Abstract

1414119 Inductive sigriallying LEWIS SECURITY SYSTEMS Ltd 7 Nov 1972 [8 Nov 1971 16 May 1972] 51724/71 and 22898/72 Heading H4U [Also in Divisions G4 and E2] A system for controlling the access of authorized and unauthorized persons to particular areas comprises a portable token 20 capable of transmitting oscillations at a predetermined frequency, a control unit 16 which detects whether the oscillations are being picked up at a certain location and a sensor 15 responsive to the presence of a person. An authorized person carries the token 20 which generates two distinct radio frequency signals, the signals being detected by an inductive loop arrangement 18 consisting of three coils positioned orthogonally in the walls and ceiling of a corridor adjacent a door 11. The signals from the coils are phase shifted and combined in adders to ensure that they cannot cancel each other out. The sensor 15, which may be an infra-red, photoelectric, acoustic, microwave or capacitive device, or a weight operated switch or a door handle switch supplies a signal to the control unit 16 to initiate a detection cycle. A local oscillator and mixers in the control unit detect the beat frequency between the token and local oscillator frequencies and beat frequency pulses are passed via gates opened for an interval of one fifth of a second to the "up" input of a counter. During a second one fifth of a second interval the frequency of the local oscillator is increased and the beat frequency pulses are fed via further gates to the "down" input of the counter. If both of the token frequencies have been detected the nett count in the counter has a predetermined value and a logic circuit connected to the counter output enables the door 11 to be opened by a signal on a line 17. A display 31 indicates whether the door has been approached and if the person was accepted or rejected, an alarm being operated in the latter case. Sockets 32 are provided for recharging the batteries of the tokens.
