摘要： A chuck with triaxial construction comprises a receiving surface for a test substrate and arranged below the receiving surface: an electrically conductive first surface element, an electrically conductive second surface element electrically insulated therefrom, and an electrically conductive third surface element electrically insulated therefrom, and, between the first and the second surface element, a first insulation element and, between the second and the third surface element, a second insulation element. A chuck for very low current measurements which can be used to prevent the occurrence of leakage currents and a triboelectric charge and which is configured favourably in terms of production, is achieved because at least one of the electrically conductive surface elements is mechanically connected to at least one insulation element and has an elasticity that compensates for an expansion difference resulting from differences in different coefficients of expansion between a respective surface element and an adjoining insulation element.

摘要： An audio transmission system including a wireless digital microphone unit which detects audio signals and wirelessly transmits the detected audio signals based on adjustable transmission settings and transmission parameters, and a central unit. The central unit has a monitor unit for monitoring and analyzing a frequency spectrum of an available frequency band, a link adaptation unit which adapts the microphone's transmission settings and parameters based on the results of the monitor unit, and a transmitting/receiving unit for receiving wirelessly transmitted audio signals from the wireless microphone unit and for transmitting transmission settings and transmission parameters via a return channel to the wireless microphone unit. The microphone's transmission settings and parameters are modified based on the transmission settings and transmission parameters transmitted via the return channel, which have a center frequency of a channel, a selection of a modulation method and parameters thereof, a data rate, and/or a channel encoding.

摘要： In a method and a device for testing a test substrate under defined thermal conditions, a substrate that is to be tested is held by a temperature-controllable chuck and is set to a defined temperature; the test substrate is positioned relative to test probes by at least one positioning device; and the test probes make contact with the test substrate for testing purposes. At least one component of the positioning device that is present in the vicinity of the temperature-controlled test substrate is set to a temperature that is independent of the temperature of the test substrate by a temperature-controlling device, and this temperature is held constant.

摘要： A method and device for the pictorial representation of space-related data, for example, geographical data of the earth. Such methods are used for visualising topographical or meteorological data in the form of weather maps or weather forecast films. Further fields of application are found in tourism, in traffic control, in navigation aids and also in studio technology. The space-related data, for example topography, actual cloud distribution, configurations of roads, rivers or frontiers, satellite images, actual temperatures, historical views, CAD-models, actual camera shots, are called up, stored or generated in a spatially distributed fashion. For a screen representation of a view of the object according to a field of view of a virtual observer, the required data are called up and shown only in the resolution required for each individual section of the image. The sub-division of the image into sections with different spatial resolutions is preferably effected according to the method of a binary or quadrant tree.

摘要： There is provided an interface adapter for receiving a microphone, wherein the interface adapter has a receiving unit with a through hole for receiving a microphone and an arresting unit for arresting a received microphone. That permits the microphone to be easily fixed on a boundary surface or interface, such as for example on a table top, a glass plate, tiles, wooden floors, concrete floors and the like. In other words the use of the interface adapter defines an interface which plays an important part in audio recording.

摘要： The invention relates to a preamplifier circuit with at least one transistor that couples a signal input to a signal output. The signal input is supplied with a radio-frequency signal. In addition, the preamplifier circuit includes a switch that switchably couples the input to a reference potential and which, when the preamplifier is inactive, is closed. Hence, when the preamplifier is inactive, the input is put into a low-impedance state and the amplifier and downstream assemblies are protected from unwanted high-power interference signals. It is thus also possible to use other, fully integratable filter types in a transceiver's reception signal processing chain instead of external surface acoustic wave filters with a low level of complexity and without drawbacks.
