Abstract: Synchronous content sharing of media assets via an object data model propagated through a star network or a mesh network. Each user device updates a local object data model including information on the status of the media asset delivery, to achieve synchronization with the source data. Updates to the local object data model may be the result of direct connection between a user device and an application server via a network, or the result of indirect connections through peers in mesh networks, where the local object data model is shared through hops between peers in the mesh network if the direct connection is unavailable.

Abstract: The present invention relates to optionally substituted compounds of the formula I or a salts thereof; wherein R1 is O or S, R2 is hydrogen or a C1-C10 organic group attached by a carbon atom, X is H, O, OO, S or SS R3 is absent where X=H, is hydrogen or is a hydroxyl or thiol protecting group, R4 is a hetero- or homo-cyclic aryl group, optionally substituted with a further group R5, one Y group is S and the other is either H (in which case only one R6 group is present) or S; and R6 is, independently, an organic group of molecular weight up to around 500 amu. The invention also provides compositions comprising such compounds and methods of treatment comprising administration of such compositions.

Abstract: The present invention provides optionally substituted compounds of the formula I or salts thereof; wherein R1 is O or S when double bonded to the ring or is OH, SH, or a protected equivalent, when single bonded to the ring, R2 is hydrogen or more preferably an C1-C10 organic group attached by a carbon atom, X is H, O, OO, S or SS R3 is absent where X?H, is hydrogen or is a hydroxyl or thiol protecting group, R4 is a hetero- or preferably homo-cyclic aryl group, optionally substituted with a further group R5 and groups T1 are each, independently, absent, hydrogen or an S—R6 group, where any/each R6 is independently an organic group of molecular weight up to around 500 amu. The invention further provides a method for the synthesis of such compounds and a method of treatment comprising administering such compounds to a mammalian subject.

Abstract: There is described a system and method for locating, and optionally monitoring the status of, a mobile entity in a given area fitted with a radio beacon. In one embodiment, the system features a network of bi-directional radio beacons which transmit on the same frequency at random intervals. A method for processing and relaying unique message identifiers throughout the system is disclosed which allows the vicinity of the mobile entity to be determined from any beacon in the network.
