Abstract

1435415 Radio signalling TESLA NARODNI PODNIK 18 March 1974 11845/74 Heading H4L In an emergency call system for vehicles on a highway, each vehicle carries a radio transmitter with means for selecting one of a plurality of predetermined signals, indicating, for example, accident or vehicle need, a plurality of radio receivers are spaced at predetermined distances along the highway for receiving signals from said transmitters and each include a code signal generator responsive to the received signals which produces an output code signal identifying the particular radio receiver and thus its position and containing the information from the vehicle transmitter and means are provided for transmitting the code signal by radio or landline to a remotely located indicating means. The signals may be combined in multiplex with those of other roadside receivers. The vehicle transmitter may be operated by push-buttons which, to prevent abuse, have to be reset by a special operator or by the use of special means. The indicating means includes a plurality of memory circuits and if a further call is received the existing one is transferred from one memory to the next.
