Abstract
In various embodiments, a surgical console may include a pneumatic valve to drive a pneumatic tool coupled to the surgical console. The console may further include a controller operable to control and adjust the valve open/close cycle times according to a valve duty cycle. The valve may switch between ports (valve open time for a first port and valve close time for a second port) such that a total valve time may approximately equal the valve open time plus the valve close time. The valve duty cycle may indicate a percentage of the total valve time for the controller to signal the valve to open and may include an adjustment that corresponds to a signal timing of the open and/or closed valve positions that will result in open and closed operating pressures above a predetermined threshold.
