Patent CA-2335898-A1 (CA)
Inventor: TAKAGI KAZUO
IPC: H04L1/00
Filed: 2001-02-13
Abstract: A storage circuit defines a first field for storing first header bits of a first payload signal of a first data unit, a second field, and a third field for storing the first payload signal. The first header bits are equal in number to second header bits of a second payload signal of a second data unit. A division circuit divides the first header bits by a generator polynomial to produce a first error check code. The same generator polynomial is used to divide the second header bits to produce a second error check code. A remainder of division of hypothetical header bits by the generator polynomial is summed to the first error check code to produce a sum which is inserted into the second field of the storage circuit. The hypothetical header bits are greater in number than a total number of bits in the first and second fields, so that the first and second data units can be distinguished from each other by different error check results of the first and second data units.

IPC: H04Q3/00
Filed: 1999-09-24
Abstract: The present invention relates generally to telecommunications, and more specifically to a method and system of providing telecommunication services that is flexible and efficient. Existing Public Switched Telephone Network systems suffer from a number of problems including system complexity, access being proprietary and services being implemented on fixed hardware. As a result, new services are complex and costly to develop, so telcos only provide services that appeal very broadly. The invention provides an open and flexible system by describing communications in terms of graph packets which contain pointers to blocks of software code, rather than containing large blocks of executable code. In the preferred embodiment, these graphs identify software filters which are dedicated to particular tasks, and are based on a standard API. This allows third parties to create new filters and make them available, allowing new services to be provided quickly and easily.

Patent CA-2347435-A1 (CA)
Inventor: GEISER PETER ANDERSON
IPC: G01V1/28
Filed: 1999-10-15
Abstract: An invention for the filtering, sorting and analysis of microseis-micity induced during production of fluid resources from their reservoirs which allows direct 4 dimensional measurements of all or many of the components of the permeability fields as well as other petrophysical rock properties important to reser-voir analysis and monitoring. The seismicity associated with the per-meability field is identified by its spatial and temporal location in two general conoidal volumes (12), sym-metrically disposed about the injec-tion point (14) in any well being used for this purpose. The seis-micity is generated by fractures hy-draulically linked to the injection well and comprises the permeabil-ity field associated with that well.  Mapping of the permeability field identified by this means can also be used for guiding the placement of subsequent infill, development and injection wells. In addition by per-mitting the active deformation field to be seen, it allows potential haz-ards to the field infrastructure to be recognized. By predicting the fluid paths, the invention forms an important adjunct to 4D active seismic analysis which monitors the migration of fluid fronts.

Abstract: A method and system for providing concatenative speech uses a speech synthesis input to populate a triphone-indexed database that is later used for searching and retrieval to create a phoneme string acceptable for a text-to-speech operation. Prior to initiating the "real lime" synthesis, a database is created of all possible triphone contexts by inputting a continuous stream of speech. The speech data is then analyzed to identify all possible triphone sequences in the stream, and the various units chosen for each context. During a later text-to-speech operation, the triphone contexts in the text are identified and the triphone-indexed phonemes in the database are searched to retrieve the best-matched candidates.

Title: System for real-time monitor and response
Inventor: GRINTER RICHARD C
IPC: G06F17/40
Filed: 2000-01-25
Abstract: A data and object monitoring and response system comprising a three tier infrastructure for optimization of interoperability and task specific adaptability. The system gathers information from a plurality of distributed data gathering units and assimilates, processes, analyzes and distributes the gathered data within a common system with rule based data processing for coordinated response to the data.  The data gathering units can be locally distributed or widely disbursed. The information gathered can be real-time collection of event data, historical data, systems monitoring, or other data. Regardless of the specific nature of the data, the system taught in the present invention, addresses a number of common problems associated with the collection, assimilation, processing of data. By dividing the system into a three tier interactive structure, the data can be gathered, evaluated and processed independently and efficiently and appropriate response can be effectively implemented. The processing tier, which includes the rules for analysis of the data, exists independent of the operator interface and data gathering tiers. A  wide diversity of data collection equipment can be accommodated without modification of the operator interface or the processing tier. Processing rules can be modified without altering the collection and handling of data, and a commonality of data structure eliminates multiple polling of collected data sets.
