  • Passive sensor for measuring ionizing radiation
    Patent number: 11156729
    Abstract: The present invention is a passive sensor to detect ionizing radiation over time. It employs a SAW sensor that incorporates a polymer film that deforms based on the chain-scission reaction as described upon irradiation. The polymer film coats the piezoelectric substrate and reflectors on the SAW sensor and, as it reacts to radiation, the film deforms due to the fracturing of the polymer molecules resulting in a loss of overall mass. As the SAW sensor is interrogated by an electrical signal, the wavelength of the response will change as the overall rigidity of the polymer film changes allowing for the detection of the level of radiation.

  • Incorporation of chemochromic pigment into a variety of articles as an indicator for the presence of hypergolic fuels
    Patent number: 8815603
    Abstract: A chemochromic indicator is provided that includes a hypergolic fuel sensing chemochromic pigment that change from a first color to a second color in the presence of a hypergolic fuel. In a first embodiment, a chemochromic indicator is provided for detecting the presence of a hypergolic fuel such that the irreversible hypergolic fuel sensing chemochromic pigment includes potassium tetrachloroaurate (KAuCl4). There are several types of chemochromic indicators, for example, the article used to form the chemochromic indicators include, but are not limited to, wipe materials, silicone/TEFLON tape, manufactured parts, fabrics, extruded parts, and paints.
