Description

The present invention relates to a device with which fully automated emergency calls are deductible. Furthermore, an appropriate software or a suitable method is presented by the present invention, which can run on such emergency call devices such as an emergency indicator or can control such an emergency call device. In other words, the following invention deals with a device for transmitting an emergency call, a help request, a support or rescue request, and comparable messages according to the preamble of claim 1.

Technical area

Moving persons can face extraordinary events, such as As accidents, crashes or other mishaps, suspend. In addition, over and over again people suffer physical ailments that are not caused by external influences but have similar negative health effects, or suffer from chronic diseases such as diabetes. Frequently, the persons are only delayed, sometimes too late for life-sustaining measures or resuscitation, found. Even if many people electronic devices such. B. portable phones, lead to a contact with trained forces does not take place, at least not sufficiently in time, although a health-promoting measure could have been taken.

State of the art

From the DE 196 39 492 A1 (Applicant: Bernd Sendler, filing date: 26.09.1996), the proposal is known to develop an as comprehensive as possible device for persons in need of assistance with numerous different modules. The description mentions a wide variety of sensors and measuring devices. There are 16 different modules proposed, all of which can be monitored and polled by a connection and control system to initiate certain activities when system states that are defined as critical or dangerous are achieved. Such a device is extremely complex due to the large number of sensors. In addition, the number of sensors promotes the susceptibility to errors.

task

Ideal would be a device or module, the z. B. can also be used as a retrofit of equipped with an operating system phones, such as an Android phone that has simple but reliable processes and functions for implementation as an emergency call device.

invention description

The object of the invention is achieved by an emergency indicator according to claim 1. Advantageous developments can be found in the dependent claims.

The emergency indicator is intended to identify an emergency event and, after an identification, to transmit a help request, e.g. B. to a medical service, to a mountain rescue or other rescue services trigger. As a basis for the formation or creation of emergency indicators, a variety of electronic platforms can be used. In an advantageous embodiment, a, preferably equipped with an operating system such as an Android operating system, smart phone (GSM phone, LTE phone or similar, portable, in public networks einbindbare phones) is used. Equally advantageous independent, equipped with a minimum electronics electronics boards, preferably in impact-resistant housings, can be used. Additional benefits are gained when the housings are waterproof. If similar processor types are used, it is possible, at least in principle and advantageously also in structure, to use comparable, if not almost identical, software for the various electronic platforms. In this case, the different electronic platforms have in common that they are suitable for data transmission, either by voice data or by e-mail data, possibly even both, in particular using public telecommunications networks whose "last mile" are realized radio-based.

In order for the emergency indicator to be able to transmit the transmission of a request for assistance as self-sufficiently as possible, the emergency indicator should-according to a particularly favorable embodiment-comprise a separate electrical power supply. For increased compatibility, an electronic processor unit as a receiving module and processing module for a control program is advantageous. In addition, the emergency indicator may include a storage unit in which to store electronic data. The processor unit is in communication with the electronic storage unit. At least one transmitter unit is provided for the transmission of the help request. In addition, the emergency indicator includes at least two sensor devices, but more than two sensor devices may also be present. The first sensor device and the second sensor device are of different designs.

The processor unit is adapted to receive electronic signals from at least one of the two sensor devices and the to process electronic signals as data. In addition, there is a bidirectional data exchange connection between the processor unit and the memory unit. The processor unit is capable of additionally writing individual data into the memory unit, in particular data on movements which took place only a few seconds or minutes before, before the current time.

At least one of the existing sensor devices is designed to accommodate movements of the emergency indicator. For this purpose, motion sensors can be arranged in the emergency indicator. Alternatively, based on evaluations of global position data, the position, the position or the position change of the emergency indicator, in particular mathematically, can be determined. With the help of the second sensor device, a change to the operating state of the emergency indicator can be made. The second sensor device, for. As a single key, a keyboard or a voice analysis module, can implement information for the processor unit to the effect that an operating state change of the emergency indicator is forwarded to the processor unit. If the sensor device is operated, alternatively the sensor device responds, this signals a signal to the processor unit. The processor unit determines whether the emergency indicator is to be transferred from the current operating state into another operating state.

In a particularly favorable embodiment, a plurality of operating states can be switched on in the emergency indicator. The emergency indicator may reside in a regular operating condition designed as a steady state condition. In the regular operating state, the emergency indicator monitors whether an emergency event is to be identified. If the emergency indicator has identified an emergency event, a change of operating state takes place. However, the situation does not immediately occur at the first change of the operating state that a request for help has been issued. The emergency indicator is in a pre-position operating state. The preposition is a state in which the help request is prepared. The length of the preposition phase can be controlled by timing. If the emergency indicator does not come out of the operating state of the preposition by resetting to the regular operating state, then the operating state of the remote help message occurs when a help request could previously be transmitted successfully. Otherwise, after the end of the prepopulation phase, an operating state phase of the transmission of a help request is assumed.

It is particularly advantageous, and moreover computationally particularly simple, if the processor unit can determine the emergency indication on the basis of movement sequences. For this purpose, the memory unit has deposited at least two motion profiles. Movement profiles can z. B. be a movement profile of a mountain hiker. Another common movement profile can, for. B. be the movement profile of an elderly, only small and few steps behind laying person. Other movement profiles can z. B. motion profiles of a motorist. Similarly, it is advisable to maintain a movement profile of a rock climber or ice climber in the storage unit as a movement profile.

The motion profiles can be maintained both as algorithms and as tabular value systems, value landscapes (multidimensional characteristics and maps) or limit matrices.

Advantageously, the processor unit permanently evaluates the movement that an emergency indicator travels. Because the emergency indicator is intended to be worn on a person's body, or at least in a person's garment or bag, the motion of the emergency indicator will allow the person carrying the emergency indicator to backtrack on a movement of the emergency indicator. The movements of the emergency indicator are similar to the movement profile of the person when used as intended.

One of the sensor devices records the position, movements or movements of the emergency indicator so that at least the processor device can determine a movement profile. If the detected movement deviates from stored motion profiles, possibly interpolated motion profiles or from motion profiles derived from the motion profiles stored in the memory unit, an unusual event is assumed. Instead of an unusual event, under certain circumstances, a bizarre event may be spoken of. Such deviations can z. As increased pulses, shocks, excessive changes in angular degrees, long distances in the same direction within a very short time, z. B. after an unusually high acceleration, or strong oscillating movements. If such a movement is identified as a shock or an impulse, a deviation of the movement into an unacceptable tolerance range is assumed. If such a deviation is detected, and this does not match the data that can be determined from the stored motion profiles, an operating state change instruction to the processor unit of the emergency indicator takes place. After such an event, the emergency indicator persists for a period of time in the event Operating state responsible for initiating an emergency phase. If there are no deliberate interventions, in particular using the second sensor device, then the operating state of the emergency indicator is transferred to a further operating state, in the course of which a transmission of a request for assistance, for example a request for assistance, is made. B. to a telephone emergency service, take place.

The emergency indicator is designed to detect or detect deviations in movement from an existing, acceptable or common motion profile. In a next step, a timer is started. This will expire for a preset time. Is the timer expired, common times for the timer can in the minute range such. B. at one, two or three minutes, an emergency call is transmitted to at least one receiver with the help of the transmitter means. As a receiver, the most diverse receivers come into consideration. A receiver may be an electronic receiver of a telephone control center. In a further embodiment may be provided as a receiver, a PC, which evaluates the data and makes graphically visible, z. B. by position information on a map to be displayed. As an emergency call but also information to a confidant, z. To a doctor.

In the following, advantageous embodiments and developments are set forth, which in themselves, both individually and in combination, can also disclose inventive aspects.

In one aspect, the emergency indicator responds to a peculiar event detected by one or more sensor devices, particularly for measuring motion. The emergency indicator can be a peculiar event z. B. based on exceeding of reference values of a direction of movement in comparison with the measured values or the signals of sensor devices for determining other directions of movement. In a further verification step, relatively large deflections of the movement in one direction with respect to other directions can be interpreted as a peculiar event by the emergency indicator with the aid of stored algorithms.

The emergency indicator has a timer in an advantageous development. The timer can be preset with a time value. If the processor device detects a deviation from the motion profiles that are still considered acceptable, an expiration of the timer is initiated, i. h., the timer starts with its activity. When the detected deviation of the movement from the movement profile, preferably from all available movement profiles, a triggering of the timer is triggered. The timer can be implemented as a timer. Activation of the transmitter means in a time interval determined by the timer is inhibited during the process.

In order to avoid an uncontrolled or an unconscious switching off of an operating state, which is assumed after leaving the regular operating state, there is a securing element for the second sensor unit.

The combinations and embodiments described above can also be considered in numerous other compounds and combinations, eg. B. according to the following diagrams.

The emergency indicator can be accessed by both an "app" for a telecommunications device and a phone equipped with an Android operating system, i. H. as an "App" for a mobile phone, as well as a stand-alone electronic device realize. If the emergency indicator is realized by a separate electronic device, so that the electronic device is to be used exclusively as an emergency message device, this device can be designed for the simplest possible operation, according to a so-called 2-button principle. The stand-alone electronic device, the emergency message device, can be made available to a target group independently of a mobile phone. Target groups are u. a. older people who can no longer be expected to complicate complicated operations. Thus, the emergency indicator can be constructed as a 2-button device.

The independent emergency call device is z. B. clip over a clip on a lapel. After attachment to a person's clothing, such a device, such an emergency indicator, is as self-sufficient as possible. It is also advantageous if the emergency indicator implemented as an "app" on a mobile phone is as simple as possible, i. H. comparable to other popular "apps", is to start. But only by a conscious switch-off sequence, possibly also by several switch-off sequences, the emergency indicator should be stopped again. This safeguard prevents unwanted deactivation in the event of an accident.

It is advantageous if the emergency indicator works with stored motion profiles. The movement profiles can be configured in many ways.

It is Z. B. particularly advantageous if the emergency indicator can distinguish between different movement profiles. Thus, in one embodiment, the emergency indicator may determine whether a person is sitting in a car, making an endurance run or hiking on a mountain. The device excludes from the earlier movement data, in particular from the immediately preceding movement data, z. For example, the data that has been collected in the past two, five or ten minutes, what kind of movement is present.

The device can motion profiles in connection with or based on a movement in spatial coordinates, eg. B. in a classical x, y and z coordinate system (Cartesian coordinate system), measure and determine. From the sensor data in the coordinate directions, z. B. in the Cartesian coordinates, a motion profile is calculated. Alternatively, a spherical space coordinate system can also be used.

The measured movement data, which are assembled into a movement profile, are compared with stored, in particular generally acceptable, motion profiles. Is z. As a blow, an unusual acceleration or otherwise, non-regular movement, so the movement is characterized as an unusual sequence of movements by an identified or measured movement beyond the movement profile. If a movement is identified as an unusual movement due to a movement outside of the stored motion profiles, a timer starts which, for. B. can be preset to one minute. It can also be set to other times, such as just 30 seconds or even 10 minutes. Depending on the progress of the expiry of the timer signals to the emergency call device wearer, such. As a beep, delivered when an unusual event has been detected. This beep can be increased with increasing time, towards the end of the timer time, z. B. more or more and more until the final expiration of the counter. When the time set by the meter has elapsed, an emergency call, e.g. B. by phone or by e-mail, sent to an emergency call, with additional, a salvage, rescue or supportive measures conducive data such. B. GPS data for determining the location of the emergency call sender, who can support a subsequently initiated rescue operation, are transmitted. Are the additional data, z. B. GPS data, not (yet), nevertheless a help request is sent in a first emergency call. Ideally, further emergency calls, later z. B. with the GPS data sent.

The determination of GPS location data is made by a particularly advantageous emergency indicator only when a change of operating state has previously taken place from the regular operating state. Thus, only the areas and electronic modules are supplied with energy that are needed in the respective operating state.

During the countdown phase, when the timer is running, a deliberate deactivation and reset of the device is only possible by a deactivation frequency or a deactivation sequence, the z. B. must include up to three steps or actions. On the other hand, the device is controlled by a single handle, e.g. B. by clipping on a lapel (if it is a stand-alone device) or by tapping on a menu (if it is, for example, is a smart phone), switched on.

The emergency indicator is in one embodiment a portable or mobile communication device.

• • in dem Notfallindikator ein Set von unterschiedlichen Bewegungsprofilen in einem Speicher abgelegt ist,
• • bei Bewegungsabläufen jenseits der vorhandenen Bewegungsprofile und daraus interpolierbarer Daten zunächst ein Zeitglied in dem Notfallindikator gestartet wird,
• • bei Ablauf des Zeitgliedes vollautomatisch auf voreingestellte Notrufempfänger sendende Notrufe (wenigstens ein Notruf, eventuell sogar verschiedene Notrufe wie z. B. zum Hausarzt, zur Rettungsleitstelle und zu einem Pflegedienst) abgeschickt werden.

It is advantageous if

• In the emergency indicator a set of different movement profiles is stored in a memory,
• • In motion sequences beyond the existing motion profiles and data that can be interpolated therefrom, a timer is first started in the emergency indicator,
• • When the timer expires, automatic emergency calls (at least one emergency call, possibly even different emergency calls, eg to the family doctor, to the rescue center and to a nursing service) sending emergency preset receivers are sent.

The different types of input (as simple as possible, only a few steps comprehensive process) and off (only after very specific, selected switching frequencies or sequences) is an advantageous development.

It may be emphasized that in a favorable development, a very specific key combination can be responsible for switching off, while the simplest possible operation for switching on is sufficient.

In other words, the present invention may also be described by individual aspects in terms of keywords as follows:
The emergency indicator can also be called "SWW - Safety worldwide: An active safety system for everyone" or "SWWS - Safety World Wide System" - very handy.

The Emergency Indicator is a security system (SWWS), so all terms used to describe the device, such as the Emergency Indicator, SWWS, and SWW, can be used to some extent as synonyms.

1. Function principle:

The functional principle of the SWWS safety system is explained below.

A global call system ("global positioning system") such as the systems "GPS" or "Galileo" sends a call for help to previously determined recipients in an emergency situation. This call for help can be made by telephone or e-mail to many addressees at the same time and includes, among other things, the exact position of the emergency indicator at the time of sending the call for help or the help request (if all data is available at the time of sending).

• 1. die Grad-Position zwischen der Vertikalen und/oder der Horizontalen (und kann so also ausschließlich oder unter anderem die horizontale oder vertikale Lage des Notfallindikators, wie man es bei Smartphones durch Drehen des Displays kennt, ermitteln),
• 2. die minimale, maximale oder aktuelle Geschwindigkeit (v_min, v_max, v_aktuell). Somit ist eine Bewegung in positiver und negativer Richtung messbar.

• 1. determine the degree position between the vertical and / or the horizontal (and thus, exclusively or among other things, determine the horizontal or vertical position of the emergency indicator, as it is known in smartphones by rotating the display),
• 2. the minimum, maximum or current speed (v _min , v _max , v _current ). Thus, a movement in the positive and negative direction is measurable.

The device automatically detects when an emergency situation exists. Even if the carrier of the SWWS, the emergency indicator, does not have the opportunity to make an emergency call itself, the SWWS does it fully automatically.

• 1. Eine Variante ist, das SWWS als Aufsatz, Zusatz oder Erweiterung für bestehende GPS-Ortungsgeräte, auch GPS-Tracker genannt, auszuführen. Diese Ausführungsform ist nicht so kompakt wie eine Integration in ein bestehendes Kommunikationsgerät. Für bestimmte Personengruppen ist ein GPS-Tracker nicht alltagstauglich, für andere jedoch gängig.
• 2. Eine andere Variante ist es, das SWWS als komplett eigenständiges Gerät auszuführen. Ein Vorteil dieser Ausführungsvariante liegt darin, dass diese Ausführungsform anpassungsfähig für jedermann, klein und handlich, bedienbar und einstellbar am PC (personal computer), z. B. über USB-Verbindungen, wie MicroUSB („Universal Serial Bus”), ist.

The emergency indicator can be realized in different variants:

• 1. One variation is to run the SWWS as an attachment, addition or extension to existing GPS tracking devices, also called GPS trackers. This embodiment is not as compact as integration into an existing communication device. For certain groups of people a GPS tracker is not suitable for everyday use, but is common for others.
• 2. Another variant is to run the SWWS as a completely separate device. An advantage of this embodiment is that this embodiment is adaptable for anyone, small and handy, operable and adjustable on the PC (personal computer), z. Via USB connections, such as MicroUSB (Universal Serial Bus).

2nd technique:

The technique of the security system SWWS can be understood by the following explanations.

Some GPS trackers have by themselves z. For example, the security concept "At the touch of a button he (the GPS tracker) sends an SMS including a position to up to 3 stored numbers." Due to the triggering key concept, the security idea works in many cases, but for example when a heart attack, a Accident, crash into a crevasse, flushing away from a ship, fainting, disturbance of consciousness or serious accident, triggering and transmitting the help request is questionable. An independent response of the emergency indicator is helpful.

As a 3-axis accelerometer module, there are already known, fully populated mini-boards with acceleration sensors (for example, ADXL330KCPZ, X-Y-Z), voltage regulator and reverse polarity protection diode. A 3-axis accelerometer module can be used, for example, in acceleration measurement, in alarm systems, for vibration and inclination measurement, etc. Such a module, which is known from the aforementioned technical fields, can also be used in an emergency indicator according to the invention.

• - Sensitivity 300 mV / g
• - Pin assignment printed on the board
• - Board dimensions 20 × 20 mm

4. Applications:

A particularly advantageous task of the emergency indicator of the security system SWWS is to get help fully automatically in a crisis situation.

There are various uses possible, as the following examples are intended to show.

Application 1:

The security system SWWS is suitable for every athlete worldwide, who attaches importance to security, so for each of the z. B hiking, mountain climbing, biking, jogging, skating, sailing ....

Possible use 2:

The SWWS safety system is suitable for every motorist worldwide who values safety. In a car crash, an accident, a heart attack, etc., every minute is precious, and help can not usually be fetched on its own, because one is injured. The SWWS is in the vertical state before starting the journey, z. B. seat state, activated. In an accident, the speed is reduced abruptly. In addition, the vertical sitting posture may no longer be present. It is automatically requested help in 2 ways.

Application 3:

Employees in companies that work alone would be covered. Without warning device, it is prohibited by law alone z. B. to work in a hall.

Possible use 4:

In an accident, heart attack, etc. every minute is precious, and help can usually not be fetched by yourself, because you're injured. The SWWS is in the vertical state, z. B. seat state, activated. In an accident you fall z. B. from the chair and it is automatically requested help.

• – der Wanderer macht eine Pause, setzt sich auf eine Bank („best case”) => der Wanderer schaltet (einfach) per Taster den SWWS auf „standby”
• – der Wanderer hatte einen Herzinfarkt, er fällt um („worst case”) => der SWWS fordert nach einer Sicherheitszeit mit Akustik selbsttätig Hilfe an

Case 1 is explained below with reference to a walker:
When the speed reaches a maximum of z. B. 5 km / h back to "0 km / h", this can have several causes:

• - the hiker takes a break, sits down on a bench ("best case") => the hiker switches (simply) by pressing the SWWS on "standby"
• - the hiker had a heart attack, he falls over ("worst case") => the SWWS automatically calls for help after a safety period with acoustics

• – der Autofahrer fährt an einen Rastplatz und macht eine Pause („best case”) => der Autofahrer schaltet per Taster den SWWS auf „standby”
• – das Fahrzeug hatte einen Unfall, der Autofahrer ist eingeklemmt und bewusstlos („worst case”) => der SWWS fordert nach einer Sicherheitszeit mit Akustik selbsttätig Hilfe an

Case 2 is explained with reference to a motorist:
If the speed increases after a maximum of z. B. 100 km / h back to "0" (0 km / h), this can have several causes:

• - the driver drives to a rest area and takes a break ("best case") => the driver switches the SWWS to "standby" by pressing a button
• - The vehicle had an accident, the driver is trapped and unconscious ("worst case") => the SWWS automatically calls for help after a safety period with acoustics

The speed is a decisive measure here. If the speed changes abruptly in time t, there is an emergency situation, but if it changes continuously, this is just a normal braking operation, eg. B. at a rest stop. Here then the braking delay of the last 5 s is important or a very good clue.

• – der Bergsteiger macht eine Pause, er hängt in der Wand oder er sitzt auf einem Felsen („best case”) => der Bergwanderer schaltet per Taster den SWWS auf „standby”
• – der Bergwanderer ist abgerutscht, er hat plötzlich auf 50 km/h oder mehr beschleunigt und braucht Hilfe => der SWWS fordert nach einer Sicherheitszeit mit Akustik selbsttätig Hilfe an

Case 3 is explained with reference to a mountaineer:
If the speed increases after a maximum of z. B. 0.5 km / h back to "0" (0 km / h), this can have several causes:

• - the mountaineer takes a break, he hangs in the wall or he sits on a rock ("best case") => the mountain hiker switches the SWWS to "standby"
• - the mountaineer has slipped, he has suddenly accelerated to 50 km / h or more and needs help => the SWWS calls automatically for a safety time with acoustics help

By using a 3-axis motion sensor as one of the electronic modules, the emergency indicator offers more possibilities, as exemplified by the following cases:
Case1: A hiker falls vertically into a crevasse. Thus, his posture is still upright. He still has 90 degrees (90 degrees to the ground), but the speed has dropped to 0 (0 km / h). Thus, the emergency has occurred.
=> the SWWS automatically calls for help after a safety period with acoustics
Case 2: A group drives by car and has an accident, so the speed is suddenly reduced to "0 km / h".
=> the SWWS automatically calls for help after a safety period with acoustics

There are still many case studies and applications that can be presented as well as the examples presented above.

5. Hardware:

Various hardware versions of the SWWS security system are possible. Hereinafter, individual embodiments will be explained.

The SWWS can be set via a mini / micro USB interface with the necessary parameters via PC program. The processor (eg EEPROM) stores all relevant data and settings permanently.

6. Advantages of SWWS:

One of the advantages of the security system SWWS according to the invention is that it is "active" anytime, anywhere, ie. H. can be operational and fast, safe and independent, d. H. without the help of a user, can call for help.

7. Exclusion of use cases for SWWS:

The SWWS can, as shown above, be used almost universally. Restrictions in the application could be the more limited possibilities in certain exceptional situations. Such exceptions, where the SWWS may be limited or ineffective, could be: For example, be on North-South Pole expeditions or mountaineering like climbing Mount Everest or being deep in the jungle.

Another noteworthy limitation to the use of the SWWS could be that the call for help might be received, but the track could be too far, impassable, too dangerous for rescuers using their lives, or anything similar.

8. Mechanics:

The mechanics of the safety system SWWS can be described in 2 variants.

Variant I: The SWWS is called extra, d. H. separate, stand-alone unit used.

In this case, the following prerequisites must be met:

• - The housing should be small, possibly waterproof.
• - It should have a simple clip (such as a hair clip) as a bracket to attach it anywhere quickly, such as the backpack, the sail, the sweatpants, the neck support of the car, etc.

Variant II: The SWWS is used as an attachment.

In this case, there are hardly any space requirements.

• – ein Knopf bzw. Schalter zur Aktivierung bzw. Deaktivierung muss außen angebracht sein. Hierbei handelt es sich um eine schnelle Variante zum Ein-/Ausschalten.

A general, advantageous requirement in this case is:

• - A button or switch for activation or deactivation must be attached to the outside. This is a fast variant for switching on / off.

9. Software:

The software should permanently measure the vertical / horizontal position in the "activated state" and also the speed when using a 3-axis motion sensor (v _min / v _max / v _current )

The software has nothing to do in "standby" status, except to read the "Active" button.

• – nach der Aktivierung zum Starten des internen Mess-Modus
• – im Falle der Erkennung einer Notsituation, Ausgabe eines Warnhinweises für die Zeit t, bevor die Notsequenz an die eingestellten Empfänger gesendet wird.

The software has different timeouts, at different times, as listed below:

• - after activation to start the internal measuring mode
• In the event of an emergency situation being detected, issuing a warning for the time t before the emergency sequence is sent to the set receivers.

The software could also automatically detect that the user is in standby when the speed drops to "0" (0 km / h), but the user is still vertical, ie. H. z. B. sits (except the user falls vertically, for example, in a crevasse).

• – Wandern, Joggen etc.: Hier kann die Beschleunigung positiv/negativ eingegrenzt und auf Plausibilität geprüft werden, aber auch GPS ist sinnvoll.
• – Autofahren: Hier kann die Beschleunigung positiv/negativ eingegrenzt und auf Plausibilität geprüft werden.
• – Segeln: Hier kann die Beschleunigung positiv/negativ eingegrenzt und auf Plausibilität geprüft werden, aber auch GPS ist sinnvoll.
• – Sport allgemein: Hier sollte ein GPS mit an Board sein, da die Möglichkeiten der typischen von der Sportart abhängigen Bewegungen von Sportart zu Sportart unterschiedlich sind.

The software has several application modes, such as:

• - Hiking, jogging etc .: Here, the acceleration can be positively / negatively limited and checked for plausibility, but also GPS makes sense.
• - Driving: Here the acceleration can be limited positively / negatively and checked for plausibility.
• - Sailing: Here, the acceleration can be limited positive / negative and checked for plausibility, but also GPS makes sense.
• - Sports in general: Here, a GPS should be on board, since the possibilities of the typical sport-dependent movements vary from sport to sport.

10. Further ideas & possible uses:

For the safety system SWWS further applications are conceivable. In the following, individual design or application variants are presented by way of example.

A) Possible uses

If the emergency indicator is implemented by means of an APP ("application"), it can also be used and used on smartphones with GPS.

Brief Description

The present invention may be better understood by reference to the accompanying figures, which set forth by way of example particularly advantageous design possibilities without restricting the present invention thereto

1 an embodiment of an emergency indicator,

2 a further embodiment of an emergency indicator on a smartphone with an operable screen display in a first operating state and

3 the embodiment of 2 in a second operating state.

figure description

1 shows an emergency indicator 2 as a stand-alone device in the housing 10 with a rearwardly extending mounting bracket 12 with which the emergency indicator 2 z. B. attachable to a person's clothing. The operation of the mounting bracket 12 activates the emergency indicator in a start state where motion sensor data is acquired and evaluated with algorithms for the motion profile. The motion sensor and processor unit (not numbered) are located inside the housing 10 , The operating status detector 8th Optically indicates that the emergency indicator is in a startup mode, which may also be referred to as a standby state. When a detected deviation of a movement from a stored motion profile, a safety mode is started and there is a change in the optical display of the operating state detector 8th which is also made audible with increasing beep volume. A switch 6 as a second sensor device makes it possible by operating the switch 6 to return to the starting mode within a time interval of 2 minutes. Without operating the switch 6 is from the emergency indicator 2 sent a help request after two minutes.

Another embodiment of an emergency indicator 102 is in the - hereby jointly presented 2 and 3 shown. Shown is the touch-sensitive display 106 a smartphone with a display 104 a startup mode 108 in 2 and an ad 104 ' a security mode 108 ' in 3 , which are each created by a software on the processor unit of the smartphone. The smartphone comes standard with a motion sensor that detects a regular, upright posture of a person wearing the smartphone. In a deviation from the regular attitude, which is determined by an algorithm, the emergency indicator goes 102 in the security mode 108 ' above. In the security mode 108 ' counts a timer 112 the time-out of 44 seconds until an SMS emergency call is sent to two pre-programmed telephone numbers, such as an emergency number and a telephone number of a trusted person. A series of three touches on the display 106 (Display area 106 ) in the safety mode display 108 ' leads to a reset of the timer 112 , a suspension of the timing and a transition of the emergency indicator 102 in the start mode 108 ,

The design options shown in the individual figures can also be interconnected in any form.
