Abstract: A system for providing operational access to equipment or vehicles is disclosed wherein digital access codes are assigned and transported over-the-air governing a vehicle's or equipment's use. The access codes can be generated in connection with comparison of entered and stored biometric data and/or entered code from a keypad. Various security protocols can be used to ensure the secure dispatch and delivery of code information.

Abstract: A wireless equipment management system is provided which automatically orders parts in connection with equipment maintenance schedules generated using sensors remotely located with the equipment. The system additionally uses diagnostic software to analyze fault conditions within the equipment using the sensors, and parts are automatically ordered in conjunction with equipment service needs as determined by the system.

Abstract: A by-pass oil refining device for an internal combustion engine is equipped with an atomizing nozzle that constricts oil flow from a solid contaminant filtering element to a vaporization chamber where liquid contaminants are vaporized. The atomizing nozzle has a constricting orifice which is of a diameter sufficiently large to allow recirculation of oil to the vehicle engine, but which is small enough so that oil emanating from the filtering element and entering the vaporization chamber is atomized into a mist. Atomization of the oil significantly increases the extent to which liquid contaminants are vaporized and removed.
