2.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.

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.

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.

7.WO/2017/023440LIGHT-EMITTING DEVICE

WO - 09.02.2017

Clasificación Internacional H01L 51/52 Nº de solicitud PCT/US2016/039082 Solicitante APPLE INC. Inventor/a KIM, KiBeom

An organic light-emitting diode may have transparent electrodes. An organic emissive layer may be interposed between the electrodes. The emissive layer may emit light in response to current injected from the electrodes. The organic light-emitting diode electrodes may cover an electrode area. The electrode area may be square or may have other shapes. To enhance brightness uniformity, portions of the electrodes in a peripheral region (H1, H2) of the electrode area may have higher sheet resistances than a central portion of the electrode area. The electrode area may be square and may have four corners. The higher sheet resistances may be associated with regions of the electrode area adjacent to the corners. Elevated sheet resistances may be produced by forming the electrodes with different thicknesses in different areas or by providing supplemental conductive structures (104) in selected areas of the electrode area.

9.WO/2017/019725SYSTEM AND METHOD FOR LIGHT AND IMAGE PROJECTION

WO - 02.02.2017

Clasificación Internacional G06K 9/00 Nº de solicitud PCT/US2016/044165 Solicitante APPLE INC. Inventor/a POTTER, Daniel E.

Aspects of the present disclosure involve systems, methods, devices, and the like, for controlling the projection of an array of lights or an image from a headlight of a vehicle in response to information provided by one or more sensors or user inputs. The projection may be utilized to highlight an object in or near the path of travel of a vehicle. In another example, the headlight may be controlled to adjust the contrast across the field of view of the headlight. In addition, the system may project one or more images onto an object or surface either in the path of the vehicle or within the field of view of the headlight, projecting a "next step" in a series of navigation instructions onto the road, and/or projecting an indication of a movement of the vehicle to warn people around the vehicle of the movement of the vehicle. One or more visual effects may also be incorporated into the system to enhance the visibility of objects.

10.WO/2015/020663SCULPTED WAVEFORMS WITH NO OR REDUCED UNFORCED RESPONSE

WO - 12.02.2015

Clasificación Internacional G06F 3/01 Nº de solicitud PCT/US2013/054220 Solicitante APPLE INC, Inventor/a WESTERMAN, Wayne C.

An electronic device may generate a canceling component that reduces or eliminates the unforced response for a base waveform applied to a component haptic output device of the electronic device. The electronic device may create a sculpted waveform that has no or reduced unforced response and may store the created sculpted waveform. The electronic device may apply the sculpted waveform to the component haptic output device. In one embodiment, a space of at least possible parameters may be defined. Canceling component corresponding to points in the space may be iteratively tested. A heat map may be generated based on the unforced response cancellation or elimination of the canceling components corresponding to the points. Based at least on the heat map, a canceling component may be selected. A sculpted waveform may then be generated by combining the base waveform with the canceling component.
