A system for draining a cooling system of a power generation system on a marine vessel includes a pump in fluid communication with the cooling system, the pump actively removing cooling water from the cooling system. An outlet drain discharges the cooling water. A controller starts the pump in response to an operator command to stop a prime mover of the marine power generation system and/or a speed of the prime mover being below a threshold speed. In one example, a temperature sensor determines a temperature of the cooling water in the cooling system, and the controller stops the pump in response to the temperature of the cooling water exceeding a threshold temperature. In another example, a sensor determines a pressure and/or a level of the cooling water in the cooling system, and the controller stops the pump in response to the pressure and/or the level of the cooling water dropping below a threshold pressure or a threshold level, respectively.

When a prescribed execution condition is satisfied at the time of transition from HV traveling (that is, traveling performed by an engine and a motor with generation of traveling driving force by the engine) to EV traveling (that is, traveling performed by the motor without generation of traveling driving force by the engine), a controller of a hybrid vehicle performs motoring (or a self-sustaining operation) of an engine and thereafter stops the engine.

A coolant pump includes a pump frame, a driving wheel driven by an engine, a pump wheel driven by the driving wheel, and a clutch which couples the driving wheel with the pump wheel. The clutch comprises a friction surface arranged at the driving wheel, and a clutch disc which corresponds to the friction surface. The clutch disk is connected with and co-rotates with the pump wheel, and is axially shiftable between an engaged and a disengaged position. An axial pretension spring pretensions the clutch disc into the disengaged position. A permanent magnet forces the clutch disc into the engaged position. An electromagnet, when energized, generates a polarization which is opposite to a polarization of the permanent magnet to reduce a total magnetic attraction force of the permanent magnet with respect to the clutch disc and to thereby push the clutch disc into the disengaged position via the pretension spring.

A cooling device for an internal combustion engine is provided. The cooling device includes a first passage connected to the internal combustion engine and circulating a coolant, a second passage connected to the internal combustion engine and circulating the coolant, a heat exchanger provided on the first passage and configured such that heat exchange is performed with respect to the coolant, a first pump provided on the first passage, a second pump provided on the second passage and an electronic control unit controlling the first pump and the second pump. The electronic control unit, when a temperature of the coolant is no lower than a predetermined temperature, drives the first pump such that a flow rate of the coolant in the first passage increases as compared to when the temperature of the coolant is lower than the predetermined temperature, and performs first control of stopping the second pump.

A hybrid intercooler system is provided to adjust an oil temperature. The system includes an air cooling unit that exchanges heat with external air passing through outer surfaces of a plurality of compressed intake air channels and cools compressed intake air passing through interiors of the compressed intake air channels. A water cooling unit exchanges heat between engine cooling water enclosing the outer surfaces of the compressed intake air channels and the compressed intake air passing through the interiors of the compressed intake air channels and cools the compressed intake air. Additionally, an oil temperature controller exchanges heat between oil and the engine cooling water that is heated by the heat exchange performed by the water cooling unit and adjusts the temperature of the oil.

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 coolant control system of a vehicle includes a pump control module and a coolant valve control module. The pump control module selectively activates a coolant pump. The coolant pump pumps coolant into coolant channels formed in an integrated exhaust manifold (IEM) of an engine. The coolant valve control module selectively actuates a coolant valve that controls coolant flow from the coolant channels formed in the IEM to a transmission heat exchanger based on a first temperature of a transmission and a second temperature of coolant within the integrated exhaust manifold of the engine.

A heat distribution device for hybrid vehicle is provided, including: an engine cooling circuit through which cooling water for cooling an internal combustion engine circulates; a MG cooling circuit through which a refrigerant for cooling a motor generator circulates; and a heat exchanger which performs heat exchange between the cooling water and the refrigerant. When it is determined based on a charging rate SOC of a battery that the battery can be charged, charging control is performed to charge the battery with electric power generated in a regenerative operation; when it is determined that the battery cannot be charged, heat dissipation control is performed to dissipate the heat generated by the regenerative operation to the engine cooling circuit side by the heat exchange between the refrigerant and the cooling water in the heat exchanger.

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.
