Disclosed is a digital document management program capable of achieving a third-party certification of document information with reduced amount of meta data. The safety system will generally include a vehicle seat and a sensor. The photosensitive printing element is positioned on a continuous loop of the conveyor and the heatable roller is urged towards the photosensitive printing element on the conveyor. The catalyst array and a portion of each of the MeNWs are removed to provide exposed ends of the MeNWs. The component parts of each of the light units, such as optically effective components that influence the beam path of the light emitted by the lamp, and end cap reflectors are of a standard dimension so that light units of different configurations can use the same elements to reduce the number of different parts required for the group of different light units of the system. This method can be used to form optical or fluidic interconnections to microchannels previously formed on a substrate, or to form both the interconnections and microchannels during the same process steps.
