Abstract: Embodiments of the present disclosure are directed towards rotary variable differential transducers. The transducer may include a housing and an armature shaft included within the housing. The transducer may further include an input shaft configured to mate with an airplane shaft. The input shaft may be located independently from the armature shaft.

Abstract: Disclosed are assemblies, systems, devices and methods, including an assembly to determine an angular position of a rotatable structure external to the assembly. The assembly includes a sensor including a rotatable member, a main winding set and at least one auxiliary winding, and also a coupling element to couple the sensor to the external rotatable structure to cause rotation of the rotatable member of the sensor in response to rotation of the external rotatable structure. Resultant voltages at the main winding set and at the at least one auxiliary winding are produced based, at least in part, on an angular position of the rotatable member of the sensor. The angular position of the external rotatable structure is determined based on the resultant voltages at the main winding set and at the at least one auxiliary winding.

Abstract: Disclosed are devices, systems, assemblies, couplers, and other implementations, including a coupler that includes a first coupling element matingly engaged to a second coupling element, each of the first and second coupling elements including a plate defining an opening, a projection extending from a first surface of the plate, and a socket extending from a second surface of the plate and configured to receive a rotatable member. The projection of the first coupling element is received in the opening of the plate of the second coupling element, and the projection of the second coupling element is received in the opening of the plate of the first coupling element. The matingly engaged coupling elements are configured to rotate in response to rotation of a first rotatable member of a first device received in the socket of the first coupling element.

Abstract: An angular displacement sensor. The input shaft is supported by a housing and fixed to a main gear. A plurality of secondary gears are arranged around and meshed with the primary gear. A plurality of displacement sensors are integrally coupled with the secondary gears. Advantageously, the main shaft is formed with a shear notch. Further, each of the secondary gears are coupled to the displacement sensors so as to break free in case of a jam.
