ABSTRACT:
The invention relates to a device and method for evaluating a useful signal U(t) originating from a proximity sensor. The device comprises a first recognition means (17) which changes the switching state thereof when the value (U1(t)) of a first signal produced from the useful signal exceeds a first limit value that characterizes the proximity of an object. In addition, a second recognition means (34) is provided which changes the switching state thereof from a first to a second state when the value (U(t)) of the useful signal exceeds a second limit value that characterizes the removal of an object. A decision means (32), which is connected to the first recognition means (17) and to the second recognition means (34), changes its switching state when the first recognition means (17) changes the switching state thereof from its first to a second switching state, and the second recognition means does not change the switching state thereof during a predetermined first time span (Δt1) after the switching state of the first recognition means is changed.
