  • Publication number: 20200197679
    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.

  • Publication number: 20190335563
    Abstract: The present disclosure provides a protection circuit, a drive system, a chip and a circuit protection method, and a drive method. The protection circuit can be used in a circuit system in which a load is driven by a switch circuit, and acquire a voltage signal reflecting the voltage of a power supply bus on which the load located and generate a detection signal, and control the switch circuit to maintain a forcible non-conductive state within a protection period when detecting that the voltage of the detection signal satisfies a preset voltage warning condition. The present application solves the problem of circuit protection of DC-powered electronics in the prior art.

  • Publication number: 20180154211
    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.
