    Abstract: Systems and methods for determining a location of a wearable electronic device are disclosed. In some aspects, the device includes a position acquisition device and an accelerometer. A hardware processor included in the device may be configured to generally maintain the position acquisition device in a low power state to save power. When a video or image is captured, it may tag the video or image with first location information. Given the inoperative position acquisition device, a current location may not be known. In some aspects, in response to a need for location information, measurements from an accelerometer may be stored. The position acquisition device may also be transitioned to an operative state, and after some time delay, a second location determined. In some aspects, the location of the capture may then be obtained based on the acceleration measurements and the second location.

    Abstract: Systems and methods for device handshaking are described. Embodiments for client device and associated wearable device initiated handshaking are described. In certain embodiments, a device such as wearable camera eyeglasses having both high-speed wireless circuitry and low-power wireless circuitry communicates with a client device. The low-power wireless circuitry is used for signaling and to manage power on handshaking for the high-speed circuitry in order to reduce power consumption. An analysis of a high-speed connection status may be performed by a client device, and used to conserve power at the glasses with signaling from the client device to indicate when the high-speed circuitry of the glasses should be powered on.

    Abstract: System, methods, devices, and instructions are described for fast boot of a processor as part of camera operation. In some embodiments, in response to a camera input, a digital signal processor (DSP) of a device is booted using a first set of instructions. Capture of image sensor data is initiated using the first set of instructions at the DSP. The DSP then receives a second set of instructions and the DSP is programmed using the second set of instructions after at least a first frame of the image sensor data is stored in a memory of the device. The first frame of the image sensor data is processed using the DSP as programmed by the second set of instructions. In some embodiments, the first set of instructions includes only instructions for setting camera sensor values, and the second set of instructions includes instructions for processing raw sensor data into formatted image files.

    Abstract: Systems, methods, devices, media, and instructions are described for fast video sensor adjustment. In one embodiment, a portable electronic device with image capturing capabilities automatically captures a first plurality of frames upon selection of an input button while sensors of the device are determining camera settings for the environment. The first plurality of frames are captured using different automatic bracketing settings. Once the camera settings are determined, a second plurality of images are captured using the determined camera settings. One or more of the first plurality of images are used along with the second plurality of images for a video file. The one or more images may be selected based on a match between certain of the automatic bracketing settings and the final camera settings. A server computer may then aggregate settings from different devices to provide updated automatic bracketing settings to various devices.

    Abstract: Embodiments for device pairing using optical codes are described. One embodiment is a wearable device with an image sensor configured to capture an image including a first optical code from a first host device. The wearable device decodes the first optical code, and in response to the first optical code, initiates broadcast of a pairing advertisement. The host device displays a second optical code in response to the pairing advertisement, and the wearable device captures and processes the second optical code to determine a host pairing advertisement code. The wearable device then, in response to the second optical code, initiate broadcast of a second pairing advertisement including the host pairing advertisement code. In various embodiments, a secure wireless channel is then established and used for further secure communications.
