Title: Collision avoidance in database replication systems
Inventor: STRICKLER GARY E
IPC: G06F17/30
Filed: 2003-03-24
Abstract: Database replication systems replicate blocks of transaction steps or operations with synchronous replication, and perform dual writes with queuing and blocking of transactions. Tokens are used to prepare a target database for replication from a source database and to confirm the preparation. Database replication systems switch between a synchronous replication mode and an asynchronous replication mode, and then back to a synchronous replication mode, based on detection of selected events.

Title: Chromatography of metal complexes
Inventor: TRAWICK BOBBY N
IPC: G01N1/00
Filed: 2002-03-04
Abstract: A high performance liquid chromatography method to routinely and reproducibly detect and quantitate metal complexes. The method comprises loading a solution containing metal complexes onto a column, eluting the metal complex from the column with a mobile phase, the mobile phase comprising an excess of a salt of a coordinating anion in a solvent system, and detecting the metal complex with a detector. Eluting the complex from the column with the mobile phase generates a metal complex in which the coordinating anion (which is a competent ligand) out-competes all other potential ligands present for the available coordination sites on the metal. The metal complexes used in the method of the invention can be different metal complexes, or they can be stereoisomers of the same metal complexes. The high performance liquid chromatography method of the present invention is suitable for the separation of diastereomers of the same metal complexes. Also provided is a chiral high performance liquid chromatography method to separate enantiomers of metal complexes. In this chiral high performance liquid chromatography method a chiral column is employed to achieve the separation of the enantiomers of metal complexes.

Title: Data synchronization interface
Inventor: YU JULIE
IPC: G06F17/30
Filed: 2002-08-15
Abstract: Systems and methods consistent with the present invention provide an interface to facilitate the communication between systems. A source system (310) translates data into an XML format and transmits the data to a synchronizer interface tool. The synchronizer tool stores the data in a persistent intermediate storage, such as a queue (325), allowing the source system to go offline or perform other tasks while the data is transmitted to the target system. The synchronizer tool initiates the transmission of the data to the target system. If the target system indicates that it received the data, then the synchronizer tool sends an acknowledgement to the source system indicating the data was received. If the target system does not receive the transmission, the synchronizer tool maintains the data in the present intermediate storage andreinitiates transmission of the data to the target system (300).

Title: Method and system for transferring ip packets by aggregating multiple wireless communication channels for high data rate transfers
Inventor: GHOLMIEH AZIZ
IPC: H04M1/72415
Filed: 2002-10-25
Abstract: A mobile wireless terminal (MWT) (206) receives IP packets (404) destined fo r a ground network (234) in a predetermined sequence order. The MWT (206) fragments each of the IP packets into many smaller packet fragments (406), appends identifying information to each of the packet fragments (408), and transmits the packet fragments in parallel with one another (416) over concurrently operating satellite channels (240a-240n). A receiving station (180) receives the packet fragments (904) transmitted by the MWT (206). The receiving station (180) forwards the received packet fragments to a ground controller (232) over a network connection, based on the identifying information appended to the packet fragments. The ground controller (232) combines the packet fragments (908) into reconstructed IP packets based on t he identifying information appended to the fragments. The ground controller (23 2) also sequences the reconstructed IP packets (1006) in the predetermined sequence order based on the identifying information. The ground controller (232) forwards the reconstructed IP packets (1008) in the correct sequence order to the destination ground network (234). The same sequence of events occur in the opposite direction as well i.e., from the ground controller to the MWT (206).

Title: Wireless communication inside shielded envelope
Inventor: DE LA CHAPELLE MICHAEL
IPC: B64D45/00
Filed: 2004-04-19
Abstract: A system and method limit transmission of wireless electromagnetic device radiation through the windows of a mobile platform outer envelope. The mobile platform includes at least one window on an outer envelope. A shielding layer is applied to the window and electrically grounded to the outer envelope. At least one transceiver hub is located within the mobile platform receiving and/or transmitting the electromagnetic device radiation. An off-board communication device wirelessly communicates with the transceiver hub. The shielding layer attenuates a portion of the radiation contacting the window. Only a communication path between the transceiver hub and the off-board communication device is therefore operable. Wireless device transmission and/or reception via a window path is effectively blocked by the shielding layer, decreasing the potential for disruption to mobile platform electrical systems and interfering with ground-based communication systems.

Abstract: Methods and compositions for flavor enhancement and development in a cultured dairy product employ identification and selection of fat fractions from sources such as milk(butter) fat for use as flavor precursors. The selected fractions are added to the product at a step in the manufacturing process where they are available for flavor development by means characteristic of the product. The selected fractions are preferably enhanced for fatty acids and have low melting points. For a reduced fat product, the flavor precursors are generally added in combination with a fat substitute. Homogenization of all the aqueous protein component in this type of product was an improvement over homogenizing only a portion of this component. The invention is particularly suitable for production of reduced fat cultured dairy products.
