Abstract: A roof panel includes a first member and a second member. A panel is attached to and interconnects the first member and the second member. The panel is configurable between a deployed configuration for attachment to a vehicle, and a stowed configuration for storage. The panel has a planar form when in the deployed configuration, and a rolled up form when in the stowed configuration. The panel may include an adjustable stiffness panel, such as a layer jamming panel, controllable in response to a control signal to exhibit a first stiffness when in the deployed configuration or the stowed configuration, or a second stiffness for reforming the panel between the deployed configuration and the stowed configuration.

Abstract: An inflatable structure includes a top end cap, a bottom end cap, a bladder, a nozzle, a loop, and a first tether. The bladder is attached to the top and bottom end caps and is configured to hold pressurized fluid therebetween. The nozzle is configured to allow fluid to enter and exit the bladder. The loop is attached to one of the top and bottom end caps. A tether is disposed within the bladder, coupled to the other one of the top and bottom end caps, and extends through the at least one loop. The top end cap assumes a first position when the bladder is inflated. When the top end cap is adjusted from the first position to a second position, the first tether is configured to maintain the top end cap in the second position.

Abstract: Systems and methods are provided for shape controlled gripping of a workpiece. A layer jamming structure includes a membrane defining an internal cavity containing a number of overlapping material layers. A pressure system includes a pump coupled with the internal cavity. A shape conforming tool includes at least one part configured to move to apply a force to the layer jamming structure. The shape conforming tool, by operation of the part, conforms the layer jamming structure to the workpiece. The pressure system, with operation of the pump, changes a pressure in the internal cavity to impart rigidity to the layer jamming structure.

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: 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 pressure regulator includes an inlet channel, an outlet channel, a bladder, a first plate, and a second plate. The bladder is connected to the outlet channel and extends alongside of the inlet channel. The first plate is disposed on one side of the inlet channel between the bladder and the inlet channel. The second plate is disposed on the other side of the bladder and is at least partially aligned with the first plate along the length of the inlet channel such that a portion of the inlet channel is disposed between the first and second plates. When the bladder is pressurized, the bladder urges the first plate toward the second plate and thereby pinches the portion of the inlet channel disposed between the first and second plates to regulate a ratio of a pressure in the outlet channel to a pressure in the inlet channel.

Abstract: A method of forming a spacer fabric includes performing, via a knitting machine, an iterative process. The iterative process includes: knitting a tether from a first point to a second point on a first fabric layer; extending the tether from the second point to a third point on a second fabric layer to start formation of a tether segment; temporarily holding the tether at the third point via one of a temporary holding needles; extending the tether from the third point to a fourth point on the first fabric layer; temporarily holding the tether at the fourth point via another one of the temporary holding needles; extending the tether from the fourth point to a fifth point on the second fabric layer; and knitting the tether from the fifth point to a final point on the second fabric layer. The tether segment is released from the temporary holding needles.

Abstract: A multi-layer bladder includes: a first bladder layer; a mask including a plurality of apertures; a second bladder layer bonded to the first bladder layer within the apertures in the mask and where the mask is not present between the first and second bladder layers, where the mask is configured to prevent bonding of the second bladder layer to the first bladder layer where the mask is present; and a fluid channel that is located between the first and second bladder layers and that extends to the mask from an outer edge of the multi-layer bladder.
