  • Variable flexure-based fluid filter
    Patent number: 7188731
    Abstract: An apparatus and method for filtering particles from a fluid comprises a fluid inlet, a fluid outlet, a variable size passage between the fluid inlet and the fluid outlet, and means for adjusting the size of the variable size passage for filtering the particles from the fluid. An inlet fluid flow stream is introduced to a fixture with a variable size passage. The size of the variable size passage is set so that the fluid passes through the variable size passage but the particles do not pass through the variable size passage.
    Type: Grant
    Filed: August 25, 2003
    Date of Patent: March 13, 2007

  • Automated nucleic acid assay system
    Publication number: 20030032172
    Abstract: A nucleic acid assay system includes a holding means that receives a sample and a reagent. A PCR reactor means amplifies the sample and produces an amplified sample. A detection means detects PCR amplicon. A transport means selectively transports the sample and the reagent relative to the holding means, the PCR reactor means, and the detection means. A control means is provided for selectively adding the reagent to the sample, mixing the sample and the reagent, performing PCR amplification, and detecting PCR amplicon. A decontamination means is provided for decontaminating the holding means, the PCR reactor means, and the detection means.
