Patent CA-2824656-A1 (CA)
Inventor: MAZZOCCHI RUDY
IPC: A61F2/16
Filed: 2011-12-28
Abstract: An implantable ophthalmic device with one or more optical elements coupled to one or more shape-memory members provides dynamically variable optical power to restore lost accommodation in individuals suffering from presbyopia or aphakia. Running current from a power supply through the shape-memory members causes the shape-memory members to heat up. Once the current heats the shape-memory members past a forward phase-transition temperature, the shape-memory members change shape, which, in turn, causes the optical element(s) to move, yielding a corresponding change in effective optical power. Cooling the shape-memory members (e.g., by reducing or stopping the flow of current) below a reverse phase-transition temperature causes the shape-memory members to return to their original shape, which, in turn, restoring the optical element(s) to their original positions and returning the effective optical power to its original level.

IPC: B29C43/28
Filed: 2012-06-27
Abstract: A microporous insulation material mixture which may comprise fumed silica, IR opacifier, and fibres of organic or inorganic material is blended and the blended mixture is spread across a lower conveyor belt (72) which is trained over rollers (73, 74). To aid the spreading of the mixture a spreading device (70) is used. The spreader unit (70) extends across the width of the main belt (72) to ensure an even spread of the mixture. The spreader (70) is used to set the height of the material being delivered onto the belt (72). The mixture is delivered by the conveyor (72) to a pressing system which in this case comprising an upper conveyor belt (71) which is trained over rollers (75), (76). The upper roller (75) at the inlet end is located to provide a lead-in pressing action. The pressing system also comprises a nipping means provided in this case by a plurality of upper and lower nipping rollers (78, 77). The gaps between the individual rollers (78, 77) is adjustable. The first rollers (78, 77) at the input end may be set to a gap of 25mm and the others set to gradually reduce the gap to about 20mm between the final rollers (78, 77) at the output end. An upper fleece liner (80) is led from a delivery roller (81) to lie between the upper conveyor belt (71) and the insulation mixture. Similarly, a lower fleece liner (82) is fed from a delivery roller (83) to lie between the insulation mixture and the lower conveyor belt (72). The fleece liners (80, 82) may continue through the process and may be used to encase the core (40) prior to enclosing in an envelope (50) and applying a vacuum.
