Abstract

1427920 Inductive signalling; transponders PLESSEY CO Ltd 6 June 1973 [28 June 1972] 30231/72 Addition to 1187130 Headings H4U and H4L The system for the identification of vehicles disclosed in the parent Specification 1,187,130 is arranged to be used for the identification of articles other than vehicles. In one arrangement the transponder is in the form of a "key" unit which when placed in the vicinity of a door incorporating interrogation means, opens the door if a correct coded response is obtained. The "key" may be in the form of a personal identification card which may be interrogated, by apparatus linked to a computer. The identification of baggage or freight and the use of the transponder as a beacon alongside a track or road are referred to.
