Abstract: A process is disclosed for preparing low molecular weight homomacromers and comacromets. The process of preparing a homomacromer comprises the steps of: (a) charging a reactor with (i) a single ethylenically unsaturated monomer selected from the group consisting of acrylic monomers or monoalkenyl aromatic monomers and (ii) if said ethylenically unsaturated monomer is not a thermally initiating monomer, a free radical polymerizable initiator, to form a polymerizable reaction charge; and (b) heating the reaction charge during continuous mixing in the reactor to a reaction temperature in the range from about 180 °C to about 500 °C for a residence time greater than 5 minutes to form the low molecular weight homomacromers, provided that if the residence time is 60 minutes or less that the reaction temperature is greater than 270 °C. The comacromers are prepared by charging the reactor with (i) at least two ethylenically unsaturated monomers selected from the group consisting of acrylic monomers, monoalkenyl aromatic monomers or mixtures thereof and (ii) if at least one of said ethylenically unsaturated monomers is not a thermally initiating monomer, a free radical polymerization initiator, and heating the reactor to a reactor temperature in the range from about 180 °C to about 500 °C for a residence time greater than 5 minutes to form the low molecular weight comacromers, provided that if the residence time is 60 minutes or less that the reaction temperature is greater than 270 ° C and further provided that if the reaction charge is a mixture of acrylic monomer and monoalkenyl monomer and the residence time is 60 minutes or less then the reaction temperature is greater than 310 °C.

Abstract: One aspect of the invention is to provide novel genetic constructions for the expression of inhibitory RNA in the cytoplasm of eukaryotic cells. The inhibitory RNA may be an anti-sense RNA or a co-suppressor RNA. The genetic constructions of the invention are capable of replicating in the cytoplasm of a eukaryotic cell and comprise a promoter region in functional combination with an encoding polynucleotide.      The genetic constructions may be designed so as to replicate in the cytoplasm of plant cells, yeast cells, and mammalian cells.     When the eukaryotic cell of interest is a plant cell, the genetic construction is preferably derived from a plant RNA virus.      Plant RNA virus derived generic constructions , may employ a plant virus subgenomic promoter, including subgenomic promoters from tobamoviruses in functional combination with the RNA encoding region. Another aspect of the invention is to provide cells comprising the genetic constructions of the invention and organism comprising a plurality of such cells. Another aspect of the invention is to provide methods of reducing the expression of a gene of interest in eukaryotic cells, i.e., methods of producing eukaryotic cells exhibiting reduced levels of expression of a gene of interest. The methods of the invention comprise the step of transfecting a cell with a genetic construction of the invention in which the RNA encoding region is specific for the gene of interest. Another aspect of the invention is to provide plant cells that produce elevated levels of the carotenoid phytoene. The elevated levels of phytoene are achieved by inhibiting the expression at the enzyme phytoene desaturase using the vectors of the invention.

Abstract: Cette invention visant à pondérer les dérangements occasionnés lors d'une mise à jour de logiciel porte sur une technique de copie d'état pour système informatique comportant au moins deux partitions logiques. Dans le cadre de cette technique, un état d'un nouveau logiciel dans une partition de réserve (6, 16) est amené à l'état d'un ancien logiciel dans une partition d'exécution (16, 6) alors que se poursuit l'exécution de cet ancien logiciel. Le transfert de données de la partition d'exécution vers la partition de réserve s'effectue de façon échelonnée et, dès que l'on est parvenu au même état dans la partition de réserve (6, 16) et la partition d'exécution (16, 6), l'exécution bascule vers le nouveau logiciel. Cette technique permet de pondérer les dérangements occasionnés par la mise à jour d'un logiciel pour les ramener à un niveau jugé convenable.

Abstract: Logical coverage areas are dynamically rearranged to meet the traffic needs of a wireless switching system. Further, the logical coverage areas do not have to be initially provisioned during deployment of the wireless switching system since the initial determination of the logical coverage areas is automatically performed. Once the logical coverage areas are established, the logical coverage areas adapt to the changing needs of the community of wireless handsets. A first embodiment allows the base stations to control the rearrangements, and a second embodiment allows a system wireless controller controlling the wireless switching system to control the rearrangements.

Title: Multi-valve injection/aspiration manifold
Inventor: FEITH RAYMOND P
IPC: A61M39/02
Filed: 1999-06-18
Granted: 2005-11-29
Abstract: A IV manifold (18) includes a plurality of injection/aspiration ports (27, 3 0, 32), and has an elongate configuration with a width greater than the diameter of the ports. A flow channel (49) is formed between mating members (22, 24) of a housing (23) and provided with a U-shaped configuration (90). Projections (50, 52, 54) along the flow channel direct fluid flow into valve cavities (63, 65, 67) associated with t he ports to clear dead spots around the valve elements (30, 32, 34). A check valve (26) included in the manifold tends to create direct high-pressure against the valve elements which respond by forming a surface seal thereby avoiding deformation. An aspiratio n port can be formed with a second seal disposed on the side of the valve element opposite the first seal. Opening this second seal by negative pressure in the lumen o f the port provides for the aspiration of fluids in the flow channel. Two-way aspiratio n can be provided by a valve having a cage with or without compressible characteristics to accommodate low tolerance fittings.

Title: Feedback technique for wireless systems with multiple transmit and receive antennas
Inventor: CHUNG SEONG-TAEK
IPC: H04B7/005
Filed: 2001-11-09
Granted: 2011-07-26
Abstract: In a wireless communication system using multiple antennas at the transmitter and multiple antennas at the receiver, a so called multiple-input multiple- output (MIMO) system, a substantial improvement in capacity over the case of no feedback can be achieved using considerably less bandwidth than is required to feedback the channel estimate or channel statistics, by supplying as feedback for each data substream of an overall data stream an indicator of a rate and/or an indicator of a gain for transmission of that data substream. The indicator of the rate and/or the indicator of the gain may be the rate and/or gain directly or an encoded representation of the rate and/or gain. Typically, the best performance is achieved if indicators of both the rate and the gain are fed back. If the invention is implemented for wireless systems, then typically for each data substream there is a separate, independent antenna. The rate and the gain are computed as a function of a channel estimate which is developed at the receiver. Advantageously, the transmitter may employ only one- dimensional data coding for each of the data substreams.

Abstract: A method for enhancing vision of an eye includes a laser delivery system having a laser beam for ablating corneal material from the cornea of the eye.  Measurements are made to determine an optical path difference between a plane wave and a wavefront emanating from the retina of the eye for a location at a surface of the cornea. An optical correction is provided to the laser delivery system for the location based on the optical path difference and refractive indices of media through which the wavefront passes. The optical correction includes dividing the optical path difference by a difference between an index of refraction of corneal material and an index of refraction of air. The laser beam is directed to the location on the surface of the cornea and corneal material ablated at the location in response to the optical correction to cause the wavefront to approximate the shape of the plane wave at that location.
