Abstract

A system for remote non-intrusive occupant space monitoring. The system may have sensors and other mechanisms for non-intrusively obtaining information by capturing utility and communication signals, images, light, sound, environmental factors, background information, and so on, about a space and its occupants. The obtained information may be locally or remotely analyzed and modeled by a processor. Models of buildings, behavior, and power systems from the processor may be compared with pre-defined models to infer further information about the space and its occupants. Also, behavioral information may be obtained, inferred and/or learned. The models may be updated with the obtained, inferred and learned information.

one or more certain patterns of the plot correlate with one or more pre-determined patterns representing specific behavior of the element, component, equipment, environment, and/or occupant.

5. The monitor of claim 4, wherein:

if one or more certain patterns of the plot, correlate with the one or more pre-determined patterns representing specific behavior of the element, component, equipment, environment, and/or occupant, then one or more certain patterns of the plot are indicative of the element, component, equipment, environment, and/or occupant, if any, having the certain behavior; and

the certain behavior of equipment, if any, comprise ramping on/off of furnaces, chiller performance, refrigerator usage, stove operation, inverters, motors, lighting activity, and/or other equipment operation at the space.

6. The monitor of claim 2, wherein:
