20110309686 | GENERATING DC ELECTRIC POWER FROM AMBIENT ELECTROMAGNETIC RADIATION - At least certain embodiments describe methods, apparatuses, and systems for converting energy from electro-magnetic (EM) radiation into electric power using a simultaneous collector of ambient radio frequencies (SCARF) circuit. In one embodiment this is done by capturing EM radiation from a plurality of ambient signals using an array of antennae where each signal has a resonant frequency and aggregating the ambient signals to generate an aggregated signal having a single frequency with greater AC power than the AC power of each of the plurality of ambient signals individually. The single frequency can be produced by either the sum of the resonant frequencies of the ambient signals or the difference between the resonant frequencies of the ambient signals. The aggregated signal is then converted into useable electric power using a rectifying circuit such that for every incremental increase in the AC power of the aggregated signal, there is a corresponding exponential increase in DC power at the output of the rectifying circuit. | 12-22-2011 |

20090255855 | APPARATUS AND METHOD FOR SEPARATING MATERIALS - A material separator for separating at least two different materials of differing densities and/or sizes of particles. The material separator generally includes a tank containing a flocculent, a circulation system for circulating flocculent within the tank and a pair of conveyors for moving two different materials out of the tank. The tank may include an upper chamber and a lower chamber. At least a portion of each of the conveyors is located in the upper chamber to catch materials fed into the flocculent. Each of the conveyors may include a mesh belt that permits the flocculent to flow through the conveyor. The tank may include a clean out valve that permits fines and other debris accumulated within the upper chamber to pass into the lower chamber. The flocculent circulation assembly may include a nozzle that can be constructed in various configurations to create flows of flocculent of various velocities and trajectories. In one embodiment, the lower chamber includes a drag line assembly that removes fines and other accumulated debris from the lower chamber. | 10-15-2009 |

20080277587 | METHOD AND APPARATUS FOR CORRECTING SCATTERING IN SPECT IMAGING - A method and apparatus for correcting scattering in SPECT I-123 imaging. The method generally includes: accessing list mode data for a plurality of pixels corresponding to a first SPECT I-123 image generated using a gamma camera; generating a raw energy spectrum for at least some of the pixels utilizing the acquired list mode data; acquiring a gamma camera model corresponding to the gamma camera; utilizing the gamma camera model and an iterative algorithm to apply a first scattering correction to the raw energy spectrum; utilizing a Compton window to apply a second scattering correction to the raw energy spectrum; and generating a correction table with the corrected raw energy spectrum. | 11-13-2008 |
