20100234753 | Apparatus for determining health of an individual - A method and apparatus for obtaining data relevant to the state of health of an individual by measuring the signal spectra at various points on the individual's body. Illustratively, the measurements are at points on the individual's hand, implemented with a glove that includes numerous electrical point contacts. | 09-16-2010 |
20120209136 | Method and Apparatus for Determining and Improving Health of an Individual - A method and apparatus for obtaining data relevant to the state of health of an individual by measuring the signal spectra at various Jing Luo network termination points on the individual's body. Illustratively, the measurements are at points on the individual's hand, implemented with a glove that includes numerous electrical point contacts. A healing session ameliorates a malady by identifying the signature of the malady as reflected in a chosen subset of termination point, determining the amount of energy that is necessary to null out the malady's signature, and applying the determined energy to one or more termination points. | 08-16-2012 |
