Title: Optical dispersion compensation
Inventor: MOELLER LOTHAR BENEDICT ERHARD
IPC: H04B10/2507
Filed: 1998-09-28
Granted: 2003-05-13
Abstract: The present invention relates generally to the field of optical communications and particularly to optical communication techniques which compensate for dispersionsuch as that in optical fibers.   Compensation of optical dispersion is achieved with a polarisation beam splitter with first, second and third ports, a dispersion compensation fiber, a first return means that changes the mode of polarisation of a returned signal and a second return means. One end of the dispersion compensation means is connected to the third port of the polarisation beam splitter, the other end is connected to the first return means. The second return means is connected with the second port of the polarisation beam splitter, while the first port of the polarisation beam splitter forms input and output. As the signal passes through the disperion compensating fiber four times, the length of the dispersion compensating fiber can be greatly reduced.

Abstract: Pipe cleaning apparatuses for oil and gas pipelines are disclosed, in which a shield with a cleaning device is moved forward through a stream of liquid in the pipeline. The shield forms one or several passages for a passing stream of liquid within the pipeline in order to build up a desired pressure and is provided on its rear side with braking means which prevent the speed of advancement from rising to an undesirable extend in that at least one clamping element momentarily adheres to the pipe wall and moves relative to the braking means. This movement is kinematically transmitted to a hydraulic displacer which generates a secondary stream of liquid which is braked through at least one throttle and thus determines the speed between shield and pipe wall.

Title: Syringe pump
Inventor: TRIBE ROBERT JAMES
IPC: H03M1/30
Filed: 2000-04-27
Granted: 2008-04-01
Abstract: Conventional syringe pumps have a sensor mechanism to measure the size of the barrel of the syringe. In the present invention, an arm is swung against the barrel and coupled to a strip mask having a row of transparent apertures of differing length. The mask extends above a CCD array of sensing elements and below a concave mirror, which produces a collimated beam of radiation on the mask from an LED. The length of sensing elements exposed to radiation through an aperture in the mask gives an approximate indication of barrel size; the position of an edge of the aperture gives an accurate indication. The pump compares the barrel size with information relating size to syringe type and produces an indication of syringe type on a display.

Title: Mass spectrometry from surfaces
Inventor: ANDRIEN BRUCE A JR
IPC: H01J49/16
Filed: 1999-01-22
Granted: 2004-12-14
Abstract: A Time-Of-Flight mass spectrometer (1) is configured with a pulsing region (10) and electronic controls to cause the directing of ions to a surface (12) in the Time-Of-Flight pulsing region (10). The population of ions resulting from the collecting of said ions on or near said surface (12) is subsequently accelerated into the Time-Of-Flight tube (17) for mass to charge analysis. Ions produced away from said surface (12) can be directed to the surface (12) with high or low surface collisional energies. Higher energy ion collisions with the surface (12) can result in Surface Induced Dissociation fragmentation and the resulting ion fragment population can be mass analyzed. Mass analysis can be performed prior to directing the ions to the surface allowing MS/MS Time-Of-Flight mass analysis with SID. Ion to surface low energy collisions or soft landings resulting in little or no ion fragmentation provide a means for spatially focusing ions on or near the surface prior to accelerating the surface collected ions into the Time-Of-Flight tube.

Abstract: Ce dispositif d'imagerie/lecture à main de symboles codés est pourvu de moyens d'éclairement lumineux diffus, "fond noir" (90) et "fond clair" (162, 164), ces éclairages étant projetés sur des symboles placés sur une cible (partie d'un composant, marchandises, emballages, etc.). Cet imageur/lecteur (30) loge dans un boîtier ergonomique pouvant être pris en main de plusieurs façons, ce qui permet de l'immobiliser facilement. Les symboles à imager (40, 42, 44) sont ciblés par une ligne qui, non seulement localise les symboles, mais également qui, en tirant une longueur correspondant à celle des symboles, indique que ceux-ci sont dans le champ de vision de l'imageur/lecteur. On commande l'affichage du dispositif CCD (252), positionné pour recevoir la lumière réfléchie par les symboles, de manière que seules les parties sélectionnées du CCD soient à analyser à des fins d'éclairement et de mise au point. Afin d'optimiser les délais d'imagerie et de décodage, ainsi que pour optimiser l'utilisation de l'énergie, on procède à l'affichage de certaines parties du CCD de façon relativement rapide, en accélérant l'affichage du CCD dans certaines zones de sa région active, tout en revenant à un affichage plus lent pour des données à analyser à des fins de commande d'éclairement, de mise au point et de décodage. La mise en application, de surcroît, de principes d'entropie, facilite la détermination de la mise au point et des conditions d'éclairement optimales de l'imageur/lecteur.
