    Abstract: A power management integrated circuit for monitoring at least one parameter of a power system is disclosed. The integrated circuit comprises first logic operative to receive digital signals and produce at least one power parameter. The first logic comprises at least one processor core. The integrated circuit further comprises at least one random access memory coupled with the first logic. The at least one random access memory is operative to store the at least one power parameter. The integrated circuit further comprises second logic coupled with the first logic and operative to process at least one incoming communication packet and generate at least one outgoing communication packet encapsulating the at least one power parameter. The integrated circuit further comprises a communications interface operative to receive the at least one incoming communication packet from outside the power management integrated circuit and transmit the at least one outgoing communication packet out of the power management integrated circuit. Power monitoring devices incorporating the integrated circuit are also disclosed.

    Abstract: Systems and methods for ensuring data integrity in a mesh network. A mesh network can include multiple RF devices. Transmitting quality data in or on the mesh network is improved using communication validation functions. The communication validation functions ensure a reliable communication network, preserve data during a network outage, and validate data. The communication validation functions can measure or control data quality within a communication and analysis network. The communication validation function operates to control data quality, for example, by measuring the quality of wireless links, ensuring the presence of redundant links, testing the ability of the mesh network to establish a backup communication path, generating alarms based on communication thresholds, tracking the communication path followed by communication packets, and identifying placement locations for additional RF devices.

    Abstract: Power quality detection, monitoring, reporting, recording and communication in a revenue accuracy electrical power meter is disclosed. Transient events are detected by monitoring the wave shape of the electrical power and comparing deviations to a known threshold. Sags and Swells are detected by computing root mean square value over a rolling window and comparing the computed value with a known threshold. Harmonic frequencies and symmetrical components are quantified by a known algorithm and compared with a known threshold. Incoming waveforms are stored to memory. All recorded and computed data is moved to non-volatile storage via direct memory access transfer in the event that a power quality event jeopardizes the operating power of t he meter. Further, the meter provides a power supply utilizing high and low capacitive storage banks to supply sufficient energy to survive short durati on power quality events which jeopardize the meter's operating power.
