Title: The Innovations of Gerald R Bretts
Introduction
Gerald R Bretts is a notable inventor based in Livingston, NJ (US). He has made significant contributions to the field of magnetic article surveillance systems, holding a total of 8 patents. His work has advanced the technology used in surveillance systems, showcasing his expertise and innovative spirit.
Latest Patents
One of his latest patents is the "Surveillance system having magnetomechanical marker." This invention features a magnetic article surveillance system marker that, when armed, resonates at a frequency provided by an incident magnetic field within an interrogation zone. The marker consists of an elongated ductile strip of magnetostrictive ferromagnetic material positioned adjacent to a ferromagnetic element. When magnetized, this element biases the strip, allowing it to resonate at the specified frequency. A significant change in the effective magnetic permeability of the marker at the resonant frequency grants it a unique signal identity.
Another recent patent is the "Coded surveillance system having magnetomechanical marker." Similar to the previous invention, this system marker is designed to resonate at preselected frequencies when armed. It comprises multiple elongated ductile strips of magnetostrictive ferromagnetic material, each placed next to a ferromagnetic element. Upon magnetization, these elements bias the strips, enabling them to resonate at the preselected frequencies. The substantial change in effective magnetic permeability at these frequencies provides the marker with a distinct signal identity.
