Abstract

1,213,485. Track apparatus. PLESSEY CO. Ltd. 2 Dec., 1968 [9 Dec., 1967], No. 56090/67. Heading B7N. [Also in Division H4] In an interrogator-responder system for the identification of vehicles e.g. railway wagons, in which each vehicle carries a transponder which transmits a coded identification signal, the transponder is powered by an energy-storage element, e.g. a capacitor which is charged over a relatively long period prior to the interrogation while the vehicle passes an inductively coupled power transmitting means extending along the path of the vehicle. As shown an oscillator 2 supplies the power via an aerial 3 to charge a capacitor in the transponder 5 as the vehicle 4 moves from A to B. When the vehicle reaches section D a switching signal is transmitted from the interrogator 11 via aerial 9 to connect the message-generator unit of the transponder to the charged capacitor, the resulting identification signal being received by aerial 10 at the interrogator.
