Title: A method and system for accessing carrier data
Inventor: HASBANI JACQUES E
IPC: G06F9/44
Filed: 1998-09-25
Granted: 2005-11-22
Abstract: The invention is a method and system of loading a data object representative of carrier data and possible command structures, which can be identified by both name and date fields characteristics, into a Data Access System of a carrier management system. The method begins with receiving a request for an object and then determining whether or not the object resides in a first data table which is indicative of a plurality of characteristics of the object. If the object is not resident in the first data table, then the system assigns an initial time stamp and a permanence value to the object. Additionally, the method and system must determine the memory space, in the Data Access System, required for storing the object. De-referenced objects are removed from the memory until space is available that is greater than or equal to the memory requirement of the object. After memory is allocated to the object, the object is then loaded into the memory for use within the carrier management system. A directory table is then established for the object. The directory table includes: an object name; a set of associated data; and, an object table data pointer. The associated data includes an effective date; an expiration date; and, the modification status of the file.

Abstract: L'invention concerne un appareil automatique muni d'un mandrin à largeur réglable et destiné à positionner les pneus en toute sécurité dans une machine de contrôle des pneus; l'appareil comprend un mandrin inférieur qui se présente comme un ensemble broche et un mandrin supérieur qui se présente comme un ensemble mandrin mobile. L'ensemble broche comprend une broche rotative comportant une partie conique, l'ensemble mandrin comprenant un élément mandrin qui comporte un évidement conique de raccordement. L'ensemble broche et l'ensemble mandrin supportent chacun une demi-jante qui entre en contant avec les talons inférieur et supérieur d'un pneu. Sous l'effet d'un cylindre hydraulique, tout l'ensemble mandrin peut se rapprocher ou s'éloigner de l'ensemble broche; on peut l'arrêter dans n'importe quel point situé entre les positions entièrement levées et entièrement abaissées. En outre, l'élément mandrin peut être déplacé de manière indépendante par des cylindres pneumatiques pour entrer en contact avec l'élément broche, l'ensemble broche pouvant se trouver dans diverses positions par rapport à l'ensemble mandrin. Le mandrin mobile possède une longueur de course accrue pour pouvoir s'adapter aux pneus de dimensions diverses. Les cylindres pneumatiques maintiennent sensiblement constante la force avec laquelle l'élément mandrin entre en contact avec la broche. Une fois le contrôle terminé, un mécanisme de démontage de pneus effectue l'enlèvement forcé du pneu de la jante faisant partie de l'ensemble mandrin.

Title: Optical communication network
Inventor: KOGA MASAFUMI
IPC: H04J14/02
Filed: 1999-12-06
Granted: 2006-08-29
Abstract: A wavelength division multiplexing ring network is constructed using a simple architecture and a fewer number of hardwares between the nodes compared with the conventional ring network. Each node is structured so that any number of multiple waves can be processed, and a fault in the network or within a node is resolved by providing a path-based protection so that switching can be performed without disrupting other nodes or even within one node. The network uses two or four lines of optical fibers, and a half of the fibers are used for communicating in a clockwise direction and a other half of the fibers are used for communicating in a counter-clockwise direction to form a logical network by optical paths contained in optical fibers so as to provide an equal number of relay nodes between two adjacent pairs of nodes throughout the network, where each node includes: multiple optical add/drop circuits; an optical path transmit end and an optical path receive end for freely selecting and outputting multiple combinations of wavelengths to be inserted in each node; and transmission lines provided between the optical add/drop circuits and the optical path transmit end, as well as between the optical add/drop circuits and the optical path receive end for transmitting any multiple waves to be processed within the node so as to establish mutual communication by transmitting processed multiple waves to other nodes. This network design enables to reduce the number of connections between the optical path transmit and receive ends, and also to reduce the number of optical signal op termination circuits.

Title: Warp-tied composite forming fabric
Inventor: SEABROOK RONALD H
IPC: D21F1/00
Filed: 1999-05-25
Granted: 2006-04-04
Abstract: A composite forming fabric comprises in combination a paper side layer having a paper side surface and a machine side layer.      The layers are woven together in a repeating pattern, in at least 6 sheds. All of the paper side layer warp yarns are pairs of intrinsic warp binder yarns, forming an unbroken warp path in the paper side surface, and each in turn interlacing with selected machine side layer weft yarns at points which always coincide with an interlacing point of a regular machine side layer warp yarn with the same weft yarn. After heat setting, the fabrics provide enhanced paper sheet quality, have an increased warp fill exceeding 100%, and have improved resistance to stress and reduced abrasion of the binder yarns in the machine side layer. The reduction in lateral contraction and internal abrasion reduces or delays delamination.

Title: Technique for effectively communicating multiple digital representations of a signal
Inventor: SINHA DEEPEN
IPC: H04B15/00
Filed: 2000-03-13
Granted: 2004-02-10
Abstract: In a communications system implementing, e.g., an in- band on channel AM (IBOC-AM) (also known as "hybrid IBOC- AM") scheme, multiple bit streams are used to represent an audio signal to be transmitted over one or more frequency bands including, e.g., parts of an AM frequency band for radio broadcast. These bit streams contain various and/or equivalent amounts of audio information. In an illustrative embodiment, at least one of the bit streams is a core bit stream containing core audio information. The remaining bit streams are enhancement bit streams containing enhancement audio information. The core bit stream is necessary for recovering the audio signal with minimal acceptable quality. Such quality is enhanced when the core bit stream, together with one or more of the enhancement bit streams, is used to recover the audio signal. In accordance with the invention, the AM frequency band is divided. into subbands. Each of the core and enhancement bit streams is assigned to a respective one of the subbands for transmission. The assignment is conducive to an effective treatment of interference affecting the IBOC-AM system. Other embodiments may include, e.g., communications of the multiple bit streams in accordance with the invention in an IBOC-FM system, a satellite broadcasting system, etc.
