Abstract: A pair of electrodes (I, Io) perform both input and keep-alive functions in a plasma charge transfer device (30). The input-keep alive electrodes (I, Io) are formed on opposite walls (16) of the device adjacent an array of transfer electrodes (14) and are capacitively coupled to the ionization gas. Repetitive and selective voltage pulses are multiplexed to the input-keep alive electrodes (I, Io) and synchronized with transfer electrodes pulsing, to provide, respectively, a keep-alive function and the selective input of data to the charge transfer device (30). A pair of erase electrodes (E, Eo) may also be capacitively coupled to the gas. A pulsing technique is described for restoring charge neutrality to the input-keep alive electrodes (I, Io) and erase electrodes (E, Eo) after each input or erase function.

Abstract: A plasma charge transfer device utilizable as a shift register memory and/or display utilizing ionizable gas contained in an enclosure with a plurality of individual transfer electrodes covered with a dielectric material aligned parallel on opposite internal walls of the enclosure, but offset one another, throughout its length. This plasma charge transfer device utilizes: an ionizable gas; an input electrode which can be either directly or capacitively coupled to the gas; capacitively coupling to the gas of oppositely offset transfer electrodes; and the wall voltage which results when charge is transferred as the result of a gaseous discharge occurring between two oppositely offset transfer electrodes -- the additive effect of this wall voltage to an applied voltage such that a gaseous discharge occurs between two transfer electrodes if charge was transferred to one of the electrodes during a previous discharge whereas a gaseous discharge will not occur with this same applied voltage between any two oppositely offset electrodes which do not have the proper charge trapped on the wall of at least one of the electrode pairs. Upon the proper application of command signals, a gaseous discharge can be successively transferred between subsequent oppositely offset transfer electrode pair, one electrode position at a time, or continuously shifted throughout the entire length of the plasma charge transfer device, or may be held stationary at any oppositely offset transfer electrode pair position within the device. When the plasma charge transfer device is used as a shift register memory, information to be retrieved at the register output may be optically or electronically recognized and erased.

Abstract: An electroluminescent display device comprising a plurality of discrete gas cells formed by superimposing a first plate containing a plurality of chambers on a second plate containing a plurality of chambers equal in number to those on the first plate. One side of each cell is capacitively coupled to a common transparent electrode, and the other side of each cell is capacitively coupled to a corresponding segment electrode. The common transparent electrode and the segment electrodes of selected cells are alternately energized, thus resulting in the intermittent ionization, i.e., gas discharge, of the gas within the cell. The illumination provided by the occurrence of the gas discharge in the selected cells is sufficient for the visual display of numeric, symbolic, and alphabetic information.

On ignition wall charges form and only if a voltage of opposite polarity is applied will that voltage produce a further discharge, in the case of non- selected cells the wall charges oppose the ignition voltage and prevent further discharge. A display panel comprises six characters each in the form of a figure of eight made up of seven cells. The cells are connected across X, Y conductors 19, 20 the cells of each character being arranged in one row. The conductors are also connected to transistors 23a...and 33a biased by AND gates 25a...and 36a...operated by the output of a pulse generator 27 and a series input-parallel output buffer 28 connected to a circulating shift register 29. Gates 36a...are connected to the generator via a delay line 37 and to a character counter 38. By actuating selected gates 25, 36 corresponding transistors become conducting and their conductors 19, 20 connected to earth so that a pulse is applied to one side of selected cells by a voltage source 31 via resistors 30, 40. In operation 160 Ásec. pulses are applied to successive gates 36 by counter 38. The generator 27 and delay line 37 supply 8 Á second pulses alternately to gates 25, 36 and the buffer 28 applies signals to selected gates 25 to provide the desired digit. Gates 25a, 36a are turned on for example and transistors 23a, 33a become conducting alternately to ignite only selected cells in each row, e.g. 21a during the 160 Ásec. period. The process is repeated for each row and then sequence repeated so that the six digits are seen due to retention of vision. In a modified circuit the resistors 30, 40 are replaced by diodes.
