Description

The invention relates to an emergency call transmitter according to the preamble of claim 1.

Emergency call transmitters have been known for a long time and are sometimes used regularly by different groups of people. Users of these products are to a considerable extent falling and injury-endangered seniors, also younger needy people and persons, which are exposed due to the activity-related at work or leisure special dangers. The emergency call transmitters are used by the persons used for the purpose of manually triggering an alarm in the event of an unforeseen emergency and in this way being able to call for help. In addition to these emergency call stations, which are primarily triggered manually via an emergency call button, emergency call stations are also known which automatically trigger an emergency call, for example, in the case of a fall of the carrier. These automatically alarming emergency transmitters are not affected by this application.

However, an emergency call transmitter can only be meaningfully used for its function if, in an emergency, it can be quickly and easily reached by the person carrying the load for a manual emergency call release. Thus, these emergency callers are in an emergency in the accessibility of the needy people, such products are usually attached by means of a band or more bands on the body and primarily on the wrist, in the manner of a wristwatch worn.

The described emergency call transmitters have in common that they are composed of an emergency call triggering device, an electronic module, an enclosing housing for protecting the electronics and fastening means. Fasteners here are, for example, tapes with which the emergency callers are attached to the wrist of the wearer.

Especially for seniors and severely handicapped persons the wearing of an emergency call transmitter during the night's sleep is particularly important, since most emergency situations are caused by falls at night. These happen more often when those affected wake up at night and have to go to the bathroom quickly. Since eyes and circulation often do not adjust quickly enough to the sudden requirements, there are always falls on the way to the bathroom. In this case, sufferers often suffer such serious injuries that they can no longer move themselves. This is a big problem especially for people living alone, as their emergency situation is often only discovered hours or even days later.

The specified in claim 1 invention is based on the problem that emergency call handheld by your users are rarely worn at night. This is in addition to the sometimes inconvenient equipment housings often especially at the risk of accidental emergency call on the priority integrated mechanical emergency button. This can be unintentionally actuated by a body movement in bed. For many users, therefore, the emergency transmitter is at night next to the bed on a bedside table and is there from the bed easily accessible. However, this is no longer true after a fall on the way to the bathroom, since the emergency callers are usually not taken there. Thus, the desired by the emergency call transmitter security is no longer given.

The person skilled in the art knows from the state of the art, in addition to the usual market emergency call transmitters with an emergency call button, also emergency call transmitters with a train triggering device. Described is such a technical solution, for example in the application DE 31 03370 A1 , In this case, the user pulls on a mechanism in an emergency and thereby activates an emergency call. This technique results in a much lower susceptibility to false alarms when used during sleep, as the traction mechanism is normally not activated by body movement in the bed. In practice, however, these emergency call transmitters usually have larger dimensions and are worn mainly around the neck. However, this support is inconvenient during sleep, which prevents greater acceptance for use at night.

From the DE 10 2008 059 463 A1 An emergency call device is known which has been designed for false alarm suppression when worn during sleep. In this application, the components for the emergency call release are integrated in a flexible housing instead of a fixed housing. An emergency call is triggered by the gripping and squeezing of the emergency call bracelet and thus the gas enclosed in the hose. The pressure increase inside the hose caused by this is evaluated for the emergency call release. A disadvantage of this solution is that corresponding pressure changes inside the tube can also occur unintentionally during sleep and thus an absolutely safe suppression of a false alarm is not guaranteed. Furthermore, the same application also describes an emergency call triggering device in which several buttons of an emergency call band have to be actuated simultaneously or in a defined combination in order to activate an emergency call. A similar technical solution also describes the utility model DE 20 2007 002 573 U1 and the European application EP 1 816 618 A1 , A disadvantage of these statements is that the triggering of the emergency call for Most users are too complicated in stress situations and therefore often can not be triggered in an emergency emergency call. The EP 1 870 037 B1 describes a device for detecting falls with coupled automatic distress alert. The system evaluates the acceleration and rotation of parts of the human body caused by a fall and finally checks whether the body still moves after the suspected fall. A disadvantage of the device in the context of this application is that the described invention is used exclusively for automatic fall detection. An improvement of the false alarm suppression of manually triggered emergency calls by deliberately performed rotation of a mechanical subcomponent of the device is not provided.

The European application EP 1 249 808 A1 on the other hand describes the monitoring of the physical movement of persons. This is realized by means of a mechanical flywheel in connection with a micro generator for power generation. If there is no power supply to the energy storage connected to the micro generator in a defined period of time, the monitored person no longer moves. This leads to an automatic emergency call release. A disadvantage of this protection device in the sense of this application is that an emergency call release takes place here automatically in the absence of activity of the person wearing. An improvement of the false alarm suppression of manually triggered emergency calls by a deliberate rotation of a mechanical sub-component of the protective device is not provided. Furthermore, no special detection of a rotational movement takes place here. Rather, any movements are evaluated equivalently. Technologically, the motion detection is solved differently.

In the published patent application DE 31 03 370 A1 a portable emergency call transmitter is described, which is designed primarily for carrying around the neck. In the event of an emergency call, it is covered with one hand in an emergency and pulled down. The carrying method around the neck creates a tensile force, which finally actuates a switching element for emergency call release. Furthermore, an optional release via a device button is possible. Disadvantages of this invention are the inconvenient carrying method and the accidental position of the emergency call transmitter during sleep, as well as a technologically related increased susceptibility to false alarms during rotations in bed.

The invention of the international application WO 2004/019297 A1 describes a device for finding and protecting people, which also includes technical means for locating the persons who use this device z. B. wear in the form of a wristwatch on the body. So that the device can not be removed from the body unauthorized, this has a closure monitoring. If this is opened, an alarm signal is automatically issued. A disadvantage of this device is that it does not include any technical improvement of the false alarm suppression of deliberately manually operated emergency calls by persons.

In the European application EP 0 875 875 A2 we describe a method and a device for alerting auxiliary or monitoring bodies. In the emergency call case, the location coordinates of the triggering person are additionally transmitted in the form of GPS data to the receiving station.

A disadvantage of this invention is that it does not include any technical improvement suggestions for false alarm suppression of deliberately manually made by hand emergency calls by persons.

An emergency alarm via a wristwatch or a bracelet will be in the world registration WO 2009/109642 A1 described. To alert a touch sensitive area of the housing is touched or actuated a corresponding pressure-sensitive area. In addition, the emergency call device includes a sensor for automatic fall detection, or a detection whether a person is motionless. The emergency call device also has a pressure-sensitive area for canceling already-triggered emergency calls. A disadvantage of this invention is that the pressure-based emergency call triggering includes a high susceptibility to false alarms. Similar to standard emergency call handsets with key release is not guaranteed here that z. B. during the night silence false alarms, by unintentional pressure on the designated areas of the emergency call device, triggered.

The European patent application EP 1 160 812 A2 describes a mechanically rotatable emergency call switch for installation in motor vehicles. The emergency call switch is secured in its basic position by a mechanical spring lock against unintentional adjustment and thus against accidental emergency call. A disadvantage of the emergency call switch described in the context of this application is that it is not suitable for applications on the human body, since the trigger mechanism described in practice requires the installation of the switch in a rigid support plate. Furthermore, an emergency call is only triggered if two different movements are executed at the same time. In the mobile Personal emergency call, especially in senior emergency call, but simple procedures for emergency calls are required.

The US 4,981,453 A describes a distress buoy, which is used for automatic distress alert for capsizing or sinking ships. The invention has a rotatable magnetic mode switch in ring form. This switch can be used to select the different operating modes of the buoy on, off, set and test. The switching ring simultaneously visually displays the set mode to the operating personnel. A disadvantage of this invention in the context of this application is that the magnetic mode switch is not rotated in ring form for manual emergency call in an emergency situation, so as to improve the false alarm susceptibility of the triggering device against a key release. Rather, the rotation is generally outside a temporal emergency situation. Furthermore, the individual switch positions are protected by a mechanical lock against accidental adjustment. Before twisting the ring, they must first be unlocked.

The EPIRB RHOTHETA ^® RT-B77 offers three different activation options. Manual emergency call activation takes place via an integrated emergency call button, which must be pressed for at least one second to prevent false alarms. Furthermore, the device has a tear-off contact with tearing cord, which is pulled out of its rest position in an emergency. An emergency call is triggered as soon as the contact is out of its rest position for more than 3 seconds. The third activation option is an automatic alarm as soon as the emergency call transmitter is surrounded by water for more than 10 seconds. The device is switched on or off manually via a watertight rotary switch. A disadvantage of this invention in the sense of this application is that the false alarm suppression in manual alarm via a tear-off, which, however, can only be done once without subsequent service work. The integrated rotary switch is not used for manual emergency call by rotation.

The Breitling ^® pilot wristwatch has an integrated emergency call transmitter for the emergency call frequency 121.5 MHz. Through this transmitter, which is activated by unscrewing an antenna cap, followed by pulling out a wire antenna, the position of a needy wearer of the clock can be located in a large search area. The watch also has a bi-directional rotating bezel for static marking of a physical memory position. A disadvantage of the emergency watch in the sense of this invention is that the default emergency call can be performed only once without subsequent device service, since the antenna drawn for this purpose can not simply be pushed back into the housing afterwards. This is rather cut off to terminate an emergency call or wrapped around the watch case. The freely rotatable bezel, however, is not used by rotation for emergency call.

In the patent US Pat. No. 7,944,351 B1 a follow-up emergency call system is described. Radio telephone calls are first issued for possible regional receivers with low transmission power and short transmission times. If no acknowledgment of receipt, this emergency call is repeated with higher transmission power. Both transmission levels, as well as the active transmission times, can be increased several times in this way, while still missing acknowledgment. An emergency call release is also possible in the system by the coded turning of the bezel of a wristwatch, in the manner of a combination lock. Not described is the technical realization of this method.

The WO 2010/135518 A1 describes a vital monitor worn on the body, which in addition to different vital data additionally detects the movement data of the monitored person via three acceleration sensors positioned along the arm. The system alerts by radio to the exceeding of defined limit values as soon as either the vital data or the movement data indicate an emergency situation of the patient, wherein prior to the alarm reduction via algorithmic rules, with the help of the movement data, movement-dependent abnormalities in the vital data are evaluated. These rules are also based on determining the draw angle between the upper arm and the forearm. We do not describe the measurement of a rotation angle change of the measuring device relative to the body part which carries the measuring device.

From the registration WO 2010/030869 A2 is a mobile emergency call tripping unit known which avoids unwanted false alarms by the specification of mechanical procedures for emergency call. As an example, an emergency call activation by multiple rotary movements is mentioned here. It is not described how these rotary movements are evaluated technically for emergency call release.

The patent application US 2009/0322540 A1 describes an autonomous monitoring system for the fall detection of persons. This distinguishes between soft and hard falls based on measurable body movements and body turns during the fall. For measuring the relevant for the fall evaluation acceleration parameters are used in addition to an air pressure sensor for altitude measurement, preferably positioned on a wrist acceleration sensors. The sensors also evaluate rotational movements of the measuring unit worn on the wrist. However, a relative change in the angle of rotation between the measuring system with the acceleration sensor and the supporting wrist is not measured and evaluated.

Against this background, the object of the present invention is to provide an improved emergency call transmitter which offers an easy-to-handle emergency call triggering capability and at the same time reliably prevents undesired false alarms, for example while being carried during sleep.

This object is achieved by an emergency transmitter with electronic emergency call triggering device having the features of claim 1.

Advantageous developments are the subject of dependent claims.

The invention provides an emergency call transmitter with at least one electronic emergency call triggering device and a sensor system for detecting a rotational movement about an axis of rotation. The electronic emergency call triggering device is electrically connected to at least one electronic module for further data processing. The electronic components of the emergency call transmitter are at least partially disposed in or on a mechanical support unit, which is rotatable about a rotation axis in free space. By means of at least one rotational movement of the carrier unit, within the limits of the parameters predetermined for an active emergency call triggering, an emergency call is triggered. Under an electronic module are within the meaning of the invention arranged on a support components to understand that are required for the function of a mobile emergency station. In particular, such components energy storage, a control device and transmitting and receiving devices, such as antennas and high-frequency components. Depending on the functional design of the electronic module obviously other components can be provided.

The electronic emergency call triggering device and the sensors for detecting rotational movements about an axis of rotation are mentioned separately because of their particular importance in the context of this invention, but they are also primarily arranged on an electronic module.

The advantage achieved by the invention according to claim 1 is, above all, that the electronic emergency call triggering device of the emergency call transmitter is not accidentally triggered, for example during sleep by a rotation of the person wearing the bed. Instead, it reacts exclusively to a previously defined rotation of the carrier unit of the emergency call transmitter about an axis of rotation.

The desired quality of the false alarm suppression of the emergency call transmitter is defined here by the required relative rotational angle difference, which is to be exceeded by the rotational movement of the carrier unit, from the starting position of the currently detected rotational movement to the triggering of an emergency call. In practice, this rotational angle difference can be defined with any positive or negative angle greater than zero degrees. Obviously, this also includes larger angles than 360 degrees, which then add up from at least one complete revolution of the carrier unit and any addition-added angle. In a practical application, the evaluation of a rotary movement to trigger an emergency call, after exceeding a defined time interruption of the rotary motion, restarted.

Another advantage of the emergency station according to the invention is the versatile usability of the carrier unit for several functions. This results in low production costs for the product.

Thus, the support unit serves at least partially for receiving the electronic components or a housing in which they are housed. Furthermore, the carrier unit is used as a mechanical emergency call triggering component, which is rotated about an axis of rotation to activate a manual emergency call by the wearer himself or by another person present, for example by hand. In individual embodiments, it additionally serves to attach the emergency call transmitter to the body of the wearer. For example, when the carrier unit to be rotated is carried around a body part, such as the wrist. In particular embodiments, the carrier unit can additionally be provided with at least one band, a chain, a cord, a ring or a corresponding other holding device for fastening to the human body.

The carrier unit is primarily worn on the wrist. However, all further parts of the body are suitable for carrying, which allow a rotation of the support unit about the respective supporting body part or a rotational movement of the support unit on the body of the wearer. The carrier unit can in this case be made of any material which permits their production technically and which can be worn on the human body without negative health effects.

An additional advantage of the invention is the realizability of the emergency call transmitter in a reduced compared to the conventional hand transmitters size, since on large mechanical Components such as push buttons or a mechanical pulling device can be dispensed with. By eliminating the need for a mechanical release component and a simple installation in elastic housings is possible. Furthermore, this makes it possible to implement entirely electronic housings, for example printed circuit board protective coatings. The achievable reduction in height, while also possible elastic execution of the emergency call transmitter, increases the comfort of the emergency call transmitter, especially at night. Unwanted body pressure points are thus prevented.

According to a preferred embodiment variant of the invention, the carrier unit of the emergency call transmitter is mechanically constructed such that it can be rotated directly around the human body part which carries the unit. The triggering of a desired emergency call is carried out here by a hand or finger-induced rotation of the carrier unit, including the electronic triggering device and the electronic module arranged therein, around the human body part, which is used to carry this unit. Obviously, practicable use of the carrier unit as an easy-to-handle rotary triggering component for emergency calls, with reliable false alarm suppression by the electronic emergency call triggering device, can only be achieved if the carrier unit is adapted in size and mechanical design for the particular body part over which the carrier unit is carried , If the carrier unit is designed, for example, as a wrist sweatband, then it should primarily rotate only when it is manually rotated with the other hand around the wrist. If a carrier unit with a too large diameter is chosen, an undesired rotation of the carrier unit around the wrist is possible by a simple movement of the arm in the bed, for example by brushing against a ceiling. If, on the other hand, the diameter of the sweatband is too small, the sweatband brakes the rotation to be performed manually, resulting in a more difficult emergency call release.

In an advantageous embodiment, the sensory determination of the rotation of the carrier unit required for an emergency call triggering takes place around a human body part in the room, via at least one inertial sensor system, primarily MEMS acceleration sensor system. This sensor system, which is preferably arranged in the carrier unit, detects the spatial acceleration in an orthogonal coordinate system in three dimensions. Obviously, the sensor system can consist both of a component for determining all three axis accelerations or alternatively of at least two components for determining one-dimensional or two-dimensional accelerations. Furthermore, a combined use of physically similar sensors such as position sensors, tilt sensors, gyro gyros or any combination of these sensor types is also possible. Obviously, alternative sensor technology can be used for this purpose, by means of which a rotational movement about an arbitrary rotational axis in free space can be reliably evaluated. Based on a comparison of the measured motion data of the sensors in the carrier unit with the limits of this predetermined parameters is carried out by the electronic emergency call triggering an assessment of the movement, which either leads to an emergency call or suppresses such.

In a further advantageous embodiment, the carrier unit is rotatably mounted on at least one additional bearing unit. This bearing unit is disposed primarily between the supporting body part and the rotatable support unit and fixed to the body part. By means of at least one rotational movement of the carrier unit on the bearing unit, within the limits of the permitted parameters, an emergency call is triggered by the emergency call transmitter. Due to the mounting, rotational movements of the carrier unit are possible without the bearing unit being simultaneously rotated accordingly. In principle, a rotational movement of the carrier unit in any spatial plane to the position of the supporting body part is possible by the additional storage unit. For example, an application is practicable in which an emergency call is triggered by the rotation of a ring located outside the sight glass of a wristwatch. Other applications can be realized, for example, worn jewelry by rotating rotatably mounted components for emergency call. In this embodiment variant, the at least partial arrangement of the electronics and sensors required for the emergency call transmitter in the storage unit is advantageous.

Made possible by the rotatably mounted arrangement of the carrier unit on the bearing unit, the detection of a rotational movement of the carrier unit via at least one magnetic switching contact and at least one permanent magnet. The magnetic switching contact is actuated as soon as, due to a rotational movement of at least one of these two components, the distance between them becomes sufficiently small for sufficient magnetic influence. With optimum dimensioning of the two components, the magnetic switching contact is activated only when the distance between the two components is the smallest. A foreign influence by external magnetic fields is prevented by the required rotation for emergency call release multiple contact operations in a row, alternatively defined Time intervals are required. This is achieved by using a plurality of magnets on the rotatable carrier unit, within the magnetic coupling region to the at least one magnetic switching contact or by the arrangement of a plurality of magnetic switching contacts in the magnetic coupling region to the least one permanent magnet. Likewise, this effect is achieved by a multiple magnetic coupling of the same components together, for example by multiple 360 degrees rotations. Obviously, a combination of at least two of the measures described leads to the same result. In practice, magnetic switching contacts are often designed as reed contacts.

A great advantage of the development of the invention is the cost-effective production of the equipped with at least one magnet carrier unit, without required active electronic components. Furthermore, this is a simple waterproof execution of the storage unit, for example, a wristwatch housing with integrated emergency transmitter, produced. In an alternative embodiment, the at least one magnet is arranged in the non-rotatable bearing unit, in turn, the electronics of the emergency call transmitter with the magnetic switching contact in or on the rotatable support unit is applied.

In an advantageous development of the emergency call transmitter, its false alarm suppression is improved by virtue of the fact that only a defined angular difference, starting from the start position of a new rotary movement of the carrier unit, leads within specified limits to an emergency call release. If the generated rotation angle change is too small or too large, the triggering of an emergency call by the electronic emergency call release device is prevented.

In a further embodiment variant of the emergency call transmitter, its false alarm suppression is improved in that a rotational movement of the carrier unit, only in a defined direction of rotation, with respect to its spatial orientation on the supporting body part, leads to an emergency call release of the emergency call transmitter. If, for example, an integrated in a wrist sweatband emergency call transmitter is worn over the right wrist and rotated this carrier unit with the left hand, then with appropriate parameter setting a forward rotation, this show the fingers of the rotating hand in the direction of rotation, lead to an emergency call, while at a Reverse rotation with the same relative angle change an emergency call is suppressed. If parameterization is opposite, a reverse rotation will result in an active emergency call.

In an advantageous development of the invention, the false alarm suppression is improved in that a rotational movement of the carrier unit leads to an emergency call release of the emergency call transmitter, provided that the predetermined parameters for triggering, within their defined limits, are achieved within a predetermined period of time. For example, an application is conceivable in which a 90 degree relative angle change of the carrier unit over an interval of 1-3 seconds from the beginning of the current rotation results in an active emergency call release. If the rotational movement is too slow or too fast until the predetermined angular difference is exceeded, the emergency call release is suppressed by the electronic emergency call triggering device.

In a further advantageous embodiment of the emergency call transmitter, its false alarm suppression is improved by triggering an emergency call only if at least one change in direction takes place between at least two rotations of the carrier unit within a defined period of time and, in addition, the defined limit values of the parameters of each separate individual rotary movement are maintained. Thus, in an exemplary application, a 90 degree right turn of the carrier unit performed by the wearer followed by a 90 degree left turn could result in an emergency call release if the direction of rotation changes in a 1-3 second period. Obviously, it is still possible that only several changes of direction one after the other, each with its own angle changes in separately defined time periods, lead to an emergency call release. As a result, an arbitrarily complex coding of an emergency call release, similar to a rotary combination of a safe lock is possible, which leads to an extreme false alarm suppression, but increases the complexity of false alarm triggering to the same extent. Furthermore, thereby an active emergency call triggering is possible by not the carrier unit on a body part, but the supporting body part itself is rotated with the emergency call transmitter in one direction of rotation and then in the opposite direction of rotation. A practicable design is possible for this purpose, for example, with a wrist-worn distress transmitter. To trigger the emergency call, the person wearing it turns the wrist with the emergency transmitter, alternately to the left and to the right. Technically, the rotary sensor system responds to this as if the carrier unit is rotated back and forth on the body part.

In a further embodiment variant of the emergency call transmitter, an optimization of the false alarm suppression by the emergency call triggering device is achieved by an active emergency call triggering of the emergency call transmitter after a rotational movement of the carrier unit within the limits of the predetermined Parameter only takes place when the carrier unit is at the beginning of the rotational movement in a defined spatial position. Thus, in an exemplary application, the rotation of a carrier unit around the user's wrist would only result in an emergency call for the emergency caller if the arm with the carried or mounted carrier unit was held horizontal at the beginning of the rotational movement and exceeded a 90 degree relative rotation change by the rotation becomes. The same rotation angle change would result in a vertical arm attitude to no emergency call.

In an advantageous embodiment of the invention, a rotational movement of the carrier unit, within the predetermined limits of the rotational parameters, only leads to an emergency call, if the spatial rotation axis of this rotational movement changes only within defined limits from the beginning of the current rotary motion. Thus, for example, in such an application emergency call triggering of the emergency call transmitter by the electronic emergency call triggering device would be prevented if rotational movement of the carrier unit, within the limits of the predetermined parameters, occurs accidentally by turning the user in bed during sleep, as this clearly reflects the spatial axis of rotation changed.

In a further embodiment of the emergency call transmitter, an improvement of the false alarm suppression is achieved by a rotational movement of the carrier unit to the supporting body part, within the limits of the predetermined parameters, only leads to an emergency call of the emergency call transmitter, if the orbit generated by the rotary motion, the on or inertial sensors arranged in the carrier unit, run in defined track boundaries, the geometric data of the carrying body part and of the carrier unit being detected at least partially for calculating the limits of the permitted orbits for monitoring thereof. Thus, in an exemplary application, rotational movements of an arm on the wrist of which the carrier unit is worn, within the limits of the parameters set for deployment, do not result in an emergency call release, since the electronic triggering device causes the greater orbit thereby caused by the small orbit of rotational movement of the carrier unit differentiates around the wrist.

A reduction of unwanted false alarms of the emergency call transmitter is further achieved by a rotational movement of the carrier unit, within the limits of the predetermined parameters, only leads to an emergency call, if at least in a subsection of the rotation, the angular velocity within predetermined limits. Obviously, for further false alarm reduction, even complex angular velocity curves can be defined as a function of the angle change. Thus, in one example application, a steady acceleration of rotation while passing the required minimum relative angular difference could result in an emergency call release, while the same angle change at a steady rotation speed, within the same total time, would not result in an emergency call release.

In priority practicable embodiments, mechanical components are used or co-used as the carrier unit of the emergency call transmitter, which are often carried by persons on the body anyway. These are therefore not immediately recognizable by other persons as an emergency transmitter, which proves to be advantageous in various applications. Furthermore, this can often be dispensed with the wearing of a special mechanical component for the emergency call transmitter on the body. In customized versions, for example, textile sweatbands, watches, heart rate watches, bracelets, bracelets, arm cuffs, medical cuffs and jewelry are particularly suitable as a carrier unit in the context of this invention.

In a preferred embodiment variant, the emergency call transmitter changes in defined pauses without mechanical movement into an energy-saving mode with a significantly reduced range of functions. In this mode, emergency call is not possible. An energetic reactivation of the emergency call transmitter is effected by at least one movement of the carrier unit, for example caused by a movement of the supporting body part, which is detected by at least one inertial sensor or inertial switch, primarily positioned on the electronic module, and signaled by at least one status change to at least one electrical switch contact or output and evaluated. By a selective use of such inertial sensors with a preferred spatial triggering direction or a selektrische interconnection of at least two such components, there is a priority activation of the emergency call for desired movements, such as rotational movements. By activating the emergency call transmitter via movement, for example, the power consumption of a sleeping person can be significantly reduced. Furthermore, an increased power consumption takes place only when the distress transmitter is worn on the body. If it is stored, however, it is in the energy-saving mode for lack of movement. If, within a defined period of time, after the energetic activation of the emergency call transmitter, no evaluable rotation of the carrier unit takes place, the emergency call transmitter is put back into the power saving mode. A new intentional or unintentional Movement of the carrier unit activates the emergency transmitter again.

About the activation of the movement is the wearing of the emergency call transmitter on the human body recognizable. If no movement takes place in a definable period of time, the emergency transmitter can trigger an automatic message. Such a message can be sent, for example, to the user's phone to remind him to carry, but in principle a transmission to any other location is possible.

In a preferred embodiment of the invention, the emergency call transmitter for protection against mechanical influence and protection from dust, moisture or chemicals, at least partially integrated into at least one mechanically multi-sealable housing, which at least partially in the closure region of elastomeric material, such as silicone or the like Material is made. As a result of the shaping according to the invention, the at least two housing parts required for this purpose can be watertight, without the use of tools and external fastening means, repeatedly closed and opened again. This allows a low-cost execution of maintenance or repair work. For this multiple closure is on the closure surface of a housing part, for example, the housing cover, at least one mechanical bead, preferably applied completely and without interruption along the mechanical outer limits of moisture protected housing interior.

On the opposite closure surface of the second housing part, for example, the housing shell, is at least one circumferential opening, for example in the form of a groove, precisely matching the mechanical progressions of the at least one bead of the first housing part. This is narrower than the mechanical width of the bead. Spatially behind this circumferential opening is a mechanically connected directly to this, but preferably wider, cavity. In practice, the cross section of this cavity is mechanically adapted to the cross section of the bead. Obviously, the at least one bead in an alternative embodiment can also be integrated on the housing shell and the at least one groove in the housing cover. When using more than one bead for a closure, they can be arbitrarily divided on the housing parts to be closed together. Furthermore, more than two to be closed housing parts to protect the electronics used. For closing the associated housing parts, the peripheral, broader bead of the first housing part is pressed through the narrower, circumferential opening in the circumferential cavity of the associated second housing part. This is possible by making either the bead or the associated narrower groove, or both, of a stretchable restoring material. Due to the at least proportionate use of an elastic material for this closure, when the two housing parts are compressed, the wider bead can push through the narrower groove into the final closure position in the adapted cavity. For this purpose, either the bead must narrow sufficiently during passage or widen the opening of the groove sufficiently. Obviously, it is also possible that both the bead and the opening deform sufficiently at the same time. By a wedge-like basic shape of the bead whose entry is facilitated by the groove in the cavity, as a result of this wedge forces occur outward towards the groove. In practice, a combination of harder bead and softer groove is advantageous for easy sealing. After the bead has reached the closure provided for the correct closure, it is filled so that the surfaces of the bead and the cavity touch each other over a large area. With optimum mechanical dimensioning, either the bead or the cavity or both closure components are mechanically compressed after connecting the two housing parts. However, an elastomeric material would like to permanently return to the larger original shape in this state. As a result, a permanent, full-surface pressure is generated on the common sealing surface, which thereby prevents the penetration of moisture into the housing. In order to open the two closed housing parts, the bead is again pulled outward through the constriction of the groove by pulling force, contrary to the closing direction. For simplified opening of the assembled housing parts, these are provided in a preferred embodiment with mechanical handle options, such as retaining tabs. In practice, it has proven useful to form the housing and the closure in such a way that it meets the requirements of protection class IP 67.

A development of the invention provides that the at least one electronic triggering device or the at least one electronic module is formed on a carrier material by means of chip-on-the-carrier technology, preferably on a flexible carrier material. Obviously, both the electronic trip device and the electronic module can be manufactured using this technology.

The chip-on-the-carrier technology allows a housing-free design of the electronics used or parts thereof. Mechanical protection is usually effected by an applied protective layer. To save space can In addition, a three-dimensional chip-on-the-carrier technology can be used. In principle, however, can also be a conventional assembly with superficially applied components, a so-called SMD assembly, carried the carrier materials. If a rigid carrier material is used, this may be formed by conventional circuit boards.

In an advantageous embodiment of the invention, the emergency call transmitter on a thermovoltaic power generation device. This can be formed, for example, using thermocouples or Peltier elements. In this way, a temperature difference, which occurs as a result of the heating of the emergency call transmitter by the body heat of the user, are used to obtain the necessary for the operation of the emergency call transmitter electrical energy. As a result, an autonomous emergency call transmitter can be formed in which a change of energy stores or uncomfortable charging processes can largely be dispensed with. In an alternative or supplementary embodiment variant, an energy generating device is provided, by means of which acting on the emergency call transmitter or the carrier unit mechanical forces can be converted into electrical energy. In such generating devices, at least components of the emergency call transmitter are moved and thereby accelerated by the movement of the user. Thus, mechanical forces act on the emergency call transmitter. These can be made usable for example by means of a flywheel and thereby energy can be generated. This energy can then be converted into electrical energy.

An advantageous embodiment of the invention provides a radio frequency identification (RFID) transponder unit. This is preferably arranged on an electronic module. Such an RFID transponder unit can be used for the storage, processing and output of data or for position location.

In another embodiment variant, a position determining device is provided, which is preferably arranged on an electronic module. This may, for example, be a position-determining device which uses a positioning system based on a satellite, for example the Global Positioning System (GPS) or the European Galileo system.

A particular embodiment variant of the invention provides a means of induction rechargeable energy storage. In this way, in mobile operation, the number of required maintenance interventions for the emergency station can be reduced. An energy storage device which can be charged by means of induction can be formed, for example, from conventional accumulators and suitable coils. Also storage capacitors can be used as energy storage. The energy storage device which can be charged by means of induction is preferably arranged on an electronic module, it being possible to distribute individual components of the energy storage device which can be charged by means of induction, for example coils and accumulators, as required to different electronic modules. In addition, a state of charge monitoring for the energy store has proved to be advantageous in practice.

A further development of the invention provides a sensor device for recording vital data of the user. This is preferably arranged at least partially on an electronic module. Vital data are physiological data of the user, for example his or her body temperature, pulse or skin moisture. These vital data can either be evaluated in the emergency call device or sent to suitable recipients for evaluation.

The deposition of emergency messages and status messages by the emergency call transmitter takes place primarily via assigned frequency bands for alarm messages or emergency call messages to an assigned stationary radio receiver. There is either a local signaling or the radio receiver is connected to a higher-level signaling device, which forwards the emergency call, for example via the telephone network or data networks, such as LAN, to a desired emergency call receiver. Furthermore, these messages are also via paging systems, such as e-city call, set off or the transmission takes place via a regionally limited or private paging system, such as a pager call system.

A particular embodiment of the invention provides that the emergency call transmitter forwards its emergency messages and status messages via a short-range radio network, such as Bluetooth, low power Bluetooth or WLAN, directly to a mobile phone in its immediate vicinity. There is a direct signaling or visualization possible. However, priority is given to automatic forwarding via an available mobile radio network, such as GSM, to an external alerting destination, for example an alarm center. The mobile phone forwards the message either unchanged to this alerting destination or it supplements the message data with further meaningful data, such as the geographical position of the mobile phone, which is determined, for example, via GPS. The options described for setting the emergency call and status messages are obviously combinable.

In a further developed embodiment variant, at least one rotational movement of the carrier unit about an axis of rotation can be learned by the emergency call transmitter, this being compared with any later rotational movement of the carrier unit, taking into account defined tolerance limits, and an emergency call being triggered within the given tolerance limits if these rotational movements coincide. By learning the desired mechanical processes for alarm triggering an optimal adaptation of the emergency call triggering device to the needs of its users is guaranteed. An additional selection of the rotational parameters to be stored for the reference takes place in that they can be activated or deactivated individually for each reference rotational movement.

A local acoustic signaling of an emergency call is guaranteed. This can alert the person in need of help from the immediate vicinity.

In the following the invention will be explained in more detail with reference to figures. Where appropriate, elements having the same effect here are given the same reference numbers. Show it:

The second electronic module 31 On the other hand, it is constructed on a flexible carrier material and thus has a higher flexibility. This is the second electronic module 31 better in flexible Can be used areas of the carrier unit. The first electronic module 9 includes in addition to the electronic emergency call release device 7 especially the inertial sensors 11 , In an alternative application according to the 6 - 7 (not in 4 visible) would be the inertial sensor 11 by at least one magnetic switching contact 19 and at least one permanent magnet 21 replaced. On the second electronic module 31 is an induction coil 43 arranged, via which by means of a suitably designed charging device of the accumulator 45 can be charged without requiring an electrically conductive connection between the charger and the accumulator 45 needs to be made.

Furthermore, the accumulator 45 also via a harvester unit 33 loaded. In this case, electrical energy is generated, for example, by temperature differences between different points of the emergency call transmitter or by mechanical force acting on the emergency call transmitter. Via a transmitting device 41 Alarms or status messages are wirelessly deductible. The radio communication can be done either to an associated receiver as a point-to-point emergency call or via a wireless network, such as Bluetooth. Likewise, a transmission can take place simultaneously or with a time delay on different radio networks. Obviously, however, several transmitting devices can also be used 41 be provided to settle the alarms. The first electronic module 9 also has a sensor device 39 for vital data, by means of which, for example, physiological data of the user, such as body temperature, skin moisture, pulse or other can be detected.
