Abstract: Systems and methods for controlling a material extrusion device to extrude a filament of an ink are provided. An extrusion printing control system collects from one or more sensors measurements representing an internal state of material extrusion processing during extrusion of the filament. In addition, the system collects an image of the filament as the filament is extruded. The system applies a classifier to the collected image to generate an image-derived state characterizing the filament. Based on the internal state and the image-derived state, the system estimates a derived state using a model. The system determines control parameters using the model to achieve a desired quality of the filament by minimizing a cost function based on the internal state, the image-derived state, the derived state, and constraints of the material extrusion device. Finally, the system provides the control parameters to a controller of the material extrusion device.

Abstract: In one embodiment, a method includes depositing a material on a substrate. The material includes: a plurality of particles configured to complete a self-propagating and/or self-sustaining reaction upon initiation thereof, a solvent system, and one or more stabilizing agents.

Abstract: In one embodiment, a method includes dispersing a plurality of particles in solution to form a dispersion and adding a stabilizing agent to the dispersion in an amount sufficient to cause the dispersion to exhibit one or more predetermined rheological properties. The particles in the dispersion are configured to complete a self-propagating and/or self-sustaining reaction upon initiation thereof. In another embodiment, a method includes depositing a material on a substrate. The material includes: a plurality of particles configured to complete a self-propagating and/or self-sustaining reaction upon initiation thereof, a solvent system, and one or more stabilizing agents.

Abstract: In one embodiment, a method includes dispersing a plurality of particles in a solution to form a dispersion; and adding a stabilizing agent to the dispersion in an amount sufficient to cause the dispersion to exhibit one or more predetermined rheological properties, wherein the particles are characterized by a core-shell configuration, wherein the core-shell configuration includes a core formed from a first material and a shell formed from a second material, wherein the first material and the second material form a combustible composition and/or a reactive binary composition that is configured to complete a self-propagating reaction and/or a self-sustaining reaction upon initiation thereof. Corresponding materials, and methods of using such materials, are also disclosed.

Abstract: The present disclosure relates to segmented shielding using wirebonds. In an exemplary aspect, a shield is formed from a series of wires (e.g., wirebonds) to create a wall and/or shielded compartment in an integrated circuit (IC) module. The wires can be located in any area within the IC module. The IC module may be overmolded with an insulating mold compound, and a top surface of the insulating mold can be ground or otherwise removed to expose ends of the wires to a shield layer which surrounds the insulating mold. Some examples may further laser ablate or otherwise form cavities around the ends of the wires to create stronger bonding between the wires of the shield and the shield layer.
