  • Process for no-detection in fluid media
    Patent number: 6231734
    Abstract: A process and apparatus for selective detection of NO in fluid media, particularly exhaust gases of internal-combustion engines. This process comprises the steps of positioning a nitrosonium-conducting solid electrolyte between two porous electrodes, acting upon one of the two electrodes with the NO-containing fluid medium, and measuring a voltage difference between the two electrodes as an indication of the NO-concentration in the NO-containing fluid medium.

  • Precision temperature transducer for measuring the surface temperature of the human and animal skin
    Patent number: 3938387
    Abstract: A transducer for measuring the surface temperature of the human and of animal skin with a resolution of 0,02 K (0.04.degree.F), a calibration accuracy to within 0,1 K (0,2.degree.F) absolute and a response time within 2 ms has been developed. The transducer includes a tube transparent to thermal radiation and open at both ends. A temperature sensing element is suspended across one end for placement adjacent to the skin.
