Patent number: 10005641Abstract: A vibration dampening device is operable to dampen vibrations within ropes of an elevator car or other components to improve ride quality, and is further operable to harness or harvest and convert energy from those vibrations into electrical energy. The dampening device includes a macro-fiber composite and the vibrations are communicated or transmitted to the macro-fiber composite. The macro-fiber composite is operable to harness or harvest and convert energy from vibrations into electrical energy. Such electrical energy is communicated or transmitted to a control system of the elevator car for storage and/or use.Type: GrantFiled: June 16, 2015Date of Patent: June 26, 2018Assignee: ThyssenKrupp Elevator CorporationInventor: Rory S.

Patent number: 8276715Abstract: A method for assigning an elevator car to respond to a call signal includes a controller that determines which elevator car will respond to the call signal based on certain time metrics. The controller receives a hall call signal, and based on certain time metrics that can include, e.g., an estimated wait time (EWT), and/or estimated travel time (ETT), assigns the call signal to an elevator car. In this example, EWT represents the time a passenger is waiting for an elevator car to arrive, and ETT represents the it takes for a passenger to reach their destination once having boarded an elevator car. In some versions, an estimated time to destination (ETD) is used in determining which elevator car to assign, where ETD represents the sum of EWT and ETT. In some versions, a handling capacity coefficient (HCx), which reflects current traffic conditions, is used in determining which elevator car to assign.Type: GrantFiled: December 27, 2011Date of Patent: October 2, 2012Assignee: ThyssenKrupp Elevator Capital CorporationInventors: Rory S.

Patent number: 8162110Abstract: An apparatus for automatically equalizing the uneven tension between ropes of an elevator in combination with a load cell to determine elevator load. The load of an elevator car having multiple tension members is automatically balanced while load is measured using a single load cell. The incorporation of a load cell with an autobalancing system allows for an accurate measure of an elevator load to be taken while providing the benefits of having uniform rope lengths in the elevator system. The apparatus may have various arrangements, including an in-line configuration and a grouped configuration. The apparatus may also dampen the vibration energy that is usually imparted to an elevator car.Type: GrantFiled: June 19, 2009Date of Patent: April 24, 2012Assignee: ThyssenKrupp Elevator Capital CorporationInventors: Rory S. Smith, Alan M. Parker, Chi Phan

Patent number: 8123002Abstract: A system and method for minimizing compensation rope sway by altering the natural frequency of compensation ropes using servo actuators. The rope sway may be minimized by moving the compensation sheave to adjust the tension of the compensation rope or adjusting the position of the termination of a compensation rope to account for changes in the position of a structure. Servo actuators may also be used to re-level the elevator car to account for rope stretch.Type: GrantFiled: September 15, 2008Date of Patent: February 28, 2012Assignee: Thyssenkrupp Elevator Capital CorporationInventors: Rory S.

Patent number: 8096024Abstract: Disclosed is a termination device for an aramid-based elevator rope having a high breaking strength. The termination device comprises a socket having a cylindrical, tapered internal passageway adapted to receive a corresponding wedge. The wedge includes a semi-cylindrical passageway in a substantially helical configuration to increase the surface area between the associated rope and the wedge. The termination device clamps the length of rope between tapered portions of the socket and the semi-cylindrical passageway of the wedge with a substantially uniform application of force on the cross-section of the rope.Type: GrantFiled: August 13, 2008Date of Patent: January 17, 2012Assignee: Thyssenkrupp Elevator Capital CorporationInventors: Rory S.

Patent number: 7967113Abstract: The invention provides a system and method for handling power outages in a multiple car elevator system in a building having a plurality of floors. The system includes an energy calculator connected to the elevators, and determines a total energy of the elevator system, a total energy required to handle a power outage, a plan to prepare for a power outage and a plan to handle a power outage. The system also includes a movement controller connected to the elevator(s) and the energy calculator. The movement controller receives the plan to prepare and the plan to handle from the energy calculator, and the movement controller executes the plan to prepare if there is no power outage and the movement controller executes the plan to handle if there is a power outage.Type: GrantFiled: April 28, 2009Date of Patent: June 28, 2011Assignee: Thyssenkrupp Elevator Capital CorporationInventors: Rory S.
