Living being e.g. person, counting and living being`s passage direction determining device for e.g. building, has unit determining number of living beings by analyzing signal of sensor, and direction by analyzing signals of sensor and cell

摘要

#CMT# #/CMT# The device (500) has a pyro-electric sensor (502) for delivering an electric signal representing passage of a living being (114) in front of the sensor. A pyro-electric cell (102) has detection windows (104, 106), and delivers another electric signal representing the passage of the living being in front of the pyro-electric cell. A processing unit determines the number of living beings passing in front of the device by analyzing the former signal, and the passage direction of the living beings by analyzing the signals. #CMT#USE : #/CMT# Used for counting number of living beings and determining passage direction of the living beings (claimed) such as person, on a carriageway or in a building. #CMT#ADVANTAGE : #/CMT# The processing unit permits to count the number of living beings passing in front of the device and to determine the passage direction of the living beings in a precise manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a living being counting and living being`s passage direction determining device. 102 : Pyro-electric cell 104, 106 : Detection windows 114 : Living being 500 : Living being counting and living being`s passage direction determining device 502 : Pyro-electric sensor.
