Abstract: Fuel combustion and waste conversion can be achieved by passing an axial vortex stream in a combustion chamber in a first linear direction, and passing a peripheral vortex stream as a counterflow to the axial vortex stream in a direction generally opposing the first linear direction. The peripheral and axial vortex streams can be merged so that a first fuel and oxidant in the streams at least partially combust to form a product stream, the product stream moving in the first linear direction to an outlet at the second end of the combustion chamber. Vortices can be generated by tangentially introducing fluid streams into the one or more chambers. A primary chamber, a main chamber, and an afterburner chamber can be connected in series. Second fuel and pre-chambers can be used to stabilize and enhance combustion. Reagents can be introduced to refine gaseous streams including pollutants.

Abstract: Novel apparatus for treating a disorder of a biological tissue in a mammal by stimulating the biological tissue with light having selected optical parameters. The apparatus has a power source, a central microprocessor with stored optical parameter protocols and wireless probes to receive the protocols and to generate and transmit the light. The invention also relates to a method for stimulating healing of a disorder of a biological tissue in a mammal by stimulating the biological tissue with light having selected optical parameters.

Abstract: A circuit for electrotherapy and electronic acupuncture, in which a pulse train is produced having negative pulses of a repetition rate of between 100 and 500 Hz, arranged in groups having a repetition rate of between 1 and 50 Hz. A positive bias is provided so that the integral of the pulse train signal is zero. The signal is randomly switched sequentially from one skin stimulus site to another with application times which can be adjusted between about 1 and 20 seconds (or more), to reduce or prevent brain habituation. Optionally there is a rest period between applications of the signal, in which no signal is applied to the skin sites.
