Title: An improved method for an authentication of a user subscription identity module
Inventor: MARCOVICI MICHAEL
IPC: G06F21/34

Granted: 2006-05-30
Abstract: A method for improving an established Authentication and Key Agreement procedure which prevents rogue mobiles from fraudulently gaining access to a communication system. The communication system periodically broadcasts a challenge interrogation message requesting that a mobile, which is currently validated to use the system, to authenticate itself to the system. The mobile computes an authentication response based on information known only to the communication system and the USIM of the mobile and transmits said response to the communication system. The communication system also computes an authentication response and compares said response with that received from the mobile. A  mobile is authenticated by the communication system when the two authentication responses are equal.      Otherwise, the mobile is not given access to the communication system.

Patent CA-2362511-C (CA)
Inventor: KLOSTERMANN RAINER
IPC: C08G85/00
Filed: 2000-02-10
Granted: 2008-05-06
Abstract: The invention relates to a method for on-line monitoring and controlling the monomer conversion during emulsion polymerization. According to said method, a balance is continuously made, starting from an initialization point in time, of the heat amount Q IN fed to a reaction, the reaction enthalpy Q RE added by the supply with monomers and the amount of heat Q OUT dissipated from the reactor. A non-dissipated amount of heat Q AD is calculated on the basis of these value s which in the case of a spontaneous adiabatic reaction would result in an increase in the internal temperature and the internal pressure of the reactor. A check is carried out whether the potential adiabatic temperatures and pressures are always within the predetermined upper limits. If said upper limits are exceeded, the addition of monomers to the reactor is slowed down or stopped.

Abstract: Point-to-point protocol (PPP) negotiation in a wireless communication system between e.g. a mobile station (MS) and a packet data service node (PDSN). The MS sends to the PDSN a link control protocol option designated option X that identifies a user profile including at least one pre-negotiated PPP parameter.  If the PDSN supports the user profile and the at least one parameter, it acknowledges this. In response, the MS acknowledges its acceptance. Then each node sets a state machine in accordance with the user profile. If the PDSN  supports the user profile but not one or more of the at least one parameter, it sends a negative-acknowledgment identifying a second, acceptable user profile. If the PDSN does not support the user profile, it rejects the first user profile and a full PPP negotiation is performed without reference to any of the pre-stored user profiles.

Abstract: A method for measuring the amount of fluid contained in a reaction vessel in a clinical analyzer includes the steps of adding a first aliquot of fluid to the reaction vessel and measuring the quantity of fluid contained therein. A second aliquot of fluid is then added to the reaction vessel and the quantity of fluid contained therein is also measured. Measurement of the two fluid quantities can occur with or without removal of the first aliquot in between measurements. In obtaining the two quantity measurements and comparing them against a standard, the effects of well geometry can be minimized. Preferably, a delta or ratio measurement is obtained between the first and second liquid volume measurements which can be compared against a standard so as to normalize apparent volume losses or gains due to reaction well dimensional variation. This approach enhances the analytical capability to detect true fluid delivery errors.
