Improved actuators and valve control systems, and methods for controlling actuators andor engine valves, are disclosed. The invention further refers to dynamic logic cascade circuits comprising such a dynamic logic gate. Translucent indicator structures in the cover member define respective indicator shapes to allow backlighting to pass through the cover member. Folding the bus bars forms U-bend portions to contact with outer side surfaces of the ribs. The method can further route the call to the call destination when the caller is in compliance.
