All electric motors can produce electromagnetic fields. If these fields are strong enough, they have the potential to disrupt the normal function of implanted heart devices, researchers note in ...
In this regard, MIT researchers believe they discovered a new way to wirelessly transfer power using non-radiative electromagnetic energy resonant tunneling. [ 3 ] Resonant inductive coupling or magnetic phase synchronous coupling [ 4 ] [ 5 ] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary ...
In 1971 Telectronics commenced testing samples of a new type of energy source for pacemakers, the lithium cell (lithium battery) being developed by Wilson Greatbatch and in 1972 commenced development of a range of integrated circuits capable of operation from the 2.8 volts of the cell while providing a stimulating pulse of 4.5 volts.
On September 22, Guidant issued safety advisories and recalls for 170,000 of their pacemakers, 56% of their total pacemakers. On October 18, Johnson & Johnson gave an announcement that they were exploring alternatives to the acquisition, followed by a November 2 warning that they might pull out of the deal due to the regulatory issues and legal ...
A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, [3] thus regulating the function of the electrical conduction system of the heart.
The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.
In USA Patent 6421600 these power coupling elements are electro-magnetic transmission coils embedded in the roadway and reception coils which are electrically resonant, so that they convert the magnetic flux above the road into electrical energy on the vehicle, which is entirely independent, since there is no mechanical or electrical link.
Example energy flows for a late-model midsize passenger car: (a) urban driving; (b) highway driving. Source: U.S. Department of Energy . Automobile accessory power can be transferred by several different means. However, it is always ultimately derived from the automobile's internal combustion engine, battery, or other "prime mover" source of ...
