Patent number: 8139910Abstract: A method of controlling an ultra-short pulse system is described comprising controlling an optical power within the ultra-short pulse system and control-system controlling a width of an optical pulse. In some embodiments, the method also comprises tuning a compressor by controlling a number of passes of the optical pulse through a Bragg grating to control the width of the optical pulse output from the compressor. In other embodiments, the method may comprise tuning a multi-pass stretcher by controlling a number of passes of the optical pulse through a loop of the multi-pass stretcher to control the width of the optical pulse output from the multi-pass stretcher. A method of controlling an ultra-short pulse system may also comprise accessing a control system from a remotely located command station, communicating status information from the control system to the command station, and communicating information from the command station to the control system.Type: GrantFiled: October 27, 2008Date of Patent: March 20, 2012Assignee: Raydiance, Inc.Inventors: Andrew D. Stadler, David Goldman, Mark Farley, Michael M. Mielke, Kyungbum Kim, Laurent Vaissié, Robert G. Waarts, Michael J. Cumbo

Patent number: 8135050Abstract: A chirped pulse amplification system includes one or more polarization compensator configured to compensate for polarization altering elements with the chirped pulse amplification system. The polarization compensator is responsive to a sensor configured to provide feedback to the polarization compensator. In some embodiments, the chirped pulse amplification system further includes a controller configured to automatically adjust the polarization compensator responsive to the sensor. The sensor is optionally a power sensor.Type: GrantFiled: July 19, 2006Date of Patent: March 13, 2012Assignee: Raydiance, Inc.Inventors: Andrew D.

Publication number: 20080205330Abstract: Systems and methods are provided for compressing and decompressing session initiation protocol (SIP) messages. A serializer and parser compress and decode SIP data structures according to a tokenized binary protocol. The compression/decompression protocol uses tokens that represent message elements of the internal data structures that define SIP messages. Tokens may be assigned to message elements based on various design requirements. Some tokens provide sufficient generality to encode any legal SIP message, while others are highly optimized to match the elements found in most common SIP messages. For those elements requiring specific strings, three dictionaries are defined. Two of the dictionaries are static and are never transmitted; the third dictionary is dynamic and contains strings found only in the specific message.Type: ApplicationFiled: October 31, 2007Publication date: August 28, 2008Applicant: CORE MOBILITY, INC.Inventors: Andrew D.

Patent number: 7089027Abstract: A method and system that helps to reduce delay in initiating communication sessions. A network entity operates as a signaling agent on behalf of a terminating node and positively acknowledges a session initiation request on behalf of the terminating node without first receiving a positive acknowledgement from the terminating node. For example, the network entity may first send an alert message to the terminating node and then positively respond to the session initiation request before receiving from the terminating node a response to the alert message. As another example, the network entity may first positively respond to the session initiation request and then send an alert message to the terminating node. This arrangement can advantageously allow the session setup process to continue, without first waiting for an actual positive acknowledgement from the terminating node.Type: GrantFiled: August 7, 2003Date of Patent: August 8, 2006Assignee: Sprint Spectrum L.P.Inventors: David Welch, Christopher M. Doran, Konstantin Othmer, Andrew D. Stadler
