Aspects of the present invention are related to systems, methods and apparatus for monitoring and controlling energy usage. In operation, a background image is generated, wherein the background image comprises coded glyphtone cells based on grayscale image data values, each of the halftone cells comprising one of at least two distinguishable patterns. A process for fabricating the package includes a partial etch that defines the bottom surface of the embedded die pad and may include a through-etch that leaves one or more of the contacts or leads integrally connected to the embedded die pad.
