Title: Method and apparatus for remote location, identification and/or control of motor vehicles
Inventor: MARTENS DANIEL
IPC: B60R25/04
Filed: 1999-12-10
Abstract: This invention is known as PCEL, an acronym derived from the descriptive name Police Chase ELiminator. The invention provides an RF means for isolating, identifying, locating, controlling the speed of, and stopping a particular motor vehicle. Police vehicles will have an on-board computer which will issue secure RF  signals to nearby traffic, causing vehicles receiving that signal to respond with their individual identifier code and physical description. Through a repeated polling process, the police computer will be able to isolate a single "target" vehicle, then either keep it under surveillance, make it slow down, or cause the vehicle's engine to stop on command. Controlling the speed and stopping of the engine will be accomplished through remote interruption of the vehicle's ignition system.
Patent CA-2292476-A1 (CA)
Title: Method for handling parallel transactions on telephone pre-paid accounts
Inventor: SWEDBERG KARL TAGE GOERAN VINC
IPC: H04W4/24
Filed: 1998-05-26
Abstract: A method (100) is disclosed such that when a call is being set up (104) from or to a mobile (or fixed) pre-paid subscriber, a portion of the value in the subscriber's pre-paid account is withdrawn (114, 120) to cover the cost of the call. Preferably, the amount withdrawn (114, 120) is large enough to cover the cost for a call of typical duration (e.g., 4 minutes). At call set up (104), for example, in an Intelligent Network (10), this amount is withdrawn (114, 120) from the account and allocated to the call being set up.      If this amount is not completely used up, the remainder is returned (146) to the pre-paid account. If, however, the allocated amount is depleted (124) before the call is completed, a second allocation or withdrawal from the account is requested for that call. If the value left in the account is large enough to cover the second withdrawal request, a second amount is withdrawn (114, 120) and allocated to cover the ongoing call. If needed, additional withdrawals (114, 120) can be made to cover the ongoing call until it is completed.      Once the call is completed (142), any remainder of the allocated amount is returned (146) to the pre-paid account. Consequently, a pre-paid subscriber can have a plurality of parallel ongoing calls, and because the amount in the pre-paid account is being monitored (116, 122) and accounted for before or while the calls occur, there is no risk that these calls will not be covered by the amount in the pre-paid account.

Title: Hitless reconfiguration of a wavelength division multiplexed optical communication network
Inventor: BALA KRISHNA
IPC: H04B10/27
Filed: 1997-12-23
Abstract: A method of reconfiguring a multi-wavelength communication network (Fig. 6).  The transition includes determining the union of the old and new topologies.  During at least the start of the transition, the network supports the union topology. New connections are connected according to the new topology, and the old topology, as its connections expire, is gradually removed. In allocating wavelengths to a new topology, two algorithms are developed which assign wavelengths which do not color clash with the wavelength assignments of the old topology.

Title: Mass spectrometer with method for real time removal of background signal
Inventor: COUSINS LISA
IPC: H01J49/26
Filed: 2000-02-24
Abstract: A mass spectrometer apparatus has one mass analyzer stage for selecting and rejecting ions having a particular mass-to-charge ratio and one fragmentation stage downstream from the first mass analysis stage for causing fragmentation of ions. Another mass analysis stage downstream from the fragmentation stage selects ions of a particular mass-to-charge ratio and rejects other ions. A synchronization unit is connected between the two mass analysis stages, for causing ions excited and removed in the one mass analysis stage to have the same mass-to-charge ratio as the ions selected by the other mass analysis stage, whereby ions detected by the detector are ions selected by the other mass analysis stage and generated by fragmentation in the fragmentation stage.

Patent CA-2303978-A1 (CA)
Inventor: QIN YUFEN
IPC: C12Q1/68
Filed: 1998-09-17
Abstract: The present invention relates to develop a series of B- and T-cell clonality assay kits. The data presented here has shown the importance of the B- and T-cell clonality assay kits in the early diagnosis and differential diagnosis for MS, PCNSL and other neurological diseases. In comparison to current diagnostic technologies (cytology, oligoclonal bands, CT, MRI, and surgical biopsy), the invented technology demonstrates its benefit as a technique which is high sensitive, specific, non-invasive, and economical, and which can be applied to different specimens (CSF cells, surgical biopsy and autopsy).  Utilization of this technology to MS study has shown that the B-cell clonal expansion is present in majority of MS patients, which have undergone antigen-driven somatic mutation in the germinal centers of peripheral lymphoid tissues. This finding implicates an important pathogenic pathway for the development of demyelination in CNS of MS. Furthermore, this technology allows the establishment of clonal specific RNA library from pathogenic cells in the CNS of the patients, which is important for further understanding of the role of antigen(s) in the cause of B-cell clonal expansion, and towards to developing antigen specific therapeutic strategy.
