Abstract: A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly and an end effector. The body assembly includes a trigger and a casing configured to couple with the transmission assembly. An information transmission system transmits instrument information received from a sensor, for example, to a secure server via a secure gateway connected to the instrument. The instrument may be previously tested on a calibration kit to pre-determine and load surgeon-specific settings onto the instrument prior to use.

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 process for bonding a material into a solid surface material that includes the steps of a) etching a pattern into a solid surface material; b) providing a contrasting colored compound; c) applying the contrasting colored compound into the etched pattern within a predetermined time; and d) allowing the applied material to harden and form a chemical bond between the solid surface material and the contrasting colored compound.

Abstract: An improved water tight, chambered planing pontoon assembly incorporates a hollow shell with a cross sectional shape in the form of an upper portion and lower portion. The upper portion of the shape is generally semi-cylindrical extending downward and terminates with opposing chines extending the full length of the tube. The lower portion of the shape is formed by equal and opposing planing surfaces which extend upward at acute angles from a vertical center line, then turn outward, perpendicular to the vertical center line, meeting at the chines. The tube terminates on the bow end with an elongate semi-cone and on the opposite end with a water tight bulkhead. The upper and lower portions of the tube are formed of one homogeneous sheet of metal. The semi-cone with opposing chine portions is formed of one homogeneous sheet of metal.

Abstract: In a water injection well, in place of corrosion inhibitors, the internal surface of a lower section of the casing is protected from corrosion by one or more galvanic sacrificial anodes placed in the section of casing. The anodes are mounted on a metal member which is connected to or suspended from the tubing or a well packer. The metal member extends below a certain point in the well into the section of casing. The metal member may be a tail pipe or it may be a wireline retrievable member specially prepared for this purpose. Anodes made of an aluminum alloy are especially suited to this corrosion protection system.

Abstract: A fluid pressure actuated piston is slidably carried in a fluid pressure actuated cylinder which, in turn, is slidably carried in a fixed carrier. Movement of the cylinder is resisted by a deformable tube frictionally engaged with a fixed circular member. A predetermined fluid pressure acting across a differential area wall portion of the cylinder generates a force overcoming the frictional resistance of the deformable tube engaged with the fixed circular member thereby advancing the cylinder in the direction of movement of the pressurized piston. The output force of the piston is substantially unaffected by the force imposed on the cylinder.
