  • Patent number: 11298912
    Abstract: A pre-assembled kit of cut shapes disposed upon a peelable or repositionable adhesive by means of an affixing adhesive protected by a water-soluble coating which is solubilised either prior to and/or on application of the kit to a surface which may be moistened prior to application. When the water-soluble coating is solubilised, in whole or in part, by placing in contact with the moistened surface, it will expose and/or activate, in whole or in part, the pressure-sensitive adhesive beneath the water-soluble coating to the surface to which it is to be applied and the pre-assembled kit will become affixed to the surface. Alternatively, solubilisation of the water-soluble coating may be provided by applying water, preferably warm water, to the water-soluble coating prior to applying the pre-assembled kit to the surface. A method of producing the pre-assembled kit of cut shapes is provided.

  • Patent number: 8615912
    Abstract: A method and system for an illuminated display. The display can include a first image that may be illuminated by a light source and a second image that may be illuminated by a light source. The light source may be a plurality of light emitting diodes (LEDs) and the LEDs and uniform illumination may be achieved through the use of waveguides. Additionally, the display may be such that it is flexible and that it may be mounted in any of a variety of locations and onto any of a variety of objects.
