Abstract: A bobbin for use in a three-phase line reactor. The bobbin includes a tubular main body with a first end, a second end, a first side, a second side, and a core that extends from the first end to the second end. The main body also has two radially-extending flanges; one on its first end and another on its second end. Four tabs extend axially from the main body and are integral with it. A first tab is positioned on the first end of the main body extending from the first side and a second tab is positioned opposite the first tab on the second side. A third tab is positioned on the second end of the main body extending from the first side and a fourth tab is positioned opposite the third tab on the second side. The integral tabs eliminate the need for metal support bars used to hold and align laminations inserted into the cores of the bobbins. Thus, fixing laminations in place is more accurate and repeatable than with prior bobbins. Further, since the tabs may be sized and shaped exactly, precise alignment of the components of a three phase reactor is possible. The bobbin may include ridged sidewalls which enhance the strength of the bobbin. The ridges may also be designed to enhance camber control and spacing of the wire coil wound on the bobbin.

Abstract: A device works as an emergency shut off for a valve having an open and a closed position with a lever for manually moving the valve from one of the positions to the other. The device has a mounting locus in fixed position relative to the valve, a tension member having a first end, a second end and an intermediate portion therebetween, the first end being affixed to the lever and the intermediate portion passing through the mounting locus;  a sleeve member slidingly fitted along the tension member, the sleeve member having a first spring retainer firmly fixed thereto along its length and a second spring retainer slidingly received on the sleeve member and coupled thereto by a portion of a releasable adhesive agent;  a helical spring for biasing, mounted along an external surface of the sleeve member in a longitudinally compressed manner between the first and second spring retainers; and a first cable stop affixed to the tension member, the sleeve member being constrained between the mounting locus and the first cable stop. When a release agent, such as heat, decouples the second spring retainer from the sleeve member by releasing the releasable adhesive agent, such as a solder, the spring restores to an uncompressed length, effectively moving the first and second spring retainers apart and translating the tension member a sufficient amount to move the valve from one position to the other position. In addition to this automatic action of the device, the valve may be manually moved from one position to the other by a pull on the tension member.

Title: Signal-to-noise monitoring in wdm optical communication systems
Inventor: ALEXANDER STEPHEN B
IPC: H04B10/08
Filed: 1998-05-29
Granted: 2008-10-21
Abstract: The present invention provides an optical monitoring system for a WDM optical communication system. In an exemplary embodiment, the monitoring system includes a wavelength selecting device which receives a WDM optical communication signal comprising plural optical channels and optical noise (e.g., ASE). The wavelength selecting device separately outputs optical signals corresponding to each of the optical channels and at least one optical noise sample taken at a wavelength which is not occupied by one of the optical channels. At least one optical power motor optically communicates with the wavelength selecting device for measuring the optical power of each of the optical channels and the optical noise sample. The optical power meter outputs an electrical signal indicating the strength of a measured optical channel or of the optical noise sample. A data analyzer, such as an microprocessor, receives the electrical signals output by the power meter and calculates the optical noise at the wavelengths of each of the N optical channels based upon the measured noise sample. Using the calculated optical noise values, the data analyzer determines the signal to noise ratio of each optical channel. Advantageously, the technique of the present invention uses a minimum of power measurements to accurately determine the signal-to-noise ratios of the optical channels.

Abstract: An adaptive gain and/or phase control system adapts the gain and/or phase adjustment resolution to provide improved performance. For example, the adaptive gain and/or phase control system can dynamically adjust the adjustment resolution for gain and/or phase adjustments as a function of the error signal(s). In response to a large error signals) (far from the null), the adaptive gain/or phase control system decreases the adjustment resolution, resulting in a faster convergence rate.  In a feed forward distortion reduction system, decreasing the adjustment resolution improves the transient response of the amplifier (for example, given any set of operating conditions, how quickly the amplifier responds to a changing input). As phase or gain adjustments are made to approach the null, the error signal reduces, and the adaptive distortion reduction system increases the adjustment resolution. By increasing the adjustment resolution as the error signal approaches the null, finer phase or gain adjustments can be made which further reduce the error signal.  For example, in a feed forward distortion reduction system, such a scheme prevents the error signal from repeatedly jumping over the null due to limited resolution without sacrificing the transient response of the amplifier.

Le procédé consiste à mesurer une pluralité de valeurs de gain optique générées par une pluralité d'unités d'amplification de fibre optique disposées dans des trajets de bouclage parcourant les premier et second trajets de transmission du système de communication optique. Une signature de gain est obtenue par soustraction d'une pluralité de valeurs de base de la pluralité de valeurs de gain optique. Les modifications de l'état directionnel sont appliquées le long de la signature de gain pour identifier une pluralité d'états directionnels. A chaque état est affecté un état prédéfini de telle sorte que la signature de gain soit représentée par une séquence d'états prédéfinis. Cette séquence est comparée à une pluralité de séquences prédéterminées d'états prédéfinis, chacune correspondant à une panne connue. Au moins une correspondance exacte est identifiée entre la séquence d'états prédéfinis de la signature de gain et les séquences prédéterminées. La séquence prédéterminée de correspondance identifie la panne provoquant une signature de gain.
