  • Patent number: 6783073
    Abstract: An image input system includes a solid state image pickup device and a preprocessor for performing correlated double sampling amplification on an output of the image pickup device and outputting a video signal. The preprocessor has a correlated double sampling amplifier for outputting signal information corresponding to a difference voltage between the black level in a feedthrough period of the image pickup device and a signal level in a charge signal output period; and an offset cancelling circuit for cancelling an offset voltage corresponding to the difference voltage in a state where the image pickup device is optically interrupted to the input terminal of the correlated double sampling amplifier. The correlated double sampling amplifier cancels out the offset voltage and the offset cancelling voltage as signal components of polarities opposite to each other, so that circuits following the correlated double sampling amplifier are not influenced by the offset voltage.

  • Patent number: 6781107
    Abstract: In an imaging system having a semiconductor integrated circuit device, noise problems due to a large through-current in an output circuit resulting from the change-over of digital video data outputted from an AD conversion LSI are reduced by a technique involving encoding and code conversion. After AD conversion of an analog color video signal from an imaging element, a difference between codes of adjacent pixels is obtained in regard to the same color, and an output code of this difference is converted into a code with less change-over bits between the adjacent codes.

  • Publication number: 20030209891
    Abstract: A structure of arranging an vehicle occupant protecting apparatus for an automotive vehicle, which can prevent a pillar garnish from scattering when an air bag installed in a front pillar portion is expanded, is provided. An air bag 16 is housed within a space formed by a front pillar main body 38 and a pillar garnish 40 in a front pillar portion 20. When the air bag 16 expands, the pillar garnish 40 is pressed by an expanding pressure of the air bag 16, so that an opening for expanding the air bag 16 is formed between the front pillar main body 38 and the pillar garnish 40, and the air bag 16 expands into a vehicle cabin through the opening. Since a non-expanding portion is formed at the air bag 16 and a hinge portion 46 is formed at the pillar garnish 40, the expanding pressure applied to the pillar garnish 40 when the air bag 16 expand is low, so that the pillar garnish 40 can be easily opened through the hinge portion 46.

  • Patent number: 6530594
    Abstract: A jump-up stand is disposed below a folded air bag body and is also provided over a region from a position near a front side of a center pillar to the center pillar. The jump-up stand is formed from a plate material which is bent to have a substantially L-shaped cross sectional configuration and includes a wall portion extending toward an upper end of a center pillar garnish. Accordingly, when the air bag body expands, the air bag body expands toward the interior of a vehicle along the wall portion of the jump-up stand so as to prevent large load from acting on the upper end of the center pillar garnish.

  • Publication number: 20020179821
    Abstract: An AD-converted digital video data is encoded by a difference encoding method before it is outputted and such encoded digital video data is then outputted after it is converted to the gray code or to the predetermined code in which a fixed value is added. Thereby, the problems that power supply noise generated when the AD conversion circuit outputs a video data migrates into the CCD side via the power supply line (Vcc line and ground line) on the printed circuit board and that the power supply noise appears on the display image by migration into the input terminal side from the output circuit side via the power supply line and semiconductor substrate within the AD conversion LSI in the existing imaging system can be solved.

  • Patent number: 6334626
    Abstract: An interior equipment mounting structure for a vehicle incorporating a head-protecting air bag body, a roof head lining, which is deformed at the time of expansion of the air bag body, includes a sun visor and an arm. The sun visor is connected to a vehicle body and is movable from an accommodated state to at least one predetermined position for use. The sun visor is connected to the vehicle body by the arm. The sun visor is formed by a main body portion and by an overhang portion. When a load of a predetermined value or more acts on the overhang portion by the expansion of the air bag body, the overhang portion is easily deformable with respect to the main body portion.

  • Patent number: 6279941
    Abstract: Mounting portions of an air bag body are respectively nipped by positioning plates which are each fastened and fixed to a pillar inner panel by a weld nut and a bolt via the plates. Caulking portions are formed on the plates so that the mounting portions of the air bag device are in advance fixed between the plates. A convex portion is formed on the plate, and with the convex portion being engaged with a hole formed in the pillar inner panel, relative rotation of the plate and a vehicle body is prevented. As a result, rotation of the air bag body in a direction in which the mounting portions are fastened, which occurs during mounting of the air bag body to the vehicle body, can be prevented.

  • Publication number: 20010000290
    Abstract: During a collision, an air bag causes deformation of a roof head lining as the air bag expands. A roof head lining deformation limiting structure restricts inward deformation of the roof head lining. Thus, the roof head lining is prevented from interfering with an interior equipment, e.g., a sun visor, thereby reducing breakage of the sun visor provided adjacent the roof head lining. The deformation limiting structure can take the form of an assist grip or a card holder. Also, the assist grip or the card holder can be mounted onto a member, e.g., a bracket, that plastically deforms upon being struck by the occupant's head during a collision, thereby absorbing a portion of the impact that would otherwise be transferred to the occupant.
