Patent number: 8037404Abstract: A markup language document representing computing elements of a computing architecture, such as data storage elements of a data storage architecture, is constructed and analyzed. A first computing element contained by a second computing element is represented; a first tag of the document corresponding to the first computing element is nested within a second tag of the markup language document corresponding to the second computing element. A non-containing/contained relationship from the first computing element to a third computing element is also represented; a pointer tag of the document corresponding to the data access path is nested within the first tag, and references a third tag of the document corresponding to the third computing element. Get-pointer-node and get-child-node application programming interfaces for the markup language are called to traverse among containing/contained relationships. Pointer tags are followed to traverse among non-containing/contained relationships.Type: GrantFiled: May 3, 2009Date of Patent: October 11, 2011Assignee: International Business Machines CorporationInventors: Bernhard J.

Publication number: 20110170571Abstract: A laser device includes an optical resonator, a microwave driven discharge device, and a source for a second gas. The microwave driven discharge device is disposed relative to the optical resonator. The microwave driven discharge device operates at a discharge power and gas flow rate to produce a selected amount of energetic singlet oxygen metastables flowing in the direction of the optical resonator. The second source for the second gas is disposed between the optical resonator and the microwave driven discharge device. The second gas reacts with the selected amount of energetic singlet oxygen metastables to form an excited species in an amount sufficient to support lasing of the excited species in the optical resonator.Type: ApplicationFiled: September 14, 2010Publication date: July 14, 2011Inventors: W.

Patent number: 7103471Abstract: A method and apparatus for providing dead reckoning position data, orientation, and heading of a person is disclosed. The apparatus uses an algorithm that automatically determines the appropriate set of navigation functions for personal navigation based upon the orientation of the apparatus. Dead reckoning is accomplished by combining electronic heading and motion signals from human ambulation. Individual orientation and human motion measurement is accomplished with motion sensing devices. In one implementation of the invention, a navigation device provides different heading, position, and/or orientation functionality depending on whether the navigation device is affixed to the user in a vertical position or horizontal position, or the navigation device is not affixed to the user.Type: GrantFiled: September 17, 2003Date of Patent: September 5, 2006Assignee: Honeywell International Inc.Inventors: Robert W.

Patent number: 6472869Abstract: A diode laser-pumped magnetometer includes a diode laser that emits a polarized pumping laser beam with resonant optical radiation; and a K-cell through which a magnetic field is manifested from an independent source, the K-cell containing atoms with a dipole experiencing a torque due to the magnetic field. The atoms are excited by the resonant optical radiation of the pumping laser beam and periodically emitting a response radiation as they return to ground state such that the response radiation includes photons that indicate one unit of angular momentum indicative of the torque due to the magnetic field. Finally, a photodetector serves as a means for measuring the response radiation of the K-cell to indicate thereby a measure of the magnetic field in the K-cell from the independent magnetic source.Type: GrantFiled: June 18, 2001Date of Patent: October 29, 2002Assignee: United States of America as represented by the Secretary of the Air ForceInventors: Bernard L.

Patent number: 6307890Abstract: The present invention provides a system for multiplexing DARC encoded source channels using an FM subcarrier, wherein the system includes a plurality of channels. Each channel within the plurality of channels is coupled to its own DARC encoded source channel. Within each channel of the system, the DARC encoded source channel is block encoded to produce parity and data bytes. The parity bytes and data bytes are separately trellis code modulated to form a first and second set of complex signals, respectively. A first digital modulator modulates a first set of orthogonal signals using the first set of complex signals. A second digital modulates a second set of orthogonal signals using the second set of complex signals.Type: GrantFiled: December 6, 1999Date of Patent: October 23, 2001Assignee: Cue CorporationInventors: Timothy F.
