Title (EN) DUAL RF/IR COMMUNICATION DEVICE AND METHOD OF USE THEREOF
(FR) DISPOSITIF DE COMMUNICATION DOUBLE RF/IR ET SON PROCEDE D'UTILISATION
Abstract:
(EN) A communication device (20, 21, 22, 23) including an RF transmitter (58, 153) mounted in conjunction with an IR transmitter (42, 56, 151) allowing data to be transmitted by RF as well as by IR. Such a device may be a portable badge worn by moving personnel to transmit IR and RF signals to one of a plurality of second devices each being a fixed reader having an IR and RF receiver, and typically being mounted in a respective enclosed space, such as a room. In use, IR transmissions from the portable device are detected by the IR receiver (72) of the reader (14, 15, 16) in the same room (11, 12, 13) and thus provide an immediate identification of the room (or enclosed space) wherein the portable device is located. On the other hand, if the IR transmitter in the portable device is concealed or for any other reason is not within line-of-sight of the reader in its immediate proximity, then the RF signal transmitted by the RF transmitter in the portable device is detected by the RF receiver (81) in the reader (17), thereby allowing tracking of the portable device in either eventuality.
(FR) La présente invention concerne un dispositif de communication (20, 21, 22, 23) comprenant un émetteur RF (58, 153) monté conjointement avec un émetteur IR (42, 56, 151), permettant la transmission de données aussi bien par RF que par IR. Un dispositif de ce type peut être un badge portatif porté par le personnel en déplacement, servant à émettre des signaux RF et IR à l'un des seconds dispositifs correspondant chacun à un lecteur fixe présentant un récepteur IR et RF et étant en général chacun monté à l'intérieur d'un espace fermé respectif tel qu'une pièce. Lors du fonctionnement, les émissions IR provenant du dispositif portatif sont détectées par le récepteur IR (72) du lecteur (14, 15, 16) se trouvant dans la même pièce (11, 12, 13), ce qui permet une identification immédiate de la pièce (ou espace fermé) dans lequel le dispositif portatif se trouve. D'autre part, si l'émetteur IR du dispositif portatif est occulté ou, pour une raison quelconque, ne se trouve pas à portée optique du lecteur dans son voisinage immédiat, le signal RF émis par l'émetteur RF du dispositif portatif est alors détecté par le récepteur RF (81) du lecteur (17), ce qui permet dans tous les cas d'effectuer le suivi du parcours du dispositif portatif.
