Patent number: 5187688Abstract: A passage is periodically scanned by a plurality of ultrasonic transmitters/receivers (sensors) arranged on the ceiling of the passage in two lines to calculate the height of an object to be measured to each sensor and the presence or absence of the measured object(s), moving direction(s) thereof, and the number thereof are reckoned from changes in sensed height and sensing time for each sensor induced by passing an object to be measured through the passage, and the position and a change in position with time of each sensor which senses the measured object concerned to count the number of passers-by in each moving direction. The presence or absence of the object to be measured and the number to be counted are decided in accordance with changes in sensed position and sensed height and the interrelation thereof, so that the number of sensors can be reduced and the number of passers-by can be counted at a high accuracy even when a plurality of persons pass under the sensors in a group.Type: GrantFiled: April 6, 1992Date of Patent: February 16, 1993Assignee: NCR CorporationInventor: Makoto Saruta
