摘要： A deformable membrane assembly 1 comprising a fixed support; a fluid-filled envelope, one wall of which is formed by an elastic membrane 8 that is held under tension around its edge by a flexible membrane supporting member 2, 10, the membrane supporting member being coupled to the fixed support at a plurality of discrete control points 120 round the supporting member by respective engaging members for controlling the position of the membrane edge relative to the fixed support at the control points, and the member being unconstrained between said control points; and a selectively operable pressure adjuster for adjusting the pressure of the fluid within the envelope, thereby to adjust the shape of the membrane; wherein at least three control points are provided which are situated round the membrane edge at spaced locations on the member that are selected to increase the energy of the lowest order out-of-plane bending modes of the supporting member in response to loading through tension in the membrane that do not have a node round the whole supporting member. The invention further provides an article of eyewear comprising a deformable membrane assembly of the types described.

摘要： The present invention provides a deformable membrane assembly 1 comprising an elastic membrane 8 that is held under tension around its edge by a bendable membrane supporting member 2,10, a body of fluid in contact with one face of the membrane, the pressure of the fluid being controllable for adjusting the shape of the membrane, and one or more bending controllers 24 acting on the supporting member 2, 10 to control the bending of the supporting member in response to loading through tension in the membrane. The bending stiffness of the membrane-supporting member 2, 10 varies round its extent to control the profile of the edge of the membrane 8; etc. upon actuation. A variety of different types of bending controllers are disclosed which permit out-of-plane bending of the supporting member 2, 10 but prevent or control in-plane bending or deformation of the supporting member. In some embodiments, the bending controllers permit a degree of controlled in-plane bending of the supporting member 2, 10 in order to control the strain in the membrane 8 upon actuation.
