  • Patent number: 6121946
    Abstract: A waveform scan system produces two pairs of special waves with special waveforms that are led to front and rear layers of an electrically-conducting media which contains three overlaid layers. In there they form special stationary waveforms which contains a vertical and a horizontal maximum peak lines. These two peak line cross in space and their perpendicular line present a maximum peak point. Under a control unit, this maximum peak point will scan whole screen media and synchronize with incoming signals. The middle layer connect to the signals processor that allows signals to be converted or be reproduced therein. Thereby the time domain serial signals can be reproduced in different locations in the space domain. Vice versa, the space domain signals can be convert or record in a time domain media.

  • Patent number: 5754465
    Abstract: A non-physical movement component recording and reproducing device produces a pair of special waves with special waveforms that form a special stationary waveform. An electrically-conducting media contains three overlaid layers, a first layer contains the special stationary waveform, a middle layer allows signals to be recorded or be reproduced therein, and a third layer allows the signals to be connected. Two diodes are connected in reverse polarity to the third layer wherein one diode is used for recording and reproducing signals, while the other diode is used for erasing unused signals during the recording process. The bias voltage of the diodes is bigger than the peak value of the special waveform, but less than the maximum peak value of the special stationary waveform. The control unit changes at least one of the intermittence length and the phase of the special waves.
