Latest Patents

Wiegand held a patent for a "Read head for Wiegand wire." This invention features an E-core with a pick-up coil for the '1' bit wound on one outer leg and a separate pick-up coil for the '0' bit wound on a second outer leg. The E-core is constructed from a combination of thin and thick ferromagnetic E-laminae, which are strategically spaced apart. The design includes appropriately polarized magnets between the thin and thick laminae in each leg. This configuration establishes distinct magnetic fields that enable the read head to accurately detect and differentiate between '1' and '0' bits as they pass across the reading fields.
