A system and methods for transferring information between two or more incompatible security domains or levels of classification by embedding policy-centric content management components into an information-centric network. Core materials such as a soft magnetically permeable medium that is amenable to formation of a variety of particularized shapes. An actuating shaft may be connected to the control lever in a rotationally fixed manner along a rotation axis. On the contrary, if an expression, encoding date\u2267invalidation date, the encoded content is determined to be illegal content. In one feature, third and fourth signals derived from the first and second signals are used to eliminate balance point ambiguity which is present using the first and second signals alone. In one illustrative embodiment, a position sensor is used to sense the current position of the actuated part.
