Abstract: A joint assembly couples a linear actuator to a body. The joint assembly includes a first body having a first surface and a second body having a second surface. The first body is coupled with the second body. The first surface and the second surface have arcuate configurations that are complementary to facilitate rotation of the first body relative to the second body about a first axis, a second axis, orthogonal to the first axis, and a third axis, orthogonal to both the first axis and the second axis. The joint assembly also includes a damper disposed between the first body and the second body and configured to dampen translational motion of the first body toward the second body in response to movement of the linear actuator relative to the body.

Abstract: A ball screw spline actuator includes a shaft, a ball nut, and a ball spline. The shaft includes a helical groove and a spline groove intersecting the helical groove forming intersections having a least one ridge including a first surface finish formed by a first manufacturing operation. The ridge is subsequently reformed through a second manufacturing operation to include a second surface finish to reduce stress concentrations in the ridge from cyclical loading from at least one of the ball nut or the ball spline. In one example, the second manufacturing operation reforms the ridge to include a surface finished edge.

Abstract: A suspension system includes a primary actuator, an inertial actuator, and a controller. The primary actuator applies force between a sprung mass and an unsprung mass of a vehicle to control movement therebetween. The inertial actuator applies force between the unsprung mass and a reaction mass to damp movement of the unsprung mass. The inertial actuator has a threshold capacity. The controller controls the primary actuator and the inertial actuator. The controller determines a required damping of the movement of the unsprung mass, and apportions the required damping between the primary actuator and the inertial actuator.

Abstract: Described here are devices for intranasally delivering therapeutic gases to a patient. The devices may include a measurement chamber, a combination of pressure regulators and a sequencing mechanism that controls valves associated with the pressure regulators. When implemented in a hand-held dispenser, the hand-held dispenser may reliably deliver consistent doses of gas regardless of the unknown state and pressure of the therapeutic gas in the measurement chamber.
