PREVENTION OF BIOFILM IN HEMODIALYSIS WATER SYSTEMS

Not Available HYPRES proposes to develop a novel passive, millimeter-wave imager (PMWI) of much lower cost than competing types. The PN1WI will employ a staring array of micromachined detectors, each coupled to its own thin-film antenna and feedhorn. Until the present, the sensitivity of such a scheme has not beau adequate for passive imaging. Recent advances in micromachined arrays for the infrared, however, can also be adapted to millimeter-wave imaging, raising the sensitivity to the necessary levels. The resulting P5IWI system will feature complete integration on a single chip of detectors, antennas, feedhorns and CMOS readout circuitry. The advantages of this approach include high reliability, low fabrication COST, small system size, and the elimination of scanning by the use of a full two-dimensional staring geometry. In Phase I HYPRES will design and fabricate a full two-dimensional array with off-chip read-out of a single line of detectors. In Phase 0, an integrated on-chip CMOS read-out of the entire array will be developed. BENEFITS: The passive millimeter-wave imager will find application in airport security systems, imagers for locating forest fires through dense smoke, and navigation aids for planes and boats in foggy environments. The low cost and small size of the imager will make it attractive for a wide range of military and commercial customers.
