Description:
A portable modular system for persons with impaired hearing and impaired vision, which picks up signals from the surroundings and, when necessary, delivers alarm signals to auxiliary facilities, such as an alarm centre, for instance. The system includes a wristworn receiver (1) for receiving digital radio signals, and a sound recognizing unit (3) adapted to receive acoustic signals, for instance signals from a telephone (6), a doorbell (7), a fire alarm (8) and a public radio receiver (9) having alarm signal receiving means (RDS - Radio Data System). In response to these acoustic signals, the unit (3) delivers digital radio signals to the wristworn receiver (1), which includes mechanical time indicating means (31), optically readable means presented on a dial (2) in the form of symbols (52, 53, 54, 55, 56, 57) corresponding to respective acoustic signals. The wristworn receiver (1) incorporates a vibrator (43, 45) which produces vibrotactile signals having characteristics that correspond to the acoustic signals. The system also includes a microphone-based child minding unit (24, 25, 26) which when the noise level of a child's cry exceeds a predetermined sound level and is of long duration functions to send a digital radio signal to the wristworn receiver (1). La présente invention concerne un système modulaire portatif destiné aux personnes souffrant d'un handicap de l'audition et de la vision. En l'occurrence, ce système capte des signaux produits par l'environnement et, en cas de besoin, fournit des signaux d'alarme à des installations auxiliaires, tels que par exemple une centrale d'alarme. Le système se compose d'un récepteur de poignet (1) permettant la réception de signaux numériques radio, et d'une unité de reconnaissance sonore (3) conçue pour la réception de signaux acoustiques, par exemple, une sonnerie de téléphone (6), une sonnette de porte (7), un avertisseur d'incendie (8) et un récepteur radio grand public (9) équipé d'un dispositif de réception de signal d'alarme du type RDS (Radio-Data System). En réaction à ces signaux acoustiques, l'unité (3) fournit des signaux radio numériques au récepteur de poignet (1) qui est pourvu d'organes mécaniques d'indication de l'heure (31), d'organes de lecture optique se présentant sur un cadran (2) sous forme de symboles (52, 53, 54, 55, 56, 57) correspondant chacun à un signal acoustique. Le récepteur de poignet (1) comprend un vibreur (43, 45) qui produit des signaux tactiles vibratoires présentant des caractéristiques correspondant aux signaux acoustiques. Le système comporte également une unité de surveillance d'enfant (24, 25, 26) fondé sur l'utilisation d'un microphone qui envoie un signal radio numérique au récepteur de poignet (1) lorsque le niveau sonore des pleurs de l'enfant dépasse un niveau prédéfini et dure assez longtemps.
