Automatic Signal was formed in 1928 and produced the first practical traffic actuated controllers. In the 1930s the Automatic Signal line was bought by Eastern Industries, and again in the 1950s by the Laboratory for Electronics Co. (LFE.) In the 1980s Mark IV Industries bought LFE, but sold the line to Siemens in 1997. Siemens now calls the product line Eagle TCS.
