Abstract: Systems and methods for projecting each of a chronology of images as a sequence of images using a shifting element as part of a near-eye display system are provided for use in virtual reality, augmented reality, or mixed reality systems. In some example embodiments, a chronology of images is received by a peripheral sequencing system. The system divides each image into image portions and generates sequences of image portions to recreate the images based on arrangement data. The system then causes a high-speed display of each sequence of images such that they appear simultaneous to a viewer. In some embodiments, the projection is transmitted to a shifting optical element such as a rotating micromirror that propagates a display to a user. In some embodiments, the system further detects and corrects for image and environmental distortions.

Abstract: Various waveguides and image display systems are disclosed herein. In an example, an image display system can include an optical engine configured to generate an image and a waveguide. The waveguide can have a light in-coupling region formed along a peripheral edge of the waveguide, the light in-coupling region including a first surface with a first set of diffraction gratings, and a light exit region formed along a top surface of the waveguide, the light exit region including a second set of diffraction gratings. The first set of diffraction gratings can be configured to diffract light towards the second set of diffraction gratings, and the second set of diffraction gratings can be configured to diffract light towards the user's eye.

Abstract: Disclosed are embodiments to provide a multi-battery energy storage device. One embodiment comprises a first battery and a second battery, with a first circuit branch coupling a positive side of the first battery to a positive side of the second battery, a second circuit branch coupling a positive side of the first battery to a negative side of the second battery, a third circuit branch coupling the negative side of the first battery to the negative side of the second battery, and multiple switchable devices configured to control flow of current through corresponding branches. Other embodiments comprise other configurations and operations.

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.
