Abstract: One aspect is an actuator system having a rotatable drive shaft and a parallel axis friction brake engaged with the drive shaft and configured to provide a drag force on the rotatable drive shaft. The parallel axis friction brake further includes a brake housing and a friction assembly that has at least one parallel axis shaft and at least one clip pressed over the at least one parallel shaft in an interference fit. The friction assembly is engaged with the drive shaft and coupled to the brake housing, at least a portion of the friction assembly rotating with the rotatable drive shaft to create the drag force.

Abstract: One aspect is a multi-axis clip hinge with a rotatable member having a spherical portion with a greatest outer diameter and a coupling portion for articulating said member. A clip is provided having an arm defining an inside diameter and comprising a connecting portion. The inside diameter of the arm is less than the greatest outer diameter of the spherical portion of the rotatable member and is engaged therewith such that it interferes with and grips the outside diameter of the spherical portion. A housing is configured to engage the connection portion of the clip thereby securing the clip to the housing. At least one of the clip and the housing prevents relative translational movement of the clip relative to the spherical portion yet allows the spherical portion to rotate in three axes of rotation relative to the clip.

Abstract: A roller lock device has a shaft and a housing configured over the shaft for selective relative movement thereto. A plurality of rollers is configured between the housing and the shaft, at least some of which are substantially conically shaped. A cage is configured between the housing and the shaft and adjacent the rollers such that the rollers are at least partially constrained from movement by the cage. A control is configured to move the rollers axially thereby engaging and disengaging the roller lock. The housing has ramps configured to receive the rollers, the ramps having a curved contour.
