Title: Frank Kirchhoff: Innovator in Elevator Technology
Introduction
Frank Kirchhoff is a notable inventor based in Berlin, Germany. He has made significant contributions to the field of elevator technology, holding a total of 3 patents. His work focuses on enhancing safety and efficiency in elevator systems.
Latest Patents
One of Kirchhoff's latest patents is an elevator brake control system. This system is designed specifically for controlling an elevator brake in machine room-less elevators. It includes a drive machine that is coupled to an elevator car, allowing the car to move between various landings in a hoistway. The elevator brake has an engaged condition to hold the car in a fixed position and a released condition to allow movement. The control system features two safety devices that respond to failures in any elevator subsystem, ensuring the brake engages in case of such failures. Each safety device comprises a power semiconductor switching device.
Another significant patent is for a device and method for detecting misaligned or missing steps in conveyors. This missing step detector utilizes various sensors to monitor the drive speed of the conveyor and the presence of pallets or steps. By correlating sensor output signals to fixed values characteristic of the specific conveyor, the detector can effectively monitor for misaligned or missing steps, independent of conveyor speed and time.
