The encoding method includes the step of performing conversion encoding in such a manner as to permit decoding of encoded words in units of a code word. Alternatively, one or more threaded drive rod offset from a longitudinal axis engages a worm gear or flex-neck articulation mechanism. Dependency links associated with events corresponding to the embedded elements are selected to describe the workflow of the components for operation when executed on the device.
