A distributed inflatable touch sensing system is provided. The distributed inflatable touch sensing system includes a sensing bladder array, the sensing bladder array having a plurality of bladders, passageways, and ports in fluid communication. The system further includes a pressure regulator in fluid communication with one of the plurality of ports for regulating a pressure in the sensing bladder array. The system further includes a plurality of sensors, each in fluid communication with one of the plurality of ports, for measuring the pressure in the sensing bladder array. The system further includes a processor in communication with the plurality of sensors. The processor is configured to determine which of the plurality of bladders has been depressed by a user.

A pneumatic shade includes a plurality of slats, a plurality of first fold members, and a plurality of second fold members. Each slat is elongated and includes and spans laterally between opposite longitudinal edges. Each of the first- and second-fold members are elongated and co-extend longitudinally with the slats. Each first fold member is attached to longitudinal edges of the respective adjacent slats. Each second fold member is attached to longitudinal edges of respective adjacent slats and are alternatingly orientated with respect to the first fold members such that each slat spans laterally between a respective first fold member and second fold member. Each of the first fold members and the second fold members are adapted to move between a folded state and an unfolded state upon application of pressurized air.

An incrementally assembled skin-constrained inflatable bellows system includes a top end cap, a bottom end cap, and a bellows attached to and separating the top end cap and the bottom end cap and configured to hold pressurized fluid between the top and bottom end caps. The system further includes a nozzle configured to allow fluid to enter and exit the bellows, and an inextensible skin attached to each of the top end cap, the bottom end cap, and to the bellows. The top end cap assumes a first position when the bellows is inflated via the nozzle and, when the top end cap is adjusted from the first position to a second position, the skin is configured to maintain the top end cap in the second position and constrains the bellows into a predefined rigid three-dimensional shape.

Skin constrained inflatable bellows

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.

Masked fabrication inflatable devices

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.

Selectively rigidizable membrane

A pneumatic articulating structure includes a plurality of tiles, a flexible cover, and a plurality of resiliently flexible hinges. Each tile has a first surface and a second surface facing in opposite outward directions. An area of at least one respective first surface is greater than an area of at least one respective second surface. The cover is constructed to cover the tiles. The second surface of each one of the tiles is attached to the cover. Each tile is engaged to an adjacent tile by a respective hinge, and are proximate to the first surface. A vacuum chamber is define by at least the plurality of tiles and the flexible cover.

Pneumatic articulating structure system with internal tile architecture

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.
