ALEXANDRIA, Va., April 21 -- United States Patent no. 12,607,676, issued on April 21, was assigned to Allegro MicroSystems LLC (Manchester, N.H.).
"Open-circuit sensors utilizing inductive coupling" was invented by Hernan D. Romero (Buenos Aires, Argentina).
According to the abstract* released by the U.S. Patent & Trademark Office: "Systems, circuits, and methods provide for detection of open-circuit states in an external conductor using inductive coupling. An on-chip coil is used to generate a reference magnetic field. An in-package conductor loop is connected to the external conductor. When the external conductor is continuous, the reference magnetic field generates an induced current in the in-package conductor whereas no induced curre...
