  • Patent number: 7582913
    Abstract: A lens and an LED using the lens to achieve homogeneous illumination include a region. The region around the optical axis of a lens is designed to be concave and form a divergent surface. The upper surface of the lens is a continuous curved surface to diverge the high-intensity light emitted by the LED in the vicinity of the optical axis through refractions. Therefore, the LED can homogeneously illuminate a larger area.

  • Patent number: 7582483
    Abstract: A method of detecting and quantifying viable cells in a sample. The method includes fluorescently staining the cells by adding a fluorescent dye into the sample or putting the sample in contact with the fluorescent dye. A quenching dye is then added to the stained sample, or the sample is put into contact with the quenching dye, at a pH different from the pH in the viable cells. The quenching dye used is permeable through the membrane of a viable cell and does not readily absorb fluorescence of the fluorescent dye at the pH in the viable cells, but absorbs the fluorescence of the fluorescent dye at the pH of the fluorescent dye. Next, the sample, now stained with the fluorescent dye and the quenching dye, is illuminated by an excitation light for the fluorescent dye at a pH different from the pH in the viable cells and the fluorescence emitted from the sample is collected and detected.

  • Patent number: 7581143
    Abstract: A peripheral component interconnect (PCI) bus test system and method therefor, that is applied in a PCI test card. The PCI test card includes a static random-access-memory (SRAM). In the method, the data transaction of the PCI bus signal is disintegrated into a separate data operation, while eliminating the waveform interfering transaction. Through comparing the waveform of the data operation as separated from a PCI bus signal with the standard PCI bus waveform, the quality of the PCI bus signals can be precisely analyzed, thus realizing the hardware test of PCI bus.

  • Patent number: 7579990
    Abstract: A first estimated location of a target terminal to be estimated in its location is obtained based on information derived from radio signals for location estimation and also locations of anchor terminals. Then, on the basis of the first estimated location thus obtained, estimated distances are calculated while expected values are calculated based on information required for location estimation to compare the estimated distances with the expected-values. Depending on the comparison result, one or more anchor terminals are selected as nonuse terminals. On the basis of information required for location estimation derived from radio signals sent by the anchor terminals other than the selected nonuse terminals and also on the locations of the anchor terminals except the nonuse terminals, a second estimated location of the target terminal is obtained.

  • Patent number: 7577162
    Abstract: Methods for allocating transmission bandwidths of a network are provided. The allocation ratio of anticipation bandwidths is adjusted according to the loading of the network to calculate the requested bandwidths, thereby effectively reducing an average delay and enhancing the utility rate of the network. Further, remaining bandwidth of the network is allocated based on maximum used bandwidth and bandwidth compensation of each terminal during the transmission cycle, to allocate excess bandwidth for each terminal. Therefore, the transmission bandwidth allocation is fairer, and delay is reduced. Upstream order of each terminal is transferred based on its requested bandwidth, thereby effectively reducing the average delay.
