Thomson was a prolific inventor, being awarded over 700 patents. For example, he invented the induction wattmeter mechanism used in electric meters. The wattmeter is an instrument for measuring the Electric power (or the supply rate of Electrical energy) in Watts of any given circuit. He was the first recipient of the American Institute of Electrical Engineers AIEE (now Institute of Electrical and Electronics Engineers (IEEE)) Edison Medal, bestowed upon him in 1909 "For meritorious achievement in electrical science, engineering and arts as exemplified in his contributions thereto during the past thirty years. The American Institute of Electrical Engineers was a United States based organization of Electrical engineers that existed between 1884 and 1963 (when it merged with The American Institute of Electrical Engineers was a United States based organization of Electrical engineers that existed between 1884 and 1963 (when it merged with The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is an international Non-profit, professional organization The Edison Medal is presented by the Institute of Electrical and Electronics Engineers (IEEE "for a career of meritorious achievement in electrical science electrical Year 1909 ( MCMIX) was a Common year starting on Friday (link will display full calendar of the Gregorian calendar (or a Common year starting " Ironically, Thomson and Houston had been involved in a very public and acrimonious dispute with Edison in 1877-78 over etheric force.

X-Ray Safety
Thomson was one of the few pioneering physicists who were convinced of the dangers of X-Rays and radiation in a period where the subject was treated as a novelty in both science and popular culture, in blithe ignorance of health hazards. In 1896, Thomson deliberately exposed the little finger of his left hand to an x-ray tube for several days, half an hour per day. The resultant effects - pain, swelling, stiffness, erythema and blistering - were convincing for Thomson and others, but not for all. Many prominent physicians still denied that x-rays were in any way harmful, although ofttimes the denial was tempered by a qualification that the effects noted were attributable to misuse of the x-ray.

Thomson held more than 700 patents. Thomson used his patent in his company, Thomson-Houston Company, and later in General Electric.
