Abstract: Systems, methods, logic, and devices may support shoe design through 2.5-dimensional (2.5D) shoe models. In some examples, a system may include a 2D shoe shell pattern engine configured to access a 2D shoe shell pattern, the 2D shoe shell pattern generated for shoe design. The system may also include a 2.5D shoe model engine configured to generate a 2.5D shoe model by placing shoe design elements provided by a user onto the 2D shoe shell pattern of the shoe, including by adding 2.5D layering data for each shoe design element placed on the 2D shoe shell pattern to form the 2.5D shoe model, and wrap the 2.5D shoe model into a 3D shoe model for construction of a physical shoe from the 3D shoe model.

Abstract: A system may support augmented reality (AR)-based layup of plies to form a composite laminate. The system may include an AR headset configured to drive an AR view that digitally visualizes ply placement data on a composite part layup tool physically visible through the AR headset. The system may also include an AR ply layup engine AR ply layup engine configured to analyze a view of the AR headset to identify the composite part layup tool, obtain ply placement data, and provide ply placement data to the AR headset to digitally overlay on the composite part layup tool physically visible through the AR headset.

Abstract: A diaphragm chamber molding apparatus and method including a chamber for containing a mold surface therein; a bottom flexible diaphragm placed over and sealable with respect to the top of the chamber; a top flexible diaphragm placed over and sealable with respect to the bottom diaphragm for containing a lay-up between the top and bottom diaphragms; means for evacuating the area between the top and bottom diaphragms; and means for drawing the top and bottom diaphragms and the lay-up therebetween down over a mold surface located in the chamber to form the lay-up.

Abstract: Sensors for measuring properties of resinous materials having an insulating member bonded directly to a conductive strand and a narrow thread-like geometry in which only a very small surface area of the connecting strand is exposed. The sensors provide advantages in the variety of environments in which measurements can be made, in the variety of types of measurements that can be made, and in the ease of constructing the sensors and in making the measurements.

Abstract: Method and apparatus for nondestructively removing a cut segment of predetermined shape from a limp material sheet workpiece and transporting the cut workpiece segment to a staging area for further processing. The cut segment is picked up by a picker which may comprise an array of carding strips, each strip having a plurality of needle-like elements, arranged such that each strip can be displaced relative to its adjacent strips and the needle-like elements of each strip are angularly offset with respect to the needle-like elements of the adjacent strips. Such removal and transporting having is accomplished without distorting the shape of the cut segment.

Abstract: A resin transfer molding system including a sealable chamber having opposing flexible diaphragms forming an outer reconfigurable tooling surface and an inner surface surrounding a workpiece including fibrous reinforcing material to be impregnated and formed over a mold surface. There are means for impregnating the fibrous reinforcing material and means for compressing the diaphragms about the fibrous reinforcing material and for urging the compressed diaphragms and the fibrous reinforcing material contained therein over the mold surface to conform the compressed diaphragms and the fibrous reinforcing material to the contours of the mold surface.

Abstract: A disposable self contained cartridge for resin transfer molding including a sealable flexible-walled vacuum bag surrounding fibrous reinforcing material to be impregnated and formed and a quantity of resin for impregnating the fibrous reinforcing material, and vacuum port to collapse the vacuum bag about the fibrous reinforcing material and the resin.

Abstract: A reconfigurable fiber-forming resin transfer molding system including a sealed chamber with first and second spaced flexible diaphragms for holding a fiber workpiece and press and die mold surfaces for forming the fiber workpiece.

Abstract: Means including a single comparatively low-power laser and cooperative optics are disclosed for both designating and boresighting a comparatively high-power laser with an intended target object.

Abstract: A low diffraction-feedback high-energy laser system includes an injection laser, and a master power amplifier (MOPA). The master oscillator power amplifier preferably includes a convex and a concave cavity reflector. A sensor mounted to the convex reflector is operative to provide a signal indication of cavity turbulence.

Abstract: An apparatus for controlling the shape of an elongated flexible spline to substantially match a third order polynomial curve extending between first and second end points where the spline extends along a deformable central axis. A spline support member extends along the central axis. The spline is pivotably coupled to the support member at a first point along said central axis, and is slidingly coupled to the support member at second, third and fourth points along the central axis. The support member establishes a first predetermined distance (L) along a reference line passing through the interior two of said first, second, third and fourth points. A first spline deflector selectively deflects one of the exterior two of the first, second, third and fourth points by a distance D.sub.L in a direction perpendicular to the reference line. A second spline deflector selectively deflects the other of the exterior two of the first, second, third and fourth points by a distance D.sub.
