John Adam Presper "Pres" Eckert Jr. was an American electrical engineer and computer pioneer. With John Mauchly, he designed the first general-purpose electronic digital computer (ENIAC), presented the first course in computing topics, founded the Eckert–Mauchly Computer Corporation, and designed the first commercial computer in the U.S., the UNIVAC, which incorporated Eckert's invention of the mercury delay-line memory.
John Hopkinson, FRS, was a British physicist, electrical engineer, Fellow of the Royal Society and President of the IEE twice in 1890 and 1896. He invented the three-wire (three-phase) system for the distribution of electrical power, for which he was granted a patent in 1882. He also worked in many areas of electromagnetism and electrostatics, and in 1890 was appointed professor of electrical engineering at King's College London, where he was also director of the Siemens Laboratory.
Elisha Gray was an American electrical engineer who co-founded the Western Electric Manufacturing Company. Gray is best known for his development of a telephone prototype in 1876 in Highland Park, Illinois. Some recent authors have argued that Gray should be considered the true inventor of the telephone because Alexander Graham Bell allegedly stole the idea of the liquid transmitter from him. Although Gray had been using liquid transmitters in his telephone experiments for more than two years previously, Bell's telephone patent was upheld in numerous court decisions.
Eric Roberts Laithwaite was a British electrical engineer, known as the "Father of Maglev" for his development of the linear induction motor and maglev rail system after Hermann Kemper.
First to file and first to invent are legal concepts that define who has the right to the grant of a patent for an invention. Since March 16, 2013, after the United States abandoned its "first to invent/document" system, all countries have operated under the "first-to-file" patent priority requirement.
The invention of the telephone was the culmination of work done by more than one individual, and led to an array of lawsuits relating to the patent claims of several individuals and numerous companies. Notable people included in this were Antonio Meucci, Philipp Reis, Elisha Gray and Alexander Graham Bell.
Electromagnetic suspension (EMS) is the magnetic levitation of an object achieved by constantly altering the strength of a magnetic field produced by electromagnets using a feedback loop. In most cases the levitation effect is mostly due to permanent magnets as they have no power dissipation, with electromagnets only used to stabilise the effect.
John Stone Stone was an American mathematician, physicist and inventor. He initially worked in telephone research, followed by influential work developing early radio technology, where he was especially known for improvements in tuning. Despite his often advanced designs, the Stone Telegraph and Telephone Company failed in 1908, and he spent the remainder of his career as an engineering consultant.
The invention of radio communication was preceded by many decades of establishing theoretical underpinnings, discovery and experimental investigation of radio waves, and engineering and technical developments related to their transmission and detection. These developments allowed Guglielmo Marconi to turn radio waves into a wireless communication system.

Free World Trust v Électro Santé Inc, [2000] 2 S.C.R. 1024, 2000 SCC 66, is a leading Supreme Court of Canada decision on patents, namely claim construction and the necessity to identify essential elements and non-essential elements. Along with the related decision, Camco v. Whirlpool (2001), 9 C.P.R. (4th) 129 (SCC), the Supreme Court of Canada rejected the doctrine of equivalents applied in the United States and adopted the doctrine of purposive construction, as originally applied by the United Kingdom House of Lords in Catnic v. Hill & Smith. This was a landmark decision as it resolved the uncertainty in Canadian case law between the two doctrines.
Telecommunications engineering is a subfield of electronics engineering which seeks to design and devise systems of communication at a distance. The work ranges from basic circuit design to strategic mass developments. A telecommunication engineer is responsible for designing and overseeing the installation of telecommunications equipment and facilities, such as complex electronic switching system, and other plain old telephone service facilities, optical fiber cabling, IP networks, and microwave transmission systems. Telecommunications engineering also overlaps with broadcast engineering.
Anadish Kumar Pal is an Indian inventor, poet, and environmentalist.
Perepiteia is claimed to be a new generator developed by the Canadian inventor Thane Heins. The device is named after the Greek word for peripety, a dramatic reversal of circumstances or turning point in a story. The device was quickly attributed the term "perpetual motion machine" by several media outlets. Due to the long history of hoaxes and failures of perpetual motion machines and the incompatibility of such a device with accepted principles of physics, Heins' claims about Perepiteia have been treated with considerable skepticism.
James R. Wait was a Canadian electrical engineer and engineering physicist. In 1977, he was elected as a member of National Academy of Engineering in Electronics, Communication & Information Systems Engineering for his contributions to electromagnetic propagation engineering as it affects communication and geophysical exploration.
Charles Grafton Page was an American electrical experimenter and inventor, physician, patent examiner, patent advocate, and professor of chemistry.
Larry W. Fullerton was an American inventor best known for the invention of ultra-wideband technology, correlated magnetics, and a number of other industrial, military, and consumer technologies. He co-founded Time Domain Corporation in 1987 and Cedar Ridge Research in 2006. He holds more than 500 patents around the world for technologies as diverse as ground sonar, new magnetics technology, and radio pulse technology.
Andrea Alù is an Italian American scientist and engineer, currently Einstein Professor of Physics at The City University of New York Graduate Center. He is known for his contributions to the fields of optics, photonics, plasmonics, and acoustics, most notably in the context of metamaterials and metasurfaces. He has co-authored over 650 journal papers and 35 book chapters, and he holds 11 U.S. patents.
Salvatore Cezar Pais is an American aerospace engineer and inventor, currently working for the United States Space Force. He formerly worked at the Naval Air Station Patuxent River. His patent applications for the US Navy attracted attention for their potential energy-producing applications, but also doubt about their feasibility, and speculation that they may be scams, pseudoscience, or disinformation intended to mislead the United States' adversaries.
Yihong Qi is an engineer, professor, entrepreneur, and inventor. His work focuses on networking science and technology. Qi is currently an adjunct professor of Electrical and Computer Engineering at the Missouri University of Science and Technology. He is a Fellow of The Canadian Academy of Engineering and of the National Academy of Inventors. Qi's research has led to the founding of five independent companies.
