  • Patent number: 11749024
    Abstract: The present invention provides a graphics processing method and an eye-tracking system capable of providing adaptive foveated rendering. If the system latency of a current application is greater than the threshold latency under the existing rendering parameter, adjusted rendering parameters are provided by adjusting the existing rendering parameters according to the system latency of the current application. Foveated images may thus be generated according to the adjusted rendering parameters in order to maintain the balance of resolution quality and rendering performance.

  • Publication number: 20170013952
    Abstract: A touch-control flashing toothbrush comprises a hollow brush handle and a control circuit board. The hollow brush handle has a brush head at one end and a light-permeable handle member at another end. The control circuit board is arranged inside the hollow brush handle and includes a control circuit electrically connected with a light emitting element, two electric-conduction contacts, and a battery assembly. The battery assembly supplies power to the other elements. The electric-conduction contacts are exposed on the surface of the hollow brush handle. Once two electric-conduction contacts are touched simultaneously, voltage of the battery assembly is conducted to the control circuit. Then, the control circuit controls the light emitting element to emit light projecting to exterior through the light-permeable handle member. The touch-control flashing toothbrush is triggered to emit light by touch, interesting children and encouraging them to keep oral health.
