A work apparatus has a drive motor and a work tool driven in a rotating manner by the drive motor. The work tool is at least partially covered by a protective hood which is mounted pivotably about the rotational axis of the work tool. A control unit is provided for controlling at least one component of the work apparatus. The work apparatus has a detection unit for detecting at least one position of the protective hood. The control unit is configured for controlling the at least one component of the work apparatus depending on the detected position of the protective hood. In a method for operating a work apparatus, the detection unit detects at least one position of the protective hood and supplies the information to the control unit. The control unit activates the at least one component depending on the detected position of the protective hood.

An auxiliary gearbox has a low speed input shaft driving a first plurality of accessories. A high speed input shaft drives a second plurality of accessories. The first plurality of accessories rotating about a first set of rotational axes, which are parallel to each other and perpendicular to a first plane. The second plurality of accessories rotating about a second set of rotational axes, which are parallel to each other and perpendicular to a second plane. The first and second planes extending in opposed directions away from a drive input axis of the high speed input shaft and the low speed input shaft. The low speed input shaft drives a variable speed transmission. A gas turbine engine is also disclosed.

A vehicle includes an powerplant, a manual transmission, and a clutch. A vehicle controller is programmed to automatically control operation of the clutch allowing the driver to shift gears by just operating the gear shifter. The vehicle also includes an input allowing the driver to override the controller and operate the clutch. The input is located on the gear shifter and is in electric communication with the controller. The controller is programmed to, inter alia, command the clutch to reduce clutch capacity responsive to receiving a signal from the sensor indicating grasping of the shifter.

A control device of an automatic transmission controls an automatic transmission 1 comprising a transmission mechanism 3 including a plurality of engagement elements, and a hydraulic oil supply device 4 supplying hydraulic oil to the transmission mechanism The control device of the automatic transmission comprises an engagement element control part 41 configured to use the hydraulic oil supply device to make the plurality of engagement elements change between an engaged state and a disengaged state; and a deceleration degree calculating part 42 configured to calculate a target deceleration degree of a vehicle in which the automatic transmission is provided. The engagement element control part is configured to make the engagement element in the disengaged state engage so that the vehicle decelerates if the target deceleration degree is equal to or more than a predetermined value when an increase in temperature of hydraulic oil in the automatic transmission is demanded.

Disclosed is a liquid chromatography solvent pump including a motor, a first piston, a second piston, and a variable output drive system coupling the motor to at least one of the first piston and the second piston. The variable output drive system includes a gearbox configured to provide a non-equal ratio between an input from the motor and an output delivered to at least one of the first piston and the second piston. The first piston and the second piston are configured to deliver a flow of solvent in a liquid chromatography system.
