Electric Field Measuring Device.
Abstract
The patent application describes an electric field measuring device that is particularly suited for being mounted on the nose boom of an aircraft for periodically measuring the atmospheric electric field intensity and orientation. The device includes a rotating assembly that includes a pair of capacitor plates, analog signal processing equipment, digital processing equipment, a slip ring assembly, orientation light transmitter and receiver assemblies and an information light transmitter. All of these elements are mounted on a rotatable shaft that is driven by an electric motor. The light from the rotating information light transmitter is received by a stationary information light receiver, the output of which is applied to the input of a stationary digital receiver and storage device. Floating D.C. power is transmitted by a brush assembly through the slip ring assembly to the rotating electrical equipment.
