A frame comprises the conductive material that is configured to receive a driven right leg (DRL) signal based on the voltage signals from the at least three electrodes.

An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor is configured to execute the instructions to receive, from a sensor of a surgical instrument, environmental condition information associated with the surgical instrument and detected by the sensor while the surgical instrument is disconnected from an external power source, the surgical instrument including circuitry configured to be powered and operate only while the surgical instrument is connected to the external power source, determine, based on the environmental condition information, an operational condition of the surgical instrument, and provide a notification indicating the determined operational condition of the surgical instrument.

Various embodiments concern video patient monitoring with detection zones. Various embodiments can comprise a camera, a user interface, and a computing system. The computing system can be configured to perform various steps based on reception of a frame from the camera, including: calculate a background luminance of the frame; monitor for a luminance change of a zone as compared to one or more previous frames, the luminance change indicative of patient motion in the zone; and compare the background luminance to an aggregate background luminance, the aggregate background luminance based on the plurality of frames. If the background luminance changed by more than a predetermined amount, then the aggregate background luminance can be set to the background luminance, luminance information of the previous frames can be disregarded, and motion detection can be disregarded.
