Abstract: A machine is configured to access force data generated by a force sensor, where the force data quantifies variation in magnitude of a force encountered by a distal portion of an elongate device during a time period in which the distal portion traveled a distance within an environment during a procedure, and where the force data includes a current value of the magnitude of the force. Based on the force data, the machine generates a graphical representation that indicates the force encountered by the distal portion at a point in the procedure relative to an entirety of the procedure, and then causes a display screen to present the graphical representation. Other apparatus and methods are also described.

Abstract: A method of detecting a tool being received in a medical system, the method including receiving, in a tool recognition assembly having a first reader with a first detection zone, the tool having a first target. The method also includes acquiring first sensor data from the first reader for the first detection zone and detecting an indication of an absence of the first target when the first sensor data is within a first pre-determined threshold range and logging the absence indication. The method also includes creating an insertion signature associated with the tool being received in the tool recognition assembly by combining, in a chronological sequence, the absence and presence indications from the first reader. The method further includes comparing the insertion signature to a predetermined set of model insertion signatures and determining a characteristic of the tool being received in the tool recognition assembly based on the comparing.
