    Abstract: A case for an eyewear device having a conductive interface includes a housing that receives the eyewear device. A multi-purpose interface, supported by the housing, includes at least one contact arranged to couple with the conductive interface of the eyewear device when the housing receives the eyewear device. Circuitry is coupled to the at least one contact and includes a processor that detects a connection of the conductive interface of the eyewear device to the multi-purpose interface of the case. The processor performs a charging process during a charge state of the case in which an electrical charge is provided at the multi-purpose interface of the case to the eyewear device. Data is exchanged with the eyewear device during a communication state of the case.

    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).

    Abstract: Apparatuses and systems for electronic wearable devices such as smart glasses are described. The wearable device can comprise a housing, an image capture component, a locking component, and a control component. The housing defines an imaging aperture. The image capture component is coupled to the housing and aligned with the imaging aperture. The image capture component is configured to capture image data of a field of view aligned with the imaging aperture. The locking component is coupled to the image capture component. The locking component modifies a capture state of the image capture component to selectively enable image capture in response to a selection releasing the locking component. The control component is coupled to the locking component. Interaction with the control component comprises the selection releasing the locking component and triggering modification of the capture state of the image capture component.

    Abstract: A method and apparatus for monitoring a surface temperature of eyewear proximate a processor to understand the surface temperature as a function of computer instructions, such as when the computer instructions are modified during software design. A sensor is coupled to the eyewear proximate the processor, such as at a temple of the eyewear including the processor, using one or more layers of tape. A server provides instructions to the processor for execution, such as instructions of an application, which instructions vary the utilization of the processor. A testing device, such as a digital multi-meter, is coupled to the sensor, as well as the server, and displays the surface temperature as a function of the processor utilization. The surface temperature of the eyewear is monitored to ensure the surface temperature does not exceed a temperature threshold.

    Abstract: An eyewear device having an image processor operable in a camera pipeline for computer vision (CV) and in augmented reality (AR) systems. The image processor is configured to selectively control a plurality of cameras to provide images having a first resolution in the high power AR mode, and to provide the images having a second resolution in the low power CV mode. The first resolution is higher than the second resolution, and the plurality of cameras consume less power in the CV mode than the AR mode. The image processor controls the camera pipeline to process the first resolution high IQ images from the plurality of cameras to operate in the AR mode, and controls the camera pipeline to process the second resolution lower IQ images from the plurality of cameras to operate in the CV mode. Substantial power is saved by reducing the resolution of the images using downscaling in the cameras themselves in the CV mode.
