Abstract: A sensor assembly that includes a surface acoustic wave (SAW) sensor. The SAW sensor is adapted to measure a first environmental condition in response to receiving an RF signal. The SAW sensor includes a substrate having a layer of piezoelectric material. The SAW sensor further includes a interdigitated transducer (IDT) formed on the piezoelectric material. The IDT includes two comb-shaped electrodes having interlocking conducting digits in a first arrangement. The interlocking conducting digits in the first arrangement generates a first signal modulation of an RF signal received by the first IDT. The first signal modulation identifies the first SAW sensor.

Abstract: A rapid pressure rise detection and management system that detects internal pressure changes in a transformer. The rapid pressure rise detection and management system communicates with one or more pressure sensors attached to a tank of the transformer and measures the rate of pressure change versus time. The rapid pressure rise detection and management system then compares this rate of pressure change against a set of parameters to determine if this pressure change is an internal fault requiring the transformer to be taken offline or external fault to be ignored. This rapid pressure rise detection and management system may be a standalone device or work with other monitoring/controlling equipment to expand its sensing and management capabilities.

Abstract: The state of a flame in a gas turbine combustor is acoustically monitored using a single dynamic pressure sensor within the combustor. A dynamic pressure sensor output signal is received from the single sensor and is processed to determine a flame status. The signal is processed by performing an autocorrelation operation to identify time-separated portions of the signal and to determine that the time-separated portions of the signal include portions indicative of acoustic oscillations emitted by the flame in the gas turbine engine combustor and received directly by the single acoustic sensor, and portions indicative of reflections.

Abstract: A cylindrical quartz crystal transducer that exhibits a low probability of twinning, and uses a combination of resonator signal inputs at the B-mode and C-mode frequencies to calculate resonator temperature. Crystallographic orientations are disclosed where combinations of B-mode and C-mode resonant frequencies exist that are sufficiently independent of pressure to enable accurate calculation of temperature under transient conditions. Such a transducer is usable at higher pressures and temperatures than conventional quartz pressure transducers. Furthermore, because the structure allows a choice of crystallographic orientation, other characteristics of the transducer, such as increased pressure sensitivity and activity dip-free operation, may be optimized by varying crystallographic orientation.
