Abstract: A programmable AC/DC power converter receives a plurality of input voltages and outputs a single voltage from an input voltage system. A transformer receives the single voltage. One of the plurality of input voltages is provided at a center tap of a secondary winding of the transformer. A transformed voltage is output. A rectifier receives the transformed voltage and outputs a DC voltage. A buck regulator receives a DC voltage, creates a regulated voltage, and outputs the regulated voltage and a regulated current to a portable appliance. A error correction system receives a programming signal and regulated signals and verifies that the regulated signal to programming signal ratio is within an acceptable range.

Abstract: The present invention relates to a method and a system for online creation and ordering of customized material for printing, where each customer at front end, through a computerized interface, participates in the process of creating, editing, proof printing and finally ordering print-ready files through Internet, via a printing service provider which automates the production of the print-ready files, and where print shops carefully chosen by the printing service provider automatically receives the print-ready files directly into their printing press. A PDF engine uses two XML files to create a customer PDF document for printing on demand. One XML file, the data XML file, comprises the data and it's typing for printing, and is created by the customer through the computerized interface. The second XML file, design XML file, comprises a description of how said data can be positioned and formatted, in a created document by the customer through said interface.
