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 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: Techniques involve determining a target identifier of an operation command if a type of the operation command is determined to be a target type, the target type indicating that the operation command is a command for acquiring data. The techniques further involve executing the operation command to acquire a target data block if it is determined that the target identifier does not exist in a historical mapping relationship between stored data blocks and identifiers of historical operation commands for the stored data blocks. The techniques further involve storing the target data block and a target mapping relationship between the target data block and the target identifier in a storage space for storing the stored data blocks and the historical mapping relationship. Accordingly, different types of commands can be quickly distinguished, thereby reducing the time for processing commands of a target type, reducing the bandwidth consumed, and improving processing efficiency.

Abstract: A leak indicator includes a substrate comprising a permeable material with an immobilized reactant embedded in the substrate at a fixed location and a mobile reactant disposed at an initial location on the substrate. The initial location of the mobile reactant is spaced apart from the fixed location of the immobilized reactant. The mobile reactant is transported through the substrate by water to the fixed location of the immobilized reactant. The mobile reactant and the immobilized reactant interact to indicate a leak when the mobile reactant reaches the immobilized reactant.
