Abstract: Embodiments of the present disclosure include methods of radiant heat rejection, and structures for use in same, where Aluminet® is provided in a roof or an attic of a building structure. The Aluminet® material is installed by providing a structure for the material to breathe, that is, the material is provided so that an air space surrounds it.

Abstract: An image map designer creates an image map for use with an image. The image map contains one or more hotspots, each of which specifies a set of pixels which may be non-contiguous and non-polygonal. The image map designer may create the image map using image processing software that facilitates creation of non-contiguous and non-polygonal image maps. Multiple versions of the image map may be created, each for use with a different magnification of the image. The image maps are stored in a compact format, which may be transmitted efficiently from a server to a client. Data contained within the image map facilitates the process of determining whether the client user's mouse pointer is within any of the hotspots, and the process of applying the image map to the image when rendered at different magnifications.

Abstract: A process for roughening a metal surface is provided comprising applying a coating to the metal surface wherein the coating is a temporary barrier to an etchant attacking the metal surface and the coating is susceptible to the etchant gradually removing the coating, and then etching the coated metal surface with an aqueous bath containing the etchant effective to produce a roughened metal surface.
