  • Publication number: 20190312933
    Abstract: This application is directed to a distributed data processing method performed at a server system coupled to a linear communication orbit. The server system has a plurality of function modules. Each function module is configured to collect data related to a core function from the linear communication orbit. Each function module includes an internal client configured to adaptively perform a set of data processing operations according to a schema definition, including generating a data collection request for collecting raw data items, sending the data collection request through the linear communication orbit, collecting the requested raw data items from a set of machines via the linear communication orbit, and performing analysis on the collected raw data items. In some embodiments, a central data management module of the one or more servers is configured to provide the schema definition to and receive result data reported from the function modules.

  • Publication number: 20090209030
    Abstract: A thermalcycler is constructing with a first thermalcycler body section of a flexible circuit material or a circuit board material. The first thermalcycler body section has a first face. A first cavity portion is formed in the first face. A second thermalcycler body section is constructed of a flexible circuit material or a circuit board material. The second thermalcycler body section has a second face. A second cavity portion is formed in the second face. When the first cavity portion and the second cavity portion are positioned together they form a cavity. A thermalcycler unit is positioned in the cavity. The first thermalcycler body section and the second thermalcycler body section are connected together with the first face and the face opposed to each other and the thermalcycler unit operatively connected to the first cavity portion and the second cavity portion.

  • Patent number: 6893863
    Abstract: A sleeve-type silicon polymerase chain reaction (PCR) chamber or thermocycler having improved thermal performance. The silicon sleeve reaction chamber is improved in thermal performance by etched features therein that reduce thermal mass and increase the surface area of the sleeve for cooling. This improved thermal performance of the thermocycler enables an increase in speed and efficiency of the reaction chamber. The improvement is accomplished by providing grooves in the faces of the sleeve and a series of grooves on the interior surfaces that connect with grooves on the faces of the sleeve. The grooves can be anisotropically etched in the silicon sleeve simultaneously with formation of the chamber.

  • Publication number: 20040072334
    Abstract: A thermalcycler for processing a sample holder includes a first thermalcycler body with a first face and a second thermalcycler body with a second face. A cavity for receiving the sample holder is formed in at least one of the first face or the second face. A thermalcycling unit is operatively connected to the cavity.

  • Patent number: 6586233
    Abstract: A polymerase chain reaction system provides an upper temperature zone and a lower temperature zone in a fluid sample. Channels set up convection cells in the fluid sample and move the fluid sample repeatedly through the upper and lower temperature zone creating thermal cycling.

  • Patent number: 5859887
    Abstract: A nuclear fuel assembly support grid formed from a lattice structure having an egg-crate design with the interior lattice straps joined to a perimeter strap generally at least three locations along its length; with at least two of those locations being affixed by shear joints. The shear joints are formed from weld tabs extending from the ends of the interior lattice straps, at appropriate locations, which fit into corresponding slots in the perimeter strap. The weld tabs are then brazed or welded, as appropriate to the base metals being joined, after being inserted. The weld segments can be designed with twist tabs at their end, that can be deformed after being inserted into the corresponding slots in the peripheral strap, to hold the fixture in place while it is being bonded. In another embodiment, the interior lattice straps are joined to the perimeter strap by two shear joints formed respectively at the very top and bottom of the interface.
