Abstract: Methods and apparatus for discovering wireless peripheral devices utilizing wireless broadcasts at multiple power levels. A first data packet containing identification information associated with the wireless device is broadcast by that wireless device. The identification information contains at least a location and a functionality of the wireless device. After broadcasting the first data packet, the wireless device broadcasts a second data packet a plurality of times. A first occurrence of the second data packet is broadcast at a first power level and a second occurrence of the second data packet is broadcast at a second power level lower than the first power level. Additional broadcasts at diminishing power levels can further be utilized. Relative proximity of the broadcasting wireless device can be determined based on the lowest power level received from the device.

Abstract: A method is disclosed that generates a first plurality of blocks of pixels corresponding to pixels of a document. A second plurality of blocks of pixels is generated by transforming the first plurality of blocks of pixels, based on values of the pixels of the document to which first plurality of blocks of pixels correspond.
