  • Publication number: 20020014023
    Abstract: An insole (20, 90, 110) provides for adjustable pediatric support characteristics for a user's foot. One or more pairs of stacked rotor and stator resilient elements (34, 36) are supported by the insole. Each pair of resilient elements is characterized by having a greater resiliency when the rotor is oriented along or at 90° with respect to the stator. The rotor is relatively movable with respect to the stator to effect different orientations of the paired rotor and stator and enables the blending of the respective resiliences of the pair and, thereby, for providing the adjustable pediatric support characteristics. A plurality of rotor and stator pairs enables adjustments for different parts of the foot and for differences between an individual's feet.

  • Publication number: 20020007568
    Abstract: A heel cup (44) permits the user to custom fit each foot to various shaped footwear, using adjustable bottom wall and side wall cushions (76, 246), thereby providing optimum comfort and safety whether simply walking or during vigorous sports activity. The heel cup includes bottom, side and heel portions (72, 74), an attachment mechanism secured at least to one of the portions, and an insole (54, 78) secured to a hook and loop attachment mechanism for supporting the foot. A complete adjustable insole is together used with an adjustable sidewall cushioning because it is difficult to reach into the interiors of footwear to make adjustments, such as installing moving or removing a cushion to obtain necessary comfort. Attachments for the insole may comprise tabs (158, 172, 188) to which the insole can be secured. A heel grip bracket (420) with a cushion (422) may be mounted on the heel portion of the bracket and one or more cushions (438) may be coupled to cushion (422) on its sides.

  • Patent number: 6205685
    Abstract: A shoe insert that can be customized by the user to control pronation of the foot and to relieve or reduce stress at painful areas of the foot comprising a sheet of a natural material such as leather or a synthetic resin such as high density polyethylene capable of being deformed to the shape of the foot by the weight of the user. The sheet includes fastening hook or loop material on at least one surface whereby detachable cushioning elements can be attached to the film. The fastening material attached to the sheet is preferably a layer of loop cloth that continuously covers one or both surfaces of the sheet. The cushioning pads also contain a sheet of loop or hook material on one or both surfaces. When the insert with attached, spaced pads is placed in a shoe, the sheet deforms around and between the compressible pads due to the weight of the user and retains the shape when the weight is removed.

  • Patent number: 6000147
    Abstract: An orthotic which comprises an upper section and a lower section which can be hinged to each other by a hinge. The facing surfaces of the sections are covered with sheets of loop material. Compressible cushion pads designed to contour to the specific needs of a patient containing a layer of hook material on both surfaces are releasably secured to the sheets of loop fabric forming a three layer assembly.

  • Patent number: 5799414
    Abstract: A shoe insert that can be customized by the user to control pronation of the foot and to relieve or reduce stress at painful areas of the foot comprising a film of plastic capable of being deformed to the shape of the foot by the weight of the user. The film includes fastening hook or loop material on at least one surface whereby detachable cushioning elements can be attached to the film. The cushioning element is preferably a sheet of loop cloth that continuously covers one or both surfaces of the film. The cushioning pads also contain a sheet of loop or hook material on one or both surfaces. The pads can be inclined to affect pronation or can contain apertures to relieve stress. The outer edges of the pads and the upper edge of the aperture are preferably chamfered or rounded to reduce discomfort.

  • Patent number: 5178934
    Abstract: To produce a layer in a multi-layer circuit structure, a "green ceramic tape" (16) comprising a sheet of particles of ceramic, glass ceramic, or a glass/ceramic composite in an organic binder is applied to a ceramic substrate (12) on which conductive paths (14) have been deposited. A slurry of hollow microspheres (20) is then deposited onto the green ceramic tape (16), and pressure is applied to drive the spheres into the tape. A further tape layer (22) is then applied, and the resultant structure is fired.
