Abstract: A touchscreen display having a repositionable virtual input and a method therefor are disclosed. The touchscreen display includes an electronic display displaying a virtual input. The touchscreen display maintains electric communication with a central processing unit (CPU) and a non-transitory computer readable storage medium that stores data corresponding to the touchscreen display. The virtual input is repositionable from a first display position to a second display position based on the virtual input at the first display position satisfying one or more of a number of input attempts, a number of successful input attempts, and a number of failed input attempts satisfying predetermined criteria. When one of the number of input attempts, the number of successful input attempts, and the number of failed input attempts do not satisfy the predetermined criteria, the virtual input can maintain a display position at the first display position.

Abstract: An apparatus for controlling cross curl in corners of sheets between in-line transports includes a curved baffle placed between the two transports. A thin layer of high velocity air is applied to the curved baffle only at lead edge corner regions of the sheets. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert corners of the sheets (Bernoulli effect) towards the curved baffle. By positioning a curved baffle between the two transports and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the corners of the sheets and ensure passage between downstream baffles and acquisition by a downstream transport.

Abstract: A color changing expiration indicator includes a reactive layer and a first barrier layer that covers at least a portion of the reactive layer. The color changing expiration indicator also includes a transmission layer that covers at least a portion of the first barrier layer, and a second barrier layer that covers at least a portion of the transmission layer. The color changing expiration indicator further includes a reactant layer that covers at least a portion of the second barrier layer. The reactant layer changes color responsive to a reaction that occurs between the reactant layer and the reactive layer.

Abstract: A printer includes a printhead assembly and a dryer. A transport mechanism conveys the printed media in a downstream direction between the printhead assembly and a dryer and between the dryer and an output device. The transport mechanism includes an electric field-generating transport member. The transport member includes a continuous belt supported by rollers. The belt is driven to transport the printed media on an upper surface of the belt. The belt includes an electrically-insulating inner layer and an electrically-insulating outer layer. First and second sets of electrical conductors are positioned intermediate the inner and outer layers. Electrical conductors in the second set are grounded and alternate with electrical conductors in the first set, A charging unit selectively applies a voltage to only a subset of the electrical conductors in the first set at a time, to electrostatically attract the printed media to the upper surface of the belt.

Abstract: A universal object holding mechanism for holding three-dimensional objects for printing thereon uses multiple conformable balls mounted within a pattern of holes in a two part back plate. The multiple conformable balls are pressed into an object, which in turn, is pressed against a datum surface that represents desired spacing away from print heads. Vacuum is applied to the multiple conformable balls which grip the object. The multiple conformable balls are filled with particulates that cause the multiple conformable balls to become rigid when the vacuum is applied. This contributes to keeping the object from moving when it is being moved past a print head.

Abstract: A method of forming a three-dimensional printed object having a printed surface image includes ejecting drops of a build material to form the three-dimensional printed object with a plurality of layers of build material and at least one layer of a transparent material. The method operates ejectors to form a printed image with a marking agent so the printed image can be viewed through the at least one transparent layer. A leveler is applied to a surface of the layer of transparent material but not to the printed image.

Abstract: A tandem system of metering and donor rolls is used to apply two different adhesives to a fully adhesive backed multilayer sheet to produce variably distributed adhesives and properties. Each of the two adhesives is unique and is cured differently to create a layer of adhesive that has differing adhesive properties on the sheet. A clear adhesive is applied to a top portion of cards before they are cut from the sheet and has a higher tackiness than the adhesive applied to the rest of the cards on the sheet in order to reduce glue buildup on blades cutting the cards from the sheet.

Abstract: A method of manufacturing a three-dimensional object facilitates the removal of support material from the object. The method includes forming at least a portion of a support for the object with support material containing nanoparticles of a material that readily converts microwave energy into heat. The object and support are moved to a position opposite a microwave radiator and the microwave radiator is operated to begin a change of the phase of the portion of the support material containing the nanoparticles before beginning a change of the phase of a portion of the support made from the support material alone. A controller either monitors the expiration of a predetermined time period or a temperature of the object to determine when the microwave radiator operation is terminated.

Abstract: An object surface treatment system facilitates the treatment of articles of manufacture before they are printed. The system includes a chamber having walls and a lid configured to close the chamber, a flexible member mounted to the lid of the chamber, a vacuum source operatively connected to an interior volume of the chamber, and a plurality of actuators. A controller is configured to operate the actuators and vacuum source to move the applicator to apply a chemical to the flexible member, move the lid to close the chamber, produce a vacuum within the chamber and move a portion of the surface of the flexible member into engagement with a surface of an object within the chamber, cease operation of the vacuum source to enable the flexible member to return to a position adjacent the lid, and remove the lid from the chamber for removal of the object from the chamber.

Abstract: A universal gripper includes a set of pivoting fingers on pins mounted uniformly around a fixed ring. The fingers attached by springs to a movable ring are able to rotate inward, toward the center, until they meet an object and stop. Multiple universal grippers could be stacked to allow for different contours throughout objects and facilitate the pivoting fingers conforming and wrapping around a centerline of the objects. Once the universal gripper fingers are in contact with the surface of the object, they stop moving and springs attached to the fingers elongate as the movable ring continues to move over its full range of motion. An alignment tool can be used for staging and acquiring objects in a repeatable and consistent manner.
