Title: John E Tuttle: Innovator in Detection Technologies
Introduction
John E Tuttle is a notable inventor based in Falls Church, VA (US), recognized for his contributions to detection technologies. He holds a total of 10 patents, showcasing his innovative spirit and technical expertise. His work primarily focuses on developing devices that enhance safety and efficiency in various applications.
Latest Patents
One of Tuttle's significant inventions is the armed-state detector for antitank mines. This device allows users to determine, from a safe distance, if a mine is in an 'active' state. It employs a pole-mounted sensor array to sample the weak magnetic field emitted by 'active' mines. The hand-held detector box provides audible or visual indications of the mine's status. Additionally, it enables users to perform limited diagnostics on unexploded mines, determining if the fuze has been 'killed' or simply unresponsive.
Another notable patent is the buried pipe locator utilizing a change in ground capacitance. This device detects buried pipes by sensing differences in the dielectric and conductive properties of the ground. It features a capacitor plate array that injects a low-frequency signal into the ground and samples it from two locations. As the array is moved along the ground, the operator can observe the readout to detect and mark the location of the buried pipe, effectively creating a two-dimensional map of its path.
