Abstract: A clutch assembly includes a rotatable input shaft, a clutch housing fixed relative to the input shaft, an input disk coupled to with the input shaft and rotatable therewith, and an output disk axially movable relative to the clutch housing to selectively engage the input disk. The clutch/brake assembly also includes an electrical generation system having a rotor shell coupled to the input shaft and rotatable therewith, a magnet coupled to the rotor shell, and a coil coupled to a coil support fixed relative to the rotor shell, wherein the coil is positioned with respect to the magnet to generate electrical current upon rotation of the rotor shell.

Abstract: An actuator assembly adapted to selectively cause an input disk of a clutch/brake assembly to engage an output disk of a clutch/brake assembly. The actuator assembly includes a movable piston integrated with the clutch/brake assembly. At least a portion of the clutch/brake assembly defines an expansible chamber in combination with the piston. The piston is movable in the clutch/brake assembly to selectively cause the input disk to engage the output disk. The actuator assembly also includes a housing positioned remotely from the clutch/brake assembly, and a fluid compressor located within the housing. The fluid compressor is operable to generate a fluid pressure and provide the fluid pressure to the expansible chamber to move the piston.

Abstract: An actuator device self-contained within a housing and adapted to move an object. The actuator device includes a movable piston positioned in a cylinder portion of the housing. The cylinder portion defines a longitudinal axis, whereby the piston is movable along the longitudinal axis in response to an accumulation of air pressure within the cylinder portion. The actuator device also includes a rod coupled to the piston for movement with the piston. The rod at least partially extends outside of the housing to couple to the object. Further, the actuator device includes an air compressor located within the housing. The air compressor transfers air from a location in the housing outside the cylinder portion to a location inside the cylinder portion.
