The documents in the Philip M. Heyman papers describe the development with Thomson Consumer Electronics of a picture tube named Eagle, which was intended to prevent noise from vibrations in tubes used for generating audio/visual sound and display. Scientists named the noise microphonics. In addition, the papers explain the work of Heyman and his team to develop flat screen televisions, as well as describe the complexity of flat screen TV.

Seventeen of Heyman's lab notebooks (1963-1982) can be found in Record group 26.
