  • Publication number: 20130084737
    Abstract: An electrical connector includes an electrical connecting base, a press cover, a fastening member and at least one thrust member. The press cover covers on the electrical connecting base, and substantially horizontally placed. A fastening portion and a pivoting portion are respectively formed on two opposite ends of the press cover. The press cover is opened or closed relative to the electrical connecting base around the pivoting portion. The fastening member correspondingly presses against the fastening portion of the press cover when the press cover is horizontally placed. The at least one thrust member urges against the press cover upwards. When the fastening member is released from pressing against the fastening portion, the press cover is urged to pop up, so that an operating space is formed below the press cover, which is sufficient for an operator to open the press cover manually.

  • Publication number: 20130005591
    Abstract: A new method that enables parallel amplification of nucleic sequences from a complex source is disclosed. The amplification is compartmentized into microdroplets by porous-walled hollow glass microspheres and subjected to PCR thermal cycling or isothermal amplification. The rigid wall of the glass microspheres allows very simple and conventional manipulation of the amplification products for downstream application such as sequencing or detection of copy number of specific sequences in a complex sample.

  • Publication number: 20110006820
    Abstract: A dual phase-locked loop (PLL) circuit includes a phase/frequency detector, a charge pump, a frequency tuning circuit and an N divider. The frequency tuning circuit includes a coarse-tuning circuit, for coarse-tuning an output frequency of the dual PLL circuit to approximate a target frequency; a fine-tuning circuit, for fine-tuning the output frequency of the dual PLL circuit to the target frequency; and a current control oscillator (CCO), for generating an output signal of the dual PLL circuit. The output frequency of the output signal is equal to the target frequency.

  • Patent number: 6975943
    Abstract: A simplified strategy for sequencing large genomes has been developed. Clone-Array Pooled Shotgun Sequencing (CAPSS) is based upon pooling rows and columns of arrayed genomic clones, for shotgun library construction. Random sequences are accumulated and the data are assembled by sequential comparison of rows and columns, to resolve the sequence of clones at points of intersection. Compared to either a clone-by-clone approach or whole genome shotgun sequencing, CAPSS requires relatively few library constructions and only minimal computational power for a complete genome assembly. The strategy is suitable for sequencing large genomes for which there are no sequence-ready maps, but for which relatively high resolution STS maps and highly redundant BAC libraries are available. It is immediately applicable to the sequencing of mouse, rat, zebra fish and other important genomes, and can be managed in a cooperative fashion to take advantage of the distributed international DNA sequencing capacity.
