Power load control with dynamic capability
First Claim
1. A load control device comprising:
- a utility power line interface configured and arranged for directly connecting to, and providing power from, a power utility line carrying electrical power using alternating current (AC);
an electrical load interface configured and arranged to directly connect to a load generated by a device, including circuitry, at a premises and to provide the electrical power from the power utility line to the load;
a monitor circuit configured and arranged to monitor values for one or more load-responsive parameters of the electrical power from the power utility line;
a wireless communication circuit;
a processing circuit configured and arranged todetect other wireless devices, each including circuitry, using the wireless communication circuit,form, in response to detecting the other wireless devices, an ad hoc network with the other wireless devices,communicate, over the ad hoc network, data regarding an acceptable range of values for each of the one or more load-responsive parameters,detect when one or more of the monitored values fall outside of a corresponding acceptable range of values,adjust the acceptable range of values in response to positional information received from the other wireless devices, andgenerate an interruption signal in response to detecting that the monitored values fall outside of the corresponding acceptable range of values; and
a power control circuit configured and arranged to interrupt the providing of the electrical power from the power utility line to a load in response to the interruption signal.

Abstract
A load control device is directly connected to a power utility line carrying electrical power using alternating current (AC) and to a load provided by a device located at premises. At the load control device, values are monitored for one or more load-responsive parameters of the electrical power over a period of time. A nominal value is determined for each of the one or more load-responsive parameters based upon the monitored values over the period of time. Threshold values are determined for the one or more load-responsive parameters based upon an acceptable deviation from the corresponding nominal value. A load-responsive parameter is detected as being outside of the threshold values. The load control device is then used to interrupt the providing of power to the load in response to the one or more load-responsive parameters being detected as being outside of the threshold values.
