Abstract (en)
[origin: EP0598398A2] In radio and TV receivers, a useful information signal with a data word is recovered and radiated via the loudspeaker/loudspeakers, the data word being picked up by an ultrasonic microphone (7) arranged on a digital wrist-watch and being processed further by electronic integrated circuits, values such as data word (17) and transmitting time being stored in a memory (13). These values are transmitted to a central computer by means of a telephone line via an adapter and a modem (15). The detecting device only operates as such when it is also located directly at and, respectively, on a test person. It is activated when a temperature detection element is heated by skin contact. <IMAGE>
