SYSTEMS AND METHODS FOR INDUCTIVE IDENTIFICATION
First Claim
1. An apparatus, comprising:
- at least one conductive coil;
processing circuitry coupled to the at least one conductive coil and configured to (a) determine an inductance of the at least one conductive coil and (b) determine an identity of an object based on the inductance when an inductive identifier of the object is placed within a proximal distance of the at least one conductive coil.

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.
