Abstract: In one embodiment, a bathymetry system includes a base slab, multiple spacer assemblies, a decking layer, multiple computer numerical control routed blocks, a waterproof coating, and multiple floor joints. The spacer assemblies are coupled with a top surface of the base slab, the decking layer is disposed on top surfaces of the spacer assemblies, the blocks are disposed on a top surface of the decking layer, floor joints are disposed between blocks and the decking layer, and the waterproof coating is disposed on top surfaces of the blocks. The top surfaces of the routed blocks are shaped so that the blocks collectively provide a bathymetry profile, such as a bottom contour of a riverbed.

Abstract: A control system for a powertrain system includes an electronic control unit structured to receive ground speed data and load factor data. The electronic control unit determines an engine speed command to an engine and a torque command to a variable-torque transmission based upon an engine speed limit and a torque scale factor that can vary with ground speed and load factor. The commands produce an economy output of the powertrain to reduce fuel consumption.

Abstract: A control system for a powertrain in a machine includes a first sensor which generates a first signal indicative of a ground speed of the machine. The control system includes a second sensor which generates a second signal indicative of a load of an engine in the powertrain. The control system includes a third sensor which generates a third signal indicative of an operational state of the machine. The control system includes an input device which enables an operator to generate a request for a powertrain output. The control system further includes a controller in communication with the first sensor, the second sensor, the third sensor and the input device. The controller determines an engine speed command and a transmission output torque command to produce a powertrain output based at least on the first signal, the second signal and the third signal in response to the requested powertrain output.
