Abstract: A module for an electrical distribution system is provided. The module includes a socket board electrically coupled to the electrical distribution system. A plurality of sockets is mounted on the socket board. Each socket defines a port. A sensor is positioned within each port and is electrically coupled to the socket board. The sensors are configured to carry at least one of a primary current and a secondary current. A metering component is electrically coupled to the socket board and configured to measure current carried by the sensors. A communication module is electrically coupled to the metering component and in communication with a monitoring device. The communication module is configured to transmit metering data to the monitoring device.

Abstract: A multiprocessor digital amplifier system is disclosed. A first processor is configured to decode a digital signal from a digital signal source. A second processor configured to provide control signals to the first processor. An expansion unit for communicating instructions and data between the processors and a memory device has a first port coupled to the first processor and a second port coupled to the second processor. The expansion unit includes a state generator with circuitry for selecting one of the first and second ports for receiving a memory device access grant. The first and second ports may be granted access in accordance with a selected arbitration protocol. A duration of the memory device access grant selectably constitutes one of a preselected number of accesses and a preselected timeslice. An amplifier amplifies the decoded digital signal from the first processor.
