Abstract
Inductive identification systems and methods are described. The system may include an inductive detector configured to identify objects having inductive identifiers. An inductive detector may include conductive coils and inductance readout circuitry for measuring an inductance of each coil. An inductive identifier may include a conductive pattern configured to induce a desired inductance in the coils of the inductive detector. An inductive identifier may include a film having openings, each opening configured to be disposed over a corresponding coil to induce differing inductance changes in the corresponding coils. A pattern of inductance values may be determined and used to identify the object. The detector may be implemented in a cassette recess of an infusion pump system. The inductive identifier may be disposed on a pump cassette configured to be received in the cassette recess and identified based on an inductive interaction between the inductive detector coils and the inductive identifier.
