Abstract: A device for measuring the fugacity of a material, without requiring a separate device to measure temperature, is disclosed, wherein the device is a solid electrolyte probe, with the probe having a passageway therein, and metallic conductor leads on the outside of the probe and on the inside of the probe in the passageway. The metallic conductor leads are in contact with an E.M.F. measuring circuit, with the reference fluid being passed through the passageway. The passageway also includes a capillary restriction therein, and measuring devices are provided to measure the pressure drop of the reference fluid when flowing through the capillary, thereby permitting determination of temperature. The temperature determination combined with the E.M.F. measurement permit determination of the fugacity of the material.

Abstract: A frequency modulated continuous wave radar signal is transmitted to a tat and the signal reflected from the target is compared with a sample of the continuous wave transmitter to produce a difference frequency signal. The difference frequency signal is band-pass amplified, wide-band limited, and processed by two frequency discriminators displaced from each other in the frequency domain, but both within the frequency band of the limiter and band pass amplifier. Detectors, integrators, and thresholding circuits determine, with suitable false alarm rates, in which half of which discriminator the difference frequency signal is concentrated.
