    Abstract: Examples include a wearable device having a frame, a temple and onboard electronics components. The frame can optionally configured to hold one or more optical elements. T temple can optionally connected to the frame at a joint such that the temple is disposable between a collapsed condition and a wearable condition in which the wearable device is wearable by a user to hold the one or more optical elements within user view. The onboard electronics components can be carried by at least one of the frame and the temple and can include a first antenna configured for cellular communication carried by the frame and a second antenna configured for cellular communication carried by one of the frame or the temple.

    Abstract: Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. Performance of such devices is improved with reduced time to first fix of location operations in conjunction with low-power operations. In one embodiment, low-power circuitry manages high-speed circuitry and location circuitry to provide location assistance data from the high-speed circuitry to the low-power circuitry automatically on initiation of location fix operations as the high-speed circuitry and location circuitry are booted from low-power states. In some embodiments, the high-speed circuitry is returned to a low-power state prior to completion of a location fix and after capture of content associated with initiation of the location fix. In some embodiments, high-speed circuitry is booted after completion of a location fix to update location data associated with content.

    Abstract: Methods and systems are disclosed for detecting whether a wearable device is being worn by a user. The system transmits a radio signal from a first communication device of a wearable device to a second communication device of the wearable device and measures a signal strength associated with the radio signal received by the second communication device. The system compares the signal strength to a threshold value and generates an indication of a wear status associated with the wearable device based on comparing the signal strength to the threshold value.

    Abstract: Eyewear device including two system on a chip (SoC) that share processing workload. The SoCs communicate with each other using a low-power bridge, e.g., a mobile industry processor interface (MIPI) bridge including a display serial interface (DSI) to camera serial interface (CSI) bridge. The MIPI bridge converts DSI images from one SoC to CSI images, and also communicates metadata. Another SoC receives and processes the CSI images. The other SoC has a buffer that receives both the CSI images and the metadata, and separates the CSI images from the metadata. The other SoC has computer vision (CV) algorithms that process the metadata, and a low-speed interface that sends metadata back to the one SoC to adjust and render a next image. The MIPI bridge may comprise a field programmable gate array (FPGA).
