  • Patent number: 6219353
    Abstract: A message hub is provided for use in a message communication system having a plurality of nodes connected to the message hub by a data communication medium for inter-node messaging. The message hub operates in a scheduling phase and a transmission phase. In the scheduling phase, request receiving means receives a messaging request signal is received from each node. In accordance with the messaging request signal, selecting means selects a selected node in the scheduling phase. Granting means generates a grant signal to the selected node for allowing the selected node to transmit a message to the message hub on the data communication medium. The granting means also generates a listen signal to the other nodes for commanding the other nodes to listen to the data communication medium. The message hub enters in the transmission phase in which message receiving means receives a message transmitted from the selected node on the data communication medium.

  • Patent number: 6205158
    Abstract: Architectures for a synchronous transport network of a telecommunications system using transparent transport capabilities are presented. The telecommunications network comprises a pair of transparent multiplexers (TMuxs) connected over a bidirectional high speed span for transparently transporting high rate traffic. Each TMux consolidates traffic from a plurality (I) of linear systems or a plurality of bidirectional self-healing rings, each ring (Ki) having a ring rate Ri and at least two nodes (Ai, Bi). In another configuration, each TMux subtends a plurality of rings, such TMuxes being adapted for connection as ring nodes in a high-speed ring. The upgrades obtained with TMuxes in both the linear and ring configurations provide for per span relief for fiber exhaust where no changes to the existing systems are desired. As well, the bandwidth of an existing system may be increased on a per-span basis or the equipment count may be reduced.

  • Patent number: 6199729
    Abstract: A portable drinking facilitation apparatus is useful for a bicyclist and provides a liquid reservoir and a reservoir delivery tube. The apparatus has a flexible drinking tube having a mounting end and a terminal end. The drinking tube is adapted for shaping, such that said ends are positioned as desired, and the drinking tube will hold the given shape until said ends are repositioned. In its preferred mode, the flexible drinking tube comprises a plurality of tube segments joined end-to-end to form an extended elongate tube. A bite valve is removably mounted at the terminal end of the drinking tube. The apparatus also has a base fitting for receiving the mounting end of the drinking tube. The base fitting is adapted for receiving an end of the reservoir delivery tube and the mounting end of the drinking tube. This arrangement allows water to flow from the reservoir delivery tube, through the base fitting, and into the drinking tube, from which it is dispensed to the user.

  • Patent number: 6106102
    Abstract: A method of printing a desired color image on a printing medium by construction from individual ink drops deposited in pixel arrays includes passing a multiple-nozzle ink-discharging pen across the medium multiple times, each pass creating a portion of a respective segment of the image, and periodically advancing the medium so that the pen creates portions of successively different segments. During each pass, the "portion-creating" function includes discharging from the pen an odd submultiple of the full density of ink desired in the segment of the desired image that is being created, so that printing full density in each segment requires an odd number of passes, preferably three. The medium is advanced by an odd submultiple of the height of the segment being created in each pass and is preferably advanced after each pass of the pen. For the preferred three passes, the odd submultiple of the height of the segment is preferably one-third.
