Nanomechanical electric and electromagnetic field sensor

Title: Nanomechanical electric and electromagnetic field sensor

Abstract

The present invention provides a system for detecting and analyzing at least one of an electric field and an electromagnetic field. The system includes a micro/nanomechanical oscillator which oscillates in the presence of at least one of the electric field and the electromagnetic field. The micro/nanomechanical oscillator includes a dense array of cantilevers mounted to a substrate. A charge localized on a tip of each cantilever interacts with and oscillates in the presence of the electric and/or electromagnetic field. The system further includes a subsystem for recording the movement of the cantilever to extract information from the electric and/or electromagnetic field. The system further includes a means of adjusting a stiffness of the cantilever to heterodyne tune an operating frequency of the system over a frequency range.

Nanomechanical near-field grating apparatus and acceleration sensor formed therefrom

Patent Carr, Dustin Wade [Albuquerque, NM]; Bogart, Gregory Robert [Corrales, NM]; Keeler, Bianca E. N. [Albuquerque, NM]

A nanomechanical near-field grating device is disclosed which includes two sub-gratings vertically spaced by a distance less than or equal to an operating wavelength. Each sub-grating includes a plurality of line-elements spaced apart by a distance less than or equal to the operating wavelength. A light source (e.g., a VCSEL or LED) can provide light at the operating wavelength for operation of the device. The device can operate as an active grating, with the intensity of a reflected or transmitted portion of the light varying as the relative positions of the sub-gratings are controlled by an actuator. The device canmore »« less

Narrow field electromagnetic sensor system and method

Patent McEwan, Thomas E [Livermore, CA]

A narrow field electromagnetic sensor system and method of sensing a characteristic of an object provide the capability to realize a characteristic of an object such as density, thickness, or presence, for any desired coordinate position on the object. One application is imaging. The sensor can also be used as an obstruction detector or an electronic trip wire with a narrow field without the disadvantages of impaired performance when exposed to dirt, snow, rain, or sunlight. The sensor employs a transmitter for transmitting a sequence of electromagnetic signals in response to a transmit timing signal, a receiver for sampling onlymore »« less

Mobile electric field sensor based phasor measurement unit for monitoring an electric power grid

Patent Liu, Yilu; Yao, Wenxuan; Zhan, Lingwei; ...

A system may include an electric field sensor, an analog to digital converter, and an estimator. The electric field sensor may measure electric fields of electric power grid. The analog to digital converter may generate digital output based upon measurements from the electric field sensor. The estimator may estimate phasor data of the electric power grid based upon the digital output.

Spatial feature tracking impedence sensor using multiple electric fields

Patent Novak, James L [Albuquerque, NM]

Linear and other features on a workpiece are tracked by measuring the fields generated between electrodes arrayed in pairs. One electrode in each pair operates as a transmitter and the other as a receiver, and both electrodes in a pair are arrayed on a carrier. By combining and subtracting fields between electrodes in one pair and between a transmitting electrode in one pair and a receiving electrode in another pair, information describing the location and orientation of the sensor relative to the workpiece in up to six degrees of freedom may be obtained. Typical applications will measure capacitance, but othermore »« less

Electric/magnetic field sensor

Patent Schill, Jr., Robert A.; Popek, Marc

A UNLV novel electric/magnetic dot sensor includes a loop of conductor having two ends to the loop, a first end and a second end; the first end of the conductor seamlessly secured to a first conductor within a first sheath; the second end of the conductor seamlessly secured to a second conductor within a second sheath; and the first sheath and the second sheath positioned adjacent each other. The UNLV novel sensor can be made by removing outer layers in a segment of coaxial cable, leaving a continuous link of essentially uncovered conductor between two coaxial cable legs.
