Abstract: A shape memory alloy composite fabric and a method of use is provided in underwater pressure vessels and as flexible joints in atmospheric diving suits. The atmospheric diving suit internal pressure is one atmosphere for underwater transit to and from an underwater work site. During operations at a work site, the shape memory alloy joints transform to a martensite phase and enable greater flexibility while the pressure in the atmospheric diving suit equalizes with ambient depth pressure.

Abstract: A device for retaining an electronically readable card in an electronic device includes a substantially V-shaped resilient retainer dimensioned to engage a portion of the card while the rest of the card remains exposed for electronic reading purposes. The resilient retainer is held in the electronic device by a clip having a first detent member. The retainer includes a second detent member which engages the first detent member as the retainer enters the slit during insertion of the card into the electronic device. The thicknesses of the retainer and the card and the width of the slit are selected so that the resilient retainer is firmly held in the electronic device.

Abstract: A shoe sole construction is provided with a flexible bladder which is only partially filled with a non-compressible fluid. Preferably the fluid is water. The partially filled water bladder allows the water to flow from one portion of the bladder to other portions of the bladder during the walking cycle to provide proper support and maximum comfort and stability for the wearer of the shoe.
