Abstract

A sensor apparatus and method for detecting an environmental factor is shown that includes an acoustic device that has a characteristic resonant vibrational frequency and mode pattern when exposed to a source of acoustic energy and, futher, when exposed to an environmental factor, produces a different resonant vibrational frequency and/or mode pattern when exposed to the same source of acoustic energy.

Apparatus and method for determining microscale interactions based on compressive sensors such as crystal structures

Patent McAdams, Harley; AlQuraishi, Mohammed

Techniques for determining values for a metric of microscale interactions include determining a mesoscale metric for a plurality of mesoscale interaction types, wherein a value of the mesoscale metric for each mesoscale interaction type is based on a corresponding function of values of the microscale metric for the plurality of the microscale interaction types. A plurality of observations that indicate the values of the mesoscale metric are determined for the plurality of mesoscale interaction types. Values of the microscale metric are determined for the plurality of microscale interaction types based on the plurality of observations and the corresponding functions andmore » compressed sensing. « less

Apparatus and method for detecting electromagnetic radiation using electron photoemission in a micromechanical sensor

Patent Datskos, Panagiotis G [Knoxville, TN]; Rajic, Slobodan [Knoxville, TN]; Datskou, Irene C [Knoxville, TN]; ...

A micromechanical sensor and method for detecting electromagnetic radiation involve producing photoelectrons from a metal surface in contact with a semiconductor. The photoelectrons are extracted into the semiconductor, which causes photo-induced bending. The resulting bending is measured, and a signal corresponding to the measured bending is generated and processed. A plurality of individual micromechanical sensors can be arranged in a two-dimensional matrix for imaging applications.

Sensor apparatus using an electrochemical cell

Patent Thakur, Mrinal [1309 Gatewood Dr., Apt. 1703, Auburn, AL 36830]

A novel technology for sensing mechanical quantities such as force, stress, strain, pressure and acceleration has been invented. This technology is based on a change in the electrochemically generated voltage (electromotive force) with application of force, stress, strain, pressure or acceleration. The change in the voltage is due to a change in the internal resistance of the electrochemical cell with a change in the relative position or orientation of the electrodes (anode and cathode) in the cell. The signal to be detected (e.g. force, stress, strain, pressure or acceleration) is applied to one of the electrodes to cause a changemore » « less

Well casing-based geophysical sensor apparatus, system and method

Patent Daily, William D [Livermore, CA]

A geophysical sensor apparatus, system, and method for use in, for example, oil well operations, and in particular using a network of sensors emplaced along and outside oil well casings to monitor critical parameters in an oil reservoir and provide geophysical data remote from the wells. Centralizers are affixed to the well casings and the sensors are located in the protective spheres afforded by the centralizers to keep from being damaged during casing emplacement. In this manner, geophysical data may be detected of a sub-surface volume, e.g. an oil reservoir, and transmitted for analysis. Preferably, data from multiple sensor types,more » « less

Housing apparatus for sensitive gas sensor

Patent Martin, Yves; Green, William; Van Kessel, Theodore G.

A sensor housing apparatus includes a housing having an enclosure and outer assembly, at least one flow path extending through the housing, a gas sensor disposed in the enclosure and a thermal mass. The thermal mass is mounted within the enclosure in thermal communication with the gas sensor, and is configured to transfer thermal energy from the gas sensor to an ambient environment surrounding the housing and minimize temperature gradients adjacent the gas sensor.
