Patent number: 11327102Abstract: Aspects are generally directed to a compact and low-noise electric field detector, methods of operation, and methods of production thereof. In one example, an electric field detector includes a proof mass, a source of concentrated charge coupled to the proof mass, and a substrate having a substrate offset space defined therein, the proof mass being suspended above the substrate offset space. The electric field detector further includes a sense electrode disposed on the substrate within the substrate offset space and proximate the proof mass, the sense electrode being configured to measure a change in capacitance relative to the proof mass from movement of the proof mass in response to a received electric field at the source of concentrated charge. The electric field detector includes a control circuit coupled to the sense electrode and configured to determine a characteristic of the electric field based on the measured change in capacitance.Type: GrantFiled: August 25, 2020Date of Patent: May 10, 2022Assignee: THE CHARLES STARK DRAPER LABORATORY, INC.Inventors: James A.

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.

A substrate can be formed with a substantially planar surface, a substantially hemispherical cavity extending into the surface, an actuation electrode, and a plurality of sensing electrodes. A resonator formed from a substantially hemispherical shell can be suspended within the cavity by a stem coupling the center of the bottom of the cavity to the center of the bottom of the shell. An electronic processor can be configured to cause a voltage to be applied to the actuation electrode, receive signals from the sensing electrodes, and process the received signals to determine rotation of the MEMS gyroscope.Type: GrantFiled: October 31, 2012Date of Patent: August 23, 2016Assignee: The Charles Stark Draper Laboratory, Inc.Inventors: Jonathan Bernstein, Marc Steven Weinberg, Murali Chaparala, Peter G.
