Document Type and Number:
WIPO Patent Application WO2003016941
Kind Code:
A3
Abstract:
The invention relates to a monitoring device using echo signals. Said device comprises a plurality of transceiver units (1-1,...1-4), for transmitting signals and receiving the echoes reflected from an external object, as well as an evaluation unit (8), for evaluating the distance between the monitoring device and the external object by means of the received echoes. Said device is characterized in that it has an operating state for calculating the relative position between said transceiver units by means of the reflected echoes.
