Application No.	Application Title	Issue Date
20080109503	Sine wave generator with dual port look-up table An automatic test system that includes low cost and accurate circuitry for generating sinusoidal signals. Each sinusoidal signal generator includes a look-up table that can, for each phase on sine wave, output two digital values representing an in-phase and a quadrature...	05/08/2008
20080109504	Low cost, high purity sign wave generator An automatic test system that includes low cost and accurate circuitry for generating sinusoidal signals. Each sinusoidal signal generator produces a series of digital values approximating a sine wave. These values are computed, avoiding the need for large memories to s...	05/08/2008
20080005212	METHOD AND APPARATUS FOR INTERACTIVE CURVE GENERATION A system of curve generation takes a sequence of control points and constraint codes for each control point, and outputs a curve in which each of the constraints is satisfied. The set of constraints is chosen from the tangent angle, curvature, first derivative of curvat...	01/03/2008
