  • Patent number: 8933864
    Abstract: A flat panel display including a plurality of electrically addressable pixels; using a passive matrix on a first substrate, a passivating layer on at least partially around the pixels; a conductive frame on the passivating layer, and a plurality of cold cathode emitters on select portions of the conductive frame within the display, wherein exciting the conductive frame and addressing one of the pixels using the associated passive matrix causes electrons to strike at least one of the pixels and result in the emission of light from those pixels. Using a metal layer (ML) on a second substrate the extent of electrons emitted is enhanced through the incorporation of a noble gas or mixture thereof, causing a multiplication of the electrons emitted by the cold cathode when the gas is ionized.

  • Patent number: 8228352
    Abstract: A flat panel display comprises: a cathode; an anode having a plurality of associated pixels; and, a control frame. The display has nanotubes disposed thereon; such that when a predetermined voltage is applied to the frame the nanotubes emit electrons that strike the pixels thus increasing the brightness of a displayed image. The display also includes a plurality of TFT circuits, each being associated with a corresponding one of the pixels. Increasing the predetermined voltage, after the threshold has been reached, will increase the quantity of electrons emitted by the nanotubes and increase the brightness of the image displayed. This voltage applied to the frame and associated nanotubes may be a pulsed voltage.

  • Patent number: 8200974
    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.

  • Patent number: 8120550
    Abstract: The present invention relates to a display device that employs edge emitters as a source for pixel electrons. The edge emitters allow the viewing glass plate to be made very small or eliminated, thereby substantially reducing the size of or eliminating the spacers typically utilized in conventional display devices and thereby enabling a simple and compact assembly structure. In one embodiment a pixel configuration comprises a phosphor area disposed between a plurality edge emitters, each of which are associated with tynes that are adapted to reduce the distance between the emitters and that separate the phosphor area into segments such that the emitters emit electrons when the voltage between a phosphor segment and the an emitter exceed a threshold voltage to cause the phosphor segment to emit light.
