Abstract: A gearbox is described that includes a magnetic gear irrotationally mounted on one shaft and a set of gears on another shaft, wherein the one gear is in sequential magnetic interaction with the set of gears to alter to rotational speed of either the one gear or the set of gears.

Abstract: A magnetic gear system including magnetic gearboxes where one of a driving gear and a driven gear are in sequential magnetic linkage, and one of the magnetic gears can be tilted relative to the other gear wherein the magnetic gears are prevented from overlapping each other to prevent loss of sequential magnetic interaction. A magnetic gearbox is also disclosed where a driving gear can be tilted relative to a driven gear to change the torque, the rotational speed of the driven gear, and if tilted far enough, to change the direction of rotation of the driven gear. Another magnetic gearbox includes a pair of magnetic gears that can be manipulated to result in a reversal of direction of rotation of a driven gear from a driving gear without changing the magnetic properties of either gear.

Abstract: The present invention is an apparatus and method for quantifying an individual's level of impairment, whether due to infirmity, substance use or mental state. This is performed through a test which measures a test subject ability to perform hand-eye activity tasks over a period of time and relating those results to a blood alcohol content equivalence table. The results of the test, along with the test subject's identifying data are then secured and uploaded to a secure database.

Abstract: An apparatus having at least one rotatable driven object having an edge on which are disposed a series of adjacent magnets of alternating polarity and a driving object rotatable by an external motor torque and having a series of adjacent magnets of alternating polarity on a magnet supporting surface. The magnet supporting surface of the driving object is rotatable through a common region approximately centered about the point of closest approach to the magnet supporting edge of the driven object for sequentially placing magnets of the driving object in the region enveloping the effective interactive range between the two objects. The fields of magnets of opposite polarity of the driving object interact with the fields of the magnets on the driving object to effect rotation of the driven object. Disclosed are structures for torque limiting wheels, magnetic gear trains, reduction gears and ball joints, and propulsion systems for watercraft and aircraft.

Abstract: An apparatus having a driving magnetic gear and a driver magnetic gear, disposed on each of which are a series of adjacent magnets of alternating polarity. The magnetic gears are tiltable relative to each other, and the angle of the imaginary driver gear plane at the pivot point between the driving gear and the driver gear must be less than 90° to prevent loss of sequential magnetic interaction beyond which angle, reversal of rotation relative to the driver gear would occur when the sequential magnetic interaction is re-established.

Abstract: The safety barrier comprises a longitudinally extending rail rigidly engaged by support means disposed at intervals along the rail. A cable under tension is disposed proximate the rail and extends therealong so that the rail and cable combine to prevent failure of the barrier upon being impacted. In a preferred embodiment, the rail is cylindrical, the cable is disposed within the rail, and the cable is supported within the rail by a holding means such as grout. The barrier is constructed so that the grout may be inserted into the rail after the cable is in place and under tension. Moreover, in order to facilitate easy replacement of a damaged section, the rail may be removed from about the cable without replacing the cable and the cable is sheathed so that a damaged cable may be replaced without disassembly of the entire barrier.
