A gaming machine is arranged with a gaming machine controller and a secondary \u201cqueuing\u201d device, preferably a player tracking controller having a memory. The charge pump circuit can also include a voltage stabilizer circuit connected to the second connection node and configured to regulate the second connection node to have a voltage within a predetermined range about a selectable voltage. Each server may include a scheduler that independently load balances packet flows across servers of the cluster. The media description file may also include a range unit specifying the size of the offsets in the range string. For example, if a business title has too many surprising word combinations or a particular combination is highly unlikely, the business listing is likely to be fraudulent or \u201ckeyword-stuffed\u201d and may be withheld, excluded, removed from search results.
