    Abstract: A printed circuit board is disclosed. The printed circuit board comprises a substrate having a top surface and a bottom surface. A ground plane is on the bottom surface. A signal trace is on the top surface along a first direction. At least two isolated power planes are on the top surface adjacent to opposite sides of the signal trace, respectively. A conductive connection along a second direction couples to the two power planes, across the signal trace without electrically connecting to the signal trace, wherein the signal trace doesn't pass over any split of the ground plane.

    Abstract: A dual mode control system for a hydraulic circuit (200) having a variable displacement pump (216) includes at least two actuators, each controlled by a respective valve. The valves are connected in series with a pressure sensor (250) measuring a pressure of fluid between the first valve (224) and the second valve (234) and relaying a signal to the electronic controller (202). The electronic controller (202) operates in a first mode, varying the displacement of the pump (216) based on a command signal operating at least one of the valves, and operates in a standby mode, varying the displacement of the pump (216) based on the signal from the sensor, when both valves are in their respective neutral positions.

    Abstract: A control system for a machine is disclosed. The control system may have a power source, an operator input device configured to generate a first signal indicative of a desired mode of power source operation, and a work implement driven by the power source. The control system may also have a controller in communication with the power source and the operator input device. The controller may be configured to classify a currently performed work implement task and select an output map based on the classification of the currently performed work implement task and the first signal. The controller may further be configured to control the power source operation using the output map.

    Abstract: The air circulation fan associated with a radiator of some machines may include an automatic reversing purge cycle that is utilized to dislodge material from the radiator and/or intake screen of the cooling system housing. The purge cycle is locked out when a person may be in the vicinity of the air intake screen of the machine. A controller determines that a person may be in the vicinity of the air intake screen when the machine is idle stationary, such as by determining that a parking brake is engaged. By locking out the purge cycle during machine idle stationary conditions, the risk of blowing dislodged dirt and/or debris onto a person, who may be servicing the machine or accessing an operator station, can be avoided.
