  • System and methodology for authenticating trading cards and other printed collectibles
    Publication number: 20040101158
    Abstract: A proposed system and method for validation and confirmation of the authenticity of trading cards or other printed collectibles. By providing suitable embedded code as authentication information printed on the trading card at time of manufacture or by exploiting inherent characteristics, the card owner or dealer may readily ascertain the match of a given card with stored data and thereby know if that card is genuine and thus the true value of the trading card.

  • Optical pulse timing detection apparatus, optical pulse timing detection method, optical pulse timing adjustment apparatus, and optical pulse timing adjustment method
    Publication number: 20040101301
    Abstract: Incident signal beam pulses are transmitted by an on-state region, and an optical path for the signal beam pulses is spatially switched in an optical switch. Signal beam pulses transmitted by the on-state region of the optical switch are detected at a pixel corresponding to a transmitting region of a photo-detector equipped with a plurality of pixels. A timing computation unit acquires position information of a pixel at which a predetermined signal beam pulse has been detected, on the basis of a result of the detection conducted by the photo-detector, and computes timing of arrival of a predetermined signal beam pulse at the optical switch on the basis of the position information of the pixel and time when a region corresponding to the pixel is brought to an on-state.

  • Systems and methods for producing superradiance using molecular magnets
    Publication number: 20040100997
    Abstract: Superradiance is generated by generating coherent radiation in the 10 gigahertz (1010) to terahertz (1012) regions of the electromagnetic spectrum. The radiation is produced by pulsing a micro crystal of a molecular magnet in a cavity or between a pair of superconductor mirrors at Kelvin or milli-Kelvin temperatures. The coherence and source of the radiation result from enhanced quantum mechanical spin tunneling. Alternatively, the radiation may be obtained by moving the crystal in and out of the field of a permanent magnet.

  • Method and system for securely Sharing files
    Publication number: 20040103280
    Abstract: A system and method for sharing files securely includes server software on a first device configured to communicate with server software operating on one or more other preauthorized devices, such as a second device. The servers communicate with each other securely using cryptographic information exchanged during a preauthorization phase using a range-limited communication channel. The server on the first device obtains file information from the other preauthorized device(s) and combines the information with local file information from the first device. This combined file information is sent to client software operating on the machine, which presents the combined file information to users.

  • DISTRIBUTED HIGH EFFICIENCY RF SUPPLY
    Publication number: 20040100534
    Abstract: An acoustic inkjet print head having the RF generator and amplifier located at the load location for directly driving the load is disclosed. In so doing the power distribution medium, e.g. transmission line and any power divider device are eliminated. The overall power efficiency can be near to the high efficiency amplifier. In the case of Class-E, greater than 90 percent efficiency can be achieved. Due to the miniaturization of components the high efficiency power supply can be shielded effectively to minimize EME and can be further be integrated to a MCM or IC.

  • Printing to a client site from an application running on a remote server
    Publication number: 20040100651
    Abstract: A method for printing at a local printer using the resources of a networked remote application server in which the networked remote application server responds to a print executable request from a local client by downloading a print proxy executable that obtains printing parameters. Upon receipt of printing parameters from the print proxy executable, the networked remote application server generates a printer-dependent data stream and downloads the data stream to the print proxy executable running on the local client. The print proxy executable then uses local printer utilities to execute the print job.

  • Method for monitoring and encouraging community activity in a networked environment
    Patent number: 6742032
    Abstract: The method of the invention overcomes the problems in a community when the amount of interaction drops off through the use of “community crickets.” A community cricket monitors the amount of community activity, establishes criteria for deciding when a community is sleeping and uses that criteria for initiating a recovery mechanism for “re-awakening” the community. A community is “sleeping” if the level of activity falls below some predetermined level or criteria. By monitoring the community's activity, the community cricket can prevent sleeping communities from dying. Various methods to detect and to re-awaken sleeping communities are defined.

  • Flexible imaging member seam treatment
    Patent number: 6740182
    Abstract: A flexible imaging member seam treatment method comprising bonding a thermoplastic polymer film to the seam of the flexible imaging member after placing the film on the seam. The film is bonded by heating the film above a glass transition temperature of at least one of a thermoplastic polymer from which the film is made and a polymer from which an imaging layer of the flexible imaging member is made. The film can be formed on a flexible, removable substrate. Treatment according to embodiments significantly improves seam region physical properties, greatly reducing cracking and delamination resulting from bending stresses induced by traversal of rollers.

  • System and method for automatically tensioning wires and for retaining tensioned wires under tension
    Patent number: 6740878
    Abstract: A wire tensioning apparatus and method tensions one or more wires by moving the tensioning function from a wire module to an apparatus external to the wire module. Within the wire module, the wire is placed between a movable member and a stationary member. Tension is placed on the wire and adjusted until the desired tension and/or vibrational frequency is met. Once the desired tension and/or vibrational frequency is met, the wire is clamped between the movable and stationary members within the wire module in order to maintain the achieved tension and/or vibrational frequency.

  • Method and apparatus for formatting OCR text
    Patent number: 6741745
    Abstract: Following scanning of a document image, and optical character recognition (OCR) processing, the outputted OCR text is processed to determine a text format (typeface and font size) to match the OCR text to the originally scanned image. The text format is identified by matching word sizes rather than individual character sizes. In particular, for each word and for each of a plurality of candidate typefaces, a scaling factor is calculated to match a typeface rendering of the word to the width of the word in the originally scanned image. After all of the scaling factors have been calculated, a cluster analysis is performed to identify close clusters of scaling factors for a typeface, indicative of a good typeface fit at a constant scaling factor (font size).
