A system that facilitates estimating functional relationships associated with one or more columns in a database comprises a sampling component that receives a random sample of records within the database. An estimate generator component calculates an estimate of strength of functional relationships based at least in part upon the received samples. For example, the estimate generator component can calculate an estimate of strength of a column as a key column based at least in part upon the received samples.

A method for modeling bond wires in an IC package for predicting noise effects generated by electromagnetic coupling in complex bond wire configurations. A look-up table of equivalent LC circuit models for the bond wires is generated that accurately predicts the effects of the bond wire circuitry of a signal transmission system. Switch and mirror techniques are applied to reduce the bond wire configurations necessary to simulate. The method includes: setting parameters related to the IC package layout of groups of bond wires; sub-dividing each group of bond wires into regions, each including a portion of the bond wire or its corresponding pad, and generating dissection planes for the regions consisting of the bond wires; performing a 3D simulation on the regions consisting of the corresponding pads, and a 2D simulation for each dissection plane; constructing equivalent circuit models for groups of bond wires and corresponding pads based on the 3D and 2D simulations results; inputting the equivalent circuit models into a circuit simulator to measure the noise effects; and modifying the layout geometry to meet noise targets.

A first variable delay circuit delays an input signal, introduces a first delay into a first edge of the input signal, and generates a first delay signal. A second variable delay circuit delays the input signal, introduces a second delay into a second edge, and generates a second delay signal. A control circuit controls the first variable delay circuit and the second variable delay circuit such that the first delay and the second delay are identical. A generation circuit combines the first edge of the first delay signal and the second edge of the second delay signal, and generates a third delay signal.

A display calibration system includes: a display section subject to calibration; a correction data outputting section configured to perform a calibration process to determine, for each of the pixels of the display section, correction data for non-uniformity correction; and a first storage section configured to store reference data to be used in the calibration process. The reference data represents, for individual color patches of a first predetermined number, correspondences between RGB values and reference values. The correction data outputting section obtains, on a basis of the reference data and the measurement values of the color patches of a second predetermined number that is less than the first predetermined number, the pieces of correction data with respect to RGB values of the individual color patches of the predetermined second number. With this arrangement, it is possible to shorten a processing time of the calibration process.

An analog floating gate circuit (10-3, 10-4) includes a first sense transistor (21, 3), a first storage capacitor (20, 5), and first (24, 4) and second (31A, 42) tunneling regions. Various portions of a first floating gate conductor (12, 2) form a floating gate of the first sense transistor, a floating first plate of the first storage capacitor (20, 5), a floating first plate of the first tunneling region, and a floating first plate of the second tunneling region, respectively. A second plate of the first storage capacitor is coupled to a first reference voltage (VREF, GND), and a second plate of the second tunneling region is coupled to a second reference voltage (VPROG / GND). Compensation circuitry (44-1, 44-2) is coupled to the first floating gate conductor, for compensating loss of trapped charge from the first floating gate conductor.
