Abstract: A bicycle can include a frame. The frame can include a front steering axle, a front fork assembly, and a handlebar assembly for steering a front wheel of the bicycle. The bicycle can also include one or more vibration isolators. The one or more vibration isolators can be operatively connected to at least one of the frame, the front steering axle, the front fork assembly, and the handlebar assembly. The one or more vibration isolators can also be configured to exhibit a non-linear stiffness profile including a region of quasi-zero stiffness. As a result, the one or more vibration isolators isolate a rider of the bicycle from vibrations transferred through the frame.

Abstract: A rotating machine system include a rotating machine. The rotating machine system can include a housing. The housing can include an inner surface. The housing can surround at least a portion of the rotating machine. The inner surface of the housing can be spaced from the rotating machine such that a space is defined therebetween. The rotating machine system can include a plurality of vibration isolators. The vibration isolators can be positioned in the space and can be operatively connected to the rotating machine and to the inner surface of the housing. The vibration isolators can be compression-type vibration isolators.

Abstract: Systems and methods relate to a manner of improving an actuator used to hold an object. In one embodiment, an actuator includes a body that is bi-stable with a coiled state and an uncoiled state. The actuator also includes a strip, coupled to the body, that coils the body according to a power source that activates in response to a detected proximity of an object. The actuator also includes a wire coupled to a side of the body opposite from the strip and the wire uncoils the body in response to heat caused by the power source.

Abstract: A vehicle seat can be configured to provide support to a vehicle occupant in conditions when lateral acceleration is experienced. Shape memory material members can be operatively positioned with respect to a seat portion of the vehicle seat. The shape memory material members can be selectively activated by an activation input. When activated, the shape memory material members can engage a seat pan so as to cause the seat pan to tilt in a respective lateral direction. As a result, a seat cushion supported by the seat pan can also tilt in the respective lateral direction. The seat cushion can be tilted in a lateral direction that is opposite to the direction of the lateral acceleration. Thus, the effects of lateral acceleration felt by a seat occupant can be reduced. The shape memory material members can be selectively activated based on vehicle speed, steering angle, and/or lateral acceleration.

Abstract: A multi-stable actuator includes a first superelastic-shape memory alloy (SE-SMA) wire extending between a first fixed support and a movable element and a second SE-SMA wire extending between a second fixed support and the movable element. The first SE-SMA wire is in tension against the second SE-SMA wire and the second SE-SMA wire is in tension against the first SE-SMA wire. The multi-stable actuator also includes at least one heating device configured to heat the first SE-SMA wire independent of the second SE-SMA wire and to heat the second SE-SMA wire independent of the first SE-SMA wire such that the movable element moves between and to at least three fixed positions without use of a brake or clutch.
