  • Publication number: 20230403447
    Abstract: Mobile computing devices often incorporate a digital camera module to capture photographs and/or record video using one or more built-in digital cameras and photoflash LEDs. The photoflash LEDs are separated from the digital cameras and sensors within the digital camera module to provide an optical barrier therebetween. To aid the physical separation, a flat translucent window over the digital cameras is typically not shared with the photoflash LEDs. Such separation efforts are visually and tactilely evident to a user and introduce gaps that can be a source of moisture and/or particulate entry into the computing device. The presently disclosed technology introduces a common flat translucent window over the digital camera and photoflash LEDs within the digital camera module. Features adopted into the shared flat translucent window provide sufficient optical separation between the photoflash LEDs and the nearby cameras within the digital camera module.

  • Patent number: 7636437
    Abstract: A telephone apparatus includes a body part and a sleeve-like grip part mounted to the body part for longitudinal slidable movement between a retracted position and an extended position. Mechanically coupled to the body part and the grip part there is a spring for effecting the longitudinal slidable movement. A locking mechanism is provided for detachably locking the body part and the grip part into the retracted position. There is also a user-actuatable releasing actuator for releasing the locking mechanism. The releasing actuator is located within the grip part.

  • Publication number: 20010036266
    Abstract: A telephone apparatus comprises a body part (601) and a sleeve-like grip part (602) mounted to the body part (601) for longitudinal slidable movement between a retracted position and an extended position. Mechanically coupled to the body part (601) and the grip part (602) there is a spring (700, 1203) for effecting the longitudinal slidable movement. A locking mechanism (1004, 1006, 1007) is provided for detachably locking the body part and the grip part into the retracted position. There is also a user-actuatable releasing actuator (1005) for releasing the locking mechanism. The releasing actuator (1005) is located within the grip part (602).
