There is provided a content based partitioning system and a method for use in performing content based partitioning of digital media content. Devices and methods according to the invention substantially reduce the pin count of a device because inputting of a multi-bit digital signal preferably does not use more than one input pin. The diffractive component has a diffractive surface and a plurality of strip-shaped diffractive structures located on the diffractive surface. An electrical circuit connects the solar cells for electrical flow and power management, and preferably includes a controller for controlling power from the solar cells, including combining them in series or parallel as optimal for a given systems configuration. A method is provided for receiving information concerning a remotely monitored device, the information being contained in a message that also includes a message type designation.
