Patent CA-2291377-A1 (CA)
Title: System and method for locating mobile units operating within a wireless communication system
Inventor: VERDONK TIMOTHY C
IPC: H04W64/00
Filed: 1999-12-01
Abstract: A wireless communication system constructed according to the present invention interfaces with a Service Control Point (SCP) to provide location information for a serviced mobile unit. The SCP sends a locate request to a Home Location Register (HLR) of the wireless communication system, requesting the location of the serviced mobile unit. The HLR then accesses a serving Mobile Switching Center (MSC), the serving MSC being identified by the HLR as currently servicing the mobile unit. Depending upon the particular constraints of the requested operation by the SCP (e.g., immediate locate request or most recent locate request), the serving MSC either retrieves location information for the mobile unit from its Visitor Location Register (VLR) or sends a page to the mobile unit. The mobile unit responds to the page and, based upon the cell/sector from which the mobile unit responded, the serving MSC determines an approximate location of the mobile unit. With the location information retrieved, the serving MSC then converts the cell/sector identification to longitude and latitude information. The serving MSC may also convert a time-stamp associated with the location information (when the location information was recorded) to a normalized time standard such as Greenwich Standard Time. With this location information determined, the serving MSC provides the information to the requesting SCP. This information may be provided either directly by the serving MSC to the requesting SCP or may be provided via the HLR that receive the request. In converting the cell/sector identification in which the mobile unit was last located, the serving MSC (or other element of the wireless communication system that performs the conversion) provides the most likely location of the mobile unit within the cell/sector.

Patent CA-2298542-A1 (CA)
Title: A method of processing seismic data
Inventor: NICHOLS DAVID EDWARD
IPC: G01V1/28
Filed: 1998-08-12
Abstract: The invention relates to a method of processing seismic data that is less sensitive to the consequences of multiple propagation paths. There may be three paths (16, 18, 20) between a seismic source (S) and an image point (I).  Signals in paths (16 and 20) are refracted by salt bodies. If there were also three paths between a seismic receiver and the image point (I), there would be 9 possible permutations of outward and return signal paths for image point (I) and to account for all of these paths would be prohibitive. According to the present invention, the raypath resulting from the shortest outward and return paths is selected for subsequent processing (such as pre-stack depth migration etc.). The traveltime curves associated with the raypaths having shortest ray length are piecewise continuous and more likely to be associated with more of the energy than either the first arrival or the maximum amplitude arrival thus assisting in effective analysis of the seismic data.

Abstract: A public switched telephone system with an intelligent network (IN) for automated call processing is compatible with Call Waiting service. Unlike prior art systems in which a customer placing a call handled by an IN must disable Call Waiting service during an entire transaction (initial call placement, connection to the destination and conversation until the parties "hang up") to avoid non-processing or mis-processing by the IN, a customer using the present invention need only disable Call Waiting when communicating with an Intelligent Peripheral during the initial call placement. The system automatically restores Call Waiting after the call has been routed so that the feature is available during a telephone conversation.
Patent CA-2315577-A1 (CA)
Title: Adaptive gain and/or phase adjustment control system and method
Inventor: GHANADAN REZA
IPC: H04B3/06
Filed: 2000-08-04
Abstract: An adaptive gain and/or phase control system adapts the gain and/or phase adjustment resolution to provide improved performance. For example, the adaptive gain and/or phase control system can dynamically adjust the adjustment resolution for gain and/or phase adjustments as a function of the error signal(s). In response to a large error signals) (far from the null), the adaptive gain/or phase control system decreases the adjustment resolution, resulting in a faster convergence rate.  In a feed forward distortion reduction system, decreasing the adjustment resolution improves the transient response of the amplifier (for example, given any set of operating conditions, how quickly the amplifier responds to a changing input). As phase or gain adjustments are made to approach the null, the error signal reduces, and the adaptive distortion reduction system increases the adjustment resolution. By increasing the adjustment resolution as the error signal approaches the null, finer phase or gain adjustments can be made which further reduce the error signal.  For example, in a feed forward distortion reduction system, such a scheme prevents the error signal from repeatedly jumping over the null due to limited resolution without sacrificing the transient response of the amplifier.
Patent CA-2315583-A1 (CA)
Title: Alternating gain and phase control system and method
Inventor: GHANADAN REZA
IPC: H03F1/32
Filed: 2000-08-08
Abstract: A gain and phase control system performs a gain (or phase) adjustment based on the results of a previous gain (or phase) adjustment after an intervening phase (or gain) adjustment. A gain adjustment is based on the results of a previous gain adjustment rather than on the results of an intervening phase adjustment. A  phase adjustment is based on the results of a previous phase adjustment rather than the results of an intervening gain adjustment. As such, the above-mentioned increase in error signal does not occur because a gain adjustment is based on the results of the previous gain adjustment, and a phase adjustment is based on the results of the previous phase adjustments. In accordance with another aspect of the present invention, the gain and phase control system makes a gain (or phase) adjustment in parallel with detecting the results from a previous phase (or gain) adjustment, thereby taking advantage of the delay between adjustment and detection of the resulting error signal to improve the convergence rate. For example, the gain and phase control system can perform single alternating gain and phase adjustments and make a gain (or phase) adjustment while detecting the error signal resulting from a preceding phase (or gain) adjustment. When the error signal resulting from the gain (or phase) adjustment is being detected, the gain and phase control system makes a phase (or gain) adjustment using the results detected from the preceding phase (or gain) adjustment.

Filed: 2000-08-18
Abstract: A system for determining coverage in a wireless communications systems uses location information for a wireless unit and collects information on communications between the wireless unit and the wireless communications system in association with the location information. The wireless communications system determines and/or receives location information for the wireless unit along with other information associated with the location information. The information by location can be used to represent the coverage of a geographic region. For example, during communications between a serving base station and a wireless unit, the serving base station could receive and/or determine signal quality measurements of a forward link and/or of a reverse link at a particular location. Additionally, neighboring base stations can monitor the communications and determine and/or receive location information for the location of the wireless unit along with the information associated with or corresponding to the location of the wireless unit. The associated information can be linked with additional parameters, such as wireless unit type, wireless unit identity, frequency, operating conditions and/or base station identity. In accordance with other aspects of the present invention, the information and/or measurements stored by location can be used to derive additional and/or different information by location or determine how the wireless communications system communicates with a wireless unit at a location, for example the base station to service the wireless unit at the location. A wireless unit in a location or range of location(s) could be served by a serving base station(s) at a certain transmit power and frequencies given certain operating conditions or parameters, such as time, weather, traffic load, path loss and/or interference level. A change in operating condition could trigger a dynamic change in the RF coverage provided by the serving base station(s) and/or neighboring base stations to the wireless unit(s) in the location or range of locations.
