  • Publication number: 20120314204
    Abstract: A cell/particle analyzing device includes a light-emitting unit, a light-diverting unit, a first receiving unit and a second receiving unit. The light-emitting unit generates a first light beam. The light-diverting unit is connected to the light-emitting unit and has an input end, a bidirectional transceiving end and an output end. The input end receives the first light beam generated by the light-emitting unit. The bidirectional transceiving end transmits the first light beam generated by the light-emitting unit and receives a second light beam. The output end outputs the second light beam. The first receiving unit is connected to the output end of the light-diverting unit and receives the second light beam. The second receiving unit is aligned with the bidirectional transceiving end.

  • Publication number: 20120174616
    Abstract: A generator includes a liquid tank, a high temperature device and a nozzle unit. The liquid tank has a receiving room. The high temperature device is disposed on a surface of the liquid tank. The nozzle unit includes a tank, an injecting tube, a nozzle and an oscillating device. The tank is disposed in the receiving room and filled with a working fluid. The injecting tube has one end communicating with the tank. The nozzle is disposed on a surface of the tank and faces the high temperature device. The oscillating device is disposed on the tank to induce oscillation of the working fluid in the tank, wherein the oscillation changes the pressure of the working fluid so that the working fluid is pulled towards the nozzle and is sprayed on the high temperature device by the nozzle.

  • Publication number: 20110097200
    Abstract: A wind power turbine includes a frame, a drag-type fan unit and a lift-type fan unit. The frame has a base, a shaft, an electricity generator and a plurality of air-guiding vans. The air-guiding vans are disposed on the base, and the shaft has one end connected to the electricity generator. The drag-type fan unit has a plurality of drag-type blades coupled to an outer circumference of the shaft. The lift-type fan unit has a plurality of lift-type blades disposed around the drag-type blades. Each of the air-guiding vans has a first side and a second side, and the first and second sides are parallel to the shaft. An air inlet is formed between the first sides of adjacent two of the air-guiding vans, and an air outlet is formed between the second sides of adjacent two of the air-guiding vans. The air inlet is larger than the air outlet.

  • Publication number: 20100325364
    Abstract: A cache controller, a method for controlling the cache controller, and a computing system comprising the same are provided. The computer system comprises a processor and a cache controller. The cache controller is electrically connected to the processor and comprises a first port, a second port, and at least one cache. The first port is configured to receive an address of a content, wherein a type of the content is one of instruction and data. The second port is configured to receive an information bit corresponding to the content, wherein the information bit indicates the type of the content. The at least one cache comprises at least one cache lines. Each of the cache lines comprises a content field and corresponding to an information field. The content and the information bit is stored in the content field of one of the cache lines and the corresponding information field respectively according to the information bit and the address. Thereby, instruction and data are separated in a unified cache.

  • Publication number: 20080259206
    Abstract: An adaptive de-interlacer can convert an interlaced video signal into a progressive video signal, and comprises an intra-field interpolator, an inter-field interpolator, a static pixel detector, a motion detector and a blending unit. The intra-field interpolator outputs an intra-field interpolated pixel based on a current field of the interlaced video signal, and the inter-field interpolator outputs an inter-field interpolated pixel based on successive fields of the interlaced video signal. The static pixel detector detects whether each interpolated pixel is a static pixel based on luminance differences between pixels of the successive fields with reference to a threshold and outputs a detection result. The motion detector generates a motion value for the interpolated pixel based on the successive fields and the detection result.
