  • Publication number: 20210342016
    Abstract: Embodiments of present disclosure relates to a wheel assembly that can be used with mouse or other input device. The wheel assembly includes a wheel, a magnet for generating a magnetic field, and at least three magnetic sensors for sensing an absolute angular position of the wheel. The magnet coupled to the wheel and operable to rotate with a rotation of the wheel. The at least three magnetic sensors are arranged within a plane that is located in a predetermined distance from the magnet and substantially parallel to a main direction of the magnetic field generated by the magnet. Compared to the conventional sensors that measure the relative position of the wheel, such multiple magnetic sensors based wheel assembly enables a direct absolute angular position measurement.

  • Patent number: 10459543
    Abstract: Described are examples of an input device having a wheel with a plurality of teeth, where at least the plurality of teeth are composed of a ferrous or magnetic material. A magnet is disposed to provide a first magnetic field that attracts the ferrous or magnetic material of the plurality of teeth to provide a detent action when moving the wheel from a first position to a second position. A magnet sheet is disposed to provide a second magnetic field that causes the magnet sheet to deform based on magnetic attraction to the ferrous or magnetic material of the plurality of teeth when moving the wheel from the first position to the second position. A strain sensor coupled to the magnet sheet can detect a strain caused by deformation of the magnet sheet, and provide an electronic signal indicating the strain.

  • Patent number: 10156318
    Abstract: The exemplary non-limiting embodiments described herein provide a display suspension device and related display device. In at least one embodiment, the display suspension device includes: a vertical slider, which is connected to a display so as to guide the display to slide in the vertical direction; a suspension part, with one end of the suspension part joined with the vertical slider and the other end connected to a suspension point; an air spring, which is located on the suspension part and used to retain the location of the vertical slider when the vertical slider stops sliding; a movable pulley, a rotation shaft of which is connected to a piston rod of the air spring; and a cable, which winds around the movable pulley, with one end of the cable connected to the suspension part and the other end connected to the vertical slider.
