摘要： An induction device has an elongated core made of two or more uniform ferromagnetic spaced-apart toroids. A first winding around the core creates an inductor. When the induction device includes a second winding, a transformer is created. The transformer acts as a powercord transformer when the exposed ends of one winding are available at one end of the elongated core for connection to a source of alternating current and the exposed ends of the other winding are available at the other end of the core for connection to a load. An inductor with a single-turn winding can be constructed by first forming the core by stacking two or more ferromagnetic toroids end-to-end and spaced apart, then threading two wires through the core center and placing two wires outside the core and connecting the ends of the wires to create the winding. A transformer can be constructed by first following the steps to create an inductor. A second winding is then created in a similar manner as the first winding.

摘要： An improved dental procedure and apparatus where ultraviolet radiation pulses are used to etch selectively both hard tissue and soft tissue in dental procedures. There exists distinct ablation thresholds for hard and soft tissue which are dependent on the material being ablated for a given wavelength of the ultraviolet radiation. Sufficient differences in ablation threshold exist for enamel, dentin, and carious material, thereby allowing dentists to perform both hard tissue and soft tissue procedures without excess damage to healthy enamel, dentin or other pulp structures.
