A tape guide system for supporting magnetic tape about a rotary scan drum of a data transfer apparatus is disclosed. In one embodiment, the thermoelectric device includes a first thermoelement and a second thermoelement electrically coupled to the first thermoelement. The switching circuit couples one of a plurality of antennas to a RF receiver input. The server includes a data structure storing account data for each player, data corresponding to a predetermined secondary game trigger, said trigger data corresponding to at least one of said serial inputs or primary device feature and data representing at least a schedule of winning secondary game outcomes and awards there for. A process modulates the minimum bandwidth setting associated with one or more partitions in response to observed latency relative to the configured threshold. It further has multiple enlarged projecting portions, which are provided at intermediate portions of the wall-shaped projecting portions extending in the flow direction of the cooling fluid and brought into contact with the neighboring battery cells to receive action force therefrom.
