Abstract: A circuit arrangement is disclosed with a radio-frequency mixer in which a plurality of preamplifiers in a receiver have a common output node. This node is connected to a common, broadband radio-frequency mixer via common coupling capacitances. Switching means can be used to connect and disconnect the preamplifiers, which can be associated with various frequency bands, independently of one another. The present principle can be applied in multiband receivers in mobile radio and allows integration using little chip area with good radio-frequency characteristics.

Abstract: An approach is provided for automatic geo-location search learning. A geo-location search learning platform receives a query specifying words, and initiates a point-of-interest search on the query, an address search on the query, and a partial search on some of the words. The geo-location search learning platform then combines results of the point-of-interest search, the address search, and the partial search, determines context information for a user; and sorts the combined results based on the context information thereby recommending the researched results to the user in a priority list as sorted.

Abstract: 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.

Abstract: The invention specifies a circuit arrangement with a radio-frequency mixer (4) in which a plurality of preamplifiers (1, 2, 3) in a receiver have a common output node (6). This node is connected to a common, broadband radio-frequency mixer (4) via common coupling capacitances (41, 42). Switching means (17, 18; 27, 28; 37, 38) can be used to connect and disconnect the preamplifiers (1 to 3), which can be associated with various frequency bands, independently of one another. The present principle can be applied in multiband receivers in mobile radio and allows integration using little chip area with good radio-frequency characteristics.

Abstract: 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.

Abstract: A probe support for holding probes which serve for electrical contacting of test substrates in a prober for testing purposes comprises a probe card holder, a probe card, and a probe card adapter, The probe card and probe card adapter are electrically connected to one another as well as to a shield of electrically conductive material and are disposed such that the probe card lies in a passageway of a shield. The shield is disposed between the test substrates and the probe card holder and is electrically insulated from the holder. For testing test substrates their positioning with respect to the probes held in this manner is done by angular alignment of the contact surfaces of the test substrates to the sensor tips and the movement of the test substrates along a path which starts from a first reference position and is composed up to the first, and each additional, contact position of an x-component and a y-component.

Abstract: 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.

Abstract: 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.
