US Classification:

370353, 370354, 370400, 370401

Abstract:

In one embodiment, an apparatus may receive at least one call attribute of a public switched telephone network (PSTN) call initiated to a destination telephone number.

US Classification:

370353, 370352, 370400, 370401

Abstract:

A system for verifying VoIP call routing information. The system may include an apparatus integrated with a private branch exchange (PBX). The apparatus may store at least one call attribute of a public switched telephone network (PSTN) call initiated to a destination telephone number. The apparatus may verify a destination Voice-over-Internet-Protocol (VoIP) call agent for the destination telephone number based on demonstrated knowledge of the PSTN call. The apparatus may route a new call either over a VoIP network to the destination VoIP call agent or over a circuit switched network based on whether the destination VoIP call agent is verified for the destination telephone number.

G06F 1/04

US Classification:

380 44, 713168, 713171, 713503

Abstract:

A system may generate from a first value, based on rounding information, a first security key that matches a second security key whenever the first value and a second value from which the second security key is generated differ by less than a non-zero predetermined amount. The second security key may be generated from the second value rounded to a multiple of a rounding interval that is nearest to the second value. The rounding information may include a rounding direction indication. The rounding direction indication may indicate the direction in which the second value is rounded to the multiple of the rounding interval nearest to the second value.

International Classification:

G06F 15/16

US Classification:

709248

Abstract:

In one embodiment, a clock on a network device is initialized, and then a first timing message is received at the network device from a reference device having a first timestamp indicating when the first timing message was transmitted from the reference device. The network device may then determine and store a one-way delay from the first timestamp to a first time at which the first timing message was received at the network device. In response to restarting the clock, the network device may receive a second timing message from the reference device having a second timestamp indicating when the second timing message was transmitted from the reference device. The network device may then calibrate the clock such that a second time at which the network device received the second timing message is the second timestamp plus the stored one-way delay.

Assignee:

Diasense, Inc. - Pittsburgh PA

International Classification:

G01D 534

US Classification:

25023116

Abstract:

Disclosed is a radiation detector which includes at least one photoconductive detector and a modulator, which modulates in an on-off manner radiation passing to the photoconductive detector from a radiation source. A bias source is connected to one terminal of the photoconductive detector. A first amplifier is connected to the other terminal of the photoconductive detector, and a second amplifier receives an output of the first amplifier. A first phase detector detects the phase of modulation of the radiation source by the modulator and generates a reference signal relating thereto. A switch in the second amplifier changes, in response to the reference signal generated by the first phase detector, the second amplifier between an inverting state and a non-inverting state as the modulator changes the phase of modulation of the radiation.

Abstract:

A method is provided in which a call agent process that supports one or more Internet Protocol (IP) calls, stores to persistent memory a set of data associated with the one or more IP calls. An outage is detected affecting the one or more IP calls. Using the data retrieved from the persistent memory, the one or more IP calls are resynthesized using a device simulator process to simulate connectivity with endpoints that were participating in the one or more IP calls prior to the outage. After resynthesizing, depending on activity detected from devices associated with the one or more IP calls, the one or more IP calls are internally re-stitched/re-establishing (without signaling to endpoints) with the endpoints involved in the one or more IP calls, or the one or more calls are fully re-stitched/re-established by signaling an endpoint that was participating in the one or more IP calls.

Assignee:

Cognizant TriZetto Software Group, Inc. - Englewood CO

International Classification:

G06Q 10/10
G06Q 10/06

Abstract:

A processor-driven method provides a step-by-step process to assess an organization's ability to meet project and contract standards resulting from a negotiated contract. This assessment also highlights the most efficient path for performance and identifies strengths and weaknesses in the organizations abilities. The method can aid an organization's front line sale force in identifying resources that are optimal for use in a particular contract and can generate a back end work flow for implementation and tracking of program deliverables by administrators, program or contract managers and others based on the requirements of a negotiated project. The identification of key project phases and solutions and the ability to build process flows based on a library of the organization's operational information, e.g., resources, tools, artifacts, within intersections of the phases and solutions, allows an organization to determine best path to contract completion. The best path may optimize cost, time, and personnel.

International Classification:

G06F 11/20
H04L 29/06

Abstract:

In one embodiment, a network interruption may be determined to have occurred at an active node of a communication system, wherein the active node may be facilitating a first communication dialog between a first end point and a second end point. In response to the network interruption, a stateful switchover can be initiated between the active node and a standby node of the communication system. A reroute message may be transmitted to the first end point and the second end point, wherein the reroute message can instruct the first end point and the second end point to cease use of the first communication dialog and begin use of a second communication dialog, wherein the second communication dialog may be facilitated by the standby node.
