Methods for providing an enhanced scheduling process are discussed. An inflation assembly includes an inflatable bladder within the tunnel, a tube having an intermediate extent extending through the aperture and having a lower end coupled to the bladder and having an upper end positionable in the mouth of a wearer for inflation. According to some embodiments, the panels include an outer wall and an inner wall defining an inner space therebetween in which is situated a heat exchanger and a temperature sensor. A clutch actuator includes a motor-generator that has a rotor rotatably drivable by one of the first rotatable member and the second rotatable member, and has a stator powerable to rotatably drive the rotor relative to said one of the first rotatable member and the second rotatable member. When the COM object is thread-safe, the system instantiates the COM object from the current thread and stores an indication in the wrapper object that the COM object can be accessed from any thread.
