Abstract: A multi lumen catheter assembly. The assembly provides an expandable, low profile, fixed length sheath and catheter, with fixed infusion ports. The assembly has an expandable outer sheath that expands upon pressure activation with a fluid and the sheath allows the fluid to exit from at least one predetermined fixed location from a distal end of the catheter assembly. The catheter assembly can be used in various medical device procedures, such as a TIPS (Transjugular Intrahepatic Portosystemic Shunt) procedure, or anywhere a low profile, multi lumen, infusion catheter system is desired.

Abstract: To achieve a substantially uniform microstructure across a continuously cast thin metal strip, it is beneficial to cool a width of the strip to a substantially constant temperature before further cooling the strip to reach any desired phase transformation temperature. Accordingly, methods of continuously casting a thin metal strip may include moving the thin strip to a cooling section, the cooling section having a plurality of coolant discharge ports configured to discharge a flow of coolant along the thin strip; initially sensing the temperature of the thin strip to determine a temperature distribution across the width of the thin strip, and producing a sensor signal corresponding to a sensed temperature at each of the first plurality of locations; and individually controlling the cooling across a width of the thin strip by way of the plurality coolant discharge ports in each zone of a first row using the determined temperature distribution.

Abstract: Systems and techniques for predicting customer response to content and selecting content for delivery to particular customers in accordance with the predictions. As information is delivered to and received from a plurality of customers over multiple communication channels, data streams representing communications between providers and customers are analyzed and selected data extracted therefrom. Linkages are created between data collected from the different channels and data are anonymized. The data are analyzed to create a customer response predictor for each customer that models customer behavior and predicts customer response to advertisements. As content, such as advertisements, are to be delivered to a destination, information from a predictor created using data collected from a customer associated with the destination is used to select appropriate content.

A first party is authorized by a product support service provider to receive product support services by request of login identification and passwords. The first party is provided with tokens to purchase and authorized to allocate the tokens to any other party at its discretion. The tokens are accepted by the support service provider in exchange for support services.

Abstract: A method of making printed circuit boards in a continuous process. The method uses copper base metal sputtered onto a substrate. This base metal is much thinner than the base metal normally used in printed circuit processes and ultimately allows a greater number of conductors per unit of length to be made on the boards.
