Abstract: In some embodiments, an actuation system includes a plurality of threaded member portions, a plurality of roller nuts, a driving member configured to receive mechanical energy from a power source, a plurality of driven members, and a magnetorheological (MR) fluid disposed between the plurality of driven members and at least one braking surface. An output member may be coupled between the rotor system and either the plurality of threaded member portions or the plurality of roller nuts and configured to translate linearly in response to the threaded member portions advancing or receding within the roller nuts.

Abstract: A magnetorheological fluid clutch apparatus comprises an input rotor adapted to be coupled to a power input, the input rotor having a first set of at least one input shear surface, and a second set of at least one output shear surface. An output rotor is rotatably mounted about the input rotor for rotating about a common axis with the input rotor, the output rotor having a first set of at least one output shear surface, and a second set of at least one output shear surface, the first sets of the input rotor and the output rotor separated by at least a first annular space and forming a first transmission set, the second sets of the input rotor and the output rotor separated by at least a second annular space and forming a second transmission set. Magnetorheological fluid is in each of the annular spaces, the MR fluid configured to generate a variable amount of torque transmission between the sets of input rotor and output rotor when subjected to a magnetic field.

Abstract: According to one embodiment, a trim actuator for a pilot input device includes a driven member and a driving member configured to receive mechanical energy from a power source. A magnetorheological (MR) fluid is disposed between the driving member and the driven member and configured to transmit a variable amount of mechanical energy from the driving member to the driven member such that the driven member moves in a first direction. An output member configured to be coupled between the driven member and the pilot input device. A spring is in mechanical communication with the output member and configured to apply a force in a second direction opposite of the first direction. A magnetic circuit is configured to control movement of the pilot input device by varying the strength of a magnetic field delivered towards the first MR fluid.

Abstract: The invention discloses a body cushioning pad, a body contact mat and a multi-layered cushioning structure composed of the body cushioning pad and the body contact mat. The cushioning pad consists of a plurality of foam blocks, each provided with an internal cavity having a predetermined size and shape to control the firmness of the block and means for maintaining the foam blocks as a unit. The body contact mat is a bi-dimensional latticed structure of spaced-apart studs made of a compressible material linked together by flexible linking elements. The multi-layered cushioning structure comprises both the cushioning pad and the body contact mat, and a wrapper to wrap the cushioning pad and the contact mat together.

Abstract: The present invention provides a shoe cover to adaptively fit over a shoe. The show cover has a sole, which includes at least two rigid bands of rigid material, disposed on the bottom of the sole and arranged in spaced relation to each other on opposite sides of a longitudinal axis of the sole, thereby rigidifying the sole. The sole also has an elastic band of the flexible material, spanning longitudinally between the two rigid bands from the front to the rear of the sole, thereby enabling lateral flexibility to adapt to a shoe. The present invention also provides a rigid L-shaped element, each including a first portion on the ground side, a second portion on the side wall, and a fulcrum joining them, to clamp an inserted shoe. A double injection method for producing the above is also provided.
