    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: 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: An electronic eyewear device includes first and second systems on a chip (SoCs) having independent time bases that are synchronized by generating a common clock signal from a clock generator of the first SoC and simultaneously applying the common clock signal to a first counter of the first SoC and a second counter of the second SoC whereby the first counter and the second counter count clock edges of the common clock. The clock counts are shared through an interface between the first SoC and the second SoC and compared to each other. When the clock counts are different, a clock count of the first counter or the second counter is adjusted to cause the clock counts to match each other. The adjusted clock count is synchronized to the respective clocks of the first and second SoCs, thus synchronizing the first and second SoCs to each other.

    Abstract: A system for correcting for frame bending of an augmented reality system is provided. A combination of strain gauges and visual inertial odometry is used to determine strains in the frame. An initial model between strain gauge measurements and actual frame spatial relationships is based on finite element analysis or calibration. During an initial visual inertial odometry data calculation phase, the augmented reality system calculates bending or strains of the frame using strain data from the strain gauges mounted to the frame. Subsequent visual inertial odometry data calculations are used to generate a corrected frame model of the frame. The corrected frame model is used for calculating corrected tracking data and corrected virtual overlays that are used to generate virtual overlays used in an AR experience provided by the augmented reality system.

    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.
