    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.

    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: Eyewear including a projector having a variable feedback loop controlling a forward current delivered to a colored light source. The colored light source is configured to generate a colored light beam to generate a displayed image. The variable feedback loop in one example has a variable resistance to selectively generate a high brightness image when the eyewear is operated outside, or in a high ambient light setting, and to selectively generate a nominal brightness image when the eyewear is operated inside. A controller selectively controls the drive current delivered to the colored light source to control the brightness mode of the image.

    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.
