Abstract: Eyewear including a sensor integrated into frame of eyewear. In one example, the sensor comprises a strain gauge, such as a metallic foil gauge, that is configured to sense and measure distortion of the frame when worn by a user and under different force profiles, by measuring a strain in the frame when bent. The measured strain by strain gauge is sensed by a processor, and the processor performs dynamic calibration of image processing based on the measured strain. The distortion measured by the strain gauge is used by the processor to correct calibration of the cameras, and the displays.

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: 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: 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.
