    Abstract: One aspect disclosed is a method including determining a location from a positioning system receiver, determining, using a hardware processor and the location, that the location is approaching a path of direction of visual direction information, displaying the visual direction information on a display of a wearable device in response to the determining, determining, using the positioning system receiver, whether the turn of the visual direction information has been made, determining, by the hardware processor, a first period of time for display of the content data based on whether the turn of the visual direction information has been made, powering on the display and displaying, using the display, content data for the first period of time, turning off the display and the hardware processor following display of the content data.

    Abstract: Systems, computer readable medium and methods for improved boot time for autonomous drones are disclosed. Autonomous drones are disclosed that include an Off State and a Power off State. The Off State appears to a user of the autonomous drone as if the autonomous drone is off, but the Off State maintains some of the autonomous drone's state such as the operating system being loaded in a memory. The autonomous drone enters the Power off State, where all or substantially all the power is turned off, from the Off State based on a timeout or a power level of a battery dropping below a threshold level. The Off State reduces the boot time of the autonomous drone compared with the Power off State. The time reduction is often less than ten seconds, but this time is beneficial for situations where a user would like the autonomous drone to immediately perform photography.

    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: An eyewear device, method for use with an eyewear device, and a non-transient computer readable medium for detecting blood sugar levels are disclosed. The eyewear device has a frame including a first rim configured to support a first lens, a second rim configured to support a second lens, and a bridge connecting the first rim to the second rim. The bridge is configured to receive a nose of a user when the eyewear device is worn by the user. Blood sugar levels are detected by monitoring behavior of a pupil of an eye of the user with a sensor, comparing the monitored behavior with known blood sugar level behaviors, identifying a match responsive to the comparison between the monitored behavior and one of the known blood sugar level behaviors corresponding to a particular blood sugar level, and selecting the particular blood sugar level as a blood sugar level of the user.
