  • Publication number: 20240139738
    Abstract: According to the disclosure, a target analyte detection cartridge includes a sample chamber into which sample is inserted, a metering chamber connected to the sample chamber to meter a predetermined amount of sample, a mixing chamber connected to the metering chamber to receive a magnet bead, and a waste chamber connected to the metering chamber. The metering chamber has one side connected to each of the sample chamber and the mixing chamber and another side connected to the waste chamber. A first pneumatic flow path to which pneumatic pressure is provided is connected to a waste flow path that joins the other side of the metering chamber to connect the metering chamber and the waster chamber.
    Type: Application

  • Patent number: 6945781
    Abstract: An integrated evaluation and simulation system for advanced naval gun systems interactively evaluates concept design decisions and design requirements in the context of a virtual representation of an operational advanced naval gun system. The combat effectiveness of an advanced naval gun system may also be concurrently tested by virtual simulation. A computer system is programmed to implement a causal network model comprising an integrated collection of analysis models for creating a virtual representation of an advanced naval gun system. The integrated evaluation and simulation system also includes a user interface operatively connected to at least the computer system, for selectively inputting data into the causal network model and receiving information therefrom, and preferably at least one virtual simulation system.
