  • Patent number: 10922309
    Abstract: In some variants systems and methods are disclosed that allow a smart contract or other device-executable code sequence to be triggered as an automatic and conditional response to a change of a data element that is used by the code sequence. By using user-identified values as state variables that trigger execution in a blockchain or similar controlled environment, for example, cascading processes can be incrementally and reversibly automated without any necessity for coordination and without compromising security.
    Type: Grant

    Date of Patent: February 16, 2021
    Assignee: DRAGONCHAIN, INC.
    Inventors: Joe Roets, Alex Benedetto, Adam Crowder, Roby Daquilante, Noah Gribbin, Regan Karlewicz, Daniel Luedke, David Rigby, Dean Shelton

  • Patent number: 8460520
    Abstract: Contaminants are removed from raw water or discharge water from plants, such as sewerage and industrial plants, by applying direct current through an array of spaced, alternately charged electrodes to eliminate or minimize clogging of the electrodes with precipitated contaminants. Polarity may be switched periodically to assist in eliminating or minimizing clogging. In illustrated embodiments, electrode arrays are contained in housings of dielectric material to form modules, To increase processing capacity, the modules are arranged in parallel arrays. Alternatively, a single module is scaled up for large or industrial applications or scaled down for personal use. Instead of housing the electrode arrays in modules through which liquid passes, the electrode arrays for some batch applications are dipped in the water or aqueous solutions.

  • Publication number: 20070251828
    Abstract: The invention relates to a method for operating interacting different units, particularly of an installation, with different controllers that control these advanced control sequences, particularly with different control pulses. The inventive method is characterized in that the clock pulses (IPOi) of the different controllers (3.1, 3.2, 3.3) are interpolated to a common system clock pulse (tTiex), and that the control sequences are synchronized. A device suited for carrying out the inventive method correspondingly comprises at least one common interpolation device (5.3) for the controllers (3.1, 3.2., 3.3) for interpolating the clock pulses (IPOi) of the different controllers (3.1, 3.2, 3.3) to a common system clock pulse (tTiex) and at least one synchronization device (5) for synchronizing the control sequences.

  • Patent number: 5749842
    Abstract: There is provided a package for containing a wound dressing, the package comprising a first web and a second web hermetically sealed together around their peripheries, the inside of the package being sterile, wherein the first and second webs include transparent areas which can be superimposed and wherein the internal surface of one of the transparent areas is receptive to marking.
