Abstract
The invention relates to a system and a method with at least one presence detector, wherein the presence detector has a radio transmitter. The system further comprises at least one radio receiver that is constructed in such a manner as to receive and evaluate signals of the presence detector transmitted via radio. The radio receiver further comprises at least one device that acts on downstream units as a function of the evaluation result.

39. A system comprising:
-
a presence detector powered by energy available from a surrounding environment, the presence detector comprising a presence sensor and a first radio transmitter, wherein said presence detector is constructed to send at least a first predeterminable signal by said first radio transmitter, and wherein said presence sensor is coupled to said first radio transmitter, and said presence sensor triggers the transmitting of said first predeterminable signal in response to a sensed presence; a terminal for an electrical load; a radio receiver, which is constructed to couple said terminal by a first switching element to an electrical energy source in response to receiving the first predeterminable signal, and which is constructed to decouple said terminal by said first switching element from the electrical energy source after a time point of a last reception of said first predeterminable signal; a wireless switch constructed to transmit, wirelessly and energy-autonomously, at least one of the first predeterminable signal and a second predeterminable signal by a second radio transmitter, wherein the wireless switch comprises an actuating element that is coupled to an electromechanical energy converter in such a way that a mechanical force exerted on said actuating element is converted at said energy converter into electrical energy which is conducted to said second radio transmitter. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)

53. A method for use with a presence detector comprising:
-
transmitting by a presence detector a first predeterminable signal after a sensed presence; receiving the first predeterminable signal; coupling a terminal for an electrical load by a radio receiver to an electrical energy source by a switching element in response to receiving the first predeterminable signal; after lapse of a predetermined time period following the time of a last reception of the first predeterminable signal, decoupling the terminal by the switching element from the electrical energy source; supplying energy for operating the presence detector and its components from energy available from the environment; providing one of the first predeterminable signal and a second predeterminable signal energy-autonomously by a wireless switch; and powering the wireless switch by converting mechanical force exerted on an actuating element included in the wireless switch into electrical energy.
