A system for a wearable personal inside-out location tracking may include a hands-free wearable display configured to display augmented reality optics among other navigation-related visualizations, a camera and an inertial sensor, and a personal computing system. The personal computing system may be configured to store information and perform computations relating to a method for personal location tracking. Such a method may include initializing a personal navigation history comprising a first-in-first-out (FIFO) queue, inserting into the FIFO queue a waypoint in an order generated by a personal tracking system, generating a cone of visibility by pruning the user's personal navigation history according to a parametric model representing both an egocentric visibility constraint and an environment constraint, and determining a backtracking route based on the cone of visibility. Visualization data may be generated based on the backtracking route, resulting visualizations meant to guide a user back to an origin location.

The present application discloses a method of preparing a biological sample by low-temperature thermal evaporation, making the prepared sample highly suitable for subsequent MALDI-MSI analysis. The high vacuum pressure used in the method enables matrix evaporation at a low temperature, significantly reducing sample contamination and biological degradation during deposition, resulting in very pure matrix layers irrespective of matrix quality.

The present invention is a method to improve physical-sports performance, reduce fatigue, combat physical-sports aging, and to cure and prevent physical injuries, based on an effective dose of glycine, L-proline, L-lysine, L-aspartic acid (or L-aspartate, citric acid, or citrate), and vitamin C. The method is based on the limitations and subsequent conditions of the metabolism in three aspects: (1) the synthesis of ATP in mitochondria, dependent on the Krebs cycle; (2) the synthesis of proteins of the passive mechanical system (collagen and elastin); (3) the mechanism of muscle contraction in actin-myosin interaction cross-bridge cycles. while ensuring that the diet must contain a sufficient amount of protein.

Techniques for optical flow translation estimation by an inside-out location tracking system may include generating an updated distance parameter by optimizing a distance parameter using a translation vector and a set of other fixed terms of a homography for a set of matched image point pairs in an image, determining whether to keep or to discard the updated distance parameter, optimizing the translation vector using a current distance parameter, either the updated distance parameter or a prior distance parameter that was retained, thereby generating an updated translation vector. An optical flow translation method also may include evaluating for convergence, and iteratively optimizing the distance parameter and the translation vector until there is convergence. Once there is convergence, a current updated translation may be output. Convergence may depend on one or more predetermined thresholds relating to a size of parameter updates, an error reduction, and/or a number of iterations.

Techniques for map refinement (e.g., tracking data refinement) by an inside-out location tracking system may include computing a transform from a reference point to an epipolar line using an Essential Matrix derived from a reference frame camera motion in a live frame, computing several appearance errors between a feature associated with the reference point and other projected and optimized features, using a perpendicular projection hypothesis and an optimized point generated on the epipolar line, and evaluating the appearance errors using a greedy, ordered optimization. If the appearance error is less than a predetermined quality threshold, the optimized point is retained in tracking data. Otherwise the tracking data may be reset at the reference point location for reinitialization. An updated map and associated map data reflecting updated optimized points may be provided, for example, to a client device, as well as returned to a visual inertial odometry system.
