Abstract: A method of analyzing swing of a player of a sport is disclosed. A system uses sensors to capture data representing a path of motion of a sporting good (such as a bat) object as a person swings the object toward a target (such as a ball), over multiple swings of the object. For each of the captured paths of motion, the system determines a slot representing a portion of the swing along which the object traveled in approximately a straight line leading to a point of impact with the target. The system saves the slots to a swing fingerprint data set in a data store. The system generates a visual representation of the swing fingerprint data set by outputting the slots on a display as viewed one or more viewing angles and/or dimensions.

Abstract: A method for stepwise extraction of silica and hydroxide from silicate substances. The silicate substances are leached by chlorine-containing inorganic acids, and the hydroxides are extracted step by step from the leaching liquor by electrochemical deposition method; The raw material of the powder is put in the reactor, inorganic acids, water-soluble alcohol and water are added as the leaching liquor, heated and reacted under the condition of 0.1 MPa or more, and the acidic multi-ion mixed solution and filter residue are obtained by filtration. The acidic multi-ion mixed solution is heated and boiled, and the silicon-containing volatile components are collected, decomposed and deposited in the collector; The deposited volatile components is dried to obtain high purity silica powder; The filter residue is washed and dried to obtain silica; The hydroxides are extracted from the acidic multi-ion mixed solution by electrochemical deposition method.

Abstract: A microneedle chip and manufacturing method. The method comprises injecting, into a female mold, a fluid needle liquid, wherein forming cavities matching the shapes of needles of a microneedle chip are provided at the female mold and form a cavity array, injection inlets are provided at a surface of one side of the female mold, and air ejection openings are provided at a surface of another side of the female mold to form an air ejection surface; covering the air ejection surface of the female mold using a breathable film, and during injection, passing a gas through the breathable film so as to retain the liquid inside the forming cavities; curing the fluid needle liquid to form the microneedle chip, and demolding to obtain the same. By employing the air ejection openings and the breathable film, a liquid is retained while ejecting a gas, providing a favorable micro-injection effect.

Abstract: A player calibrates the initial position and orientation of trajectory using their natural sports motion from a well-defined starting point. For example, a batter with mature swing mechanics maintains approximately the same bat orientation and position (“load configuration”) at the beginning of their swing. This load configuration is unique to that player and unlike that of other players and may represent the start of a swing (or other motion of interest) or may occur at any characteristic point in time during the motion. Subsequent motion data within the spatial frame can be accurately analyzed so that three-dimensional trajectory of the equipment or body segment can be precisely determined and presented in an animated playing environment on devices such as smartphones, tablets and laptops.

Abstract: A system and method for calibrating an inertial motion sensor attached to an article of sports equipment or to a body segment in accordance with the user's initial orientation and location at the beginning of a sports motion. The sensor captures real-time motion data and the calibrated initial orientation and location provide absolute heading angle and starting position of the equipment or body segment in a spatial frame. Subsequent motion data within the spatial frame can be accurately analyzed so that three dimensional trajectory of the equipment or body segment can be precisely determined and presented in an animated playing environment on devices such as smartphones, tablets and laptops.
