Whiteboard
Albert Stallion invented whiteboards while working at Alliance in the 1960s. Alliance (now known as PolyVision) produced enameled steel for architectural cladding, but Stallion noted it could also potentially be used as a writing surface. Stallion later left Alliance to form his own whiteboard production company, MagiBoards.
Aiken tube
The Aiken tube was the first successful flat panel black and white television. Originally designed in the early 1950s, a small number of tubes were built in 1958 for military use in a collaboration with Kaiser Industries. An extended patent battle followed with a similar technology developed in the United Kingdom and planned commercial production for the home market never started. Further development was carried out by a number of companies, including Sinclair Electronics and RCA after the patents had expired.
