Patent CA-2422222-A1 (CA)
Inventor: NG BENJAMIN KOON KEI
IPC: H04J11/00
Filed: 2003-03-14
Abstract: The present invention provides a new multiple access scheme, called the spread space spectrum multiple access scheme (SSSMA), designed for the forward link in a wireless multi-antenna system serving multiple users, who may have different quality of service requirements such as data rate and error probability. In the multi-antenna system where the SSSMA is employed, the base station transmitter and the receivers at the users' terminals all employ multiple antenna elements. By exploiting the multiple antennas which are deployed at the base station and each user's terminal, the objectives of the SSSMA are two folds: (1) increase the number of user-channels available in the system, (2) increase the individual user's data rate and improve the link performance such that each user's service requirement is satisfied.

Title: Method of logging a borehole
Inventor: SAMWORTH JAMES ROGER
IPC: E21B47/12
Filed: 2003-09-10
Abstract: In the field of wellbore data logging it is known to use isotopic neutron sources in a neutron capture logging technique. However, continuous isotopic sources are unpopular for regulatory and safety reasons.        Attempts to employ neutron generator tubes to generate neutron bursts for use in the neutron capture technique have encountered various difficulties in areas connected with signal identification and processing.     The disclosure relates to a method of data logging in which a low burst rate neutron generator tube is pulsed at comparatively low rates to generate neutron bursts that are captured in atomic nuclei in a proximal formation.        The gamma radiation arising from the neutron capture is detected over a gating intervals defined by temporally distinct points. The gamma detector output is integrated over the gating interval to provide a measure of the decay rate that is independent of the pulse rate. Consequently the signal processing problems do not arise.

Inventor: ANDERSON PERRY
IPC: A61H33/02
Filed: 2003-10-10
Abstract: A method and device for controlling the intensity of flow of water leaving a single speed water pump and entering a spa tub. A single speed water pump is connected to a spa tub via a pump suction pipe and a pump outlet pipe. The single speed water pump has its suction connected to the spa tub and sucks water out of the spa tub via the pump suction pipe. A controller is electrically connected to at least one air valve and the air valve is connected to the pump suction pipe. The controller opens the air valve to allow air into the pump suction. Air from the air valve mixes with water pumped from the tub to create an air/water mixture. The air water mixture is pumped back into the spa tub via the pump outlet pipe. The intensity of the flow of the air water mixture back into the spa tub depends upon the amount of air allowed into the air/water mixture via the air valve. Preferably, the controller is programmed with programming instructions to vary the intensity of the flow of the air/water mixture back into the spa tub. Also, several air valves may be utilized to provide a range of air flows.
