  • COMPUTER MOUSE MODULE WITH AN ANGLED AND/OR SLOPED FRONT
    Publication number: 20240045512
    Abstract: A computer mouse module includes a body having a front face, a lower side, and a lower front edge portion that extends between the lower side and the front face. The lower front edge portion includes a slope between the front face and the lower side. The computer mouse module includes a movement sensor held along the slope of the lower front edge portion of the body. The movement sensor is configured to detect movement of the computer mouse module along a tracking surface at at least two angular positions of a longitudinal axis of the body relative to the tracking surface.

  • Green diode laser
    Patent number: 7003006
    Abstract: A green diode laser includes a tubular laser casing, a heat sink sealedly mounted at the laser casing, a semiconductor chip supported by the heat sink, an optical resonant cavity supported within the laser casing, including a lasing medium and an intracavity frequency doubler, an IR blocking filter inclinedly and seadedly mounted at the laser casing to optically communicate with an output facet, and a photodiode supported within the laser casing at a position that when the laser beam exits the output facet, the IR blocking filter reflects a portion of the laser beam towards the photodiode such that the photodiode is adapted for detecting the laser beam from the IR blocking filter as a feedback for controlling a power output of the green laser chip.
