Abstract: According to one aspect, there is provided a method of selectively solidifying successive layers of build material in a 3D printing system. The method comprises obtaining data relating to a 3D object to be generated, forming a layer of build material on a build platform, applying to the formed layer a pattern of fusing agent corresponding to a portion of the layer to be solidified to form a layer of the object, applying to the formed layer a pattern of anti-caking agent on portions of the formed layer that are not to be solidified to form a layer of the object, and applying energy to the whole of the formed layer to cause portions of the layer on which fusing agent was applied to heat up, melt, coalesce, and then solidify upon cooling, and to cause portions of the formed layer on which anti-caking agent was applied to control caking of build material in those portions.

Abstract: Methods and apparatus are provided related to fluid dispensing heads. A dispense head is formed to define a plurality of fluid jetting nozzles and a surface pattern. The surface pattern is characterized by one or more voids extending inward from an outer surface of the dispense head. Fluid puddle formation during operation of the dispense head is limited in volume by way of the surface pattern. Fluid puddle limiting reduces or eliminates dispensing errors to an entity, undesirable artifacts from resulting on a printed media, or similar problems.

Abstract: A system for producing a composite image in a multiple projection system includes at least two projectors, a dynamic image shifting mechanism, associated with at least one of the two projectors, and a controller, connected to control each projector and the image shifting mechanism. Each projector is configured to project a component image to a projection surface at an image refresh rate, and the dynamic image shifting mechanism is configured to shift a projection path of the component image of the at least one projector. The controller is configured to modify image data sent to the at least one projector and to shift the dynamic image shifting device to produce a single composite image comprising the at least two component images.

Abstract: A method of displaying an image with a display device includes receiving image data for the image. Sub-frame shifting parameters are identified based on at least one of image characteristics of the image, system status information, and user-defined parameters.

The fuse structure includes a first region adapted to be coupled to a voltage source, a second region adapted to be coupled to a ground, and a current flow region disposed between the first and second regions. The current flow region has a configuration that causes a void to be opened at a point of localized heating due to current crowding within the current flow region and that causes the void to propagate across the current flow region.
