To efficiently personalize multiple bus interfaces, an inputoutput integrated circuit is provided. Arranged between the roller pairs is a squeeze-out surface with a wiper blade set against the squeeze-out surface. The nozzle comprises a fuel injection port oriented to direct a fuel spray against a surface of the sleeve An inlet in the sleeve allows air and fuel to enter the shielded space to form a combustible mixture therein. Currently used brake assemblies employing cylinder type actuators may be retrofitted with the brake actuator assembly of the invention. Furthermore, since the frame as well as the substrate may be flexible, multiple, flexible substrate assemblies may be stacked one on top of another wherein an upper assembly has a different radius than a lower module and any intermediate assemblies have progressively differing radii from bottom to top position. One or more mechanisms are incorporated into the random number generator to ensure that a random bit is not generated when a plurality of the core random elements generate a bit at the same time.
