DETAILED DESCRIPTION OF THE INVENTION The present invention generally relates to systems, methods, and apparatus comprising transmitting devices for sustained wireless transmission of energy waves for the protection of objects, individuals, and entities, such as humans, livestock, and objects.

Systems, methods and devices for protection, also known in the art, consist of a label attached to an object to be monitored and a transmitting device for generating a magnetic field in a suspended robot in the area under surveillance, the label being , carries a device wire that interacts with the local evacuation caused by the device (N) at the exit port. Only unlabeled objects can freely move through the area without generating an alarm signal. can pass through.

Other imaging systems, methods and apparatus known in the art include electromagnetic radiation emitted across the area.
The area under surveillance is covered with dead metal, and a signal indicating the presence of a moving or stationary object is generated indiscriminately, regardless of the identification of the individual.

It is therefore an object of the invention to provide a system, method and device for protection! , in which case the object to be protected is not changed in °C by its movement within the area under surveillance or by passing through and exiting the area.

Another object of the invention is to provide a system, method and apparatus for unobtrusively distinguishing protected objects in an area under surveillance.

TECHNICAL FIELD The present invention relates to a system for protecting objects, individuals and entities such as humans, domestic animals, and objects.

According to the invention, the system for thermal protection comprises a central station with equipment on the radio receiver 4 and at least one mobile station with a radio receiver for transmitting signal energy! and the wireless receiving device is adapted to detect the transmitted signal energy, and
a boundary device that rejects any detection signal below an adjustable threshold level, a trigger device activated by signal energy above the threshold level, and an alarm device activated by the trigger device. .

The invention has the advantage that, for its implementation, it requires little space both at the transmitting end and at the receiving end. Its application yields particularly satisfactory results when it provides the device of an auxiliary station to a playing child and the device of a medium-heat station to its guardian.

The present invention will be described in detail below with reference to the accompanying drawings.

In FIG. 1, a transmitter, generally designated 1o, is
It consists of a transmitting device 11 and an antenna device 12, which are interconnected to connect and transmit electromagnetic energy waves, making it possible to confirm, for example by transmitting one continuous wave of one specific frequency. Has energy and information. The transmitting device is provided with an on-off switch device, which can be activated from an energy source (not shown).

Thus, the transmitter 10 is independently formed and
It can also be configured as a portable device, for example as a piece of jewelry or a label, and attached to any carrier to be protected.

A receiving station or central station is shown in FIG. 1, generally designated by the reference numeral 20, and includes a receiving antenna 21, a detection or identification stage 22 tuned to the energy waves transmitted by the transmitter, and a boundary adjustment device 23 consisting of a variable potentiometer. and a relay coil 24, which is controlled by the relay coil 24 and is adapted to close an interrupter in a circuit consisting of an alarm device 27 and an energy supply device 28 to the alarm device, and a relay armature 25. It's getting better. Thus, the boundary armor [of sufficient strength of 25! The spill force causes armature 25 to interrupt the alarm circuit.

The boundary PII adjusting device 26, the relay coil 24 and the relay armature 25 form a boundary and trigger device in the receiver and have adjustable boundary levels.

As a result, the alarm device 27 will be activated if not enough signal wave energy is received from the transmitter 10, ie below the level set in the boundary adjustment device. If the transmitter 10 is further away from the receiving device 20 by more than a predetermined distance, the alarm device is activated.

Such a predetermined distance can be selected by adjusting the level adjustment device.

FIG. 2 shows another embodiment of the system for wireless protection according to the invention 9, an auxiliary radio station 6o.
, the transmitter 62 is controlled under the Korg 61. At the central radio station 40 , a receiver 41 is configured to receive encoded signal energy from the transmitter 32 . Decoding the received signal energy at receiver 41 generates a synchronization signal by pulse generator 42. The generated synchronization signal is applied to adjustable time delay device 44 and one of the two inputs of AND gate 470. The time delay device is arranged to indicate a period according to the elapsed time of the signal energy propagating from the transmitter to the receiver if the transmitter is at a predetermined distance from the receiver. . The selected adjustments are made from a zero setting indicating synchronization between the synchronization system and the clock from clock 45, e). Remataimink during this initialization period.

Under the control of device 146, during such an initial start period, normally open switch 51 is closed, connecting the time delay device output to clock 45.

Clock 45 operates at the same speed as the synchronization signal generated in pulse generator 42. The clock pulse is applied to the other input of AND gate 47.

The clock is synchronized with the synchronization, ξ, and
Only when the gate 47 is reached can the maple storage device 4 be reached.

Clock pulses are stored in storage device 48 to activate alarm device 49.

Thus, at the point at which the auxiliary station carried by the object under surveillance reaches a position at a predetermined distance from the central station, the central station's ``# information'' command 49 is activated.

This also means that the object of congratulation is out of reach, and the danger is -1%.
It means something.

In this embodiment, the setting of the number of clock pulses to be accumulated in the storage device 48 which causes the alarm device 49 to operate serves as a threshold level.

Optionally, the central station comprises a signal wave energy transmitting device and the secondary station comprises a receiving device t adapted to receive such transmitted signal wave energy. FIG. 6 shows a variant of the embodiment of the system for protection according to FIG. The central station 60 comprises a transmitting device 61 configured to transmit cis-type signal wave energy at predetermined intervals ↑). A receiver 51 at the secondary station 50 is configured to receive the signal wave energy transmitted by the transmitter 61 of the central system. The configuration of receiver 51 is generally the same as that shown in central station 20 of FIG. The example of the 1st corridor shown in Fig. 6 is 11-information device 2
7 differs in that the transmitter 52 is used to transmit signal wave energy for a limited period of time, preferably consisting of two pulses transmitted by a central station. The configuration of the receiver 62 formed in the central station 60 is also identical to the configuration of the receiving device shown in FIG.

If receiver 62 fails to receive signal wave energy above a threshold level from transmitter 52, an alarm system in the central station is activated.

Above, the preferred embodiment is described using magnetic waves to interconnect the central station (receiver #) and the auxiliary station (transmitter).

One can imagine the use of infrared wave energy or ultrasonic energy to provide such an interconnect, primarily to avoid interference.

The central station may also include an alarm device, each responsive to one of a plurality of auxiliary stations, for tracking a plurality of individuals or entities to be protected! Wear. It can be conveniently formed into a portal pull type and integral package for use with receivers and alarms.
