Description

DESCRIPTION
The present invention relates to a portable electronic security device, which makes it possible to ensure, whatever the place, and during any movement, the protection of elements liable to move or to be moved (living beings, objects), in establishing a counter zone, and automatically entering into function as soon as the monitored element crosses the limits of this zone.

The current state of the art in electronic security systems is represented by t
. Devices protecting against burglaries t
- with perimeter detection î photoelectric cells, shock or pressure detectors, electric6 or magnetic opening contacts which are placed at all exits likely to be forced
- with volumetric detection :: infrared detectors sensitive to any variation of heat caused by the presence of an intruder, ultrasonic or icro-wave detectors emitting and receiving their own signals in return (any housing passing through this beam waves creating a phase shift on reception and triggering the alarm)
All these devices, very effective in signaling any break-in, are fixed, require a fairly long installation, a studied layout, delicate adjustments, and their installation must be restarted each time when moving to a new place.

 Portable devices allowing a person, victim of an assault, to set off a powerful alarm siren.

If they have the advantage of being able to be carried with you, these devices unfortunately do not work automatically (they require that the victim presses a button himself to trigger the alarm);
Devices to facilitate the search for missing persons (distress beacons worn by exploration teams, miniature transmitters worn by mountaineers who risk being buried under an avalanche).

 These devices, very effective in enabling the emergency services to locate the area to be invested more quickly, thanks to the use of a very sensitive receiver, the sound signal intensity of which increases as the rescuers approach the victim, do not persevere to act as preventive safety systems, and to prevent an accident from occurring.

 The device according to the invention overcomes the deficiency represented by current electronic security systems in this field.

 According to a preferred embodiment, it in fact comprises a portable and miniaturized box containing a receiver circuit connected to an output device (signal or siren of alarm, of adjustable intensity in particular for this preferred embodiment by via a contactor relay, and which is carried by the controller element - or which is placed in the center of the zone to be controlled and on the other hand a portable and mimiaturized box enclosing the transmitter circuit, and which is carried by the controlled element. Such a tif arrangement allows aimai, whatever the place (outside, as inside spaces), and during any movement, the protection of vents likely to move or to be moved, establishing a counter zone determined by the range of the transmitter circuit, and automatically activating the output member function, as soon as the monitored element crosses the limits of this zone i As soon as the receiver circuit receives plus the signal of the miniature box containing the transmitter circuit, because the element (living being, object) which carries it on it moves away is lost or is victim of an attempted theft, the receiver circuit does not send more current at the relay-contactour which "picks up n and comes to establish an electrical contact which instantly turns on the output device.

The miniature box containing the receiver circuit and the miniature box containing the transmitter circuit can be used reversibly at the level of the control element and the controlled element:
. Box containing the receiver circuit and the output device carried by the person responsible for monitoring - or placed in the center of the area to be controlled - and box containing the transmitter circuit carried by the monitored element, when the latter is small or that you don't want to cause him any discomfort.

. Box containing the receiver circuit and the output member carried by the monitored element, and box containing the receiver circuit and the output member carried by the control element - or placed in the center of the area to be controlled - to allow
- To immediately locate the object which has crossed the limits of the controlled area, and / or to dissuade more easily a person who tries to steal it;
- To monitor several elements at the same time (for example, several children or several objects) t the box containing the transmitter circuit being carried by the controller element - or being placed in the center of the area to be monitored - and a box containing a circuit receiver being carried by each of the elements to be monitored.

(As soon as one of the monitored elements is no longer in the controlled area, the box containing the receiver circuit it carries on it no longer receives the signal from the box containing the transmitter circuit, which instantly activates the organ Release.

 According to a variant, the miniature box containing the transmitter circuit can transmit a signal constituted by an emission of a certain number of pulses per unit of time (example: one pulse every three seconds) to allow the consumption of the power to be greatly reduced. battery. The receiving circuit is then coupled to a sensor-comparator of pulses received per unit of tempo, which automatically activates the output device if it does not receive a new pulse after a determined time (by resuming the previous example if it has not received a new pulse after three seconds have passed).

According to a variant, the transmitter circuit can have an adjustable range, depending on the dimensions of the area which is to be controlled:
- A few meters: to prevent, for example, the loss or theft of a young child in a crowd, or of an object carried with you (bag, briefcase, suitcase ...), or to signal, inside premises in particular, if a child has left his play area without risks - his bedroom for example -, to go to a dangerous place - the kitchen, the bathroom, the door to the street, a place containing dangerous objects or toxic products ...

-Up to several tens of meters: to allow, for example, the supervision of a child outside, in a public or private garden, on a forest, in the mountains, in the countryside (by taking office as soon as a young child, for example, has left the play area assigned to him to head towards a body of water, a busy road, a place where he risks falling into a void ...), or to allow for example the surveillance of an object or an exhibition machine, intended to be handled freely by the public in a stand, a fair.
- And even up to several hundred meters for exceptional long distance surveillance applications.

 According to a variant, the monitoring can be personalized thanks to the presence of a counter-comparator of pulses received per unit of time and of buttons making it possible to code the number of pulses to be received and to be transmitted per unit of time, by the user. itself (or, fixed during the construction t of devices with a dozen different codes, for example, being put on the market to make practically zero the probabilities of having an interference problem, when another transmitter element operates accidentally or intentionally at the same time in the controlled area).

 The monitoring of the device can also be personalized by a user of the transmitter circuit and the receiver circuit on a very precise frequency, which can be determined by the use of different quartz crystals, and adjustable by the user thanks to a button on the transmitter or on the receiver or not adjustable (fixed during the construction of devices with ten different frequencies for example, for low cost models, being placed on the market to make as previously practically zero the probabilities of having a interference problem when another transmitting element operates at the same time in the monitored surface).

 The output device, instead of being constituted according to the form of preferential marking by an audible signal or an alarm siren of adjustable intensity, can be constituted according to a variant by an emergency stop on a dangerous machine, or by one or more electric motors to allow for example to raise or lower a safety barrier, to automatically bring a machine - industrial robot in particular - in the evolution zone which has been assigned to it, to cause a slowdown progressive of a dangerous machine or machine ...

 According to a variant, the transmitter circuit can be connected to additional detectors which will aim, even if the monitored element is still in the controlled area, to interrupt, if they are stimulated, the signal between the box containing the transmitter circuit and the box containing the receiver circuit, which will instantly trigger the output signal.

 Finally, according to a variant, the - or the - relay (s) - contactor (s) can be electronic and appear for example in the circuit of an electronic quartz watch (or of any usual object t pocket calculator, pen, watch, keychain, toy) which, apart from its normal functions, will be responsible for monitoring the controlled element. The receiving circuit can also appear in a housing provided for this purpose of a belt worn by the controlled element (child in particular) or of a collar worn for example by a monitored animal.

 Conversely, due to the reversible use of the receiving circuit and the netting circuit of the controlled element or of the controlling element, it is the transmitting circuit which can be integrated into the circuit of a quartz watch, d '' a pocket calculator, a watch pen, a toy, a keychain. .

 And in the same way, the transmitter circuit can appear in a belt, a collar worn by the controlled element, or be in the form of a "emitting patch fixed on the element to be controlled.

 Figure i shows the housing containing the receiver circuit.

 Figure 2 shows the housing containing the transmitter circuit.

 The element represented in FIG. I comprises a box (i) enclosing a receiver circuit (2) of radio, sound or light electromagnetic waves (whatever their frequency or their wavelength) with adjustable frequency (3) or no, coupled or not to a counter-comparator of pulses received per unit of time (4) adjustable (5) or not and connected to one - or more - output device (s) (6) via one - or more - relay (s) - electromagnetic (s) or electronic (s) contactor (7).

The element shown in FIG. 2 comprises a box (8) containing a transmitter circuit (9) with range (10), frequency (11) and number of pulses emitted per time unit (12) adjustable or not , and can be connected to additional detectors (13)
The control zone of the portable safety device has its dimensions which are determined by the range (10) of the box (8) containing the transmitter circuit (9). As long as the receiver circuit (2) receives the signal from the box (8) enclosing the transmitter circuit (9), it sends current to the relay-contactor (7) which therefore prevents the electrical contact being established which activates the output member (6).

As soon as the receiver circuit (2) no longer receives the signal from the box (8) containing the transmitter circuit (9), because the monitored element serves as the controlled zone, it no longer sends current to the relay contactor (7) which "picks up" s which establishes an electrical contact which instantly activates the output member (6).

 The portable electronic security device, object of the invention, is intended for the protection of elements liable to move or to be moved (other living things, objects).

Here, by way of nonlimiting examples, possible embodiments of the invention e Portable electronic device for alarming and protecting living beings (especially young children, but also elderly or disabled people, the mentally ill, animals , ...)

THIRD POSSIBLE FORM OF IMPLEMENTATION OF THE INVENTION
PORTABLE ELECTRONIC ALARM AND ACCIDENT PREVENTION DEVICE
WORKING TEETH AND OCCUPATIONAL DISEASES.

The triggering of an alarm when the monitored element is no longer in the zone controlled by the device can also be used for the protection of dangerous objects which can only be moved or moved in a given space, and which must not on no case be transported outside the limits of the controlled area for safety reasons.

The equipment used n its operating principle is the same as that in the first two possible embodiments of the invention:. As long as the dangerous element remains in the zone controlled by the device, the link between the emitting element and the receiving element of the security share device is not interrupted, and the alarm signal is not not engaged.

 e If, to the detriment of safety, the dangerous element is no longer in the zone controlled by the device, the link between the receiving element and the transmitting element is interrupted and the alarm signal (or a device emergency stop, or progressive braking) is immediately triggered.

In the same way, when using dangerous machinery, or when driving vehicles (self-propelled carriages, tractors, trucks, covers ...) an emergency stop, or progressive braking, or even a automatic piloting bringing the machine or the vehicle to the safety position (thanks to the possible coupled use of different detectors: radars, ultrasound, and additional motor components) can be activated by the electronic alarm and safety, when the monitored item is no longer in the area controlled by the device.

The fact that the device works on a “signal cut-off” makes it possible to use certain complementary detectors here: Fall detectors, loss of consciousness (electronic detectors sensitive to a change of position, or electrical detectors constituted for example by a mercury bubble that can move between two electrical terminals of an ampule: in the event of a fall, fading, the mercury bubble moves in the direction of the change of position in the bulb, and comes to establish a contact that interrupts the signal between the receiving element and the emitting element of the safety device, which triggers an alarm, or the functioning of a driving organ which will cause an emergency stop, or a pre-fattening braking or automatic piloting or indeed a micro injection, at a given ondreit of the body of a medicinal substance which will fight center the door of knowledge of the subject and maintain a state of minimum vigilance to avoid the accident.

In the same way, other complementary detectors can be used: - Miniature and portable ECG detector taking the cardiac impulses thanks to two electrodes fixed by adhesive on the left side of the theraxou capturing the cardiac impulses thanks to a mechanical assembly ge @ re dé with ceudre, fixed on a deigt and recording the pulsations of the blood at the level of the deigt, varying with the rhythm of the cardiac beats, thanks to a luminous micro-barrier constituted by a light source and a photoelectric cell. , cardiac arrest or major rhythm disturbance, the detector interrupts the signal between the receiving element and the emitting element of the security device, which will trigger an alarm (sound: clackson, siren and light: lighting elignetant lights of the vehicle for example ...) and / or the operation of one or more meters which will cause an emergency stop, or progressive braking, or autopilot Atic using different obstacle detectors for acting on the driving parts of the vehicle or of the machine, in order to bring it without danger towards a safe position.

NB: In the same way, the portable electronic security device can trigger or a given place on the body a medicinal substance which will act as an emergency on the cardiac accident.

- Miniature and portable EEG detector highlighting the brain waves thanks to two electrodes, one of which is fixed on the occiput and the other on the pavilion of the ear t In case of sudden variation of the brain waves, linked to a accident, the detector interrupts the signal between the receiving element and the emitting element of the security device, which will likewise trigger the alarm and / or the operation of one or more meters which will cause an emergency stop, or progressive braking, or automatic piloting.

If suddenly the person is no longer in the counter zone, the connection between the receiving element and the transmitting element is interrupted and the alarm signal is immediately triggered; Fields of application This fourth possible form of reallocation of the invention t. Staff, rescuers, firefighters intervening in completely smoky places: cellar fires, burning houses and buildings, interventions in places where there is a risk of emanating toxic gases, toxic respiratory agents, in tanks, tanks intended to contain toxic, flammable or explosive products (the portable electronic security device then being protected by an explosion-proof device), traviax carried out in mines, quarries, buildings and public works. Sportsmen (skiers, mountaineers, explorers ...) evolving in avalanche terrain, at high risk of landslides ...

In this fourth possible embodiment of the invention, a box containing both a transmitter circuit and a receiver circuit coupled to an alarm via a relay (electrical, electromagnetic or electronic) can be used: each member of the intervention group then loses a "transmitter-receiver-relay-alarm" box. The rescuer who leaves as a scout in a dangerous zone puts his device on the "reception" position using a push button and the others put the device in the "emission" position. Thus, neither the rescuer who left first is tieti- me of an accident, the fact of no longer being in the controlled zone will trigger the alarm and will also allow other rescuers to locate it thanks to the sound emitted by the siren, which will signal the place where I find the victim. When it is the turn of the other rescuers to cross the difficult passage, the rescuer who is broken down first puts on his portable device of security on "transmission" and who or those who go to the "reception" position, and so on ...

An emergency button, present both on the transmitter box and on the receiver box, or on the "transmitter-receiver-relay-alarm" box, allows me to import what moment to immediately and immediately activate the alarm siren if needed.

 On the other hand, the fact that the security device works on "signal cut" 1 allows the use of certain additional detectors c. Fall, malzise, knowledge gate detectors (electronic detectors sensitive to a change position, or detec electric towers constituted for example by a bubble of mercury which can move between soft electrical terminals of a small tube t in case of fall, fading, the bubble of mercury, sene the effect of gravity, linked to the change of position of the Small tube, it will slide and will come into contact with the second electrical berm, which will establish an electrical contact which will interrupt the signal between the receiving element and the emitting element of the device , which will set off the alarm, the functioning of a motor device which will, for example, come from a micro-injection at a given place in the body of the victim of a medicinal substance which will fight against the loss of consciousness.

In the event of illness, cardiac accident, or major heart rhythm disorder, the detector interrupts the signal between the receiving element and the emitting element of the security device, which will trigger the alarm and / or the operation of a motor element which will cause, for example, a micro-injection of a medicinal substance fighting against the medical emergency and thus making it possible to avoid the worst while awaiting the intervention of specialized emergency services.

. Miniature and portable EEG detector highlighting brain waves thanks to two electrodes attached to the body: in the event of sudden changes in the brain glands, the alarm is triggered and / or a drug substance is injected as before.

The box (i) containing the receiver circuit (2) can also appear in the housing provided for this purpose of a belt worn by the controlled element (child word like) specially designed so that the box (1) containing the receiver circuit (2) and the outlet member (6) is effectively protected from shocks and cannot in any case risk generating or injuring its user (child in particular) during his movements, thanks to the presence in the belt of a protective padding which exactly compensates for the extra thickness represented by the presence of the case (i) and causing an immediate triggering of the output member (6) if the controlled element (child in particular), or any foreign person tries to loosen the belt whose closure system can be represented by an electrical contact, automatically triggering the output member (6) if an attempt is made to unbuckle the belt.  10) Characterized by the fact that the contactor relay (7) can be elec truncated and appear in the integrated circuit of an electronic quarter watch (or of any usual object i pocket calculator, pen-watch, key ring or toy ), which, apart from its normal functions, is responsible for monitoring the controlled element (which carries s: r him "(lénent (8) containing the transmitter circuit (9)), thanks to the presence of a receiver micro-circuit (2) connected via the electronic contactor relay (7) to the output member (6) of the portable element in which it is integrated (for example :: output member (6) the receiver represented by the electronic alarm clock of a quartz watch, or by the audible "beep" of an electronic calculator), In the same way, the - ####### the element (8) containing the transmitter circuit (9) can appear in the housing provided for this purpose of a belt worn by the controlled element (young child in particular ), provided with a protective padding and a closure system represented by an electrical contact which, if an attempt is made to unbuckle the belt, instantly stops the electrical supply to the transmitter circuit (9) t the case (i) enclosing the receiver circuit (2) no longer receiving the signal from the transmitter circuit (9), immediately activates the output member (6) via the relay-contactor (7). Conversely, due to the reversible use of the receiver circuit (2) and the transmitter circuit (o) at the level of the controlled element or of the controller element, it is the transmitter circuit (9) which can be integrated into the circuit of an electronic quartz watch (or of a pocket calculator, a watch pen, a key ring or a toy) The element (8) containing the transmitter circuit (9) can also be in the form of a "transmitter patch" fixed on the element to be checked (small object, wallets, important documents ...) , or, in the field of industrial robotics for example, on objects to be recognized in order to be able to avoid them, or on the contrary to be able to move towards them, to transport them, or on certain parts of these objects which are to be handled. These "emitting pads" comprising on their lower face an adhesive substance which makes it possible to stick them, like the electrodes of an electrocardiograph on the element to be monitored.  speaker of the device which interrupts the broadcast or the music being listened to to give an audible alarm signal. Finally, and above all, due to the pleasant nature of the monitoring, the relay-contactor (7) relinnt the receiver circuit (2) to the output device (can be integrated into a transistor station (or a portable walkie-talkie , an electronic watch coupled to a receiver, a tape recorder or an electrophone) t which allows, while listening to the program or the music of your choice, to monitor an element which carries the emitting circuit (9) t as soon as the receiver circuit (2) no longer receives the signal from the transmitter circuit (9) (that is, as soon as the monitored element is no longer in the controlled area), it no longer sends current to the relay-contactor (7) who "picks up" and laugh establish an electrical contact which instantly activates the output device (6) t in this case the top
