Abstract: An electronic safety actuation device for braking an elevator car includes a safety brake movable between a non-braking position and a braking position, a first electronic safety actuator operably coupled to the safety brake via a first link member, and a second electronic safety actuator operably coupled to the safety brake via a second link member. Operation of the first electronic safety actuator applies a force to the first link member to move the safety brake from the non-braking position to the braking position. Operation of the second electronic safety actuator applies a force to the second link member to move the safety brake from the non-braking position to the braking position.

Abstract: A system includes a memory system and a processor of a first processing system including a processor core, a direct memory access controller, and a communication interface. The processor core is configured to execute a plurality of instructions to configure the direct memory access controller to trigger a transmitter interrupt upon transmitting a first synchronization message through the communication interface to a second processing system, configure the direct memory access controller to trigger a receiver interrupt upon receiving a second synchronization message from the second processing system, determine a time difference between triggering of the transmitter interrupt and the receiver interrupt, and adjust a synchronization skew of a real-time scheduler based on the time difference to tune real-time synchronization between the first processing system and the second processing system.

Abstract: An elevator system is provided and includes at least one guide rail, safeties to respectively selectively impede or permit movement of an elevator car along a corresponding guide rail and first and second electronic safety actuators (ESAs) respectively coupled to a corresponding safety. The first ESA includes a first braking surface located a first distance from the corresponding guide rail, the second ESA includes a second braking surface located a second distance from the corresponding guide rail and the first and second braking surfaces are deployable across the first and second distances, respectively, to contact the corresponding guide rails. The elevator system further includes a sensing system to determine the first and second distances and a control system to deploy the first and second braking surfaces toward the corresponding guide rails in response to an over-speed or an over-acceleration condition with synchronization based on the first and second distances.

Abstract: An illustrative example embodiment of a device for controlling movement of an elevator car includes an emergency stopping supervisor, such as a processor and memory associated with the processor. The emergency stopping supervisor is configured to: determine when an indication from an electrical protection device indicates that the elevator car should be stopped, issue a command for the elevator car to move at a reduced speed, monitor continued movement of the elevator car at the reduced speed, and continue to allow the elevator car to move at the reduced speed until a selected condition exists or immediately cause the elevator car to stop if the reduced speed is not within a predetermined range.

Abstract: A vertical bounce detection system of an elevator system includes at least one sensor operable to detect vertical movement of an elevator car in a hoistway. The vertical bounce detection system also includes a processing system communicatively coupled to the at least one sensor and a memory system having instructions stored thereon that, when executed by the processing system, cause the vertical bounce detection system to determine a bounce energy level of the elevator car based on sensor data from the at least one sensor. The instructions further cause the vertical bounce detection system to compare the bounce energy level to a bounce condition threshold. A speed reduction of the elevator car is commanded to continue movement of the elevator car at a reduced speed based on determining that the bounce energy level exceeds the bounce condition threshold.
