A change controller application, process and system tracks modification to a configuration of a computerized device by receiving a change request indicating a requested change to an existing configuration of the computerized device and preparing a change notification message identifying the requested change to the existing configuration of the computerized device. The change controller transmits the change notification message to at least one change notification recipient and determines if a change acknowledgement is provided in response. If a change acknowledgement is provided from a change notification recipient that indicates confirmation of receipt of the change notification message, the system allows the requested change to the configuration of the computerized device to take place. If the change acknowledgement is not provided from a change notification recipient, the system conditionally operates the computerized device so that a monitoring device networked to the computerized device perceives that a configuration change to the computerized device may have taken place.

A foot operable controller for a surgical instrument having a main foot pedal assembly providing either proportional or linear control signals when moved laterally and in a vertical direction. Friction between an operator's foot and the foot pedal is minimized by a foot pad having a rotating heel plate. A neutral zone between left and right control positions of the foot pedal enables the operator to move his foot freely without changing control settings. Vertical displacement of the foot pedal is indicated by a plurality of mechanical detents during both upward and downward travel. Changing detent resistance alerts the operator to the vertical position of the foot pedal, indicating that further vertical displacement will change an instrument control signal corresponding to the new foot pedal position, thus providing sensory feedback to the operator indicating a change in the functional mode when the foot pedal is moved.
