A data entry system is provided using a virtual dynamic keypad having at least four keys, wherein to four of the keys at least substantially all of the letters of a language are distributively assigned and wherein the locations of the four letter keys relating to each other are dynamically defined during the entry of text. A text entry system is also provided using a virtual keypad having at least four keys wherein to four of its keys at least substantially all of the letters of a language are distributively assigned and wherein the locations of the four letter keys relating to each other are dynamically defined based on a calibrating procedure provided by the user. A data entry system is provided using a pointing device providing different pointing directions wherein each of the pointing directions duplicates a key of a predefined virtual keypad model wherein to at least some of its keys substantially all of the letters of a language are distributively assigned.

A fast and reliable technique for tuning multivariable model predictive controllers (MPCs) that accounts for performance and robustness is provided. Specifically, the technique automatically yields tuning weights for the MPC based on performance and robustness requirements. The tuning weights are parameters of closed-loop transfer functions which are directly linked to performance and robustness requirements. Automatically searching the tuning parameters in their proper ranges assures that the controller is optimal and robust. This technique will deliver the traditional requirements of stability, performance and robustness, while at the same time enabling users to design their closed-loop behavior in terms of the physical domain. The method permits the user to favor one measurement over another, or to use one actuator more than another.

The present invention relates to a method and a device for analyzing the accuracy of a fold (3) which is produced via a folding apparatus for printed products. In the process, with the printed products (1) being shingled, sensors (4) detect the position of the fold with respect to markings (5) which are printed onto the printed product, the folding accuracy and other quantities connected therewith being determined therefrom with the aid of computers.
