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 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: Embodiments for device pairing using optical codes are described. One embodiment is a host device with a memory and one or more processors configured to pair the host device with a wearable device. The paring involves generating and displaying an image including a first optical code, decoding decode a pairing advertisement from the wearable device, generating a second optical code, the second optical code comprising a host pairing advertisement code, and decoding a second pairing advertisement including the host pairing advertisement code. Additional embodiments involve, in response to the second pairing advertisement, establishing a communication channel between the host device and the wearable device, communicating keys between the host and wearable device, and using an application-level elliptic curve Diffie-Hellman (ECDH) exchange with the first key and the second key to establish a shared secret.

Abstract: Systems and methods for camera devices with low boot time are provided. In one example embodiment, a user input is received at an interface of a camera. In response to the user input, a low-power processor boots a image processor. The image processor then captures camera data and writes the camera data to memory before automatically powering down. In certain embodiments, a low-power wireless connection from the camera to a client device is established. Based on this connection, the low-power processor initiates boot-up of a high-speed processor and wireless communication circuitry, which is used to transmit the camera data to the client device.

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: 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.
