Patent CA-2442869-A1 (CA)
Inventor: PHELAN TIMOTHY
IPC: G06F17/30
Filed: 2002-03-29
Abstract: A method and system for coordinating access to a distributed database system, such as a financial services system database pool containing various sources of different types of data, receives as input a user query, such as a query related to the status of financial transactions. The query is processed to determine the types of data required to satisfy the query and the target data sources containing such data. Discrete sub-queries are formulated and issued to the identified target data sources. The retrieved data is combined to generate a response to the query which is formatted and returned to the requestor, preferably in the form of an Internet web page.

Title: Improved brominated polystyrenic resins
Inventor: LIN HOMER C
IPC: C08F8/20
Filed: 2002-03-05
Abstract: Novel brominated styrenic polymers having superior properties rendering them ideally suited for current commercial requirements for use as flame retardants in thermoplastic polymers are described. These properties include such high thermal stabilities in a standard Thermal Stability Test as to dramatically reduce if not eliminate the possibility of corrosion problems due to release of hydrogen halide at elevated polymer processing temperatures. Other special properties of the novel brominated styrenic polymers include, for example, low color or staining properties, and excellent melt flow characteristics.
Patent CA-2446341-A1 (CA)
Inventor: TOTTEWITZ MICHAEL
IPC: B01D29/62
Filed: 2002-05-02
Abstract: L'invention vise à réaliser des prélèvements d'échantillons d'eaux usées, notamment pour l'analyse photométrique. A cet effet, une quantité de filtrat est aspirée au travers d'une natte de filtrage (5), et une quantité d'échantillon est prélevée dans ce filtrat et soumise à une analyse. La natte de filtrage (5) est rincée de façon intermittente entre les phases de prélèvement de l'échantillon. Ladite natte de filtrage conduit par ailleurs le courant et reçoit lors de processus de rinçage intermittents un potentiel électrique positif en tant qu'anode pour la mise en oeuvre d'une oxydation anodique, tandis qu'une cathode séparée (22, 34) reçoit un potentiel électrique négatif. La quantité de filtrat est aspirée dans une chambre de filtrage (2) au travers de la natte de filtrage (5) par création d'une dépression. Cette dépression est essentiellement supprimée avant et/ou pendant le prélèvement de l'échantillon dans la chambre de filtrage (2).

Title: Apparatus and method for handling electronic mail
Inventor: WANG BING
IPC: G06F13/00
Filed: 2002-06-27
Abstract: A mail transfer agent adapted for determining the disposition of incoming e-mail from a sender includes a penalty count filter module (20) which functions on the basis of current communication system resource usage, such as the number of concurrent TCP connections being maintained, and penalty counts assigned for cumulative undesirable sender activity such as sending large e-mail files. The penalty count filter module can operate in a selective-rejection state accepting e-mail from senders without a penalty count and randomly accepting other e-mail, and in a random-rejection state rejecting all e-mail from senders with a penalty count and randomly rejecting other e-mail.  The rejection rates can be increased or decreased in response to a detected increase or decrease in the usage of system resources.

Patent CA-2471800-A1 (CA)
Inventor: MAKI MELVIN C
IPC: G08B13/24
Filed: 2004-06-21
Abstract: An intrusion detection system provides the function of an "active" ranging sensor cable system utilized for identification of the location of the intruder, with that of a "passive" cable detection system, in an integrated cable configuration. This dual function is provided with a single conventional sensing cable optimized for both "active" and "passive" sensing, or in combination with other parallel sensing cables for a "passive" cable component. The "active" cable component includes a coaxial sensor cable having a loosely disposed conductor. A signal is injected into the sensor cable such that a reflection is altered when an intrusion disturbs the cable. Based on the timing of the reflection, a processor, or a reflectometer, identifies the location of the disturbance. The "passive" cable component can be sensitized to detect intrusion via some other sensing phenomenology, such as the triboelectric effect, for triboelectric effect sensing.

Title: Chemical proteomics
Inventor: TOLEDO-SHERMAN LETICIA M
IPC: G01N33/68
Filed: 2003-01-28
Abstract: The invention relates to methods and reagents for identifying/isolating protein targets of chemical compounds (for example, drug candidates) using mass spectrometry. The invention provides a method for capturing and identifying proteins using tethered small-molecule probes. This technology also allows the market expansion of known drugs by finding new therapeutic targets; identification of the mechanism of toxicity of drug candidates or drugs which failed in the clinic; identification of new chemical tools for chemically-driven target validation; identification of new drug leads; and identification of the mechanism of action of drugs and drug candidates. A key advantage of the technology is that a single experiment can identify the numerous proteins which interact with a probe (or "bait").
