Abstract:
An interface device, comprising:at least one foil assembly, with said foil assembly comprised of a plurality of flexible foils (28), said foils extending between a first surface (30, 30â€²) and a second surface (32, 32â€²) and in a length direction, with each foil comprised of a proximal edge (34) near said first surface, a flexing section (36), and a distal edge (38) near said second surface, said foils within said foil assembly are stacked in a densely-packed, nested fashion with said proximal edges of adjacent foils distributed with a proximal edge spacing factor (48) and said distal edges of adjacent foils distributed with a distal edge spacing factor (50) so that interstitial separation distances (42) are provided between said flexing sections of adjacent foils to accommodate flexing and compression of the distance between said first surface and said second surface to a desired minimum for said foil assembly, and wherein said distribution of proximal edges with said proximal edge spacing factor (48) and said distribution of distal edges with said distal edge spacing factor (50) being established and made generally fixed when said distance between said first surface (30, 30â€²) and said second surface (32, 32â€²) is at said minimum for said foil assembly and said interstitial separation distances (42) between said flexing sections of adjacent foils being generally depleted and said flexing sections of adjacent foils are contacting each other for most of their surfaces.
