Title: Innovations by David M Eissenberg
Introduction
David M Eissenberg is an accomplished inventor based in Oak Ridge, TN (US). He holds a total of 4 patents that showcase his expertise in developing innovative technologies. His work primarily focuses on noninvasive monitoring systems and diagnostic methods for electric motor-operated devices.
Latest Patents
One of Eissenberg's latest patents is a noninvasive valve monitor using an alternating electromagnetic field. This invention involves the careful placement of electrical coils on the outside of a valve body. An alternating current passing through these coils generates an electromagnetic field that interacts with the valve internals. As the position of the valve's internal components changes, the electromagnetic field's intensity and polarity also vary. A passive receiver coil detects these changes, providing valuable information about the position and motion of the valve internals.
Another significant patent is the motor current signature analysis method for diagnosing motor-operated devices. This method allows for the remote monitoring of electric motor-operated devices, such as motor-operated valves. By applying frequency domain signal analysis techniques to the motor current signal, various operating parameters can be distinctly identified. This diagnostic approach does not require special equipment to be installed on the device, making it suitable for use in both accessible and hostile environments.
