Abstract: A sensor system includes a rotor antenna, a radio frequency (RF) sensor, a stator antenna, and one or more frequency selective structures. The rotor antenna and the RF sensor are disposed on an outer surface of a shaft and are conductively connected to each other. The RF sensor generates measurement signals as the shaft rotates. The stator antenna is mounted separate from the shaft and positioned radially outward from the rotor antenna. The stator antenna wirelessly receives the measurement signals from the rotor antenna across an air gap. The one or more frequency selective structures are disposed on the outer surface of the shaft and configured to dissipate electromagnetic current that is conducted along the shaft to alleviate interference of the measurement signals.

Abstract: An RF transmission system includes an RF source that provides an RF input and one or more RF MEMS transmission devices coupled to the RF source to receive the RF input therefrom and generate output signals for transmission to an RF load. Each of the RF MEMS transmission devices comprises a substrate, a conducting line formed on the substrate to provide signal transmission paths between a signal input of the RF MEMS transmission device and a signal output of the RF MEMS transmission device, and a plurality of switching elements positioned along the conducting line and selectively controllable to define the signal transmission paths between the signal input and the signal output. Each of the RF source and the RF load has a first characteristic impedance and the one or more RF MEMS transmission devices have a second characteristic impedance that is greater than the first characteristic impedance.

Abstract: A rotary machine includes a rotatable shaft and a retaining ring coupled to, and at least partially extending about, the rotatable shaft. The rotatable shaft defines a longitudinal axis. The rotatable shaft and the retaining ring define an annular cavity. The rotatable shaft and the retaining ring each include a radially outer surface. The rotary machine also includes a monitoring system including a stationary reader-antenna positioned proximate the retaining ring and a radio frequency (RF) coupler. The RF coupler includes at least one flexible antenna band coupled to, and extending over, the radially outer surface of the retaining ring. The flexible antenna band is configured to establish RF coupling with the stationary reader-antenna. A sensor die is coupled to the flexible antenna band. The sensor die extends into the substantially annular cavity and the sensor die is also coupled to the radially outer surface of the rotatable shaft.
