Patent CA-2275520-A1 (CA)
Title: Wireless transmission method for antenna arrays, having improved resistance to fading
Inventor: HOCHWALD BERTRAND M
IPC: H04L1/06
Filed: 1999-06-18
Abstract: Disclosed is a modulation method for wireless signal transmission. Each message that is transmitted is made up of a sequence of signals, each selected from a constellation of L such signals, L a positive integer. Each transmitted signal is distributed spatially across a transmitting antenna array, and is also distributed in time. Thus, each signal may be represented as a TxM matrix, in which each of the M columns represents a distinct antenna of the array, and each of the T rows represents a distinct time interval. Each entry in this matrix represents a complex baseband voltage amplitude. Each of these signal matrices is proportional to a matrix having orthonormal columns.

Title: Method for syntonizing the wave lengths of an arrangement of optoelectronic components
Inventor: HILLMER HARTMUT
IPC: H01S5/40
Filed: 1998-11-12
Abstract: The invention relates to a method for syntonizing an arrangement of optoelectronic components, said arrangement consisting of at least two optoelectronic components. The aim of the invention is to minimise the cost.     According to the inventive method, the characteristic wave length for each optoelectronic component is set by selectively adjusting the amount of resistance of the conductor of the resistance heating (H) or the amount of resistance of a resistance mechanism (RM) connected upstream of the resistance heating (H). The inventive method is suitable for syntonizing the wave lengths of semiconductor lasers, optical amplifiers, filters, wavelength multiplexers and wave guides.

Title: Burner for a heat generator
Inventor: HAFFNER KEN
IPC: F23D14/02
Filed: 1999-09-13
Abstract: In a burner for operating a combustor, the former consists essentially of a rotation generator (100), a transition piece following the rotation generator, and a mixing pipe following this transition piece. Transition piece and mixing pipe form the mixing section (220) of the burner and are located upstream from a combustion chamber (30).  In the lower part of the mixing pipe is located a pilot burner system (300) which creates, among other things, a stabilization of the flame front, in particular in the transient load ranges, while minimizing pollutant emissions. A sensor (400) installed in the burner detects a flashback of the flame (80), whereupon the fuel quantity of this flame is at least temporarily reduced and at the same time the fuel quantity for the pilot burner is increased in such a way that the total fuel quantity and thus the turbine output remains constant. This measure prevents a destruction of the burner.

Patent CA-2284339-A1 (CA)
Inventor: KOCHER HARTMUT
IPC: G06F9/46
Filed: 1999-10-01
Abstract: Instead of a conventional task scheduler in which tasks having a high priority are preferentially scheduled, so that the execution of tasks with very low priorities is blocked, a "fair scheduler" is proposed in which each task (TA to TE) is assigned a counter (CNT) and a threshold value (THD), with the threshold value specifying a maximum number of execute cycles within which the task need not be executed immediately, and the counter counting those execute cycles within which the task is not executed. At the beginning of each execute cycle, a test is made to determine whether one of the counters exceeds the associated threshold value. If that is the case, one (TD) of the corresponding tasks (TC, TD) is selected by a selection criterion and executed, and its counter is reset. The counters assigned to the remaining tasks are incremented by one, and the execute cycle is repeated if it is found that at least one more of the tasks (TC) is waiting to be processed.

IPC: C03B37/04
Filed: 1998-05-08
Abstract: Fine-grained aragonite precipitated calcium carbonate is produced on a commercial scale by seeding with a coarse-grained aragonite precipitated calcium carbonate. The coarse-grained seeding material is produced by interrupting, after the production of 0.1 to 0.6 g/L min. of calcium carbonate, the supply of carbon dioxide to the quicklime slurry early in the reaction to allow subsequent nucleation of the crystals and then continuing the supply of carbon dioxide at reaction rates of 0.1 g/L min. to 0.6 g/L min. This coarse-grained seeding material has a Blaine surface area which may be less than 30,000 cm2/g, the solids of which are 35 to 70 weight percent aragonite, and is added to subsequent batches as a slurry at about 1 weight percent, based on the total weight of the slurry of the material to be seeded. For the seeded batches, carbonation is carried out at reaction rates of up to 1.8 g/L min. at the commercial scale resulting in fine-grained aragonite product. This final seeded product need not be ground, has solids in which the weight percent of aragonite is greater than 90, has a median particle size between 0.30 to about 0.5 microns, a particle size distribution where about 60 to 70 weight percent are less than 0.5 micron equivalent spherical diameter, and a Blaine surface area which may be greater than 35,000 cm2/g.

Inventor: JOHANSSON JOERGEN
IPC: H04W8/06
Filed: 1998-08-21
Abstract: The present invention relates generally to the problem of positioning of a mobile station ("MS") in a Public Land Mobile Network ("PLMN"), and more particularly to the problem of establishing the most accurate estimate of the last known position of the mobile station when the mobile station has switched off or has left the coverage area of the network. An application first sends a request to a Mobile Positioning Centre, requesting position information for a particular subscriber. The MPC contacts the preferred Positioning Procedure, e.g. GPS, to obtain the positioning information. If this information is not available then the MPC contacts the HLR to get the last known positioning data. The HLR will try to retrieve the last known positioning data from the VLR and forward it to the MPC. If this is not available then the last known position stored in the HLR is forwarded to the MPC.
