Abstract: A sensor system for monitoring a condition of a piston rod includes an interrogator system having a first coil winding coupled to a housing and radially spaced from the piston rod such that a gap is defined between the first coil winding and the piston rod. A second coil winding is coupled to the piston rod and is inductively coupled to the first coil winding. The second coil winding is configured to communicate with the first coil winding through a range of linear movement of the piston rod relative to the housing. A sensor is coupled to the second coil winding. The sensor is configured to measure a characteristic associated with the piston rod and generate a current in the second coil winding to transmit, via the inductive coupling with the first coil winding, an electrical output signal associated with the characteristic to the interrogator system.

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 radio frequency (RF) die package includes a switch assembly comprising an RF transmission line and a plurality of conductive mounting pads formed on a first substrate. A switching mechanism selectively couples a first portion of the RF transmission line to a second portion of the RF transmission line. An inverted ground plane assembly is coupled to the plurality of conductive mounting pads such that an electromagnetic field generated between the RF transmission line and the inverted ground plane assembly does not permeate the first substrate in a region of the switch assembly proximate the switching mechanism.

Abstract: A method for providing overspeed protection for a gas turbine engine having an engine shaft includes monitoring, via an overspeed protection system, a torque of the engine shaft. The method also includes determining, via the overspeed protection system, at least one additional condition of the engine shaft. Further, the method includes determining, via the overspeed protection system, an overspeed condition of the gas turbine engine when the torque of the engine shaft drops below a torque threshold and the at least one additional condition of the engine shaft is indicative of the gas turbine engine being in an operational state. Thus, the overspeed condition is indicative of an above normal rotational speed of the engine shaft. In addition, the method includes initiating a shutdown procedure for the gas turbine engine in response to the determined overspeed condition to reduce the rotational speed of the engine shaft.
