Title: The Innovations of Hans Kern
Introduction
Hans Kern is a notable inventor based in Munich, Germany. He has made significant contributions to the field of technology, particularly in the area of printing mechanisms and motor control systems. With a total of 8 patents to his name, Kern's work has had a lasting impact on various industries.
Latest Patents
One of his latest patents is a microprocessor-controlled printing mechanism that incorporates an opto-electronic sensor. This innovative system senses the movement of a vane fixed to the armature of the print mechanism. The output signal generated by the sensor is used to define periods for measuring the speed of the armature's movement. A microprocessor supplies accelerating and decelerating pulses to the armature magnet, allowing it to achieve a preselected printing force. This technology ensures that the armature returns to its rest position rapidly without rebound.
Another significant patent by Kern is a speed control circuit for a DC motor. This circuit features a phase comparator that receives a theoretical frequency from a clock pulse generator and an actual frequency from a pulse transmitter connected to the motor's drive shaft. The system combines rotation direction signals in a logic element, which then drives the DC motor. The reference voltage supplied to the drive circuit is proportional to the phase deviation detected by the comparator, allowing for precise control of the motor's current.
