摘要:
A system for exchanging data includes at least two memory units, each unit functioning as both a transmitter and a receiver of data. The exchange of data occurs whenever at least two memory units are within a certain distance of each other. The user is thus capable of simultaneously being both a transmitter and a receiver of data, such that the transmitter can send data continuously but can receive data transmitted from other memory units only when the receiver is within a certain distance from a transmitter. As a result, data are received only by those memory units that are located in the immediate environment of the transmitter. Since the data transmitted can be selected personally by the user, the data thus reflects the preferences of the user acting as the transmitter.

A Portable communications device (1), particularly as an additional functional unit in a radiotelephone (100), comprising an input, output radio interface (2) for local data exchange between two adjacent communications devices (1; 100) or between a communications device (1; 100) and a data processing device (12) adapted to the,local data exchange, or a data-reproducing device (13), or an adapted data source (50). The range (r) of the input/output radio interface (2) is short compared with the range of a conventional radio interface for data :transfer, and corresponds essentially to a talking distance. The communications device (1, 100) further includes a memory device (6) and a data processing device (5). Different data sequences are identified and selectively retrievable in the memory device (6). The activation of the input/output radio interface (2) can be initiated manually.

A measuring device for measuring or examining physiological parameters on biocomponents includes an FET sensor 5 whose electrical protective layer 12 is roughened or has a structured coating 15. The structuring of the active sensor contact surface 12 is adapted to the outer contour and topography of the biocomponent in question, so that a better possibility is available for anchoring the biocomponents to the contact surface 24 forming the FET protective layer of the sensor 5.
摘要:
A signal separator, particularly a teletext-signal separator, includes an integrating unit which delivers a center-of-bit-indicating (i.e., center-crossing) signal and a residual-value signal. A residual-value-signal-evaluating device evaluates the respective residual value and uses a selection control signal to determine how the value of the current signal bit is to be estimated. This is accomplished by using a selection facility which derives from the current sample value and the preceding and subsequent sample values the respective preaverage value and postaverage value and selects the value best suited for the estimation using the selection control signal. A phase corrector evaluates a signal pattern from an edge logic which indicates whether the current sample value is approaching an edge of the signal, and controls a change of the integration period if the residual-value signal lies within a predetermined residual value signal range.

A chip includes a memory that stores confidential data, a power supply device to apply a voltage and/or or a current, and an interface to transfer the data from and/or to another device. To secure the data in the memory, the power supply device is an integrated component of the chip. The power supply device is equipped with a limited, non-replenishable fuel reservoir so that data can be maintained in the memory over a limited service life. In other embodiments, voltage provided by the power supply device can also be employed actively to delete data in the memory in the event of unauthorized access to the chip.

Television receiver comprising a flat screen display which has a component interface unit spatially separate from the television receiver for the external terminals, such as, for example, SCART sockets or speaker terminals, the component interface unit being connected through at least one high-capacity bus connection to the television receiver. The bus connection is connected in the spatially separate component interface unit to first bus interfaces for signals to be fed in and out, and is connected in the television receiver to second bus interfaces.
摘要:
A processing device embodied in an integrated circuit may be divided into first and second functional units. A mount for the integrated circuit may be assigned to the first functional unit, which may define the external electrical connections of the processing device. Processing may take place in a second functional unit of the processing device, whose essential connections may normally be accessible from outside via the external connections of the first functional unit. The processor device having first and second functional units in a mount may be similar to a hybrid circuit but may serve a different purpose. The first functional unit, which may also comprise more than one monolithic integrated circuit, may define the external connections and may make available suitable matching circuits for the second functional unit. In this manner, the processing device, which may be contained in the second functional unit and may also comprise more than one monolithic integrated circuit, may be considered to be “masked” as viewed from outside. In addition to the matching circuits, the first functional unit may contain subcircuits performing more general functions, such as oscillators, supply voltage regulator circuits, buffer circuits, protective circuits, etc.
摘要:
A chip arrangement (1) has a substrate board (2) with an opening (3), into which a carrier chip (4) is inserted, which has an electrical or electronic structural component (5). At least one conductor path (7) is integrated into the carrier chip (4), which connects the structural component (5) to the electrical connection contact (8). The carrier chip (4) is inserted into the opening (3) in such a way that its ends project beyond the opposite-facing, flat-sided surfaces (9, 9′) of the substrate board (2), and thereby form overhangs (10, 10′). Here, the structural component is arranged on the overhang (10) projecting beyond the one surface (9), and the connection contact (8) is arranged on the overhang (10′) projecting beyond the other surface (9′), and the conductor path (7) connecting the structural component (5) and the connection contact (8) passes through the opening (3). A seal is arranged between the substrate board (2) and the carrier chip (4).
