  • Patent number: 9988837
    Abstract: An operating system for a window covering includes at least one spring motor, at least one variable force brake, and at least one lift spool assembly operatively coupled to a panel for raising and lowering a panel. An effective shaft is operatively coupled to and synchronizes the spring motor, the variable force brake, and the lift spool. The variable force brake comprises a one-way clutch operatively coupled to the shaft. A brake member is operatively engaged with the one-way clutch to apply a brake force to the one-way clutch when the shaft is rotated. The magnitude of the brake force applied to the one-way clutch is determined by the rotational position of the shaft.

  • Patent number: 9920803
    Abstract: The invention relates to a disc-type brake which can use the energy of a transport machine during its traveling to brake, has a huge self-energizing action and is used for a motorcycle, a car, a truck, a train and an elevator. The brake has a very small control force (power), is simple and reliable and has a small volume. The brake is very easily designed as an electrically controlled disc-type brake system (EMB), the power and volume of an electrically controlled motor of the brake can be several times—more than a dozen of times less than that of an electrically controlled motor in the prior art, after its promotion, the brake can greatly improve the safety of the car and the motorcycle. The brake can reduce many parts, components and mechanisms and save much cost and bring us tremendous social and economic benefits and is a landmark brake.

  • Patent number: 9914529
    Abstract: A torque limited drive system comprising: an input shaft; at least one gear unit driven by the input shaft; a torque limiter having a torque limit and being driven by the at least one gear unit; and a torque limited output shaft driven by the torque limiter; wherein the torque limiter is adapted such that when it experiences a torque above its torque limit it applies a brake to said input shaft. The fact that the torque limiter is situated downstream of the gear units combined with the fact that the torque limiter brakes the input shaft upstream of the gear unit allows minimization of component weight within the gear units and within equipment driven by the output shaft due to the removal of the effect of efficiency and drag bandwidths associated with the gear units.

  • Patent number: 9863515
    Abstract: A self-locking actuator for moving a flight control surface of an aircraft and for self-locking in response to an external load applied to the actuator. The actuator includes a motor, a screw, and a drive gear that is rotatably driven by the motor to rotationally couple with the screw. A pawl support is coupled to and rotatable with the screw, and a swivel assembly is coupled to the pawl support for rotational movement with the screw and pivoting movement relative to the screw. The swivel assembly engages a cage that is fixed relative to the rotating screw, drive gear, and swivel assembly. Pivoting of the swivel assembly about a pivot axis engages the swivel assembly with the cage to positively lock with the cage and to prevent rotation of the screw in each of first and second opposite rotational directions of the screw about a rotational axis of the screw.
