Title: Method and apparatus for securely transmitting and authenticating biometric data over a network
Inventor: GLASS RANDAL
IPC: G07C9/00
Filed: 2000-01-17
Abstract: A method and apparatus for collecting and securely transmitting biometric data over a network contains a sensor, preferably a camera, for collecting biometric data and code generating hardware and software. The camera data is digitized and a unique code which is a function of the digitized camera data, a secret key and a transaction token is attached to the digital file. The code may identify the sensor which acquired the biometric information, a time at which the biometric information was acquired, or a time interval during which the data is considered to be valid, and a unique transaction code. The data and code are transmitted over a network to a server which authenticates that the data has not been altered by recomputing the code using its own knowledge of the secret key and transaction token needed to generate the code. If the data is authentic the server then computes a biometric template using the data. This biometric template is then compared to a previously defined biometric template to identify the user and give the user access to a secured resource. The system can be used for online banking and Internet commerce transactions.

Title: Coupled polymerase chain reaction-restriction endonuclease digestion-ligase detection reaction process
Inventor: BERGSTROM DONALD E
IPC: C12Q1/6853
Filed: 2000-03-17
Abstract: The present invention provides a method for identifying one or more low abundance sequences differing by one or more single-base changes, insertions , or deletions, from a high abundance sequence in a plurality of target nucleotide sequences. The high abundance wild-type sequence is selectively removed using high fidelity polymerase chain reaction analog conversion, facilitated by optimal buffer conditions, to create a restriction endonuclea se site in the high abundance wild-type gene, but not in the low abundance muta nt gene. This allows for digestion of the high abundance DNA. Subsequently the low abundant mutant DNA is amplified and detected by the ligase detection reaction assay. The present invention also relates to a kit for carrying out  this procedure.

Title: Mobile cellular radio system
Inventor: ALLAWAY ANDREW WAYNE
IPC: H04B7/185
Filed: 2000-08-10
Abstract: An interface (52) is provided between a satellite telephone system (4) and a cellular telephone system (5) for allowing calls to a user's cellular telephone to be diverted to a satellite telephone handset (25) when the user is unable to use his cellular telephone, for example when on board an aircraft (2) fitted with a satellite telephone system (20). The user inserts a card (which may be the SIM of his mobile phone, or a card compatible with existing satellite telephone equipment) into a suitable reader in the satellite telephone (20), which causes the satellite ground station's card verification system (42) to connect to a host cellular network (50). The host cellular network has an interface unit (520) which emulates the operation of a normal base station, so that the host cellular system (50) acts as if the mobile user's terminal is roaming on the host network, but is currently "busy". The interface (52) also resets the user's existing call diversion instructions so that when the host cellular system (5) receives a busy tone from the base station emulator (52), it routes calls to the directory number of the terminal (20). In order to allow the host network to retrieve the user's handset identity (IMSI), it makes use of a process by which data relating to a user having an identification code of a first type (the directory number) can be used to access a register in which identification codes of the first type are related to identification codes of the second type (the IMSI), and receiving from the register, in response to the signal, a code of the second type, so that location update information can then be transmitted to an associated switching system in respect of the identification code of the second type.

Abstract: A more efficient message notification system utilizing technology found in Instant Messaging Services. The more efficient system is achieved by first registering a Message Notification Application with an Instant Messaging Service. A user logs onto the Instant Messaging Service and indicates to the Message Notification Application that the user would like to be notified when new messages arrive. The Message Notification Application then adds the user to its own buddy list. The user is notified by the Message Notification Application through the Instant Messaging Service when a message is received. The user can then retrieve messages through an internet appliance with sound capabilities, or by utilizing the voice-to-text conversion capabilities of the application form the voice messaging or unified messaging server, or by more traditional methods such as a telephone.
Patent CA-2391149-A1 (CA)
Inventor: THIELMANN FRIEDOLIN
IPC: B23K5/00
Filed: 2002-06-21
Abstract: A cleaning system process and apparatus for welding torches performs the cleaning by subjecting the welding torch, including the weld tip, nozzle and gas diffusers, to cooling. The cooling provides a temperature shock sufficient to loosen the weld spatter from the torch. In one embodiment the loosened spatter may then be carried away from the torch by either or both of positive or negative fluid pressure, for example an air blast or a vacuum line, respectively. The cooling maybe done by subjecting the torch to a pressurized flow of coolant medium such as dry ice pellets or the like. The system may further cleanse the torch with an anti-spatter compound which can be applied by mixture with the coolant medium if desired. The cleaning system process is thorough, quick, subjects the torch to little stress, and improves performance of the nozzle including operation time between cleanings.
