Google's Energy Disaggregation patent

[Jack Kelly]

There was some talk in late 2014 that Google had released a patent on energy disaggregation.  I can't find it though.  Does anyone have a link to Google's energy disaggregation patent?

I don't think that this will answer your question but here is what I've found:

• Google's powermeter abandonned project (that used to claim it would revolutionize energy disaggregation) 
• Google Inc. Patent  #20140371922 Systems, methods and apparatus for encouraging energy conscious behavior based on aggregated third party energy consumption
• Google Inc. Patent #20140371937 Systems, methods and apparatus for monitoring and managing device-level energy consumption in a smart-home environment

I hope it'll help

very interesting, thank you!  I think the last item you mentioned is the closest to a 'NILM' system.  Thanks again.

I don't see a patent actually relating to disaggregation.

Honeywell has this one: http://www.google.com/patents/EP2570775A1?cl=en
It has a workflow for training a signature into a database that is used in a disaggregation algorithm. The actual algorithm does not appear to be part of the patent.
