By selectively placing color filters with different transmittance spectrums on an array of modulator elements each having the same reflectance spectrum, a resultant reflectance spectrum for each modulator element and it’s respective color filter is created. The hybrid system has both an internal combustion engine and a motorgenerator. In the preferred embodiment, the consolidated invoicer interface provides at least one access point to each of the invoicers; sets the access point of each of the invoicers for at least one customer; authenticates each of the customers; and automatically requests account information for the customers directly from each of the invoicers. The present invention provides techniques for automatically validating and completing existing ERNs andor constructing new ERNs, based on collected event data.
