Abstract: The present invention relates to a method and apparatus for providing configuration information to terminals and network components within a network. In particular, a specialist is no longer necessary in order to exchange a terminal or a component for the network. The network user simply exchanges the terminal or the network component and places a configuration storage adapter in a serial interface of the replaced terminal or component, whereby the newly inserted terminal or network component is automatically provided with stored configuration information and the network can then be started.

Abstract: The invention relates to a vehicle antenna (1), designed to be mounted on a vehicle surface (4). Said antenna comprises a base body (2) consisting of metal and a plastic antenna housing (3), which surrounds the antenna elements that are placed on the base body (2). According to the invention, the base body (2) has at least one sub-section (2.2) consisting of plastic and the antenna housing (3) is permanently connected to said sub-section (2.2) once the antenna elements have been mounted.

Abstract: A housing assembly for a printed circuit board is mounted on a vehicle body by pressing a collar nut or the head of a collar screw past a plurality of fingers of a housing assembly so that the fingers retain the nut or screw head in place. The module is then pressed against the vehicle body so that the collar nut or collar screw is lifted while the retainers are deflected outwardly and a tool is used to tighten the screw into a nut or the nut onto the shank of a screw to clamp the printed circuit board on the housing against the vehicle body.

Abstract: A flat base plate sits atop a motor-vehicle panel and is formed with a mounting pin extending downward through the panel. A flat antenna circuit board sits on the base plate, and a connector cable extends upward through the pin and through the base plate and is connected to the circuit board. A one-piece mounting element is unitarily formed with an upper face and latch legs projecting upward from the upper face and having barb ends latchingly engageable with the circuit board to retain the circuit board on the upper face. It is further unitarily formed with a lower face and latch legs projecting downward from the lower face through the base plate and roof panel and having barb ends latchingly engageable with the roof panel to hold the circuit board and base plate down against the roof panel.

Abstract: A housing for an electronic device in automotive technology has two molded-plastic housing parts fittable together to form a cavity and a membrane hinge unitarily formed with the parts and permitting relative pivoting of the parts between an open position and a closed position. The electronic device is secured in the cavity between the parts. Respective snap formations on the parts are fittable together only in the closed position in a condition of one of the parts bearing with prestress on the other part for securing the parts together against separation. One of the snap formations is elastically deformable transversely of an opening direction into and out of latching engagement with the other of the formations.

Abstract: A cliplike contact element which can be used to provide an electrical contact between an antenna amplifier mounted on a body of an automotive vehicle and an antenna structure on a window of the vehicle has two interfitting contact partners with the outer contact partner having at least an electrically-conductive surface hugging the conductive surface of the inner contact partner. The contact partners can be bonded, e.g. by soldering to respective conductors.

Abstract: A method of producing an antenna structure for an automotive vehicle comprising the steps of providing a substrate element and arranging the antenna structure on one surface of the substrate element.

Abstract: A contact spring assembly has a contact plate with a window in which a contact spring is received, the contact spring having bent strips engageable with an antenna amplifier and an antenna amplifier structure. The contact spring is fixed at one end and movable at its other end on the support plate.

Abstract: A contacting device, especially for an antenna amplifier in an automotive application to contact an antenna on a windshield or rear window of the vehicle has a lever-like contact element in the form of a strap or stirrup and bends lying in a plane and bearing upon the surfaces and bridging between them.

Abstract: A coupler for a coaxial plug and connectable with a cable, especially an antenna coupler with an outer conductive sleeve comprised entirely or partly of metal and formed by bending from a blank whose basic shape is produced by stamping or punching from steel metal.

Abstract: An adapter for making contact between an antenna structure on a window pane of an automotive vehicle and the antenna signal processing unit which can be positioned at an optional location thereon as plug connectors for flexible leads running to the signal processing window and contact elements which are yieldable and bear against the conductive pads of the antenna structure. The adapter can be mounted at any optional location on the vehicle body.

Abstract: An antenna assembly for a motor vehicle has a housing mounted on the vehicle body and overhanging a portion of a window provided with an antenna connector structure. A carrier removably mounted on that housing has one or more contact elements which bear directly against a printed circuit board in the housing and carrying the antenna signal processing circuitry and against the antenna conductor structure on the window.

Abstract: An adapter between an antenna amplifier and an antenna conductor structure can have a spring biased slider bearing against a flexible strip conductor to press it against the contacts of the antenna conductor structure of a vehicle window.

Abstract: The invention relates to an antenna system (1) comprising several antennae (2), which can be connected to at least two receivers (4, 4?) via a combination unit. According to the invention, a signal processing unit (5) for evaluating the output signals of the receivers (4, 4?) and a control unit (10) are provided, by means of which at least one of the antennae can be switched to transmit mode in order to conduct a self-test. These antennae (2) transmit test signals with a test frequency that is pre-set by a first receiver (4). Said test signals are fed into at least one other antenna (2) that, via the combination device (3), is connected to the second receiver (4?) whose frequency is tuned to the test frequency. In order to conduct the self-test, the receiving levels of the second receiver (4?) are recorded as actual values and compared with predetermined set values. This results in the realization of an antenna system in which a function check is conducted with the least possible amount of complexity.

Abstract: A method of transmitting digital signals which are passed via a communication system by means of a retimer between an input and an output, whereby according to the invention the data packet applied to the input is scanned with respect to the individual bits and within the individual bits and preferably at the center and the scanned data level is transmitted immediately to the output.

Abstract: A printed-circuit board is formed at a front edge with a cutout. A plug has a base body adapted to fit in the cutout and formed with a pair of shoulders bearing flatly on the board at edges of the cutout. A pair of wing-shaped connecting elements project oppositely from the body and lie flatly on the board adjacent the edges of the cutout so that the elements can be soldered to the board to fix the base body in the cutout.
