  • Publication number: 20230084486
    Abstract: The subject disclosure relates to a system and method for testing units-under-test (UUT) with a thermal shock. The thermal shock testing system can include a chamber having an inlet and an outlet, the chamber being configured to provide a thermal shock to a unit-under-test (UUT), a pump configured to fluidly connect to the inlet of the chamber and direct a temperature controlled liquid through a channel embedded in the chamber, and a boiler and a chiller fluidly connected to the pump, the temperature of the liquid being controlled by at least one valve configured to alternatively direct hot or cold fluid to the inlet of the chamber.

  • Publication number: 20050001721
    Abstract: The present invention describes a wireless system and method for distributing sensors in large numbers that makes possible the application of a number of algorithms for the extraction of important physical quantities. More specifically, the method involves (a) formation of an electromagnetic waveguide by the application of a polymer, or other dielectric material, on the exterior of the hull of a vessel; (b) insertion of sensors/radio units within the waveguide, the sensors being arranged to sample the fields of interest; and (c) insertion of radio transceiver base stations in the waveguide to communicate and extract data from the sensor/radio units. The wireless system of the present invention is implemented with a very high sensor count whose outputs are processed to recover exterior field quantities without the requirement of direct measurements off of the vessel's structure.

  • Patent number: 6395842
    Abstract: A polymer support is provided which comprises hydroxypolyC2-4 alkyleneoxy chains attached to a cross-linked polymer. The hydroxypolyC2-4 alkyleneoxy chain contains from 2 to 8 C2-4 alkyleneoxy groups and the polymer support has from about 0.1 to about 5 meq free hydroxy groups per gram of polymer. Preferably, the cross linked polymer is a copolymer comprising phenylethylene and 4-hydroxyphenylethylene units or phenylethylene and 4-chloromethylphenylethylene units.
