A demodulator of an evaluating unit for a device for detecting objects derives a useful signal from a supplied input signal with the aid of a carrier signal. The demodulator further derives a test signal with the aid of a modulated carrier signal. An evaluator detects as a function of the useful signal whether an object is being detected and, as a function of the test signal the functionality of the device.

EVALUATING UNIT FOR A DEVICE FOR DETECTING OBJECTS, IN PARTICULAR FOR MONITORING THE INTERIOR OF A MOTOR VEHICLE, AS WELL AS A DEVICE FOR DETECTING OBJECTS HAVING SUCH AN EVALUATING UNIT AND A METHOD FOR CONTROLLING SUCH A DEVICE

An apparatus for withdrawing compressed fodder or similar agricultural material from a pile has an engaging tool which is mounted on a cantilever arm arrangement. This arrangement is capable of reaching over a quantity of fodder to be withdrawn and engaging behind the quantity from above so that the remainder of the material will not be loosened. The engaging tool shifts the quantity of fodder into a receptacle which is mounted on a common support with the cantilever arm arrangement, the support being adapted to be mounted on a tractor. Hydraulic cylinder-and-piston units connected to the hydraulic system of the tractor are used for moving the engaging tool into and from the receptacle.
