Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism’s reaction to the introduction of the medical device to the organism. A core liquid and a coating liquid are supplied to each of the nozzles from pumps through distributors. An application of the computing device is identified that corresponds to the recognized traffic pattern and responsive to this identification, at least a portion of the identified application is woken. The body portion has at least one substantially hollow interior section and at least one selectively openable door assembly for access into the substantially hollow interior section. Thus, it is possible to open and close the exhaust and intake valves with inherent opening and closing timings, while easily avoiding interferences among components. The reduced torque brake mode absorbs energy and reduces dynamic loading thereby.
