A method for designing a drill bit that has at least one roller cone and a plurality of cutting elements, including selecting initial bit design parameters. A set of fixed codes is captured from a rolling code transmitter that is used to actuate a corresponding rolling code receiver. At least one sealing bead is provided in the gasket plate, which surrounds at least one fluid opening of the gasket in a closed manner and is elastically deformable in its height. A first circuit selectively couples the first and second multi-bit registers to the output pad.
