Description

! The present invention relates to a device (TBS) for

  radiocommunication, compact, portable and wireless, consisting of a radiotelephone and a radio beacon managed in a box fitted with a keypad. The telephone5 operates in a conventional mode with transmitting and receiving bodies. The beacon can be triggered manually with one of the specific buttons to alert the calvier or automatically with one of the device detectors (TBS) in the event of danger. Each coded alert radio signal emitted by the device (TBS) allows a research station to know the identity of the subscriber, the nature of the danger encountered and the location of the device (TBS). The activation of a special key on the keyboard makes it possible to obtain its location on the device (TBS). The emission15 by a research station, of a specific coded radio signal, recognized by the device (TBS), automatically activates a radio emission from the device (TBS), allowing the station to locate it remotely. The reference of the location coordinates is terrestrial or any other spatial reference. With a socket and interfaces, the device (TBS) can communicate alerts to supply chain networks, or become the radio relay of a fixed monitoring installation not connected to a

  communication. The radio frequencies are analog, digital or analog-digital depending on the communication networks used.

iri

  According to the main description on pages 1/3, 2/3 and its

  variants page 3/3, the telephone and the device beacon (TBS) have the following main and common components: A socket (PC) to recharge the battery (PI) and a socket (PR) and interfaces (IN), a control unit (MP), a memory (ME) for storing data, a smart card reader (LE) with its smart card (CA), an audible warning (SO) which can be closed by a plug (BO ), or a drawer cover. A warning light (LA). The antenna (AN), the keyboard (CL) which includes specific or common keys for the two functions, the display screen (EC), a clock and a calendar (HC) which can be displayed and provided with programmable alarms, the battery (PI), the box (BO) housed in a drawer (TI) which makes the device compact, resistant and waterproof when closed with the bolt (VE). A loop (PA) on the back of the drawer (TI) allows you to strap the device to yourself,

  or to plug it into a support, for example: a vehicle dashboard. According to the main description on pages 1/3 and 2/3, any activation of an alert triggers a radio signal

  (Sl) coded by the coder (CD) which conceals the nature of the danger encountered, by the user (X or Y) and allows a research station (20) to locate the device and to warn the emergency services (30). The device (TBS) operates on two frequencies and uses several communication channels which are: a constellation of localization satellites (11,12), which picks up the coded radio signals (Sl, S2) transmitted by the device (TBS) and retransmits them to a research station (20). A second satellite (40) is responsible for the telephone communications (C1, C2, C3). The station (20) processes the coded radio signal (Si or S2) which gives the location of the device (TBS), the nature of the danger and the identity of the subscriber; in the case of an alert, it transmits the information to the emergency services (30) by the channel (Cl) .35 A radio receiver (RT) and a radio transmitter (ET) for the radiotelephone operate on one frequency and a second

  radio transmitter (EB) for the beacon operates on another frequency.

  The main components of the telephone are: a radio receiver (RT), a digital-to-analog converter (CE) and an input earpiece (HP); a microphone (MI), an analog-digital converter (CS) and an output radio transmitter (ET) connected to the antenna (AN); specific keyboard keys (CL). the main components of the beacon are: alert keys "SAMU" (SA), "Police" (PL), "Fireman" (PP) and the key (PT) on the keyboard (CL), which can be activated from 10 drawer (TI) closed, two detectors, one of shock (C) with its adjustment potentiometer (P), the other of drowning (E) corresponding with the outside of the case (BO) by an opening (OE) , a delay element (RE) for triggering automatic transmissions in the event of an accident, an encoder (CD) for radio signals, an element (SE) spacing the transmissions in sequences (example every 30 seconds), a radio transmitter (EB) connected to the antenna (AN), the decoding circuit (DE). Device operating mode (TBS): When an alert is triggered, the control unit (MP) 20 transmits the signal to the coder (CD) which generates a specific radio coded signal (S1) emitted by the transmitter of the beacon ( EB) and the antenna (AN). In the case of two successive automatic detections, the second detection will cancel the first. When the drawer (TI) is closed, the device (TBS) is hung, the functions are on standby if they have not been cut. When the phone rings, opening the drawer (TI)

  deploys the microphone (MI), picks up the device and turns off the horn. The telephone operates in a conventional mode, with priority to the beacon for the 30 triggers by the detectors (C, E). The users W and Z call each other by the channel (C3) page 2/3.

  In manual mode, it is sufficient to activate one of the warning keys twice, accompanied by an audible "beep", which each have a coded radio signal of specific danger (S1). The user (X) 35 obtains his only location by twice activating the "dot" key (PT) on the keyboard (CL) which triggers the specific coded radio signal (S2). Once the station (20) has processed

  the signal, it sends by telephone and the channel (C2) the location to the device (TBS).

  11-1 4 In automatic mode, let's take the example of a car accident that occurs to the user (Y). The shock, which exceeds the potentiometer setting threshold (P), is detected by the shock detector (C) which triggers a coded radio signal (Sl) 5 after a delay time generated by the element (RE) during which the user (Y) warned by an alarm (SO, LA), can cancel the transmission order with the "CLEAR" (CR) key on the keyboard (CL). The station (20) receives and processes the signal (S1) from the satellites (11, 12), communicates the identity of the subscriber, 10 the nature and location of the accident by telephone to the emergency service (30), via the satellite (40) and the channel (Cl). The emission by a station of a specific coded radio signal, recognized by the decoding circuit (DE), automatically activates the emission of the remote beacon if no function is not already activated. Other device architectures (TBS) page 3/3: According to the architecture in figure 6, the device (TBS) operates on a single frequency, with a radio receiver (R), a radio transmitter (E) common to the telephone and the tag. The

  mode of use is similar to that of the main description on page 1/3. Telephone broadcasts and

  beacon are managed by the command block (MP). According to the architecture in FIG. 7, the device (TBS) operates on a single frequency, with a radio transmitter (E) and a radio receiver (R) common to the telephone and to the beacon, the decoder (DC) sends the telephone signal to the earpiece (HP) and the location signals on the computer (CC), which calculates its location, which can be displayed on the screen (EC) if the (PT) key has been pressed, or transmitted30 with one of the messages distress information contained in the memory (ME) by the transmitter (E) of the telephone at a

  emergency (30), if an alert has been triggered. The mode of use is similar to that of the architecture in figure 8 below.

  According to the architecture in FIG. 8, the device (TBS) has a radio receiver (RB) which picks up on a frequency the radio signals of a constellation of location satellites and directly processes the information with its decoding elements (DC) and (CC) which give its location, Iri which can be displayed on screen (EC) if the (PT) key has been

  activated, or transmitted by telephone to an emergency station (30), with one of the specific danger distress messages contained in the memory (ME), if an alert has been triggered.

  The radio receiver (RT) and radio transmitter (ET) of the radiotelephone operate on another frequency. According to the architecture in Figure 10, the device (TBS) has the elements of the architectures in Figures 9 and 8 in redundancy, managed by the control unit (MP). 10 According to the architecture in Figure 11, the device (TBS) has the elements architectures Figures 6 and 8 in redundancy, managed by the control unit (MP). According to the architectures in figures 7,8,10,11, the remote triggering of the beacon by a research station can be carried out by a specific coded radio transmission, recognized by the decoder (DC), the latter is redundant with the

  decoding circuit (DE) for architectures 10 and 11, and optionally for architectures 7 and 8.
