摘要:
The invention relates to a drive for adjusting motor vehicle seats comprising a spindle (5) fixed to a first (4) of two rails (3, 4) which are adjustable with respect to each other with the aid of holding devices (60) arranged on the end of the spindle (5). A transmission (9) actuated by a motor (2) is placed on the second rail (3), According to id invention, the holding devices (60) comprise an external bowl-shaped supporting surface (66) in which each end of the spindle (5) is fixedly mounted, respectively. Said solution is more advantageous in comparison with conventional holding devices which are embodied in the form of flexible stamped parts, in particular the inventive holding devices exhibit a high resistance in the case of crash.

摘要:
A longitudinal adjuster, in particular for a vehicle seat, has at least one first seat rail (2) and, at least one second seat rail (3) which is arranged in a manner such that it can be displaced in a sliding manner relative to the first seat rail (2), and at least one end stop (11, 21, 31, 41, 51) which is attached to the first seat rail (2) and limits the relative displaceability of the two seat rails (2, 3) to each other by means of interaction with a second end stop (3a) which is formed by the second seat rail (3) or is attached to same. The first seat rail (2) is provided with at least two apertures (2e) through each of which protrudes a region of the end stop (11, 21, 31, 41, 51) serving to limit the seat rail movement in the longitudinal direction of the seat rails (2, 3), and the region is formed by a respective tab (11a, 21a, 31a, 41a, 51a); formed integrally with the end stop (11, 21, 31, 41, 51). The associated aperture (2e) is formed in each case by a slot (2e) in the first seat rail (2), and the two tabs (11a, 21a, 31a, 41a, 51a) are arranged at the same height in the longitudinal direction of the seat rail (2).

摘要:
A system, apparatus and method for providing filtering functionality and impedance transformation within a BAW resonator network are disclosed. In particular, a BAW resonator network is designed to provide bandpass capability and a transformation between its input impedance and output impedance. By effectively integrating impedance matching functionality within the BAW resonator network, discrete impedance matching elements previously required within a system may be removed or reduced in size. As a result, matching networks and their associated component costs, insertion losses, and board size contributions may be reduced. Harmonic termination may be provided within the BAW resonator network or a prematch stage to improve efficiency of a power amplifier.
摘要:
A radio system includes a radio frequency (RF) integrated circuit (IC) and a baseband digital signal processing (DSP) IC. A serial digital interface couples data between the RF IC and the DSP IC to provide a high data rate and low noise. In one embodiment, the RF IC has a single bit sigma delta modulator to convert an analog signal into a serial digital bit stream, and a differential output driver to drive the serial digital bit stream as a differential data signal. In one embodiment, the DSP IC has a differential input receiver to receive the differential data signal and generate the serial digital bit stream therein, a decimator to lower the data rate of the serial digital bit stream and convert it into parallel digital data samples, and a demodulator to digitally demodulate the parallel digital data samples into data words for digital signal processing.

A longitudinal adjuster (3) for a vehicle seat (1), particularly a motor vehicle seat, has at least one first seat track (5) having catches (20) disposed in at least one row running in the longitudinal axis (x) of the seat. Each catch (20) includes a front flank (21a) and a rear flank (21a) in the longitudinal axis (x) of the seat, and at least one second seat track (8) that can be displaced relative to the first seat track (5) in the longitudinal axis (x) of the seat and locked to the same and at least two catch plates (12) for locking the first seat track (5) to the second seat track (8). The catch plates (12) are displaceably supported in the locking direction (z) in the second seat track (8) and comprise teeth (12b) for engaging in the catches (20) of the first seat track (5). Each tooth (12b) includes a front and a rear tooth flank (12d) in the longitudinal axis (x) of the seat. Each of the catch plates (12) includes exactly two teeth (12b) per associated row of catches (20). Two teeth (12b) belonging to different catch plates (12) act together with the row of catches (20) associated with said teeth (12b) for locking the first seat track (5) to the second seat track (8) with no clearance.
