A method and apparatus for operating a stirring mechanism for a container which is filled with a medium, wherein a value for the rotation speed of the stirring mechanism, which is predetermined for operating the stirring mechanism with a low level of energy consumption and stored in a memory, is set by an actuation and evaluation device such that reduced energy consumption by the stirring mechanism is achieved while at the same time the medium is thoroughly mixed.

A vehicle, method, and track control system for sensing the temperature of a track and controlling the vehicle's speed based on the temperature of the track. The track temperature may be sensed by a sensor embedded in a portion of the track, such as in a drive lug, a tread bar, or portion of the carcass. The temperature of the track may also be used to alert an operator of a track temperature issue or request that the operator reduce the speed of the vehicle.

Systems and methods provide a travel control system to augment a supplemental object detection system of a material handling vehicle. Speed limits can be calculated for material handling vehicles based on properties of the vehicle, and a field of view of the object detection systems of the material handling vehicle. For given steer angles or ranges of steer angles, the speed of the material handling vehicle can be limited to ensure that the vehicle could stop before contact with a newly-detected object that was previously outside the field of view of the object detection system.

A positioning control device according to an embodiment includes an amplifier that includes a converter that rectifies and outputs an AC power supply to bus-bars; a smoothing capacitor that smoothes an output of the converter and generates a bus voltage; a regenerative resistance and a regenerative transistor; an inverter that supplies a drive current; and a command generation unit that generates a position command value for positioning control of a mechanical load in accordance with a command pattern. The inverter is connected between the bus-bars and supplies the drive current. The command generation unit acquires a regenerative-power-amount estimated value and an energy value storable in the smoothing capacitor; and on the basis of a result of a comparison between these values, it decides whether to use the position command value on the basis of the command pattern.

A method of controlling a tractor/baler combination includes advancing a tractor/baler combination through a swath or windrow of a harvested crop material with a tractor PTO operating at a constant speed to power a drive of a baling chamber of the baler and the baler operating to pick up harvested crop material; assessing the flowrate of the harvested crop material in the baler and the torque of the baling chamber drive; comparing the flowrate with an optimal flowrate and the torque of the baling chamber drive with an optimal baling chamber drive; and, if the assessed flowrate differs from the optimal flowrate or the assessed torque of the baling chamber drive differs from the optimal torque by more than a predetermined amount, changing the speed of advancement of the tractor/baler combination, and changing the flowrate in the baler and the torque of the baling chamber drive.
