Latest Patents

Walter Doell's latest patents include innovative designs for magnetically operated switches. One of his patents focuses on magnetic orientation-independent magnetically actuated switches. This invention involves creating an outer cylinder and an actuator cylinder from alternating ferromagnetic and non-ferromagnetic sheets. A first ferromagnetic body is attached to one end of the outer cylinder, while the actuator cylinder is positioned within a bore of the outer cylinder. The actuator pin extends beyond a bore of the first ferromagnetic body, and a second ferromagnetic body is attached to the actuator pin, forming a switch that operates independently of magnetic orientation.

Another significant patent involves implantable medical leads and systems designed to create a high impedance within a conduction path in the presence of a substantial magnetic field. This technology is particularly useful for implantable medical systems that include magnetically actuated switches. These switches are strategically placed in the conduction path to the electrode of the lead, ensuring that they open in the presence of strong magnetic fields, such as those generated by MRI machines. This design helps to reduce heating at the electrode, enhancing patient safety during medical procedures.
