponding article (eg, bag, wallet, backpack, carrying case, pouch, etc.). A zipper handle 804 is coupled to zipper attachment 802 for grasping by a user. A zipper lock arm 806 extends downwardly toward the distal end of the zipper handle. The zipper lock arm is generally orthogonal to the zipper handle 804. Zipper lock arm 806 includes an opening 808 that extends completely through the zipper lock arm. Additionally, a zipper lock arm surrounds the opening 808. In this manner, the locking mechanism of the electronic lock (eg, FIG. 7) cooperates with the opening 808 to lock the zipper clasp 800 to the electronic lock 700 when the electronic lock 700 is in the locked state.

9A and 9B, a locking system according to aspects of the disclosure herein is shown. The locking system can be implemented within the housing 702 (FIG. 7), for example. FIG. 9A shows the locking system in a locked state, and FIG. 9B shows the locking system in an unlocked state.

The locking system receives a locking mechanism 900 (eg, zipper clasp 800, FIG. 8). Additionally, the locking system includes a drive device 902, such as a motor, a locking lever 904, a spring-loaded unlocking mechanism 906, a lock defined by a locking pin 908, a locking spring 910, e.g., as described with respect to FIGS. or any combination thereof, an energy source, such as a battery 914, and a release spring 918.

9A and 9B, generally when the locking mechanism 900 (e.g., zipper clasp) is inserted into the locking system and the locking lever 904 is in the locked state (FIG. 9A), the user The locking arm (806, FIG. 8) biases the locking mechanism downwardly into the housing so as to compress the release spring 918. When the release spring 918 is compressed, the opening (opening 808, FIG. 8) aligns with the locking pin 908. The end of locking spring 910 biases locking pin 908 through opening 808 in zipper clasp 800 to lock zipper clasp 800 into the locking system. Here, the release spring 918 is maintained in a compressed state and is kept in a compressed state by the engagement of the locking pin 908 with the opening of the locking mechanism.

As best shown in FIG. 9B, to unlock the locking mechanism 900, the control circuit 912 causes the drive device 902 to rotate its shaft in response to an unlock command so that the cam causes the lock lever to rotate. 904 to slide laterally across the locking system. Here, drive device 902 and cam define an electric actuator, which is described in more detail herein. Lock lever 904 includes a wedge-shaped surface that engages a block of lock pin 908. As the cam moves the locking lever 904 laterally, the wedge of the locking lever 904 is biased against the block of the locking pin 908 such that the locking pin 908 disengages from the spring-loaded locking mechanism 906 and compresses the locking spring 910. Move. When locking lever 904 retracts locking pin 908 sufficiently to remove locking pin 908 from zipper clasp opening 808, the spring-loaded unlocking mechanism, under spring force, releases locking pin 908 from zipper clasp opening 808 via release spring 918. from the housing.

Referring to FIG. 10, selected components of the locking system are shown in more detail for clarity of discussion. The components shown in FIG. 10 can be utilized to implement the components of the locking system of FIG. Accordingly, similar components are designated with similar reference numerals 100 greater than their counterparts shown in FIGS. 9A and 9B.

During operation, when a user pushes the locking mechanism 1000 (eg, a clasp) into the housing of the lock, the protrusion of the clasp compresses the release 1016 via the spring 1018. To maintain release 1016 in a biased position, locking pin 1008 includes a tip that enters an opening in a protrusion of locking mechanism 1000. Lock pin 1008 is biased toward the opening by spring 1010. In this manner, spring 1010 and spring 1018 compress and expand in orthogonal directions. To unlock the device, a locking lever (see locking lever 904) moves laterally across locking pin 1008 in a cutting motion into the "C" opening. When the locking lever engages the locking pin 1008, the locking pin 1008 begins to retract, compressing the spring 1010 until the tip of the locking pin 1008 is released from the opening in the locking mechanism 1000. When the tip is released, the bias of spring 1018 forces release 1016 upwardly, ejecting locking mechanism 1000 from the housing of the lock. The release spring thus biases ejection or partial ejection of the locking member from the lock housing.
