A text enhancement method and apparatus for the presentation of text for improved human reading. Accordingly, time and costs spent manufacturing a new resonator can be reduced to thereby lower the unit cost and maintenance costs can be reduced by decreasing the number of assembly processes when changing a bulb. In one embodiment, the inflatable chamber comprises a toroidally-shaped inflatable member defining a central opening adapted to at least partially receive a portion of the structure during inflation of the inflatable chamber. In response to receiving the registration request, the MFP Web application performs at least one of sending to an email address associated with the particular user an email that includes a registration code and a link to the MFP Web application or sending to the MFP the registration code and encoded data including a link to the MFP Web application. For either system, the predetermined threshold may be dynamically varied to determine a value that optimizes performance.
