Title: Fiabilite de trous de connexion et diagnostic par sonde a faisceau electronique
Inventor: CAMPBELL MICHAEL
IPC: G01R31/319
Filed: 2001-06-21
Abstract: Selon l'invention, des dispositifs électroniques, tels que des dispositifs de circuits intégrés, sont testés par détermination d'une maille de défaillance à l'intérieur du dispositif électronique, qui provoque une défaillance du dispositif. Après identification de la maille de défaillance, on applique une contrainte locale à la maille de défaillance. La contrainte est appliquée de façon que seule la maille testée soit soumise à la contrainte, et que les mailles restantes et les composants du dispositif ne soient pas soumis à la contrainte. On observe un changement dans un signal produit par la maille de défaillance lorsque cette maille est soumise à la contrainte. Tester de cette façon permet d'aider à identifier la maille de défaillance comme source de défaillance du dispositif.

Title: Enhanced trim resolution voltage-controlled dimming led driver
Inventor: GUTHRIE DON W
IPC: H01L25/16
Filed: 2001-09-10
Abstract: Illumination sources (106a-106b), each including at least one light emitting  diode L1-l4, are connected either in series or in parallel by a switching circuit (108), depending upon an applied input voltage. The switching circui t (108) switches the illumination sources from series- to parallel-connection,  or vice versa, when the applied input voltage crosses a threshold value in traversing the operating range of applied input voltages. Because the light emitting diodes L1-L4 within the illumination sources (106a-106b) are switch ed from series to parallel connection at a defined kickover point (202b), the voltage-luminance characteristic (202) changes on opposite sides of the kickover point (202b). The resulting overall voltage-luminance characteristi c (202) has greater variability in luminance across the entire operating range  of applied input voltages, and luminance-variance is not limited to only a portion of the operating range.

Patent CA-2425085-A1 (CA)
Inventor: WOODS BILL
IPC: B65G67/06
Filed: 2003-03-31
Abstract: My invention called the "Producer Car Spout" (PCS) is a grain auger attachment used for loading producer cars. It is temporarily fastened to the discharge end of a farmer's grain auger. (Refer to Figure PCS-1) When grain is discharged from the auger, the PCS guides it through telescoping pipes into a railroad hopper car. The essence of my invention is: The grain auger and the railcar remain stationary during the entire railcar loading. Tests have shown that grain will flow freely through a sloping pipe provided the pipe's inclined surface makes an angle of elevation greater than forty degrees. The PCS has been designed with sufficient length and must be attached to an auger of sufficient height above the railcar to accommodate this minimum slope. The PCS is attached to the grain auger with a special support ring that also provides the means for the spout to flex in any desired vertical plane. A system of external rollers has been incorporated into the telescoping pipes to enhance the telescopic action. The PCS has a walking beam at its lower end with four flanged wheels for guiding the spout along the railcar opening. The PCS improves the ease and efficiency of loading because it eliminates the need to repeatedly reposition the grain auger and the grain truck. Utilizing the PCS, the farmer can redirect the grain flow to any desired compartment. The PCS is designed for easy removal so the grain auger can be used for its other farm purposes. When removed, the PCS is best stored in a vertical position for more convenient reattachment.

Title: Isolation of binding proteins with high affinity to ligands
Inventor: GEORGIOU GEORGE
IPC: C12N15/10
Filed: 2001-10-26
Abstract: The invention overcomes the deficiencies of the prior art by providing a rapid approach for isolating binding proteins capable of binding small molecules and peptides via "display-less" library screening. In the technique, libraries of candidate binding proteins, such as antibody sequences, are expressed in soluble form in the periplasmic space of gram negative bacteria, such as Escherichia coli, and are mixed with a labeled ligand. In clones expressing recombinant polypeptides with affinity for the ligand, the concentration of the labeled ligand bound to the binding protein is increased and allows the cells to be isolated from the rest of the library. Where fluorescent labeling of the target ligand is used, cells may be isolated by fluorescence activated cell sorting (FACS). The approach is more rapid than prior art methods and avoids problems associated with the surface-expression of ligand fusion proteins employed with phage display.

Title: System and method for integrated analysis of data for characterizing carbohydrate polymers
Inventor: ORON ASSAF
IPC: G01N33/15
Filed: 2001-11-05
Abstract: A system and method for characterizing carbohydrate polymers according to maps obtained from experimental data. Preferably, the data is obtained from a plurality of different types of experimental assays for characterizing the carbohydrate polymer. More preferably, at least one such assay involves binding a saccharide-binding agent to the carbohydrate polymer. One or more features of the carbohydrate polymer are then preferably characterized. These features are preferably derived from maps of the data obtained from assays involving the sample carbohydrate polymer. These maps are more preferably analyzed at a plurality of levels, with each level providing more abstract biological information. Most preferably, new types of experimental data are introduced to the process of analysis at each level, in order to support more complex analyses of the data. Optionally and most preferably, maps are eliminated at each level as being inconsistent with the experimental data. New maps are most preferably added at a higher level only if they are derived from the new experimental data which has been introduced at that level, in order to prevent a combinatorial explosion at successive levels of data analysis.
