Patent number: 11365474Abstract: A termination unit for a deposition system, comprising a device for effecting a function, the device comprising at least one component comprising electrical steel, and at least one shielding element which is electrically conductive. The shielding element is configured so: an effect of a neighboring current on the component comprising electrical steel, which is not contributing to the function of the device, is mitigated, wherein this neighboring current has a first topology; and so an effect of at least one neighboring current having a different topology than the first topology is not significantly mitigated. The device moreover comprises a current transfer means neighboring the at least one component comprising electrical steel, and adapted for guiding a current according to the first topology and for transferring power to a target when mounted on the termination unit.Type: GrantFiled: October 15, 2018Date of Patent: June 21, 2022Assignee: ANUMECS BVInventor: Dirk Verdyck

Publication number: 20060132529Abstract: A positioning system includes adjustment means for accurately positioning a positioning device relative to a frame. The adjustment means makes a sliding contact with a dedicated lever which makes contact with the frame. The contact surfaces of the dedicated lever are specially shaped in order to obtain a linear behavior of the positioning system. Within a working distance D an equal movement of the adjustment means over a distance ?x is converted into a corresponding movement of the positioning device relative to the frame over a distance ?y. The ratio ?x/?y is substantially constant for movements within the working distance D. When using the positioning system in a printing system, it is possible to measure the position error of printheads having arrays of printing elements only once and adjust the positioning devices carrying the printheads only once to align the printing elements to each other and to the printing direction of the printer.Type: ApplicationFiled: November 21, 2005Publication date: June 22, 2006Inventors: Bart Verhoest, Dirk Verdyck

Patent number: 7023461Abstract: The present invention relates to a method for reducing or eliminating cross-talk when operating a thermal print head for printing one line on a recording medium. Energizable heater elements of a thermal print head are drivable with at least one activation pulse for supplying a controllable amount of heat to the heater elements to generate a graphical output level of pixel areas on thermographic material. According to the method a plurality of subsets of the heater elements are sequentially driven to print pixel areas in each line. The cross-talk between pixel areas printed by heater elements in the same and/or different subsets is reduced by calculating a value relating to heat supplied to an nth heater element in accordance with a predetermined relationship relating the effect of heat from any one heater element after activation thereof on the graphical output of neighboring heater elements in the same and/or a different subset, and by driving the nth heater element in accordance with the calculated value.Type: GrantFiled: December 17, 2003Date of Patent: April 4, 2006Assignee: Agfa-GevaertInventor: Dirk Verdyck
