Patent number: 9143333Abstract: A system and method for multicast transmission are disclosed. In one embodiment, a virtual exchange network including interconnected nodes is embedded within a network. A sender is disposed in communication with a root node and receivers are disposed in communication with a set of edge nodes. The sender publishes a packetized data stream to which the receivers subscribe. The packetized data stream is promulgated by implicit signaling through optimum virtual exchange network connections from the sender through the virtual exchange network to the receivers. The interconnected nodes, responsive to receiving the published packetized data stream, are adapted to multicast N instances of the published packetized data stream to N recipients selected from the group consisting of receivers and other of the interconnected nodes.Type: GrantFiled: July 22, 2014Date of Patent: September 22, 2015Assignee: Upload Technologies S.A.Inventors: Robert E. Nimon, David E. Espenlaub, Francis Dinha, James Yonan

Patent number: 7864991Abstract: A system and method for assisting a visually impaired individual are disclosed. In one embodiment, when the visually impaired individual encounters a situation with an obstacle, the visually impaired individual employs a first wireless device to transfer audiovisual information about the situation to an assistant with a second wireless device. The assistant analyzes the rendered audiovisual information and provides audio information to the visually impaired individual which presents a solution to the obstacle.Type: GrantFiled: April 6, 2007Date of Patent: January 4, 2011Assignee: ESPRE Solutions Inc.Inventors: David E.

Patent number: 6574327Abstract: In a telecommunications network (1), a signal transfer point (10) receives an Initial Address Message (IAM) generated by an originating service switching point (12) according to a call from an originating subscriber (20). The IAM includes a destination number associated with a destination subscriber (22). If the destination number has not been ported, the signal transfer point (10) sends a return message to the originating service switching point (12) indicating that no changes are to be made to the IAM. As a result, the originating service switching point (12) forwards the IAM to a destination service switching point (13) for processing of the call. If the destination number has been ported, the signal transfer point (10) performs a local number portability look-up in a database (24). The signal transfer point (10) obtains a redirection number from the database (24) for transfer in a return message to the originating service switching point (16).Type: GrantFiled: July 10, 2002Date of Patent: June 3, 2003Assignee: Alcatel USA Sourcing, L.P.Inventors: David M.

Patent number: 4635187Abstract: In a multiprocessing system, a method of efficiently maintaining a program process active while also ensuring that the process is deactivated when no longer needed. One or more subordinate processes are linked to a controlling process. Each subordinate process has an associated overall timer. As long as the controlling process keeps sending periodic keep-alive messages to a subordinate process, the associated overall timer is prevented from timing out. When the controlling process stops sending keep-alive messages, the associated overall timer times out and the subordinate process is deactivated.Type: GrantFiled: December 19, 1983Date of Patent: January 6, 1987Assignee: AT&T Bell LaboratoriesInventors: Donna M.
