Abstract: A computer-implemented method of object enhancement in endoscopy images includes capturing an image of an object within a surgical operative site via an imaging device, determining a size of the object based on the captured image of the object, displaying the captured image of the object, and displaying on the displayed captured image of the object a representation of the determined size of the object.

Abstract: A fluid piping system and pipe spools are provided. The fluid piping system has at least one pipe spool. The pipe spool has an inner wall and an outer wall with at insulating area defined at least in part by the inner and outer wall. The insulating area of the pipe spool acts to isolate any leak of cryogenic fluid in the pipe spool.

Abstract: A fail safe secondary containment system for a cryogenic liquid transport pipeline spool having a mainline liquid transport pipe and a secondary containment pipe which overlies the mainline liquid transport pipe and is affixed to the outer surface of the mainline liquid transport pipe to form a sealed annular containment space therebetween, has a cap mounted on the secondary containment pipe to provide a sealed tertiary space. A first check valve has an inlet connected to the secondary containment space for receiving fluid therefrom and an outlet connected to the tertiary containment space and a second check valve has an inlet connected to the tertiary containment space for receiving fluid therefrom and an outlet connected to the inside of the mainline liquid transport pipe.

Abstract: A cryogenic fluid piping system is provided with two or more coupled pipe spools, each spool having an inner and outer pipe, the inner for carrying cryogenic fluid. The pipe spools are also configured with a bayonet connection to allow expansion and contraction of the system without failure. A leak control device and pressure relief device are included to protect the system from catastrophic failure in the event of a cryogenic fluid leak from the inner pipe.

Abstract: A system for supporting pipe within soil or fill material which minimizes positional disturbances of the pipe despite seasonal fluctuations in atmospheric temperature is provided. The system provides a length of double walled pipe, a support member placed in the soil or fill material and a wicking device which transfers energy between the inner pipe of the double walled pipe which is typically full of a cryogenic fluid and the support. The energy transfer stabilizes the soil or fill material, typically by freezing.

Abstract: A vacuum-jacketed bayonet pipe spool system for cryogenic fluid. The pipe spool comprises a male bayonet to fit within a female bayonet of an opposing pipe and an expansion-contraction second bellows about the outer end of the male bayonet for stress-free movement.

Abstract: A method and system for dispensing cryogenic fluids, such as liquified natural gas (LNG), using a swivel bayonet joint interconnecting first and second sections of cryogenic pipe. The swivel bayonet joint includes a male bayonet joint and a corresponding female bayonet joint. An insertion stem of the male bayonet joint is dimensioned to have a very high tolerance fit within the receiving sleeve of the female joint that extends a sufficient length for formation of a vapor trap by the cryogenic fluid between the insertion end of the stem and the clamp end of the receiving sleeve. The vapor trap prohibits movement beyond the vapor trap of any cryogenic fluid passing through the joint, consequently, elastomeric seals in the bayonet joint remain insulated from extremely cold temperatures of the cryogenic fluid.

Abstract: A system and method for the delivery of cryogenic fluid, more particularly a cryogenic fuel, such as, for example, but not limited to an liquified natural gas (LNG), to a cryogenic fluid using source, and more particularly an LNG fuel source, and even more particularly an LNG fuel-operated engine. The system includes a source of a cryogenic fluid, more particularly an underground tank and with a liquid level within the underground tank source. The system includes a delivery pump to deliver cryogenic fluid from the underground tank source, to a cryogenic using source, typically an LNG fuel source above the underground tank source, with the pump located below the liquid level of the cryogenic fluid in the cryogenic fluid fuel tank.

Abstract: Cryopump apparatus for evacuating very large chambers to ultra high vacuums includes cryogenic panels alternating with radiation shields having a unique Z-configuration which optically blind the panels. The panels and shields are supported by and housed within structure having specific components slidable along one another to thereby permit necessary movement of the components when the apparatus is subjected to cool-down or warm-up. The apparatus is characterized by very high pumping speeds and is capable of cryopumping from both sides thereof.

Abstract: Cryopump apparatus includes means for supplying cryogenic fluid, means for supplying higher temperature refrigerant fluid, a panel having heat exchange surfaces on respective opposite sides thereof, with a conduit conducting cryogenic fluid therethrough, and a zigzag passageway formed by opposite sides of two radiation shields in spaced relationship with each other having the panel therebetween. The radiation shields are spaced from the panel, optically enclosing the panel therewithin. Corresponding edges of adjacent shields define open bottom channel-configured passageways for flow of gas therethrough to respective heat exchange surfaces of a panel interjacent the shields. The shields include conduits for flow of refrigerant fluid therethrough. Heat insulative positioning spacer means contact two adjacent panels and a shield therebetween, maintaining the panels and shield in spaced relationship.
