Clasificación Internacional G02B 27/01 Nº de solicitud PCT/US2022/052656 Solicitante APPLE INC. Inventor/a DHANDHANIA, Vedant A.

Electronic devices such as head-mounted electronic devices may include displays for presenting images to users. To accommodate variations in the interpupillary distances associated with different users, a head-mounted device may have left-eye and right-eye optical modules that move with respect to each other. To hide internal structures from view, the rear of a head-mounted device may be provided with a stretchable fabric cover with openings for receiving optical modules. The fabric cover may have first strands forming a warp knit layer with diamond-shaped openings and second strands that zig-zag back and forth within the diamond-shaped openings. The first strands may stretch in the warp direction, while the second strands may stretch in the weft direction. The second strands may have a fuzzy covering for hiding electrical components even as the diamond-shaped openings expand when the fabric is stretched.

An adjustable tint layer having multiple states that involve transmission of different amounts of the world light may be disposed between the bias lens and the output coupler. Different states may impart different colors and/or may impart a gradient transmission characteristic to the world light. The bias lens itself may form the adjustable tint layer. The adjustable tint layer may have a transparent electrode layer that is provided with one or more AC voltages that heat the adjustable tint layer. The adjustable tint layer may be a self-switching electrochromic device that includes a transparent solar cell.

WO - 18.04.2024

Clasificación Internacional G02B 27/01 Nº de solicitud PCT/US2022/048579 Solicitante APPLE INC. Inventor/a YOUNG, Austin S

A head-mounted device may have eyeglass lenses. Each eyeglass lens may have an optical system with inner and outer lens elements and a waveguide and light modulator between the inner and outer lens elements. The waveguide of each system may be configured to receive and guide an image from a projector. The waveguide may have a may have an output coupler configured to direct the image out of the waveguide through the inner lens element to an eye box for viewing by a user. The light modulator in each optical system may be electrically adjustable between a higher transmission state that enhances the visibility of real- world objects through the lens and a lower transmission state that dims ambient light to enhance the visibility of the image from the projector. The light modulator layer may have electrode structures that use portions of the waveguide and/or outer lens element as substrates.

5.WO/2023/091322TUNABLE LENS CONTROLLED BY AN ACTUATOR

WO - 25.05.2023

Clasificación Internacional G02B 3/14 Nº de solicitud PCT/US2022/049093 Solicitante APPLE INC. Inventor/a TOPLISS, Richard J

A head-mounted device may have a display that displays content for a user. Head- mounted support structures in the device support the display on the head of the user. A lens module in the head-mounted device may include a transparent lens element, a positioner that extends around the periphery of the transparent lens element, and an actuator that selectively shifts the positioner in a first direction. Shifting the positioner in the first direction causes the transparent lens element to be biased in a second direction that is orthogonal to the first direction at multiple points around the periphery of the transparent lens elements. The positioner may be attached to guide structures that each have a respective angled slot. Each angled slot may receive a respective tab of the transparent lens element or a respective tab of a lens shaping element that is attached to the transparent lens element.

6.WO/2023/101797HYBRID DISPLAYS

WO - 08.06.2023

Clasificación Internacional H10K 59/95 Nº de solicitud PCT/US2022/049376 Solicitante APPLE INC. Inventor/a PEDDER, James E

A hybrid display may include different display portions with different resolutions. The high resolution display portion may be positioned in a main viewing area for the viewer whereas the low resolution display portion may be positioned in a peripheral viewing area. The high resolution display portion may have a silicon backplane. The low resolution display portion may have a different type of backplane such as a thin-film transistor backplane. The different display portions may optionally share a common organic light-emitting diode layer such that light is emitted from the same plane across both display portions. The high resolution display portion may emit light through a transparent window in the low resolution display portion. A high resolution display may also be formed by separately forming a frontplane and a backplane. Conductive attachment structures such as indium bumps may be used to mechanically and electrically connect the backplane to the frontplane.

10.WO/2010/029690DISTORTION COMPENSATION AMPLIFICATION DEVICE

WO - 18.03.2010

Clasificación Internacional H03F 1/32 Nº de solicitud PCT/JP2009/004050 Solicitante HITACHI KOKUSAI ELECTRIC INC. Inventor/a HONGO, Naoki

Disclosed is a more efficient distortion compensation amplification device with a pre-distorter (1). A level detection means (11) detects a signal level. A correspondence memory means (12) outputs distortion compensation coefficients in response to the signal level. A pre-distortion execution means (13) imparts distortion having the inverse characteristics to a signal. A filter means (8) outputs the distorted signal component from a feedback signal of the output of an amplifier (4). A correspondence acquisition means (14) updates the coefficients for training to construct a function which imparts the inverse characteristics so that the distorted signal component becomes smaller. Orthogonal polynomials are used in the function which imparts the inverse characteristics. Each orthogonal function is the sum of the products of the functions of the input signal and the parameters. The parameter values are set so that the orthogonal functions are mutually orthogonal when the function, which is obtained by applying a filter having the same characteristics as the filter means (8) to the function of the input signal, is replaced by a function of the input signal constructed by the orthogonal functions.
