    摘要: An identification and/or sensor system includes an identification and/or sensor configuration having resonators for determining at least one parameter to be interrogated. The resonators have a quality being good enough to effect a storage of energy in the resonators. A transmitting and receiving apparatus transmits interrogation signals by radio to the identification and/or sensor configuration and receives and evaluates reply signals transmitted back from the identification and/or sensor configuration. The transmitting and receiving apparatus is a broadband device.

    摘要: A surface wave reflection filter includes an input transducer, an output transducer, and a reflector in a first propagation track. To compensate for undesired surface waves proceeding directly between the input and output transducers, as opposed to the desired surface waves which are reflected before reaching the output transducer, a second propagation track is provided. The second track includes a input transducer and an output transducer, and is either connected in phase opposition to compensate for the undesired signal, or is constructed to generate a signal in phase opposition. A sump may be provided in the second track, a second reflector may be provided in the first track or in the second track, and the two tracks may be on separate or the same substrates.

    摘要: A rotating motion sensor includes at least one electroacoustic resonator to stimulate a surface acoustic wave. The at least one electroacoustic resonator is configured so that rotation of the at least one electroacoustic resonator about an axis of rotation causes a change in resonance frequency of the at least one electroacoustic resonator. The at least one electroacoustic resonator includes oscillating structures configured to oscillate in a first direction that is a direction of propagation of the surface acoustic wave and/or a second direction that is transverse to the direction of propagation of the surface acoustic wave.
