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.

摘要： An electrical component has electrically conducting structures placed on an electrically isolating or semiconductive substrate and component structures sensitive to a voltage or an electrical arcing and galvanically separated from one another. To prevent an arcing between the galvanically separated component structures, the component structures are short-circuited with a shunt line having a smaller cross-section than the remaining electrical conductor tracks. The shunt lines can be burnt through by application of an electrical current at any given time, whereby a galvanic separation of the component structures is effected, if necessary, for the function of the component.

摘要： For a component operating with acoustic waves, it is proposed to arrange the electrode structure over a mechanically stable adaptation layer that serves to dissipate the electromechanical stresses. Further improvements of the output compatibility are achieved with additional intermediate layers and passivation layers applied on the sides or the entire surface over the electrode structure.

摘要： A capacitor with a multilayer structure on a ceramic or crystalline substrate is proposed that comprises at least one lower and one upper electrode as well as a tunable dielectric arranged therebetween in which resonant oscillation modes of bulk acoustic waves can be propagated, wherein, by suitable selection regarding material and thickness and a suitable number of layers in the multilayer structure, the latter is tuned such that the resonant frequencies of the oscillation modes lie outside of band ranges used in mobile telephones. Circuits with tunable capacitors that find multiple uses inside terminal devices for mobile communication are additionally proposed.

摘要： SAW component with improved temperature coefficient of frequency To reduce losses in a SAW component assembled on a piezoelectric substrate (S), the mass load on the metallization (M) is increased until the propagation velocity of the surface wave comes to rest below the propagation velocity of the fast shear wave. To limit the increase in the temperature coefficient of frequency in this process, a metallization with a significantly higher specific density than [that of] Al is used. The temperature coefficient of frequency of the component is simultaneously reduced by a compensation layer (K) applied to essentially the entire surface, said compensation layer being made of a material having a temperature dependency of the elastic coefficient that counteracts that of the substrate-metallization combination.

摘要： A device for determining whether a lubricant to be examined effects the formation of a deposit on a sensor element has a sensor element for detecting values of at least one physical parameter of the lubricant. The sensor element is in contact with the lubricant. Furthermore, there is provided a potential difference source for applying a potential difference between the sensor element and the lubricant. Moreover, there is provided an evaluator for evaluating at least two values of the physical parameter which are detected at different potential states between the sensor element and the lubricant in order to thus determine whether the lubricant causes a deposit formation on the sensor element.
