  • Publication number: 20260208692
    Abstract: A vehicle control system of one aspect includes: a first control unit that controls a modification of a target vehicle state performed by a target device included in a vehicle; and a second control unit that sets an operation mode of an alarm that is based on a change of the target vehicle state and performed by an alarm device included in the vehicle, in accordance with a control situation of the modification of the target vehicle state by the first control unit.

  • Publication number: 20260208621
    Abstract: A battery control system of one aspect includes: a battery state detection unit that detects a state value of a battery; a control unit that controls power supply from the battery to a vehicle based on the state value; and a door opening/closing detection unit that detects opening and closing of a door of the vehicle. The control unit interrupts the power supply from the battery to the vehicle when the state value is equal to or lower than a first threshold value, and restarts the interrupted power supply when an open state of the door is detected.

  • Patent number: 6680471
    Abstract: There is disclosed an apparatus in which when a surface having a curved portion, for example, a tire surface is visually inspected, light is uniformly illuminated on the surface. In this apparatus, an image pickup operation is performed by a CCD for a region to be visually inspected, which is illuminated by turning on LEDs. Based on the image pickup result, a density distribution of the region to be visually inspected is prepared. A difference between a target light quantity and light quantity, which is obtained for each field angle of the density distribution at which the region to be visually inspected is illuminated by each light source unit, is calculated and corrected. This correction allows the quantity of light reflected from the region to be visually inspected on the inner peripheral surface to become uniform.

  • Publication number: 20010025238
    Abstract: A multi-valued logic emulation system reads a specifying value for specifying with which value, logic emulation is performed, and represents the logic value by a plurality of physical signal lines equal to (Log2 a raised integer of the specifying value). Then, the system performs multi-value supporting synthesis and automatic place/automatic route processing, and maps resulting information to a programmable gate array, thereby making it possible to execute multi-valued logic emulation.

  • Patent number: 5904788
    Abstract: The present invention is a method and apparatus for centering a belt-shaped material. A conveying direction leading end portion and a conveying direction trailing end portion of triangular portions of the belt-shaped material are displaced in advance in directions opposite directions in which the conveying direction leading end portion and the conveying direction trailing end portion of the belt-shaped material are displaced when applied onto a forming drum. Centering of a constant-width portion of the belt-shaped material is carried out as follows. A width of the constant-width portion of the belt-shaped material is measured while the belt-shaped material is conveyed. In accordance with the measured width, a distance between a pair of guide portions which are disposed so as to be movable in a widthwise direction of the belt-shaped material is adjusted. The belt-shaped material is passed through a space between the adjusted guide portions.
