The present subject matter relates to devices, systems, and methods for identifying the position of a movable component. A position sensor system is provided in which a Hall effect sensor is coupled to a fixed housing, and a plurality of magnets is coupled to a movable component that is movable to a sensing position at which the plurality of magnets is proximal to the Hall effect sensor. In this configuration, the plurality of magnets is arranged to produce an aggregate magnetic field having a flux concentration directed toward the Hall effect sensor when the plurality of magnets is in the sensing position.

A one-part adhesive including a grafted phenoxy resin, a polymaleimide compound, an organic carbonate, and an optional silane adhesion promoter is described. More particularly, the grafted phenoxy resin includes carboxylic acid and acrylate ester functionality. Methods of using adhesives to bond a thermoplastic urethane to a rigid substrate, e.g., in an injection or compression molding process, are also described.

An electric vehicle emulation system and method is provided using at least one force generator (FG) to induce a vibration emulating the feel of an internal combustion engine in an all-electric, hybrid-electric, or alternative fuel vehicle. The FG may be a circular FG (CFG), a linear FG (LFG), or a combination of both CFGs and LFGs.

A sensing system and method for detecting wear of an abradable layer on a stationary engine casing is provided. The system is capable of measuring the abradable thickness of the abradable layer by embedding abradable sensor in the abradable layer and measuring the changing electrical properties as the abradable sensor wears.

Compatibilizing agents for use in a wide variety of filled and unfilled liquid matrices and compositions comprising the agents are described. The compatibilizing agents can reduce the viscosity of the matrices and/or improve the stability of the matrices. Exemplary compatibilizing agents include one or more aryl sulfonyl derivatives, such as aryl sufonyl urethanes, aryl sulfonyl ureas, and aryl sulfonamides.

The present disclosure provides an improved circular force generator having a housing configured to reduce vibrational forces transmitted to an aircraft structure. Additionally, the disclosed configuration provide the necessary safety redundancies required by the aviation industry. The circular force generator includes mounting point around the exterior of the CFG housing and a central mounting point thereby providing redundant mounting points.

Systems and methods for measuring a clearance between a rotating machine component and a sensor unit are disclosed. In some aspects, a system includes a sensor unit oriented to detect the rotating machine component as the rotating machine component rotates past the sensor unit, the sensor unit including at least a first sensing element and a second sensing element spaced apart from the first sensing element. The system includes a sensor processing unit in electrical communication with the sensor unit. The sensor processing unit is configured for receiving a first waveform from the first sensing element; receiving a second waveform from the second sensing element; and determining, based on a comparison between the first waveform and the second waveform, a distance between the blade tip and the sensor unit.

A steer-by-wire device for controlling a vehicle includes a housing; an input shaft that is rotatable relative to the housing and is configured to receive a rotary input from an operator of the vehicle at a first end of the input shaft, the first end being located external to the housing; a rotor attached to the input shaft at a second, opposite, end of the input shaft, the second end being located internal to the housing; a sensor for detecting an angular position, an angular velocity, and/or an angular acceleration of the input shaft relative to the housing; and a coil for generating a magnetic field to generate a rotary force or torque in the rotor to resist rotation of the rotor. The rotor is attached to the input shaft to allow a relative movement between at least a portion of the rotor and the input shaft.

A method is disclosed to smooth the ride of a seat occupant by controlling the damping force of a fluid damper positioned between the seat and base. The method selects between different subprocesses to minimize the ride discomfort and to minimize peak seat accelerations and endstop jerks. The controller uses the input from the different subprocesses to create the best ride for the immediate operational conditions.

Torque sensing devices, systems, and methods are capable of measuring and/or determining a torque being transmitted through a shaft by measuring the torsional deformation of the shaft over a short length thereof. Such devices, systems, and devices have a sensor positioned adjacent to the outer surface of the shaft as it rotates, the sensor being positioned to maintain a substantially constant distance between the sensor and the outer surface of the shaft. The sensors may be variable reluctance (VR) sensors rigidly attached to a frame mounted on a bearing (e.g., a hanger bearing), which is mounted on the shaft, such that relative radial motion between the shaft and the VR sensor is minimized (e.g., so that they move in unison). Reducing this amount of motion results in a more accurate torque measurement.
