  • Detectable warning system with field thermoplastic application
    Patent number: 7740413
    Abstract: A detectable warning system, for tactilely signaling the presence of a terrain transition to a pedestrian, using a plurality of detectable warning domes that are arranged in a grid within a warning dome tiles. The warning dome tiles comprises heat resistant detectable warning domes and connecting surface. A base layer sheet of thermoplastic is applied and adhered to the pavement surface prior to the application of the detectable warning tiles. A top layer of thermoplastic is applied and adhered to, and conformed to the warning domes. The detectable warning domes protrude from the pavement surface in an evenly spaced pattern that is detectable by the pedestrian using a cane or other guidance instrument.

  • Document displaying system
    Patent number: 7219460
    Abstract: A document displaying system for facilitating easy access to documents being displayed. The document displaying system includes a support assembly having a backing member selectively couplable to a vertical support surface; a frame assembly operationally couplable to the support assembly; a transparent cover member operationally couplable to the frame assembly, and abutting a perimeter edge of the transparent cover member; and a pair of magnetic coupling members for selectively operationally securing the transparent cover member to the support assembly.

  • Detectable warning system
    Patent number: 7142095
    Abstract: A detectable warning system, for tactily signaling the presence of a terrain transition to a pedestrian, using a plurality of detectable warning domes that are arranged in a grid within a detectable warning carrier assembly. The detectable warning carrier assembly comprises a carrier layer being one of a top layer and a base layer of thermoplastic material with heat resistant detectable warning domes therebetween. The carrier layer is heated and adhered to a pavement surface. The detectable warning domes protrude from the pavement surface in an evenly spaced pattern that is detectable by the pedestrian using a cane or other guidance instrument.
