Abstract: A procedure electrically stimulates a nerve or group of nerves. Unlike conventional systems this procedure is tuned to target a large or small group of neurons using noninvasive electromagnetic induction. This system is capable of doing this by using the principles of the alternating current in a capacitance inductance series resonance circuit. In this system the nerve resonator treats the neuron like a thin conductor placed between the plates of a capacitor in series with an inductor and then tuned to resonate with the appropriate frequency of alternating current. The system could also be inductance tuned for a given frequency. Once the system is tuned, the current amplitude in the entire circuit including the thin conductor or nerve fiber can be externally controlled.

Abstract: A medical tool such as a prophy angle is provided having primarily plastic parts to make disposing more economical. A portion of the drive shaft is made of metal to eliminate detrimental deformation. The housing is made of two plastic halves which snap-fit together and have projecting portions which surround a pair of oversized plastic beveled gears. A prophy cup having a locking projection is provided so that the locking projection fits into locking cavity on a stud of the tool. Vanes are disposed on the inside of the cup and have a step-like configuration to aid in retaining polishing paste in the cup.
