Patent GB-2110855-A (GB)
Title: Computer-based interlocking system
Inventor: BROWN CHRISTOPHER ROBERT
IPC: G05B9/03
Filed: 1982-10-07
Abstract: An interlocking system comprising a plurality, e.g., three, of parallel sub-systems operating asynchronously to produce identical replicated outputs which are mutually compared to determine the correct output and disqualifying a minority output thereby ensuring high system integrity. Each sub-system includes a similar arrangement for computing the difference between all possible pairs of sub-systems. Comparison of these results with a reference table of all possible difference results and then comparison of the difference equations yields a common factor which is the sub-system producing the error. Action can then be taken to disqualify its output, e.g., by switching-off its power supply. A final output is taken, preferably from one sub-system, with a second as standby. To accomodate asynchronous running, a final output is only acted upon if it is repeated in a succeeding output cycle thus permitting opportunity to disqualify the preferred output if it is judged in error by the other sub-systems and to replace it by the standby.

Title: Wall switch timing circuit
Inventor: WEBER LAWRENCE W
IPC: H03K17/292
Filed: 1983-12-22
Abstract: An electronic timing device opens an electrical circuit whenever the circuit, e.g., a lighting circuit, has been left closed accidentally. The device is wired in series with an existing wall switch 13 and the load 12 which it controls. Whenever the existing switch 13 is turned on, a load sensing circuit senses the flow of current and triggers a timing circuit. The timing circuit may be preset to some arbitrary time period. At the expiration of the time period, the timing circuit opens a switch circuit 1 to disconnect the load. The timer assembly is sufficiently compact that it fits within a modified switch plate having a slight recessed area surrounding the switch lever opening (Figs. 3 to 5). Optionally, when the timer times out, the switch 1 may be intermittently closed to give a flashing warning for a predetermined period before the switch 1 is finally opened continuously. An audible warning may alternatively be given. The device may be connected in parallel, rather than series, with the existing switch 13 to function as a turn-off delay. <IMAGE>
