Patent number: 6839422Abstract: A method and apparatus for efficiently utilizing resources in a switched telephone network by providing call treatment at the closest available resource to the calling party preventing holding up network connection through to the terminating location if resources are not available at call termination equipment to handle a call. The selected calls are locally parked pending the availability of service termination resources to handle the call. The availability of service resources at the termination is determined before a selected call is extended through the network. Advantageously while the call is parked call treatment discrimination can be performed.Type: GrantFiled: July 18, 2002Date of Patent: January 4, 2005Assignee: NewStep Networks, Inc.Inventors: L.

Patent number: 6766009Abstract: A method and system for correlating information retrieved from a data network, with a telephone call initiated by an initial address message (IAM) at a multi-line facility, such as a call center or a voice access server (VAS), hinges on extracting an identifier string inserted into the user-user-interface field of the IAM, and accompanying the information. The information is used to perform an enhanced service feature which may include aiding the selection of an internal line at call center's call distributor, or the selection and customization of delivery of a service feature, at a VAS. The information may also be displayed at a display terminal associated with a call center agent handling the call.Type: GrantFiled: March 7, 2002Date of Patent: July 20, 2004Assignee: NewStep Networks Inc.Inventors: L. Lloyd Williams, Alexander Markman, David Edward Johnston

Publication number: 20040116660Abstract: The invention provides a process for the selection of HIV-1 subtype (clade) C isolates, selected HIV-1 subtype C isolates, their genes and modifications and derivatives thereof for use in prophylactic and therapeutic vaccines to produce proteins and polypeptides for the purpose of eliciting protection against HIV infection or disease. The process for the selection of HIV subtype isolates comprises the steps of isolating viruses from recently infected subjects; generating a consensus sequence for at least part of at least one HIV gene by identifying the most common codon or amino acid among the isolated viruses; and selecting the isolated virus or viruses with a high sequence identity to the consensus sequence. HIV-1 subtype C isolates, designated Du422, Du 151 and Du 179 (assigned Accession Numbers 01032114, 00072724 and 00072725, respectively, by the European Collection of Cell Cultures) are also provided.Type: ApplicationFiled: September 12, 2003Publication date: June 17, 2004Inventors: Robert Edward Johnston, Salim Abdool Karim, Lynn Morris, Ronald Ivar Swanstrom, Carolynn Williamson

Patent number: 6724876Abstract: A system and method provide a call service features in response to call control information conveyed by a monitored bearer channel in a telecommunications network. A bearer channel monitor captures the call control information and relays the information to a call control application server. The call control application server analyzes the call control information, and provides call control instructions to a call control node that operates in the telecommunications network to effect the call service. The call control node serves as one or more virtual switching points in the network to directly control call routing without disconnecting a called or calling party, unless required as part of a service feature. Control from a center of the telecommunications network provides rapid and efficient call control without use of edge devices or duplication of bearer channels in the network.Type: GrantFiled: March 2, 2001Date of Patent: April 20, 2004Assignee: RevD Networks, Inc.Inventors: L.

Publication number: 20040010986Abstract: A method of seismic retrofitting a concrete structure includes removing material from a portion of the concrete structure by irradiating the portion with a laser beam having a laser energy density. The method further includes positioning a stabilization structure in proximity to the portion of the concrete structure. The method further includes attaching the stabilization structure to the portion of the concrete structure, whereby the stabilization structure provides structural support to the concrete structure.Type: ApplicationFiled: November 27, 2002Publication date: January 22, 2004Inventors: Kenneth Joe Breyer, Bradley Steven Johnson, George Edward Johnston, Martin Johnson, Elwood Smietana, Ronald Hamburger, Michael J.

Publication number: 20030235281Abstract: A method and apparatus for authenticating calling parties prior to call connection at a service facility uses the correlation of the call with a security message received over a data network. The correlation is made possible with an encoded string inserted into a field (such as the user-to-user information (UUI) field) of a call set-up signaling message used to initiate the call, and a correlate of the encoded string inserted into the security message. The authentication is provided at an authentication site that is logically separate from the service facility. The call is first connected to the authentication site, an authentication procedure is preferably selected and customized, and then performed. A security message is generated that includes information related to the client and the encoded string. The call is then disconnected from the authentication site, and reconnected to the service facility.Type: ApplicationFiled: June 24, 2002Publication date: December 25, 2003Applicant: BELL CANADAInventors: L.

Patent number: 5044055Abstract: A clamping mechanism is provided to prevent movement of the rotatable stock carrier of a multiple spindle bar machine after it has rotated into position for the machining operation. The clamping mechanism comprises a controllable locking pin to engage indexing pin slots on the stock carrier, a passive pressure brake located opposite the locking pin, and a hydraulically actuated pressure brake in the same quadrant as the locking pin. The hydraulically actuated brake clamps the carrier against the passive brake, and in combination with the locking pin holds the carrier against movements caused by the forces of the machining tools. The hydraulic brake is released by a programmable controller to allow intended rotation of the carrier to a new position.Type: GrantFiled: May 17, 1990Date of Patent: September 3, 1991Assignee: Parker Hannifin CorporationInventors: Richard F. Howarth, Robert A. DiDomizio, W. Edward Johnston

Patent number: 4462535Abstract: This invention relates to improved apparatus and process for manufacture of tunnel modules and tunnel sections used to build underwater tunnel tubes. A collapsible fixture is used to roll up a steel plate into a cylindrical shell. Cables wrapped around channels on the outer ends of fixtures are used to roll up the fixture along the plate. After the fixture with the shell on it is placed on pedestals for further fabrication, cables placed in the channels are used to rotate the shells. After the fixture is collapsed within the shell, it is raised up by pedestal lifting mechanisms, and wheels provided on the fixture are lowered into place to aid in removal of the fixture from the shell, and onto a roll-out table. Roller mechanisms are also used to aid in the removal of the fixture from the shell. The roll-out table is situated between two sets of pedestals and used in the removal of fixtures from single modules or sets of modules.Type: GrantFiled: August 26, 1983Date of Patent: July 31, 1984Assignee: AMCA International CorporationInventors: Edward Johnston, Morton Jacobs, Melvin E.
