  • Patent number: 10661701
    Abstract: A blade receives light emitted from a light source and repeats a predetermined periodic motion to scan the front of a vehicle with reflected light of the emitted light. A position detector generates a position detection signal S4 indicating a timing at which a predetermined reference point of the blade passes a predetermined position. Based on the position detection signal S4, a period calculator calculates a period Tp of the periodic motion of the blade. A light intensity calculator receives light-distribution-pattern information S3 to be formed in front of the vehicle and calculates light intensity to be generated by the light source at each time based on the position detection signal S4 and the period Tp. A driver turns on a semiconductor light source so as to obtain the light intensity calculated by the light intensity calculator at each time.

  • Patent number: 10143929
    Abstract: A portable electronic device 100 includes a horizontally long casing, both ends of which are gripped by a user's both hands, respectively. The device further includes a LCD fit into the front face of the casing 10. Outwardly projecting bulges are respectively formed at both sides of the rear face of the casing where fingers of the user gripping the casing 10 placed. Since the fingers and palms are naturally flexed to fit to the dome-like bulges 42L, 42R, the portable electronic device 100 fits comfortably in the user's hands. The operability is hard to be degraded even if the device is vibrated strongly during a game play with the device.

  • Patent number: 9598000
    Abstract: A vehicle lamp system includes a camera which generates image information in a front region, a controller which generates a light distribution command for instructing a light distribution pattern based on the image information, a headlight which irradiates the front region such that the instructed light distribution pattern is obtained, and a position calibrator which detects a positional deviation between the camera and the headlight. The position calibrator detects a reference object based on the image information and measures a luminance of the reference object, and when there is a certain difference between a luminance of the reference object obtained from one light distribution pattern and a luminance of the reference object obtained from another light distribution pattern in which a light quantity of only a part is different from the one light distribution pattern, detects the positional deviation using a position of the part.
