Patent number: 11880111Abstract: A pair of eyeglasses may include one or more adjustable lenses that are each configured to align with a respective one of a user's eyes. The adjustable lenses may each include electrically modulated optical material such as one or more liquid crystal cells, each having a phase profile that is adjusted using patterned electrodes. Analog voltages may be provided to the patterned electrodes through variable-resistance conductive paths that are each coupled to a subset of the patterned electrodes. Digital voltage selection circuitry may be used to select which analog voltage to apply to each of the variable-resistance conductive paths from a predetermined set of analog voltages that are generated off of the lens. The digital voltage selection circuitry may include an array of multiplexers, each of which selects a desired voltage based on control signals received from digital control circuitry such a shift register and/or a decoder.Type: GrantFiled: February 22, 2021Date of Patent: January 23, 2024Assignee: Apple Inc.Inventors: Patrick R.

Publication number: 20210041705Abstract: 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.Type: ApplicationFiled: October 28, 2020Publication date: February 11, 2021Inventors: James E.

Patent number: 10488651Abstract: Metasurfaces comprise an array of meta-atoms in a stretchable polymer. The dimensions and shapes of the meta-atoms and the spacing are varied to obtain desired optical properties. Any optical wavefront, for different wavelengths, illumination angles, and polarization states can be designed with proper design of the meta-atoms. As the metasurface is stretched, the distance between the meta-atoms changes, modifying the optical response, while the dimensions of the meta-atoms remains constant.Type: GrantFiled: April 9, 2018Date of Patent: November 26, 2019Assignee: CALIFORNIA INSTITUTE OF TECHNOLOGYInventors: Seyedeh Mahsa Kamali, Ehsan Arbabi, Amir Arbabi, Yu Horie, Andrei Faraon
