Abstract: System and method for measurement, DAQ, and control operations which uses small form-factor measurement modules or cartridges with a re-configurable carrier unit, sensors, and a computer system to provide modular, efficient, cost-effective measurement solutions. The measurement module includes measurement circuitry, e.g., signal conditioner and/or signal conversion circuitry, and interface circuitry for communicating with the carrier unit. The module communicates interface information to the carrier unit, which informs the computer system how to program or configure a functional unit on the carrier unit to implement the communicated interface, or sends the information directly to the computer system. The computer system programs the carrier unit with the interface, and the programmed carrier unit and measurement module together function as a DAQ, measurement, and/or control device.

Abstract: A jitter calculator engine that includes a core effects module, an input/output (I/O) module, and a phase lock loop (PLL) module is provided. The core effects module estimates core jitter caused by noise effects impacting a core clock network. The I/O module estimates I/O input pin switching effects on a clock network input signal. In one embodiment, the I/O module identifies a relative frequency of switching by I/O pins in the circuit design. The PLL module estimates an effect of a PLL on a signal delivered to the PLL from an I/O pin. The PLL module accounts for I/O input pin switching effects and core jitter. The jitter calculator engine may be in communication with a database and the different designs evaluated may be stored in the database so that the database becomes a repository for the different designs and may provide useful information for future designs.

Abstract: A method and apparatus is utilized to determine the bearing and/or location of sources, such as, alternating current (A.C.) generators and loads, power lines, transformers and/or radio-frequency (RF) transmitters, emitting electromagnetic-wave energy for which a Poynting-Vector can be defined. When both a source and field sensors (electric and magnetic) are static, a bearing to the electromagnetic source can be obtained. If a single set of electric (E) and magnetic (B) sensors are in motion, multiple measurements permit location of the source. The method can be extended to networks of sensors allowing determination of the location of both stationary and moving sources.

Abstract: A user in locomotion on foot during an outing may identify a grade of a surface with at least one device supported by the user. A performance parameter of the user may be determined with the device based upon the grade of the surface, which may be based upon a measured physiological parameter of the user. An average foot contact time and an average pace of a user during a first outing may be identified and a relationship between them may be determined. No other average foot contact times or average paces identified during a different outing may be used to define the relationship. A single user-specific calibration contestant may define a relationship between foot contact times of a user and corresponding paces of the user, wherein no other user-specific calibration constants are used to define the relationship.

Abstract: A method is provided for predicting a value of a designated rock or fluid property in a subterranean geologic volume. A first predicted value of the designated rock or fluid property is also assigned to a volume of a multi-dimensional, multi-scale model. A first predicted value of seismic response for the model volume is calculated from a response model using the first predicted value of the designated rock or fluid property, wherein the response model is responsive to changes in predicted values of the designated rock or fluid property. A synthetic trace is generated and iteratively compared to the corresponding trace obtained from one or more sets of actual seismic data to determine a difference while consistency is maintained between the types, scales and dimensions of values and data.

Abstract: An improved method is disclosed for collecting or assembling scalar potential data measurements that are to be subsequently prepared as a surface representation for analysis via frequency domain transform filters. Measurements are made over a geographic reference region which extends in all cardinal directions from the center of some previously determined primary region. The reference dimensions must contain the primary region and must be plural multiples of the greatest depth to be considered in analyzing the contributions to the measurements. A combined or separate improved method for delineating or defining geospatial information contributing to a scalar potential surface is disclosed. This method is implemented using traditional statistical techniques to construct an histogram from the set of values comprising a surface representation. This histogram constitutes a Spatially Correlated Potential Spectrum for the surface.

The user can also select or customize derived variables to be distinctively displayed as part of a presentation.
