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

A method of operating an imaging system includes reducing common-mode current induced on a cable connected between an imaging system and an endoscope by utilizing a common-mode choke between the cable and a circuit within the endoscope, the common-mode choke being mounted within a body of the endoscope.

Reduction of endoscope high frequency leakage current using a common-mode choke

An endoscope includes a body and a circuit board mounted within the body. A cable couples the circuit board to an imaging system. A common-mode choke is mounted within the body and is configured to electrically isolate the cable from the body at cautery frequencies. A method includes twisting a plurality of wires together to form a twisted set of wires. The twisted set of wires is wound around a core so that windings do not overlap, and so that a first winding and a last winding are separated from each other. Wires in the twisted set of wires are coupled to a plurality of wires in the cable. Also, these wires in the twisted set of wires are also coupled to the circuit board.
