Patent number: 7272280Abstract: An optical coupler for measuring mean wavelength of a broadband optical source is described. Sensitivity of the optical coupler to variations of refractive index and coupler length is minimized. The sensitivity to the variations of the refractive index is minimized by making a difference between the group refractive indices of the symmetric and asymmetric propagation modes approximately constant and independent of the refractive index. The sensitivity to the variations of the coupler length is minimized by selecting the coupler length that makes output powers from two waveguides to the first order insensitive to its length. This selection is possible for broadband optical sources.Type: GrantFiled: December 16, 2004Date of Patent: September 18, 2007Assignee: Honeywell International Inc.Inventors: Bogdan Szafraniec, Charles Lange

Publication number: 20070103691Abstract: A clock system for a fiber optic gyroscope is provided that includes a highly-tunable clock for the bias modulation and a separate asynchronous high-speed clock for the photodetector sampling.

Patent number: 7085948Abstract: A method, apparatus and computer program product are provided for implementing time synchronization correction in computer systems. A service processor includes a battery-backed hardware clock, and a hypervisor includes a hypervisor system clock. A common timer resource is accessible by the hypervisor and the service processor. To synchronize the battery-backed hardware clock and the hypervisor system clock, the common timer resource is used to measure the latency in the communication medium between the hypervisor and the service processor. The latency is then added onto the time value received in time of day messages between the hypervisor and the service processor for time synchronization correction in the computer systems.Type: GrantFiled: April 24, 2003Date of Patent: August 1, 2006Assignee: International Business Machines CorporationInventors: Gary Dean Anderson, Adam Charles Lange-Pearson, Thomas Joseph Warne

Publication number: 20060126072Abstract: A fiber optic gyroscope (FOG) includes a sensing coil with a particular magnetic sensitivity magnitude and direction with respect to the geometric axis of the sensing coil. The FOG also includes a plurality of magnetic compensators.

Patent number: 6798523Abstract: A fiber optic fault detector and generic fiber optic sensor system for detecting breaks in an optical fiber using a low coherence interferometric technique. The system comprises a light source configured to produce light traveling along the optical path, a modulator optically coupled to the light source configured to modulate at least a portion of the light as a function of a modulation signal, a detector optically coupled to the modulator configured to produce a detector output based upon a sensed intensity of the light, and an electronic array configured to receive the detector output and determine the optical fault. The low coherence interferometric technique allows for detection of a fault in the fiber with a minimal amount of test equipment and with higher measurement sensitivity and resolution. The system may alternatively include a transducer, positioned in place of the fiber under test, having a response which changes in reflective or optical path length.Type: GrantFiled: December 4, 2001Date of Patent: September 28, 2004Assignee: Honeywell International Inc.Inventors: Charles Lange, Scott Anson, Dick Ang
