Abstract: A user may discover and navigate among hyperlinks through the use of a keyboard. For example, a user may press a tab key to discover and navigate to a first hyperlink that is part of a hypertext document. The first hyperlink is, in response, given focus and a focus shape is drawn around the text or graphics for the hot region of the hyperlink. If the user again presses the tab key, the next hyperlink is given focus and a focus shape (i.e., an outline that surrounds the next hyperlink) is drawn around the next hyperlink. A user may also tab to a placeholder for an image in order to make a decision whether the image should be downloaded or not.

Abstract: The invention relates to a method and an apparatus for encoding images, more particularly to an encoding unit in conjunction with a library of pictorial entities and image qualifiers. The method and apparatus provide encoding an image by using a code factor table in conjunction with a set of element codes. The resulting image code allows the set pictorial elements of an image and their associated image, qualifiers to be represented by a compact code uniquely representing a given configuration of pictorial elements. The use of the resulting image code facilitates the transmission and storage of images requiring only the code to be sent or stored. The invention further provides a computer readable medium comprising a program element that direct a computer to implement the encoding process.

Abstract: Disclosed is the method for creating a reinforced hollow fiber membrane by applying reinforcing filaments to a core, casting a dope over the filaments and core, forming a membrane from the dope, and removing the core. The core may be a moving core, and the reinforcing yarns may comprise warp yarns and a spiral wrap yarn. The core may be soluble and removed by dissolving it. The core may be pre-wrapped with a yarn before the warp yarns are applied. The resulting reinforcing cage may be pre-shrunk before it is coated with a membrane dope. The pre-wrapped yarn may be removed, for example by dissolving it, after the reinforcing cage is coated. A precursor assembly for making a hollow fiber membrane is also provided.
