Abstract: A vehicle radar system (2) for detecting the surroundings, includes a circuit board (4), with a substrate layer (14) having an upper face (14a) and a lower face (14b), a strip conductor (22) applied onto the upper face (14a) so as to surround a shielding region (20), a shielding housing (6) that covers the shielding region (20) and that extends along and is connected to the strip conductor (22) in an electrically conductive manner, and at least one wave guide (28) arranged in the substrate layer. The wave guide (28) has a laterally delimiting wave guide wall (28c) as well as upper and lower wave guide surfaces (28a, 28b), wherein the upper wave guide surface (28a) is a section of the strip conductor (22).

Abstract: The disclosure relates to a radar system for registering the environment for a motor vehicle, with a circuit board includes a wave termination with a termination line, a signal line connected to it for the transmission of a high frequency signal, and a first substrate layer which is produced from a material with a first loss factor. The radar system also includes a first tier attached onto the first substrate layer, which includes the signal line, a second substrate layer which is produced from a second material with a second loss factor, which is greater than the first loss factor, and a second tier applied to the second substrate layer, which includes the termination line. Additionally, the disclosure relates to a circuit board for such a radar system.

Abstract: A head restraint assembly is provided with a head restraint frame mounted to a post for movement along the post for adjustment relative to a vehicle seat. The head restraint frame has a contact surface. A biasing member is mounted to the head restraint frame for movement relative to the head restraint frame to maintain the head restraint frame in a locked condition along the post. An actuation member is mounted to the head restraint frame for movement relative to the head restraint frame. The actuation member cooperates with the biasing member such that movement of the actuation member moves the biasing member, thereby disengaging the biasing member from the post to permit movement of the head restraint along the post such that the biasing member engages the contact surface in the second position to provide feedback to the user of an unlocked condition of the head restraint frame.

Abstract: An adjustable head restraint assembly is provided with a support rod adapted to be mounted proximate to a vehicle seat back. A primary frame is supported on the support rod. A secondary frame is mounted to the primary frame for translation in a fore and aft direction. A locking arm is pivotally connected to one of the frames for engagement with a series of notches formed in the other. A biasing member cooperates with a locking arm for biasing the locking arm into a locked position. An actuator pivots the locking arm out of engagement from the series of notches for unlocking the locking arm and permitting adjustment of the adjustable head restraint in the fore and aft direction. The primary frame translates along the support rod with a locking arm for engagement with notches in the support rod for movement by the actuator for adjustment in an upright direction.

Abstract: A method for producing a transmission signal, wherein an input signal (Vd(t)), which is to be amplified, is fed to a power amplifier (PA) which outputs the signal in an amplified form (va(t)). A reproduction thereof is made and allocates a specific pre-distortion input signal (vd(t)) value to a specific input signal (vd(t)) value. A corresponding pre-distortion value is then determined for the input signal (vd(t)) and the corresponding pre-distortion value is applied to the input signal (vd(t)) in order to feed the pre-distorted input signal to the power amplifier (PA). Subsequently, the crest factor (CF) is calculated from the output signal (vd(t)) of the power (PA) and the reproduction or the value thereof if the determined crest factor departs from a predetermined range of values.

Abstract: A method for improving the output power of a non-linear amplifier, wherein signal amplitudes of a digital baseband are predistorted and then fed at the input of the power amplifier, having a non-linear characteristic curve, in order to linearize the characteristic curve. The signal amplitudes are fed to the input of the power amplifier in a predistorted manner up to a predetermined transition power while being fed to the input of the power amplifier in a non-predistorted manner from the predetermined transition power on.
