    摘要: Method for reducing instability and increasing computational efficiency in tomographic inversion for velocity model building. A system of tomographic equations is developed for a uniform grid. A non-uniform parameterization is found for which a linear mapping exists between the space of the uniform grid and the space of the non-uniform grid. The matrix that relates velocity to the tomographic data in the non-uniform representation is then given by the matrix product of the corresponding matrix in the uniform grid representation and the mapping matrix. Inversion can then be performed for the non-uniform parameterization on a smaller, more stable matrix.

    摘要: Method for building a subsurface model of velocity or other elastic property from seismic reflection data using tomography. The method uses velocity scans to pick a focusing velocity model at each image point (40). The focusing velocities are used to pick depth errors from tables (60) generated using a tomographic inversion matrix (30) and a suite of different velocity models (10). The depth errors are then reconstructed at each image point from the velocity scans based on the difference between the base velocity model and the most coherent velocity from the scan (70). The reconstructed depth errors are used to compute the velocity model update (80).

    摘要: A method and apparatus for hardware-based anamorphic video scaling. In one embodiment, the method includes the fetch of zero or more new input pixels according to an entry of an input control memory corresponding to a current output pixel. Once fetched, the zero or more new input pixels replace at least one stored input pixel of N, input pixels. Using the updated N, input pixels and an N, coefficient set selected according to an entry of a coefficient memory corresponding to the current output pixel, a pixel computation, such as, for example, an anamorphic scaling computation, is performed. In one embodiment, the anamorphic scaling is performed by subdividing an X×Y pixel frame into X/M M×Y pixel subframes. Other embodiments are described and claimed.

    摘要: An embodiment of the present invention is a technique to monitor on-die device power grid. A sensor circuit generates a ground reference (GR) signal and N power reference (PR) signals forming a ladder according to a programmable configuration. The GR signal tracks a device ground signal of a device and the PR signals track a device power signal of the device. A comparator circuit compares the GR signal with the N PR signals to provide N comparison output signals, the N comparison output signals indicating position and time that the GR reference signal moves across the ladder.

    摘要: The present invention includes a temperature-dependent power window and sunroof system for an automotive vehicle. This system according to the present invention is activated when the vehicle is presumably parked and left unattended by a vehicle operator. One aspect of the invention is directed to the detection of actions by the vehicle operator as input for system activation and deactivation, for example, the operator removes the ignition key, opens the driver door, closes the driver door and locks the door. Advantageously, if the vehicle operator stays in the vehicle after the key is removed from the ignition cylinder, the present invention remains inactivated whereby affording the maximum flexibility to the car driver. One preferred embodiment maintains a “comfortable” temperature range for the interior of the vehicle over the time period the vehicle is parked and left unattended. Moreover, to actively maintain the “comfortable” temperature range for the vehicle interior, a separate algorithm may be used. Another aspect of the invention includes means of communications to alert the vehicle operator and others in case of exceedingly high or low temperatures in the vehicle interior that might be life-threatening to those toddlers, pets or other incapacitated living beings who are left unattended in the vehicle.
