  • Object Oriented Modeling, Simulation and Optimization of Power Electronic Circuits

    Conference Record, June 1996, Vol. 1, pp. 581-585, PESC(IEEE) ’96

    In this paper, a new method of interfacing an optimisation routine with a digital simulator used for simulation of power electronic circuits is presented. This helps the user in arriving at an effective design for a chosen power electronic circuit. The simulation is done using the Advanced Continuous Simulation Language (ACSL). Modeling of power electronic circuit is done using DYMOLA-an object oriented modeling language. In this process, the modeling environment is totally decoupled from the…

    In this paper, a new method of interfacing an optimisation routine with a digital simulator used for simulation of power electronic circuits is presented. This helps the user in arriving at an effective design for a chosen power electronic circuit. The simulation is done using the Advanced Continuous Simulation Language (ACSL). Modeling of power electronic circuit is done using DYMOLA-an object oriented modeling language. In this process, the modeling environment is totally decoupled from the simulation environment, which is state of the art. For a fully controlled rectifier bridge with a two stage filter, the values for filter components are optimised for lower cost against the given design requirements

  • Federated system for monitoring physical assets

    Issued US 7382264

    A system federates heterogeneous monitoring systems to provide end-to-end monitoring information for conveyances with item-layer visibility. A first node of the federated system comprises a first monitoring system and a first port and a second node comprises a second monitoring system and a second port. In parallel with a conveyance being transported between the first node and the second node, the first monitoring system sends an agent to the second monitoring system. The agent comprises logic…

    A system federates heterogeneous monitoring systems to provide end-to-end monitoring information for conveyances with item-layer visibility. A first node of the federated system comprises a first monitoring system and a first port and a second node comprises a second monitoring system and a second port. In parallel with a conveyance being transported between the first node and the second node, the first monitoring system sends an agent to the second monitoring system. The agent comprises logic and/or data necessary to implement processes on the second monitoring agent while the conveyance is at the second port. When the conveyance arrives at the second port, the second monitoring system executes the agent to determine conditions of the conveyance and/or its contents.

  • Two-phase commit synchronizing seal state

    Issued US 7358856

    A conveyance tracking system provides two-phase transaction commit processing for synchronizing seal state information between a seal device attached to a conveyance and a host for tracking conveyances. The system uses a reader device for synchronization and communication between the seal device and host system regarding various operations, such as a lock operation, an unlock operation, and a clear tamper operation. In the first phase of the two-phase commit, the seal device prepares for the…

    A conveyance tracking system provides two-phase transaction commit processing for synchronizing seal state information between a seal device attached to a conveyance and a host for tracking conveyances. The system uses a reader device for synchronization and communication between the seal device and host system regarding various operations, such as a lock operation, an unlock operation, and a clear tamper operation. In the first phase of the two-phase commit, the seal device prepares for the operation and the host executes the operation. In the second phase, the seal device fulfills the irreversible operation, ensuring that the seal state of the seal device and host are in sync.
