  • Patent number: 10807731
    Abstract: A motor mount assembly is provided for coupling a propeller motor to a body of an unmanned aerial vehicle (UAV). The motor mount assembly includes a floating portion and acts to attenuate frequencies of vibration from the propeller motor during operation, which modifies the corresponding noise that is produced and reduces stresses on the various components. The floating portion is surrounded on all sides by isolation portions (e.g., made of elastomers or other materials) that are held within a casing that attaches to the body of the UAV. In one implementation, the motor mount assembly is modular such that one or more of the isolation portions may be replaced with different isolation portions (e.g., having different attenuation properties), depending on the direction and nature of the vibrations from the propeller motor that are to be attenuated for a particular application.

    Abstract: A method of manufacturing a fuel cell stack includes compressing a stack of bipolar plates with a variable applied load a feature non-deformed displacement distance, which is measured from an initial height of the stack of bipolar plates. A first applied load at a first displacement distance and a second applied load at a second displacement distance are sensed. The first displacement distance and the second displacement distance are each less than the feature non-deformed displacement distance. A best fit curve, passing through the first applied load at the first displacement distance and the second applied load at the second displacement distance, is then determined. A final displacement distance, measured from the initial height, is calculated from the best fit curve for a target applied load. The stack of bipolar plates is then compressed to the final displacement distance measured from the initial height.

  • Patent number: 10421346
    Abstract: An antivibration device capable of restraining a stopper rubber from being turned up when a connecting member is inserted between a first attached member and a displacement restriction member. A stopper rubber is mounted on a surface of a connecting member opposite to a first attached member and includes a mounted portion brought into abutment on a displacement restriction member when the connecting member is displaced in a rebound direction, and a hook portion formed at the outer edge of the mounted portion. The connecting member includes an engaged portion (protrusion) engaged with the hook portion. Thus, when the connecting member is inserted between the first attached member and the displacement restriction member, the stopper rubber (the mounted portion) can be restrained from being turned up.
