Title: The Innovative Contributions of David L Ehle
Introduction
David L Ehle is a notable inventor based in Attica, MI (US), recognized for his significant contributions to the field of engineering and technology. With a total of 8 patents to his name, Ehle has made strides in developing innovative devices that enhance measurement accuracy and efficiency.
Latest Patents
One of Ehle's latest inventions is the Miniature Crossed Coil Gauge Having an Active Flux Ring. This device features an oriented rare earth magnet mounted on a rotary shaft, which supplies a magnetic flux directed transverse to the shaft axis. The gauge housing, constructed from an upper and lower bobbin, surrounds the magnet and supports the rotary shaft. The design includes a first and second coil wound in a crossed coil orientation around the gauge housing, encircling the magnet. A flux ring is positioned around the coils, axially aligned with the magnet. This innovative construction allows for the redistribution of magnetic flux, significantly increasing the magnetic flux measured at the surface of the coils. The gauge's compact design enables it to be directly mounted on printed circuit boards using standard electronic component mounting equipment.
