A method of processing downhole measurement data includes: receiving formation measurement data generated by a downhole tool during a logging-while drilling operation over a selected time period; receiving a measured depth corresponding to the selected time period based on data taken at a surface location; receiving tool rotation data generated by measurements of a rotational rate of the downhole tool taken by a downhole sensor during the selected time period; calculating a new depth of the tool as a function of time over the selected time period based on a relationship between the tool rotation data and the measured depth; and correcting an original depth of the measurement data with the new depth.

Systems and methods, including user interfaces, are provided for implementing searches using contextual information associated with a Web page (or other document) that a user is viewing when a query is entered. The page includes a contextual search interface that has an associated context vector representing content of the page. When the user submits a search query via the contextual search interface, the query and the context vector are both provided to the query processor and used in responding to the query.

The invention relates to the manufacture of a unit dose of a medicament for relieving the symptoms and/or restoring and/or protecting the neurons of patients suffering from Parkinson's disease. According to the invention, bee's venom is used in an amount of between 33 and 330 micrograms inclusive, for the manufacture of a unit dose for subcutaneous injection, every one to six weeks, of a medicament for relieving the symptoms and/or restoring and/or protecting the neurons of patients suffering from Parkinson's disease. The invention finds use in particular in the field of pharmacy.

A fastening device for fastening a movable element to a structure includes a support member and at least one belt retractor having a retractable belt and a fitting. The belt retractor may be fastened to a support member. The belt retractor is arranged in such a way that, if the fitting couples the structure and the movable element, the retractor prevents unrolling of the belt by more than a predefinable range if an external force, such as sudden mid-air turbulence acts on the movable element. Thus, the movable element is secured.

Borehole images obtained with MWD measurements have a mismatch with subsequent images obtained when measurements are repeated over the same depth interval after the drillstring has been raised up. The difference is attributable to stretch of the drillstring. This can be estimated by correlating the two images. The difference can also be estimated by monitoring drilling conditions such as RPM, WOB and torque on reentry.

An embodiment of a system for estimating a parameter of an earth formation includes at least one formation parameter sensor disposed at a first downhole component and configured to measure a parameter of an earth formation to generate formation parameter data, and one or more processors in operable communication with the at least one formation parameter sensor. The one or more processors are configured to perform: generating a mechanics model of at least one of the first downhole component and a second downhole component, the mechanics model based on geometrical data representing at least one of the first downhole component and the second downhole component; estimating a misalignment of the at least one formation parameter sensor by using the mechanics model; and correcting the formation parameter data based on the misalignment.

A method for estimating a time at which a pressure window relevant observation occurred relating to an event that occurred in an open borehole penetrating an earth formation includes: receiving with a processor a pressure window relevant observation that provides input to adjusting a pressure window for drilling fluid for drilling the borehole; and estimating with the processor a time window in which a physical parameter, a chemical parameter, or a process that caused the pressure window relevant observation to occur, the time window having a start time and an end time.
摘要:
A method for a driver assistance system for a vehicle is specified, wherein objects in the surroundings of a vehicle are detected on the basis of data of a system that covers the surroundings, and a potential free zone in which only no objects and/or objects which the vehicle can drive over have been reliably detected is determined. The potential free zone is verified by further vehicle and/or surroundings information.
