Patents by Inventor Vlad Skorokhod

Vlad Skorokhod has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9441131
    Abstract: Exemplary embodiments provide nanotube-containing coating compositions and methods for making and using the coating compositions. In an exemplary embodiment, the coating composition can include a plurality of nanotubes (e.g., carbon nanotubes (CNTs)) dispersed stably and uniformly in a polymer matrix containing fluoropolymers. The coating composition can further include stabilizers to allow a stable and/or uniform dispersion of the plurality of nanotubes in the fluoropolymers. The nanotube coating composition can be coated on an article surface to improve mechanical robustness, and electrical and thermal conductivity of the coated article. The coated article can be used as, for example, a fuser member, a fixing member, a pressure roller, or a release agent donor member in an electrostatographic printing machine or process.

  • Patent number: 8913917
    Abstract: A vibration-assisted bias charge roll cleaning system includes a bias charge roll cleaning member connected to an actuator for causing the cleaning member to vibrate. The actuator is controlled to vibrate according to a predetermined pattern, and at desired frequencies at particular modes. The cleaning member is configured to be movable to a contact-cleaning position and a cleaning member cleaning position at which the cleaning member is separate from the charge roll.

  • Patent number: 8850908
    Abstract: A method and structure for a device including a non-contact gap control device for maintaining a distance between surfaces can include a pliable platform, a frame to which the pliable platform is secured, an aerodynamic floating (AF) head attached to the pliable platform and a probe for measuring, testing, and/or characterizing a substrate adjacent to the AF head. A pressurized gas source can be coupled to the AF head, such that a pressurized gas is ejected onto the substrate to maintain a distance between the substrate and the AF head during measurement. While the frame can be held immobile, the pliable platform can react in response to irregularities in the substrate to maintain a generally constant distance between the AF head and the substrate.

  • Patent number: 8849160
    Abstract: A bias charge roller includes an electrically conductive core. An outer layer is axially supported on the core. The outer layer is either conductive or semi-conductive. The bias charge roller further includes a continuous raised pattern on the outer surface of the outer layer. The continuous raised pattern is configured to contact a charge-retentive surface of an electrophotographic imaging member so as to charge the charge-retentive surface. The bias charge roller can be employed in an image forming apparatus.
