Abstract: A harmonic drive, having: a housing; an output shaft within the housing; an input shaft within the housing, the input shaft is configured for being in a first position in which rotation of the input shaft rotates the output shaft, and a second position that is axially offset from the first position, in which rotation of the input shaft does not rotate the output shaft; a solenoid coil within the housing that, when energized, moves the input shaft to the second position; and a spring within the housing that, when the solenoid coil is not energized, moves the input shaft to the first position.

Abstract: Assemblies having a first structure, a second structure movable relative to the first structure, and an actuator system arranged therebetween and configured to control relative movement therebetween. The actuator system includes a drive shaft, a first element configured to be driven in a first direction, and a second element configured to be driven in a second direction. A spar is fixedly connected to the first structure and a spar connection pivotably connects the first element to the spar at a fixed coupler. The drive shaft, the first element, and the second element are housed within the second structure. Rotation of the second element causes a translation motion of the drive shaft away from the first structure and rotation of the first element about the fixed coupler such that the second structure is translated and rotated relative to the first structure.

Abstract: An electromechanical rotary actuator includes a drive member, a motor disposed inside and directly coupled to the drive member, and an output arm. The motor has a rotor configured toward an outside of the motor and directly coupled to an input of the drive member and a stator configured toward an inside of the motor and positioned inside the rotor. The output arm is disposed about the motor and is drivably connected to the drive member. The output arm defines an arcuate opening.

Abstract: A method for reducing condensation includes moving a linear motor slider that is positioned within a housing of an actuator. A first gas is pushed out of a transfer plate chamber through a first vent. A second gas is drawn into the transfer plate chamber through a second vent. Moisture is removed from the second gas as the second gas is being drawn into the transfer chamber by passing the second gas through at least one of a hydrophobic or oleophobic material.

Abstract: An electromechanical actuator includes a ground arm, an output arm rotatable about an axis of rotation relative to the ground arm and a position sensing arrangement to determine an angular position of the output arm relative to the ground arm. The position sensing arrangement includes a position sensor fixed at the ground arm. The position sensor is configured to sense magnetic reluctance. A sensed portion is located at the output arm proximate to the position sensor. The sensed portion includes a geometric variation in an output arm surface configured to vary a magnetic reluctance sensed at the position sensor as a function of angular position of the output arm relative to the ground arm.
