20100210204 | ELECTRICALLY CONDUCTIVE CONFINED SPACE VENTILATOR CONDUIT FORMED OF CONDUCTIVE POLYMER, ELECTRICAL GROUNDING CIRCUIT FOR VENTILATION SYSTEMS USING SAME, AND METHODS OF USING AND FORMING SAME - An electrically conductive confined space ventilation conduit formed of a substantially rigid non-metallic conductive material, such as plastic, and a related process for ventilating an enclosure accessed by a manhole or other port. In one embodiment, the conduit has a pair of outer cylindrical sections and a central section having a cross-sectional shape of a crescent or a segment of a circle where it passes through a port to provide a minimum of obstruction for men and equipment passing through the port. Intermediate sections of varying cross-section connect the central section to the cylindrical outer sections so that the outer sections are offset from the axis of the manhole. The central section is preferably configured to obstruct no more than about 10 percent of a standard manhole opening, while causing either no air flow rate reduction, or a reduction of no more than about 10 percent as compared to the flow rate through a cylindrical conduit similar to said outer sections. The conduit is preferably formed of a conductive or electrically dissipative polyethylene polymer material to allow static electricity to be conducted from the conduit to ground. In a preferred embodiment, a connecting device for connecting the conduit to electrical ground is connected to the conduit. A grounding circuit kit and method of grounding the conduit is also disclosed. | 08-19-2010 |

20100243179 | MULTI-FOLD PANEL ASSEMBLIES - A closure assembly of an opening in a building has at least two mutually pivoted panels mounted with the pivot axis at least substantially vertical. The panels are movable between a closed condition whereby the panels provide at least a partial closure of the opening in or substantially parallel to the plane of the opening, and an opened condition whereby the panels, mutually disaligned by having pivoted towards each other, are substantially clear of the plane. A proximate panel is pivoted by a vertical pivot axis substantially in the plane of the opening adjacent a vertical periphery of the opening. The distal region of the distal panel is supported by a supporting runner. The supporting runner is guided by a support track which is skewed with respect to the plane of the opening and which spaces the supporting runner out of the plane of the opening at the vertical periphery. | 09-30-2010 |

20100027569 | UV DIODE-LASER MODULE WITH OPTICAL FIBER DELIVERY - A diode-laser module includes a diode-laser delivering radiation having a wavelength less than 450 nm and located a housing. Focusing optics focus the radiation into a single-mode optical fiber located in the housing. The radiation is focused through an end-cap bonded to the single-mode fiber and having a diameter greater than the core-diameter of the single-mode fiber. The length of the end-cap is selected cooperative with the focusing optics such that the beam intensity at the entrance end of the end-cap is below a level that would cause photodecomposition of any gaseous hydrocarbons in the housing. | 02-04-2010 |

20080256420 | ERROR CHECKING ADDRESSABLE BLOCKS IN STORAGE - Provided are a method, system, and article of manufacture for error checking addressable blocks in storage. Addressable blocks of data are stored in a storage in stripes, wherein each stripe includes a plurality of data blocks for one of the addressable blocks and at least one checksum block including checksum data derived from the data blocks for the addressable block. A write request is received to modify data in one of the addressable blocks. The write and updating the checksum are performed in the stripe having the modified addressable block. An indication is made to perform an error checking operation on the stripe for the modified addressable block in response to the write request, wherein the error checking operation reads the data blocks and the checksum in the stripe to determine if the checksum data is accurate. An error handling operation is initiated in response to determining that the checksum data is not accurate. | 10-16-2008 |
20090119463 | SYSTEM AND ARTICLE OF MANUFACTURE FOR DUMPING DATA IN PROCESSING SYSTEMS TO A SHARED STORAGE - Provided are a system and article of manufacture for dumping data in processing systems to a shared storage. A plurality of processing systems receive a signal indicating an event. Each of the processing systems write data used by the processing system to a shared storage device in response to receiving the signal, wherein each processing system writes the data to the shared storage device. | 05-07-2009 |
20120195524 | VALIDATING STORED COPIES OF DATA IMAGES TO LOAD INTO MEMORY - Provided are a method, system, and article of manufacture for validating stored copies of data images to load into memory. An image of data is maintained in a memory, wherein the image in the memory includes a generation number. The image in the memory is written to at least two copies of the image to storage locations in response to a first event, wherein the generation number for the image in the memory is stored in the storage locations having the copies of the image. A check generation number is stored in a storage location. The image is loaded from at least one of the copies of the image in one of the storage locations to the memory in response to a second event The generation number for the image loaded into the memory. The check generation number is incremented in response to the second event. The generation numbers for the copies of the image in the storage locations and the check generation number are used to validate the copies of the image. | 08-02-2012 |

20140310159 | REDUCED FRAUD CUSTOMER IMPACT THROUGH PURCHASE PROPENSITY - A method, system and computer program product for reduced fraud customer impact through purchase propensity is disclosed. A probability estimate of spending by a consumer in a merchant transaction category is computed based on historical transaction data and consumer profile data, and a propensity score for the merchant transaction is generated. The propensity score represents a propensity for the consumer to conduct the merchant transaction. The propensity score is combined in a fraud model operating in a real-time transaction stream. The fraud score can be adjusted in accordance with the propensity score. | 10-16-2014 |
