  • Patent number: 11875504
    Abstract: An animation system wherein a machine learning model is adopted to learn a transformation relationship between facial muscle movements and skin surface movements. For example, for the skin surface representing “smile,” the transformation model derives movement vectors relating to what facial muscles are activated, what are the muscle strains, what is the joint movement, and/or the like. Such derived movement vectors may be used to simulate the skin surface “smile.”.

  • Patent number: 11870451
    Abstract: A frequency synthesizer employs a combination of a low divide ratio divider phase-locked loop (PLL) and a wide band, on-chip voltage-controlled oscillator (VCO). To reduce phase noise, low divide ratio phase detection is employed. By using the off-chip PLL with a bank of on-chip VCOs, the frequency synthesizer may have enhanced frequency stability and avoid having to include an acquisition circuit. A separation between the PLL and VCO may reduce integer boundary spurs (IBS) eliminating or reducing a need for a filter bank and switches reducing a complexity of the frequency synthesizer.

  • Publication number: 20230230561
    Abstract: Provided is a transmissive display apparatus capable of naturally combining a projection image on a real space scene. A beam splitter splits a light incident from a real space scene into first and second portions. An image sensor generates a real space image according to the second portion of the incident light. A light modulator passes at least a part of the first portion of the incident light according to a masking image. A control and projection image generation unit selects a target object and generates the masking image based on a target object area to cause a light modulator to block a foreground of the real space scene and pass a background of the real space scene. A projection unit generates a projection image light corresponding to the projection image combines the projection image light with a part of the first portion of the incident light.

  • Patent number: 11626882
    Abstract: A wide band frequency synthesizer may include a primary phase-locked loop (PLL) to receive a signal that include a local signal and a VCO signal mixed together and to generate the tuning voltage based on a phase comparison of the local signal and the VCO signal. The local signal may be obtained from a reference signal through frequency multiplication. If the primary PLL fails to lock onto an output frequency, a secondary PLL (acquisition circuit) may be switched in performing a phase comparison between the reference signal and the VCO signal to generate the tuning voltage. The secondary PLL may then provide the tuning voltage to an output of the primary PLL.

  • Patent number: 11443473
    Abstract: An animation system wherein a machine learning model is adopted to generate animated facial actions based on parameters obtained from a live actor. Specifically, the anatomical structure such as a facial muscle topology and a skull surface that are specific to the live actor may be used. A skull surface that is specific to a live actor based on facial scans of the live actor and generic tissue depth data. For example, the facial scans of the live actor may provide a skin surface topology of the live actor, based on which the skull surface underneath the skin surface can be derived by “offsetting” the skin surface with corresponding soft tissue depth at different sampled points on the skin surface.
