Patent number: 11623841Abstract: An elevator safety system comprises a plurality of door safety units, each door safety unit; a communication bus connecting the plurality of door safety units; a control unit connected to the communication bus for allowing communication between the plurality of door safety units and the control unit; and at least one position sensor configured for providing information about the current position of an elevator car within a hoistway. Each door safety unit is assigned to an elevator hoistway door and configured for monitoring a condition of the assigned elevator hoistway door. The control unit is configured for polling door safety units included in a subset S1, S2) of the door safety units which are located within a predetermined distance (D1, D2) from the current position of the elevator car.Type: GrantFiled: November 14, 2018Date of Patent: April 11, 2023Assignee: OTIS ELEVATOR COMPANYInventors: Andreas Tutat, Helge Krambeck

Patent number: 11267677Abstract: Elevator systems and methods are provided. The systems include a traveling component movable along a guide rail within an elevator shaft, an elevator machine operably connected to the traveling component and including a machine brake, and an overspeed safety system. The overspeed safety system includes a safety brake and an electromechanical actuator, the brake engageable with the guide rail. A safety system controller operably connects to the electromechanical actuator and triggers the electromechanical actuator due to at least a detected triggering event. A temporary power supply is operably connected to the overspeed safety system to provide power in the event of a power failure.Type: GrantFiled: August 27, 2019Date of Patent: March 8, 2022Assignee: OTIS ELEVATOR COMPANYInventors: Jan Ruhnke, Helge Krambeck

Publication number: 20210276823Abstract: An safety system (40) including: a plurality of landing door sensors (26), each landing door sensor (26) being configured to provide a warning signal (52) when a respective landing door (22) is open; at least one position sensor (14) configured to determine a current position (54) of an elevator car (10) moving within a hoistway (2); an elevator brake (7) configured to halt the motion of the elevator car (10); and a controller (8) configured to send an emergency stop signal (58) to the elevator brake (7). The controller (8) is configured to determine whether to send the emergency stop signal (58) based on: a direction of travel of the elevator car (10) with respect to the open landing door (22); a current speed of the elevator car (10); and a distance (D) between the open landing door (22) and the current position of the elevator car (10).Type: ApplicationFiled: November 19, 2020Publication date: September 9, 2021Inventors: Helge Krambeck, Peter Herkel

Patent number: 11090154Abstract: A holding device for a suture ring is provided. The holding device may include a retainer in which a suture ring can be releasably fixed, in particular clamped, and a handle which is connected to the retainer and which has an actuating mechanism for fixing and/or releasing a connection between the retainer and the suture ring. By means of the holding device, a suture ring can be fixed in the retainer such that a tubular part and/or object can be pushed into the suture ring without exerting forces on the tissue to which the suture ring is connected.Type: GrantFiled: May 9, 2017Date of Patent: August 17, 2021Assignee: BERLIN HEART GMBHInventors: Helge Krambeck, Gerhard Lauterbach, Felix Von Winterfeld
