    Abstract: According to examples, an apparatus may include a processor that may access a digital model of an item to be fabricated to have a plurality of features, in which the digital model may include a surface. The processor may pack a plurality of digital ellipsoids to intersect the surface of the digital model of the item, in which the plurality of digital ellipsoids are arranged with respect to each other based on a curvature of the surface. The processor may also determine locations on the surface at which the plurality of digital ellipsoids intersect the surface and may set the determined locations as points on the surface at which the plurality of features are to be formed.

    Abstract: In one example in accordance with the present disclosure, an electronic system is described. The electronic system includes a scanning device to capture an image of an object. The object includes encoded data formed therein. An attribute determiner of the electronic system determines an actual value of a surface attribute of the object. The electronic system includes an extraction device to extract from the image of the object, a target value for the surface attribute from the encoded data. A comparator of the electronic system determines if a difference between the actual value and the target value has a specified value.

    Abstract: In an embodiment, an apparatus includes a projection subsystem to project an image-containing beam, and an image adjustment element. The image adjustment element is to cause adjustment of the image-containing beam in response to a detection of relative movement of the apparatus with respect to a reference object. A method includes determining whether substantial relative movement of a projection system has been detected, in an embodiment. When substantial relative movement has been detected, the method further includes producing control inputs, and altering operation of one or more image adjustment elements and/or altering image data in response to the control inputs, in an embodiment.

    Abstract: Disclosed are embodiments of a system and method for processing an image. An image processing unit (12) includes a processor unit (20) and a control unit (22). The processor unit is configured to receive an incoming video signal. The control unit is configured to generate first control signals that define bit planes manifested on a spatial light modulator (16). The control unit is further configured to generate second control signals that define on and off states for a solid state light source (14). The first control signals impart a reset motion sequence for mirror elements of the spatial light modulator. The second control signals maintain the solid state light source in the off state during at least part of the reset motion.
