Patent number: 10018686Abstract: An ultra-low noise sensor for magnetic fields comprises a mechanically resonant structure having a magnetized proof mass. The displacement of the proof mass due to a magnetic field provides a high resolution and highly amplified measurement of magnetic field fluctuations near the resonance frequency. A flux modulator may be used with the resonant structure to amplify magnetic fluctuations in a non-resonant frequency band. The resonant structure, combined with a high resolution readout device and a frequency-compensating numerical processor, can amplify magnetic fluctuations in a broad range of frequencies. A solenoid coil surrounding the resonant structure may be used to null the quasi-static earth's magnetic field and thereby increase the dynamic range of the sensor. Cryogenically cooling the resonant structure can improve the resolution of the sensor. A magnetometer that embodies features of the present invention is miniaturized and has improved amplification and resolution at room temperature.Type: GrantFiled: October 21, 2015Date of Patent: July 10, 2018Assignee: THE CHARLES STARK DRAPER LABORATORY, INC.Inventors: James Alan Bickford, Jonathan Jay Bernstein, Marc Steven Weinberg, Amy Elizabeth Duwel, Richard David Elliott, III, Ronald Edmund Gagnon, Jr., Joseph Michael Kinast, John Joseph LeBlanc, Thomas Francis Marinis, Jr., Michael Joseph Tomaino-Iannucci, William Joseph Trinkle, Jr.

Patent number: 9557174Abstract: Embodiments described herein provide for a method of modulating an input light beam of an interferometric fiber optic gyroscope (IFOG). The method includes intermittently jumping a phase step to suppress dead band. During a first cycle, a first cycle raw rate is stored and a feedback signal is generated based on a jumped phase step. During a second cycle, a second cycle raw rate is stored and a feedback signal is generated based on the jumped phase step. During a third cycle, a third cycle phase step is generated by accumulating the first cycle raw rate with a second cycle phase step, and a feedback signal is generated from the third cycle phase step. During a fourth cycle, a fourth cycle phase step is generated by accumulating the second cycle raw rate with the third cycle phase step, and a feedback signal is generated from the fourth cycle phase step.Type: GrantFiled: April 20, 2015Date of Patent: January 31, 2017Assignee: Honeywell International Inc.Inventors: William Joseph Trinkle, William Goethals

Patent number: 9557175Abstract: Embodiments described herein provide for a method of modulating an input light beam of an interferometric fiber optic gyroscope (IFOG). The method includes intermittently jumping a phase step to suppress dead band. If a bit flip was clocked into a digital to analog converter generating the feedback signal at the beginning of a cycle in which the jumped phase step is implemented, the method includes at least one of re-introducing a rate difference corresponding to the bit flip, altering the timing of the bit flip, or altering the timing of the generating a feedback signal based on the jumped phase step.Type: GrantFiled: April 20, 2015Date of Patent: January 31, 2017Assignee: Honeywell International Inc.Inventors: William Joseph Trinkle, William Goethals

Patent number: 9140551Abstract: Embodiments described herein provide a method of modulating an input light beam of a fiber optic coil of an IFOG. The method includes intermittently jumping the phase step of a feedback signal to suppress dead band. Jumping the phase step includes: creating a jumped phase step during a first cycle of the IFOG, the jumped phase step having a whole value configured to cause a phase jump in the feedback signal and a fractional value corresponding to the fractional value from a phase step of a cycle immediately preceding the first cycle. Jumping the phase step also includes generating the feedback signal from a sum of the bias modulation value and the jumped phase step.Type: GrantFiled: July 16, 2013Date of Patent: September 22, 2015Assignee: Honeywell International Inc.Inventors: William Joseph Trinkle, William Goethals

Patent number: 8174418Abstract: Systems and methods for improving resolution of low-noise signals in an analog-to-digital conversion circuit. A simple, low cost pseudo-noise generating circuit is disclosed that, when connected to the signal conditioning circuitry of A/D conversion circuit, adds pseudo-noise to an analog input voltage signal. Additional pseudo-noise is beneficial for improving the resolution of analog-to-digital conversion when oversampling and summing or averaging are used in post-conversion processing operations. The circuit is composed of a plurality of resistors configured in at least two parallel branches. An individually switchable voltage source output is connected to each branch. A resulting analog voltage can be measured at a common termination point for the branches, depending on the combination of switchable voltage source output turned on, and the branch to which the voltage output is applied.Type: GrantFiled: July 14, 2009Date of Patent: May 8, 2012Assignee: Honeywell International Inc.Inventors: Ernest Frank John Graetz, Kirby Kueber, William Joseph Trinkle
