Patent ID: 7140081

Claim:
A releasable fastener system comprising: a loop portion comprising a loop support and a loop material attached or supported by the support; a hook portion comprising a support, and at least one hook element attached to the support, wherein the at least one hook element comprises a hollow interior region in fluid communication with at least one perforation in the support; and means for increasing or decreasing a pressure within the hollow interior region upon receipt of an activation signal to provide the at least one hook element with a change in shape orientation, a change in flexural modulus property, oil combination of a change in the shape orientation and the flexural modulus property, wherein the at least one hook element is adapted to engage the loop material in the absence of the activation signal and disengage from the loop material in the presence of the activation signal, wherein the shape orientation to the at least one hook element changes from an inverted J-shaped orientation to a substantially straightened shape orientation upon pressurization.
