Abstract

A method and system for identifying panels that embed active and passive components of an electronic device, or that hide certain key components of a building'"'"'s infrastructure in the plenum of the ceiling. In one aspect, a panel is provided with a phosphorescent or other light-responsive indicia that is representative of an object hidden within the panel or that is part of the building infrastructure hidden by a plurality of panels. A panel having a device embedded within it is identified by first placing a light-responsive indicia on the panel that is representative of the devices stored therein or the building infrastructure lying above it. The panel is then irradiated and the light-responsive indicia observed. In another aspect, a panel having an embedded object is provided with an indicator device that is embedded in the same panel. The indicator detects a query signal emitted by a scanner, compares the detected signal with information stored in the memory of the indicator, and if a match is found, emits a visible or audible signal from a signal output device into the room below. The signal output device can be a light emitting diode or a sound generator.

7. The surface covering system of claim 1 wherein the plurality of panels are ceiling tiles.

8. The surface covering system of claim 1 wherein the scanner is a programmed multiple frequency scanner that generates the query signal at a specific frequency according to the type of object being located.

9. The surface covering system of claim 2 wherein the embedded object is an electronic communication device that communicates wirelessly with at least one electronic device located in a room interior.

10. The surface covering system of claim 1 wherein the scanner is a portable, hand-held unit.

11. The surface covering system of claim 1, wherein the object is hidden behind the at least one of the plurality of panels.

12. The surface covering system of claim 11, wherein the hidden object is part of the building infrastructure.

13. The surface covering system of claim 12, wherein the hidden object is selected from the group consisting of a plumbing fixture, an electrical fixture, a component of a heating ductwork, a component of ventilating ductwork and a component of air conditioning (HVAC) ductwork.

14. The surface covering system of claim 9, wherein the electronic communication device is selected from the group consisting of a communication bus, a transmitter/receiver and an antenna.

15. A method for identifying and locating an object hidden by a surface covering, the method comprising the steps of:

providing a plurality of similar panels;

storing identifying information for the hidden object in a memory of a transmitter/receiver device embedded in one of the plurality of panels;

emitting a query signal by a scanner device to interrogate the embedded transmitter/receiver device at a frequency intended to activate a response;

comparing the query signal to the identifying information of the hidden object; and

generating a detectable output signal if the query signal matches the identifying information of the hidden object.

16. The method of claim 15 further comprising receiving an identification and a location of the hidden object by an observer in a room interior.

17. The method of claim 15 wherein the transmitter/receiver device is selected from the group consisting of a radio frequency identification (RFID) transponder and an infrared (IR) transponder.

18. The method of claim 15 further comprising storing information in the memory of the transmitter/receiver device which identifies the location of the hidden object.
