20100201820 | INTRUSION ALARM VIDEO-PROCESSING DEVICE - Binarization is performed using a threshold image obtained by multiplying a variation in each pixel value of an input image with a coefficient. Although the variation is time-averaged based on an update coefficient for each pixel, the update coefficient is switched depending on whether or not a relevant pixel belongs to the object. Subsequently, from the binary image, an initial detection zone is formed and a spatial filtering process is performed thereto. The spatial filtering process includes at least one of skeleton analysis processing, object mask processing, morphology processing, and section analysis processing. For a tracking zone, the temporal positional change thereof is tracked, and the noise is reduced. Some of the tracking zones are removed, and the remaining zones are integrated into a cluster, and furthermore the cluster selection is performed based on the dimensions in real space. | 08-12-2010 |

20090284660 | METHOD OF DETECTING OBJECTS - The invention, at the first frame, records the background, as the threshold of detection—constant image with the predetermining minimum threshold, and with each subsequent frame, corrects the background and threshold with formulas while producing the adaptation of a renewal—constant in each pixel depending on the presence of the detected object, defines the difference between the current frame and background, compares it with the threshold, combines elements exceeding a threshold into detection zones, performs rejection of the detection zones, divides the zones in order to separate shadows, forms a tracking zone, searches already-detected segment of objects, forming clusters of the tracking zones. The coordinates of the obtained rectangles are assumed as the coordinates of the objects located in the frame. | 11-19-2009 |

20110175244 | Configurations and Methods of Gas-Assisted Spray Nozzles - Contemplated configurations and methods are drawn to systems in which gas assisted spray nozzles are used to distribute a liquid phase in micron-sized droplets in a device effluent at a position upstream of a second device having multiple parallel flow paths for the effluent. Most preferably, the assist gas is a high-pressure gas phase that is generated in a process upstream of the device effluent, the first device is a hydrotreating or hydrocracking reactor or distillation column, and the second device is an air cooler or heat exchanger. | 07-21-2011 |

20110117729 | FLUID BED REACTOR - Fluidized bed reactor systems for producing high purity silicon-coated particles are disclosed. A vessel has an outer wall, an insulation layer inwardly of the outer wall, at least one heater positioned inwardly of the insulation layer, a removable concentric liner inwardly of the heater, a central inlet nozzle, a plurality of fluidization nozzles, at least one cooling gas nozzle, and at least one product outlet. The system may include a removable concentric sleeve inwardly of the liner. In particular systems the central inlet nozzle is configured to produce a primary gas vertical plume centrally in the reactor chamber to minimize silicon deposition on reactor surfaces. | 05-19-2011 |
