20120261125 | Horizontal In-Well Treatment System and Source Area Bypass System and Method For Groundwater Remediation - The application relates to a sustainable and green remedial approach for in situ remediation. The system and method use directionally drilled horizontal wells filled with granular reactive media generally installed in the direction of groundwater flow for groundwater remediation. “Flow-focusing” behavior is leveraged to capture and passively treat proportionally large volumes of groundwater in situ. The system and method perform well in low hydraulic conductivity environments where the success of other in situ remediation methods is controlled by aquifer injectability. Reactive media are selected according to the contaminants to be treated and site characteristics. Energy conservation and other considerations result in considerable cost savings compared to current in situ remediation systems. Also disclosed is a source area bypass system comprising one or more horizontal wells, constructed in a manner to allow unimpacted or cleaner groundwater to bypass a nonaqueous phase liquid zone or high-concentration source area of contamination and discharge downgradient. Reactive media may or may not be used in a source area bypass system. In some configurations, groundwater pumps may be installed to enhance performance. Core elements of green remediation according to the United States Environmental Protection Agency are achieved. | 10-18-2012 |

20100053298 | METHOD AND SYSTEM FOR CORRECTING THE LINEARITY ERROR IN ELECTROPHOTOGRAPHIC DEVICES - The invention describes a method and system for correcting linearity error of an electrophotographic device with a reduced number of lenses. The method and system insert additional time-slices in the data being processed by the electrophotographic device. The additional time-slices are inserted in the data in a predefined order based on a plurality of random numbers. The insertion of additional time-slices corrects the linearity error of the electrophotographic device. | 03-04-2010 |

20120281996 | LASER SCAN UNIT FOR AN IMAGING DEVICE - A system and method for reducing scan line jitter in laser scan systems employing a rotating mirror, including a controller for determining a unique time delay for each mirror facet and controlling laser sources so that video provided by each laser source is delayed in a scan line by the unique time delay corresponding to the mirror facet used in creating the scan line. The controller computes a facet map signature vector corresponding to each mirror facet matches the signature to a previously stored signature and assigns distance offset data to the mirror facets based upon the matching. | 11-08-2012 |
20130121713 | Laser Scan Unit for an Imaging Device - A system and method for reducing scan line jitter caused by facet cut variation in scan systems employing a plurality of laser sources and a sensor for generating the timing for the laser sources. The system includes a controller for determining a unique time delay for each facet of the rotating mirror, and controlling the laser sources so that video provided by each laser source is delayed in a scan line by the unique time delay corresponding to the facet of the rotating mirror used in creating the scan line. | 05-16-2013 |
