Abstract: A computer-readable medium performs a method for performing a drilling operation in a formation. A plurality of predictive models are determined. Each predictive model of the plurality of predictive models is determined for an interval in the downhole formation, wherein each predictive model of the plurality of predictive models relates one or more drilling parameters of the drilling operation to a plurality of objectives for the drilling operation. A plurality of target objectives is defined. A plurality of outcomes is determined for each of the predictive models of the plurality of predictive models and the plurality of target objectives. An optimization is performed to select an outcome from the plurality of outcomes. The drilling operation is performed using the selected outcome to achieve the plurality of target objectives.

Abstract: The disclosed embodiments provide a system that manages synchronization between a profile store and a source of truth that is used to update the profile store via a real-time link. During operation, the system selects a profile for an entity in the profile store for use in verifying the synchronization between the profile store and the source of truth based on an access pattern associated with the profile store. Next, the system obtains a first set of attributes from a profile for an entity in the profile store and a second set of attributes for the entity from the source of truth. The system then compares the first and second sets of attributes to detect and correct mismatches between the first and second sets of attributes, wherein the corrected mismatches improve subsequent use of the profile in the profile store by the set of remote offerings.

Abstract: The disclosed embodiments provide a system for updating database records while maintaining accessible temporal history. The system operates by receiving a request, at a database, to select a specific instance of a record from the database at a specific point in time. In response to the request, the system reads an instance of the record from a snapshot of the database, wherein the snapshot of the database was made prior to the specific point in time. Next, the system loads one or more deltas associated with the record from the database, wherein each delta in the one or more deltas comprises the difference between a new state of the record and a prior state of the record. The system then chronologically applies the one or more deltas to the instance of the record to create the specific instance of the record. Finally, the system returns the specific instance of the record.

A processing unit for generating an input command in accordance with predefined interacting input patterns is provided. A method for generating an input command is also disclosed, wherein when an instance of touching occurs a respective input pattern is determined in at least two spatially separated input elements. An associated input command is generated from the respective input patterns as a function of input patterns which interact in a predetermined way.

Abstract: A method poses requests in a social networking site by a submitting user by a terminal connected to a communication network to a previously unknown group of receiving users is disclosed. A relationship data model is provided which comprises objects linked to each other by semantic and/or a social relations. The question, i.e. content of the request, generally includes a question text in a text format, preferably in a natural language such as English. The question text includes one or more request meta data terms, whereby each request meta data term includes an identifier symbol, a connector symbol and a connector. The at least one request meta data term is then mapped to objects of the relationship data model. This mapping results in generating at least one group of receiving users. The submitted message is finally distributed via the communication network to the group of receiving users.

Abstract: An operating device may include an operating element that is axially moveable about an axis of rotation, and a display unit arranged radially inside the operating element with respect to the axis of rotation and stationary with respect to the operating element. The display unit may be at least partially surrounded by the operating element. A control unit may control the display unit such that at least one selection region is displayed, which can be selected based on a displacement of the operating element. When a selection region is selected using the operating element, an operating function currently associated with the selection region is triggered. The operating device supports intuitive operation based on the immediate proximity of the operating element to the display unit.

Abstract: The invention relates to a detection device comprising a portable recording unit (CAM) for detecting a surrounding operating area by means of a sensor, a contactless communication interface (IF) for receiving identification data, and an analyzing unit (CTR) for analyzing the identification data and for activating the recording unit (CAM) dependent on the analysis. The advantage of the invention and the embodiments of the invention over conventional recording systems is characterized, among others, in that only work steps in a definable surrounding operating area are recorded and optionally only at specific times and/or periods of times without assistance from an operator. As an expandable system, not just audio and video streams can be recorded and analyzed but also additional surroundings data, such as temperature, humidity, etc., which can be used with respect to the audio and video data.

Abstract: Described is a circuit for receiving a differential input signal at two substantially symmetrically built up current paths and for providing an output signal therefrom. At least one current path comprises means for adjusting the timing information of the input signal to the timing information of the output signal. The adjustment can be accomplished by modifying a voltage level in the respective current path until the timing information of the output signals at least substantially represents the timing information of the input signal, e.g. by modifying an impedance or a current in the respective current path. The adjusting of the timing information is executed by applying a defined input signal with a known timing information, comparing the timing information of the resulting output signal with the timing information of the input signal, and modifying at least one voltage level in at least one of the current paths until the timing information of the output and input signals at least substantially match.
