Publication number: 20180081880Abstract: Systems and methods are provided for ranking electronic information based on determined similarities. In one aspect a set of unique features are determined from a collection of electronic objects. A graph is constructed in which electronic object are represented as object nodes and determined features are represented as feature nodes. The object nodes are interconnected by a weighted edge to at least one feature node. Scores for the object nodes and the feature nodes are computed using a determined set of anchor nodes and a determined weighted adjacency matrix. The object nodes and the feature nodes of the graph are ranked and displayed based on the computed scores. In one aspect, the scores and the ranks for the object nodes and the feature nodes are dynamically updated and displayed based on user preferences.Type: ApplicationFiled: September 16, 2016Publication date: March 22, 2018Applicants: Alcatel-Lucent Canada Inc., Alcatel-Lucent USA Inc.Inventors: William S.

Patent number: 9374787Abstract: A method is provided for use in a mobile communication terminal configured to support a plurality of applications, wherein each application is executed by performing one or more tasks. The method includes, in response to a scheduling request from an application, obtaining an indication of power supply condition at a requested run-time of at least one of the tasks. The method further includes obtaining a prediction of a rate of energy usage by the task at the requested run-time, estimating, from the predicted rate of energy usage, a total amount of energy needed to complete the task, and making a scheduling decision for the task. The scheduling decision comprises making a selection from a group of two or more alternative dispositions for the task. The selection is made according to a criterion that relates the run-time power-supply condition to the predicted rate of energy usage by the task and to the estimate of total energy needed to complete the task.Type: GrantFiled: February 10, 2011Date of Patent: June 21, 2016Assignee: Alcatel LucentInventors: Adriaan J. de Lind van Wijngaarden, Nachi K.

Patent number: 7660321Abstract: There is provided a system and method for prioritizing session initiation protocol (“SIP”) messages. More specifically, in one embodiment, there is provided a method of prioritizing SIP messages in a network, the method comprising receiving SIP messages in a first order from one or more other servers of the network, wherein each of the received SIP messages comprises one or more priority indicators, scheduling the received SIP messages into a second order based on one or more of the priority indicators, and processing the scheduled SIP messages in the second order.Type: GrantFiled: March 1, 2006Date of Patent: February 9, 2010Assignee: Alcatel-Lucent USA Inc.Inventors: Mauricio Cortes, Nachi K. Nithi, Anwar I. Walid

Publication number: 20090109856Abstract: A system and method for reducing switching overhead in a communication network and a web-based server incorporating the system or the method. In one embodiment, the system includes: (1) an optimization engine configured to receive input data describing trunks, switches and traffic demands in at least a portion of the communication network and arrange connections between the trunks and switches such that the traffic demands are satisfied and such that a switch load or cost is reduced and (2) a report generator associated with the optimization engine and configured to produce a report containing a modified configuration having the reduced switch load or cost.Type: ApplicationFiled: January 8, 2009Publication date: April 30, 2009Applicant: Alcatel-Lucent USA, IncorporatedInventors: Nachi K. Nithi, Carl J. Nuzman, Benjamin Y.C. Tang

Publication number: 20070270166Abstract: Location-based services are provided in a communication system comprising at least a portion of at least one wireless network. In one aspect of the invention, users associated with respective mobile user devices are separated into at least a first group of users of a first benefit class of a location-based service and a second group of users of a second benefit class of the location-based service. Location information is obtained for the mobile user devices, with the location information being obtained more frequently for the mobile user devices of users in the first group than for the mobile user devices of users in the second group. At least one message is controllably delivered to a given one of the mobile user devices based on the location information.Type: ApplicationFiled: May 19, 2006Publication date: November 22, 2007Inventors: Karl Georg Hampel, William Michael MacDonald, Nachi K.

Patent number: 7283745Abstract: Techniques and systems for design of optical switch arrays so as to minimize power requirements are described. A design system includes a computer system hosting a design program. The design program receives parameters for the switch array, including a number N of outputs required, and either a maximum number L of stages allowed or maximum and average power requirements allowed. If power requirements are used as parameters, the design program uses N and the power requirements to compute the value of L. The design program then constructs a minimum power sequence of L switches or N switches, whichever is less. If N is less than L+1, N outputs are present and the array is complete. If N is greater than L+1, the design program then adds switches one at a time to the minimum power switch path of the array, until the array provides N outputs.Type: GrantFiled: March 31, 2003Date of Patent: October 16, 2007Assignee: Lucent Technologies Inc.Inventors: Krishnan Kumaran, Timothy O. Murphy, Nachi K. Nithi, Carl Jeremy Nuzman, Gaylord W. Richards

Patent number: 7050668Abstract: Techniques and systems for control of optical switching arrays are described. A switch array controller according to an aspect of the present invention operates so as to achieve reduced power consumption and maintain crosstalk within acceptable limits. Various rules are applied in order to insure that the desired criteria are met. In order to reduce transient effects, switching from one output to another is accomplished in a sequence chosen to maximize the number of transitions occurring in those portions of the array not carrying a signal, and to minimize the number of transitions that occur in portions of the array carrying the signal. Transitions are made in the portion of the array to which the signal will be directed, then a switch is transitioned between the old and new signal paths, and finally further transitions are made in the portion of the array within which the signal was previously directed.Type: GrantFiled: June 19, 2003Date of Patent: May 23, 2006Assignee: Lucent Technologies Inc.Inventors: Krishnan Kumaran, Nachi K.
