With a total of two patents to his name, Gross has demonstrated his expertise and creativity in engineering.

Latest Patents

One of Erwin Gross's latest patents is a thin, planar-shaped carrier with Wiegand wires. This invention describes a reader for a disk-shaped carrier that operates with only two permanent magnets. The variation of the magnetic field necessary for detecting the Wiegand wires is achieved through flux concentrating pieces attached to the permanent magnets. This design allows for the reading of the carrier without change, even when it is inserted into the reader rotated by 180 degrees. The flux concentrating pieces are arranged symmetrically with respect to the longitudinal axis, which serves as a two-fold axis of symmetry. Additionally, to capture the Wiegand pulses, two E-shaped soft magnetic cores are included, each carrying an electrical sensor winding.

Another patent by Gross is a magnetic instrument for reading telegraphic signals, which shares similar features with his previous invention. This reader also utilizes two permanent magnets and flux concentrating pieces to detect the Wiegand wires effectively. The symmetrical arrangement of the components ensures reliable operation regardless of the orientation of the carrier during insertion.
