This passive electrical circuit design allows division of voltage depending on the direction of current. The design consists of solid-state passive electrical components (resistors and diodes). The circuit allows serial actuation of smart-material transducers with unsymmetric actuation range. This circuit handles both without any physical changes by choosing ...

Decoding speed is a bottleneck for many sensors, especially for cases where real-time detection is preferred. Typically, lots of computation works are needed to process the collected date to get the desired measurant, and the speed is limited by the operation speed of the CPU or DSP chips. The ...

Decoding of an interferometer is related to the challenging sinusoidal frequency estimation problem. Due to the huge number of the local minimum, it is very hard to get an accurate estimation of the frequency from a sinusoidal signal, and hence the traditional decoding methods for interferometer are only able ...

The calibration system is designed to produce repeatable radiative heat fluxes at for calibrating heat flux gages. Although the system is specifically designed for high temperature sensors that are not actively cooled, it also provides a cheap and simple method for calibrating any sensors at reasonable steady-state heat flux ...

Because the invented sensors are immune to electromagnetic interference and can also resist the huge electric stress inside high voltage transformers, they can be installed much closer to the fault sources than current other systems do, which makes the analysis more accurate and prompt. Since the new sensors are ...
