A transmission capable of triple overdrive includes a main box section connected to a first input shaft. The outside electrodes are applied to the outside of the stack in the form of a coating of an elastic, electrically conductive polymer material. A frequency spectrum representing the ECG data is generated via a Fourier transform. An exhaust bypass valve cartridge includes a valve member removably disposed in the bore of the housing, and shaft structure associated with the valve member so that rotation of the shaft structure rotates the valve member. The present disclosure also provides a method of manufacturing such a brushless permanent magnet machine.
