The sensor system further includes a second antenna separated from the first antenna by an air gap distance. The second antenna is configured to be coupled to the piston rod of the reciprocating system. The second antenna is a patch antenna and is configured to communicate with the first antenna through a range of translational movement relative to the first antenna. The sensor system further includes a radio frequency sensor coupled to the second antenna. The radio frequency sensor is configured to be coupled to the piston rod of the reciprocating system, measure a characteristic associated with the piston rod of the reciprocating system, and transmit data associated with the characteristic to the first antenna of the interrogator system through the second antenna.

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: The present disclosure is generally related to a fault isolation sensor system for use with determining whether a potential fault is more likely to be on a rotor side or a stator side. The measurement signals are transmitted from the rotor antenna to the stator antenna, and then from the stator antenna to a controller. The controller is configured to monitor the measurement signals. If the measurement signal is outside of a predetermined range or past a predetermined threshold, then the stator antenna can be interrogated with an interrogation signal with a reflected signal being compared with the interrogation signal and a ratio thereof being used to identify the potential side of the fault.

A first capacitor plate of a first capacitor is formed on an interior surface of a cap. A second capacitor plate of the first capacitor is formed on an exterior surface of the cap. The first capacitor plate of the first capacitor overlays and is spaced apart from the second capacitor plate of the first capacitor along a direction that is orthogonal to the exterior surface of the cap to form the first capacitor. The cap is coupled with the first surface of the active feature layer such that the second capacitor plate of the first capacitor is in electrical communication with at least a first active feature of the active feature layer.

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.
