| 20080282961 | Tactile Fire Escape System - A tactile fire escape system for guiding individuals to a fire escape during low visibility emergencies. The tactile fire escape system includes a plurality of first tactile members attached to a wall at a height above a floor, wherein the plurality of first tactile members are comprised of a tapered structure pointing approximately along an emergency path to an exit door, a second tactile sign attached to the exit door, wherein the second tactile sign is comprised of a tapered structure pointing approximately upwardly and a plurality of third tactile members attached to the wall indicating an immediate left or right turn across the hallway or common area. The first tactile members, second tactile sign and third tactile members guide a user along an emergency path toward an exit door. An initial tactile member may also be located within a room to guide the individual toward an initial direction along the emergency path. | 11-20-2008 |

| 20090017729 | POLISHING PAD AND METHODS OF IMPROVING PAD REMOVAL RATES AND PLANARIZATION - A method of improving a removal rate of a pad includes producing a body of a pad of polyurethane from a mix; and introducing into the mix an additive which decreases an elastic rebound of the pad so as to increase a chemical-mechanical planarization removal rate; and using as the additive a substance which at least contains starch. In another embodiment, in a CMP process that includes removing a barrier and buffing a polyurethane after a bulk copper removal process, a polishing pad is used having a shore D hardness less than 35% and having at least one layer made from a mix composed of at least one of a prepolymer with an isocyanate concentration of between 6.5% and 11.0% to achieve a molal concentration, and a monomer in combination with an addition of isocyanate to achieve the substantially same molal concentration. | 01-15-2009 |
