Title: System and method for enhanced navigation
Inventor: FLYNN MALIA C
IPC: H04N5/445
Filed: 2000-12-15
Abstract: Navigation techniques enable Internet web pages and other image frames to be navigated using a conventional keyboard (28) or a television remote control (30), for example. In a first technique, a guide mapping application (23) links objects in the various frames contained in an accessed web page so that when a user actuates a directional button on a remote control (30) or a keyboard (28), the guide mapping application (23) navigates the user to an object in the present frame or in another frame to which a currently selected object is linked. The guide mapping application (23) also employs "edge of frame" indicators in those objects which are located on an edge of a frame.  When an "edge of frame" indicator is detected, the application searches for and locates the appropriate adjacent frame, as well as the object within the adjacent frame that is located in the closest proximity to the object containing the "edge of frame" indicator, and then navigates the user to that object. A navigation application (31) is also preferably provided that detects when a user actuates a specified key or combination of keys, or holds down a specified key for a fixed period of time, for example, and changes the functionality of the key or keys from cursor navigation to mouse navigation to enable the user to navigate a web page as if they had a mouse input device.

Title: Catheter balloon forming process
Inventor: ZHANG MICHAEL Y
IPC: B29C67/00
Filed: 2001-01-11
Abstract: The present invention is directed to apparatus and method for forming balloons with improved dimensional stability and balloons formed by the same. The method of the present invention provides for a very accurate control of the temperature profile of the balloon material during its making. The attributes of the balloon can be affected by how the balloon is treated during the blowing stage and after the initial blowing, i.e., heat-setting. Using the present method, the balloon will form more uniformly and evenly (e.g., wall thickness and outer diameter of the balloon). The present method significantly increases the dimensional stability of the balloon which provides a balloon that is more predictable in use. The present heat-set process also provides the means for the working length to be located more accurately on dilation catheters and stent delivery systems.
