Title: Smart routing synchronization system and methods for socializing a synthetic rebroadcast and group stream
Inventor: LEEKLEY GREGORY
IPC: H04L47/2416
Filed: 2015-04-23
Abstract: Smart routing synchronization systems socialize a synthetic rebroadcast or group stream for enabling members of a user group to (re)broadcast select content to other members of the user group and collaboratively curate content delivery. The systems are based on a content-identification process and further a process for (re)broadcasting content. These processes are cooperable among a group of member clients each of which are in communication with at least two content sources. The synchronization process identifies select content and directs delivery of the content from an optimal resource for each member client via a smart routing protocol. The (re)broadcast process prompts delivery of the select content to members of the user group from a content origination member of the group, and group members are thereby able to simultaneously access the content for the purpose of providing a content-based platform for social interaction.

Abstract: PCT No. PCT/GR92/00017 Sec. 371 Date May 18, 1993 Sec. 102(e) Date May 18, 1993 PCT Filed Sep. 17, 1992 PCT Pub. No. WO93/05947 PCT Pub. Date Apr. 1, 1993An apparatus and method are disclosed for extruding a product which comprises a longitudinal component, e.g. a tubular sheet and/or longitudinal filaments in a circular array, and transverse filaments which follow a helical path relative to the longitudinal component, whereby the product may consist of a lattice or a reinforced sheet material. The transverse filaments are formed by cooperation between two die parts (101; 102) to which relative movement is imparted so that one part (102) performs a rocking motion progressing around a circular path to influence the extrusion orifice, without rotation of the die parts. The extrusion orifice may comprise an annular slot defined between two die members (106; 108) of the first die part (101) which is held stationary, while the second die part (102) extends around the first part and has an edge for alternatively opening and at least partially closing the slot at each point along its annular extent in response to the relative circular rocking movement imparted to the second part (FIG. 7). Alternatively, the extrusion orifice may be defined between cooperating frusto-spherical surfaces (4, 8) of the two die parts (3, 7) with the inner die part having a groove (9) which is alternately exposed and concealed due to circular rocking motion imparted to this die part (FIG. 1).
