| 20100313944 | WRAPPED OPTOELECTRONIC DEVICES AND METHODS FOR MAKING SAME - In various embodiments, optoelectronic devices are described herein. The optoelectronic device may include an optoelectronic cell arranged so as to wrap around a central axis wherein the cell includes a first conductive layer, a semi-conductive layer disposed over and in electrical communication with the first conductive layer, and a second conductive layer disposed over and in electrical communication with the semi-conductive layer. In various embodiments, methods for making optoelectronic devices are described herein. The methods may include forming an optoelectronic cell while flat and wrapping the optoelectronic cell around a central axis. The optoelectronic devices may be photovoltaic devices. Alternatively, the optoelectronic devices may be organic light emitting diodes. | 12-16-2010 |
| 20110146755 | VERTICALLY STACKED PHOTOVOLTAIC AND THERMAL SOLAR CELL - According to some embodiments, the present invention provides a novel photovoltaic solar cell system from photovoltaic modules that are vertically arrayed in a stack format using thin film semiconductors selected from among organic and inorganic thin film semiconductors. The stack cells may be cells that are produced in a planar manner, then vertically oriented in an angular form, also termed herein tilted, to maximize the light capturing aspects. The use of a stack configuration system as described herein allows for the use of a variety of electrode materials, such as transparent materials or semitransparent metals. Light concentration can be achieved by using fresnel lens, parabolic mirrors or derivatives of such structures. The light capturing can be controlled by being reflected back and forth in the photovoltaic system until significant quantities of the resonant light is absorbed. Light that passes to the very end and can be reflected back through the device by beveling or capping the end of the device with a different refractive index material, or alternatively using a reflective surface. The contacting between stacked cells can be done in series or parallel. According to some embodiments, the present invention uses a concentrator architecture where the light is channeled into the cells that contain thermal fluid channels (using a transparent fluid such as water) to absorb and hence reduce the thermal energy generation. | 06-23-2011 |

| 20100050255 | DETECTION AND SUPPRESSION OF SHORT MESSAGE SERVICE DENIAL OF SERVICE ATTACKS - A method, system, and medium are provided for suppressing a Short Message Service (SMS) induced Denial of Service (DoS) attack on a telecommunications network. A register is updated to include information relevant to SMS messages that are requested to be communicated by way of a wireless telecommunications network. The register includes information of the location where the target devices of SMS messages are located. The register is utilized to detect an SMS induced DoS attack. A trigger is communicated to an SMS router to enable a DoS mode that restricts the communication of SMS messages. In an exemplary embodiment, only those SMS messages identified as part of the DoS attack are restricted. | 02-25-2010 |

| 20090081249 | Bi-Functional Polymer-Attached Inhibitors of Influenza Virus - Antimicrobial compositions containing two or more antiviral agents coupled to a polymer and methods of making and using the compositions, are described herein. In one embodiment, two or more antiviral agents are covalently coupled to the polymer. Suitable antiviral agents include, but are not limited to, sialic acid, zanamivir, oseltamivir, amantadine, rimantadine, and combinations thereof. The polymer is preferably a water-soluble, biocompatible polymer. Suitable polymers include, but are not limited to, poly(isobutylene-alt-maleic anhydride) (PIBMA), poly(aspartic acid), poly(l-glutamic acid), polylysine, poly(acrylic acid), plyaginic acid, chitosan, carboxymethyl cellulose, carboxymethyl dextran, polyethyleneimine, and blends and copolymers thereof. In another embodiment, the compositions contain a physical mixture of polymer containing one antiviral agent and polymer containing a second antiviral agent. The compositions can be formulated for enteral or parenteral administration. Suitable oral/intranasal dosage forms include, but are not limited to, tablets, capsules, solutions, suspensions, emulsions, syrups, and lozenges. Suitable dosage forms for parenteral administration include, but are not limited to, solutions, suspensions, and emulsions. The compositions described herein are effective at treating a variety of infections, including viral infections such as influenza, while inhibiting or preventing the development of microbial resistance. | 03-26-2009 |

| 20110061116 | Animal Model of Synovial Sarcoma - Synovial sarcoma is an aggressive soft-tissue malignancy. Disclosed herein is an animal model of synovial sarcoma wherein one or more myogenic cells of the animal express recombinant SYT-SSX fusion polypeptide. Using this model, myoblasts were identified as a source of synovial sarcoma. Remarkably, within the skeletal muscle lineage, while expression of the oncoprotein in immature myoblasts leads to induction of synovial sarcoma with 100% penetrance, its expression in more differentiated cells induces myopathy without tumor induction. In addition, early widespread expression of the disclosed fusion protein disrupts normal embryogenesis, causing lethality. | 03-10-2011 |

| 20090037242 | System for Monitoring Periodic Processing of Business Related Data - A system stores and analyzes task processing statistical data and adaptively calculates the overall completion time of day-end processing of a set of standard jobs that create reports that need to be run at the end of each business day, for example, to extract and summarize key business data. In response different processing loads and task execution times occurring on different days. A system for monitoring periodic processing of business related data to provide reports at day end and other times, includes a repository of information. The information identifies multiple measured time durations required for processing business related data to provide a corresponding plurality of reports for individual days of multiple days. A computation processor determines an average time duration for processing business related data to provide an individual report by averaging measured time durations required for processing data to provide the individual report over multiple days. The computation processor uses the average time duration, together with a reference time of processing, to provide a predicted time of completion of processing to provide the individual report. A communication processor provides result data to a user. The result data represents the predicted time of completion of processing to provide the individual report. | 02-05-2009 |
