Abstract: A power harvesting system employs a saturable core transformer having first and second primary windings and a secondary winding. The first primary winding is a high impedance winding with a large number of turns and the second primary winding is a low impedance winding with a small number of turns. The first and second primary windings are connected to a load. A relay is operable in a first state to connect A/C power to the first primary winding and in a second state to connect A/C power to the second primary winding. When A/C power is connected to the first primary winding, a small current flows in the first primary winding which is insufficient to activate the load but sufficient to transfer power to the secondary winding. When A/C power is connected to the second primary winding, a larger current flows in the second primary winding sufficient to activate the load and to transfer power to the secondary winding.

Abstract: A method of linking a mesh node to a particular physical location is provided which achieves a very high degree of linking accuracy. Linking is authorized to take place only when stringent location verification criteria have been met and utilizes a Linking Application Program in a compatible portable device such as a smartphone. The Linking Application Program takes the installer through a step by step installation and linking process that ensures the maximum possible linking accuracy. The verification criteria requires that the pertinent data be gathered and then utilized to ascertain if indeed a mesh node being installed is in the right location.
