Title: Apparatus, methods, computer program products for generating a runway field clearance floor envelope about a selected runway
Inventor: JOHNSON STEVEN C
IPC: G08B21/18
Filed: 2001-01-04
Abstract: The present invention provides apparatus, methods, and computer program products that monitor the altitude of an aircraft with respect to a selected runway. If the altitude of the aircraft is below a minimum glideslope with respect to the selected runway, the apparatus, methods, and computer program products of the present invention alert the flight crew, such that the altitude of the aircraft can be increased.      This, in turn, increases time for reaction to abrupt changes in elevation near the selected runway. Specifically, the apparatus, methods, and computer program products of the present invention define a runway field clearance floor envelope about the selected runway that represents different preselected altitudes above the selected runway at respective distances from the selected runway. The apparatus, method, and computer program products of the present invention compare the altitude of the aircraft with respect to the selected runway to the runway filed clearance floor envelope. If the altitude of the aircraft is less than the minimum altitude of the aircraft is less than the minimum altitude indicated for the aircraft at the given distance, the apparatus, method, and computer program products of the present invention provide an indication to the flight crew. Since the runway field clearance floor envelope is constructed relative to the runway by defining minimum altitude values that should be maintained relative to the elevation of the runway, the indications generated to the flight crew should provide a desired reaction time for the flight crew to adjust the aircraft to abrupt changes in elevation at or near a selected runway.

IPC: H04W88/18
Filed: 1999-05-24
Abstract: A method for storing transaction data for an application in a wireless messages system. Applications can be used to allow paging messages to be entered into a wireless messaging system from external systems such as E-mail or the World Wide Web. Such applications may be implemented on an external application platform that includes the hardware system and system software required by the application. Applications have often required the use of certain type of transaction data stored in an application database designed specifically for the system. The present invention provides a method for storing such transaction data in a database inside the wireless system (19), through the use of a code library (17) that allows the application to send special networking messages to the wireless system. In a hybrid system, the application may still have its own transaction database (18) in which to store some types of data but may store other types of data in a database in the wireless infrastructure. The applications' transaction database in these hybrid systems is simpler to design than those that store all the transaction data for the application.
Patent CA-2337598-A1 (CA)
Inventor: SPECTOR MAGALY
IPC: H04B10/2557
Filed: 2001-02-19
Abstract: A facility is provided to enhance the simultaneous transmission of optical signals of different data rates, for example, OC48 and OC192 signals. Specifically, a first stream of channels carrying signals of different data rates and a second stream of channels carrying signals each having the same data rate are supplied to respective inputs of an asymmetric wavelength combiner, which interleaves the streams at an output for transmission over an optical path. Advantageously the combiner inherently reshapes the signals that it processes, which makes it ideally suited to offset cladding mode problems encountered when demultiplexing and multiplexing the signal streams.

Title: Temporary selective national roaming at predetermined network operation conditions in a mobile radio communication system
Inventor: SALMINEN REIJO
IPC: H04Q7/36
Filed: 1999-07-29
Abstract: The invention relates to a method, an exchange, a telecommunica-tion system and a mobile station for providing a temporary selective national roaming at predetermined network operation conditions, e.g.  at network overload in a mobile radio communication system. A first switching means (MSC/VLR) of a home network (HPLMN) performs a negotiation with a second switching means (MSC/VLR') of another network (VPLMN) which has free capacity to handle mobile stations (MS1-MS4) of the first network (HPLMN) which cannot be handled by said first network (HPLMN) during e.g. an overload condition occurring therein. When e.g. the overload condition occurs, a request message (RM) is first sent to the second switching means (MSC/VLR') in order to enquire whether the second network (VPLMN) has enough free ca-pacity to take over mobile stations (MS2-MS4) from the first network (HPLMN). Thus, it can be ensured that mobile stations (MS1-MS4) of the first network (HPLMN) do not cause an overload condition in the second network (VPLMN) when they have been registered in the second network (VPLMN) and receive a service therein.
