An exemplary elongated elevator load bearing member includes a plurality of tension elements that extend along a length of the load bearing member. A plurality of weave fibers transverse to the tension elements are woven with the tension elements such that the weave fibers maintain a desired spacing and alignment of the tension elements relative to each other. The weave fibers at least partially cover the tension elements. The weave fibers are exposed and establish an exterior, traction surface of the load bearing member.

Elevator suspension and/or driving assembly having at least one traction surface comprising exposed weave fibers

Elevator coated ropes or belts are disclosed. The coated rope or belt may include at least one cord and a jacket retaining the at least one cord. The cord may include a plurality of filaments. The filaments are free of second-order helical structure. In a first embodiment, the filaments includes at least one inner filament and a plurality of outer filaments surrounding the at least one inner filament. The outer filaments are bunched together by forming a first-order helical structure through the length of the cord. In a second general embodiment, the filaments are free of both first- and second-order helical structures. The filaments are bunched together by a restraining loop or adhesive at one or more locations along the length of the cord. Methods of making the tension cord are also disclosed.

Coated rope or belt for elevator systems

An Environmental Control System (ECS) is disclosed for providing conditioned air to a conditioned air space. The ECS includes one or more first modules, each with a turbofan engine or Auxiliary Power Un it (APU), a first heat exchanger, a first turbine, a first water collector, and a first auxiliary fan powered by the first turbine. The ECS also includes one or more second modules. Each second module includes a mixing manifold, a second heat exchanger, an optional second water collector, and a second auxiliary fan powered by a second turbine.

Modular environmental air conditioning system

A feedback system for a motor of an elevator system is provided. The feedback system may include a first sensor and a processing circuit. The first sensor may be disposed in proximity to a drive component of the elevator system and configured to detect a change in position of the drive component. The processing circuit may be configured to receive a first data signal from the first sensor corresponding to the change in position of the drive component and generate a feedback signal for controlling the motor based on the first data signal.

Position feedback for elevator system

A humidity control system including a heat pump with desiccant coated passive heat transfer devices on both sides of the heat pump and an air circulation system for alternately directing a process air stream to be humidity controlled and a separate regenerative air stream past each side. As desiccant on one side becomes laden with moisture, the air streams are redirected to the opposite sides of the heat pump so the regenerative stream can remove moisture from the first side. Simultaneously, the air stream to be humidity controlled uses the previously regenerated desiccant on the second side.

Heat pump enabled desiccant dehumidification system

A system for the management of thermal transfer in a gas turbine engine includes a heat generating sub-system in operable communication with the engine, a fuel source to supply a fuel, a fuel stabilization unit to receive the fuel from the fuel source and to provide the fuel to the engine, and a heat exchanger in thermal communication with the fuel to transfer heat from the heat generating sub-system to the fuel. A method of managing thermal transfer in an aircraft includes removing oxygen from a stream of a fuel fed to an engine used to drive the aircraft, transferring heat from a heat generating sub-system of the aircraft to the fuel, and combusting the fuel. A system for the thermal management of an aircraft provides for powering the aircraft, supplying a fuel deoxygenating the fuel, and transferring heat between a heat generating sub-system of the aircraft and the fuel.
