  • Patent number: 11623718
    Abstract: A beanbag comprising a first layer, forming a generally closed container, a layer of cushioning lining an inside of the first layer, a cavity within the closed container, and a resealable access port to access the cavity. In a preferred embodiment, the first layer is marine vinyl, the cushioning is a uniform layer of marine foam, and the resealable access port is a marine-grade zipper. In another embodiment, the cushioning is a layer of beanbag beans. In another embodiment, the resealable access port is an opening at the end of a protrusion, wherein the protrusion can be rolled-up and secured with a fastening mechanism. The beanbag is intended for, but not limited to, use outdoors, such as on the beach, the decks of boats, patios, pool sides, and in water. In a preferred embodiment, the beanbag floats on water and further comprises a reflective band and reflective elements.

  • Patent number: 11395580
    Abstract: A medical device includes an inner element and an outer element positioned at least in part around the inner element. At least one of the inner element and the outer element comprises compression-stiffening particles. The compression-stiffening particles are transitionable from a first state to a second state in response to application of pressure. The compression-stiffening particles have a higher rigidity in the second state than in the first state. The medical device also includes a pressure source operably coupled to one or both of the inner element and the outer element to apply pressure sufficient to transition the compression-stiffening particles from the first state to the second state.

  • Publication number: 20150000042
    Abstract: A pillow relies on a shell containing two types of fill material, one comparatively smaller, granular, and characterized by a comparatively larger spring constant, and another comparatively larger, more chunky in shape, and characterized by a comparatively smaller spring constant. Below a threshold level of force (or pressure, which is force per unit area) the larger, softer, second fill material resists flow of the smaller, harder, stiffer fill material. However, upon application of a force (or pressure) above some threshold, the mixture of the two fill materials will flow to conform the pillow to the shape of a user. The pillow will then substantially stabilize in that shape in the absence of forces above the threshold level.

  • Patent number: 8732878
    Abstract: A method and apparatus are disclosed for a method for securing a patient for a medical procedure and specifically for an innovative headrest system for securing a patient for an ocular imaging procedure. The approach avoids the need for linkages and sliding rods and such. Instead, it relies on three independently movable face rests (two for the forehead or temples and one for the chin) each with a deformable cushion that is urged into conformity with the patient's head and chin during an adjustment phase of operation. Once a comfortable position and suitable conforming shape is achieved, the positions of the face rests are rigidly fixed and the shape of the cushions are rendered rigid and non-deformable, by application of a light vacuum, for the procedural or imaging phase of operation.

  • Patent number: 6651282
    Abstract: A flexible, crescent shaped pillow to assist mothers to maintain an anatomically correct alignment between mouth and nipple while breast feeding. This alignment is a key factor in ensuring optimum flow of milk. The pillow is both highly flexible and supportive. These are the key features that make it an effective aide to breast feeding mothers. These properties are achieved through the use of a low density bead filling which can shift and flow within the casing, thus providing the correct support where it is needed. The pillow is designed to be used while feeding in a variety of positions and from either breast. Use of the pillow also reduces fatigue and stress for both baby and mother while nursing. The bead filling allows for the passage of air and liquids through the pillow. This contributes to increased safety in terms of reduced risk of suffocation. and less opportunity for the growth of mold and bacteria.

  • Patent number: 6611980
    Abstract: The present invention is directed to a custom-contoured cushion for a wheelchair or other seating device and a method of making the same. In one embodiment, the novel custom-contoured cushion is comprised of a stretchable bag filled with soft and resilient closed-cell foam pellets adhered together by and/or embedded within an elastomeric polymerizable adhesive. The pellets do not absorb a significant amount of the adhesive and, after molding, remain sufficiently soft and resilient to provide a comfortable and durable cushion. Alternatively, the cushion contains soft and resilient pellets, but does not contain the elastomeric polymerizable adhesive. In the first embodiment, the custom-molded, custom-contoured cushion is made by mixing the pellets with the adhesive to form a pellet/adhesive mixture, positioning the user on a bag filled with the pellet/adhesive mixture, molding the mixture around the user to provide cushioning around the user's seating surface, and allowing the adhesive to cure.

Preferred embodiments of the shape retainer include a vacuum activated bean bag, a plurality of pressurizable chambers, a thermally deformable plastic sheet, and an array of pivot elements which are mechanically clamped together.
