Patents by Inventor Hugh Lindsay

Hugh Lindsay has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7453267
    Abstract: A branch circuit monitoring system includes a plurality of current sensor modules that are installable in a panelboard. Each of the current sensor modules may be associated with a respective one of a plurality of branch circuits included in the panelboard. Each of the current sensor modules may include a current sensor, operating logic and a communication module. The current sensor may measure a power parameter of the respective branch circuit associated therewith. The operating logic may be coupled with the current sensor and the communication module, and may direct the overall functionality of the current sensor module. The communication module may be operable to communicate with a device external to the current sensor module.

  • Publication number: 20060066455
    Abstract: Systems and methods for grouping mesh networks. Mesh networks enable energy data to be transferred from an energy sensing device to a destination device using various networks and reduces the need to install metering stations. Embodiments of the invention join or group mesh networks that otherwise are not able to communicate. The connections between the grouped mesh networks can be passive using directional antennas or passive antennas or active using higher power RF devices, solar repeaters, mobile mesh devices, etc. The energy data is routed in a smart manner, by performing load balancing at gateways, by monitoring the signal to noise ratio of available communication paths, etc. Mesh clusters can also be created to define low power clusters, address blocking clusters, and frequency based clusters. Grouping clusters facilitates the efficient transfer of energy data from an energy sensing device to a energy management station.
