Abstract:
Control mechanisms and methods of use include the use of active materials as a blocking element. The control mechanisms generally include a tactile control (14) in operative communication with an electrical circuit (16), wherein actuation of the tactile control closes the electrical circuit to activate a function. The blocking element (12) includes an active material that is intermediate to the electrical circuit and the tactile control. The active material is adapted to change at least one attribute such as a modulus property in response to an activation signal. The change in the at least one attribute selectively changes a force level for actuating the tactile control.
Abstract:
A morphable vehicle member utilizing at least one active material to change at least one attribute in response to an activation signal. The change in at least one attribute is a change in a shape dimension, a shape orientation, an expansion, a contraction, a morphing, a yield strength property, a flexural modulus or a combination. Preferably, the change in at least one attribute in the morphable vehicle member is reversible. Also disclosed herein are methods for the morphable vehicle member utilizing at least one active material to change at least one attribute on demand in response to an activation signal.
Abstract:
A reversible energy absorbing assembly including a cellular lattice comprising a shape memory material disposed within an expandable interior region of the assembly, wherein the shape memory material is adapted to expand from a first configuration to an expanded configuration in response to fluid communication with a fluid source. Once expanded, the assembly effectively absorbs kinetic energy of an object upon impact with the assembly. The shape memory material can be thermally activated to restore the first configuration of the energy absorbing assembly. Methods of operating the energy absorbing assembly are also disclosed.
Abstract:
A panel (10) having active material based segments (14), wherein the segments define a hinge location that can be selectively stiffened or folded on demand. The active material based segments include an active material such that activation of the active material by an activation device can allow folding of the panel, can effect self-folding of the panel, or can serve to lock the panel into a fixed position when to activated. In this manner, the panel that can be variously stiffened or folded on demand. Other embodiments include forming the panel of the active material such that the panel can be compacted and stowed upon activation of the active material to change the modulus properties thereof.
Abstract:
A voice activated control interface system for selectively lighting and/or highlighting a control interface for a function generally includes a microphone for receiving a voice command; at least one control interface in operative communication with a function; and a controller in operative communication with the at least one microphone and the at least one control interface, wherein the controller is adapted to process a voice command to provide a signal to a specific one of the at least one control interface to light and/or highlight the at least one control interface. Methods for operating the voice activated control system are also disclosed.
Abstract:
A volume-filling mechanical structure comprising a honeycomb celled material expandable from a compact state to an expanded state and methods for operating the same.
Abstract:
Reconfigurable structures include at least one hub, a plurality of arms attached to and extending from the at least one hub, wherein at least a portion of the arm and/or hub defines a node and is formed of an active material. The active material is adapted to change at least one attribute in response to an activation signal, wherein the change in the at least one attribute changes a modulus property, a shape orientation, or a combination of the modulus property change and the shape orientation change to the active material portion. The plurality of arms and at least one hub can form a reconfigurable opening for attaching and releasing a member. Alternatively, the plurality of arms and/or hub can further include a connector for attaching an additional structure. Also disclosed herein are methods for selectively reconfiguring a structure.
Abstract:
A control system for selectively lighting and/or highlighting a control interface for a specific individual function generally includes at least one sensor for detecting at least one condition; a controller in operative communication with the at least one sensor and the control interface; wherein the controller sends an output signal to the control interface in response to detecting the at least one condition, wherein the output signal is effective to light and/or highlight the control interface for the specific individual function. Methods for operating the control system are also discussed.
