The bus system is divided into segments (A,B,C) each having a predetermined number of consumers (138a,138b,138c) which are respectively associated with current supply units (16a,16b,16c), and having a first current supply line (46a) and a second current su...

A light transmitter (12) transmits light signal (24) into detection zone (22). A light receiver (14) has several receiver elements to receive light (25,28,30) diffusely and/or specularly reflected from detection zone. A reception optics (18) between detect...

The sensor (10) has a light emitter (12) and a light receiver (36) imaging an object, and a distance measuring unit (42) determining distance between the sensor and the object. Magnification of the object is corrected by a scale correcting unit (44) in dep...

The laser scanner (10) has a rotary deflecting unit (18) for periodically deflecting the transmission light beam (16) in the monitoring area. Based on the angle position of the defecting unit, an angle encoding unit (30) generates an angular position signa...

The laser scanner (10) has a light transmitter (12) for emitting a transmitted light beam (16), a rotating deflector (18) for periodic deflection of the transmitted light beam into the monitoring area (20), a light receiver (26) for generating a received s...

The device use phase displacement of reflected light of a modulated transmission light beam. It has a light transmitter (21) for transmitting modulated light, a high frequency generator (11) for generating a high frequency control signal and a modulation c...
