  • Patent number: 8010255
    Abstract: A movable or removable seat for a motor vehicle is disclosed which preferably takes the form of a re-movable vehicle seat (1). The removable seat incorporates a first inductor (17) which forms part of an inductive coupling between the removable seat and a second inductor (21) which is mounted on the motor vehicle. The first inductor forms part of a resonant circuit which incorporates at least one capacitor. The resonant frequency of the resonant circuit is variable in response to a sensed parameter such as, for example, the position of a head-rest of the seat, the inclination of the back-rest of the seat and such like. A central unit (23) generates a square wave which excites the resonant circuit. A signal is transmitted from the resonant circuit to the central unit (23) which analyses the resonant frequency of the resonant circuit.

  • Patent number: 7995095
    Abstract: In a night vision arrangement for a motor vehicle in which a camera captures an infra-red image of the roadway in front of the vehicle, a video signal generated by the camera is processed by a signal processor so that the field of view of the image displayed by a display unit is selected in accordance with a control signal. The control signal is generated by a signal generator which is responsive to one or more parameters of the movement of the vehicle. The width of the field of view may be decreased with increasing speed. The axial direction of the field of view may be adjusted depending upon the nature of a turning movement of the vehicle.

  • Patent number: 7995107
    Abstract: A method of obtaining a spatial low pass filtered images from the video output of a video camera operable to produce successive video frames in the form of pixelated 2D sensed images. Each of the sensed images has a first predetermined number of rows of pixels and a second predetermined number of columns of pixels. The method may include scanning the sensor array row by row, and deriving the value of each pixel of said low spatial frequency image in such a way that said low spatial frequency value of a pixel is dependent on at least all earlier scanned pixels of the current row and all earlier scanned rows, but is not dependent on the pixels of rows located below a pixel row which is a third predetermined number of rows below the current row, said third predetermined number being significantly less than said first predetermined number.

  • Patent number: 7988188
    Abstract: A side airbag (10) for a motor vehicle comprises an airbag shell that surrounds a gas compartment and has at least one opening. A hose (20) has an outlet opening (22) and is located on the outside of the airbag shell. When the hose is in a state in which it is not under pressure, the hose connects the opening (16) to the outlet opening (22), and thereby to the surrounding area. The hose (20) comprises a first section (20a), which is situated at the height of the opening (16), and a second section (20b), which connects the first section (20a) to the outlet opening (22). The ventilation arrangement composed of the opening (16) and the hose (20) is used to make the side airbag hard for a large occupant and soft for a small occupant. In order to improve the behavior of the side airbag for a small occupant, without impairing the behavior thereof for a large occupant, the maximum cross-section of the first section (20a) is larger than the minimum cross-section of the second section (20b).

  • Patent number: 7980593
    Abstract: A passenger airbag module equipped with an airbag cushion and a tether holder used in a vehicle. The tether holder holds a tether prior to inflating the airbag cushion and inhibits twisting of the tether during deployment of the tether when the airbag cushion is inflated. When the tether is deployed without being twisted or folded, the deployment length of the tether is not reduced. Thus, the airbag is more consistently deployed and inflated.
