  • ANTENNA IMPLEMENTATION EMBEDDED IN OPTICAL WAVEGUIDE MODULE
    Publication number: 20220121043
    Abstract: Eyewear including a see-through display including an optical waveguide module and one or more integrated antennas. In one example, the antenna is disposed on one of the non-active waveguide substrates, which non-active waveguide substrates are used as encapsulants to protect the waveguide active layer from environmental factors and do not have an active optical function in the waveguide operation. In another example, the antenna is disposed on one of the active waveguide substrate surfaces opposite another active waveguide substrate. As a result, there is a large lee-way available in patterning desired antenna shapes, length, and area on these surfaces using optically transparent, high conductivity materials. The antenna is not subject to some design constraints and compromises.

  • OPTIMIZED LASER CUTTING PROCESS FOR WAVEGUIDE GLASS SUBSTRATE
    Publication number: 20220080529
    Abstract: Cutting a wafer having devices, such as glass optical waveguides, into die by cutting into both sides of the wafer to reduce or eliminate micro-cracks and defects in the die. The wafer can be cut by simultaneously cutting the wafer from both sides using separate lasers at a controlled depth. The wafer can also be sequentially cut by cutting into one side of the wafer, flipping the wafer, and then cutting into the other side of the wafer. A processor controls the power of each laser to select the depth of each cut, such that each cut may be 50% into the wafer, or other depths such as 30% for one cut and 70% for the other cut. The wafer may be cut into the bottom surface of the wafer first, and then cut into the top surface of the wafer having the optical waveguides.

  • WAVEGUIDE WITH 2-LAYER STACK-UP
    Publication number: 20220075110
    Abstract: A lightweight stacked optical waveguide using two plastic substrates having nano-structure gratings and a single glass substrate sandwiched between them. The nano-structure gratings face each other, and are each encapsulated within the optical waveguide. The two plastic substrates are each adhesively secured to the central glass substrate rather than to each other to provide sufficient securing strength and precisely establish and maintain an air gap between the substrates. The thickness of the plastic substrates and the glass substrate are selected such that the stacked optical waveguide is lightweight, but also has sufficient drop performance. The stacked optical waveguide can be efficiently manufactured as the adhesive bonds a plastic substrate to a glass substrate.

  • Autonomously motile device with residual echo suppression
    Patent number: 11258478
    Abstract: A device capable of autonomous motion includes a residual echo suppressor for suppressing echoes caused by an output reference signal. When the device outputs audio while moving with a velocity, it may receive echoes that are Doppler-shifted due to the motion. The residual echo suppressor generates estimated residual error data based on phase-shifted reference data to account for and suppress the Doppler-shifted echoes.

  • Beamformer rotation
    Patent number: 11218802
    Abstract: A mobile device capable of capturing voice commands includes a beamformer for determining audio data corresponding to one or more directions and a beam selector for selecting in which direction a source of target audio lies. The device determines, based on data from one or more sensors, an angle through which the device has rotated. Based on the angle and one or more rotation-compensation functions, the device interpolates audio data corresponding to the one or more directions to compensate for the rotation such that the direction corresponding to the source of target audio remains selected.

  • Beam rejection in multi-beam microphone systems
    Patent number: 11175372
    Abstract: The systems, devices, and processes described herein may identify a beam of a voice-controlled device that is directed toward a reflective surface, such as a wall. The beams may be created by a beamformer. An acoustic echo canceller (AEC) may create filter coefficients for a reference sound. The filter coefficients may be analyzed to identify beams that include multiple peaks. The multiple peaks may indicate presence of one or more reflective surfaces. Using the amplitude and the time delay between the peaks, the device may determine that it is close to a reflective surface in a direction of the beam.
