Abstract:
A method for transferring information from a host computer system having a storage device for storing data, the host computer system having a connection to a display monitor having a screen, said method comprising the steps of:generating a clocking bit stream of optical pulses at approximately regularly spaced time intervals; converting a source data set residing on the storage device into a data bit stream of optical pulses; forming a predefined area on the screen of the display monitor, said redefined area comprising a plurality of regions; displaying said clocking bit stream of optical pulses by illuminating one of said plurality of regions in accordance with said approximately regularly spaced time intervals; displaying said data bit stream of optical pulses by illuminating another of said plurality of regions different from the one displaying said clocking hit stream so that a bit of said data bit stream is displayed approximately synchronously with illumination of said clocking bit stream; detecting said optical pulses using a sensing device, said sensing device being connected to a portable information device and said sensing device configured so as to detect said clocking bit stream and said data bit stream separately and concurrently; converting said optical pulses of said data bit stream into a target data set in accordance with said clocking bit stream; and storing the target data set within the portable information device.
