  • Publication number: 20190137552
    Abstract: A method for determining a dynamic rating for a conductive path includes using a sensor to measure a value for a load parameter and selecting a heating process associated with the load parameter. A rated temperature change is changed by removing temperature changes due to a heating process other than the selected heating process to produce an impaired rated temperature change. A thermal load percentage is determined from the impaired rated temperature change. The thermal load percentage and the measured value are then used to determine the dynamic rating for the load parameter. A method also includes measuring a temperature rise, a current, and a voltage on the conductive path multiple times. Using at least two basis functions and the multiple measured temperature rises, currents and voltages, the values for at least two variables are determined. Trends in each variable are determined to determine a condition of electric equipment.

  • Patent number: 9419334
    Abstract: A measurement device for operating in high voltage electrical fields such in high voltage electrical switchgear, having a sensor and a ?/2 monopole helical antenna coupled thereto. The antenna is coupled to a ground via return stub in lieu of the common ground plane. The antenna is made of wire having a sufficiently large diameter to prevent forming corona discharge point electrode throughout the outer surface of the volume defined by the antenna, thus minimizing corona discharge risk. The antenna further provide relative immunity from induced voltage at the 50-400 Hz range from the high voltage fields, allowing ESD sensitive devices to operate in close proximity to the high voltage conductors.

  • Publication number: 20150228813
    Abstract: A CRTR (Continuous Resonant Trap Refractor) is the name given to waveguides having a tapered core and a cladding which disperses radiant energy admitted via the aperture at the wide end of the tapered core, and emits the energy in sorted fashion via the cladding. As individual waves reach a width of the core in which they can not propagate along the tapered core waveguide, and are emitted via the cladding sorted at frequency dependent depth. Alternatively, the CRTR admits radiant energy via the cladding and mixes and emits the combined energy via the aperture. The present invention is directed The invention discloses several uses of CRTRs and aspects of the invention include inter alia imagers, camouflage devices, radar and heat signature reduction devices, communications, target designation, and the like.

  • Patent number: 8073640
    Abstract: The current invention relates to a conductivity-dielectric (CD) electrode design with apertures that allow compressional waves to propagate away from the surface of the acoustic wave device unimpeded. This prevents reflection of compressional waves that would interact with the viscosity sensor surface, thus altering the device response. It allows compressional waves to pass through, and allows the dual mode viscosity sensor responses to be utilized for density/viscosity/elasticity measurement and correlation. The invention further offers methods of instrumentation to detect unwanted reflections, to compensate, and to correct for the distortions caused by reflections. Finally, the invention provides a system and method for utilizing deliberately introduced reflections to obtain additional information, including fluid density.

  • Patent number: 8022595
    Abstract: A composite acoustic wave device provides improved protection from environmental factors while maintaining high electrical characteristics and dynamic range is provided. The device comprises a rigid protector plate having high quality acoustical characteristics and a thickness which is a multiple of half wavelength of the resonant frequency. A piezoelectric plate is coupled to the protector plate, is supported therefrom, and forms an energy interface therewith. The piezoelectric and protector plates are dimensioned such that a wave of resonant frequency traveling between the excitation face and the loaded/sensing face, forms a substantially continuous-phase wave, at substantially peak amplitude, at the energy interface. By doing so the device decouples the electrical thickness of the wave device from the mechanical thickness thereof.
