Abstract

1518504 Electronic stop-clock NATIONAL RESEARCH DEVELOPMENT CORP 10 Oct 1975 [16 July 1974] 31464/74 Heading G3T [Also in Division G4] For timing visual tasks a pseudorandom sequence of alphanumeric digits at a constant rate is presented to the viewer who records the digits at beginning and end of the task enabling the time taken to be deduced from the known sequence. In timing the response of a car driver the digits are presented by a display on the car bonnet, Fig. 2 (not shown); the driver reads out the digits until the start of the task and then resumes at the end, this being recorded by a tape recorder and the missing digits determining the time taken. The timing apparatus, Fig. 1, comprises an oscilator 1, a divider giving various outputs allowing the display rate to be changed and a shift register 4 with variable feedback logic 5 for selecting the sequence. At each step of the shift register 4 a comparator 6 holds open a gate 9 to advance a counter 11 until it is in the same state as the register. The pulses passed by gate 9 at each step are also counted by a counter 12 which operates a display 14. A further counter 7 counts the number of times the gate 9 is opened and indicates the number of sequences which have been displayed.
