20160123860 | FUEL DENSITY DETERMINATION - A method for accurately determining a density of a fuel includes obtaining dielectric constant versus density characteristics of the fuel at a first location and measuring a dielectric constant of the fuel at a second location. The environmental conditions at the second location differ from environmental conditions at the first location. Density of the fuel at the second location is inferred using the dielectric constant of the fuel at the second location and the dielectric constant versus density characteristics of the fuel at the first location. | 05-05-2016 |

20100264325 | Ferroelectric Radiation Detector Employing Frequency Modulated Readout - A detector for electromagnetic radiation such as millimeter wave and infrared employs a ring-shaped ferroelectric element having a temperature affected by an absorber for the radiation. The dielectric constant of the ferroelectric material is a strong function of the temperature near its Curie temperature. The resonant frequency of the ferroelectric element is detected by applying a swept-frequency signal to the circuit and detecting the frequency which enhances the energy of the pulse. A two-dimensional camera for the radiation employs a two-dimensional array of these ferroelectric resonant circuits and a system for rapidly interrogating their resonant frequencies on a sequential basis. | 10-21-2010 |
