Some embodiments of the present invention comprise an off-set gear assembly for use in producing cushioning material and methods for using the same. A client generates and sends one or more metering packets to a census service. Upon receiving an input query that includes a word and a part of speech, the retrieval system identifies documents with a sentence that includes that word collocated with a word that is used as that part of speech. A description of the goods has been previously stored in a transaction record that has been previously created within an escrow service. The magnet or magnetic bead selectively couples to a magnetic surface on a screened device and the elongated armature may be adjusted to position the screen of the screened device.
