Richard H. Baker was hired by Electric Vehicle Control Systems in November 1976 as a full-time consultant. Baker by then had developed an alternating current synthesizer, or ACS, which the company used in its hybrid gas-electric vehicle prototype in the late 1970s.
To commercialize Baker's ACS technology, the company bought Reliance Electric in 1979. The Federal Trade Commission filed an anti-trust lawsuit against Exxon to block the acquisition of Reliance.
In 1980, Baker was deposed in Washington D.C. as part of the FTC's suit.
