  • Patent number: 10836605
    Abstract: An elevator car has at least one balustrade attached to a roof of the elevator car, which balustrade can be pivoted about a rotation axis between a folded-down position, in which the balustrade is arranged essentially horizontally, and a raised position, in which the balustrade is arranged essentially vertically. The balustrade is mechanically coupled to a 3-state switch, which switch can adopt three different switching states. The balustrade and the 3-state switch thus cooperate such that the 3-state switch adopts a first switching state when the balustrade is in the folded-down position, the 3-state switch adopts a second switching state when the balustrade is in the raised position, and the 3-state switch adopts a third switching state when the balustrade is in neither the folded-down position nor the raised position.

  • Patent number: 10837329
    Abstract: A fluid management system, or flow control system, for an automotive propulsion system is provided. The system includes a housing defining a sump configured to collect a volume of liquid and gaseous fluid and a pump configured to pump fluid from the sump. The pump defines a pump inlet and a pump outlet. A conduit is in fluid communication with the pump outlet. A passive valve is disposed within the conduit, the conduit defining a conduit outlet downstream of the passive valve, and the conduit further defining an orifice between the pump and the passive valve. The passive valve allows hydraulic fluid to flow past the valve, while substantially preventing air from flowing past the passive valve. The air is instead bled out through the orifice, along with some of the hydraulic fluid.

  • Patent number: 10822200
    Abstract: Elevator systems are described that include a traveling component movable along a guide rail and an overspeed safety system. The safety system includes a safety brake connected to an electromechanical actuator. A safety brake element of the safety brake is operable to engage with the guide rail to stop the traveling component. The electromechanical actuator includes a frame, a first magnetic element operably connected to the safety brake, a second magnetic element movably attached to the frame, and a third magnetic element fixedly attached to the frame. The second magnetic element is movable to urge the first magnetic element from a first position toward a second position.

  • Patent number: 10807846
    Abstract: A remotely adjustable automotive lift arm allows a user to position lift arms under the vehicle, extend them to the correct length, and position lifting pads to the correct location and height, all without requiring the user to bend over or kneel. The remotely adjustable automotive lift arm includes a telescopic arm, a screw jack assembly, a camera assembly, a gear assembly, and an input shaft. The telescopic arm includes two tubes with one being telescopically engaged to the other. The screw jack assembly is used to adjust the lifting pad height to achieve a level lift of a vehicle prior to the vehicle being lifted off the ground. The camera assembly provides a live image of the vehicle's undercarriage in order to precisely position the screw jack assembly. The input shaft can receive an input torque than can be transferred to the screw jack assembly by the gear assembly.
