The present invention relates to an external rotor motor for a treadmill. Phase invertible compositions in accordance with the invention are prepared by combining a liquid proteinaceous substrate and a liquid crosslinking composition, where the liquid crosslinking composition includes a macromolecular crosslinking agent. The method further includes providing instructions, based upon the profile data and the vehicle data, to the user for addressing the condition. A present signal binary value determines which comparator is coupled to the receiver output, optionally by using exclusive-OR logic with SSVTR andSSVTR.
