  • Patent number: 10748597
    Abstract: A computer-implemented method for writing to and reading from a printed memory device is provided. Data to be written to the printed memory device is segmented into a plurality of data portions. Each data portion of the plurality of data portions is written to a memory cell of the printed memory as a tuple using a determined encoding scheme that is characterized by a voltage and a pulse width. The voltage that is used for the encoding scheme is within a predetermined polarization regime of the printed memory device. Tuples of data can be read from memory cells of the printed memory using a decoding scheme.

  • Patent number: 8169210
    Abstract: In the illustrated embodiment of the invention a scanning system is provided for scanning a chargeable surface for latent image detection. The chargeable surface is charged to a first potential, and a scanner probe is charged to a second potential within a predetermined potential difference from the first potential. The scanner probe is oscillated at a selected frequency and reads or measures the oscillation current that is induced from the oscillation and detects any latent images or other electrostatic distributions on the chargeable surface. A processor processes the probe measurements for determining the potential of a latent image on the chargeable surface based on the scanner probe readings.
