Abstract: A controller (5) controls the engaging force between a pump impeller (1a) connected to an engine (2) and a turbine runner (1b) connected to an automatic transmission (23). The controller (5) first performs feedforward control of the engaging force. The controller (5) determines a reference value and a target rotation speed based on the capacity characteristics of the torque converter (1), and if the rotation speed of the engine (2) becomes less than the reference value, performs feedback control of the engaging force so that the deviation between the target rotation speed and the rotation speed decreases. When a predetermined condition is satisfied, the controller (5) changes over from feedforward control to feedback control, even if the rotation speed of the engine (21) is not less than the reference value. As a result, the control precision of feedback control when performing a slip lock-up, is increased.

Abstract: A stop area is set in an arbitrary area where map matching processing is to be stopped, by an operation switch group or a remote controller. When a vehicle enters the stop area, the map matching processing is stopped, and when the vehicle exits from the stop area, the map matching processing is performed.

Here, since the stop area can be set in advance, it is not necessary to perform any selection operation. Thus, load on a driver during driving the vehicle can be reduced.

Abstract: An inertial (“INS”)/GPS receiver uses injected alignment data to determine the alignment of the INS sub-system when the receiver is in motion during start-up. The alignment data is determined from parameterized surface information, measured GPS velocity, and a known or predetermined angular relationship between the vehicle on which the receiver is mounted and an inertial measurement reference, or body, frame associated with the accelerometers and gyroscopes of the inertial measuring unit (“IMU”). The parameterized surface information, which provides a constraint, may be the orientation of the surface over which the vehicle that houses the receiver is moving. The receiver uses the initial GPS position to determine the location of the vehicle on the parameterized surface, and thus, the known surface orientation. The receiver then determines the roll, pitch and heading of the vehicle on the surface using the associated GPS velocity vector.

Abstract: A method for depth matching borehole images and/or core section images is disclosed wherein signals from sensors at different levels on a logging tool are converted into an averaged signal representing the average bed signal at the center of the borehole at each of the different levels. A depth matching technique is applied to the averaged signals from the sensors at different levels on the logging tool to determine the optimum depth offset necessary for matching two sets of signals from sensors at the different levels of the logging tool.

Depth matching is performed on the two dimensional extremum curves to calculate an offset to match the two dimensional extremum curves. The calculated offset is then applied to the well log images to depth match them.

Abstract: Data slices of historical time series are leveraged to facilitate in more accurately predicting like data slices of future time series. Different predictive models are employed to detect outliers in different data slices to enhance the accuracy of the predictions. The data slices can be temporal and/or non-temporal attributes of a data set represented by the historical time series. In this manner, for example, a historical time series for a network location can be sliced temporally into one hour time periods as a function of a day, a week, a month, a year, etc. Outliers detected in these data slices can then be mitigated utilizing the predictive time series model by replacing the outlier with the expected value. The mitigated historical time series can then be employed in a predictive model to predict future web traffic for the network location (and advertising revenue values) with a substantial increase in accuracy.

Abstract: This invention provides directional connectivity described by the interconnections of the blocks in the schematic or netlist that are used to propagate impedance data from one block to another. The propagation of impedance data for discrete time based simulation programs allow for the simulation under less than ideal termination conditions between the blocks. This invention also supports functionality where the input impedance and output impedance of each block are not perfectly terminated. This assumption can lead to very significant modeling errors in the simulated results. In general, termination impedances are complex frequency dependent functions that result in frequency dependent mismatch losses between the blocks. This invention allows for the propagation and calculation of impedance mismatches between the various blocks.

Abstract: To perform a simulation, a design can be divided into “blocks” described by models. To ensure that data is efficiently transferred from an source model to a destination model, a dynamic first-in first-out (FIFO) can be placed between these models. The initial size of the dynamic FIFO can be set to a relatively small value. To prevent deadlock, the size of the FIFO can be automatically increased in size by increments. In this manner, the memory resources of the FIFO can be tightly controlled. Advantageously, the size of the optimized dynamic FIFO can be used as the desired size of the FIFO implemented in silicon, thereby also ensuring efficient use of silicon resources.
