Abstract: An improved selective power assist device includes a controller for controlling a motor selectively coupled to the door and a clutch interposed between a drive shaft and a motor shaft, each having an angular velocity, whereby the motor is operatively coupled with and decoupled from the door. A brake assembly is disposed to synchronize the angular velocities of the drive shaft and the motor shaft allowing the clutch to operatively couple the motor with the door.
