#CMT# #/CMT# The method involves flexibly connecting transmitters (1) and receivers (2) with one another. A signal reception is interrupted besides beam interruption by beam deflection based on the flexibility of the connection. Positions, levels, areas or objects are determined or monitored contactlessly or by contact with an optical combination sensor. Hazardous objects outside of a transceiver area are recognized, and the optical combination is automatically aligned within a defined area. #CMT#USE : #/CMT# Used in a building automation and in a sheet reversing device, for simultaneously determining and monitoring positions, levels, areas or objects for monitoring a door and window, and for turning individual pages put down in a folder. #CMT#ADVANTAGE : #/CMT# The method determines and monitors positions, levels, areas or objects in an inexpensive, reliable, accurate and efficient manner even over larger and changing distances. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sheet reversing device for turning individual pages put down in a folder. `(Drawing includes non-English language text)` 1 : Transmitters 2 : Receivers 3 : Spring arm 10 : Receiver barrier. |
