20090102389 | Matrix phosphor cold cathode display employing secondary emission - A vacuum flat panel display including: a plurality of electrically addressable pixels; a plurality of thin-film transistor driver circuits each being electrically coupled to an associated at least one of the pixels, respectively; a passivating layer on the thin-film transistor driver circuits and at least partially around the pixels; a conductive frame on the passivating layer, said frame and pixel area coated with an insulator; and, a plurality of cathode emitters are deposited on the coated frame while phosphor is deposited on the coated pixel; wherein, exciting the cathode emitters and addressing one of the pixels using the associated driver circuit causes the emitted electrons to induce one of the pixels to emit light. By introducing a noble gas or mixture, and a ML layer having a DC, AC or pulsed voltage applied thereto, one creates a plasma to form a sheath boundary at the insulator causing electron multiplication and increased illumination. | 04-23-2009 |
20090115756 | Matrix phosphor cold cathode display employing ion activated phosphors - A vacuum flat panel display has a plurality of associated pixels each having a phosphor and nanotubes and a surrounding control frame. When a pixel voltage is negative relative to the frame then a plurality of electrons emitted by the nanotubes are attracted to the frame whereby electrons strike gas atoms in transit to the frame and produce ions and additional electrons; wherein said ions returning to the pixel result in phosphor illumination. The invention is also a process for illuminating a phosphor in a flat panel display comprising: a plurality of associated pixels each having a phosphor and nanotubes; applying a pixel voltage negative relative to a frame; attracting to the frame a plurality of electrons emitted by the nanotubes; whereby electrons strike atoms of a gas in transit to the frame producing ions resulting in phosphor illumination. | 05-07-2009 |

20100174908 | METHOD AND SYSTEM FOR SECURELY EXCHANGING ENCRYPTION KEY DETERMINATION INFORMATION - A system and method for securely exchanging plurality of information items used to generate a plurality of encryption keys used in a public key-and-private key system. In accordance with the principles of the invention, elements of exchanged information items, such as public key and synchronizing indictors are encrypted before the exchange. The information item element is encrypted using an encryption key determined from information items that were previously exchanged. The encryption of information items used to determine subsequent encryption keys provides additional security to the encryption key used in the transmission of informational data as the encrypted elements of the information item must be decrypted before the data message encryption key can be decrypted. The process of exchanging encrypted information items can be repeated until an agreed upon number of encrypting keys is determined. | 07-08-2010 |
