  • Patent number: 6993397
    Abstract: A method for developing and using real time applications for a dynamic system having a sensing subsystem, actuation subsystem, a control subsystem, and an application subsystem utilizes stochastic compute time algorithms. After optimization functions, desired state and constraints are received and detector data has been provided from a sensor subsystem, a statistical optimization error description is generated. From this statistical optimization error description a strategy is developed, including the optimization errors, within the control subsystem. An execution module within the control subsystem then sends an execution strategy to various actuators within the actuation subsystem.

  • Patent number: 6990126
    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.

  • Patent number: 6989516
    Abstract: A ferromagnetic layer is bonded to, or coated on, or in other manner applied to, the surface of a heatable fuser member for fusing dry toner in an image forming device. The ferromagnetic layer promotes inductive heating of the heatable fuser member based on high hysteresis loss exhibited when the ferromagnetic layer is exposed to a magnetic field created by the current flowing through an induction coil or other like device. Suitable materials for the ferromagnetic layer are those which exhibit a high coupling efficiency to the imposed magnetic field. A result is substantially controllable, consistent heating of the heatable fuser member to fuse dry toner onto or into the image bearing surface of an image receiving medium.

    Abstract: A system, method, and article of manufacture are provided for pricing a cryptographic service on a network utilizing one or more cryptoservers. A request for a cryptographic service is received from a user utilizing a network. The request is received by a cryptographic service provider. A contract is generated based on a variable pricing scheme in response to the request. The contract is sent from the cryptographic service provider to the user utilizing the network. A method is also provided for auditing a security provision on a network utilizing a cryptoserver. A cryptographic key is obtained such as by obtaining it from a trusted source or generating the key. A plurality of users are allowed to request that a cryptoserver use the cryptographic key to sign a message in violation of a security provision. It is determined whether the cryptoserver signed the message in response to the request.

  • Patent number: 6989839
    Abstract: What is disclosed is an image processing method for enabling one to print color graphics and other recognizable objects on monochrome printers while retaining color differences. More specifically, the present method is for preserving color discriminability in a grayscale representation. The method involves first sorting colors according to at least one characteristic dimension of a color space such as lightnesses. The color space preferably is a luminance-chrominance color space, although others are envisioned. The sorted colors are adjusted by a metric appropriate to the color space such that the metric imparts a degree of distinction among the colors along the chosen characteristic dimension. The spacing between two adjacent sorted colors can be constant, or weighted by the total color difference between the two colors in the original color space. Color difference can be calculated using for example ?E*ab, ?E*LCh, ?E*94, or DE2000 metrics.
