Publication number: 20040126783Abstract: A method for preparing a nucleic acid component of a sample for amplification includes contacting the sample with a porous support that deactivates a nucleic acid amplification inhibitor component of the sample and directing a fluid through the porous support, whereby the nucleic acid component of the sample is directed through at least a portion of the porous support and is separated from the support, thereby preparing the nucleic acid component for amplification. The sample is separated from raw sample components through means that include a magnetic substrate. An apparatus suitable for conducting the method of the invention also is described.Type: ApplicationFiled: July 10, 2003Publication date: July 1, 2004Applicants: Massachusetts Institute of Technology, Smiths Detection-Edgewood, Inc.,Inventors: Laura T.

Publication number: 20040101125Abstract: A method of negotiating a call capability between signalling points in a telecommunications system. The method comprises sending a capability preference or prioritised list of preferences from an originating signalling point to a terminating signalling point or signalling transfer point, at the Call Control level. A capability acceptance is returned from the terminating signalling point or signalling transfer point to the originating signalling point at the Call Control level, if the terminating signalling point or signalling transfer point accepts a preference sent by the originating signalling point.Type: ApplicationFiled: October 15, 2003Publication date: May 27, 2004Inventors: Leslie Graf, Paul Hollis, David De Nicolo, Christian Groves, Ian Rytina, Juan Noguera-Rodriguez, Mark Hollis, Nebosja Dikic, Stephen Terrill, Sune Ramstrom, Lars Kari, Barry Dingle

Patent number: 6681009Abstract: A method of signalling in a telecommunications network comprises generating signalling messages at an Application Part or a User part of an originating signalling point, the messages having a maximum length of 272 octets. The generated signaling messages are transferred to a Message Transfer Part layer 3 (MTP3) of the originating signalling point, and on the basis of the destination signalling point of the received signalling message, it is determined whether or not the message is to be transmitted over an NNI-SAAL signalling link. If the message is to be transmitted over an NNI-SAAL signalling link, the message is transferred to an NNI-SAAL part of the originating signalling point. If the message is not to be transmitted over an NNI-SAAL signalling link, the message is transferred to an MTP2 part of the originating point.Type: GrantFiled: May 26, 2000Date of Patent: January 20, 2004Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Leslie Graf, Christian Groves, Juan Noguera-Rodriguez, Mark Hollis, Stephen Terrill

Publication number: 20030195981Abstract: In a method for the control of a connection in a communication network comprising a plurality of nodes (MSC, TSN, MG), a connection (CO) is established stepwise between nodes (MSC, TSN, MG). At least two of the nodes (MSC, TSN, MG) are adapted to insert an entity into the connection (CO), the entity affecting the connection quality, or to remove an entity affecting the connection quality from the connection. An indicator is forwarded between nodes controlling the connection (CO) wherein the indicator indicates whether the connection (CO) comprises an entity affecting the connection quality. A node which decides to insert an entity into the connection or remove an entity adjusts the indicator accordingly before forwarding it to a further node (MSC, TNS, MSC′) controlling the connection (CO). A node (MSC, TSN, MSC′) controlling the connection (CO) checks the value of the indicator when it performs a decision to insert or remove an entity.Type: ApplicationFiled: April 1, 2003Publication date: October 16, 2003Inventors: Leslie Graf, Phil Hodges, Mark Hollis

Patent number: 5155561Abstract: The base layer of a power permeable base transistor is formed as comb structures with grating teeth of the combs extending into active regions of semiconductor material. Extended active regions are separated by inactive regions over which collector contacts extend. Large devices have digitated base layers. The comb structures are fabricated by sputtering a uniform layer of tungsten and forming a nickel mask over the tungsten by both X-ray and photolithography techniques. The tungsten exposed by the nickel mask is then etched to leave the comb structures.Type: GrantFiled: January 5, 1988Date of Patent: October 13, 1992Assignee: Massachusetts Institute of TechnologyInventors: Carl O.
