  • Patent number: 11745813
    Abstract: An automated vehicle inspection system includes a diagnostic terminal mounted in a vehicle and connected to an engine control unit (ECU) of the vehicle, sequentially operating individual electric components through the ECU based on stored electric component inspection items while the vehicle passes through a watertight booth and receiving individual operating currents measured to determine whether the electric components normally operate, a transceiver connecting to the diagnostic terminal and a wireless diagnostic communication network through an antenna disposed in the watertight booth process line, and an inspector recognizing a vehicle ID of a vehicle that enters the watertight booth, transmitting inspection items according to a vehicle type and specification of the vehicle ID to the diagnostic terminal through the diagnostic communication network, and recognizing a vehicle ID of a vehicle that leaves the watertight booth to collect inspection results determined in the diagnostic terminal.

  • Patent number: 8466979
    Abstract: A digital image processor and method of improving user recognition in the digital image processor are provided. The digital image processor includes a view finder for a user to view a subject and a display unit on which an image is electrically realized, the digital image processor includes: a sensing unit for sensing rotation of the digital image processor; a detecting unit disposed at one side of the view finder and comprising an emission unit for emitting light and a light receiving unit for receiving light reflected by the user; and a control unit for increasing time for emitting light from the emission unit when the rotation is sensed by the sensing unit and controlling power supply to the display unit based on an output value corresponding to an amount of incident light onto the light receiving unit.
