  • Patent number: 6107630
    Abstract: A radiation detector includes a plurality of detector elements arranged on a detector substrate in an interdigitated linear array. A thermoelectric or other cooler is attached to the lower surface of the detector substrate. A pair of interconnect boards is positioned on opposite sides of the detector substrate. The detector elements, substrate, cooler and pair of boards are received in a sealed housing and a radiation transmitting window in the housing permits radiation to pass into the housing and strike the detector elements. A plurality of conductive pins extends through the housing and terminates at electrical traces on the interconnect boards. A thermistor or other temperature sensor is attached to the detector substrate and, through control of the thermoelectric cooler, maintains the detector substrate at a desired operating temperature.

  • Patent number: 6088605
    Abstract: A method and apparatus (12) for the non-invasive sensing of blood glucose levels includes apparatus (10) which moves the forearm of the patient in a controlled incremental manner to take a plurality of spectral skin measurements and averaging the measurements for the purpose of accounting for biological differences that exist in the patient's skin.

  • Patent number: 4594024
    Abstract: An offshore intake structure for a water cooling system having an intake shaft communicating with a lake or like reservoir comprises a well excavated in the bed of the lake having an opening communicating with the intake shaft. The well is covered by a submarine roof structure having a perforate outer region defining an inlet to the well and an imperforate inner region which extends over the intake shaft opening and radially outwards therefrom so as to define with the well bottom a horizontal flow passage extending inwards to the intake shaft. The construction is such as to permit an adequate intake flow while keeping the intake velocity below the limit at which fish would be entrained.

  • Patent number: 4147051
    Abstract: A densimeter for measuring the density of liquids is disclosed. The densimeter comprises a substantially vertical shaft having a central axis. The densimeter further comprises means for rotating the shaft about its axis and a vessel mounted on the shaft asymmetrically with respect to the shaft axis. Counterbalancing means are provided on the shaft for at least partly compensating for the asymmetry. The shaft is resiliently mounted with freedom of oscillation transverse to the shaft axis. Means are provided for measuring the amplitude of the oscillations.
