An integrated circuit includes a power grid having first, second, third, and fourth nodes for receiving first supply, first ground, second supply, and second ground voltage signals, respectively. Embodiments of the system and method may, when appropriate, inhibit use of stored IP addresses, for example by deleting or effectively deleting stored IP addresses. When reproducing the object signal, synthesizing a certain object signal, which is prohibited to reproduce by a reproduction protection information, is restricted by a reproduction protection controller, and then a video signal, which is permitted to reproduce is produced. The spline assembly has a first plurality of outer splines oriented in a first direction and a second plurality of outer splines oriented in a second direction different from the first direction. Body fluid flow through on of a body fluid flow circuit is controlled by alternating applying vacuum pressure and positive pressure to the circuit through a pumping chamber coordinated with flow control valves to effect a net downstream flow of body fluid through the circuit.
