Title: Wilfried Rohde: Innovator in Multifunction Printing and Control Systems
Introduction
Wilfried Rohde is a notable inventor based in Unterkirnach, Germany. He has made significant contributions to the fields of multifunction printing and control systems. With a total of 2 patents, his work reflects a commitment to innovation and technological advancement.
Latest Patents
One of Rohde's latest patents is for a multifunction printer equipped with a journal device. This device is designed for recording data processed in the printer for purposes of data securing and documentation. The printer includes at least one print unit for printing input data, along with additional printer modules tailored to specific functions. To address space requirements, the journal device is coordinated with a form print unit or an additional sales-receipt print unit. This innovative design features a secondary controller, an interface, and a data storage memory, allowing for permanent filing and recall of input data.
Another significant patent involves a method and circuitry for automatically adjusting variable-gain amplification. In this invention, a sinusoidal signal critical for the control loop is superimposed over a positioning parameter. The system utilizes synchronous rectifiers to filter out oscillation components, which are then compared in a comparator. The control and regulating circuit adjusts the variable-gain amplification until the amplitudes of the oscillation components are equal, ensuring optimal performance. This technology can even be adjusted in a compact-disc player while it is in operation.
