Abstract: Aspects relate to causing one or more signals to be detectable within a live event such that devices that record at least a portion of the event also record the one or more signals. The signals can be used for later processing and categorization of received recordings in order to associate the recordings with the event. Further actions can be performed based on the association. Such actions include digital rights management, crowd-sourced experiences, and categorization of the event for searching and retrieval purposes.

Abstract: A system and method are provided for creating, managing, rendering and delivering digitally synthesized products that can be automatically generated as a function of variable attributes provided by a variety of sources. The system can include design tools for creating workflows that describe the rules for dynamically creating digital products; licensing system to manage product licensing; distributed synthesis systems for generating products; location based services to manage location/time specific products; sharing services for transferring products; web services for composing and sharing products; mobile applications for composing and sharing products; notification services for notifying participants of system state changes; databases for managing the components of the system; extension services for externally developed system extensions; API services for external management and utilization of the system; and e-commerce services for paying or collecting fees for usage of the system by contributors or users.

Abstract: The present invention relates to a process for the preparation of benzothiazepine derivatives of general formula I ##STR1## wherein R stands for hydrogen and acetyl or of acid addition salts thereof in which a corresponding compound of general formula II ##STR2## in which R has the same meaning as above is reacted with 2-(dimethylamino)-ethyl chloride in a biphasic system of water and a non-combustible aliphatic polychlorinated hydrocarbon solvent in the presence of calcium hydroxide or of barium hydroxide. The process is advantageously performed at a temperature between 15.degree. and the refluxing temperature of the aliphatic polychlorinated hydrocarbon solvent. The process is optionally performed in the presence of a suitable quaternary ammonium halide.
