A speed limiting device may include a communicator configured to communicate with a tire air pressure monitor, a steering angle detector, a yaw rate detector and an engine controller of a vehicle; a storage configured to store limited speed information corresponding to slip information, in a form of a table; and a controller configured to acquire slip information based on a steering angle detected by the steering angle detector and a yaw rate detected by the yaw rate detector when abnormality information is received from the tire air pressure monitor, to check a limited speed corresponding to the acquired slip information, and to output the checked limited speed to the engine controller.

A battery pack for use in providing starting power for a starter motor of an internal combustion engine and to supply power to one or more auxiliary loads. The battery pack includes an outer housing that encloses a plurality of battery cells. The battery pack further includes a control module. The control module includes a processing circuit configured to control one or more functions associated with the internal combustion engine and an interface circuit configured to interface with 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.

A method for controlling PTO clutch engagement includes determining a first change in clutch speed based on an inertial load of a PTO implement. The method also includes determining a second change in clutch speed based on a threshold amount of energy of a PTO clutch. The method further includes determining a third change in clutch speed between the first change in clutch speed and the second change in clutch speed. The method also includes adjusting a clutch current based on the third change in clutch speed.

An engine control strategy for a marine vessel propulsion system receives a request for a gear from among plural transmission gears, determines an engine speed for the requested transmission gear shift, adjusts the engine to the determined speed for a predetermined amount of time, and prevents the requested transmission gear shift from occurring for the predetermined amount of time while maintaining the engine at the predetermined speed. After the predetermined amount of time elapses, the requested shift is allowed to occur.

An agricultural vehicle includes an engine, a transmission driven by the engine, and a controller. The controller, in operation, adjusts a gear ratio of the transmission using an algorithm. The algorithm, in operation, performs the following steps: reduce a torque capacity of a first offgoing clutch of the transmission to a first torque target, reduce the torque capacity of the first offgoing clutch to a second torque target while adjusting the torque capacity of a first oncoming clutch of the transmission to a third torque target, such that the gear ratio of the transmission is modified in a first direction, and increase the torque capacity of the first oncoming clutch to a desired torque capacity.

A system includes an engine, a transmission driven by the engine, and a controller. The controller is configured to receive a speed input, receive feedback indicative of a load of the engine at a current engine speed, compare the load to a predetermined load threshold at the current engine speed, determine an expected engine speed based at least on the current engine speed, a current gear ratio, and an expected gear ratio, determine an estimated engine power at the expected engine speed and a current engine power at the current engine speed, and command a gear downshift when the load is greater than or equal to the predetermined load threshold and when the estimated engine power is greater than the current engine power.

A small air-cooled internal combustion engine includes an aluminum engine block including a cylinder extending along a longitudinal cylinder axis and a block mounting surface, a piston configured to reciprocate within the cylinder, a crankshaft coupled to the piston and configured to rotate about a crankshaft axis in response to reciprocation of the piston, and an aluminum crankcase cover including a cover mounting surface. The block mounting surface contacts the cover mounting surface. The block mounting surface and the cover mounting surface are both positioned at an angle to the crankshaft axis and the angle is not 90 degrees.

The invention relates to a method for correcting the thrust vector created by a thrust unit associated with electrical correction means of the thrust vector. Such a thrust unit comprises a mechanical rotor moved in rotation by a rotary shaft of an internal combustion engine in response to a power command. Such a method comprises a step of generating this latter in order to reduce the error value between a rotation speed setpoint and a measured rotation speed of the shaft of the internal combustion engine and thus to correct the speed of the shaft of said internal combustion engine. The method also comprises a step of generating an actuation command of thrust vector electrical correction means generated based on the error value independently of the speed correction of the shaft of the internal combustion engine.

A method includes detecting a change in a loading condition on an engine based on use of an implement system including a pump driven by the engine, an actuator fluidly coupled to the pump, and an implement repositionable with the actuator. The change in the loading condition is detected based on a variation in a command signal from a joystick that controls movement of the implement, an outlet pressure of the pump, a displacement of the pump, and/or an engagement signal of a clutch positioned to selectively couple the pump to the engine. The method further includes commanding a fueling system to increase an amount of fuel provided to the engine and/or an air handling system of the machine to increase an amount of air and/or a boost pressure of the air provided to the engine in response to detection of an increasing loading condition based on the variation.
