Abstract: An apparatus 10 for poling piezoelectric material includes a platen 22 which holds a sample 20 of piezoelectric material to be poled and a stage 30 to which the platen is mounted. The stage 30 is arranged to selectively move the platen 22 and thereby the sample 20 which the platen 22 holds. The platen 22 is movable by the stage 30 selectively between a first position and a second position. A corona source 40 generates a corona to which the sample 20 is exposed when the platen 22 is moved to the first position by the stage 30. An electrostatic voltmeter 60 having a probe 62 measures a surface potential of the sample 20 when the platen 22 is moved to the second position by the stage 30.

Abstract: Embodiments of the present invention provide a system for querying a graph based on applying filters to a visual representation of the graph. The system allows complicated graph query operations to be performed with ease visually. During operation, the system obtains data indicating vertices and edges of a graph. The system displays a visual representation of the graph for a user. The system receives, from the user, a command defining a local graph filter comprising a region in the visual representation. The system then filters a representation of the graph, and stores the filtered representation.

Abstract: Printing methods and devices identify distortable ink colors in a print job. These distortable ink colors interact with one another when printed in the same printing pass on the same area of a sheet. These methods and devices control printheads and sheet feeders to separately print the distortable ink colors in different print passes.

Abstract: Embodiments described herein provide a supervisor for fault management at a production system. During operation, the supervisor can obtain a set of sensor readings and a state of the production system. A respective sensor reading is an output of a sensor in the production system. The supervisor can then determine, using an artificial intelligence (AI) model, whether the set of sensor readings accommodates a fault associated with a corresponding sensor. Subsequently, the supervisor can determine an action that mitigates an effect of the fault and modify the set of sensor readings based on the action. Here, the modified set of sensor readings is used by a controller that controls the production system.

Abstract: An image has pixels arranged in perpendicular rows/columns. The size of the image is changed to produce a changed-size image and the changed-size image is output. The process of changing the size of the image adds at least one row/column as at least one inserted row/column. The inserted row/column is made up of data from generating adjacent rows/columns of the perpendicular rows/columns. Embodiments that reduce the size of the image remove the generating adjacent rows/columns that were used to form the inserted row/column and, in such reduction processing the inserted row/column is added where the (now removed) generating adjacent rows/columns were previously positioned. In embodiments that increase the size of the image, instead of removing the generating adjacent rows/columns, the inserted row/column is merely inserted between the adjacent rows/columns.
