An unidentified man holds what is likely a hall effect sensor ("half effect" may be a misspelling in the original label on the photograph).
The Helipot Corporation was founded during World War II by Arnold O. Beckman of Beckman Instruments (at that time still called National Technical Laboratories) to keep up with the demand for Beckman's reliable dial, also called the helipot. In the 1950s, Helipot Corp. was reincorporated into Beckman Instruments as the Helipot Division and continued to make potentiometers and other electrical components for decades, those tiny dials becoming staples of the electronics manufacturing industry.
