  • Publication number: 20130166330
    Abstract: A seamless travel hive engine automatically stores a user's travel-related information in a seamless travel hive repository, and may generate experience marks for displaying and sharing a user's travel-related information. The system provides a continuity of the travel-related user experience through time by storing, updating, aggregating, and sharing information among multiple users and across multiple devices and applications, including social networks. The seamless travel hive engine continuously and dynamically integrates a seamless travel hive repository, travel reservation module, experience mark manager module, comparison module, tagging module, alert module, and consumer travel-related applications, and may provide a platform for a continuous cross-device travel booking flow.

  • Patent number: 5192687
    Abstract: This process makes it possible to prepare a compound of controlled enantiomeric purity, D-P or L-P respectively, from a substrate S consisting of the oxidized form of the corresponding D/L-P racemate or of the said D/L-P racemate, or else of the optical isomer which is the inverse of that which it is wished to prepare. In accordance with this process, the said substrate S, the said D/L-P racemate or the optical isomer inverse of that which it is wished to prepare, respectively, is introduced into an electrochemical reactor together with an oxidoreductase enzyme capable of catalyzing the oxidation of the optical isomer which is the inverse of that which it is wished to prepare; a potential difference is applied between the electrodes in order to perform the nonstereospecific cathodic reduction of the said substrate S until the isomer having the required enantiomeric purity is obtained; and the cosubstrate of the said enzyme is regenerated by anodic oxidation in the said electrochemical reactor.
