Title: The Innovative Contributions of Lloyd E. Powell
Introduction
Lloyd E. Powell is a notable inventor based in Annapolis, MD (US). He has made significant contributions to the field of acoustical testing and leak detection, holding a total of 2 patents. His work has advanced the technology used in hydraulic actuators and pipe systems, showcasing his expertise and innovative spirit.
Latest Patents
Powell's latest patents include the "Acoustical Testing of Hydraulic Actuators" and the "Acoustic Leak Detector." The first patent describes a device that tests hydraulic actuators using acoustical transducers to identify sound sources indicative of leaks or defects. This invention allows for the determination of a graph of acoustic signals versus piston location using one acoustic transducer and one position sensor. Additionally, a correlation function can be obtained by cross-correlating the output from two spaced acoustic transducers.
The second patent, the "Acoustic Leak Detector," relates to a device designed for pipe systems. It features electronic channels that process acoustical signals from leak sources to determine the direction of signal propagation. Each channel includes a transducer, an amplifier unit, a variable delay unit, and a multiple-averager unit. This invention operates in two modes: the first mode determines the frequency and wavelength of the primary leak signal, while the second mode identifies the direction of propagation of the acoustical leak signal.
