  • Patent number: 6099940
    Abstract: The present invention provides a selectively-activatible sheet material for delivering a substance to a target surface. The sheet material comprises a three-dimensional sheet of material having a first side and a second side. The first side has a plurality of hollow protrusions extending outwardly therefrom and separated from one another by valleys, while the second side has a plurality of depressions corresponding with the hollow protrusions. A substance adheres to and partially fills a location protected from external contact comprising the valleys and/or depressions. The sheet material may be selectively activated by deforming the hollow protrusions to deliver the substance to a target surface. The three-dimensional structure includes hollow protrusions which are adapted to progressively activate in multiple discrete stages to effect multistage progressive delivery of the substance to the target surface.

  • Patent number: 6093468
    Abstract: Disclosed is an improved protective pad for protecting the human body against impact forces. The pad is formed using layers of high density closed-cell polymer foam low density closed-cell polymer foam, and resilient or non-resilient energy absorbing inserts. The high density layer absorbs and shunts impact forces, while the low density layer acts as a cushion against the human body, and provides for comfort. The pad can be provided with a plurality of holes through its thickness to provide for breathability and release of heat from the human body, the surface area of the holes being great enough to allow for adequate ventilation but not so great as to significantly decrease the protection offered by the pad. The pad can also be provided with a plurality of score lines across its surface and partially through its thickness to provide for flexibility and conformability to the part of the human body being protected.
