  • Patent number: 10514399
    Abstract: A system provides indirect current measurement using dynamic sensing of rapidly changing electromagnetic fields. This measurement is achieved using non-contact sensors that are positioned over electric circuit breaker bodies. The system enables the use of readily available, low-cost, mass-produced digital electromagnetic sensors to measure current for circuits in a building. The system may estimate peak electromagnetic field strength from unsynchronized sensor samples. The system may compensate for the low sample rate of the sensors. The system may compensate for smoothing that is performed by sensors so as to be usable as a sensor for a dynamic electromagnetic applications. The system may account for the presence of measurement leakage that causes electromagnetic field distortion. Moreover, the system may infer the electric equipment in use, its time of operation and activity state based on estimates of the alternating electromagnetic field and the use of machine learning or machine intelligence algorithms.

  • Patent number: 10473534
    Abstract: An assessment system and method are described that capture indoor temperature measurements and corresponding outdoor temperature measurements in order to determine a thermal efficiency of a structure. The assessment system identifies quiescent periods and trims these periods to eliminate undesirable influences such as auxiliary heating or solar gain. The quiescent periods are then compared to outdoor temperature differences to determine the thermal efficiency of the structure. The system can model the structure's performance metrics, through inferred qualitative and quantitative characterizations including, but not limited to, the building's rate of temperature change as a function of internal and external temperatures, the building's heating, cooling, and other energy needs as they relate to the building envelope, appliances, and other products used at the site and occupant behavior.
