  • Patent number: 5525475
    Abstract: The diffusion through a membrane assaying apparatus and method facilitates rapid detection of small or larger molecular weight substances such as hazardous wastes, toxic chemicals or the like by using a semipermeable membrane having a predetermined molecular weight cutoff. The semipermeable membrane is provided as part of a container having a removable barrier which facilitates control of diffusion through the membrane. The assaying method includes the use of a reaction mechanism for detection of a predetermined substance. The reaction mechanism includes one or more reagents which are designed to either react or compete for a substance for which assaying is being performed. By selecting the proper reagents and molecular weight cutoff of the semipermeable membrane, the presence or absence of a reaction such as a color change or production of vapor provides indication whether the substance being assayed for is present in the test sample.

  • Patent number: 5364795
    Abstract: An apparatus and method for the sensitive detection of atmospheric and/or surface absorbed nitrocompounds has been developed. The apparatus and method may be employed to detect the presence or absence of propellants, explosives, and nitropollutants. The unique feature herein is that the apparatus and method employ one laser operating at or near 226 nm. The laser photofragments the target molecule and facilitates the detection of the characteristic NO fragment, by resonance-enhanced multiphoton ionization (REMPI) and/or laser-induced-fluorescence (LIF) via its A.sup.2 .SIGMA..sup.+ -X.sup.2 II.sub.i transitions. The analytical utility of this apparatus and method has been demonstrated on numerous compounds, such as, DMNA, nitromethane, nitro-benzene, TNT, and RDX. With the present system, a limit of detection of 8 and 24 ppb is obtained for RDX and TNT, respectively, using only 100 micro-Joules per pulse of laser energy.

  • Patent number: 5325388
    Abstract: GaAs base optical waveguide-based structure for a neural network is discld which may form the basic functional building block of a neural architecture in which the waveguide architecture contains at least three electrically active components which are electrically isolated from each other. The waveguide parameters are such that the laser light propagating through the waveguide is a single-mode in both transverse and lateral directions. A superlattice structure is incorporated in the waveguide core and results in electroabsorption of the input laser light. An electric field is supplied to the active components in order to change the transmission properties of the core material, thus modulating the light passing through the core material.

  • Patent number: 5315681
    Abstract: A detector card strain relief system for use with a fiber optic detector system is disclosed in which a detector card/strain relief brace is permanently fixed to the detector card for receiving a plurality of optical fibers exiting from a like plurality of detector cans. The plurality of optical fibers pass through two strain reliefs which are connected to either end of a monocoil. Each of the strain reliefs is connected respectively to the detector card/strain relief brace and a fiber termination mount such that the termination mount cannot be moved without moving the detector cans and, thus, the optical fibers are protected from pulling away from the detector cans while at the same time allowing for proper cooling of the detector cans and minimizing light leaking from the optical fibers. Alternate embodiments for the detector strain relief brace are provided such that the optical fibers may exit from the bottom or the side of the detector card.
