Abstract: An augmented reality display alternates between displaying color frames and alpha frames to generate composite images for transparency control. A display processor includes two sets of buffers, each set including a color frame buffer and an alpha frame buffer. One set of buffers is used to provide data to the display while new video data is being written into the other set of buffers. The display processor switches which set of buffers is providing data and which set of buffers is having new video data written into them. By switching the alpha and color frame buffers in sets, a pair of color frame buffer and alpha frame buffer are always the current set of buffers to provide data as the output. If a frame drop occurs and the next color frame or alpha frame is not ready, the set of buffers is not switched to avoid disturbing flashing visual artifacts.

Abstract: Interface circuits that may utilize a limited number of pins to detect a presence of an accessory, determine whether the accessory can provide or receive power, communicate with the accessory regarding at least that transfer of power, and transfer power accordingly. One example may provide detection circuitry for a host that may detect the presence of a pull-down resistor on a data pin of an accessory. The pull-down may indicate that a power consuming accessory has been connected. This example may detect the presence of power on a power pin. The presence of the power on the power pin may indicate that a power providing accessory has been connected.

Abstract: An augmented reality (AR) mirror system is described. In an example, the AR mirror system includes a sensor, a display device, a semi-reflecting surface, a processing system, and computer-readable storage media having instructions stored thereon. The instructions are executable by the processing system to cause display of augmented reality (AR) digital content by the display device to be simultaneously viewable with a reflection of a physical object.

Abstract: Methods, circuits, and apparatus to distribute power among devices in an electronic system where a device may receive power from more than one source, may have a bidirectional power connector, or both. One example may resolve conflicts when an electronic device receives power from more than one source. In this example, the device may determine which source may provide the most power, and may select to receive power from the power source that may deliver the most power. Other examples may have a preference to receive power from a particular source or via a specific connector. Other examples may switch from receiving power over a first connector to providing power over the first connector, while others may receive and provide power over different connectors at the same time. Another may be connected to a battery, and may draw power from the battery or not depending on the type of battery.

Abstract: A system such as a vehicle system may include a window. The window may have glass layers and an interposed polymer layer. Signal paths that contact the polymer layer may be formed within the window. The signal paths may be electrical signal paths formed from wires or patterned conductive traces. The conductive traces may be portions of an infrared-light-blocking layer formed from a conductive film or may be patterned from other conductive thin-film layers. The signal paths may include optical waveguides formed from optical fibers embedded in the polymer or transparent thin-film layers on the glass layers or other substrates. Openings may be formed in the glass layers to allow signal paths to pass to an electrical component. The electrical component may also be wirelessly coupled to the signal paths.

Abstract: Embodiments disclosed herein relate generally to a stylus for texture capture. The stylus includes an image sensing and capture device to permit a surface to be scanned using the stylus and an image may be stored and displayed on an electronic device to represent the texture of the scanned surface.
