Abstract: Forming a cured composite structure may include assembling pre-cure members about a variable volume support member to form a pre-cure assembly, applying an internal pressure from within the pre-cure assembly by maintaining the variable volume support member at an expanded volume, and curing the pre-cure members by applying heat while the variable volume support member is in the expanded volume to form a cured composite structure.

Abstract: A prosthetic foot device with variable stiffness response includes a variable energy transfer mechanism or variable resistance cell disposed between first and second foot members to transfer a variable amount of energy from the second member to the first member during use. The energy transfer mechanism or variable resistance cell includes a variable orifice with variable size to variably resist flow of fluid therethrough, and thus variably transfers energy between the first and second members to vary stiffness of the prosthetic foot device.
Abstract: A method is disclosed for bonding structural elements together by injecting a liquid adhesive into a flow channel created by two strips of double sided adhesive tape and the two structural elements to be joined. The double sided adhesive tapes hold the structural elements in position while the adhesive is cured, thus forming a permanent bond between the structural elements.
