Abstract: Methods and systems are disclosed for joint scheduling of wireless and video activities.

Streaming of the video data to a display device may be initiated such that for each frame of a set of frames represented in the video data: the frame is encoded, transmitted, and the set of network-calibration events is initiated according to the schedule. Each of the network-calibration event being configured to be initiated during a non-encoding time interval during which none of the set of frames are being encoded.

Abstract: Two different wireless protocols can be used for ranging between a mobile device and an access control system (e.g., a vehicle). The first wireless protocol (e.g., Bluetooth®) can be used to perform authentication of the vehicle and exchange ranging capabilities between a mobile device (e.g., a phone or watch) and the vehicle. The second wireless protocol (e.g., ultra-wideband, UWB) can use a pulse width that is less than a pulse width used by the first wireless protocol (e.g., 1 ns v. 1 ?s). The narrower pulse width can provide greater accuracy for distance (ranging) measurements.

Abstract: An optical prism that includes an interlock structure that precisely couples to a complementary structure of a refractive lens. For precision, the interlock structure may be formed at the same time and using the same technique as the optical surface of the prism. The interlock structure provides high accuracy when assembling a folded lens system by precisely aligning the object side optical surface of the lens with the image side optical surface of the prism so that the optical axis is centered in the lens. The prism may have refractive power. A portion of the object side surface may be coated with an opaque material to provide an aperture stop at that surface.

Abstract: Application processes executing on a mobile device can interact with interfaces (e.g., routines of an application programming interface) exposed on that mobile device in order to establish a wireless connection either directly to a network (e.g., the Internet) or directly to an intermediary device through which the application processes can then communicate with the network indirectly. The intermediary device can communicate with the network on behalf of the mobile device. The application processes can remain unaware, in either case, of whether the interfaces are communicating with the network through the intermediary device or not. The interfaces can insulate the application processes from that fact. The use of the intermediary device can be transparent to the application processes, such that the manner in which the application processes transmit and receive data using the interfaces remains constant regardless of whether the intermediary device is involved.

Abstract: Systems, methods, and computer readable media to improve the operation of detecting contact between a finger or other object and a surface are described. In general, techniques disclosed herein utilize a depth map to identify an object and a surface, and a classifier to determine when the object is touching the surface. Unlike the prior art, a measure of the object's “distance” is made relative to the surface and not the camera(s) thereby providing some measure of invariance with respect to camera pose. The object-surface distance measure can be used to construct an identifier or “feature vector” that, when applied to a classifier, generates an output indicative of whether the object is touching the surface. The classifier may be based on machine learning and can be trained off-line before run-time operations are commenced. In some embodiments, temporal filtering may be used to improve surface detection operations.

Abstract: A two-step process to determine the layout of an electronic document such as a webpage or an article is provided. The electronic document is selected from a summary page that displays summaries of several documents. In the first pass, an image of the selected document is identified in the summary page and the end of the image is marked as a target location for doing a partial layout. A partial layout that includes a location for the image is then determined and stored. The image is animated to the determined location. In the second pass, while the image is being animated, a full layout is determined for the document. The full layout uses the stored results of the first pass and generated the layout from the target location to the end of the document.

Abstract: Systems and methods are provided for differential sensing (DS), difference-differential sensing (DDS), correlated double sampling (CDS), and/or programmable capacitor matching to reduce display panel sensing noise. An electronic device may include one or more processors and an electronic display. The one or more processors may generate image data and adjust the image data based at least in part on display sensing feedback.

This reference signal may provide a common mode noise reference, which is removed by the differential sensing and thereby enhances a quality of the sensed electrical value of the pixel.
