Abstract: A surgical hub may have cooperative interactions with one of more means of displaying the image from the laparoscopic scope and information from one of more other smart devices. The surgical hub may have the capacity of interacting with these multiple displays using an algorithm or control program that enables the combined display and control of the data distributed across the number of displays in communication with the surgical hub. The hub can obtain display control parameter(s) associated with a surgical procedure. The hub may determine, based on the display control parameter, different contents for different displays. The hub may generate and send the display contents to their respective displays. For example, the visualization control parameter may be a progression of the surgical procedure. The surgical hub may determine different display contents for the primary and the secondary displays based on the progression of the surgical procedure.

A compositional coverage of the different analytical speciation techniques for the petroleum samples is determined using the different boiling curves. Each of the different analytical speciation techniques covers a different boiling range and produces a compositional model modeling a breakdown of components in the petroleum sample by carbon number, aromatic ring family, and heteroatom class.
