Abstract: An inflatable structure includes a top end cap, a bottom end cap, a bladder, a plurality of tethers, and an adjustment mechanism. The bladder is attached to the top and bottom end caps and configured to hold pressurized air therebetween. The plurality of tethers are disposed within the bladder. Each tether in the plurality of tethers has a first end coupled to the top end cap and a second end coupled to the bottom end cap. When the bladder is inflated, the plurality of tethers restrict a number of degrees of freedom of the inflatable structure and a type of the degrees of freedom. The adjustment mechanism is operable to move the second end of at least one tether in the plurality of tethers to adjust at least one of the number of the degrees of freedom and the type of the degrees of freedom.

Abstract: A selectively rigidizable membrane for cargo management comprises a vacuum bladder, and a first architectural layer and a second architectural layer, each of the first and second architectural layers including a plurality of tiles interconnected by flexural elements, each of the tiles of the first and second architectural layers including at least one constraining element extending therefrom, wherein, when atmospheric pressure is present within the vacuum bladder, the first and second architectural layers are slidably moveable relative to one another and the membrane is flexible, and further wherein, when negative pressure is applied to the vacuum bladder, the first and second architectural layers are forced into engagement with one another, the constraining elements of the first and second architectural layers providing mechanical interference and preventing sliding movement of the first and second architectural layers relative to one another, causing the membrane to become substantially rigid.

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: A textile comprising: i) a fabric including a laced region associated with a surface of the textile; and ii) a thread inlaid through a plurality of points proximate a perimeter of the laced region. Tightening the thread causes opposite sides of the laced region to be cinched together, thereby forming the laced region into a flap associated with a second surface of the textile opposite the first surface. The textile further comprises a listing wire disposed in the flap. The fabric forms a plurality of perforations within the laced region. The listing wire may be accessed by an attachment device through at least one of the plurality of perforations.

Abstract: Cargo systems are provided for vehicles that include, in one embodiment: a variable cargo surface disposed within a body of the vehicle behind one or more occupant seats, the variable cargo surface including: a low friction surface that facilitates movement of cargo within the cargo system, the low friction surface having a first coefficient of friction; a high friction surface that inhibits movement of cargo within the cargo system, the high friction surface having a second coefficient of friction that is greater than the first coefficient of friction; and a control device that selectively activates the low friction surface and the high friction surface based on conditions for the vehicle; wherein the low friction surface contacts the cargo within the cargo system when the low friction surface is activated; and the high friction surface contacts the cargo within the cargo system when the high friction surface is activated.

Abstract: A vehicle seat includes a first knitted fabric layer defining an outer surface and a second knitted fabric layer defining an inner surface. The inner surface is opposite the outer surface. The vehicle seat further includes a knitted spacer fabric interconnecting the first knitted fabric layer and the second knitted fabric layer. The knitted spacer fabric resiliently biases the first knitted fabric layer and the second knitted fabric layer away from one another. The knitted spacer fabric is configured to buckle when a seated occupant exerts an occupant load on the vehicle seat. The first knitted fabric layer is more elastic than the second knitted fabric layer to conform to the seated occupant when the seated occupant exerts the occupant load on the vehicle seat.

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.
