Abstract: A shield assembly is employed for a friction brake used to decelerate a road wheel of a vehicle. The vehicle has a body with a first body end configured to face an incident ambient airflow, a second body end opposite of the first body end, and an underbody section spanning a distance between the first and second ends. The shield assembly includes a first shield component arranged proximate the brake and rotationally fixed relative to the vehicle body. The shield assembly also includes a second shield component operatively connected to the first shield component for shifting relative thereto. The shield assembly additionally includes an actuator employing a shape memory alloy element to shift the second shield component relative to the first shield component in response to a temperature of the brake to thereby direct at least a portion of the airflow to the brake and control temperature thereof.

Abstract: A fabric assembly includes a knitted fabric and a filament. The knitted fabric is adapted to move between a stretched state extended along a direction of an applied force, and a relaxed state. The filament is disposed in the knitted fabric, and includes a plurality of loops longitudinally spaced apart from one-another. Each loop of the plurality of loops are adapted to project outward from the knitted fabric when in the stretched state, and substantially retract into the knitted fabric when in the relaxed state.

Abstract: The knitted textiles include a knitted structure including a plurality of hollow yarns. Each hollow yarn includes a yarn body and defines a yarn hole extending through the yarn body to allow expansion of the yarn body upon inflation of each hollow yarn through the yarn hole. The knitted structure is configured to transition from an unexpanded state to an expanded state in response to the inflation of the hollow yarns through the yarn hole. The knitted structure has a first porosity in the unexpanded state, and the knitted structure has a second porosity in the expanded state. The second porosity is less than the first porosity such that a visibility through the knitted structure is greater when the knitted structure is in the unexpanded state than when the knitted structure is in the expanded state.

Abstract: Presented are deployable structures having multi-stable-state characteristics using skeletal architectures mounted onto textile backings, methods for making/using such structures, and vehicle components having bistable characteristics provided by polymeric exoskeletons printed onto textile substrates. A multi-stable-state deployable structure includes an elastic substrate fabricated from a (knitted) textile sheet, and an articulating (polymeric) framework mounted on the knitted textile sheet. The articulating framework and textile sheet structurally cooperate to transition from a first stable state, in which the deployable structure maintains a substantially planar shape, to a second stable state, in which the deployable structure maintains a first multidimensional topography, and from the second state to a third stable state, in which the deployable structure maintains a second multidimensional topography distinct from the first multidimensional topography. The articulating framework may include an elongated spine sandwiched between first and second sets of ribs, and a frame circumscribing the spine and ribs.

Abstract: A motion sickness mitigation device includes a textile material having a first surface, a second surface disposed opposite the first surface, and a first raised portion extending from the first surface and configured for contacting a skin of a user. The textile material defines a first pocket and a second pocket therein between the first surface and the second surface, and the second pocket is spaced apart from the first pocket. The device further includes a controller disposed within the first pocket and configured for transmitting an electrical signal. The device also includes a first electrical excitation pad disposed within the second pocket, covered by the first raised portion, and disposed in electrical communication with the controller. The first electrical excitation pad is configured for receiving the electrical signal and electrically stimulating the skin of the user through the textile material to thereby mitigate motion sickness.

Abstract: A fluid flow control device includes a resilient substrate translatable between a first flattened position and a second extended position, and an actuator attached to the resilient substrate. The actuator is configured for translating the resilient substrate from the first flattened position to the second extended position. The actuator is formed from a shape memory alloy transitionable between a first state and a second state in response to a change in temperature of the shape memory alloy. A fluid flow control system includes a rotor shield and the fluid flow control device attached to the rotor shield.

Abstract: A conditioned apparatus defines a chamber, and includes a frame defining a door opening providing access to the insulated chamber and a door movable relative to the frame. The door selectively blocks the door opening. A seal disposed between the frame and the door, and a shape memory alloy (SMA) element is associated with, and may be knitted directly into, the seal. A controller operatively connected to the SMA element. The controller selectively provides heat to the SMA element, such that the seal changes from spanning between the door and the frame, when the temperature of the SMA element is below a phase-change temperature, to contacting only one of the frame and the door, when the temperature of the SMA element is at least the phase-change temperature.

Abstract: A dielectric elastomer actuator includes an elastomeric film and an electrode material layer on opposing sides of the film. The elastomeric film includes a first section, a second section, and a transition section disposed between the first section and the second section. The electrode material layers are disposed on the transition section and the first and second sections. The first and second sections are restrained in a pre-stretched configuration in an axial and a lateral direction, while the transition section is not restrained in the axial direction. The transition section elongates in response to the application of a voltage to the electrode material layers, such that the first and second sections move apart, in the axial direction. Likewise, the transition section is configured to contract in an absence of a voltage applied to the electrode material layers, such that the first and second sections move apart, in the axial direction.

Abstract: A method includes assembling a first latching device and a second latching device. The first latching device includes a first support housing and a first sliding assembly. The first sliding assembly is selectively movable, relative to the first support housing, between a latched position and an unlatched position. The second latching device includes a second support housing, a second sliding assembly, and an actuating mechanism. The second support housing is substantially identical to the first support housing. The second sliding assembly is selectively movable, relative to the second support housing, between a latched position and an unlatched position. The actuating mechanism is operatively disposed in the second support housing and is configured to selectively maintain the sliding assembly in the latched position until the actuating mechanism is selectively actuated. The first latching device does not include the actuating mechanism.
