20120026293 | METHOD AND MEASURING ASSEMBLY FOR DETERMINING THE WHEEL OR AXLE GEOMETRY OF A VEHICLE - In a method for determining a wheel or axle geometry of a vehicle, the following steps are provided: illuminating a wheel region with structured and with unstructured light during a motion of at least one wheel and/or of the vehicle; acquiring multiple images of the wheel region during the illumination, in order to create a three-dimensional surface model having surface parameters, a texture model having texture parameters, and a motion model having motion parameters of the sensed wheel region; calculating values for the surface parameters, the texture parameters, and the motion parameters using a variation computation as a function of the acquired images, in order to minimize a deviation of the three-dimensional surface model, texture model, and motion model from image data of the acquired images; and determining a rotation axis and/or a rotation center of the wheel as a function of the calculated values of the motion parameters. | 02-02-2012 |
20130184925 | Method for Assisting a Driver of a Motor Vehicle - A method for assisting a driver of a vehicle in a driving maneuver in which the vehicle is guided automatically along a previously calculated trajectory, or the lateral guidance for travel along the trajectory is carried out automatically, and after the driving maneuver is completed, the steering of the vehicle is returned to the driver, information being provided to the driver concerning the vehicle's surroundings and suitable steering settings before and/or during the transfer of the steering to the driver. Also described is a device for carrying out the method, including a steering arrangement for steering the vehicle along a previously calculated trajectory as well as an output arrangement for outputting information concerning the vehicle's surroundings and suitable steering settings to the driver before and/or during the transfer of the steering to the driver. | 07-18-2013 |

20110114336 | Apparatus and Methods for Multi-Layer Wellbore Construction - In aspects, the present disclosure provides a monobore wellbore construction apparatus and method, which in one embodiment may include a series of overlapping expandable liner sections. In one aspect, the overlapping liner sections may be expanded and pressed to provide no gaps along the length of the liner system. In another aspect, the liner sections may include centralizers and/or circumferential seals that provide sealing functions and spaces between the overlapping liner sections. The liner sections may be lined with a suitable sealing material, including an epoxy or may be filled with cement or another desired materials. | 05-19-2011 |
20120018173 | WELLBORE TOOL WITH EXHANGABLE BLADES - A method for conducting a wellbore operation includes disconnecting a radially projecting member from a first sub without uncoupling a second sub from the first sub. The method may include also coupling the first sub to the second sub with a connector that includes an electrical connection. An associated apparatus may include a sub having at least one conductor connected to a connector; and at least one radially projecting member removably coupled to the sub. | 01-26-2012 |
20120085549 | Pump Down Swage Expansion Method - The tubular string to be expanded is run in on a running string. The swage assembly has a seal from the running string to the existing tubular and the top of the tubular string to be expanded also has a similar seal against the exiting tubular. Annulus pressure around the running string drives the swage assembly to support the expanded tubular to the exiting tubular and to continue expansion to the end of the tubular. Cementing then takes place followed by reconfiguring the swage assembly to engage the liner hanger seal with the result being a monobore connection in a single trip including the cementing. | 04-12-2012 |
20130048308 | Integrated Continuous Liner Expansion Method - An additional string is run through an existing string using a running string. With the strings overlapping an upper inflatable secures them together leaving gaps. The upper inflatable creates an upper expanded zone where the swage assembly is then built. The swage assembly has a seal and upon pressure being applied between the upper inflatable and the seal the swage assembly releases the running string and is pushed to expand the additional string until tagging a cement shoe. The running string is rejoined to the swage assembly and after cementing a lower inflatable is deployed to make a bell and to set an external packer if used. If there is an external packer the shoe releases and on the way out of the hole the upper inflatable sets a seal in the lap. | 02-28-2013 |
20130056228 | Annular Seal for Expanded Pipe with One Way Flow Feature - The seal has a base ring that expands with the underlying supporting tubular. Extending from the base ring is a pleated structure with segments folded over each other so that the run in shape is small and up against the supporting tubular for run in. The pleated segments can have internal stiffeners that also add a bias radially outwardly when the structure is freed to move in that direction. A retaining band keeps the assembly retracted until tubular expansion defeats the band to allow the unitary structure to move out radially to the wellbore or surrounding tubular. The pleated portion unfolds and spans outwardly from the base ring to retain pressure differential in one direction while allowing fluid flow in the opposite direction. The assembly can be attached to a swage device so that pressure from above into the set seal can drive one or more swage members to expand a tubular. | 03-07-2013 |
