  • Patent number: 7883389
    Abstract: A method and apparatus is disclosed for rapidly joining a first glass substrate to a second glass substrate. The first glass substrate and second glass substrates are separated by a peripheral glass spacer or frame. The glass frame is sandwiched between the first and second substrates. A layer of glass frit is placed on the top and bottom surfaces of the frame or about the top and bottom peripheral edges of the substrates in contact with the frame. Heat is then applied substantially solely to the periphery of the substrates about the frame to cause the frit to melt thereby securing the top substrate to the bottom substrate.

  • Patent number: 7792285
    Abstract: 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.

  • Publication number: 20090115756
    Abstract: 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.
