Title:
音波によって対象物の位置を監視する装置
Document Type and Number:
Japanese Patent JP7043345
Kind Code:
B2
Abstract:
A device for monitoring the local orientation or position of an object by sound waves, with a sensor part positioned at a distance from the object with at least one sound wave emitter, at least one sound wave receiver, and a computing unit. The computing unit controls the at sound wave emitter and the sound wave receiver and determines the distance between the sensor part and the object, based on the echoes of a sound wave emitted by the sound wave emitter in the direction of the object. An identification reflector separate from the sensor part comprises a three-dimensional pattern. The sensor part has an array of sound wave receivers and sound wave emitters, wherein for identifying the identification reflector and for measuring the distance between the sensor part and the identification reflector, a plurality of echoes between different emitter/receiver-combinations is evaluated.
