A presence analysis system for objects carried by a user has a
signal-transmitter provided on the object to be observed in terms of its
presence for transmitting an object or signal-transmitter specific signal
and a receiver for receiving signals including the object or
signal-transmitter specific signal. A capacitative link formed by the
person or clothing of the person conducts the signal from the transmitter
to the receiver. An analysis unit coupled with the receiver generates an
output signal indicating the presence or absence of the object by
analysis of the signals received.
