Title: Frequency selective predistortion in a linear transmitter
Inventor: LYENDECKER ROBERT R
IPC: H03F1/32
Filed: 1998-05-05
Abstract: A system for linearly transmitting an amplified output signal using predistortion is disclosed. The system uses a straight inverse modeling scheme to more easily and accurately determine the inverse of the distortion caused by a power amplifier (1002) of a RF transmitter. The direct inverse modeling scheme of the present invention indexes the LUT (1020) using the modulated input signals instead of the potentially noisier output signals, which helps to increase the accuracy of the predistortion. The predistorter system (1010) stores complex coefficients in the LUT (1020), which are then used as the tap weights of a digital filter implementing the predistorter (1022). Finally, the trainer (1008) uses a modified version of the power amplifier (1002) output signal. The modified power amplifier (1002) output signal has the in-band distortion removed from the power amplifier (1002) output signal.

IPC: H04J13/00
Filed: 2000-01-05
Abstract: A method for allocating traffic between multiple carriers in a wireless communications system measures loading on the communication system and selects an appropriate carrier from multiple carriers, based upon the loading measured. A first carrier is selected if the load on the first carrier is lower than or equal to the lowest loading of any supplemental carrier among the multiple carriers. If the load on the first carrier is not lower, then the subscriber may be assigned either to a supplemental carrier or the first carrier. The carrier assignment of the subscriber depends upon a predetermined threshold, which preferably considers actual or estimated differential interference between the first carrier and the supplemental carrier.
Patent CA-2294816-A1 (CA)
Inventor: TWERDOCHLIB MICHAEL
IPC: G01K11/10
Filed: 1998-07-01
Abstract: This invention includes a detection system that can determine if a turbine component, such as a turbine vane or blade, has exceeded a critical temperature, such as a melting point, along any point along the entire surface of the vane or blade. This system can be employed in a conventional combustion turbine having a compressor, a combustor and a turbine section. Included within this system is a chemical coating disposed along the entire interior surface of a vane or blade and a closed loop cooling system that circulates a coolant through the interior of the vane or blade. If the temperature of the vane or blade exceeds a critical temperature, the chemical coating will be expelled from the vane or blade into the coolant. Since while traversing the closed loop cooling system the coolant passes through a detector, the presence of the chemical coating in the coolant will be sensed by the system. If the chemical coating is detected, this indicates that the vane or blade has exceeded a critical temperature.

Title: Method for manufacturing reduced iron agglomerates and apparatus therefor
Inventor: HARADA TAKAO
IPC: C21B11/08
Filed: 2000-01-12
Abstract: A method for manufacturing reduced iron agglomerates comprises the steps of supplying iron oxide agglomerates including carbonaceous material on a moving hearth, heating and reducing the agglomerates to yield reduced iron agglomerates while the moving hearth moves in the reduction furnace, discharging the reduced iron agglomerates from the reduction furnace, recovering the reduced iron agglomerates, and removing seized hearth fragments separated from the moving hearth in close proximity to a discharge location or a recovery location for the reduced iron while the reduction furnace is being operated. According to the method, the reduction furnace can be operated for a long period of time without stopping the operation thereof and supply of the iron oxide agglomerates. Consequently, high productivity of the reduced iron agglomerates can be achieved, and in addition, superior quality in high degree of metallization of the reduced iron agglomerates can be obtained since the seized hearth fragments having low degree of metallization are not mixed with the reduced iron agglomerates as a product.

Patent CA-2298085-A1 (CA)
Title: Edge detection and seam tracking with emats
Inventor: MACLAUCHLAN DANIEL T
IPC: G01N29/24
Filed: 2000-02-03
Abstract: A method for detecting the location of an edge, interface, seam or other structure of a workpiece uses one or two electromagnetic acoustic transducers (EMATs) to transmit an ultrasonic wave along the workpiece toward the edge and to receive a reflected wave. The velocity of the wave in the material is used in conjunction with the round trip time-of flight (TOF) of the transmitted and reflected wave, to calculate the location of the edge. This is done by placing the transducer or transducers at known locations on the workpiece. A surface wave or 90 degree shear wave can be utilized and no contact is needed between the transducer and the surface of the workpiece. Rough and/or dirty surfaces and hostile environments can be accommodated while practicing the invention.

Filed: 1998-10-07
Abstract: L'isomère 3.alpha. de RTI-55 et de RTI-352 est un ligand efficace en matière de fixation in vivo qui fait montre d'une plus grande sélectivité à l'égard du transporteur de la dopamine que celle observée concernant RTI-55. On note, de surcroît, une mise en place plus rapide de l'équilibre apparent du rapport striatal/cérébelleux (en comparaison de RTI-55), les crêtes de rapport survenant au bout de 30 minutes environ et se maintenant pendant environ 20 minutes. Cet équilibre apparent se révèle utile dans la mise en place des modalités d'évaluation du nombre de transporteurs de la dopamine présents dans les tissus. Ces résultats indiquent, de surcroît, que l'emploi d'isomères 3.alpha. d'une variété de tropanes 3.beta. (à substitution phényle) débouche sur un renforcement de la sélectivité à l'égard des transporteurs de la dopamine ainsi que sur une mise en place plus rapide de l'équilibre apparent.

Title: Steam pre-heating in oriented strand board production
Inventor: PALARDY ROBERT D
IPC: B32B21/13
Filed: 1998-11-09
Abstract: Oriented strand board (10) is produced using a continuous belt press (22) and using an isocyanate binder with steam exposure of the mat (18) of wood material prior to entry into the press. The steam exposure provides moisture which softens wood fibers and enhances lignin flow in the mat. In addition, the moisture reacts with isocyanate binder to produce polyureas from the isocyanate binder (e.g. the preferred binder is pMDI); thereby reducing the cure conditions (i.e.  temperature, pressure and time) required for the press to fuse the mat and binder together. The isocyanate binder also reacts with hydroxyl groups in the cellulose and hemicellulose strands of the wood material to allow both chemical and physical bonds to be created with the wood material. The oriented strand board exiting the press has a higher moisture content and more resistant thickness swell under humid conditions.
