摘要： A dynamic interface between a vehicle windshield and a structure (e.g., an A-pillar) is provided. The dynamic interface can be actively managed to allow its configuration to be selectively changed based on real-time driving environment conditions. The interface can include one or more actuators that can be selectively activated or deactivated to change the aerodynamic characteristics of the interface. When a crosswind activation condition is detected, the actuator(s) can be activated. The actuator(s) can be soft-bodied structures. The actuator(s) can include a bladder defining a fluid chamber filled with a dielectric fluid. A first conductor and a second conductor can be operatively positioned on opposite portions of the bladder. When electrical energy is supplied to the conductors, they can become oppositely charged. As a result, the conductors can be electrostatically attracted toward each other, displacing some of the dielectric fluid to an outer peripheral region of the fluid chamber.

摘要： An electro-hydraulic actuator includes a deformable shell defining an enclosed internal cavity and containing a liquid dielectric, first and second electrodes on first and second sides, respectively, of the enclosed internal cavity. An electrostatic force between the first and second electrodes upon application of a voltage to one of the electrodes draws the electrodes towards each other to displace the liquid dielectric within the enclosed internal cavity. The shell includes active and inactive areas such that the electrostatic forces between the first and second electrodes displaces the liquid dielectric within the enclosed internal cavity from the active area of the shell to the inactive area of the shell. The first and second electrodes, the deformable shell, and the liquid dielectric cooperate to form a self-healing capacitor, and the liquid dielectric is configured for automatically filling breaches in the liquid dielectric resulting from dielectric breakdown.

摘要： High strain hydraulically amplified self-healing electrostatic transducers having increased maximum theoretical and practical strains are disclosed. In particular, the actuators include electrode configurations having a zipping front created by the attraction of the electrodes that is configured orthogonally to a strain axis along which the actuators. This configuration produces increased strains. In turn, various form factors for the actuator configuration are presented including an artificial circular muscle and a strain amplifying pulley system. Other actuator configurations are contemplated that include independent and opposed electrode pairs to create cyclic activation, hybrid electrode configurations, and use of strain limiting layers for controlled deflection of the actuator.

In one embodiment, a wax motor may provide the motive force to toggle a latching mechanism. An actuator may be capable of positioning an output pin in two or more discrete latching positions and may be used to create a thermal connection between two structures, to engage or disengage a clutch, or to position an optical element in an optical instrument. An actuator may also be used as a launch lock apparatus.
