Abstract: A hand-held device is used to deliver and hydrate a temporary polymeric implant having a length, an outer surface and a cross-section, with a disruptable cover over the implant. A lumen may pass through the entire length, the lumen having a surface forming an equivalent diameter in the polymeric stent. The temporary polymeric implant includes a first aqueous-swellable, biocompatible and biodegradable composition (e.g., polymer) having a thickness. The aqueous-swellable and biodegradable polymer retaining structural integrity for at least 1 hours up to thirty days when swollen and kept moist by a moist aqueous environment. Barrier layers of biodegradable polymer(s) may be used to prevent migration of liquids into the lumen.

Abstract: An image projection system is provided that includes a projector configured to generate a visible projected image, a screen having an interior surface enclosing a three-dimensional space, and a reflector configured to receive the visible projected image from the projector and to reflect the visible image on the interior surface of the screen, the reflector having an aspherical reflective surface that adapts the visible image from the projector for display on the interior surface of the screen, ideally without distortion and without using software warping, to provide complete coverage of the interior surface of the screen.

Abstract: The invention provides a business platform, a business entity management system, and a software module that can be used in conjunction with the software service framework. The invention mimics actual business relationships between business entities, and uses a software service module to configure the business entities into a network that comprises at least three generations of business entities, wherein role dependent associations mimicking real life business relationships are established between the business entities. The invention provides management of active content in a website and allows modification of the content by different business entities. Control of the active content is determined by precedence of the business entities.
