Abstract: Apparatus and methods are provided for controlling a double-acting hydraulic cylinder during a load-induced rod-extending operation, where the cylinder is activated by fluid supplied from a reservoir by a pump, and the cylinder has a rod end, a head end, a piston connected to a rod for engaging the load, the cylinder piston being urged toward the rod end by the load during the operation. The apparatus includes a cylinder activating circuit including an activation valve for providing a flow path from the pump to the cylinder head end; a flow regeneration circuit fluidly connecting the cylinder rod end and the cylinder head end and configured for providing flow from the cylinder rod end to the cylinder head end during rod extension, the regeneration circuit including a regeneration flow valve; and a controller operatively connected to the regeneration flow valve and the activation valve, the controller being responsive to rod-extending rate demands from an operator to control the activation valve to provide flow from the pump to the head end and to control the regeneration valve to provide flow from the rod end to the head end. The cylinder activating circuit also includes a return flow path and a return valve positioned in the return flow path and configured to control flow from the cylinder rod end to the fluid reservoir. Both the activation valve and the return valve are controllable by the controller independently from the regeneration flow valve.

Abstract: A four-phase dual pumping circuit has a number of stages according to the required output voltage based on an input voltage. Each stage has a first pumping unit and a second pumping unit that are mirror and identical to each other and electrically coupled to each other. The dual pumping circuit is controlled by four-phase clocks which are made from one pair of out of phase clocks. The transistors of the dual pumping circuit have special substrate connection to minimize body effects. The four-phase dual pumping circuit uses NMOSFETS for negative pumping and PMOSFETS for positive pumping.

Abstract: A skid steer vehicle has sprung suspensions, variable displacement pumps and motors connected to those pumps that drive the wheels on the vehicle as well as an electronic controller that receives signals that indicate fore-and-aft acceleration of the skid steer vehicle. Based on these signals, the controller determines whether the forward acceleration exceeds a predetermined value and locks up the rear suspensions if that value is exceeded. It also determines whether the forward deceleration exceeds a predetermined value and locks up the front suspensions if that value is exceeded. The signals can be provided by an accelerometer, a satellite receiver, wheel/motor speed sensors, sensors in the pumps that signal the specific displacement of the pumps such as their swash plate positions, or memory locations that contain previously calculated specific displacement commands that are used to drive the pumps to a particular specific displacement.
