  • Publication number: 20240168296
    Abstract: An electronic device may include a first bias lens that transmits world light to an output coupler on a waveguide. The output coupler may transmit the world light while coupling image light out of the waveguide. A second bias lens may transmit the world light and the image light to an eye box. A tint layer may transmit the world light towards the output coupler. The tint layer may be planar and layered onto a planar surface of the first bias lens or another lens, may be separated from the first bias lens by an air gap, may be non-parallel relative to the waveguide, and/or may be curved and separated from the first bias lens and the waveguide by air gaps. When planar, the tint layer may be provided with spacers between substrates or between the tint layer and the waveguide to maximize parallelism.

  • Publication number: 20230195265
    Abstract: Input devices can employ ultrasonic touch sensing capabilities that allow user inputs to be detected through conductive materials, such as metal enclosures. The ultrasonic touch sensing can include generation of ultrasound signals with a piezoelectric layer. The ultrasound signals can be reflected when a user or other object is in contact with a housing, and the reflected signal can be detected by the same piezoelectric layer that produced the ultrasound signal. Such a piezoelectric layer can include a piezoelectric polymer, such as polyvinylidene fluoride (PVDF). An array of electrodes distributed on opposing sides of the use of electric layer can be operated to generate ultrasound signals and detect reflected signals. Such an input device can be operated in conjunction with a conductive (e.g.

  • Patent number: 11353933
    Abstract: A notebook computer may include a display portion, a base portion, a hinge mechanism movably coupling the display portion to the base portion, an optical sensing system configured to capture an image of an object, an actuation system comprising a shape-memory alloy member coupled to the base portion and the display portion and configured to move the display portion relative to the base portion, and a processing system. The processing system may be configured to determine a target position for the display portion based at least in part on a location of the object in the image and cause the actuation system to actuate the hinge mechanism to move the display portion, relative to the base portion, from an initial position to the target position.

  • Publication number: 20210041705
    Abstract: A lens module in a head-mounted device may include a fluid-filled chamber, a semi-rigid lens element that at least partially defines the fluid-filled chamber, and at least one actuator configured to selectively bend the semi-rigid lens element. The semi-rigid lens element may become rigid along a first axis when the lens element is curved along a second axis perpendicular to the first axis. Six actuators that are evenly distributed around the periphery of the semi-rigid lens element may be used to control the curvature of the semi-rigid lens element. The semi-rigid lens element may initially be planar or non-planar. For example, the semi-rigid lens element may initially have a spherically convex surface and a spherically concave surface. A tunable spherical lens may be incorporated into the lens module to offset a parasitic spherical lens power from the semi-rigid lens element.

  • Patent number: 10630207
    Abstract: A triboelectric generator includes a first triboelectric member, which includes a first conductive layer and an insulating triboelectric material layer disposed on the first conductive layer. The triboelectric material layer includes a first material having a first position on a triboelectric series. An elastic member, disposed against the triboelectric material layer of the triboelectric member and includes a second conductive material, has an elasticity that results in the elastic member being deformed when compressed and returning to an original non-deformed shape after being compressed. The second conductive material has a second position on the triboelectric series. A first load is coupled to the first conductive layer and with the second conductive material so that when a force compresses the elastic member charges will flow between the first conductive layer and the second conductive layer through the load.

  • Publication number: 20200107569
    Abstract: The invention is an improved hypoallergenic nutritional composition consisting of fava protein, mung bean protein, rice protein, and pea protein which are blended in specified weight ratios, to achieve a high level of digestibility comparable to animal proteins such as whey protein, casein protein and egg protein. The problems of potentially allergenic soy protein compositions, solely animal-based protein compositions, incomplete amino acid profile compositions, and low levels of digestibility compositions are solved by inventing a hypoallergenic, vegetarian-based protein composition that can serve as a complete and well-balanced source of amino acids for human physiological requirements and has a high level of digestibility.
