MAGNETIC GRAPHICAL DATA DEVICE |
摘要 |
A coordinate digitizing device is provided with a localized source of magnetic energy positioned with respect to a wire array, each of said wires terminated in a common delay line. The magnetic energy is pulsed at a desired point, initiating a digitization time interval required for a pulse appearing along a wire of the array to traverse the delay line and reach a device for terminating digitization, and is an indication of the relative digital magnitude representative of the magnetic pulse device's position above the array.
