ABSTRACT:
An inductively-coupled signalling system having multiple waveforms, for exchanging information between a vehicle and a storage facility, said system including a safety, separable signal-coupling device comprising a signal-transmitting coil carried in a housing and disposed at an accessible location at or on the vehicle, and a signal-receiving coil carried by a cable having a second housing, said cable leading to a signal-receiving and deciphering means located at the storage facility. The two housings of the coupling device are adapted for juxtaposition to each other so as to locate the coils thereof in inductive relation. A magnetic keeper part on one of the housings and a magnet part on the other housing releasably retain the housings in operative relation when the coupling device is in use. The receiving coil housing constitutes almost a complete magnetic shield for the receiving coil so as to minimize stray pick-up of spurious signals. In addition, the magnet and keeper parts are force-release responsive so as to permit virtually instantaneous non-destructive separation of the housings in the event that the vehicle is inadvertently driven off while the housings are still operatively coupled.
