Abstract: Disclosed is a radio control device which is used for issuing commands in a wireless manner to a remote controlled apparatus and in which an allocation mode can be run before said radio control device is operated. The inventive radio control device comprises a transmitter/receiver unit, a control mechanism, and at least one antenna. Once the user has triggered the allocation mode, the radio range of the remote control device is lowered such that communication can be established only with an apparatus that is located in the immediate vicinity of the remote control device and returning to the standard range is possible only once the allocation process has been completed.

Abstract: The invention relates to a remote control for issuing commands to a remote-controlled device in a wireless manner. In said remote control, an assignment mode can run prior to start-up. The remote control also comprises a rechargeable battery for supplying power. The remote-controlled device is equipped with a docking point for the remote control, to which the latter can be temporarily fixed.

Abstract: The tire comprises a radially inner carcass (1), a base layer (2) which is applied to said carcass radially, externally; a profile comprising numerous profile elements (3, 4, 5) applied radially, externally to said base layer (2); and a sensor (6) which is located in the base layer (2) and associated with one profile element (5) selected from said profile elements (3, 4, 5) and which is used to determine a maximum force exerted on said selected profile element (5). The selected profile element (5) is mechanically separate from all of the other profile elements (3, 4). The method for determining a wear value for a tire of this type that turns and rolls on a base surface (10) provides that the maximum force is measured while the tire is rolling and that the wear value is determined from this maximum force.

Abstract: A method, as well as an associated sensor device and use of such method, for identifying a system state of a technical system (7) by a sensor device with an antenna element (1; 10) for receiving and transmitting radio signals (13; 14) to detect and communicate the system state. The transmission behavior of the antenna element is determined by controlling at least one load impedance (8) of the antenna element. The load impedance of the antenna element is controlled by a physical signal (6).

Abstract: A wear monitor suitable in particular for monitoring the wear and tear of rider rings (7) on the pistons (5) of horizontally operating reciprocating compressors presents a sensor (9) that monitors the thickness of the rider ring (7) at least indirectly, is arranged in the area of the rider ring (7) in such a way as to move together with it and can be interrogated without contact via a motionless interrogation unit (16), which communicates with an evaluation unit (18). The sensor (9) preferably presents a passive surface acoustic wave element (23), whose electromagnetic reflection behavior depends on the thickness of the rider ring (7) consequent upon the degree of wear and tear thereof and which communicates with a sensor antenna (19) moving together with it, while the interrogation unit (16) presents a communicating interrogation antenna (20).

Abstract: An identification and/or sensor system includes a sensor that queries an identification and/or sensor configuration which contains resonators. A receiver receives an answer signal from the identification and/or sensor configuration. The receiver includes a phase-locked loop for converting a resonator decay signal into a signal of constant frequency and constant envelope curve.
