    摘要： Color shifting retroreflective articles can provide features such as decorative effects, evidence of tampering, security authentication or positional information. In some embodiments, the color shifting retroreflective article includes a layer of microspheres, and a reflective coating that is disposed in optical association with the layer of microspheres. The reflective coating includes a spacer layer disposed between a semitransparent first reflective layer and a second reflective layer. The first reflective layer includes a reflective layer disposed adjacent the layer of microspheres. At least one layer of the reflective coating includes a non-uniform thickness associated with each of a plurality of microspheres such that light incident on the article from a first direction is retroreflected at a first color and light incident on the article from a second direction is retroreflected at a second color visibly different from the first color.

    摘要： A ball throwing practice system for improving a ball player's skills that includes a collapsible support frame having a first pair of legs and a second pair of legs, with the second pair of legs being pivotally coupled to one of the first pair of legs to permit pivoting of the second pair of legs with respect to the first pair of legs. The system also includes a target assembly secured to the support frame for defining a passage therethrough for representing a zone for an accurately thrown ball to pass through. Preferably, the target assembly comprises a pair of substantially horizontally oriented plate members disposed in a spaced relationship, with a lower one of the plate members being located below an upper one of the plate members. The lower plate member may be suspended below the upper plate member by a plurality of cords. Each of the plate members may have a central aperture therethrough which is defined by an inner perimeter of each plate member, and an outer perimeter of each plate member may be substantially parallel to the inner perimeter.

    摘要： Microspheres comprise a polymer including one or more of 1) a plurality of C3 or larger alpha-olefin units wherein the C3 or larger alpha-olefin units are incorporated into the polymer so as to give an average number of less than one branch point per C3 or larger alpha-olefin unit, 2) a plurality of C2 alpha-olefin units wherein the C2 alpha-olefin units are incorporated so as to give an average number of branch points greater than 0.01 per C2 alpha-olefin unit, and 3) cyclopentene or substituted cyclopentene, the microspheres having an average diameter in the range of 1 to 300 micrometers. Optionally, the polymer of the microspheres can be crosslinked. The microspheres can be prepared by suspension or dispersion polymerization processes using aqueous or organic reaction media. Powder coatings can be prepared from the microspheres.
