  • Patent number: 10078257
    Abstract: The invention discloses an oscillating lens module and a projector. The oscillating lens module includes a frame, a first coil, a lens, and a second coil. The first coil and the second coil are connected to the frame and located in a magnetic field, wherein the first coil and the second coil are adapted to be electrified and to oscillate about a first axis and a second axis respectively via the magnetic field. The lens is connected to the first coil, wherein the lens is adapted to oscillate along with the first coil. An oscillation phase of the second coil is opposite to an oscillation phase of the first coil, such that forces applied on the frame by the first coil and the second coil are counterbalanced, so as to prevent the oscillating lens module from over vibrating which makes projection images shake and makes noise.

  • Publication number: 20180149533
    Abstract: The present invention provides an axial rotary type torque sensor comprising a planetary gear set disposed along a central axis between an input shaft and an output shaft. The input shaft drives the sun gear which meshes with planetary gears, and the planetary gears mesh with the ring gear of the planetary gear set to rotate along the circumference of the central axis. The ring gear is connected with a plurality of strip-like beams. At least one strain gauge is attached to the beams. One ending portion of the beam is fixed and the other ending portion is used for bearing a tangential force applied on the ring gear to generate a deformation at a rotation direction of a circumference. A strain gauge which senses the strain of the deformation used as a torque sensing value between the input shaft and the output shaft, thereby improving the poor sensing accuracy and sensitivity of the conventional torque sensors and solving the problem that the radial volume cannot be effectively reduced.
