摘要： An electromagnetic resonant sensor (800) has a dielectric sensor body (802) through which electromagnetic wave energy is propagated. The sensor body (802) has a cavity, with surfaces facing one another to define a gap (810) that varies as a function of a parameter to be measured. The resonant frequency of an electromagnetic standing wave (814) in the body (802) and the variable gap (810) changes as a function of the gap dimension.

摘要： A very high temperature microbeam sensor of a resonant integrated microstructure having an electrostatic beam driver and an optical fiber pick-up for sensed light from the beam. The high temperature sensor has no components that are vulnerable to temperatures up to 600 degrees C. Associated components for detection, processing and driving are remote from the sensor environment. By using different materials in the beam assembly, such as tungsten for the beam, and sapphire for the substrate and the shell, the sensor can withstand temperatures up to 1000 degrees C. Also, optical fiber may be used for long distance connections between processing electronics and the driver in the sensing device, by locating a photo detector just outside the very or ultra high temperature sensing environment, and then using optical fiber for sending long distance signals from the processor to the driver photo detector, for eliminating electrical signal-to-noise problems.

摘要： An optically driven, electromagnetically oscillating resonant sensor subjected to a stress force wherein the optical driving energy and the optically communicated signal generated in response to the stress force are both communicated a substantial distance along a single optical fiber (14). A portion of the supply energy (19) drives the oscillatory mechanism (20) and a portion is reflected to a frequency detector (18) by the shuttering action of the resonant element. The device may be configured so as to be electrically driven and optically sensed, optically driven and electrically sensed, or both optically driven and optically sensed for maximum retrofit versatility in past, present, and future process control systems.

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for testing an electromechanical systems (EMS) device. In one aspect, a laser is directed at a driven EMS device, and the reflected light pattern is analyzed to provide information regarding the characteristics of the driven EMS device. In some aspects, the reflected light pattern is analyzed to determine a resonant frequency of the EMS device or the damping forces acting on the EMS device. The resonant frequency can then be used to determine stresses within the EMS device, or pressure or temperature within a device package encapsulating the EMS device.

摘要： Measurement apparatus having a cantilever and a fluid flow channel, the cantilever being positioned in the channel so that it projects in a direction parallel to the direction of fluid flow. In an associated method, the cantilever is positioned in a fluid flow channel such that the cantilever extends parallel with the direction of fluid flow in the channel. Fluid is caused to flow in the channel at a known velocity. The resonant frequency of the cantilever is measured at one or more velocities of fluid flow and calculating the spring constant of the cantilever using the measured resonant frequency or frequencies. If the spring constant of the cantilever is known, the measurement of resonant frequency of the cantilever is used to determine the velocity of the fluid flow.
