<p>PCT No. PCT/DK93/00253 Sec. 371 Date Feb. 6, 1995 Sec. 102(e) Date Feb. 6, 1995 PCT Filed Aug. 5, 1992 PCT Pub. No. WO94/03690 PCT Pub. Date Feb. 17, 1994A lock system comprising an electromechanical lock and code generator, and an electronic code lock, which is connected to a code transportation medium. The electronic lock and code generator is a system, where the code medium includes both a mechanical and an electrical code, which both must be present with the correct code before the code transport transmitter can be activated. The transmission of the code takes place within a short time interval and at an individual transmission rate, and a timed blocking is built-in in case of an incorrect optical code, and a circuit counteracting voltage manipulation is built-in. The code transportation medium is electrical or optical. The electronic code lock is a system, where the correct code must be received twice successively. A built-in timed blocking of the analysis of the code is activated if an incorrect code is received, or if the code has not been received at the correct transmission rate, and an electronic circuit counteracting voltage manipulation is built-in.</p> |
