Abstract: An inflatable insulation panel includes a bladder configured to contain air, plurality of tethers disposed within an interior cavity of the bladder, and at least one reflective film disposed within the interior cavity of the bladder. The bladder includes a first wall, a second wall opposite of the first wall, and perimeter walls extending between and connected to perimeter edges of the first and second walls. The first and second walls and the perimeter walls collectively defining the interior cavity of the bladder. The plurality of tethers extend between and are connected to interior surfaces of the first and second walls. The plurality of tethers limit movement of the first and second walls away from one another when the bladder is inflated. The at least one reflective film is disposed between the interior surfaces of the first and second walls.

Abstract: A vacuum cup assembly and a method of lifting an object are provided. The vacuum cup assembly includes a cup structure defining an opening at a proximal end, a recess at a distal end, and a cavity region between the proximal and distal ends, where the cavity region includes at least one cavity. The opening is in fluid communication with the recess and with the cavity region. Inner structures are disposed in the cavity region. The inner structures are configured to hold the cup structure in a gripping position when a negative pressure is applied to the cavity region through the opening in the cup structure. The cup structure is configured to be in a resting position without the negative pressure being applied to the cavity region. The vacuum cup assembly has a first shape in the resting position and a second shape in the gripping position.

Abstract: A stretchable adjustable-stiffness assembly includes a casing and first and second friction layers. The casing can be fluidly sealed and includes an interior compartment containing a fluid. The fluid can shift between a first interior pressure and a second interior pressure less than the first interior pressure and an exterior pressure. The first and second friction layers are disposed within the interior compartment. The assembly can shift between relaxed and fixed configurations. In the relaxed configuration, the fluid has the first interior pressure, the casing is stretchable between a first dimension and a second dimension greater than the first dimension, and the assembly has a first stiffness. In the fixed configuration, the first fluid has the second interior pressure, the casing length is fixed, the first and second friction layers are engaged, and the assembly has a second stiffness greater than the first stiffness.

Abstract: A vehicle includes a passenger compartment having a roof structure having a front header, a pair of side headers and a rear header. A headliner is disposed beneath the roof structure. At least one inflatable bladder is disposed along at least one of the front header, the pair of side headers and the rear header. The at least one inflatable bladder is connected to an inflator. A rib structure is disposed adjacent to the at least one inflatable bladder. The inflatable bladder inflates to a maximum height of 12 cm below the at least one of the front header, the pair of side headers and the rear header.

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.
