Latest Patents
One of Prebola's latest patents is titled "Dynamic S Curve Stepper Motor Profile." This innovative technique enhances the performance of stepper motors by implementing dynamic velocity profiles for controlling the motion of a mass. The method involves accelerating the moving mass according to a specific velocity profile, detecting its position, and adjusting the velocity profile based on this detection. This adjustment includes reducing the maximum velocity if the mass reaches the specified position before achieving the maximum velocity.
Another notable patent is "Automatic Background Control for an Electrostatic Copier." This invention features a document background control system that utilizes a sensor in the optical path of a reproduction machine. The sensor detects the background of a document during the scanning process and adjusts the illumination accordingly. Additionally, it includes a control mechanism to modify the charging potential on the photoconductor in response to non-white document backgrounds.
