Abstract: Electromechanical systems using magnetic fields to induce eddy currents and generate lift and thrust are described. A circumferential array of magnet elements which can be employed in the systems are illustrate. when the circumferential array rotates round its axis, it generates a travelling magnetic field moving along its axis. The travelling magnetic field over a conductive substrate induces eddy currents in the conductive substrate, the eddy currents provide an opposing magnetic field to generate magnetic lift and thrust to support and drive the circumferential array.

Abstract: One embodiment is a method including a unique soot loading metric. The method includes treating exhaust with a soot filter, sensing information including a pressure differential of the soot filter, a temperature of the soot filter, an ambient pressure, an air flow, and a fuel flow, evaluating the information to determine a value, and commanding a regeneration of the soot filter based upon the evaluating. The evaluating the information to determine the value accounts for a first contribution to the pressure differential attributable to laminar flow wall friction and a second contribution to the pressure differential attributable to turbulent flow. Another embodiment is a system including a unique soot loading metric.

Abstract: A new style trim knife comprising a handle, a head on a first end of said handle and a blade. Components are for securing the blade to the head. A hand of a person can grasp the handle to allow the blade to cut off protrusions and rises left by a molding process on plastic, rubber and any other molded product at a work area. A facility is built into the head for removing by a suction action the loose cutoff protrusions and rises with a vacuum unit. The loose cutoff protrusions and rises will not cause damage to equipment located at the work area.
