IPC: C12Q1/68
Filed: 2003-04-08
Abstract: L'invention concerne un procédé de fabrication et d'utilisation d'une puce de dosage comportant une région hydrophile bordée par une région hydrophobe. Cette configuration est souhaitable en ce qu'elle permet à l'usager de déposer des réactifs présents dans un milieu aqueux sur la région hydrophile pendant que la région hydrophobe empêche les réactifs de s'écouler hors de la région hydrophile. Ainsi, les réactifs peuvent être isolés dans la région hydrophile afin de réduire au minimum toute perte ou dilution des réactifs. Dans un mode de réalisation préféré, la surface de la puce présente plusieurs régions hydrophiles bordées par des régions hydrophobes, ce qui permet à l'usager d'effectuer plusieurs dosages sur la même puce sans contamination croisée des échantillons. Le dispositif présente un intérêt particulier dans le champ de l'analyse génétique, dans lequel des oligonucléotides sont fixés à une électrode dorée à des fins d'analyse électrochimique.

Title: Applying session services based on packet flows
Inventor: PROCTOR JAMES A JR
IPC: H04L12/56
Filed: 2003-06-09
Abstract: Session services are employed in a networked computing environment to apply specific processing to an exchange of data between processes. In a wireless communication network, a single wireless link (28) is typically shared among multiple users (P1-P3) through wireless channels, which are allocated and switched among the users on a demand basis. Packets sent over the wireless link (28) need to be signaled and tagged accordingly to initiate and employ the session service for the intended packets which comprise the flow (F1-F3).  A method for identifying and applying session services to a wireless link (28) includes identifying a packet flow (F1-F3) over the wireless link (28) corresponding to a received message by employing a flow identifier and filter.  The packet flow (F1-F3) corresponds to a session, and is mapped to at least one session service (30~). The mapped session service is then applied to the received message.

Title: System and method for heating a workpiece during a welding operation
Inventor: CHEN FUHU
IPC: B23K9/235
Filed: 2005-03-31
Abstract: A technique for heating a workpiece during welding is provided. The technique may comprise a heating system and a welding system. The heating system may be an induction heating system. The heating system is provided to heat the workpiece to a desired temperature and maintain the workpiece at the desired temperature as a weld joint is formed. Because the workpiece temperature is elevated, the difference in temperature between the filler material in the weld joint and the workpiece is reduced.  The reduction in the temperature difference between the filler material in the weld joint and the workpiece produces a lower rate of heat transfer from the filler material in the weld joint to the workpiece. The lower rate of heat transfer, in tum, produces a slower rate of temperature decrease in the weld joint.

Title: Improved dietary fiber containing materials comprising low molecular weight glucan
Inventor: HILBERT BRENT
IPC: A23L19/00
Filed: 2004-04-02
Abstract: A dietary fiber material obtained by using enzymes to digest cereal grains.  The enzymes substantially hydrolyze any starch occurring in the cereal grain into small molecules but only partially hydrolyze .szlig.-glucan molecules.  The dietary fiber material can have excellent physicochemical, physiological, and sensory properties such ass low molecular weight, a particular molecular weight distribution, and a particular polydispersity, in addition to having excellent food ingredient properties. As a food ingredient, the material can have high .szlig.-glucan content which provides nutrient to the body. Because the dietary fiber material can have neutral mouthfeel, it can be used to enhance the nutritional content of ice cream, yogurt, baked goods, bars, beverages, or certain other foods-without affecting the taste or other sensory attributes of the food. As a further benefit, the dietary fiber material can be used to provide certain therapeutic benefits, such as anticholesterol activity.
