Disclosed herein are rear suspension systems for bicycles that coupling the rear wheel of the bicycle to the bicycle frame through a swing arm assembly. The structures disclosed herein allow for independent movement of a swing arm assembly in both a vertical and horizontal directions.

Bicycle rear suspension with a two axis wheel path

A method for fabricating electroactive polymer transducers, the includes providing an electroactive polymer film comprising an elastomeric dielectric polymer, forming an array of electrodes on the film, and sandwiching the electrode array between a top and bottom array of frame components to form an array of electroactive polymer transducers.

Method of manufacturing electroactive polymer transducers for sensory feedback applications

The present invention provides optical systems, devices and methods which utilize one or more electroactive polymer actuators to provide shutter and/or aperture control.

Lens shutter and aperture control devices

Electroactive polymer transducers for sensory feedback applications are disclosed.

Electroactive polymer transducers for sensory feedback applications

Devices employing electroactive polymer actuators are disclosed. Acrylic dielectric material based actuators are optionally provided in which architectures are presented that allow for improved power output as compared with other known acrylic dielectric material based transducers. Such technology may be applied in motor-driven applications, lightweight flight applications and lighting applications among others.

Three-dimensional electroactive polymer actuated devices

The present invention provides optical systems, devices and methods which utilize one or more electroactive films to adjust an optical parameter of the optical device/system.

Optical systems employing compliant electroactive materials

Method for fabricating electroactive polymer transducer

Electroactive polymer transducers are disclosed. They are biased in a manner that provides for increased force and/or stroke output, thereby offering improved work potential and power output capacity. The biasing may offer additional or alternate functional advantage in terms of matching transducer performance with a given application such as a normally-closed valve. The improved biasing (including increased output biasing) may utilize negative spring rate biasing and/or a combination of negative or zero-rate biasing with positive rate biasing to achieve the desired ends.

Electroactive polymer transducers biased for optimal output

The present invention provides optical systems, devices and methods which utilize one or more electroactive polymer actuators to adjust an optical parameter of the optical device or system.

Optical lens displacement systems

Transducers employing electroactive polymer films are disclosed. Such transducers include an open frame and at least two layers extending within the frame, where the layers form a concave shape.

High-performance electroactive polymer transducers

The invention describes devices for controlling fluid flow, such as valves. The devices may include one or more electroactive polymer transducers with an electroactive polymer that deflects in response to an application of an electric field. The electroactive polymer may be in contact with a fluid where the deflection of the electroactive polymer may be used to change a characteristic of the fluid. Some of the characteristic of the fluid that may be changed include but are not limited to 1) a flow rate, 2) a flow direction, 3) a flow vorticity, 4) a flow momentum, 5) a flow mixing rate, 6) a flow turbulence rate, 7) a flow energy, 8) a flow thermodynamic property. The electroactive polymer may be a portion of a surface of a structure that is immersed in an external fluid flow, such as the surface of an airplane wing or the electroactive polymer may be a portion of a surface of a structure used in an internal flow, such as a bounding surface of a fluid conduit.

Electroactive polymer devices for controlling fluid flow

Electroactive polymer constructions that convert electrical energy to mechanical energy and vice versa are disclosed. The subject transducers (actuators, generators, sensors or combinations thereof) share the requirement of a frame or fixture element used in preloading elastomeric film electrodes and dielectric polymer in a desired configuration. The structures are either integrally biased in a push-pull arrangement or preloaded/biased by another element.
