Title: Innovations by James H Ott
Introduction
James H Ott is a notable inventor based in Akron, OH, with a remarkable portfolio of 15 patents. His work primarily focuses on advancements in metal detection technology, showcasing his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is for a temperature compensation system for a ground-piercing metal detector. This hand tool features a ground-piercing probe that can be manually inserted into the soil. The probe contains a chamber housing an inductor connected to metal detection circuitry. A pulse generator applies current pulses to the inductor, inducing eddy currents in buried target objects. After the pulse terminates, the decaying coil voltage is sampled at various times to detect the presence, range, and type of metal in the object. The system compensates for signal variations caused by temperature changes when the probe is inserted into the soil. This is achieved by detecting a signal proportional to the coil current during the pulse and subtracting a scaled portion of that signal from the voltage samples.
Another significant patent involves a circuit for detecting the metal type of a target object. This hand tool also features a ground-piercing probe with a chamber housing at least one inductor connected to metal detection circuitry. The preferred circuitry includes a pulse generator that applies current pulses to the inductor, inducing eddy currents in buried target objects. The decaying coil voltage is sampled to determine the presence, range, and type of metal in the object. The design incorporates an asymmetric magnetic field pattern aligned with a directional sensitivity indicator on the handgrip, enhancing the tool's effectiveness.
