Abstract: A polymeric material with a variable modulus of elasticity is described herein. The polymeric material described herein is useful for forming implantable medical devices (e.g. ophthalmic lenses, breast implants, and body augmentation devices). In addition, medical devices formed from the polymer material can be used to controllably release a therapeutic agent. Also, the polymeric material may be used to prepare topical compositions or other applications or devices where control of a mechanical property such as material modulus is important.

Abstract: The present invention provides an apparatus, method and system for producing water flow within a pool or spa. A pump body contains a pump assembly with an impeller for aspirating water. A driving device connects to the impeller. A jet nozzle, which may be pivotable, directs water out of the pump. A front cover comprises a water intake inlet distal from ajet nozzle front cover opening. The front cover water intake inlet may be positioned to allow water flow into the apparatus substantially in a direction normal to water flow out of the apparatus. Impeller vanes may have angled front-side vane edges. Vanes may thicken with distance from the impeller center. A radius of curvature for an inside impeller vane surface may be less than a radius of curvature for an outside impeller vane surface. A radius of curvature for impeller vanes may decrease away from the impeller center.
