    Abstract: Disclosed is a method for organizing a substantially uniform system of colorimetry comprising the steps of (i) taking a pseudoinverse of a matrix containing intensity values for an existing non-uniform color-matching functions; (ii) optionally normalizing the pseudoinverse matrix from step (i); (iii) empirically determining an opponency transformation matrix based on a plurality of substantially uniformly spaced color standards; (iv) transforming the matrix from step (ii) to a color opponency color coordinate utilizing the opponency transformation matrix from step (iii) to obtain a Red-Green, Yellow-Blue and Lightness (RG, YB and LT) color matching functions; and (v) transforming the RG, YB and LT color matching functions from step (iv) non-linearly to color matching functions that produce colors recognizable as being uniform by human vision; wherein after step (v) the existing non-uniform color matching functions are transformed into substantially uniform color matching functions.

    Abstract: A hanger for connecting a structural component to a wall that can have sheathing mounted thereon either before or after the hanger is connected to the wall. The hanger includes a channel-shaped portion configured to receive the structural component. An extension portion extends from the channel-shaped portion and is configured to extend through the sheathing to engage the wall at a first location. A connection portion is configured for attachment to the wall at a second location spaced from the first location.

    Abstract: A doffing apparatus can be configured to couple to an automatically guided vehicle (AGV). The doffing apparatus can comprise at least one elongate arm, each elongate arm having a proximal end, a distal end, and a length, and at least one driver, each driver being configured to move along a respective elongate arm to move a bobbin toward the distal end of the elongate arm. The doffing apparatus can further comprise at least one alignment device. The doffing apparatus can further comprise a processor, wherein the processor is configured to: receive feedback from the at least one alignment device, provide a control signal to cause the AGV to align the elongate arm with a receptacle at a loader, and move the driver a select distance along the length of the elongate arm.

    Abstract: Disclosed herein is an aqueous latex composition comprising a substantially acrylic core-shell latex, wherein a water-retaining monomer is copolymerized to the shell. The Tg of the core ranges from about 0° C. to about 12° C., and the Tg of the shell ranges from about 13° C. to about 40° C. The mean volume average particle size of the latex ranges from about 125 nm to about 200 nm. The core-shell latex comprises at least one acrylic monomer having a solubility that ranges about 10 g/L to about 30 g/L at 30° C., and this at least one acrylic monomer is present in the shell polymer in an amount greater than about 50 wt. % of all monomers in the shell. Preferably, the at least one acrylic monomer is methyl methacrylate.

    Abstract: A tufted article having a backing material and a plurality of tufts. The plurality of tufts can include cut tufts having first and second tuft portions projecting from a face surface of the backing material. The first and second tuft portions of each cut tuft have respective pile heights relative to the backing material. Each cut tuft also has a backstitch that joins the first and second tuft portions and extends across a portion of a back surface of the backing material. The plurality of tufts includes a plurality of asymmetric cut tufts that have first and second tuft portions with unequal pile heights. Systems and methods for making tufted articles having asymmetric cut tufts are also disclosed.

    Abstract: Methods and systems are disclosed for analyzing one or more images of a textile to determine a presence or absence of defects. In one example, an image of at least a portion of a textile may be obtained and compared to a reference image of a reference textile. Based on the comparison, one or more areas indicative of a height variation between the textile and the reference textile may be determined. An action may be performed based on the one or more areas indicative of the height variation.
