Abstract: A tensioning device for attaching to the anterior capsule of an eye, and accommodative intraocular lens systems employing the device. The tensioning device includes a biocompatible, elastically reconfigurable ring for restoring at least a portion of the anterior capsule centripetal forces lost by capsulorhexis. The tensioning device also includes a plurality of penetrators configured for attaching the ring to the anterior capsule. The plurality of penetrators is biocompatible with the eye and partially embedded in a part of the ring configured for facing the anterior capsule.

Abstract: Water saver fire hydrants save water by delivering their initial flow from a pilot valve to a collection of holes in the gasket faces of their hose and pumper outlet nozzles. These holes are normally closed off by the gaskets in caps and hoses, and the water that flows from those holes in the absence of those caps or hoses activates a mechanism inside the hydrant that either blocks attempts to obtain full flow from the hydrant or powers a hydraulic motor that closes the hydrant valves.
