    Abstract: A lens driving device, comprises a base; a casing fixed to the base; a coil bracket disposed within the casing; a coil wound on the coil bracket, a spring disposed within the casing, a drive rod; and a lens holder; wherein, one end of the spring is fixed to the base; one end of the drive rod is fixed to the other end of the spring, and the other end of the drive rod extends out of the casing. The lens holder is slidably fixed to the exposed portion of the drive rod. The lens holder is held stationary with respect to the drive rod by static friction between the drive rod and the lens holder. A driving signal may be applied to the coil to move the lens holder. The driving signal has the characteristic of making the current flowing through the coil slowly increase and then rapidly decrease, or to rapidly increase and then slowly decrease. The drive current is preferably a sawtooth pulse train, with each pulse causing movement of the lens holder in the micron range or below.

    Abstract: A method of simulating operation of a VLSI interconnect structure having capacitive and inductive coupling between nodes thereof. A matrix X and a matrix Y containing different combinations of passive circuit element values for the interconnect structure are obtained where the element values for each matrix include inductance L and inverse capacitance P. An adjacency matrix A associated with the interconnect structure is obtained. Numerical integration is used to solve first and second equations, each including as a factor the product of the inverse matrix X1 and at least one other matrix, with first equation including X1Y, X1A, and X1P, and the second equation including X1A and X1P.

    Abstract: Embodiments of the invention disclose a method for K-only (gray/black) object rendering in a high-speed color controller of a printing system. The method includes setting a flag to indicate selection of a K-only text and barcode print preference from a user of a print system, receiving one or more objects to be printed by the print system, the one or more objects including at least one of a text object and a barcode object, determining whether an input color space for the at least one text object and barcode object should be converted to K-only black ink, and rendering the at least one of the text object and the barcode object as K-only black ink if the input color space is determined to be converted to K-only black ink.
