| 20090317879 | Use of selection pressures to enable microbial biosynthesis of polyhydroxyalkanoates from anaerobic degradation products - A method for inexpensive and efficient PHA biosynthesis includes operating a sequencing bioreactor in alternating phases of nutrient deprivation and carbon feedstock deprivation to select for robust PHA-producing microbes. Preferably, the bioreactor is operated in a non-sterile manner with mixed cultures of methanotrophs. The method also preferably uses periodic biomass-wasting (PHA harvesting) at the end of the carbon feed phase, gradually lengthening the time period of carbon deprivation phase to create a penalty for rapid PHA degradation and incentive for PHA accumulation. Also, bacterial enrichment cultures may be introduced periodically. The PHA-accumulating bacteria are preferably grown on common anaerobic degradation products, specifically volatile fatty acids, such as acetate and propionate, and methane gas. The PHA has useful applications in bioplastics and other products. | 12-24-2009 |

| 20110159556 | Use of hydroxyalkanoic acids as substrates for production of poly-hydroxyalkanoates by methane-oxidizing bacteria - A method of biosynthesis of polyhydroxyalkanoates (PHA) is provided that includes providing a type II methanotrophic bacteria, and disposing the type II methanotrophic bacteria in an unbalanced growth condition, where the unbalanced growth condition includes a nutrient-deficient media and a hydroxyalkanoic acid, and where the nutrient-deficient media has an absence of an essential nutrient required for cell replication of the type II methanotrophic bacteria. | 06-30-2011 |
| 20110160067 | High throughput system for isolation, growth, and detection of lipid inclusions in bacteria - A method of high throughput growth and quantitative analysis of microorganisms is provided that includes providing a microtiter plate growth and gas delivery system having well plates disposed for growth of the microorganisms, and providing a spectroscopic screening system disposed to analyze lipid inclusions of the microorganisms. | 06-30-2011 |

| 20110112257 | Bacterial poly(hydroxy alkanoate) polymer and natural fiber composites - A biocomposite is produced from natural fiber fabrics embedded in a matrix of biosynthetic polyhydroxy-alkanoate (PHA) polymers. The PHA is synthesized using aerobic microbial biosynthesis using mixed bacterial cultures and a feedstock containing anaerobic degradation products such as methane and volatile fatty acids derived from microbial biodegradation of organic waste materials, which may include waste biocomposites. Monomers may be added to the synthesized PHA polymer to control mechanical properties of the resulting biocomposite. The natural fibers and/or PHA may be pretreated using various techniques to improve the bond between the fibers and the PHA resin matrix and water absorption resistance of the fibers. The composite may be a laminate of treated and untreated fabric layers, or differently treated layers, to achieve good in-service performance as well as rapid and/or optimal biogas production when taken out of service and put in an anaerobic environment to degrade. | 05-12-2011 |

| 20080236045 | Safety gate system having an electronic display - A safety gate system having an electronic display for seamless integration into a barrier with electronic display capabilities. The safety gate system includes a post and a gate hinged to the post. The gate face and post carry electronic display modules which appear when the gate is closed, as continuous with and seamlessly integrated into the display of the barrier. Preferably, the hinges are four-bar hinges, most preferably two sets of paired four-bar hinges. The safety gate also includes a lower chase or sill which allows both signal wiring and power to pass under the gate. Braced rear legs compensate for the cantilever forces of the gates when open. A latch, preferably an electromagnetic latch, auto-releases in response to a pre-set sufficient force level, such as arising crowd surge forces, being applied to the gate, as well as being remotely releasable. | 10-02-2008 |

| 20100312865 | ASYNCHRONOUS UPDATE OF VIRTUALIZED APPLICATIONS - A determination is made as to whether an updated image for an outdated virtualized application is available on a server. If it is determined that the updated image is available, then a background download operation configured to retrieve the updated image from the server is initiated. Another determination is made as to whether the outdated virtualized application is being utilized. After the background download operation is complete, if it is determined that the outdated virtualized application is not being utilized, then the outdated virtualized application is transformed to a current virtualized application by replacing at least a portion of the outdated virtualized application with the updated image. The outdated virtualized application and the current virtualized application are configured to be executed on the computer without installation on a computer. | 12-09-2010 |

| 20090133013 | Creating Virtual Applications - Embodiments are provided to create a virtual application or suite of virtual applications. In an embodiment, a system is configured to create a virtual package which includes information that can be used in a hosted virtual application environment. The system can provide bits of a virtual package based in part on user demand for an application or certain application functionality. In one embodiment, a system includes a sequencer component which can create a virtual package which includes information associated with setup-time and run-time changes made to a computing device. The sequencer component can use a number of extensible markup language (XML) files to create the virtual package. Other embodiments are available. | 05-21-2009 |
| 20100333085 | Streaming Optimized Virtual Application Images - Embodiments provide an optimized virtual application or suite of virtual applications, but are not so limited. In an embodiment, components of a system are configured to generate an optimized virtual package that can be used in a virtual application streaming environment. Components of the system can provide bits of the optimized virtual package based in part on scenario mappings associated with a user action and/or an application or application feature. In one embodiment, a client virtualization handler can operate to download byte ranges of an optimized virtual package including re-prioritizing byte range download operations as part of streaming virtual application functionality over a computing network. | 12-30-2010 |

| 20110208508 | Interactive Language Training System - An interactive language training system allows practice word/phrase lists customized by the user for training. The customized lists may include words/phrases extracted from content sources based upon user selections. Extraction may include analysis of the content sources to determine word/phrase frequency, topic, and/or other parameters. A video sample of a student speaking a word/phrase is compared with video examples of a speaker and provides visual feedback for pronunciation and articulation. Progress is monitored for each word/phrase on the list, and performance feedback provided. Communication, such as voice or video chat may be established between the student and a speaker to provide for additional practice. | 08-25-2011 |
