A multi-layered textile panel for use in manufacturing cooler type bags includes an outer set of layers and an inner set of layers. The outer set of layers (12, 14, 16) and inner set of layers (24, 22, 18) are stacked and laminated together under pressure and heat. The laminating is performed in a predetermined pattern (110) to allow for the creation of gel cavities (120) and soft or living hinges (112) in the panel. A gel injection site (202) is maintained open in a first lamination process. The gel is injected into the gel cavities via the gel injection site and once injection is complete, the gel injection site is closed using the lamination process. The gel infused panel may now be cut and assembled into a desired bag or other shape for use.

A step platform for aerobic exercise may include multiple layers. The top layer may include an elastic foam member that is configured to at least partially deform when stepped on by a user. The middle layer may include a rigid support member that is configured to at least partially maintain the shape of the foam member. The foam member may include a cover that wraps around the foam member and at least a portion of the support member to fasten the support member to the foam member. The bottom layer may include a base member having a support ridge configured to at least partially restrict deformation of the foam member in at least one direction. The base member may be connectable to the support member.

摘要:
A thermal/acoustic insulation product, such as for an aircraft, comprising a block of flexible, open-celled, cellular foam having a predefined shape and having a thermoformed amorphous film covering that completely envelops the foam block. A process for making the insulation product includes first cutting the block of foam to a predefined shape, such as a shape suitable for placement in an area of an aircraft in need of insulation. Then, a first sheet of film is heated to its melt point and conformed to a first surface area of the block, and a second sheet of film is heated to its melt point and conformed to a second surface area of the block, wherein the first film and the second film are joined to one another at one or more seams. The insulation product may then be installed in an aircraft.
