Title: The Innovative Contributions of Claus Ruther in Elevator Technology

Introduction

Claus Ruther, hailing from Munich, Germany, is a notable inventor recognized for his significant contributions to elevator technology. With a focus on enhancing motor control mechanisms, his work has implications for improving elevator efficiency and safety.

Latest Patents

Ruther holds one patent titled "High Frequency Pulse Width Modulation." This innovation involves a counter that increments multiple times during the duty cycle of a microprocessor. A comparator connected to both outputs generates a High signal when the microprocessor output exceeds the counter output and a Low signal when the counter output meets or exceeds the microprocessor output. This system allows the microprocessor output, which is proportional to the desired motor speed for an elevator door drive motor, to follow a velocity profile stored in a ROM. Consequently, the High:Low ratio of the comparator output produces a pulse width modulation signal, amplified for the motor at a much higher frequency than the microprocessor duty cycle.
