A tubing set for use with a blood handling system is described that decreases the priming volume and surface area of the blood handling circuit, lowering the risk of hemodilution, platelet activation, and hemolysis. The inventive device facilitates the accessibility to individual modules for maintaining andor eliminating damages. The device also comprises means for triggering a signal as a reminder that an event is in progress, the said signal being activated by the said first means and deactivated by the said second means. The second video pipeline pre-processes VS2, wherein VS2 is the same video signal being pre-processed in the first video pipeline, one of the other forwarded video signals produced in the video input module, or a second stored video signal, producing a second pre-processed video signal. Actions designed to affect the likelihood that the resulting targeted entities will engage in the behavior may be directed to the targeted entities. Also disclosed is a method of forming a circuit element.
