Tom's Invention

In 1986 Tom Street moved from Wisconsin to Florida to help run Street Electric Corp. (machinery repair).

In 1988, at the age of 29, he was seriously injured while unloading his rail dragster from his truck, which left him paralyzed from his shoulders to his toes. He never regained the use of his arms or legs.

In 1989 Tom formed Street Electric Mfg. Co. (SEMCO) and served as a consultant for repair of heavy electrical equipment.

In 1993 he returned home to Wisconsin and designed and developed the QuadJoy, an orally-controlled Mouse, for his own use.

When Tom realized that his invention would be a godsend to anyone unable to manipulate a hand-held mouse, he collaborated with his brother Bill, an electronics engineer, and his friend Jerry, a machinist, to launch the QuadJoy via the Internet in 1994. The manufacturing and sales of the QuadJoy mouse and its accessories was incorporated into SEMCO. It has been refabricated using upgraded materials, but the design is the same as Tom's original prototype.

Tom used his '93 original QuadJoy until his untimely death in 2001.

Tom's mother, Margaret Street, has been instrumental in processing orders, and continues to oversee SEMCO's operation.

SEMCO's QuadJoy has been CE certified and is sold worldwide.
