A process for depositing an active substance on selected regions of the surface of a stent, comprising: providing the active substance in at least one form selected from the group consisting of a powder and a paste; and depositing the active substance on the selected regions of the surface of the stent. In generating the extended reference signal, the CS is determined as a function for both a basic CS parameter and an extended CS parameter. Power, signal processing, and communications electronics may be built into the sleeve and control data may be transmitted wirelessly to the controlled machine or robotic device. The control signal pins connect to the third bus. The rolling member connection belt is formed from a metal plate member having a corrugated-shape, in section in a longitudinal direction thereof, formed at least to one portion thereof or entire portion thereof in the longitudinal direction, and the corrugated-shape has peak and valley portions each extending in a direction normal to the longitudinal direction of the metal plate member. A scrambler or descrambler pattern is computed according to the polynomial matrix, and input data is bitwise exclusive-ORed with the computed scrambler or descrambler pattern to generate scrambled or descrambled output data.
