Dorne & Margolin Inc.

Dorne & Margolin Inc. was an American communications antennae research, development, and manufacturing company, particularly focused on airborne communication and navigation antenna systems for military and commercial use. The business was originally founded in 1947 by Arthur Dorne and Joseph Margolin, formerly of the Antenna Design Section of Airborne Instruments Laboratory, as a consulting firm, expanding to include research and manufacturing facilities in Bohemia, Suffolk Co., New York. The company was acquired in the 1980s by the United Capital Corporation and managed through its subsidiary Metex Manufacturing Corp. until 1998 when Dorne & Margolin was sold to AIL Systems Inc. and merged into AIL's Antenna Products & Technologies Division (followed, two years later, by AIL Systems merger with EDO Corporation).

 * US3951134A. Malech, Robert G. Apparatus and Method for Remotely Monitoring and Altering Brain Waves. 20 Apr. 1976, filed 5 Aug. 1974. Assigned to Dorne and Margolin Inc. "Apparatus for and method of sensing brain waves at a position remote from a subject whereby electromagnetic signals of different frequencies are simultaneously transmitted to the brain of the subject in which the signals interfere with one another to yield a waveform which is modulated by the subject's brain waves. The interference waveform which is representative of the brain wave activity is re-transmitted by the brain to a receiver where it is demodulated and amplified. The demodulated waveform is then displayed for visual viewing and routed to a computer for further processing and analysis. The demodulated waveform also can be used to produce a compensating signal which is transmitted back to the brain to effect a desired change in electrical activity therein." https://patents.google.com/patent/US3951134A/en
