A system includes participant nodes that unicast a voice stream to a master node and receive a multicast voice stream from the master node. The multicast voice stream may be a mixed voice stream mixing the voice streams of the participants. In this case, each participant performs echo cancellation on the multicast voice stream. Alternatively, the multicast voice stream may be a multiplexed voice stream multiplexing the voice streams of all participants. In this case, each participant de-multiplexes the multicast voice stream and generates a mixed voice stream that does not include that participant. Alternatively, the multicast voice stream received by each participant may be a multiplexed digital voice stream multiplexing multiple mixed streams including one mixed stream that does not include the voice stream of that participant. In this case, each participant de-multiplexes the multicast voice stream to obtain the mixed stream that does not include that participant.

A method for determining lithium battery passivation starts by applying a load across a lithium battery at the start of a test interval. Measurements of the battery's voltage are taken after applying the load, and then again periodically during the test interval. A final measurement of the battery's voltage at the end of the test interval. The state of the battery is then determined based on the first and final measurements, and at least one of the periodic measurements.

In a fire alert system energy is harvested from a wire line pair (408) used to provide primary electrical power from a fire panel central monitoring station to a plurality of remote devices (406). The fire panel central monitoring station begins communications with a remote device by modulating the voltage on the wire line pair so as to communicate a first message (502) to one of the plurality of remote devices. Thereafter, one of the remote devices will respond to the first message with a second message (504) by modulating the voltage on the line pair. Energy is selectively harvested from the wire line pair at one or more of the remote devices in accordance with the remote device address specified in the first message.

FIRE DETECTION SYSTEM WITH DISTRIBUTED FILE SYSTEM
A distributed file system for a vehicle fire system leverages unused memory in slave modules. Such a system comprises file metadata stored on the master module, which includes information about specific files and the location of used and unused memory throughout the system, including memory on the master module and installed slave units. By maintaining the file metadata and sending instructions to slave units to save or read files at certain addresses, the master module can avail itself of unused memory throughout the entire system. This allows the master module to store more information on the system than there is available memory on the master itself.
A system and method for updating the firmware of slave units in a fire system detects whether a new slave unit has been installed and compares the version of the firmware in the newly-installed slave unit with that of previously-installed slave units of the same type (including any backup copies of firmware stored by the master module in a file system). If the newly-installed slave unit's firmware is more recent, any backup copies of the firmware stored by the master module are replaced with an image of the new version of the firmware. Additionally, slave units with older versions of the firmware are updated to the newest version.
A method and system for assigning working addresses to slave units in a vehicle fire system. Slave units responding to a default address are identified along with available working addresses. Individual slave units are isolated at the default address by instructing the slaves to compare their serial numbers to a broadcast serial number until only a single slave responds, wherein bits in the serial numbers are reversed to create a more sparse distribution of the serial numbers of the slave units, and assigning the slave units, which responded to the default address, to the available working addresses.
