Patent CA-2299317-A1 (CA)
Inventor: HASSAN AMER A
IPC: H04L1/00
Filed: 1998-08-13
Abstract: Selon cette invention, une séquence source de symboles est communiquée par l'intermédiaire d'un support de communication grâce au codage de cette séquence source conformément à de premier et second codes de correction d'erreurs et ce, en vue de produire une première et une seconde séquences codées de symboles. Ces première et seconde séquences codées sont traitées en vue de produire un signal de communication qui est ensuite communiqué par l'intermédiaire dudit support de communication. Ce signal de communication communiqué est traité dans le but de produire une première et une seconde séquences de symboles reçues correspondant respectivement aux première et seconde séquences codées. Ces première et seconde séquences reçues sont décodées de manière sélective et récursive conformément aux codes de correction d'erreurs associés et aux estimations préalables d'un symbole de la séquence source et ce, aux fins de produire de manière répétée des estimations révisées du symbole, jusqu'à obtenir une estimation satisfaisant à des critères de fiabilité prédéterminés. Ces première et seconde séquences reçues peuvent être décodées de manière sélective et récursive grâce, d'une part, au décodage à probabilité maximale de la première séquence reçue, en vue de produire une première estimation d'un symbole de la séquence source et une métrique de chemin associée à cette première estimation; et, d'autre part, au décodage de la seconde séquence reçue, en vue de produire une seconde estimation du premier symbole si une fonction prédéterminée de la métrique de chemin associée à la première estimation se trouve en dehors d'une plage prédéterminée. De même, les séquences reçues peuvent être décodées de manière sélective grâce, d'une part, au décodage maximal a posteriori (MAP) de la première séquence reçue, en vue de produire une première estimation MAP d'un symbole de la séquence source et une métrique de fiabilité associée à cette première estimation; et, d'autre part, au décodage de la seconde séquence reçue, en vue de produire une seconde estimation du premier symbole si la métrique de fiabilité associée à la première estimation MAP se trouve en dehors d'une plage prédéterminée. Le codage de la séquence source conformément aux premier et second codes de correction d'erreurs peut être précédé du codage de la séquence source conformément à un code de détection d'erreurs, par exemple, un code de redondance cyclique (CRC). Un décodage récursif sélectif peut comprendre le décodage d'une première séquence reçue conformément au premier code de correction d'erreurs, en vue de produire une estimation d'un symbole de la séquence source, puis le décodage de cette estimation conformément au code de détection d'erreurs en vue de produire la métrique de fiabilité concernant cette estimation.

Patent CA-2315168-A1 (CA)
Inventor: RAJI ALEXANDER D
IPC: H04M1/57
Filed: 1998-11-19
Abstract: A method for notifying an internet browser user of an incoming telephone call is performed by internet call notification software residing on the user's computer and software residing within a telephone network. A user selects the location of the internet notification software as a home page for the browser. The home page prompts the user for activation of internet call notification. If the user requests internet call notification, the software transmits an internet protocol address to the telephone network. The network then stores the internet protocol address for the user. When a call is made to the user, the telephone network accesses a database to retrieve the stored internet protocol address. The network then transmits a message to the user's software to notify the user of the incoming call. The software displays a window containing information about the telephone call. If the user chooses to accept the call, the software closes the browser and connects the telephone call to the user.

Patent CA-2326132-A1 (CA)
Inventor: ANDERSON DEWEY CHARLES
IPC: H04Q3/64
Filed: 1999-03-03
Abstract: Determining a desired listing begins by creating a definition for each listing without regard to predefined boundaries, such as political boundaries. The coverage area may be defined by default depending upon a categorization of its listing. The coverage area may also be defined as a selectable area depending upon selection criteria, such as payment of a fee. A reference point may be determined based upon information provided about the reference point. The location of the reference point may be determined from the information. A  search region is typically selected based upon a proximity of the search region to the reference point. Coverage areas intersecting the search region are then found. These intersecting coverage areas are typically ranked into a ranked order. The ranked order may be based upon the amount of intersecting area for each intersecting coverage area or may be based upon the proximity of the intersecting coverage area to the reference point. A listing is identified as the desired listing typically based upon the ranked order of the intersecting coverage areas. Finally, an identification of the desired listing may be distributed.
