ABSTRACT:
An interface logic circuit for supplying direction of passage data to a data utilization apparatus from a moving-object sensor which generates three recognition signals indicative of intrusion of an object into the left end, center, and right end, respectively, of a sensing space adjacent the sensor, comprising directional logic means for generating left-to-right and right-to-left object passage signals in response to the recognition signal sequences left-center-right and right-center-left, respectively, independently of overlap between the recognition signals or duration of the individual signals, and inhibit logic means for inhibiting generation of both object passage signals for all other recognition signal occurrence sequences.
