Latest Patents
Wiegand's latest patents include innovative designs that utilize shaped magnetic fields. One of his patents, titled "Pulse generator with shaped magnetic field," describes a Wiegand wire module that is excited by a non-uniform field. This field can vary in time either symmetrically or asymmetrically, allowing for a switch in the state of the Wiegand wire. This process induces a pulse in the pickup coil of the module, resulting in an output pulse that is significantly greater than that obtained through symmetric excitation using a uniform field.
Another notable patent is "Pulse generation by changing magnetic field." This invention features a pulser unit composed of two high-strength magnets that establish an intense magnetic field between them. The Wiegand wire module is mounted in the pulser unit, where it is subjected to the magnetic field. The introduction of a low reluctance element adjacent to the working surface distorts the magnetic field, causing the Wiegand wire to switch state and generate an output pulse. The removal of the low reluctance element allows the field to revert, inducing another output pulse in the pickup coil.
