Embodiments of a system and a method for detecting voids in a cementitious board can be used in connection with the manufacture of products, including cementitious board products such as gypsum wallboard, for example. Such systems and methods can be used to generate numerical void measurements based upon a series of thermal images obtained during the continuous manufacture of the cementitious board.

The present disclosure relates to generation of forming instructions to form one or more three-dimensional (3D) objects and/or analyzing any failure. The failure may comprise a failure of one or more apparatuses utilized during the forming process (or any components of the apparatuses). The failure may comprise a failure in at least a portion of the 3D object during and/or after its formation. The failure may be analyzed before, during, and/or after generation of the forming instructions.

Embodiments of a system and a method for determining an edge hardness value for a cementitious board can be used to effectively determine the hardness of the board after it has been made and dried at a predetermined location, such as, at a stacking station, for example. An actuator assembly can manipulate a punch such that the punch is inserted into one of the edges of one of the cementitious boards in the stacker in a controlled manner. A force gauge can be associated with the punch to measure the resistance force exerted by the cementitious board in response to the punch being inserted into its edge. The measured resistance force can be used to determine the edge hardness value.

The present disclosure relates generally to methods of analysing and manufacturing gypsum panels, for example, suitable for use as building surface products. The present disclosure relates more particularly to a method of forming a gypsum panel. The method includes forming a porous slurry layer on a receiving surface using a plurality of operating parameters, and allowing the porous slurry layer to set to form a gypsum core of a gypsum panel. The panel is then cut to form a cut surface that extends through the gypsum core, and an image of a region of the cut surface is captured. The image is analysed to identify bubbles intersecting the cut surface. A measure of bubble contact in the gypsum core is then calculated from the identified bubbles in the image. Based on the measure of bubble contact, an operating parameter used for forming the porous slurry layer is modified.

This invention provides systems and method for monitoring three-dimensional printing of printing material. A system comprises two coplanar and electrically conductive electrodes and a substrate, which provides a printing surface. The proximate edges of the electrodes, which are on the surface, are separate by a distance ranging from 5 mm to 300 mm. Each electrode is smaller in area than the substrate. The system also comprises a plurality of layers, which are formed layer-by-layer by the printing, and are derived from the printing material. The electrodes are electrically oppositely charged, as enabled by an alternating electric current between the two electrodes. The current partly flows in the layers. The two electrodes exhibit between them a capacitance ranging from 0.1 pF to 10 nF.

There is described an online inspection method and system having an illumination system that provides bright-field and dark-field illumination concurrently or sequentially, at varying intensities, in order to acquire images that may be read by an image processing device. The image processing device may obtain measurements of features in the images and evaluate acceptability of the features.

Machine and method for compacting ceramic powder (CP); a layer of non-compacted ceramic powder (CP) is conveyed in a feed direction (A) through a compacting device (2); downstream of the compacting device (2) there is positioned a detection device (8) which detects the density of the layer of compacted ceramic powder (KP); the quantity of ceramic powder (CP) fed to the compacting device (2) is varied in time as a function of what is detected by the detection device (8) to thus regulate the density of the layer of compacted ceramic powder (KP).

A system (100) and method to control rheology of ceramic pre-cursor batch during extrusion is described herein. An extrusion system (100) comprises an extruder (122) with an input port (144) configured to feed ceramic pre-cursor batch into a first section (120) of an extruder barrel and a discharge port configured to extrude a ceramic pre-cursor extrudate (172) out of the extruder barrel downstream of the input port (144). A liquid injector (210) is configured to inject liquid into the ceramic pre-cursor batch. A sensor (106) is configured to detect a rheology characteristic of the ceramic pre-cursor batch. A controller (108) is configured (i) to receive the rheology characteristic from the sensor (106), (ii) compare the rheology characteristic to a predetermined rheology value of the ceramic pre-cursor batch, and (iii) generate a command based on the comparison. A liquid regulator (110) is configured to receive the command and adjust liquid flow to the liquid injector (210) based on the command.
