Title: Power supply for light emitting diode roadway lighting fixture
Inventor: WINTERS ALAN SHAWN
IPC: H05B44/00
Filed: 2010-01-26
Abstract: A high efficiency light emitting diode power supply for roadway lighting fixtures is provided. The power supply enables conditioning and monitoring of input power and monitors LEDs current to ensures consistent performance of the LED by changing a power correction factor. The LED output can also be adjusted based upon age or external input parameters and by modifying the power correction factor value. In addition, the LED output can be dimmed, turned down in output to a lower level at any time of night for a prescribed duration in order to further save energy. This dimming function uses a programming scheme that keeps track of the "seasons" (summer, fall, winter and spring) so that time of night is tracked accurately all year long.

Abstract: Conducting poly(3,4-ethylenedioxythiophene) films are prepared upon solvent removal using an easily processable metastable solution of monomer and oxidant. This method allows the casting and spin-coating of films on conducting as well as insulating substrates with conductivities as well as optical and redox properties similar to those reported for chemically (vapor phase) and electrochemically synthesized thin films. Morphological characterization of spin coated poly(3,4-ethylenedioxythiophene) films suggest that they are smooth, uniform and free of pinholes on the micron scale. These films show conductivities in the range of 0.03 to 5 S/cm.

Abstract: The method and system describes monitoring and modeling the hydraulic fracturing of a reservoir. The microseismic events caused by hydraulic fracturing on a reservoir are captured by sensor arrays. The data captured by the sensor arrays are then analyzed to determine the source radius, and seismic moment tensor of microseismic events caused by the hydraulic fracturing. This information is then combined with a seismic velocity model to arrive at a discrete fracture network showing at least the orientation, source radius, and source mechanism of each microseismic event. This discrete fracture network is then used to determine the stimulated surface area, stimulated volume, and point of diminishing returns for the hydraulic fracturing process. Hydraulic fracturing engineers can use the algorithms to monitor the well and/or determine well completion.
