Patent CA-2364618-C (CA)
Inventor: SOININEN JONNE
IPC: H04L29/06
Filed: 2000-03-08
Granted: 2008-05-13
Abstract: In an access network which supports a mobile IP  protocol, a very mobile MS  might perform several handovers between access nodes during a long session which may cause inefficient mobile IP routing. In the present invention, an access node, which is the target of a handover during an IP session, is arranged to check the optimal routing in respect of the mobile IP, too. For that purpose, the access node is aware of the most preferred mobility agent, normally the closest one, which should be used. In a handover situation the system, preferably the access node, checks (31, 32) whether there is a more preferred mobile IP mobility agent which should substitute for the current mobility agent of the IP session. If there is a more preferred mobility agent for that access node and the preferred mobility agent is not the same as the current mobility agent, the connection to the current mobility agent is closed (33), and a new connection to the preferred mobility agent of the respective access node is opened (34).

Abstract: There is provided a control system for an internal combustion engine, which is capable of properly controlling the amount of exhaust gas recirculation according to a degree of flow rate degradation of an exhaust gas recirculation system and at the same time suppressing progress of the flow rate degradation. The control system has an exhaust gas recirculation system including an exhaust gas recirculation passage for communicating between an exhaust passage and an intake passage, and an exhaust gas recirculation valve for controlling the rate of exhaust gas recirculation to the intake passage via the exhaust gas recirculation passage according to the operation amount of the valve. An ECU cuts off supply of fuel to the engine during deceleration of the engine. An intake pipe absolute pressure sensor detects pressure within the intake passage. Further, the ECU sets an upper limit of the operation amount of the exhaust gas recirculation valve according to a change in the pressure within the intake passage detected when the exhaust gas recirculation valve is opened and closed during the cut-off of fuel supply.

Title: Method of making carboxylated cellulose fibers and products of the method
Inventor: SU BING
IPC: D06M13/322
Filed: 2000-10-06
Granted: 2005-03-29
Abstract: The invention is directed to a method of making carboxylated cellulose fibers whose fiber strength and degree of polymerization is not significantly sacrificed. The method involves the use of cyclic nitroxide free radical compounds as a primary oxidant and a hypohalite salt as a secondary oxidant in an aqueous environment. Preferably the oxidized cellulose is then stabilized against D.P loss in alkaline environments and color reversion with a reducing agent such as sodium borohydride. Alternatively it may be treated with an oxidant such as sodium chlorite. The method results in a high percentage of carboxyl groups located at the fiber surface. The product is especially useful as a papermaking fiber where it contributes strength and has a higher attraction for cationic additives. The product is also useful as an additive to recycled fiber to increase strength. The method can be used to improve properties of either virgin or recycled fiber. It does not require high .alpha.-cellulose fiber but is suitable for regular market pulps.

Title: Device for measuring a volume of drug
Inventor: LAVI GILAD
IPC: A61M5/00
Filed: 2001-03-28
Granted: 2009-09-08
Abstract: Devices and methods are disclosed for drug delivery systems which involve taking up and controlling a predetermined volume of liquid drug from a liquid drug container (933) into a volume measurement chamber (950) in a first step, and then expelling the predetermined volume to the administration element such as an injection needle in a second step. The volume measurement chamber (950) may operate as a piston-and-cylinder construction in which a threaded engagement between a control knob (966) and a threaded piston rod (934) enables the piston to be progressively withdrawn to a predetermined extent. This determines the volume drug. Pushing the same control knob (966) uncouples the threads and reduces the piston (952) to be pushed forward by a spring (960) to pump the predetermined volume of drug out through the administration element (e.g. needle).

Granted: 2010-01-19
Abstract: A pressure gage adapted to provide a mechanical indication of a sensed pressure and to provide an electrical signal indicative of the sensed pressure. The pressure gage includes a housing having a first fluid pressure chamber, a second fluid pressure chamber, and flexible diaphragm separating the first fluid pressure chamber from the second fluid pressure chamber. A magnet is coupled to the diaphragm such that movement of the diaphragm causes a related movement of the magnet. A helix is located adjacent to the magnet and a pointer is attached to the helix for conjoint rotation with a helix about a rotational axis. A Hall effect sensor is also located adjacent the magnet. Movement of the magnet in response to movement of the diaphragm rotates the helix and the pointer to provide a mechanical indication of the pressure sensed by the diaphragm, and the movement of the magnet causes the Hall effect sensor to generate an electrical signal indicative of the pressure sensed by the diaphragm.
