  • Patent number: 11081084
    Abstract: Provided is an electronic apparatus in which an illuminance sensor is arranged on the back side of a display unit, and which can perform the appropriate luminance adjustment. The electronic apparatus includes a display unit, an illuminance sensor, a luminance control unit, and an operation judgement unit. The illuminance sensor is disposed on back side of the display surface of the display unit. The luminance control unit controls the luminance of the display unit based on the information related to light detected by the illuminance sensor. The operation judgement unit judges reliability of the information related to light detected by the illuminance sensor. The luminance control unit controls the luminance of the display unit when reliability is judged to be high. The luminance control unit suppresses control of the luminance of the display unit when reliability is judged to be low.

  • Patent number: 11035533
    Abstract: A bendable lamp that includes an open topped base with an upwardly projecting LED lighting source. A translucent accordion bellows sleeve is attached at one end to the open topped base. The sleeve can be vertically extended or retracted by the user. The nature of the pleats of the accordion sleeve allow the resulting structure to remain in the position that the user pulled, compressed or bent it to. The sleeve can be bent to an inverted J or inverted U shape, and its height can be adjusted. A weight in the lamp's base keeps the lamp from falling over. The LED lights can be programmed by a microprocessor.
