Title: Apparatus for detecting raman gain in an optical transmission system
Inventor: DENKIN NATHAN MYRON
IPC: H04B10/29
Filed: 2001-04-23
Abstract: A unique sensor is used to detect a transmission impairment that may have affected incoming optical channel signals. The sensor, more specifically, selects a group of the incoming channel signals and generates a first power signal, P0, over the selected group of signals and generates a second power signals, P1, over a weighted version of the selected group of channel signals. The sensor then generates, as a function of the first and second power signals, P0 and P1, a signal indicative of whether the particular transmission impairment affected the levels of individual ones of the incoming channel signals. If so, then control apparatus offsets the impairment accordingly.

Title: Method and apparatus for fair and efficient scheduling of variable size data packets in input buffered switch
Inventor: AYBAY GUNES
IPC: H04L12/56
Filed: 1999-11-05
Abstract: An input-buffered multipoint switch having input channels and output channels includes multilevel request buffers, a data path multiplexer, and a scheduler. The switch has a distinct multilevel request buffer associated with each input channel and each request buffer has multiple request registers of a different request buffer priority. The request registers store data cell transfer requests that have been assigned quality of service (QoS) priorities, where the QoS priorities are related to packet source, destination, and/or application type. The multilevel request registers are linked in parallel to the scheduler to allow arbitration among requests of different input channels and different request buffer priority levels. The preferred arbitration process involves generating QoS priority-specific masks that reflect the output channels required by higher QoS priority requests and arbitrating among requests of the same QoS priority in QoS priority-specific multilevel schedulers. Sorting requests by QoS priority allows the switch to schedule a high throughput of packets while adhering to QoS requirements.

IPC: C08G63/80
Filed: 1999-11-25
Abstract: The present invention refers to the production of a polyester-type polymer and more particularly to the solid phase condensation of a polyester. The invention presents a process for manufacturing polyester which comprises at least the following steps: a) esterifying of transesterifying a carboxylic diacid or a carboxylic acid diester with a diol, b) prepolymerizing the esterification or transesterification product in liquid phase until an average degree of polymerization between 10 and 50, preferably between 20 and 45, c) preparing a dispersion of the prepolymer in a non-solvent of diol and non-swelling of the prepolymer liquid, the prepolymer being present in the dispersion in the form of solid particles having diameters under 2 mm and crystallized, with a crystalline lamella thickness under 17 nm, d) polymerizing in dispersed solid phase, e) recovering solid particles. The accomplishment of a dispersed solid phase polymerization permits improving the reaction kinetics. To obtain this improvement, the dispersed solid phase polymerization must be effected with a prepolymer having a particular degree of polymerization properties, of solid particle sizes and of crystalline qualities of the solid.

Inventor: DIERKS TIMOTHY
IPC: H04L9/32
Filed: 2001-09-20
Abstract: A certificate validity verification engine is integrated into the logic of a secure token, in turn, making the use of a private key conditional upon the determination that the certificate for the corresponding public key is valid at that particular instant in time. In this manner, the existence of a digital signature that is verified with a certificate implies that the certificate was valid at the time the signature was created. The verification of the certificate's validity by the relying party is unnecessary, as the signature could not have been created had the certificate been invalid. The validity of a certificate is communicated at the time the signature was created, rather than at the time the signature was verified.

Title: Liquefracture handpiece tip
Inventor: COHEN DONALD M
IPC: A61M1/00
Filed: 2001-10-04
Abstract: A surgical handpiece having two coaxially mounted tubes or channels mounted to a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to create an annular passage between the first and second tube. The annular gap communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular gap. The distal end of the annular gap is sealed by frictionally fitting together the distal ends of the first and second tube. One or more grooves formed in either the first or second tubes allow fluid being propelled down the annular gap to escape. A  stop may be provided against which the escaping fluid impinges such as by crimping the second tube near the distal end of the second tube.

Title: Short-circuit locator for printed circuit boards using a visible camera and an ir camera
Inventor: PASTOR MARC
IPC: H04N5/335
Filed: 2001-12-07
Abstract: A Printed Circuit Board (PCB), bare or populated with electronic components, may present some short-circuits occurring during the manufacturing or the assembly process. By taking different images of the entire PCB, at specific times, with an Infrared (IR) camera, before and after the short-circuit current is applied, and by processing them, it is possible to detect the warm pixels of the short-circuit fault on the PCB. The IR Focal Plan Array (FPA) of the camera, which is sensitive in the IR band, is able to sense and to detect a signal due to the heat radiation of the short-circuit area. Once this extra heat radiation has been detected for some identified pixels, these pixels are reported to the Visible image captured with a Visible camera in order to pin point the exact location of the short-circuit fault. Then, the fault can be corrected by the usual repair methods.

Title: Compositions and methods for the treatment of tumor
Inventor: WOOD WILLIAM I
IPC: C12N15/11
Filed: 2000-05-15
Abstract: The invention concerns compositions and methods for the diagnosis and treatment of neoplastic cell growth and proliferation in mammals, including humans. The invention is based upon the identification of genes that are amplified in the genome of tumor cells. Such gene amplification is expected to be associated with the overexpression of the gene product as compared to normal cells of the same tissue type and contribute to tumorigenesis.  Accordingly, the proteins encoded by the amplified genes are believed to be useful targets for the diagnosis and/or treatment (including prevention) of certain cancers, and may act as predictors of the prognosis of tumor treatment. The present invention is directed to novel polypeptides and to nucleic acid molecules encoding those polypeptides. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention.

Abstract: L'invention concerne un dispositif et un procédé de linéarisation d'un premier amplificateur possédant des caractéristiques non linéaires de réponse signal à un signal d'entrée. L'amplificateur est placé entre une source de signaux et une charge. A cet effet, on sélectionne un second amplificateur présentant des caractéristiques non linéaires de réponse signal à un signal d'entrée, similaires à celles du premier amplificateur. On envoie ensuite une partie du signal d'entrée en provenance de la source de signaux au second amplificateur en vue de générer un signal de sortie. On détermine la présence de différences entre le signal d'entrée et le signal de sortie, ce qui permet de fournir un signal de différence. Ce signal de différence subit une inversion de phase, puis le signal de différence à phase inversée est combiné au signal d'entrée, ce qui fournit un signal d'entrée corrigé. Ce signal corrigé est envoyé au premier amplificateur qui délivre alors un signal de sortie corrigé.
