Abstract: The present invention provides an adhesive made from a reaction product of: (a) a polymerizable monomer derived at least in part from non-petroleum resources; (b) an initiator; (c) a polymeric stabilizer, wherein the reaction occurs in water to yield a microsphere adhesive. The microsphere adhesive can be formulated into a pressure sensitive adhesive composition that can be applied to various substrates such as paper and polymeric film to produce repositionable adhesive coated articles such as tapes, notes, flags, easels and the like.
Abstract: A communication article and system comprising a writing member having a dry erasable front surface and a projection member is disclosed. The projection member includes an asymmetric optical diffuser that scatters light in a first direction with a first viewing angle AH, and in a second direction orthogonal to the first direction with a second viewing angle AV. The ratio AH/AV is at least about 2.

Abstract: A task lighting apparatus produces glare-free illumination of a work area. The apparatus includes a shade defining a cavity having an opening, a light source positioned to emit light into the cavity, and a glare control member disposed within the opening wherein the diffuser comprises a louvered array of dual brightness enhancement film.
Abstract: An ultraviolet radiation-polymerizable composition comprises (a) an acrylated monounsaturated fatty acid alkyl ester, (b) a monoethylenically unsaturated (meth)acrylic acid ester of a non-tertiary alkyl alcohol, and (c) a photoinitiator.
Abstract: A device for treatment of plantar fasciitis and/or Achilles tendonitis comprises (a) a calf strap removably engagable to the calf of a leg, (b) a foot assembly removably engagable to the foot of the leg such that when the device is worn the assembly can be positioned proximate to the ball of the foot intermediate to the midfoot and forefoot areas of the foot to secure it to the foot, and (c) a substantially inelastic tension member connectable between the calf strap and the foot assembly in a tensioned manner such that when the device is worn the plantarflexion of the ankle is limited such that the plantar surface of the foot is held in a neutral to slight dorsiflection.
