Patent CA-2255845-A1 (CA)
Title: Method of and apparatus for interference rejection combining and downlink beamforming in a cellular radiocommunications system
Inventor: FORSSEN ULF
IPC: H04L1/06
Filed: 1997-05-27
Abstract: Recently, interference rejection combining techniques have been proposed which can increase significantly the performance of the uplink in C/I limited environments.      Another interesting property of the IRC techniques is that their C/I performance does not degrade as the correlation between the received signals increases. This feature of IRC techniques is exploited in the present invention to allow for a reduced spacing between the antennas. According to another aspect of the present invention, the performance of the downlink is improved using beamforming techniques to "steer" base station transmissions toward a desired mobile station.      In this way, the performance of the downlink is improved using beamforming techniques to a degree similar to that at which the uplink has been improved using IRC techniques.      This allows the system designer to more fully exploit the variations in system design associated with improving the uplink performance.

Title: Combination pre-paid and calling card
Inventor: DAVITT MICHAEL
IPC: H04M17/00
Filed: 1999-04-19
Abstract: Subscribers (12l-12n) may receive combined pre-paid and calling card service offered via a telecommunications network (20) by dialing a telephone number (32) of a platform (26) within the network. The platform stores account information for each subscriber, including a pre-paid balance amount and overflow treatment indicator. Upon receipt of a call, the platform verifies the subscriber's eligibility for service and provides the service while decrementing the subscriber's pre-paid balance. When the subscriber's pre-paid balance falls below a prescribed value, the platform determines whether the subscriber is entitled to automatic billing of continuing service costs or whether the subscriber must enter information to facilitate billing of such costs based on the overflow indicator. Thereafter, the platform effects continuing call treatment and billing for such continuing call treatment when effected billing in accordance with the overflow indicator.

Title: Removal of contaminants from gas streams in rayon production
Inventor: SPINK EDWARD F
IPC: D01F13/02
Filed: 1998-05-21
Abstract: Sulfurous gas streams comprising hydrogen sulfide and carbon disulfide, such as produced as a by-product of the rayon-forming process, are processed to recover the components in a useable form. The gas stream first is contacted with an aqueous sodium hydroxide to dissolve out hydrogen sulfide and some of the carbon disulfide. The dissolved carbon disulfide is driven off from the solution and condensed as a liquid concentrate. Carbon disulfide receiving in the gas stream is recovered, such as by condensation. The aqueous sodium sulfide solution which remains is concentrated and the pH is adjusted, as necessary, to a value at which the sodium sulfide is predominantly in the form of sodium bisulfide. The concentrated sodium bisulfide solution is capable of reuse in the rayon-forming process along with the liquid concentrate of carbon disulfide.

Title: Method for reporting measurement information in a mobile communications system
Inventor: BODIN STIG ROLAND
IPC: H04W36/00
Filed: 1998-06-02
Abstract: When a mobile terminal (12) first switches over from the idle mode (powered on and waiting to set up for a call) to the active mode (call connected), it starts sending measurement information to the network as soon as a dedicated traffic channel is assigned. In the preferred embodiment, the first measurement report is transferred to the network during the first available slow associated control channel period. That first report to the network contains data that the mobile terminal (12) obtained while it was waiting in the idle mode. During subsequent slow associated control channel periods, the mobile terminal (12) transfers measurement information to the network based on the data obtained in the active mode.

Title: Detection of damage to the rope sheath of a synthetic fiber rope
Inventor: DE ANGELIS CLAUDIO
IPC: D07B1/14
Filed: 2000-01-21
Abstract: For detection of damage to the rope sheath (8) of a sheathed synthetic fiber rope (1) at least one connection carrying signals is created in the rope sheath (8) surrounding the synthetic fiber rope (1), the sheath being either in one piece or formed from the individual surfaces of strands of a covering layer in which each strand has a sheath. If this connection, which is preferably a copper wire 6 wound round the rope 1, is interrupted, the rope sheath (8) has been damaged from outside. In one embodiment, several of these so- called breaking elements (6) form a surface surrounding the rope, with the result that even localized damage to the rope sheath is detected. A control device (11, 12, 13), (21) monitors the signal conductor, detects rope damage should it occur, and initiates suitable measures should they be necessary.
