This application claims the benefit of U.S. Provisional Application No. 60/920,368 filed Mar. 27, 2007 and is a continuation in part of U.S. patent application Ser. No. 11/018,947 filed Dec. 21, 2004 and is a continuation-in-part of U.S. patent application Ser. No. 11/251,733 filed Oct. 17, 2005. U.S. patent application Ser. No. 11/018,947 filed on Dec. 21, 2004 claims the benefit of U.S. Provisional Application No. 60/619,340 filed Oct. 15, 2004 and is a continuation-in-part of U.S. patent application Ser. No. 10/638,878 filed on Aug. 11, 2003, which claims the benefit of U.S. Provisional Application No. 60/403,790 filed on Aug. 15, 2002. U.S. patent application Ser. No. 11/251,733 filed on Oct. 17, 2005 claims the benefit of U.S. Provisional Application No. 60/619,340 filed Oct. 15, 2004 and claims the benefit of U.S. Provisional Application No. 60/690,762 filed Jun. 15, 2005. The contents of all are incorporated herein by this reference.
Later, modular floor coverings utilized smaller, uniform size modules or tiles in both solid surface floor coverings such as vinyl tiles and in textile-faced floor coverings, usually called carpet tiles. As explained in U.S. Patent Application Publication (incorporated by reference), tiles may be installed as area rugs that do not cover the entire flooring surface. However, the vast majority of tiles are used in wall-to-wall installations. Tiles have traditionally been installed in aligned rows and columns, with the edges of each tile aligned with the edges of adjacent tiles (“conventional carpet tile installation method”). Conventional carpet tile has historically been a product that sought to mimic the appearance of broadloom carpet and to hide or at least de-emphasize the fact that the product was modular. Achieving this result has required, at minimum, that carpet tiles or modules be placed in a flooring installation with the same orientation that the modules had at the time they were produced (i.e., monolithically). However, textile face modular flooring designers have recently begun to design flooring and flooring installations that do not seek to mask, but rather celebrate, the modularity of the flooring. For instance, while still installed in aligned rows and columns, modules are installed “quarter-turned” with each tile position rotated 90� relative to each adjacent tile. Moreover, carpet tiles have been developed that can be installed “randomly” without regard to position or rotational orientation as described in U.S. Pat. No. 6,908,656, which is incorporated herein by reference.
In another embodiment of the invention, a stack of connectors each having adhesive on one side are bonded or otherwise attached together. The individual connectors in the stack of connectors may be bonded or attached together in a variety of ways. For example, the adhesive on the adhesive side of one connector may be releaseably attached to an adjacent connector's opposite side that may be coated with a release coating to prevent the adhesive from forming a permanent or hard-to-detach bond. Generally, the adjacent connectors in a stack are oriented in a similar direction and aligned. As another example, a release layer may separate the adjacent connectors, with the adhesive layer of a first connector attached to a release material and the opposite side of a second connector also attached to the release material. As yet another example, the stack of connectors may be successive connectors attached on a single strip of release material folded such that adjacent connectors on the strip overlap one another in the stack, i.e. fan folded release material. A stack of connectors may also be included within a dispenser that assists a user in removing an individual connector from the stack of connectors. During carpet installation, a carpet installer may use a stack of connectors by removing an individual connector from the stack and attaching it to the underside of the carpet edge.
In yet another embodiment, the connectors can be equipped as radio frequency identification (“RFID”) tags by including radio frequency transponders. A radio frequency transponder is any kind of radio transmitter and/or receiver that is activated when it receives a radio frequency signal. The transponders can be incorporated within or otherwise attached to a connecter in any manner. One or more transponders may be imprinted on one or more connectors used in an installation, as examples, a transponder could be imprinted on either side of the film or on an inlay that is attached to the film of a connector. It is not necessary, however, to have a transponder on every connector in an installation. Various configurations may be used including those depicted in the Figures.
Alignment indicia 330 (including, but not limited to, crosshairs, lines, dots, blocks, and multi-color segments and quadrants) may be provided on the connector 320 to provide guidance for an installer wishing to position the connector 320 at a corner or edge of a carpet tile. A connecter may be positioned at a corner, at an edge, or simply on the back of a tile. In a multi-tile installation, some connectors may span the edges of adjacent tiles and others may simply be placed on the tile backs, i.e., each attaching to a single tile.
In one application, the radio frequency transponders serve a mapping function to guide equipment equipped with a radio frequency component reader. For example, a reader can be placed on a vacuum cleaner or other cleaning machine. The reader may be programmed with a sequence of unique transponder numbers that are on the connectors in a room. When a robotic vacuum is so programmed and activated, the radio frequency transponders on the connectors in the room may be read by the robotic vacuum's reader and used to guide the vacuum towards the connectors in the order that the connectors' transponder numbers appear in a programmed sequence. In this way, the entire floor can be automatically cleaned or otherwise maintained. The transponder numbers of connectors positioned in higher traffic areas can appear more often in the sequence to ensure that those areas are cleaned more thoroughly. A variety of radio transponder readers may be used including readers offered by APSX, LLC� and Skyetek, Inc.�
Transponders can also be used to monitor the location and/or movement of equipment. In one embodiment, hospital equipment is equipped with a reader. The location of each piece of equipment in the hospital can be determined when its reader reads a connector transponder number, which is different from the other connector transponder numbers. In another embodiment, movement of equipment, such as a vacuum, can be monitored to determine whether an area has been cleaned or not. For example, the reader on a vacuum (either manually or robotically driven) can either store (to be downloaded at a later time) or transmit (via wireless communication) to a control system the connector transponder numbers that it reads in a room. If a transponder number on a connector in the room is not read, then the vacuum obviously did not clean in the vicinity of the connector. In this way, information about the cleaning history of a room can be recorded.
