  • Patent number: 9993076
    Abstract: A movable table assembly includes a base, a vertical support, and a table. The base includes a longitudinal frame member and at least one wheel. The vertical support connects with the base at either a first mounting location adjacent a first end of the longitudinal frame member or a second mounting location adjacent a second, opposite, end of the longitudinal frame member. The table connects with the vertical support and is vertically offset from the base. The table extends away from the vertical support toward the second end of the longitudinal frame member when the vertical support is connected with the base at the first mounting location. The table extends away from the vertical support toward the first end of the longitudinal frame member when the vertical support is connected with the base at the second mounting location.

  • Patent number: 8015970
    Abstract: A personal safety protective device that includes a lens and a support structure onto which the lens is secured. The lens includes a substrate and a hard-coat layer located on the substrate of the lens. The hard-coat layer has a low surface energy outer surface that is derived from a) an additive that includes at least one of i) a perfluoropolyether urethane that includes hydrolysable silane groups, and ii) an acrylate polymer that includes at least one perfluoropolyether moiety and at least one hydrolysable silane group, and b) a silsesquioxane-based hard-coat composition. The provision of such a lens on a personal safety protective device enables the lens to be durable to abrasion and to be easily cleaned without use of solvents that could shorten the service life of the lens.
