Title: Innovations in Elevator Technology by Claudia M Schmidt-Milkau
Introduction
Claudia M Schmidt-Milkau is a distinguished inventor based in Berlin, Germany, renowned for her contributions to the field of elevator technology. With two patents to her name, her work focuses on advancing the functionality and safety of elevator systems.
Latest Patents
Claudia's latest innovations include a method for measuring elevator hoistway position using audible signals. This involves the installation of a microphone in the ceiling of the elevator hoistway and a loudspeaker at the top of the elevator car. By emitting a 9-16 kHz up-sweep from the loudspeaker, the travel time of the sound signal is determined through a cross-correlation with a quiet reference signal. This allows for precise calculations of the distance between the microphone and loudspeaker, factoring in the hoistway temperature for accurate absolute position determination.
Additionally, Claudia has developed a system for measuring elevator car position using ultrasound. This technology employs two ultrasonic transducers positioned in the hoistway and on the elevator car to measure the time taken for an ultrasonic signal to travel between them and return. This innovation significantly enhances the accuracy of elevator positioning systems.
