摘要： A power delivery system for a microprocessor or other ASIC. The power delivery system includes a plurality of cascaded buck stages connected in series, wherein a last buck stage in the plurality of cascaded buck stages provides an output voltage Vo in response to an input voltage Vin applied to a first buck stage of the plurality of cascaded stages. A duty cycle control regulates a duty cycle of each buck stage to maintain the output voltage Vo. The duty cycle control sets the duty cycle of the first buck stage of the plurality of cascaded buck stages to 1 if an input-to-output voltage ratio (Vin/Vo) is lower than a threshold input-to-output voltage ratio RT.

摘要： A supply assembly for an LED lighting module includes a control switch for supplying a constant current to the LED lighting module. A dual switching signal composed of low frequency bursts of high frequency pulses is applied to the control switch. By varying the low frequency component of the dual switching signal, the average current through the LED lighting module may be varied in order to vary the light intensity outputted by the LED lighting module.

摘要： Method for generating a new family of seismic attributes sensitive to seismic texture that can be used for classification and grouping of seismic data into seismically similar regions. A 2D or 3D data analysis window size is selected (23), and for each of multiple positions (25) of the analysis window in the seismic data volume, the data within the window are transformed to a wavenumber domain spectrum (26). At least one attribute of the seismic data is then defined based on one or more spectral properties, and the attribute is computed (28) for each window, generating a multidimensional spectral attribute data volume (29). The attribute data volume can be used for inferring hydrocarbon potential, preferably after classifying the data volume cells based on the computed attribute, partitioning the cells into regions based on the classification, and prioritizing of the regions within a classification.
