Abstract:
A device for counting and determining the direction of passage of living beings. A first cell delivers an electrical signal representing the passage of a living being. A second pryoelectric cell delivers a second electrical signal. A processing unit analyzes the signals and determines the number of living beings moving past and their direction of movement.
