Abstract: A social transaction management system may include an event transaction object, a personal transaction unit and a mobile application engine. The event transaction object is configured to track transactions of multiple users across multiple events, wherein the tracked transactions have defined transaction parameters. The personal transaction unit is communicatively coupled to at least one event transaction object and configured to determine an accounting of total transactions for each user per event based on associated event transaction object(s). The mobile application engine is communicatively coupled to the event transaction object(s) to create a communication portal between multiple users across multiple events. The system may create a transaction entry, transmit the transaction entry to a user device, receive an acknowledgement responsive to the notification from the user device and update the status of the transaction entry on both the receiving and sending user devices.

Abstract: The present disclosure generally relates to methods of preparing nicotine and resolving R,S nicotine to enrich the (S)(?) enantiomer. The method may comprise combining N-methyl-2-pyrrolidone or a salt thereof with a nicotinate compound in the presence of a solvent and a strong base to form 1-methyl-3-nicotinoyl-2-pyrrolidone or a salt thereof; and reducing the 1-methyl-3-nicotinoyl-2-pyrrolidone or salt thereof in solution with Na2S2O4 to produce racemic nicotine or salt thereof. Resolving the racemic nicotine (or other enantiomeric mixture) may comprise combining the nicotine with (?)-O,O?-di-p-toluoyl-L-tartaric acid (L-PTTA).

Abstract: An achievement system tracks users' offline activities and awards achievements to users for participation in particular offline activities. The achievements that are awarded for particular activities and/or to particular users may be sponsored by merchants, who may compensate an achievement system provider for the opportunity to sponsor the achievements. To award users achievements, the users' offline activities are tracked. When a user participates in an offline activity for which achievements are available, the user is awarded an achievement. The achievement may be stored in an achievement profile for the user. In some embodiments, achievements earned by users may be converted into other benefits and alternative awards.

Abstract: A gaming environment is provided by an MVP gaming system provider in which “most valuable player” (MVP) gamers may compete. MVP gamers may be identified using achievements, gamer scores, game play during sanctioned gaming events, or other indicia of game skills. The MVP gamers may be sponsored by advertisers, and the MVP gamers' avatars may be branded based on sponsorship during gaming events. The sponsorships may be brokered by the MVP gaming system provider. Some gaming events may be sanctioned gaming events that are coordinated by the MVP gaming system provider and “televised” to allow viewers to watch the gaming events. Tutorials from MVP gamers may also be provided to gamers for viewing to assist in their game play. Further, gamers may be able to rent the avatars of MVP gamers for use during their game play.

Abstract: Methods, systems, and computer-readable media for ranking products using multiple data sources are provided. A computerized ranking system includes a ranking engine, loaders, and a presentation component. The ranking engine calculates a score for each product based on multiple counts logged by data sources. Loaders communicatively connected to the ranking engine provide the counts to the data sources. The presentation component generates a ranked product list for display on client devices in response to requests for a list of popular products.

Abstract: The subject disclosure relates to an improved electronic commerce and advertising platform that aggregates transaction data from merchants and consumers. A set of enhanced scenarios built on the platform span both the online and offline transactional and advertising universe to the benefit of all participants of the electronic commerce and advertising platform. Transactional data and profile data are used to customize search and advertising results for specific users or groups of users. Transactional data and profile data can be leveraged within a social network to recommend activities, such as which restaurants come recommended by friends of a user.

Abstract: Client computer systems can add authenticity to electronic payment requests through use of software license keys. In one implementation, for example, a payment request originating from a requestor (e.g., client computer system, point of sale terminal) sends one or more license key identifiers to a payment validating entity along with the payment details of the requested transaction. In addition to reviewing the payment transaction request and payment details for fraud, one or more payment validating entities can also review the one or more license key identifiers to determine if the request originates from as client computer system using valid software, or using potentially invalid or otherwise pirated software. In one implementation, the payment validating entities can deny a transaction originating from software from which validity cannot be determined. The payment validating entities can also, or alternatively, store information about the requestor for subsequent reporting purposes.

Abstract: A pressure plate provides a trapped pressure relief groove oriented along the line of action of mating gears in a gear pump. The groove communicates the fluid trapped between the gear teeth with both the inlet and outlet, thereby reducing high squeezed pressures and lowering hydraulic noise levels. Noise suppression is apparent at all speeds, and is particularly apparent at high pump operating speeds.
