Publication number: 20190272361Abstract: The invention is a novel system that uses a continuous and competitive authentication process to identify users within an entity's systems. In particular, the invention may continuously collect authentication data across multiple channels (e.g., authentication data obtained through a mobile app, website, telephone, on-site methods, and the like) as well as non-authentication data. The obtained data may be compared with reference data (e.g., historical data) to continuously update a confidence level associated with the user. Based on the confidence level, profile the user to detect any inconsistencies in the data collected over time. The system may further execute one or more competitive processes in parallel with traditional authentication processes to identify potentially unauthorized users.Type: ApplicationFiled: March 1, 2018Publication date: September 5, 2019Inventors: Eren Kursun, Scott Anderson Sims, Dharmender Kumar Satija, David Eugene Swain, Kolt Arthur Bell

Patent number: 6746538Abstract: An apparatus for coating a photoreceptor substrate, such as a photoreceptor belt or a photoreceptor drum, consists of at least one photoreceptor coating fluid reservoir or diptank. The diptank defines an inlet at one end and a conduit with an orifice at the other end. The conduit includes at least one porous element such as a grid, screen or mesh arranged for suspending a plurality of layers of non-contaminating rounded objects, such as stainless steel or glass beads, in the bottom of the conduit. Photoreceptor coating solution supplied to the inlet is thereby forced to flow through the plurality of layers of beads prior to coating a photoreceptor substrate that is inserted through the orifice. As a result, the uniformity of the coating solution is improved as it coats the photoreceptor substrate, thereby reducing coating defects in the finished photoreceptor belt or drum.Type: GrantFiled: November 1, 2002Date of Patent: June 8, 2004Assignee: Xerox Corporation StamfordInventors: Steven J. Grammatica, Eugene A. Swain, Christopher R. Fridd, Kathryn T. Lalone
