Abstract: Measurements made by a multi-component induction logging tool are corrected for tool eccentricity in a deviated borehole. The eccentricity angle is determined from single frequency skin-effect corrected data and is then used to correct multifrequency data. Multifrequency focusing is then applied to the corrected multifrequency data. An inversion is then used to recover formation resistivity and relative dip and azimuth of the borehole.

Abstract: The invention is related to methods and apparatus that use a visual sensor and dead reckoning sensors to process Simultaneous Localization and Mapping (SLAM). These techniques can be used in robot navigation. Advantageously, such visual techniques can be used to autonomously generate and update a map. Unlike with laser rangefinders, the visual techniques are economically practical in a wide range of applications and can be used in relatively dynamic environments, such as environments in which people move. One embodiment further advantageously uses multiple particles to maintain multiple hypotheses with respect to localization and mapping. Further advantageously, one embodiment maintains the particles in a relatively computationally-efficient manner, thereby permitting the SLAM processes to be performed in software using relatively inexpensive microprocessor-based computer systems.

Abstract: A method and apparatus for synchronizing digital and analog/mixed signal modules in a test site of an open architecture test system is disclosed. Event triggers from digital modules are routed to an ASYNC module, which selectively distributes them to analog/mixed signal modules. When an event occurs, the trigger may activate an analog/mixed signal module to perform a certain operation. The ASYNC module may also receive triggers from the analog/mixed signal modules and selectively distribute them back to the digital modules or analog/mixed signal modules. The digital modules can be programmed to wait for an analog/mixed signal module to complete an operation, as indicated by a trigger received from that analog/mixed signal module, before continuing. Because embodiments of the present invention enable synchronization of digital and analog/mixed signal modules under pattern control, synchronization can be very precise and repeatable as compared to synchronization from a site controller.

Abstract: The instantaneous value of an intermediate waveform I is the instantaneous value of a unipolar waveform U multiplied through amplification by an upscaling factor UF of 1.5. A plateau value P is subtracted from the intermediate value I, and the result of this subtraction is multiplied by a multiplication factor MF of 0.6. The result of the multiplication is added to the plateau value P, which sum becomes an auxiliary waveform A. During the ‘fall-below’ periods F, the value of a combined waveform C is arranged to follow whichever is the highest of the auxiliary value A and the plateau value P. Outside the fall-below periods, the value of the combined waveform C follows whichever is the highest of the unipolar value U and the plateau value P. This combined waveform C has, for a given plateau level P, a narrower fall-below window. Phase-chopping thus has an effect on the power of the output signal over a greater range of the cycle than can be provided by the corresponding prior art arrangement.

The data set is updated with the normalized matrix of data.

Abstract: A data logger analyzes temperature data associated with a product passing through a conveyor oven and provides a visual indication indicating whether the product's temperature profile is within acceptable limits. Thus, an operator need not download captured temperature data to a computer in order to determine whether the oven settings produce a product profile that is within acceptable limits. In one embodiment, the data logger stores criteria for an acceptable product profile, and collects the temperature data and analyzes whether the temperature profile data is within the acceptable limits of the criteria. In another embodiment, a button and a pass/fail indicator are located externally on data logger. An operator depresses the button in order to request whether the product profile passed or failed the criteria. In response to depressing the button, the pass/fail indicator provides visual indication of whether the current oven settings produce an acceptable product profile.

Abstract: There is provided a method for generating a probability distribution for a desired variable. A hyper parameter density function is provided, from which values are randomly selected. The selected hyper parameter value is used to compute an input variable value. A value is randomly selected from each input variable probability density function. These values are input into a physics model to compute an output value. This process is repeated to generate numerous output values, which are then used to construct an output value probability density function. After the output value probability density function is constructed, output value sensor data is obtained. The output density function is updated using the sensor data and a probabilistic evaluation of the hyper parameters. Improved predictions are iteratively made with the updated output distribution.
