Abstract
A powered surgical system includes an instrument drive unit and an instrument configured to couple to the instrument drive unit. The system also includes a detection circuit configured to supply input signal to the instrument and to output one of a first value indicating a connection of the instrument or a second value indicating a disconnection of the instrument in an asymmetric-in-time hysteresis manner. The connection of the instrument is detected within a first interval and the disconnection of the instrument is detected after expiration of a second interval that is longer than the first interval.
