2,543,425 Issued 27 February 1951. Squeezable Waveguide for
(Electrical) Line Stretching. This is the delta b waveguide phase
2,581,819 Issued 8 January 1952. Coaxial Termination for Noise Diode.
Provides a means for inducing filament vo1tage into the center
conductor of a matched coaxial line.
2,681,414 Issued 15 June 1954. Automatic Frequency Control Circuit.
Provides a means for locking an oscillator frequency to a resonant
system using an on-off type of control.
2,703,362 Issued 1 March 1955. Frequency Finder System. This is the so-
called Strandberg circuit for infinite receiver resolution for
2,705,756 Issued S April 1955. Automatic Frequency Control System.
Provides a means for locking an oscillator frequency by using a
transitron oscillator as a sweep generator for search, and as a DC
amplifier for feedback control.
2,750,564 Issued 12 June 1956. Frequency Monitoring Circuit. Provides a
means by which a resonant cavity can be used to provide a pip for a
2,761,141 Issued 28 August 1956. Continuously Varying Dielectric
Constant Electromagnetic Lens. Provides a means for producing
continuously varying dielectric constant material by compressing
polyfoam, or foamed polystyrene.
2,905,902 Issued 22 September 1959. Microwave Frequency Discriminator.
Provides a means for realizing an intrinsically-balanced frequency
discriminator for which the resonant circuit determining the center
frequency can be varied in frequency over a wide range.
3,143,655 Issued 4 August 1964. Photosensitive Switching Device in a
Waveguide. This is a patent for a photomodulated resistance for use
as a non-mechanical switch, or as an optical coupler.
1997 A patent was applied for titled, System and Method for Factoring a
Merged Wave Field Into Independent Components. It presents method
using digital processing to overcome the Cocktail Party Effect. In
doing this it isolates a single sound source from several. This has
application in hearing aid devices to change a confusion of sound
sources into that of a single source selected by the user.
