| 20080216649 | Liquid-phase and vapor-phase dehydration of organic/water solutions - Processes for dehydrating an organic/water solution by pervaporation or vapor separation using fluorinated membranes. The processes are particularly useful for treating mixtures containing light organic components, such as ethanol, isopropanol or acetic acid. | 09-11-2008 |
| 20090004713 | Membrane-augmented distillation with pressure change to separate solvents from water - Processes for removing water from organic solvents, such as ethanol. The processes include distillation in two columns operated at sequentially higher pressure, followed by treatment of the overhead vapor by one or two membrane separation steps. | 01-01-2009 |
| 20090057224 | Dehydration processes using membranes with hydrophobic coating - Processes for removing water from organic compounds, especially polar compounds such as alcohols. The processes include a membrane-based dehydration step, using a membrane that has a dioxole-based polymer selective layer or the like and a hydrophilic selective layer, and can operate even when the stream to be treated has a high water content, such as 10 wt % or more. The processes are particularly useful for dehydrating ethanol. | 03-05-2009 |
| 20090277326 | Gas separation processes using membrance with permeate sweep to recover reaction feedstocks - A gas separation process for treating off-gas streams from reaction processes, and reaction processes including such gas separation. The invention involves flowing the off-gas across the feed side of a membrane, flowing a sweep gas stream, usually air, across the permeate side, and passing the permeate/sweep gas mixture to the reaction. The process recovers unreacted feedstock that would otherwise be lost in the waste gases in an energy efficient manner. | 11-12-2009 |
| 20100051441 | Membrane-augmented distillation with compression to separate solvents from water - Processes for removing water from organic solvents, such as ethanol.

| 20100236404 | GAS SEPARATION PROCESS USING MEMBRANES WITH PERMEATE SWEEP TO REMOVE CO2 FROM COMBUSTION GASES - A gas separation process for treating flue gases from combustion processes, and combustion processes including such gas separation. The invention involves flowing the flue gas stream to be treated across the feed side of a membrane, flowing a sweep gas stream, usually air, across the permeate side, then passing the permeate/sweep gas to the combustor. | 09-23-2010 |
| 20110005272 | Process for separating carbon dioxide from flue gas using parallel carbon dioxide capture and sweep-based membrane separation steps - A gas separation process for treating flue gases from combustion processes, and combustion processes including such gas separation. The invention involves routing a first portion of the flue gas stream to be treated to a carbon dioxide capture step, while simultaneously flowing a second portion of the flue gas across the feed side of a membrane, flowing a sweep gas stream, usually air, across the permeate side, then passing the permeate/sweep gas to the combustor. | 01-13-2011 |

| 20090240652 | AUTOMATED COLLECTION OF HUMAN-REVIEWED DATA - The embodiments of the present invention provide methods and systems for automated collection of human-reviewed data. Requesters send data to be reviewed by humans (or data requests) to a data processing system, which is in communication with one or more systems for collecting human-reviewed data (HRD). The methods and systems discussed enables the data processing system to work with one or more of the systems for collecting HRD). In one embodiment, between the data processing system and the systems for collecting HRD are wrappers, which stores parameters specific to the data requests and libraries for transforming the data requests to human intelligent tasks (HITs) specific to each HRD system. The data processing system also includes a number of components that facilitate transforming data requests into HITs, sending the HITs to the HRD collection systems, receiving HRD, and analyzing HRD to improve the quality of collected HRD. | 09-24-2009 |
| 20100228597 | Transferring Targeting and Marketing Information from an Online Advertisement System - An online advertising system integrates third party agents to permit the third party agents to participate in auctions to bid on a per opportunity basis. An advertising exchange module receives requests for opportunities to serve online advertisements to users. In response, an advertising exchange module applies one or more business rules to determine third party agents that qualify to serve the online advertisement. A bid gateway module generates and transmits requests for bids to the third party agents. The bid gateway module then receives bids from the third party agents in response to the requests for bids. The advertising exchange module then selects an advertisement based on the bid. The online advertisement exchange system provides a unified marketplace to permit integrator networks to bid on both ads pursuant to guaranteed contracts and ads not subject to guaranteed contracts (e.g., non-guaranteed ads). The online advertisement system further includes traffic management to allow the third parties to regulate bid requests sent from the online advertisement system. In some embodiments, the online advertising system caches bids, to efficiently implement the per opportunity auction, and transmits information, such as targeting information, to the third party agents to aid in the third party agents' formulation of bids. | 09-09-2010 |

| 20110078013 | RATE-BASED AUCTION-FORMAT ONLINE ADVERTISEMENT MANAGEMENT - Methods and systems are provided for use in connection with an online advertising exchange. Methods are provided in which an auction format is utilized. However, generally, selection and pricing is rate-based and based on near-term forecasting. As such, the selection and pricing does not match specific, immediately available serving opportunities and advertisement inventory. Methods are provided which are in some ways analogous to providing futures—like mini-contracts on an advertising exchange, in which selection and pricing are decoupled from fulfillment of the mini-contracts in the form of serving of advertisements. This can allow auction format advantages while yet allowing forecasting, offline processing and relatively inexpensive operation costs. | 03-31-2011 |
