Title: Procede de fabrication de fibres optiques
Inventor: BERKEY GEORGE E
IPC: G02B6/00
Filed: 1999-04-09
Abstract: L'invention concerne une fibre optique et un procédé de fabrication de celle-ci. Cette fibre présente des régions de diamètre différent alternées sur sa longueur. On choisit l'indice de réfraction de la préforme et les diamètres de la fibre de manière à obtenir une fibre présentant des sections à dispersion positive et négative à une longueur d'ondes supérieure à 1480 nm, mais dont la dispersion totale et la pente sont de préférence faibles. Une version préférée de ce type de profil comprend une région coeur entourée d'une région gaine. La région coeur est composée d'une région centrale dont le coefficient de dopage est plus élevé que celui de la gaine, ce coeur étant en outre entouré d'une région douve présentant un coefficient de dopage inférieur à celui de la gaine. La région douve est entourée d'une région annulaire présentant un coefficient de dopage supérieur à celui de la gaine.

Abstract: An optical fiber (50) has two or more cores (46, 48) with respective faces (54, 56) on the fiber's (50) ends. The faces (54, 56) are oriented so that optical radiation can be coupled into or out of the individual cores (46, 48) thereby permitting, for example, optical radiation from the various cores (46, 48) to be spatially resolved in the far field. The faces (54, 56) can be formed on the fiber (50) by polishing the fiber (50) at an angle with respect to the cores (46, 48), i.e, with respect to the optical paths traversed by the optical radiation passing through the fiber (50).

Abstract: A reliable data communications protocol for the broadcast of long messages over a noisy medium, such as a frequency hopping communications link with multiple interferors. Long length messages are divided into a plurality of subpackets, each of which incorporates an error detection mechanism. A message integrity field is calculated based upon the contents of the subpackets, and is stored within one of the plurality of subpackets. The subpackets are transmitted two or more times.  Each subpacket is stored by a recipient if received without error, and the recipient calculates a message integrity field based upon the stored subpackets. When the calculated message integrity field corresponds to the message integrity field received within the subpackets, the long message is deemed properly transmitted, reassembled from the plurality of subpackets, and processed appropriately.

Title: Dual compartment stand-up pouch
Inventor: BEER JEFFREY SCOTT
IPC: B65D75/00
Filed: 2001-02-09
Abstract: A dispensing package formed of a flexible material, e.g., a plastic film or laminate, and having two separate compartments for holding paste-like materials therein until they are to be dispensed together from the package. The package also includes an outlet in the form of a fitment having a removable cap coupled to the two compartments. The first compartment is formed by an outer panel of the package and one section of a gusset panel which forms a first. inner panel. The second compartment is formed by another outer panel of the package an another section of the gusset panel which forms a second inner panel. One outer panel and its immediately adjacent inner panel are secured together along their bottom marginal edges. The other outer panel and its immediately adjacent outer panel are welded together along their bottom marginal edges. All of the panels are also welded together along their side marginal edges to form the two compartments, with each compartment having a passageway at the top thereof in communication with the fitment. The fitment is coupled to the passageways of the compartments to enable the contents of the two compartments to be ejected, e.g., squeezed, out the fitment from the package together. The two compartments are juxtaposed with respect to each other, with the inner panels being disposed in a confronting relationship with each other but arranged to be spaced apart from each other, whereupon the bottom edge of the two compartment form a wide, stable base for supporting the package in an upright orientation.

Abstract: L'invention concerne un procédé de transmission de données numériques par un canal de transmission (2) affecté par des perturbations survenant en rafales. Dans un récepteur (3), un décodage (9) à décision flexible est réalisé après une démodulation (7) en tenant compte d'une qualité de signaux appréciée. Pour déterminer la qualité des signaux, on peut vérifier pour un nombre déterminé de symboles reçus s'ils se trouvent dans les limites d'une distance prédéterminée du point de constellation. Le nombre des symboles situés dans les limites de la distance prédéterminée peut être utilisé comme valeur de qualité lors du décodage suivant. Ainsi, on obtient une courbe (16.1 à 16.3) avec une bosse (17.1 à 17.3). En revanche, les symboles avec un faible niveau de bruit acoustique sont surévalués tandis que les symboles avec un niveau de bruit acoustique élevé sont sous-évalués.

Title: Slider link press
Inventor: FUJIMORI HIROMICHI
IPC: B30B1/06
Filed: 2001-07-16
Abstract: A slider link press includes an oscillation link operating about a fulcrum shaft and an eccentric crank pin. A connecting link connects the oscillation link to a slide. The oscillating link and fulcrum shaft act to increase press torque, reduce downward press speed, and increases upward press speed thereby maintaining cycle time. The eccentric crank pin operates the oscillation link, aids in torque increase, and provides reciprocating movement to the slide. The slide includes pivotable slide gibs that engage reciprocal fixed gibs to maintain parallel surface contact and absorb and eliminate eccentric loads on the slide and the press. Stays and spacers align sides of the press and eliminate flexing under load while absorbing and distributing deformation pressure.
