Publication number: 20220404381Abstract: An improved system and method for the selection and dispensing of reagents onto a target testing medium in an automated laboratory environment. The system utilizes multiple carousels rotatably-mounted upon a central turntable. The position of the central turntable, as well as the rotation of each carousel is controlled by a microprocessor-based control system. Multiple dispensers, each capable of storing and dispensing a particular reagent, are mounted about the circumference of each carousel. This configuration provides much higher reagent density than previously available. The testing medium is positioned at one or more loading stations. The control system directs the central turntable to a position from which a selected one of the carousels can be rotated so as to position a selected dispenser above the testing medium.

Patent number: 10166790Abstract: A printing device includes a print media pathway connecting a print media source with a marking component. A flexible member, positioned in the pathway, is deflected by a moving sheet of media to be printed by the marking component. A sensor system outputs a signal in response to a detected deflection of the flexible member. A weight output component outputs a weight-related value for the sheet based on the output signal. The weight-related value may correspond to one of a predefined set of print media weight ranges, each range associated with one or more respective settings for the printing device. An adjustment component adjusts the settings of the printing device based on the weight-related value. This allows the printing device to respond dynamically to changes in print media weight without the need to be provided with the weight of the print media currently installed in the printer by a user.Type: GrantFiled: August 8, 2017Date of Patent: January 1, 2019Assignee: XEROX CORPORATIONInventors: Michael John Wilsher, Simon Neil Jowett, Paul Simon Golding, Stephen Canning

Patent number: 10047235Abstract: What is disclosed is a method for encoding liquid ink with a biomarker which can be traced back to a specific inkjet printer. In one embodiment, an aqueous solution containing a biomarker is combined with a volume of liquid ink. The biomarker comprises a nucleic acid. An ordering of nucleobases forming that nucleic acid has a code sequence. In one embodiment hereof, the nucleic acid is constructed using a code sequence which contains, at least in part, the device specific serial number of the inkjet printer. The encoded liquid ink is added to an inkjet printer and the code sequence encoded in that ink is associated with that particular inkjet printer. The inkjet printer is then used to deposit the encoded ink onto a media substrate. In other embodiments, a fluorescent marker is also added with the volume of liquid ink such that the ink fluoresces under an ultraviolet light.Type: GrantFiled: December 8, 2015Date of Patent: August 14, 2018Assignee: Xerox CorporationInventors: Michael John Wilsher, Jeremy Brook Lewis
