Abstract: A display device includes: a display panel including a sensor unit configured to detect a touch operation; a first control unit configured to supply a first signal to the display panel; and a second control unit configured to calculate touch information related to the touch operation and to supply the touch information to the first control unit. The first control unit includes: a signal generator configured to generate the first signal based on an image signal supplied from an external image signal supply source; and an overdrive circuit configured to perform a process of increasing an amplitude of the first signal generated by the signal generator. The overdrive circuit is actuated based on the touch information from the second control unit. The first control unit, in response to the actuation of the overdrive circuit, supplies the first signal having the amplitude increased by the overdrive circuit to the display panel.

Abstract: An optical axis direction, a distance measurement accuracy and so on are efficiently performed for quality assurance of a vehicle-mounted camera in cooperation of an image processing unit and a vehicle-mounted navigation control unit. In a vehicle monitoring system for imaging view ahead of the vehicle with the camera (2a, 2b) installed in the vehicle body and for recognizing a running condition with the image processing unit (20), the image processing unit measures an optical axis direction and a distance measurement accuracy to determine whether the camera quality is appropriate or not for quality assurance of the vehicle-mounted camera. The determined result is displayed on a monitor (52) of the vehicle mounted navigation control unit (5) to recommend adjustment of the camera.

Abstract: A power window apparatus for a vehicle capable of switching an operation mode of a window to a submersion mode when a submersion of the vehicle is detected, includes a circuit board for controlling the window, a sensor having a pair of electrodes for detecting a continuity between the electrodes when the electrodes are submerged, a housing for accommodating the circuit board and the sensor, a first chamber provided in the housing and enclosed by walls for accommodating the circuit board, a second chamber provided in the housing and enclosed by walls for accommodating the sensor, and an opening provided at the walls of the second chamber for allowing to introduce water into the second chamber so as to merge the sensor in water before the circuit board is submerged.
