  • Patent number: 7051271
    Abstract: Video recordings of meetings and scanned paper documents are natural digital documents that come out of a meeting. These can be placed on the Internet for easy access, with links generated between them by matching scanned documents to a segment of the video referencing the scanned document. Furthermore, annotations made on the paper documents during the meeting can be extracted and used as indexes to the video. An orthonormal transform, such as a Digital Cosine Transform (DCT) is used to compare scanned documents to video frames.

  • Patent number: 7047642
    Abstract: An ink jet recording head and a process for producing the same, and an ink jet recording apparatus are provided that improve the printing performance and also improve the production efficiency. A conjugated body 73 formed by conjugating silicon wafers 50 and 58 is cut, whereby nozzles 22 are opened, and cutting into head chip units is carried out. At this time, deep grooves 84 are formed on the surface of the silicon wafer 58 by anisotropic etching, and they are penetrated by etching on the opposite side. Grooves 90 are formed on the silicon wafer 50 by using the thus penetrated deep grooves 84 as a mask.

  • Patent number: 7050040
    Abstract: An electrophoretic display includes a cell having a viewed region and a non-viewed region. The cell contains a suspending fluid and a first particle species and a second particle species dispersed within the suspending fluid. Application of a first electrical field causes the first particle species and the second particle species to vibrate and separate from: one another, the cell walls, the viewed region, and the non-viewed region. Application of a second electric field, in one direction, causes the first particles to migrate toward the viewed region and the second particles to migrate toward the non-viewed region, effecting a color state. The electrophoretic display may be fabricated from multiple display cells arranged on a substrate.

  • Patent number: 7051199
    Abstract: A system, method and article of manufacture are provided for affording a cryptographic service utilizing a server on a network. Initially, a client is identified utilizing the network. A first key is established, and a tunnel is generated on the network. Thereafter, information is received at the server from the client utilizing the tunnel. Such information is encrypted by the client using the first key. At the server, cryptographic work is performed using the first key.

  • Patent number: 7048901
    Abstract: An electrical connection structure that is able to electrically connect wiring to a biopolymer, a production method of the electrical connection structure, and an electric wiring method which is able to perform wiring on a nanometer-scale. A first aspect of the production method of the present invention uses a carbon nanotube as an electrode, and makes the carbon nanotube contact the biopolymer. A second aspect of the production method applies electric current between the electrode and the biopolymer of the first aspect. The electrical connection structure of the present invention comprises at least the electrode formed by the carbon nanotube and the biopolymer, wherein the electrode is in contact with the biopolymer. In the electric wiring method of the present invention, the electrode formed by the carbon nanotube contacts the biopolymer to complete an electrical connection.

  • Patent number: 7050627
    Abstract: A system and method for generating achromatic components for output incorporate receiving input color data defined in a first color space. The received input color data is converted to intermediate color data defined in an intermediate color space. Typically the intermediate color space is defined only in terms of chromatic components. A black or achromatic component is then calculated. The black or achromatic color component is a function of both the input color data in the first color space and the intermediate color data in the intermediate color space. This black or achromatic color component is associated with the intermediate color data for further processing and output.
