Patent number: 10823981Abstract: A deformable membrane assembly comprises an at least partially flexible fluid-filled envelope, one wall of which is formed by an elastic membrane that is held around its edge by a resiliently bendable supporting ring, a fixed support for the envelope and selectively operable means for causing relative movement between the supporting ring and the support for adjusting the pressure of the fluid in the envelope, thereby to cause the membrane to deform. The bending stiffness of the ring varies round the ring such that upon deformation of the membrane the ring bends variably to control the shape of the membrane to a predefined form. The moving means comprise a plurality of ring-engaging members that are arranged to apply a force to the ring at spaced control points.Type: GrantFiled: September 25, 2019Date of Patent: November 3, 2020Assignee: ADLENS LTD.Inventors: Robert Edward Stevens, Alex Edginton, Benjamin Thomas Tristram Holland, Daniel Paul Rhodes, Dijon Pietropinto, Derek Paul Forbes Bean, Roger Brian Minchin Clarke, Peter Lee Crossley, Richard Leefe Douglas Murray, Edwin James Stone
