摘要:
Various embodiments may provide a circuit including a radio frequency (RF) power amplification module having an RF power amplifier. The RF power amplification module may further include a directional coupler coupled with the RF power amplifier and configured to produce a power signal at a coupling port of the directional coupler corresponding to an output power of the RF power amplifier. The RF power amplification module may further include a switch coupled between the coupling terminal and a sensing path to selectively couple the coupling port with a power detector via the sensing path. The RF power amplification module may further include a termination load coupled to an isolation port of the directional coupler. Some embodiments may include a plurality of RF power amplification modules coupled together by the sensing path.

The present invention relates to a transmitting device and to a receiving device. In particular, it relates to a transmitting device for producing an analogue modulated pulse train and for emitting the same, comprising a pulse generator (1), with which a pulse train with an individual pulse form can be produced such that the pulse train falls in the frequency range into a predefined frequency band and/or into a predefined frequency mask, a modulation unit (2) which is connected to the pulse generator and with which a pulse train produced and/or to be produced by the pulse generator can be analogue-modulated by means of a predefined modulation scheme with respect to the amplitude thereof and/or the position of the individual pulses thereof, and an emitting unit (3), in particular an antenna, which is connected to the pulse generator and/or to the modulation unit and is suitable for emitting in the predefined frequency band and/or in the frequency range of the predefined frequency mask, with which emitting unit the analogue modulated pulse train can be emitted, in particular beamed.
摘要:
A motor vehicle roof with a fixed roof structure having a roof opening, two successive adjustable covers for closing and at least partially clearing the roof opening. At least one of the covers is selectively movable longitudinally out of its closed position into an open position and both of the covers are selectively pivotable out of their closed positions into a ventilation position.
摘要:
A frame arrangement for a vehicle roof that has a roof opening that is closable by a displaceable cover panel that, along with driving and guiding components thereof, is supported on a frame bounding the roof opening which has only the function of a support, i.e., does not form a necessary part of a fully functional installation unit, comprising a guide insert and a covering. The guide insert and the covering form the tracks for a slidable guide element and the cable guide channels for actuating cables, which interact with an appropriately suitable actuation device for displacing the cover panel. The guide insert can be made of plastic or metal, and the covering is advantageously divided into a front side section and side sections. These sections of the covering can be uniformly produced of plastic or metal or individual sections can be produced of plastic and others, in turn, of metal. Also, the guide insert as well as the covering can be produced entirely of plastic. Further, the guide insert can also form a guide for a sliding internal headliner panel.
摘要:
Flexible thermoplastic rack bar for meshing with a gear wheel, particularly for the drive of displaceable vehicle elements, like roof elements, sliding windows, and the like, having a series of supported teeth and a pull-resistant reinforcement embedded essentially parallel to a pitch line of the rack bar. The rack bar teeth are supported on at each lateral side and the reinforcement is disposed only in a cross-sectional area of the rack bar which lies heightwise between the head and the root of the rack bar teeth, preferably, substantially along a central transverse plane of the rack bar.

A sliding type vehicle roof is provided having guide tubes for pressure-resistant drive cables that are positioned, in the zone of contact area between the drive cables and a drive device, in a sheathing part that is formed about the guide tubes and acts as a holding device for the guide tubes. In the sheathing part, there is provided at least one recess to accommodate a drive pinion of the drive device, and a central opening in the base of the recess for accurately locating the drive pinion. Further, the sheathing part functions as a support for the drive device, that is suitably attached to the sheathing part with the aid of screws, and a defined seat can be provided on the sheathing part to receive the top housing part of the drive device. The sheathing part with the drive thereon can be attached to the frame, which can be set into a roof opening of a vehicle roof.
摘要:
An openable motor vehicle roof with at least one cover which selectively closes the roof opening by means of a raising and displacement mechanism (crank path, crank pin, drive carriage) and at least partially clears it by raising or lowering its rear edge and by displacement along a guide rail, with a locking element which locks an element connected to the cover with the guide rail in the closed position and the raised position. For reliable and low-wear interlocking of the cover mechanism in the closed and raised position, with a simple structure, it is provided that, in a sliding and lifting roof with a cover which can be lowered and can be pushed under the fixed vehicle roof, there is a locking element on the locking lever which is pivotally located on a component (cover carrier) which is connected to the cover being disengaged from the guide rail toward the end of the lowering motion of the cover which precedes the displacement motion.
摘要:
A sliding motor vehicle roof with two rigid covers (10, 11) for closing and at least partially exposing a roof opening (12) which is bordered by the roof frame in the fixed roof surface (13), with an displacement means for the ventilation position of the two covers (10, 11), and with a head liner which has a front and a rear headliner part (14, 15) and which can be moved at least partially independently of the cover position in the direction of the lengthwise axis of the motor vehicle by the displacement means. It is provided that, in order to produce the front horizontal ventilation gap (16) in front of the front edge of the front headliner part (14) and the rear horizontal ventilation gap (17) between the two headliner parts (14, 15), the front headliner part (14) is coupled to the rear headliner part (15). The front headliner part (14) can be moved from the closed position into the position which opens the front ventilation gap (16), and the rear headliner part (15) can be moved away from the front headliner part (14) by the ventilation position motion of the cover (10, 11) to clear the rear ventilation gap (17).
