By early 1973, over 60 implanted Betacel-Biotronik pacemakers were being monitored as part of the clinical investigation. [3] [6] By mid-1974, the USAEC had authorized the licensing in the United States of a Clinical Investigation Program that allowed the implantation of 50 Betacel-Biotronik pacemakers per month in major clinics in the U.S. [7]
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.
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 ...
Various resonant coupling systems in use or are under development for short range (up to 2 meters) [6] wireless electricity systems to power laptops, tablets, smartphones, robot vacuums, implanted medical devices, and vehicles like electric cars, SCMaglev trains [7] and automated guided vehicles.

The European Commission has confirmed a proposal for the mandatory introduction of ESC on all new cars and commercial vehicle models sold in the EU from 2012, with all new cars being equipped by 2014. [62] Argentina requires all new normal cars to have ESC since 1 January 2022, [63] for all new normal vehicles from January 2024. [64]
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.
SAE J3105 is a recommended practice for automated connection devices (ACD) that mate chargers with battery electric buses and heavy-duty vehicles. The practice is maintained by the SAE International with the formal title "Electric Vehicle Power Transfer System Using Conductive Automated Connection Devices Recommended Practice", and was first issued in January 2020.
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 ...
