Abstract

1293123 Lasers S L BOSTROM 7 Jan 1970 [7 Jan 1969] 879/70 Heading H1C [Also in Division E2] Apparatus for actuating a security device comprises a key and a receiver including a plurality of photo-electric transducers and electrical circuitry and the key comprising means which, when the key is in use, cause radiation to reach the transducers with the result that a predetermined pattern of electric signals from the transducers is applied to the electrical circuitry which then causes the receiver to produce a security device actuating signal whilst, with no key or a different key being used, the actuating signal is not produced. A key N when inserted in a keyhole completes, at K, a circuit for a polarized laser beam LS which passes through a bore 11 of the key. The bore 11 connects with a series of aligned cross bores 100, 101 to 108, 109 and these cross bores align respectively with bores 200- 209 in the well of the keyhole. Part of the laser beam is deflected along one pair of cross bores 100, 101 by surfaces 12, 13 of prisms and the beam passes through a colour filter F, and a polarization filter P1 in each cross bore. The bore 10 of the key decreases in diameter between each pair of aligned keyhole bores each of which has a filter to allow a beam of a different colour through and a polarization filter. Thus the key and keyhole transmit to the receiver a number of beams of different wavelength. Each beam actuates a photoelectric cell PH1 to PH5 respectively, an amplifier N51 to NV5 and a flip-flop FF1 to FF5. The flip-flops control a gate provided with a number of inputs U1 to U5, Figs. 3 and 4 (not shown), to actuate an electromagnetically operated bolt. Two of the polarization filters in the key are variable by a dial IS on the key handle. The dial may be combined with a combination lock having a plurality of rotatable barrels with numerical indices which have to be set in a predetermined manner. The key may be completely transparent and portions may be made from material having different optical properties. The key may include solar cells.
