Abstract: A high-rotational speed cup-shaped grinding wheel includes an annular base, several blades and a flow splitting structure. The blades are fixed on a side of the base at an interval in a circumferential direction to form a blade ring. The side of the blade ring away from the base forms an annular working surface, and two adjacent blades are spaced apart from each other to form a water passage channel for delivering cooling water to the working surface. The flow splitting structure is fixed on the blade ring and splits the cooling water into two branches, where a first branch delivers the cooling water to an outer area of the working surface, and a second branch delivers the cooling water to an inner area of the working surface, and then delivers the cooling water from an inner area of the working surface to an outer side area thereof.

Abstract: A pyrogenicity test method and assay of endotoxins allows for rapid and ultrahigh sensitivity testing of parenteral pharmaceuticals or medical devices that contact blood or cerebrospinal fluid by employing a Limulus Amoebocyte Lysate (LAL) assay monitored with a photonic-crystal biosensor. The photonic-crystal biosensor is capable of determining the presence of endotoxins in a test sample by detecting shifts in the resonant condition of an open microcavity affected by the changes in the refractive index of the analyte solutions used.

Abstract: A cooling structure of a high-speed cup-shaped wheel includes a base and a blade ring. The blade ring is arranged on the base and is fixedly connected to the base. The blade ring is provided with a plurality of water channel groups, which is sequentially arranged at intervals in a circumferential direction of the blade ring. Each of the water channel groups includes two or more inner water channels, which are sequentially arranged at intervals in the circumferential direction of the blade ring, and the width of each of the two or more inner water channels in a radial direction of the blade ring is gradually increased. The cooling structure allows cooling water to cover the entire working surface to improve the cooling efficiency for the working surface and also to effectively improve the utilization efficiency of the cooling water.

The status information of the smart street parking meter includes an empty-space status of the street parking grid detected by the smart street parking meter and a battery status of a rechargeable battery of the smart street parking meter. The parking information of the vehicle includes the plate number of the vehicle, the parking fee of the vehicle, and a payment status of the parking fee of the vehicle.

Abstract: A tool-cooling mechanism includes a grinding tool. The grinding tool is provided with a converging disc, and the converging disc rotates with the grinding tool to draw external cooling water into the grinding tool for convergence, and then radially conveys the cooling water as converged toward an inner wall of the grinding tool, such that the cooling water can flow to a grinding surface along the inner wall of the grinding tool. The cooling water is allowed to enter via a water inlet and cool the grinding surface smoothly even when the grinding tool is rotating at a high speed, such that the cooling water can be prevented from passing through the grinding tool axially and failing to cool the grinding surface. In addition, the grinding surface is cooled after the cooling water as dispersed and atomized by the rotation of the grinding tool is converged.
