20130026920 | Iodine Fueled Plasma Generator System - An iodine fueled plasma generator system includes a plasma generator. At least one storage vessel is configured to store condensed phase iodine therein. A heating device proximate to the storage vessel is configured to create iodine vapor from the condensed phase iodine. A propellant management subsystem is configured to deliver the iodine vapor to the plasma generator. A feedback control subsystem is responsive to one or more of plasma generator discharge current, the pressure of the iodine vapor, and/or the temperature of the iodine vapor configured to regulate the flow rate of the iodine vapor to the plasma generator. | 01-31-2013 |
20130093350 | AUTONOMOUS METHOD AND SYSTEM FOR MINIMIZING THE MAGNITUDE OF PLASMA DISCHARGE CURRENT OSCILLATIONS IN A HALL EFFECT PLASMA DEVICE - An autonomous method for minimizing the magnitude of plasma discharge current oscillations in a Hall effect plasma device includes iteratively measuring plasma discharge current oscillations of the plasma device and iteratively adjusting the magnet current delivered to the plasma device in response to measured plasma discharge current oscillations to reduce the magnitude of the plasma discharge current oscillations. | 04-18-2013 |

20100207527 | Multi-functional power supply for a hall thruster - A multi-functional power supply system for a Hall thruster including a thruster assembly for providing a plasma discharge and a cathode assembly for providing electrons. The cathode assembly includes an emitter, a keeper with a current limiting device, and a heater. A magnetic field source is operatively associated with the cathode assembly for generating a magnetic field to control the discharge. A plasma discharge circuit creates a plasma and accelerates the plasma to produce thrust. A power supply is connected to the keeper and the plasma discharge circuit and is connected to the heater through a switching device responsive to a predetermined condition for interrupting the power to the heater and simultaneously enabling the power supply to deliver power to the keeper and the plasma discharge circuit to initiate production of thrust. | 08-19-2010 |

20100003087 | System for Distributing Poultry Litter Below the Soil Surface - Biodegradable solid soil amendment material such as poultry litter may be disposed of in soil using an apparatus which includes a soil cutter for cutting a trench and a dispenser for transporting the material and simultaneously grinding or shearing the material and distributing it to the trenches in the soil. The receptacle includes a plurality of troughs across its bottom surface, each having an outlet at one end thereof, and corresponding screw augers therein for distributing and transporting the material to the outlets. As the material is transported toward each of the outlets by the augers it is crushed or ground to a small size. This apparatus allows the material to be dispensed through the multiple outlets at a substantially steady, uniform rate. | 01-07-2010 |

20090059028 | Imaging Standard Apparatus and Method - A standard used to test imaging systems is imaged by a digital camera which expresses the image of the standard as a plurality of pixels having associated intensities. A computer automatically finds the image of the standard in the image and quantitatively compares intensities of pixels of a subsequent image of the standard to the first image to discern changes indicative of malfunction. A set of images of the standard may be collected and compiled to develop standard data, such as average of median values, that can be used to test imaging apparatus. The standard may be provided with a plurality of types of imaging standards occupying sub-areas that produce a different photoresponse to a plurality of different light sources. A fluorescent standard may be included that has a plurality of different fluorescence levels. Multiple sub-areas of the same type may be distributed over the surface area of the standard to measure the photoresponse in several areas and also to facilitate locating all sub-areas of the standard, e.g., multiple white squares may be distributed over the standard that may be identified by thresholding. The results of testing via the standard may be graphically displayed. | 03-05-2009 |
