  • Patent number: 6005531
    Abstract: An antenna assembly for an active electronically scanned array includes, among other things: an array of antenna elements; an RF signal feed and circulator assembly coupled to said antenna elements and forming thereby an array of radiating structures; a generally planar RF manifold assembly having regularly spaced openings therein located behind and normal to the radiating structures; an array of T/R modules connected to the array of radiating structures and having respective RF connector assemblies forming a portion of an RF interface at one end portion of each of the modules which project upwardly through said spaced openings in the RF manifold and wherein the respective connector assemblies thereof connect to at least one immediately adjacent circulator as well as to transmit and receive manifold portions of the RF manifold; each of the T/R modules further have a heat sink plate on the back side thereof which is positioned against one of a number of elongated liquid coolant circulating coldplates connected

  • Patent number: 5500187
    Abstract: An assay device for detecting the presence of analytes in an unknown sample including a reaction system wherein storage reservoirs containing reagent are fluidly connected to a track containing the sample. An actuation mechanism forces the reagent from the reservoirs and into the track where it mixes the reagents together and then with the sample at a first flow rate. The mechanism then reduces the force on the reagent to allow a second flow rate less then the first flow rate to force the reagent and sample mixture through the track so that reaction can occur, whereby a determination as to whether the target analyte was present may be made.
