Abstract: A pump panel training device is provided and includes a plurality of simulated gages operable to imitate gages upon a fire truck pump panel, a plurality of simulated controls operable to imitate controls upon the fire truck pump panel, and a simulated water hose operable to imitate one of water temperature changes, water temperature pressure, and water hose vibration for the fire truck pump panel.

Abstract: Computationally efficient DTMF detection methods and apparatus are presented that meet all of the ITU recommendations using the modified non-uniform DFT. The system of the present invention employs a high band filter block and two low band filter blocks to detect power at the 8 DTMF tones. The frame length of the high band filter blocks is one half the length of the low band filter blocks. The frame lengths are chosen to meet the ITU frequency selectivity requirements for all DTMF frequencies. The frames of the two low band filter blocks are staggered to produce outputs alternately, and are aligned with respect to the frame of the high band filter block to produce low band filter block outputs that coincided with the high band filter block outputs without the need for signal buffering. A system of power level tests are employed in conjunction with a system of timing tests to ensure that all ITU timing and frequency constraints are met.

Abstract: Methods for obtaining Internet-type advertisements, modifying those advertisements to fit designated advertising spaces allotted by a plurality of different and unrelated online newspaper websites, and automatically placing those advertisements. Preferred embodiments permit online advertisements to be tracked, audited and/or modified, at any time during an advertising campaign.
