A work machine, such as an excavator or a backhoe, has a linkage of articulating arms for maneuvering a changeable work tool. Position and motion sensors and force sensors within the linkage provide data for a controller to determine a location of the work tool and down force applied from the linkage onto the work tool during a job. Based on characteristics of the work tool, an acceptable range of down force applied by the linkage may be assigned. If down force reaches an outer bound of the acceptable range during the job, the controller may generate an alert for the operator or adjust action by the work tool to maintain the down force within the acceptable range. Depending on the work tool and job, the down-force control can help improve work quality and guard against tool damage from dry-fire or overload conditions.

Traditionally, during ignition of a gas turbine engine, the fuel control valves are controlled to be nearly closed, in order to provide the small amount of fuel that is necessary to ignite the gas turbine engine.

Accordingly, a lightoff fuel pressure reduction system is disclosed that uses a pressure reducing regulator on a bypass flow path to temporarily reduce the pressure of fuel supplied to the fuel control valves. In this case, the fuel control valves may be maintained in a more open position during the ignition phase, which reduces the likelihood of ignition failures.

MOTOR POWER AXIAL PENETRATOR FOR INTEGRATED MOTOR MACHINE
Traditionally, integrated motor compressors utilize a radial penetrator that is connected to the motor stator via terminals and wires. This radial connection requires the motor stator to be installed within the compressor housing prior to the connection. In addition, the wires are subject to failure from rapid gas decompression. Accordingly, an axial penetrator is disclosed to provide a conductive path, through the housing, parallel to the longitudinal axis of an integrated motor machine (e.g., integrated motor compressor). This enables the connection to be performed prior to installation of the motor stator within the housing. This also enables the conductive path between the motor windings and axial penetrator to be formed, as a single integrated path, using the same conductive and insulative materials. In turn, this ensures that the entire conductive path behaves the same during decompression, reduces costs, simplifies the installation process, and increases the robustness of the connection.
A machine includes a VGT and a controller. The controller monitors, based on causing the VGT to operate according to the non-dynamic control scheme, a plurality of hardware limit parameters associated with an engine of the machine. The controller determines that a hardware limit parameter, of the plurality of hardware limit parameters, satisfies a dynamic threshold for the hardware limit parameter and thereby causes the VGT to operate according to a dynamic control scheme. The controller then monitors the plurality of hardware limit parameters and thereby determines that each hardware limit parameter, of the plurality of hardware limit parameters, satisfies a non-dynamic threshold for the hardware limit parameter. The controller therefore causes the VGT to operate again according to the non-dynamic control scheme.

This control varies the angle to maintain the power requirement, which induces the additional voltage drop across the transformer inductance to produce the required current to flow through the capacitors and balance the capacitor voltages.

COMPUTER IMPLEMENTED METHOD AND SYSTEM FOR SUPPRESSING FALSE DUMP EVENTS
A worksite tracking system uses sensor data associated with operations of a machine on a worksite to detect when the machine performs a dump event to dump material at the worksite, and to update tracking data that tracks machine operations and material movement at the worksite. If sensor data causes detection of a false dump event that did not actually occur, the worksite tracking system identifies the detected false dump event and suppresses corresponding information to update and correct the tracking data.
A method, for providing supplementary heat energy into a cabin of a work machine when a main heating system of the cabin is inactive, includes using an auxiliary heat source to impart heat to an auxiliary coolant stream. The main energy form powers a main heat source of the main heating system. Further, the method includes providing an auxiliary fluid circuit to fluidly couple the auxiliary heat source with one or more heat exchangers to supply the auxiliary coolant stream from the auxiliary heat source to the one or more heat exchangers for circulation therewithin. During the circulation of the auxiliary coolant stream within the one or more heat exchangers, the auxiliary coolant stream dissipates heat to an air flowing across the one or more heat exchangers and into the cabin to provide the supplementary heat energy into the cabin.

SYSTEM AND METHOD FOR SCHEDULING AND PACING TRAINS
A hierarchy of procedures sets pacing schedules for trains operating in a railroad network. At a train level of the hierarchy, a network coordinator sends time windows to a train indicating when the train should arrive at or depart from a siding along its track. The time windows provide flexibility for the train to adjust its pace as needed, for example, to conserve fuel. At a territory level, if the train indicates that it cannot comply with the time windows, the coordinator evaluates and adjusts pacing schedules at least for other trains sharing the same track in the territory to avoid conflicts, again providing time windows for the trains to adjust their pace as needed. At a network level, the coordinator ensures that pacing schedules adjusted for a territory also meet time windows set for trains crossing a boundary into another territory in the network.

Worksite Management System and Method for a Mobile Machine
A worksite management system directs one or more mobile machines to enhance the compaction of the terrain surface about a worksite. One or more local topography detectors that may be located on a non-compactor mobile machine measures the state of compaction of the local topography proximate to the mobile machine. An electronic controller that may be onboard the mobile machine detects if the detected state of compaction corresponds to a first topography area associated with a greater state of compaction and, if so, directs the mobile machine to a second topography area associated with a lesser state of compaction.
In a traditional bearing cap, the temperature of the oil-wetted surface that defines the oil sump may experience high temperatures, which can result in oil degradation, oil varnish, and coking. Accordingly, a bearing cap is disclosed that reduces the temperatures experienced by the oil-wetted surface.
