Abstract: A hydraulic system for a machine includes an implement pump, a valve, and an implement valve subsystem. The implement pump includes a load sensing control, and the valve controls the flow of hydraulic fluid to the implement pump. The implement valve subsystem includes one or more implement control subsystems to control movement of an implement. The valve is an electrohydraulic proportional relief valve and includes a solenoid configured to adjust the pressure of hydraulic fluid delivered to the implement pump proportionally to a current delivered through the solenoid.

Abstract: A hydraulic system with margin based flow supplementation is provided. The hydraulic system includes a steering pump, an implement pump and a flow sharing device. The steering pump is associated with a steering circuit. The implement pump is associated with an implement circuit. The flow sharing device is disposed between the steering circuit and the implement circuit and is configured to operate in one of a first mode and a second mode. Further, the flow sharing device allows hydraulic fluid to flow from the implement circuit to the steering circuit in the first mode, when a margin pressure of the steering circuit is below a threshold value, and the flow sharing device stops the hydraulic fluid to flow from the implement circuit to the steering circuit in the second mode, when the margin pressure of the steering circuit is equal to or above the threshold value.

Abstract: A machine supports multiple selectable operating modes for operator input devices. An operator input device and associated input sensor convert physical operator actions into operator input control signals. A force feedback device, associated with the operator input device, exerts a resistive force based upon force feedback signals issued by the programmed controller. A machine subsystem includes an actuator configured to change an operational state of the machine according to machine control commands issued by the programmed controller based upon the operator input control signals. An operator input device configuration unit receives directions for specifying an operator input device configuration definition. The operator input device configuration definition specifies a mapping between the operator input control signals and the machine control commands.

Abstract: A steering system can include a steering control valve, primary and secondary sources of pressurized fluid, and a controller. The primary and secondary sources of pressurized fluid can be fluidly connected to the steering control valve. The primary source of pressurized fluid can be configured to sense a load pressure requirement from the steering control valve. The controller can be communicably coupled to the primary and secondary sources of pressurized fluid. The controller can monitor a margin pressure of the primary source of pressurized fluid. The controller can determine an operational status of the primary source of pressurized fluid based on the monitored margin pressure.

Abstract: A standard for supporting a game net above a playing surface is provided with an internal net tensioning system which allows the standard to be stored beneath the playing surface. A plurality of pre-set height stops are provided along the length of the standard to allow the net to be set at one of several different heights to accommodate the playing of different games by different playing abilities. Power cylinder mechanics permits the automatic raising and lowering of the standard with respect to the playing surface. A quick attachment system is provided for quickly and easily engaging and disengaging the net from the standard.
