Abstract: Power line installation wires which carry electricity to energize devices connected to the wires can also be used simultaneously to carry other electrical signals that convey information or control between devices connected to the wires. With regard to the disclosed power line communication system and method and related components and processes, each device to be connected to an electric power line installation can be uniquely identified (referred to as the device's electronic genetics) in such a manner that practical applications are not limited as to the number of devices connected to, or as to complexity of information or control effected by communications over, the wires of the power line installation. With its unique identity, any such device can be connected to any power line installation to communicate with any other such device connected to that installation so long as the identity information and linked operational files are within the system of devices connected to the particular installation.

Abstract: The disposable liquid beverage container of the present invention comprises a first compartment for sealably containing a beverage and a second compartment adjacent the first compartment. A barrier having a translucent portion separates the first and second compartments. A light source and an energy source electrically connected to the light source are disposed in the second compartment. A switch activates the light source such that the light source shines through the translucent portion of the barrier and illuminates the beverage disposed in the first compartment of the container. A holographic image embedded in a film attached to an outside of the container is created within the first compartment when the light source is illuminated. Methods are also provided.
