Abstract: An electronic device may include wireless circuitry with a processor, a transceiver, an antenna, and a front-end module coupled between the transceiver and the antenna. The front-end module may include one or more radio-frequency amplifiers for amplifying a radio-frequency signal. The radio-frequency amplifier may include input transistors cross-coupled with capacitance neutralization transistors and/or coupled to cascode transistors. One or more n-type gain adjustment transistors may be coupled to source terminals of the capacitance neutralization transistors. One or more p-type gain adjustment transistors may be coupled to source terminals of the cascode transistors. One or more processors in the electronic device can selectively activate one or more of the gain adjustment transistors to reduce the gain of the radio-frequency amplifier without degrading noise performance and without altering the in-band frequency response of the radio-frequency amplifier.

Abstract: This relates to systems and processes for using a virtual assistant to arbitrate among and/or control electronic devices. In one example process, a first electronic device samples an audio input using a microphone. The first electronic device broadcasts a first set of one or more values based on the sampled audio input. Furthermore, the first electronic device receives a second set of one or more values, which are based on the audio input, from a second electronic device. Based on the first set of one or more values and the second set of one or more values, the first electronic device determines whether to respond to the audio input or forego responding to the audio input.

Abstract: Depth sensing apparatus includes a radiation source, which emits a first array of beams of light pulses through a window toward a target scene. Objective optics image the target scene onto a second array of sensing elements, which output signals indicative of respective times of incidence of photons. A first calibration, which associates the beams in the first array with respective first locations on the second array onto which the beams reflected from the target scene are imaged, is used in processing the signals in order to measure respective times of flight of the light pulses. A second calibration indicates second locations on which stray radiation is incident on the second array due to reflection of the beams from the window. Upon detecting a change in the second locations relative to the second calibration, the first calibration is corrected so as to compensate for the detected change.

Abstract: A system comprises an encoder configured to compress and encode data for a three-dimensional mesh using a video encoding technique. To compress the three-dimensional mesh, the encoder determines sub-meshes and for each sub-mesh: texture patches and geometry patches. Also the encoder determines patch connectivity information and patch texture coordinates for the texture patches and geometry patches. The texture patches and geometry patches are packed into video image frames and encoded using a video codec. Additionally, the encoder determines boundary stitching information for the sub-meshes. A decoder receives a bit stream as generated by the encoder and reconstructs the three-dimensional mesh.

Abstract: Managing the display of an electronic device includes receiving an instruction to activate an enhanced state of the display and obtaining a current operating value of the display operating in a base state. An enhanced operating value is determined for the display based on the current operating value and a power budget allocated to the display. The enhanced operating value may be greater than the current operating value and is less than a maximum operating value of the display in the enhanced state. The display is instructed to operate in the enhanced state at the enhanced operating value.

Abstract: A camera module with sticky epoxy and method for dislodging particles from a corresponding IR filter. Particles, formed during manufacture or use of the camera, may accumulate in the camera (e.g., on an infrared filter) causing blemishes in camera images. A sticky epoxy with characteristics for attracting and capturing particles is located in the camera. The epoxy may be located in a gap between a substrate and an outside edge of an infrared filter coupled to the substrate. The epoxy and the gap may surround the infrared filter and the epoxy may also be located on other surfaces of the camera. A process for loosening particles from the infrared filter includes driving an actuator that moves the substrate/infrared filter assembly (perhaps striking a base assembly) to loosen the particles from the infrared filter such that the particles are moved to, and trapped by, the epoxy.

Abstract: Keyboards and other electronic input devices have a key or keys with glyphs that are invisible to an unaided human eye in a first condition, such as when an underlying display attached to the key is not emitting light. The glyphs are visible through the key or keys when the display emits light. A one-way visibility layer or structure obscures the visibility of the display when viewed from above, but when the display emits light, the light penetrates through the one-way visibility layer, such as by passing through an array of microperforations in the key, and is visible to an onlooker.

Abstract: Some embodiments relate to sharpening segments of an image differently based on content in the image. Content based sharpening is performed by a content image processing circuit that receives luminance values of an image and a content map. The content map identifies categories of content in segments of the image. Based on one or more of the identified categories of content, the circuit determines a content factor associated with a pixel. The content factor may also be based on a texture and/or chroma values. A texture value indicates a likelihood of a category of content and is based on detected edges in the image. A chroma value indicates a likelihood of a category of content and is based on color information of the image. The circuit receives the content factor and applies it to a version of the luminance value of the pixel to generate a sharpened version of the luminance value.

Abstract: Touch screens with ultra-thin stack-ups can provide for a lower profile device, can improve the optical image on the display by reducing the display to cover glass distance, and can reduce the weight of the device. In some examples, the thickness of the touch screen stack-up can be reduced and/or the border region reduced, by removing the flex circuit connection from the stack-up. A flexible substrate can be used to enable routing of touch electrodes to touch circuitry. In some examples including a shield layer, the thickness of the touch screen stack-up can be reduced by routing the shield layer to a shield electrode on the touch sensor panel. The shield layer can then be routed to touch sensing circuitry via the flexible substrate. In some examples, the touch sensor panel or a portion of thereof can be integrated with the polarizer.
