  • DRIVEN STARTER PUMP AND START SEQUENCE
    Publication number: 20120131919
    Abstract: Various thermodynamic power-generating cycles are disclosed. A turbopump arranged in the cycles is started and ramped-up using a starter pump arranged in parallel with the main pump of the turbopump. Once the turbopump is able to self-sustain, a series of valves may be manipulated to deactivate the starter pump and direct additional working fluid to a power turbine for generating electrical power.

  • System and method for source identification for a chemical release
    Patent number: 8190376
    Abstract: A system for predicting a source location and release rate of a hazardous substance uses the basic knowledge of meteorological information (wind speed, direction, and stability) and two or more concentration measurements of the chemical released. Horizontal dispersion information obtained from surface meteorological data at sensor locations are used to narrow the search domain for the release location, reducing the computational cost. Each of the possible release locations in the search domain and possible release rates are evaluated in a process that predicts a concentration measurement at a sensor, based on a predicted location and release rate. The location and release rate that results in a least error when compared to an actual concentration measurement at the sensor are chosen as the source of the chemical and the release rate from the source.

  • Single aperture multiple optical waveguide transceiver
    Patent number: 8190030
    Abstract: A single-aperture, multi-axial transceiver is provided that is particularly useful in a LIDAR system for detecting low velocities at increased ranges. The system is particularly useful in systems that are required to measure very low velocities and very short distances as well as to provide an operating range of hundreds of meters. The transceiver uses closely spaced waveguides placed near the focal point of a single objective 8 to form input and detector apertures. Preferably the input and detector apertures are spaced from each other by less than about 80 ?m. In an embodiment using light with a wavelength of 1550 nm, the spacing is preferably about 30 ?m.

  • System and method for measurement of distance to a tag by a modulated backscatter RFID reader
    Patent number: 8188908
    Abstract: Distance to a modulated backscatter tag is measured with a RFID reader that measures changes in phase with frequency of modulated backscattered RF signals. Measured distances are linked to a specific tag. The effects of other sources of reflected and interfering signals are mitigated. The techniques eliminate the need for high RF bandwidth used in time-of-flight methods, and may be used with linear, limiting or other types of amplifiers in the reader receiver. Unambiguous distance to a tag may be found using the derivative of phase with RF frequency of the modulated signal backscattered by a tag. The distance to a tag can be measured with an accuracy on the order of a centimeter. The techniques utilize the characteristics of cooperative backscatter tags (transponders, labels, etc.). New readers implement the techniques which may use unmodified tags.
