ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,702,339, issued on Aug. 11, was assigned to Apple Inc. (Cupertino, Calif.).
"Protective circuitry for external sensing applications" was invented by Priyank Dineshbhai Patel (San Jose, Calif.) and Nilay D. Jani (San Jose, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Galvanic corrosion of an external electrode of a physiological signal sensor (e.g., ECG sensor) can be reduced. In some examples, protective circuitry, such as a switching circuit, can be used to reduce galvanic corrosion. In a first mode of operation (e.g., corresponding to measurement by the physiological signal sensor), the switching circuit can provide a low-impedance path (e.g....
