Abstract: A team of robots may fabricate a tubular structure. Each robot may fabricate a tube by winding resin-covered fiber around an inflated, cylindrical mandrel of the robot. The resin may cure, resulting in a hardened tube segment The robot may extend the tube by fabricating additional segments of the tube, one segment at a time. After a first segment cures, the mandrel may deflate, then the robot may move up inside the tube, then the mandrel may inflate, and the robot may begin fabricating another tube segment. After completing a tube segment, the robot may tilt relative to that segment, before starting the next segment. By doing so, the robot may cause the tube to be curved. A computer may guide the team of robots during fabrication of the tubes, by executing a flocking algorithm. The algorithm may prevent collisions with already fabricated tube segments.

Abstract: In illustrative implementations of this invention, a crucible kiln heats glass such that the glass becomes or remains molten. A nozzle extrudes the molten glass while one or more actuators actuate movements of the nozzle, a build platform or both. A computer controls these movements such that the extruded molten glass is selectively deposited to form a 3D glass object. The selective deposition of molten glass occurs inside an annealing kiln. The annealing kiln anneals the glass after it is extruded. In some cases, the actuators actuate the crucible kiln and nozzle to move in horizontal x, y directions and actuate the build platform to move in a z-direction. In some cases, fluid flows through a cavity or tubes adjacent to the nozzle tip, in order to cool the nozzle tip and thereby reduce the amount of glass that sticks to the nozzle tip.

Abstract: An ion source generating ions by matrix-assisted laser desorption/ionization (MALDI) comprising a MALDI sample support and a solid-state the laser system generating a pulsed laser beam, which has a wavelength in the range between 332 and 342 nanometers and is spatially shaped in the solid-state laser system such that the spatial intensity distribution of the laser beam on the MALDI sample support exhibits more than one intensity peak.

The invention consists in providing an adjustable laser system which, in one setting, generates a single intensity peak on the sample and, in another setting, a multiplicity of intensity peaks, with the half-width, intensity, spatial arrangement and/or degree of spatial modulation of the single intensity peak and/or the intensity peaks being adjustable.

The invention consists in providing a laser system which generates a spatially modulated intensity distribution with intensity spots on the sample, which significantly improves the quality and the robustness of the mass spectrometric analysis compared with a spatially homogeneous intensity distribution and, in particular, improves the ionization efficiency and, for a time-of-flight mass spectrometer with axial injection, the mass resolution and the signal-to-noise ratio.
