Charles J. Crosby, DO, MD (H), founded Crosby Advanced Medical Systems, Inc. to offer medical practitioners and patients safe, effective, quantum-physics-based devices to relieve pain. In 1997, Dr. Crosby attended the last lecture by the late osteopathic physician, Robert C. Fulford, DO, author of Dr. Fulford’s Touch of Life: The Healing Power of the Natural Life Force. Dr. Fulford stated that quartz crystals would be the basis of medical treatments in the 21st century. He then demonstrated how to program and use quartz crystals for medical purposes. Inspired by Dr. Fulford, Dr. Crosby went on to link quartz crystal technology with a TENS (Transcutaneous Electrical Nerve Stimulator)—thus creating the first CAMS unit the TensCam Classic in 1998, and since replaced by the TensCam/RJV Jr. CAMS uses electromagnetic energy to re-establish the healthy resonant frequency of 7.86 vibrations per second in dysfunctional areas of the body. Result: normal functioning is restored without chemical or mechanical intervention.
