Embedded systems include a variety of applications which not only safety-critical applications such as automotive devices and controls, railways, aircraft, aerospace and medical devices but also communications, ‘mobile worlds’ and ‘e-worlds’, the ‘smart’ home, clothes, factories etc. These terms describe the essential characteristics of electrotherapy devices used in medicine today. Furthermore, because all living matter emits some level of radiation via our endogenous EMFs, this might help explain the positive effects of many forms of therapies from positive imagery and biofeedback to acupuncture and polarity work. Many heart patients die due to cardiac arrest which occurs without any warning. 16. The Canadian government seems to agree and has said it sees no clear link between common electromagnetic exposure levels and any morbidity.13 Nevertheless, some research does in fact link EMF exposures to a number of health effects, including neurodegenerative disorders (amyotrophic lateral sclerosis), leukemia, miscarriage, and clinical depression. The idea that all living tissue is in motion, resonating in alternating fields (ELF EMF), is fundamental to the biologic electromagnetic paradigm. Physically nonthermal refers to being below the thermal noise limit at physiologic temperatures.2 The energy level at thermal noise is much lower than that required to cause heating of tissue, so any physically nonthermal application is automatically biologically nonthermal. Marino A, Becker RO. He went on to explain that this might be the reason why patients with brittle diabetes have such a hard time regulating blood sugar levels. Physical corrections aside, there is a growing body of evidence suggesting that psychological “auto correction” is possible, meaning that we are capable of self-regulating and correcting our individual electromagnetic profile. 1969;93(4):484-504. These MFs are produced by electric currents and specifically as a result of electron movement in 1 (DC) or 2 (AC) directions.

With the decrement in size and increment in processing power, small devices with the embedded system are capable of collecting patient data and making control decisions that may help in providing patients with better treatments and medications. Athenstaedt H. Permanent electric polarization and pyroelectric behavior of the vertebrate skeleton III: The axial skeleton of man. Z Zellforsch Mikrosk Anat. So an embedded system was introduced into some medical devices which are used to detect cardiac abnormalities which include, the irregularity of heartbeat and are diagnosed before the contingency of the heart attack in order to avoid the deadly cardiac arrest to a major extent. The Figure depicts how the electromagnetic spectrum and visible light forms a small portion of the total spectrum. Feychting M, Jonsson F, Pedersen NL, Ahlbom A. Medical Biophysics. These exogenous fields can be further subdivided into natural fields (earths geomagnetic field) versus artificial or man-made fields, such as transformers, electricity lines, medical devices, appliances, and radio transmitters. Such users are less likely to develop health problems in the future. The biophysical effects by which EMFs might act on bio-molecules are far too complex for this report. It is important to note that electro-magnetic energy often is used to assess or aid in the diagnostic process when used in electromyography, biofeedback, electroencephalography, electro-retinography, and in imaging tests such as magnetic resonance, positron emission tomography, computed tomography (CT), ultrasound, and radiography applications. Electromagn Biol Med. One such product which has taken the fitness world by storm is FitBit. Havas refers to EMF-susceptible hyperglycemic individuals as type 3 diabetics. New York: Morrow, 1985. NIH Report. Health Canada website. 2003;60(5):343-347. Our observation in astronauts (nongravity-induced osteopenia) is consistent with these findings. Geomagnetic cyclotron resonance in living cells. Subsurface defects cause abnormal thermal patterns, which indicate the presence of those defects. In IRT, thermal patterns on the surface of the test objects are monitored. San Francisco, CA: San Francisco Press, Inc.: 1991. Another important distinction we should make is that of endogenous fields (produced in the body) versus exogenous fields (produced outside of the body). It can be worn on hand as a bracelet and it tracks all our health measures such as blood pressure, weight, sleep etc, and help us reach our health and fitness goals. The basics of IRT, essential theoretical background, the procedures adopted for various measurements and applications of IRT in various medical fields are discussed in this review. In the field of NDT, the application of IRT is mainly in surface and sub-surface defect detection and online monitoring of processes , . Other non-thermal applications include percutaneous electrical stimulation (PENS), iontophoresis, radiofrequency (RF), infra-red and ultraviolet therapies. 1981;9:133-152. Devices such as transcutaneous electrical neuromuscular stimulation (TENS), interferential current (IFC), direct current (DC), micro-current (MENS), high-voltage stimulation, and electric muscle stimulation (EMS) have their own unique electromagnetic signature but are generally non-thermal within the normal range of patient intensity values.
