Latest Patents

Lutz Vietze holds a patent for a groundbreaking invention titled "Measuring elevator hoistway position using audible signals." This patent involves a system where a microphone is installed on the ceiling of an elevator hoistway, and a loudspeaker is placed on top of the elevator car. The system utilizes a 9-16 kHz up-sweep sound signal transmitted from the loudspeaker to the microphone. By cross-correlating the received sound signal with a reference signal, the travel time of the sound is calculated. This information is then used to determine the distance between the microphone and the loudspeaker, allowing for accurate positioning of the elevator car. Additionally, the hoistway temperature is measured and factored into the absolute position calculation.
