Title: Data change detector
IPC: G01G23/18
Filed: 1971-10-26
Abstract: 1328739 Selective signalling RELIANCE ELECTRIC CO 26 Oct 1971 [7 Dec 1970] 49760/71 Heading G4H A data-change detector has primary and secondary storage devices, the latter being loaded from the former when lack of coincidence between them is sensed due to data-change, and also (under control of a counter) when coincidence is sensed a predetermined number of consecutive times. The tenths and hundredths orders of the output of a digital voltmeter, computing weighing scale or shaft encoder, are set in binary-coded-decimal form into primary latches 10, 13. On occurrence of a "check motion" signal, i.e. periodically such as at the completion of each sensing cycle of the input device, the numbers in the primary latches 10, 13 are preset into up-down counters 12, 15, and a counter 22 is reset. Clock pulses from a clock 24 are passed via AND 28 to increment counter 22 and also via AND 29 to increment counter 15, with carries into counter 12, incrementing being stopped when counter 22 coincides 31 with a tolerance value set up on switches 32, a flip-flop 25 also being set then. If, during the incrementing, counters 12, 15 agree with secondary latches 11, 14, coincidence units 16, 17 control AND 8 to set a flip-flop 23. Whether flip-flop 23 is set or not, the setting of flip-flop 25 referred to above resets counter 22 and presets the numbers in latches 10, 13 into counters 12, 15 again. Clock pulses from clock 24 are passed via AND 28 again to increment counter 22 and also via AND 30 to decrement counter 15, with borrows from counter 12, until counter 22 coincides 31 with the tolerance value on switches 32. If during the decrementing, counters 12, 15 agree with secondary latches 11, 14, flip-flop 23 is set by AND 8. Thus flip-flop 23 will be set if the value in primary latches 10, 13 is within plus and minus the tolerance (switches 32) of the value in secondary latches 11, 14. If flip-flop 23 was not set, a counter 38 is reset, whereas if flipflop 23 was set, counter 38 is incremented. If a count (at 38) selected by switches 40 is reached, AND 39 produces a "no motion" signal which (via inverter 41) inhibits further incrementing of counter 38 (the "no motion" signal will of course be removed, together with the inhibition, if the counter 38 is reset as mentioned above). Whenever the counter 38 is reset, and in addition if the "no motion" signal is present, OR 37 loads the secondary latches 11, 14, from the primary latches 10, 13.
