  • Patent number: 12143724
    Abstract: A clamping device, an electronic device, and a remote control method of the electronic device. The clamping device includes a clamping unit, a first communication unit, and a control unit. The clamping unit is suitable for clamping the electronic device. The first communication unit is suitable for pairing with a second communication unit of the electronic device. The control unit is coupled to the clamping unit and the first communication unit. When the clamping unit is switched from an off mode to an on mode, the control unit controls the first communication unit to pair with the second communication unit and sends a screen-off command to the second communication unit via the first communication unit after the pairing is completed. When the clamping unit is in a clamping mode, the control unit sends an application open command to the second communication unit via the first communication unit.

  • Publication number: 20080320505
    Abstract: For the optical disc drive in the invention, the holder, the gear set and the transmission part and other components have mechanical interacting relationship, and therefore, when the power of the optical disc drive is cut off, the optical disc still can be ejected from the casing by the mechanical interaction of the components. An optical disc drive including a casing, a holder, a motor, a first and second gear sets, and a transmission part is provided. The holder which can move between a first and second position is disposed in the casing. When the holder moves to the second position, the second gear set is away from the first gear set at a distance, and the transmission part drives the disc to eject from the casing by the external force.

  • Patent number: 7233555
    Abstract: A method for adjusting an optical axis of an optical disc drive. The method includes the following steps. A first reflecting member is disposed on a turntable of the optical disc drive, and is rotated along with the turntable. A laser light is emitted on the first reflecting member by a laser collimator, and a normal vector of the turntable is measured based on a light point reflected to the laser collimator from the first reflecting member. A second reflecting member and a third reflecting member are disposed on a guide bar of the optical disc drive. A first initial vector and a second initial vector are measured based on a light point reflected to the laser collimator from the second reflecting member and the third reflecting member.

  • Patent number: 6938264
    Abstract: A lash-eliminating device for a worm-and-gear assembly. The worm-and-gear assembly includes a worm and a worm gear engaged therewith. The lash-eliminating device comprises a base, a frame, a motor, and a biasing member. The worm gear is disposed on the base. The frame is disposed on the base in a rotatable manner. The motor is disposed in the frame, and includes an output shaft. The output shaft is connected to the worm. The biasing member is disposed on the base in a manner such that the biasing member abuts the frame. Thus, when the worm is rotated by the motor via the output shaft so as to rotate the worm gear, the frame is rotated by the biasing member so that the worm is moved relative to the worm gear to eliminate a lash between the worm and the worm gear.
