A system including a tool recognition assembly comprising a first target reader with a first detection zone. The system also includes a tool configured to be installed in the tool recognition assembly, wherein the first reader detects a first reading indicating a presence or absence of the first target in the first detection zone during an installation of the tool in the tool recognition assembly, the detected first reading being at least a part of a detected insertion signature, and provides the detected insertion signature to initiate a comparison of the detected insertion signature to one or more model signatures.

Systems and methods for sensing presence of medical tools

An apparatus is provided to detect electrical contact between anatomical tissue and a shield conductor: a transformer; an alternating current (AC) reference frequency signal generator to inject a reference frequency signal to a primary winding of the transformer; a reactive impedance coupled in parallel with a secondary winding of the transformer between a first node and a second node; and a phase match detector circuit to detect a phase match between the reference frequency signal and a reflected reference frequency signal that is reflected from the secondary winding to the primary winding.
