Abstract: An elevator system is provided which includes a plurality of hoistway doors, a corresponding plurality of sets of non-contact switches, each set arranged to detect when a respective hoistway door is open, and a monitoring device. Each set of non-contact switches comprises a first non-contact switch arranged to open when the respective hoistway door is open and a second non-contact switch arranged to open when the respective hoistway door is open. The first non-contact switches of the plurality of sets are connected in series to form a first electrical path and the second non-contact switches of the plurality of sets are connected in series to form a second electrical path. The monitoring device is arranged to measure an electrical property of the first electrical path and an electrical property of the second electrical path to detect when a hoistway door is open.

Abstract: 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).

Abstract: An elevator safety system (20) for an elevator system (2) with a self-diagnostic functionality includes at least two safety channels (22a, 22b), wherein each safety channel (22a, 22b) is configured for supplying a safety signal (23a, 23b) in case a safety issue has been detected. The elevator safety system (20) comprises a self-diagnostic evaluator (24), which is configured for receiving any safety signals (23a, 23b) supplied via the safety channels (22a, 22b); starting a timer (25) for measuring a predetermined period of time in case a safety signal (23a, 23b) is supplied on one of the safety channels (22a, 22b); and stopping any further operation of the elevator system (2) in case the received signal (23a, 23b) is still supplied after the predetermined period of time has expired.

Abstract: An elevator system (2) comprises a hoistway (4) extending between a plurality of landings (8a, 8b, 8c); an elevator car (60) configured for moving in two opposite directions along the hoistway (4); and an elevator safety system (1). The elevator safety system (1) comprises at least one safety gear (20) configured for moving along the hoistway (4) and, upon activation, braking movement the elevator car (60); at least one mobile safety node (43, 45) configured for moving along the hoistway (4) with the at least one safety gear (20) and for controlling the at least one safety gear (20); and at least one stationary safety node (42, 44). The elevator safety system (1) further comprises a communication bus (17) connecting the safety nodes (42-45) with each other and allowing the safety nodes (42-45) to communicate with each other.

Abstract: An elevator system includes a primary source of electrical power; a power unit having a power supply, the power supply producing DC power from the primary source of electrical power. A rescue storage device provides power to the elevator system when the primary source of electrical power is unavailable. The rescue storage device is coupled to an output of the power supply to provide additional DC power with the DC power when the primary source of electrical power is available and an increased power requirement is present.
