The following quote was obtained by the news editors from the background information supplied by the inventors: "This invention relates to improvements in a system to connect and multiplex sensor signals. More particularly, the present system uses split core inductive sensors that connect to multiplexable sensor boards to monitor and communicate power loads without requiring the power loads to be de-activated for installation or maintenance of the sensors.
"Electrical distribution panels (e.g. circuit breaker panels) have limited space to install voltage and current sensors necessary for branch circuit monitoring. Running individual wires from each breaker to a central location is complicated and space constrained. Also changing the sensors with different configurations of the breakers is even more complicated. A number of patents and or publications have been made to address these issues. Exemplary examples of patents and or publication that try to address this/these problem(s) are identified and discussed below.

"What is needed is a system to connect and multiplex sensor signals. The system should also be adapted to three phase monitoring and ground fault measurement and monitoring which is not conveniently provided by existing hard wired systems. The system should be adaptable to different types of sensors which existing solutions do not. This disclosure provides the solution that is not being provided by other available or disclosed devices."
In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "It is an object of the system to connect and multiplex sensor signals to install on any panel board configuration where the device gathers precise power information for amps, volts, power factor, watts and kWh--and is certified to provide utility-grade data on each branch circuit metering.
"It is an object of the system to connect and multiplex sensor signals to monitor power metrics from the iBCPM can integrate with any BMS or DCIM system via Modbus TCP, SNMP or BACnetIP. The system is powered by a TrendPoint xD processor for the iBCPM to provide data and event logging as a standard feature.
"It is an object of the system to connect and multiplex sensor signals for the EnerSure iBCPM to be part of an EnerSure platform of products that provides the most accurate, flexible, and adaptable power metering solutions in the market and is used in some of the most prestigious facilities in the world.
"It is another object of the system to connect and multiplex sensor signals for the EnerSure.RTM. iBCPM panel board strip to be linked with EnerSure Bus cards to provide additional monitoring up to 120 circuits on a single iBCPM system. Additional circuits can be added in 4 or 8 circuit groups.
"It is another object of the system to connect and multiplex sensor signals for the EnerSure iBCPM to employ 21 power meter-on-a-chip units on each panelboard strip. Up to 4 panel board strips per units can be connected together to, each EnerSure iBCPM thereby to accommodate up to 84 circuits of utility grade panelboard power data.
"It is still another object of the system to connect and multiplex sensor signals for the system to be adaptable to three phase monitoring and ground fault measurement and monitoring which is not conveniently provided by existing hard wired systems. The system should be adaptable to different types of sensors which existing solutions do not. The number of plug connections may line up with and match the number of circuit breakers on one side of the panel.
"Various objects, features, aspects, and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments of the invention, along with the accompanying drawings in which like numerals represent like components.
