Hover range may be adapted, for example, by adapting an antenna configuration during hover. A touch instrument may comprise multiple antennas that may be activated and deactivated, e.g., as a function of proximity Antenna configuration may increment (e.g., increase cumulative antenna size) as hover height increases and decrement (e.g., decrease cumulative antenna size) as hover height decreases. Antennas may be multi-purpose, such as being used to maintain synchronization for extended hover range and for other purposes (e.g., determining hover height, tilt, orientation, grip) and/or features (e.g., providing commands for pop-up menus).

  • Patent number: 10877606
    Abstract: Acoustic touch sensing system architectures and methods for acoustic touch sensing can be used to detect a position of an object touching a surface. Acoustic touch sensing can utilize transducers (e.g., piezoelectric) to simultaneously transmit ultrasonic waves along a surface and through a thickness of a material. The location of the object can be determined based on the amount of time elapsing between the transmission of the waves and receipt of the reflected waves. In some examples, an acoustic touch sensing system can be insensitive to water contact on the device surface, and thus acoustic touch sensing can be used for touch sensing in devices that may become wet or fully submerged in water. In some examples, techniques such as isolation and absorption of acoustic energy can be used to mitigate acoustic energy reflected by portions of the electronic device and interfere with the acoustic touch sensing operation.

  • Patent number: 10866422
    Abstract: MicroLED arrays offer a small form factor solution for the HMD image sources since they do not need a separate illumination optics. Features of the present disclosure implement a MicroLED display system that incorporate a plurality of monochrome projectors (e.g., three MicroLED projectors) to generate three monochrome images (e.g., red, blue, and green images) that are separately input into a single waveguide of the HMD and combined to form an image that is displayed to the user. By utilizing a single waveguide that includes a plurality of spatially separated input regions (e.g., a region for inputting blue light, a region for inputting red light, a region for inputting green light), the MicroLED display system of the present disclosure may reduce the form factor of the HMD device because of the reduced number of plates that may be required to combine the three monochrome images.
