Various examples are directed to systems and methods for operating a surgical instrument comprising a firing member translatable proximally and distally along a longitudinal axis between a stroke begin position to a stroke end position distal of the stroke begin position; a knife coupled to the firing member; and a motor coupled to the firing member to translate the firing member between the stroke begin position and the stroke end position. A control circuit may receive a firing signal and begin a firing member stroke by providing an initial motor setting to the motor. The control circuit may maintain the initial motor setting for an open-loop portion of the firing member stroke. The control circuit may receive firing member motion data describing a motion of the firing member during the open-loop portion of the firing member stroke and may select a firing control program based at least in part on the motion of the firing member during the open-loop portion of the firing member stroke.

The present invention is directed to a miniaturized biosensor and nanotechnology which is embedded in a variety of medical devices which can be used for real-time device location tracking and analysis, for the purpose of optimizing device positioning both at the time of initial placement and throughout its clinical use (i.e., device continuum). The continuously acquired device-specific standardized data is then transmitted through wireless communication networks to provide continuous feedback and alerts to authorized clinical providers as to device positioning, clinical performance, and presence of pathology.
