A compressed gas regulator of a piston type is disclosed in which a regulator is configured with an input valve situated entirely inside a compressed air canister, which regulator is then attached to a paintball gun, marker or other device for providing discrete charges of gas at a predetermined pressure to the attached device. Mobile data processing Systems interact with each other as peers in communications and interoperability. The method and system include embedding at least one control structure in the complex data stream. When panels of the discontinuous outer layer are impacted by a foreign object, the force may be transferred to the flexible layer, rather than propagating through the outer layer. Various embodiments of the switchable charge acquisition circuits and corresponding charge integrator circuits provide lower power consumption, increased operational stability, substantially reduced integrated circuit area, and increased temperature stability. The prosthesis provides for both axial and radial compliance.
