摘要： 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.

摘要： A reinforced, foldable component for an aircraft is provided, configured to stabilize a high frequency aeroelastic fluttering movement. The reinforced component may include a frame structure defining at least one air chamber, and a plurality of sealed compartments. A shear thickening fluid is disposed in at least one of the sealed compartments, exhibiting a decreasing viscosity responsive to an impact force. The frame structure may define one of an inflatable wing structure, a fairing structure, an aileron structure, and a stabilizer structure, and the like. The foldable component may include an exterior layer with an exterior surface exposed to an external environment and an interior layer adjacent the at least one air chamber, wherein the plurality of sealed compartments are disposed between the exterior layer and the interior layer. The exterior layer or the interior layer may include an impact-resistant fabric layer including a shear thickening material.

摘要： A method of manufacturing an electrode assembly includes positioning a layer stack comprising an electrode positioned between an electrode insulator and a support polymer in a vacuum bag, removing air from the vacuum bag thereby vacuum coupling the electrode to the electrode insulator, and removing the layer stack from the vacuum bag, where upon removal of the layer stack from the vacuum bag, the electrode remains vacuum coupled to the electrode insulator and the electrode insulator is in direct contact with the electrode, thereby forming an electrode assembly.

摘要： An actuator that includes a shell, a ring structure within the shell, a shape-memory material wire fixed at opposite points of the ring structure to extend in a first direction across a width of the ring structure, and a cooling fluid provided within the shell and in fluid communication with the shape-memory material wire. When the shape-memory material wire is heated, the shape-memory material wire contracts in the first direction to reduce the width of the ring structure and increases a height of the ring structure extending in a second direction perpendicular to the first direction.

摘要： A remote actuator includes one or more bi-stable strips with at least one shape memory composite (SMC) spring connected to each bi-stable strip. The SMC spring includes a thermoplastic and an electrical and/or thermal conductor for transforming the length of the SMC spring upon heating. The contraction of the SMC spring transforms the bi-stable strip from its coiled stable state to its elongated stable state. The displacement of the SMC spring can be amplified by a simple machine included in the remote actuator. The remote actuator can include a shape memory alloy (SMA) strip for transforming the bi-stable strip from its elongated stable state to it curved stable state upon heating. Heating can be by Joule heating or from an adjacent heat source.

摘要： An actuating pillow includes a pillow body and a plurality of artificial muscles arranged within the pillow body. Each of the artificial muscles includes a housing having an electrode region and an adjacent expandable fluid region, an electrode pair positioned in the electrode region of the housing, and a dielectric fluid housed within the housing. The plurality of artificial muscles are configured to actuate from a non-actuated state to an actuated state, actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region and increases a height of the pillow body.

摘要： A support cushion liner includes a liner body having a cavity disposed between an outer layer and an inner layer and a plurality of artificial muscles disposed in the cavity of the liner body. Each of the plurality of artificial muscles include a housing having an electrode region and an expandable fluid region, a dielectric fluid housed within the housing, and an electrode pair positioned in the electrode region of the housing. The electrode pair includes a first electrode fixed to a first surface of the housing and a second electrode fixed to a second surface of the housing. The electrode pair is actuatable between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region thereby applying pressure to the outer layer of the liner body.

摘要： Actuators can be used in controlling a seat surface of a vehicle seat. The actuators can have an outer skin in connection with a hinge assemblies. The actuators can include a shape-memory material (SMM) member operatively connected to the hinge assemblies. The SMM member can be a shape-memory alloy (SMA) wire. The SMM member can change from a first configuration to the second configuration in response to an activation input, such as heat. The input can be delivered to the SMM member upon detecting an activation condition, such as detection of lateral acceleration. The actuators are operatively positioned relative to a seat surface such that, when the SMM member changes configuration, actuator causes the seat surface to morph.
