Abstract

1529789 Photoelectric security system CHUBB & SONS LOCK AND SAFE CO Ltd 17 Nov 1975 [16 Aug 1974] 36106/74 Heading E2A A security system comprises a first unit actuable by light to emit electromagnetic radiation and a second unit which operates a release device for a door, &c on receipt of the electromagnetic radiation. As shown, a spring loaded locking bolt 2 is withdrawn by a solenoid 3 controlled by an electronic unit 4 and power supply 5, all carried on a door 1. A lamp 6 on the door is powered by unit 5 to emit light for receipt by the first unit e.g. a finger ring 9, coil 10 of which emits electromagnetic radiation which is received by coil 8 of the second unit to operate the solenoid. Unit 9, Fig. 3, comprises a photovoltaic device 11 with binary coding and oscillator circuits 12, 13. The second unit 4 has a receiver circuit 14, a binary decoding circuit 15 to check conformity with the pre-set binary code and if so, to energise solenoid 3. Unit 9 may be carried in a finger or ear ring, watch strap, cuff link, button, pen, pencil, &c. In the modification of Fig. 4, a further light source 16 e.g. a gallium arsenide diode, stimulated by a pulsing circuit 17 is included. The pulses of infra-red light are received by sensor 18 and supplied to a decoding circuit 19 via amplifier 20. The circuit 19 may include a time delay facility, and unit 4 may have a limitation on the rate of receipt and decoding of pulses. The same key unit may release a plurality of locks or a plurality of key units of the same or differing codings may be needed to operate one lock.
