ABSTRACT:
A counting apparatus including a sensor surface having a plurality of zone locations with pressure actuated switches which produce a contact event signal corresponding to the zone location when an object traveling across the sensor surface contacts the zone location, a microprocessor connected to the pressure actuated switches having software for analyzing the contact event signals according to predetermined temporal and spatial criteria stored in the memory of the microprocessor, the microprocessor producing an increment signal when a sequence of contact event signals satisfies one set of criteria related to "in" counts and a second increment signal when a sequence satisfies another set of criteria related to "out" counts, and a counter with a two-channel count register which increments one channel in response to an "in" increment signal and increments a second channel in response to an "out" increment signal.
