A surgical stapler including an anvil, a staple cartridge, and a buttress material removably retained to the anvil and/or staple cartridge. In various embodiments, the staple cartridge can include at least one staple removably stored therein which can, when deployed, or fired, therefrom, contact the buttress material and remove the buttress material from the anvil and/or staple cartridge. In at least one embodiment, the anvil can include at least one lip and/or groove configured to removably retain the buttress material to the anvil until deformable members extending from the surgical staple are bent by the anvil and are directed toward and contact the buttress material.

A cooling system after engine shut-down includes a pump, a coolant duct for a coolant, and at least one component to be cooled. The coolant duct is associated with a fuel pump. A cylinder head for an internal combustion engine and a method for operating the cooling system after engine shut-down are provided.

Provided is an internal combustion engine, comprising at least one cooling device for cooling at least one operational liquid of the internal combustion engine during and/or after operation of the internal combustion engine. The at least one cooling device has at least one heat exchanger and lines for transporting the at least one operational liquid to and from the at least one heat exchanger. The heat exchanger exchanges heat with a cooling medium, which cooling medium has during the operation of the internal combustion engine a lower temperature than the at least one operational liquid of the internal combustion engine. Heat is exchanged by the heat exchanger between the at least one operational liquid and the cooling medium, which cooling medium has before and/or during a starting operation of the internal combustion engine a higher temperature than the at least one operational liquid of the internal combustion engine.

A surgical stapler including an anvil, a staple cartridge, and a buttress material removably retained to the anvil and/or staple cartridge. In various embodiments, the staple cartridge can include at least one staple removably stored therein which can, when deployed, or fired, therefrom, contact the buttress material and remove the buttress material from the anvil and/or staple cartridge. In at least one embodiment, the anvil can include at least one lip and/or groove configured to removably retain the buttress material to the anvil until deformable members extending from the surgical staple are bent by the anvil and are directed toward and contact the buttress material.

Methods and systems are provided for adjusting a flow of coolant through a coolant system including a rear axle heat exchanger. In one example, a method may include flowing coolant through the coolant system while an engine is not operating. In another example, a method may include increasing a flow of coolant to the rear axle heat exchanger while the engine is not operating when a rear axle oil temperature exceeds a threshold temperature.

A method is provided for operating an internal combustion engine (ICE), typically together with a vehicle. A corresponding ICE and a related computer program product are also provided.

A temperature control system for an engine. The system includes a thermal storage expansion tank defining a thermally insulated interior volume for storing engine coolant. The system further includes a pump that pumps engine coolant that has exited the thermal storage expansion tank back into the thermally insulated interior volume of the thermal storage expansion tank and forces air out of the thermal storage expansion tank to store coolant in the thermally insulated interior volume when the engine is off.

A surgical stapler including an anvil, a staple cartridge, and a buttress material removably retained to the anvil and/or staple cartridge. In various embodiments, the staple cartridge can include at least one staple removably stored therein which can, when deployed, or fired, therefrom, contact the buttress material and remove the buttress material from the anvil and/or staple cartridge. In at least one embodiment, the anvil can include at least one lip and/or groove configured to removably retain the buttress material to the anvil until deformable members extending from the surgical staple are bent by the anvil and are directed toward and contact the buttress material.

Examples of techniques for controlling coolant flow in a vehicle cooling system for an internal combustion engine using a secondary coolant pump are provided. In one example implementation, a computer-implemented method includes receiving, by a processing device, engine operation data about the internal combustion engine. The method further includes detecting, by the processing device, a shutdown of the internal combustion engine. The method further includes calculating, by the processing device, an engine flow based at least in part on the block flow request and the head flow request. The method further includes, subsequent to detecting the shutdown of the internal combustion engine determining, by the processing device, an after-run condition based at least in part on the engine operation data. The method further includes activating, by the processing device, a secondary coolant pump based at least in part on determining the after-run condition.

A system and method for dissipating vehicle under hood heat accumulated during stationary engine operation at high load or RPM and/or under high temperature ambient conditions is installed in a vehicle having an engine positioned within an engine compartment, and a cooling fan selectively driven by way of a fan clutch. The system includes a controller connected to the engine and to the fan clutch. The controller determines whether the period of stationary engine operation occurs at or above a threshold engine load or RPM, at or above a threshold engine operating temperature, at or above a threshold ambient temperature, and/or for or longer than a threshold stationary engine operation duration. If so, the at least one controller increases a low idle set point of the engine and commands the fan clutch to engage or remain engaged for a cool-down period following the period of stationary engine operation.
