An electrical machine capable of generating complex and compounded electrical signals, which may be applied to the human body for the purpose of effecting therapeutic, remedial and/or curative results, but which is rendered incapable of administering such signals at levels which might cause damage or other harm, by essentially containing a proportion of signals which, at high levels, will inflict unendurable discomfort. Such inclusions being unavoidably present at relative levels safely above those which might present the risk of unacceptable consequences. |
