20220134122 | Method of Treatment Using Nuclear Magnetic Photon Excitation - This invention is a method of treatment for inhibiting the cells of an infection from performing synthesis, while allowing the immune system within the infected host to maintain cell proliferation. This is accomplished by infusing an element isotope into the blood stream of the infected host. The element isotope must be capable of attaching or binding to the site of DNA or RNA polymerase. Thus, when a magnetic field and targeted low energy electromagnetic radiation are applied to substantially the location of the infection, the cells of the infection are inhibited from replicating. Therefore, the cells of the infection are prevented from replicating, which allows the host's immune system to more efficiently destroy the infectious cells through the natural process of producing antibodies. | 2022-05-05 |
20220134123 | MAGNETIC STIMULATION APPARATUS, METHOD, AND SYSTEM - An apparatus and method configured to generate a magnetic field applied to a target location. The apparatus and method include a magnetic stimulation apparatus, including a permanent magnet configured to generate a magnetic field, and a magnetic shield configured to shield at least one target region from the magnetic field generated by the permanent magnet, wherein the magnetic shield includes at least one gap region configured to expose at least one other target region to the magnetic field generated by the permanent magnet. At least one gap region is moveable so that the shielded at least one target region is exposed to the magnetic field at the other target region. | 2022-05-05 |
