Abstract: A wireless communication system (100) comprises a wireless infrastructure supporting communication for a plurality of mobile communication units (112-115). The wireless infrastructure comprises a processor (175) configured to generate a frequency re-use plan. The processor (175) generates a frequency re-use plan based on a relationship between one or more interference metrics, such as carrier to interference, and one or more quality of services for a plurality of communication types. In this manner, the inventive concepts support frequency planning for a radio system with multiple traffic types.  Furthermore, non-uniform allocation of penalties on different radio carriers in the same radio cell can be used. This allows different re-use distances to be achieved for different radio carriers. In so doing, it is now possible to plan for a different quality of service on individual radio carriers.

Abstract: An optically active composition (100) for optical applications has been identified. The optically active composition (100) can include at least one cyclic molecule having a nanocore (112) disposed within the cyclic molecule to form a filled ring (108). The composition (100) is optically transmissive for at least one photonic wavelength that would not otherwise be transmitted by the composition (100) if the nanocore were absent from the cyclic molecule.  The cyclic molecule can be a carbon ring, an aromatic ring, or a heterocyclic ring. The filled ring (108) can be attached to a chiral molecule which is a repeat unit (102) in a polymeric backbone. A second filled ring (110) which causes the composition to be optically transmissive at a second wavelength also can be attached to the chiral molecule (102) as well. An electric field can be applied to the filled ring (108) to adjust the wavelength at which filled ring (108) is transmissive.

Title: Suspensions de vehicules
Inventor: WESTNEDGE ANDREW
IPC: B60G11/04
Filed: 2006-09-05
Granted: 2014-01-28
Abstract: L'invention traite de systèmes de suspension pour véhicules ayant un bras longitudinal et d'un siège pour fixer le bras longitudinal à essieu ou à un carter de pont. Les bras longitudinaux sont placés sur des essieux ou carters de pont et tenus en place avec des boulons en U qui fixent le bras longitudinal à l'axe. Sous les charges excessives qui peuvent être appliquées aux systèmes de suspension pour véhicules, les bras longitudinaux peuvent être désalignés au détriment du fonctionnement du véhicule. Pour éviter ce désalignement, les sièges pour les bras longitudinaux peuvent être soudés aux essieux ou carters des véhicules et les bras longitudinaux sont fixés avec des fixations telles que des boulons en U. Ici, les tolérances de fabrication peuvent causer un mauvais raccord relativement lâche entre le siège et l'essieu ou le carter de pond, causant des difficultés d'alignement lors de la pose ou de la soudure du siège, avec l'importante accumulation de stress à proximité de la soudure lorsque le bras longitudinal est sujet au chargement de torsion, qui peut être particulièrement dommageable à un carter de point qui est normalement formé d'une mince feuille métallique. L'objectif de l'invention est de fournir une suspension pour véhicule qui évite les problèmes susmentionnés, lequel objectif est atteint grâce à une construction composée d'un essieu et d'au moins un bras longitudinal, où il y a un siège pour chaque bras longitudinal, chaque siège ayant un retrait principal dans lequel l'essieu est placé, le retrait principal ayant un retrait secondaire transversal dans lequel un insert est placé, l'insert étant positivement fixé au retrait principal, et ayant des sections d'extrémité s'étendant passé les bordures du retrait principal, qui sont positivement fixées aux murs adjacents de l'essieu.

In said furniture, the hinge comprises a respective supporting-wall fitting (18) that can be fastened to the supporting wall (14) and a door-leaf fitting (24) that is coupled in a pivoting manner to said supporting-wall fitting via an articulated mechanism (20; 22) and that can be coupled to the inner face of the door leaf or panel.  The door-leaf fitting is preferably configured as a well-shaped part that engages in a recess in the door leaf or panel, lying flush with said recess and comprising laterally projecting fixing flanges that rest against the inner face of the door leaf. The damping device (30) has a damper housing that is located on the door-leaf fitting (24). The cavity of the housing contains a liquid or gaseous damping medium and a resistance element that can be displaced in relation to said damping medium, said element being coupled to an actuating element (39) that protrudes from the housing. The actuating element has a direct or indirect drive connection to the supporting-wall fitting (18), at least during part of the pivoting displacement of the fittings (18; 24) in relation to one another, and transmits the relative displacement of the pivoting fittings to the resistance element. The damper housing (32) is configured as a separate component, which is equipped with laterally projecting fixing flanges (38) that can be fastened onto the fixing flanges of the door-leaf fitting.

Inventor: QUAIL JOHN R
IPC: B29C45/76
Filed: 2005-09-27
Granted: 2010-07-20
Abstract: An intelligent molding system (FIG. 2) is provided that makes use of data directly associated with a molding environment or particular mold (50, 52). Accessible data, typically stored locally in an in-mold memory device (76, 78) or input via an HMI (86), identifies parameters germane to mold set-up and machine operation. Upon receiving such data, a machine controller (80) operates to configure a molding machine (10) to an initial set-up defined by the data considered close to an optimal operating condition for the mold. Mold set-up data can include information relating to a fill profile for a molded article that is partitioned into different zones having different thicknesses and geometries. Weighting factors for the various zones compensate for differing cooling and flow characteristics. The memory (76, 78) can also be used to store historical data pertaining to mold operation, settings and alarms.
