20100193485 | METHODS AND SYSTEMS FOR LASER CUTTING AND PROCESSING TUBING TO MAKE MEDICAL DEVICES - Methods for making devices include providing a tubular member to be formed into a device, placing a removable sacrificial block material in the lumen of the tubular member and laser cutting the tubular member. A doping material can be added to the melted portion of the tubular member to promote the formation of brittle slag. A fixture can be used to hold a cut workpiece in order to ream sacrificial material from the surface of the workpiece. Pressurized gas can be supplied to the inner lumen of the tubular member to cause slag to form on the outside surface, rather than the inner surface, of the tubular member. A tubular member made from nickel-titanium alloy can be tightly adhered to a sacrificial sleeve utilizing the phase changes associated with nickel-titanium. A rotating mandrel can be placed within the lumen of the tubular member during laser cutting. A mandrel which includes an enlarged diameter section causes the workpiece to expand slightly within its elastic deformation range to dislodge islands from the workpiece. Such a mandrel could be formed from a tubular member which has a central lumen that can be used to deliver a pressurized medium to “blast” islands from the workpiece. | 08-05-2010 |
20110119287 | AUTOMATIC REUSE OF USER-SPECIFIED CONTENT IN QUERIES - A device and method for reusing user-specified content is provided. After generation of a query comprising parameters explicitly set by the user, the explicitly set parameters are stored in a parameter store. If a subsequent query is generated without any explicitly set parameters, the stored parameters are automatically applied to the subsequent query, and the modified query is then transmitted to an online service, such as an e-commerce site or search engine. User query preference history may be stored for use in modifying a subsequent theory. In addition, the user may navigate to specially designated content on a page, and when the content is in focus, the user may optionally copy the content for reuse in generating a further query or for publication. | 05-19-2011 |
