20130261902 | Automatic Control of a Joystick for Dozer Blade Control - Dozers outfitted with manual or electric valves can be retrofitted with a control system for automatically controlling the elevation and orientation of the blade. No modification of the existing hydraulic drive system or existing hydraulic control system is needed. An arm is operably coupled to the existing joystick, whose translation controls the elevation and orientation of the blade. The arm is driven by an electrical motor assembly. Measurement units mounted on the dozer body or blade provide measurements corresponding to the elevation or orientation of the blade. A computational system receives the measurements, compares them to target reference values, and generates control signals. Drivers convert the control signals to electrical drive signals. In response to the electrical drive signals, the electrical motor assembly translates the arm, which, in turn, translates the joystick. If necessary, an operator can override the automatic control system by manually operating the joystick. | 10-03-2013 |
20140207331 | ESTIMATION OF THE RELATIVE ATTITUDE AND POSITION BETWEEN A VEHICLE BODY AND AN IMPLEMENT OPERABLY COUPLED TO THE VEHICLE BODY - An implement having an implement acceleration is operably coupled to a vehicle body having a body acceleration. An attitude of the implement is estimated by receiving acceleration measurements from an accelerometer mounted on the vehicle body and an accelerometer mounted on the implement. A state vector estimate is calculated based at least in part on the body acceleration measurement and the implement acceleration measurement. The state vector estimate includes a representation of the attitude of the implement relative to the vehicle body. In addition to the accelerometer measurements, angular velocity measurements can be received from a gyro mounted on the vehicle body and a gyro mounted on the implement. The state vector estimate is then calculated based at least in part on the body acceleration measurement, the implement acceleration measurement, the body angular velocity measurement, and the implement angular velocity measurement. | 07-24-2014 |

20090044945 | METHOD FOR HYDRAULIC FRACTURING OF SUBTERRANEAN FORMATION - The invention provides economically effective methods for hydraulic fracturing a subterranean formation that ensure improvement of the hydraulic fracture conductivity because of forming strong proppant clusters uniformly placed in the fracture throughout its length. One of these methods comprises: a first stage that involves injection into a borehole of fracturing fluid containing thickeners to create a fracture in the formation; and a second stage that involves periodic introduction of proppant into the injected fracturing fluid to supply the proppant into a created fracture, to form proppant clusters within the fracture to prevent fracture closure and channels for flowing formation fluids between the clusters, wherein the second stage or its sub-stages involve additional introduction of either a reinforcing or consolidation material or both, thus increasing the strength of the proppant clusters formed into the fracture fluid. Another method comprises: a first stage that involves injection of said fracturing fluid into a borehole, and a second stage that involves introduction of proppant into the injected fracturing fluid and further, involving periodic introduction of an agent into the fracturing fluid to provide formation of proppant clusters in the created fracture and channels for flowing formation fluids. Still another method comprises: a first stage that involves injection of a fracturing fluid into a borehole; a second stage that involves continuous introduction of a proppant into the injected fracturing fluid, and a third stage that involves injection of a lower-viscosity, in comparison with fracturing, fluid into the fracturing fluid, the lower-viscosity fluid, owing to the difference in viscosity compared to the fracturing fluid, penetrating into the fracturing fluid in the form of intrusions that divide the proppant into discrete clusters to form channels between them through which formation fluids to pass. | 02-19-2009 |
