Ferromagnetic detection enhancer

摘要: An apparatus for increasing the ability to detect ferromagnetic objects by magnetization of objects. The includes at least one coil generate a magnetic field positioned in area object be detected. an electrical energy storage capacitor bank capable quickly releasing stored energy. high speed, current electronic switch transferring from thereby producing short duration, single polarity pulse. sample and hold circuit acquiring sensor data during periods when pulsed is not present. microprocessor controller control timing sequence pulse generation process. may portal handheld or head mounted applications.
