Abstract:
1. An apparatus for generating an electrical signal for use in biomedical applications said apparatus comprising (a) a first frequency generator that generates a first intermediate output, said first intermediate output being coupled to and thereby controlling (b) a second frequency generator that generates one or more second intermediate outputs, said second intermediate outputs being coupled to (c) one or more active or passive electrical components that modify said second intermediate outputs thereby producing one or more third intermediate outputs, said third intermediate outputs being coupled to and thereby controlling one or more logic-level drivers that generate one or more fourth intermediate outputs, said fourth intermediate outputs being coupled to an output filter that generates a final output, said final output constituting said electrical signal comprising: (i) at least four relatively longer primary timing intervals T wherein the selection of said primary and secondary timing intervals, and of said voltage or current levels within each, cause said electrical signal to emulate a specific, defined mathematical function having an amplitude which varies with time, and wherein said biomedical application comprises pain relief, stimulation of tissue growth, acceleration of tissue healing, stimulation of bone growth, acceleration of bone healing, improvement of bone healing, improvement of bone density, reduction of tissue inflammation, repair of tissue damage, reduction of tissue swelling, promotion of tissue graft survival, promotion of tissue graft survival, modification of blood flow, enhancement of biochemical production, enhancement of tissue biochemical production, devitalization of organisms, enhancement of joint repair, enhancement of joint replacement, enhancement of blood storage, and improvement of neurological conditions.
