Abstract: A vehicle monitoring and notification system (42) includes a route handler (52), a schedule monitor (56), and a communication handler (92). The schedule monitor (56) determines when users should receive notification messages based on data that indicates when vehicles are expected to arrive at certain locations. The route handler (52) communicates with vehicle control units (61) on board vehicles to determine whether and how much any of the vehicles are off schedule. If any of the vehicles are off schedule, the route handler (52) updates the data monitor by the schedule monitor (56) to change when the schedule monitor (56) determines that notification messages should be received by the users. Once the schedule monitor (56) determines that a user should receive a notification message, the schedule monitor (56) transmits a notification request to the communication handler (92). The communication handler (92) then establishes communication with a communication device (99) associated with the user and transmits a notification message to the user.  Therefore, the user is warned of an impending arrival of a vehicle at a particular location.

Title: Collision avoidance in bidirectional database replication
Inventor: STRICKLER GARY E
IPC: G06F17/30
Filed: 2002-03-11
Abstract: A bidirectional database replication system includes a plurality of nodes.  Each transaction at an originating node is paused prior to a commit operation.  Ready to commit tokens are sent to the other nodes in the system to determine if the other nodes are prepared for the commit operation for the paused transaction. If all of the ready to commit tokens properly return to the originating node from the other nodes, thereby indicating that the other nodes are prepared for the commit operation, then the transaction is commited. For lengthy transactions, ready to sync tokens are assigned at one or more predesignated intermediate points in the transaction, and propagate throughout the system in a similar manner. The transaction continues to execute as long as all ready to sync tokens properly return to the originating node. The pause-before-commit and sync point schemes are used to avoid collisions at any of the nodes.

Title: Purification et stabilisation de produits pharmaceutiques a base de peptides et de proteines
Inventor: WOODS RODNEY J
IPC: C07K14/605
Filed: 2000-06-29
Abstract: L'invention concerne des procédés de purification de peptides et de protéines par incorporation du peptide ou de la protéine dans une dicétopipérazine ou dans un agent complexant compétitif pour faciliter l'élimination d'une ou plusieurs impuretés, des composés indésirables, par exemple, du peptide ou de la protéine. Dans un mode de réalisation préféré, un peptide, tel que l'insuline, contenant une ou plusieurs impuretés, des ions de zinc, par exemple, est piégé dans la dicétopipérazine pour former un précipité de peptide/dicétopipérazine/impureté, qui est ensuite lavé avec un solvant destiné à éliminer les impuretés, qui n'est pas un solvant pour la dicétopipérazine et le peptide. Les formulations et les procédés permettent également le transport amélioré des principes actifs à travers des membranes biologiques, résultant par exemple d'une rapide augmentation de la concentration des toxiques sanguins. Les formulations sont constituées de microparticules formées du (i) principe actif, chargé ou neutre, et (ii) un stimulateur du transport qui masque la charge du principe et/ou qui forme des liaisons d'hydrogène avec la membrane biologique cible de manière à faciliter le transport. Dans un mode de réalisation préféré, l'insuline est administrée par voie pulmonaire sous forme de microparticules comprenant de la fumaryl dicétopipérazine et de l'insuline sous sa forme biologique active. La charge sur la molécule d'insuline est masquée par l'hydrogène qui la lie à la dicétopipérazine, permettant ainsi à l'insuline de passer à travers la membrane cible. Ce procédé d'administration de l'insuline résulte de la rapide augmentation de la concentration des toxiques sanguins comparable à l'augmentation résultant de l'administration intraveineuse.

Filed: 1997-11-17
Abstract: Particles incorporating a surfactant and/or a hydrophilic or hydrophobic complex of a positively or negatively charged therapeutic agent and a charged molecule of opposite charge for drug delivery to the pulmonary system, and methods for their synthesis and administration are provided. In a preferred embodiment, the particles are made of a biodegradable material and have a tap density less than 0.4 g/cm3 and a mass mean diameter between 5 µm and 30 µm, which together yield an aerodynamic diameter of the particles of between approximately one and three microns. The particles may be formed of biodegradable materials such as biodegradable polymers. For example, the particles may be formed of poly(lactic acid) or poly(glycolic acid) or copolymers thereof. Alternatively, the particles may be formed solely of a therapeutic or diagnostic agent and a surfactant. Surfactants can be incorporated on the particle surface for example by coating the particle after particle formation, or by incorporating the surfactant in the material forming the particle prior to formation of the particle. Exemplary surfactants include phosphoglycerides such as dipalmitoyl phosphatidylcholine (DPPC). The particles can be effectively aerosolized for administration to the respiratory tract to permit systemic or local delivery of a wide variety of therapeutic agents. Formation of complexes of positively or negatively charged therapeutic agents with molecules of opposite charge can allow control of the release rate of the agents into the bloodstream following administration.
