  • Patent number: 10882552
    Abstract: A control method of a rear wheel steering system prevents a sudden change in a rear wheel steering control amount when an error occurs in a wheel speed sensor. The control method detects an error in wheel speed sensors based on output values of the wheel speed sensors. A vehicle speed is estimated by using output values of remaining normal wheel speed sensors except for an output value of an abnormal wheel speed sensor where an error is detected, when an error in the wheel speed sensor is detected. Rear wheels are steered and controlled based on the estimated vehicle speed.

  • Patent number: 10803367
    Abstract: A method and an apparatus for recognizing characters using an image are provided. A camera is activated according to a character recognition request and a preview mode is set for displaying an image photographed through the camera in real time. An auto focus of the camera is controlled and an image having a predetermined level of clarity is obtained for character recognition from the images obtained in the preview mode. The image for character recognition is character-recognition-processed so as to extract recognition result data. A final recognition character row is drawn that excludes non-character data from the recognition result data. A first word is combined including at least one character of the final recognition character row and a predetermined maximum number of characters. A dictionary database that stores dictionary information on various languages using the first word is searched, so as to provide the user with the corresponding word.

  • Patent number: 10796737
    Abstract: A semiconductor apparatus includes a clock path, a command path, a delay monitoring circuit, and an output control circuit. The clock path generates a delay clock signal by delaying a clock signal. The command path generates an output command signal from on one of a command signal and the clock signal, based on a monitoring signal. The delay monitoring circuit generates a delay control signal and a latency control signal based on a phase difference between the delay clock signal and the output command signal, when the monitoring signal is enabled. The output control circuit generates an output enable signal by synchronizing the output command signal with the delay clock signal, based on the latency control signal.
