2.WO/2023/003854OPTICAL SYSTEMS WITH HOLOGRAPHIC GRATINGS

WO - 26.01.2023

Clasificación Internacional G02B 5/18 Nº de solicitud PCT/US2022/037560 Solicitante APPLE INC. Inventor/a WANG, Yifei

An electronic device may have a display system. The display system may include a waveguide, an input coupler, and a surface relief grating (SRG) structure. The SRG structure may be formed from a high-index material that includes titanium dioxide nanoparticles. To increase the refractive index of the high-index material, the ratio of the size of the nanoparticle core to the size of the capping layer may be increased. The high-index material may also include nanoparticles of different sizes to increase the packing density of the nanoparticles. The SRG structure may be depth modulated in a lateral direction to maximize efficiency. The SRG structure may include slanted ridges covered by an encapsulant. The SRG structure may include a blazed grating with ridges that are covered by a coating and encapsulated by an encapsulant.

3.WO/2022/216459DISPLAYS WITH VIEWER TRACKING FOR VERTICAL PARALLAX CORRECTION

WO - 13.10.2022

Clasificación Internacional H04N 13/305 Nº de solicitud PCT/US2022/021558 Solicitante APPLE INC. Inventor/a HUANG, Yi-Pai

An electronic device may include a stereoscopic display with a plurality of lenticular lenses that extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may have different viewing zones that account for horizontal parallax as a viewer moves horizontally relative to the display. The display may be dimmed globally based on the detected vertical position of the viewer. The magnitude of dimming applied to the display may increase with increasing deviation of the viewer from a baseline viewing angle. The display may render content that compensates for the real-time vertical position of the viewer. Another option for the stereoscopic display is to include a lens film that has an array of lenses. Each lens in the array of lenses spreads light in the horizontal direction and the vertical direction.

4.WO/2018/034990WIRELESS CHARGING ALIGNMENT SYSTEMS

WO - 22.02.2018

Clasificación Internacional B60L 11/18 Nº de solicitud PCT/US2017/046589 Solicitante APPLE INC. Inventor/a ALVES, Jeffrey, M.

A system such as a vehicle may have control circuitry that controls a steering and propulsion system. The control circuitry may use the steering and propulsion system to park the vehicle in a parking space. Wireless power may be transferred from a wireless power transmitter in the parking space to a wireless power receiver coupled to a vehicle body in the vehicle. The control circuitry may use sensors to make sensor measurements during parking events. The control circuitry may also gather information on wireless power transfer efficiency. Historical vehicle-to-wireless-power-transmitter alignment information may be updated based on the sensor measurements and corresponding wireless power transfer efficiency measurements and may be used to park the vehicle in an optimal location during subsequent parking events. Vehicle parking position may be intentionally varied over a series of parking events to gather additional alignment information.

5.WO/2015/047410WATERPROOF SPEAKER MODULE

WO - 02.04.2015

Clasificación Internacional H04R 1/44 Nº de solicitud PCT/US2013/062696 Solicitante APPLE, INC. Inventor/a SALVATTI, Alexander, V.

A waterproof speaker module may include a membrane formed from at least one waterproof and elastic material and a supporting structure. The membrane may include an outer surface, an inner surface, and at least one concave region that is indented toward the inner surface. The supporting structure may be coupled to the membrane and include a support structure that mates with the concave region of the membrane when the speaker is subjected to a hydrostatic load. When the speaker is not subjected to a hydrostatic load, the support structure may contact the concave region. In this way, the membrane may be resistant to tearing or rupture due to hydrostatic load.

6.WO/2017/052727LIGHT SENSING DISPLAY

WO - 30.03.2017

Clasificación Internacional G09G 3/3233 Nº de solicitud PCT/US2016/042829 Solicitante APPLE INC. Inventor/a LIN, Hung Sheng

A display may have an array of pixels. The pixels may contain light-emitting diodes. When it is desired to use the display to operate as a light sensor, some of the light-emitting diodes may be forward biased to emit light while some of the light-emitting diodes are reversed biased to detect the emitted light after the emitted light has reflected from an external object. During light sensing operations, one or more areas of the display may be temporarily deactivated so that the light-sensing pixels may measure the reflected light. Vertical lines may serve both as data loading lines and as current sensing lines. Currents may be sensed during drive transistor current compensation and during light sensing. The vertical lines may load signals into the pixels that forward bias the light-emitting diodes to emit light when it is desired to display images for a user.

7.WO/2013/165601MOMENT COMPENSATED BENDING BEAM SENSOR FOR LOAD MEASUREMENT ON PLATFORM SUPPORTED BY BENDING BEAMS
