  • Patent number: 11914831
    Abstract: Techniques are described for discrete-time self-capacitor sensing in a touch panel. The self-capacitor manifests a detectably different capacitance based on presence or absence of a local touch event on the touch panel. In a first time phase, embodiments charge a self-capacitor and initialize a ramp bias generator. In a second time phase, embodiments discharge the self-capacitor with a ramp-controlled current source that is biased by the ramp bias generator to produce a discharge current that transitions from high at the beginning of the second time phase to low at the end of the second time phase. By the end of the second phase, the remaining charge in the self-capacitor depends on presence or absence of a local touch event. Some embodiments convert the remaining charge to an amplified sense output for readout.

  • Patent number: 11914767
    Abstract: In a see-through waveguide-based HMD device configured to display holographic virtual images within a field of view (FOV) of a device user, a glint-based eye tracker illumination system provides infrared (IR) point sources at known locations having a predetermined angular distribution using optical components—including input and output couplers and diffusers—on a waveguide that is located in front of the user's eyes. An input coupler couples light from an IR source into the illumination system waveguide which is propagated to one or more output couplers. Separate diffuser elements aligned with the output couplers distribute the out-coupled IR light into a deterministic range of divergent angles to function as point sources for eye tracker glints. Various illustrative illumination system waveguide architectures are disclosed in which the optical components can be disposed on the same or opposite sides of the waveguide in dual-layered and dual-sided arrangements.

  • Patent number: 11892629
    Abstract: Virtual reality (VR) displays are computer displays that present images or video in a manner that simulates a real experience for the viewer. In many cases, VR displays are implemented as head-mounted displays (HMDs) which provide a display in the line of sight of the user. Because current HMDs are composed of a display panel and magnifying lens with a gap therebetween, proper functioning of the HMDs limits their design to a box-like form factor, thereby negatively impacting both comfort and aesthetics. The present disclosure provides a different configuration for a VR display which allows for improved comfort and aesthetics, including specifically at least one coherent light source, at least one pupil replicating waveguide coupled to the at least one coherent light source to receive light therefrom, and at least one spatial light modulator coupled to the at least one pupil replicating waveguide to modulate the light.
