Abstract:
The present invention discloses a counterweighted vibration device and a manufacturing method thereof. The counterweighted vibration device includes a shell provided with a hollow cavity and a vibration assembly, wherein the shell is provided with two elastic support structures located at two ends of the vibration assembly, and the shell is further provided with slots configured for passage of the two ends of the vibration assembly and to be in communication with the hollow cavity; the vibration assembly includes two counterweights each located at one of the two ends thereof, short strong magnetic strips each adjacent to one of the counterweights, a long strong magnetic strip located between the two short strong magnetic strips, and two fixing screws located on two sides separately and configured to couple the counterweights, the short strong magnetic strips and the long strong magnetic strip together; the vibration device further includes two coils, and a change in a current flowing through each of the two coils causes a magnetic force to change, so as to produce vibration of the vibration assembly in proportion to the change in the current; and the counterweights are of a non-magnetic material. In the present invention, a magnetic field generated by the short strong magnetic strips and the long strong magnetic strip is limited to a smaller range, so that the movement range of the magnetic field of the vibration assembly during vibration is reduced, thereby reducing the influence on the coils and providing a better vibration effect.

A rapid thermal processing system includes a rapid thermal processing furnace, a back electrode substrate, and a cover. The rapid thermal processing furnace includes a reaction chamber and a heating device. The heating device is capable of generating heat energy. The back electrode substrate is adapted to dispose in the reaction chamber and has a precursor layer and a selenium layer formed on the precursor layer.

Abstract:
A static image compression method, a computer readable data structure, and a computer readable storage medium are described. Firstly, an image is segmented into a plurality of sub-images. Then, each sub-image is sequentially compressed into a sub-data frame having a start character, so as to generate a compressed data with the sub-data frames interconnected according to a sequence of the sub-images. Finally, the addresses of the start characters are recorded to generate an index data. Thereby, the start character of a particular block can be obtained from the index data, and the sub-image of the particular block is preferentially decoded and displayed.

A symbol recognition method for increasing the symbol recognition speed by the processor includes the steps of obtaining a pixel density value and an aspect ratio of the symbol image. Then, the center-point value and the corresponding radius value are obtained by a partitional clustering algorithm. In sequence, a pixel density value and the aspect ratio of the under recognized image are obtained, and compared with the values of the symbol image to determine whether the under recognized image is a single symbol image or not.
Abstract:
An illuminating wrist exerciser includes upper and lower casing members, a ring, a rotor, a magnetic element, an illumination control circuit board, a plurality of illuminators, and a coil holder. The upper and lower casing members mate each other to form an interior space receiving the rotor therein. The upper casing member forms in a top portion thereof an opening to partially expose the rotor. Opposite ends of the rotor are rotatably coupled to the ring surrounding the rotor. The magnetic element is mounted to the ring. The illumination control circuit board and the coil holder are received in a recess defined in one of the ends of the rotor. The coil holder forms a bore in which the magnetic element is received. The coil holder carries thereon at least one pair of coils. The illuminators are distributively arranged on an outer surface of the rotor and are electrically connected to the illumination control circuit board. Electrical power is induced by the magnetic interaction between the coils of the coil holder and the magnetic element and is fed to the illumination control circuit board, which in turn controls the lighting/darkening of the illuminators to thereby provide a power-generation, illuminating wrist exerciser.
