Abstract: A system for monitoring electricity usage comprising a plurality of sender units having sender identification tags wherein the plurality of sender units are capable of being connected to AC power distribution wiring that carries AC waveforms, and wherein the plurality of sender units are capable of being in electrical communication with an appliance having a current draw; and a central detector capable of being connected to the AC power distribution wiring wherein the plurality of sender units are capable of being in electrical communication with the central detector through the AC power distribution wiring, and wherein the plurality of sender units are capable of transmitting a transient pulse on the AC power distribution wiring wherein the transient pulse is embedded at a location on the AC waveform wherein the location is relative to the sender identification tag and wherein the location is further relative to the current draw of the appliance.

Abstract: A facsimile network includes a plurality of nodes (10)-(14) which are disposed at different locations in the world. An originating fax machine (16) is associated with one of the nodes (10) for transmitting a fax over a local public telephone network (PSTN) (18). When the node (10) receives the fax transmission in the normal transmission mode, it then converts it to a digitized compressed and encrypted image which is transmitted over a primary network (24), such as the Internet, to a destination node (14) by a predetermined route. The node (14) then decompresses and de-encrypts the image and converts it to a facsimile image for transmission to a destination fax (20) in a normal mode over a local PSTN (22). A node (12) operates as a central node which can also receive the transmission for routing directly to the fax or for directing via another network link to the node (14).
