This is one of the first optical mouse ever made (1982). The mouse was manufactured in Santa Clara, USA by a company called “Mouse Systems”. The optical system was made of two pairs of led/photo-resistor. One pair was responsible for the detection of the vertical movements and the other for the horizontal ones. The patent for this electro-optical mouse is by Kirsch, Steven T. He invented and owns a patent on an early version of the optical mouse. After bringing multiple successful startup companies through IPO and corporate buy-out, he became a multi-millionaire. In 2007, his personal fortune was estimated at $230 million.
