Abstract: An interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.

Abstract: A boat fender is particularly constructed to provide protection where needed on low freeboard boats with a minimum of rolling. The fender includes a substantially cylindrical body portion having first and second ends and an axis of elongation, and an ear portion integral with the body portion at its first end and making an angle of about 45.degree.-100.degree. (e.g. 90.degree.) with respect to the axis of elongation. Both the body portion and the ear portion are of resilient material, such as resilient plastic, and are typically hollow. An opening is provided in the ear portion large enough to receive a line therein for tying the fender to a cleat or support on a boat or dock. The contour between the ear portion and the body portion roughly conforms to the gunwale of a low freeboard boat. The fender may be attached to a boat, or it may be attached to a dock, so as to protect the boat from impacting the dock.

Abstract: A low drag buoy uses diameter reductions and spoilers of a buoyant body surface to reduce the drag. An end structure at one end of a buoyant body allows connection of that end to a line, and a number of different diameter portions are provided between the ends of the body, a step reduction in diameter being provided at a juncture between each of the different diameter portions. A spoiler is provided on the larger diameter portion at each juncture, the spoiler typically being a flipper extending circumferentially outwardly from the larger diameter portion at each juncture, with a ramp surface leading from the body to the flipper, and a substantially flat and radially extending surface of the flipper opposite the ramp. The flipper typically extends outwardly from the body about 0.04-0.08 inches, and the step reduction at each of the junctures (not counting the flipper) is about 0.1-0.125 inches. The body may have a generally ovoid, cylindrical, or other body of revolution configuration.
