Patent ID: 8819992

Claim:
A monitoring apparatus for monitoring movement of a movement element which is mounted such that the movement element can be pivoted about a rotation axis and driven by means of a drive, wherein the movement element can be pivoted between an open and a closed state of an opening, the movement element comprising a pivoting door mounted such that the movement element can rotate about a rotation axis by means of a door hinge and can be moved about the rotation axis by means of a motor, wherein the monitoring apparatus has a sensor for detecting an object and for monitoring a spatial angle having an origin in a region of the rotation axis, wherein the sensor can be fitted in the region of the rotation axis and comprises a transmitter and a receiver for transmitting and receiving electromagnetic detection radiation within the spatial angle, and wherein the sensor is designed to emit detection signals generated by the receiver when electromagnetic radiation is detected, wherein the monitoring apparatus comprises an evaluation unit which evaluates the detection signals depending on an angular position of the detected radiation in the spatial angle and determines at least one of whether the object has been detected and a position of the object, wherein the evaluation unit distinguishes between the movement element and the object depending on a current angular position of the movement element.
