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.

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.

10.WO/2016/048741THREE-DIMENSIONAL FABRIC WITH EMBEDDED INPUT-OUTPUT DEVICES

WO - 31.03.2016

Clasificación Internacional D03D 1/00 Nº de solicitud PCT/US2015/050373 Solicitante APPLE INC. Inventor/a

Three-dimensional weaving, knitting, or braiding tools may be used to create three-dimensional fabric (24) with internal pockets (56). The pockets (56) may be shaped to receive electrical components such as switch electrodes (46A, 46B) for a switch (18). The fabric (24) may have adjacent first and second layers that are interposed between the switch electrodes (46A, 46B). The switch electrodes (46A, 46B) may be biased apart using magnets (46A-1, 46B-1) or other biasing structure. In a region of the fabric (24) that overlaps the first and second switch electrodes (46A, 46B), the first and second layers of fabric may be disconnected from each other. This allows the first and second layers to pull away from each other so that the electrodes (46A, 46B) are separated by the biasing force from the biasing structure. The switch (18) can be closed by pressing the electrodes (46A, 46B) together.
