Patent number: 8295501Abstract: The performance of an echo canceller is assessed using a) a test signal launched from originating test equipment and b) a simulated echo of the test signal launched from terminating test equipment. The launch of the simulated echo signal is timed in such a way that it arrives at the tandem echo canceller(s) at a particular point in time relative to the arrival of the test signal, at the tandem echo canceller(s), when the tandem echo canceller(s) is (are) not able to cancel the simulated echo signal. The latter thus arrives uncanceled at the target echo canceller. The launch of the simulated echo signal is further timed in such a way that it arrives at the target echo canceller at a point in time relative to the arrival of the test signal, at the target echo canceller, when the target echo canceller is able to cancel the simulated echo signal.Type: GrantFiled: December 15, 2008Date of Patent: October 23, 2012Assignee: AT&T Intellectual Property I, L.P.Inventors: James H James, Wallace F.

Patent number: 8068412Abstract: A connection in an optical communication system is routed over a sequence of cross-connects and aggregated links comprising multiple links. A different link selection algorithm is used for service provisioning than is used for restoration, i.e., after a cable cut or other failure or incident has made one or paths in the network suddenly unavailable. In particular, a special link selection algorithm called the Interleave algorithm is used for restoration different from the well known Best-Fit algorithm used for provisioning. The Interleave algorithm substantially reduces the probability of glare while maintaining near-optimum capacity utilization.Type: GrantFiled: January 9, 2008Date of Patent: November 29, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: Bruce G.

Patent number: 7983619Abstract: Intra-cell upstream data forwarding is utilized in a wireless network such as a wireless local area network. A network forwarding path is determined based on the signal strength of an access point signal received at client stations within the network, referred to as the OASS. In particular embodiments, a station that is either originating or forwarding a frame inserts its own OASS into the frame before transmitting it and a client station that receives a frame forwards it only if its own OASS exceeds the frame-enclosed OASS, illustratively by at least a predetermined amount.Type: GrantFiled: December 8, 2009Date of Patent: July 19, 2011Assignee: AT&T Intellectual Property II, L.P.Inventor: Lusheng Ji

Patent number: 7932777Abstract: A switching amplifier drives balanced piezoelectric or other capacitive or reactive loads with a minimum physical electronics volume, enabling a compact arrangement that can combine amplifier and transducer at the same physical location. Power supply current is minimized by using two or more transducers driven with phase-shifted signals, resulting in stored energy being cycled between the transducers rather than being carried over the power supply lines for storage in a power supply. Auxiliary power supply capacitors to store energy coming out of the load can thus be minimized. The modulation scheme puts the switching frequencies in common-mode while the baseband signals are differential mode. The common-mode switching frequency signals are blocked from the loads by a common-mode inductor. The common-mode inductor can be physically small as a result of the large baseband load currents being in differential mode.Type: GrantFiled: February 20, 2004Date of Patent: April 26, 2011Inventors: George Gustave Zipfel, Jr., Christie Lewis Zipfel

Patent number: 7911978Abstract: A topology discovery process is used to discover all of the links in an ad hoc network and thereby ascertain the topology of the entire network. One of the nodes of the network, referred to as the coordinator, receives the topology information which can then be used to, for example, distribute a routing table to each other node of the network. The process has a Diffusion phase in which a k-resilient mesh, k>1, is created by propagating a topology request message through the network. Through this process, the nodes obtain information from which they are able to discern their local neighbor information. In a subsequent, Gathering phase, the local neighbor information is reported upstream from a node to its parents in the mesh and thence to the parents' parents and so forth back to the coordinator. The robustness of the Diffusion phase is enhanced by allowing a node to have more than one parent as well as by a number of techniques, including use of a so-called diffusion acknowledgement message.Type: GrantFiled: April 29, 2008Date of Patent: March 22, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: Ranveer Chandra, Christof Fetzer, Karin Hogstedt

Patent number: 7806053Abstract: At least some of the segments of a segmented rod projectile are provided with a mechanism that causes them to divert away from the projectile's original line of flight after the segments are separated during flight to the target. That mechanism is illustratively a notched flare. The segments illustratively divert in a predetermined dispersion pattern. In order to ensure that each segment flies in the desired direction after separation, the disclosed projectile includes a mechanism that, just prior to segment separation, arrests spin of the projectile. Thus the segments are essentially non-spinning after separation and thus the desired diversion will not be counteracted by post-separation spin of the segments.Type: GrantFiled: August 9, 2006Date of Patent: October 5, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Hartley Hughes King, Thomas Louis Menna, Lawrence Steven Romero

Patent number: 7783473Abstract: Classification of sequences, such as the translation of natural language sentences, is carried out using an independence assumption. The independence assumption is an assumption that the probability of a correct translation of a source sentence word into a particular target sentence word is independent of the translation of other words in the sentence. Although this assumption is not a correct one, a high level of word translation accuracy is nonetheless achieved. In particular, discriminative training is used to develop models for each target vocabulary word based on a set of features of the corresponding source word in training sentences, with at least one of those features relating to the context of the source word. Each model comprises a weight vector for the corresponding target vocabulary word.Type: GrantFiled: December 28, 2006Date of Patent: August 24, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Srinivas Bangalore, Patrick Haffner, Stephan Kanthak

Patent number: 7672331Abstract: Switches within a telecommunications network exchange so-called available bandwidth messages, each of which advertises how much bandwidth remains unassigned on a respective link. The network is of a type in which circuits are provisioned with various predefined numbers of time slots (equivalent to bandwidth). The sending of an available bandwidth message for a given link is triggered by a change in the number of time slots available on that link if that change results in a change in the number of circuit bandwidths that can be accommodated by that link for a newly provisioned circuit.Type: GrantFiled: February 25, 2004Date of Patent: March 2, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Bruce Gilbert Cortez, Sanja Durinovic-Johri, Pravin Kumar Johri, John Paggi, Simon S.
