    Abstract: The disclosure provides an apparatus that includes: a stage defining a build plane; a micro light emitting diode (μLED) array including multiple pixels and configured to emit ultraviolet (UV) light towards the build plane; a two-dimensional (2-D) voice coil manipulator mechanically coupled to the μLED array and configured to align the pixels of the μLED array with the build plane; and a control module programmed to cause the μLED array to illuminate a UV curable material at the build plane to form a stack of layers of the three-dimensional object, wherein the apparatus adjusts a UV illumination pattern for the layers of the UV curable material by varying an output intensity of UV light from the pixels of the μLED array and by varying an alignment between the μLED array and the build plane using the 2-D voice coil manipulator.

    Abstract: An apparatus includes a holder to support an indenter relative to a sample, a depth sensor, and a controller. The operations include applying a first force on the sample with the indenter and determining a first depth of the indenter based on data generated by the sensor, moving the indenter from the first depth to a greater predetermined depth, then applying the first force on the sample with the indenter and determining a second depth of the indenter based on second data generated by the sensor, and determining a value indicative of hardness of the sample based on a difference between the first depth and the second depth. The apparatuses described can use a single scale for hardness that enables hardness values for different materials to be compared to one another.

    Abstract: A vacuum deposition system includes a vacuum deposition chamber having multiple regions defined therein; a carousel disposed in the vacuum deposition chamber, the carousel configured to hold multiple substrates, the carousel rotatable around a central spindle; a deposition source positioned to deposit material onto a substrate located in a deposition region of the vacuum deposition chamber; and multiple heating elements disposed in the vacuum deposition chamber in a fixed position relative to the central spindle, each heating element being controllable separately from each other heating element, wherein each heating element is positioned to apply heat to a corresponding region of the vacuum deposition chamber.

    Abstract: A method that includes: providing a substrate including a layer of a crystalline material having a first surface; and exposing the first surface to an environment under conditions sufficient to cause epitaxial growth of a layer of a deposition material on the first surface, wherein exposing the first surface to the environment includes illuminating the substrate with light at a first wavelength while causing the epitaxial growth of the layer of the deposition material. The first surface includes one or more discrete growth sites at which an epitaxial growth rate of the quantum confined nanostructure material is larger than areas of the first surface away from the growth sites by an amount sufficient so that the deposition material forms a quantum confined nanostructure at each of the one or more discrete growth sites.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for changing a distributed mode loudspeaker's fundamental frequency. One of the systems may include a light emitting diode display that includes an array of pixels, each pixel including, for each color of multiple colors, a directional light emitter and a wide-angle light emitter, a first combination of all the directional light emitters configured to generate a first display image viewable within a first viewing angle, and a second combination of all the wide-angle light emitters configured to generate a second display image concurrently with the generation of the first display image that is viewable within a second viewing angle. The first display image is a different image than the second display image and the first viewing angle is a narrower viewing angle than, and included within, the second viewing angle.

    Abstract: A method for producing an experimental output satisfying an objective includes conducting an experimental execution process including applying a selection criterion to select an approach to determining a set of parameters for a set of experiments, and determining a first set of parameters for a first experiment according to the selected approach based on one or more of (i) a predicted relationship between a set of parameters and a characteristic of a corresponding experimental output, (ii) the measured characteristic of a second experimental output from a second experiment executed according to a second set of parameters, (iii) the objective, and (iv) a parameter selection rule. Conducting an experimental execution process includes controlling execution of the first set of experiments according to the first set of parameters, where execution of each first experiment includes conducting the experiment according to the first set of parameters to produce a first experimental output; and measuring the characteristic of the first experimental output. The method includes determining whether the objective is satisfied by the experimental execution process, and, when the objective is not satisfied by the experimental execution process, conducting a subsequent experimental execution process.
