Abstract

A hospital location system is disclosed herein. The hospital location system includes a lighting system adapted for the illumination of the hospital, and a controller operatively connected to the lighting system. The controller is adapted to modulate the illumination from the lighting system in a predetermined manner. The hospital location system also includes a sensor configured to sense the illumination from the lighting system. The hospital location system is adapted to identify the location of the sensor based on the manner in which the illumination is modulated. A corresponding method for locating individuals and objects that are within or in close proximity to a hospital is also provided.

Claims

1. A hospital location system comprising:

a lighting system adapted for the illumination of the hospital;

a controller operatively connected to the lighting system, said controller adapted to modulate the illumination from the lighting system in a predetermined manner; and

a sensor configured to sense the illumination from the lighting system;

wherein the hospital location system is adapted to identify the location of the sensor based on the manner in which the illumination is modulated.

2. The hospital location system of claim 1, wherein said lighting system includes light emitting diodes.

3. The hospital location system of claim 1, wherein said lighting system includes incandescent lights.

4. The hospital location system of claim 1, wherein said controller is adapted to modulate the illumination from the lighting system in a manner that is imperceptible to humans.

5. The hospital location system of claim 1, wherein said controller is incorporated into a dimmer operatively connected to the lighting system, said dimmer adapted to selectively regulate the intensity of the illumination.

6. The hospital location system of claim 1, wherein said sensor is integrated into a physiological monitoring device.

7. The hospital location system of claim 1, wherein said sensor includes a transmitter.

8. The hospital location system of claim 7, further comprising a computer wirelessly coupled with the transmitter.

9. A hospital location system comprising:

a plurality of lighting systems configured to respectively illuminate a plurality of hospital regions;

a controller operatively connected to the plurality of lighting systems, said controller adapted to modulate the illumination from the plurality of lighting systems to provide a corresponding plurality of illumination patterns;

a sensor configured to sense one of the plurality of illumination patterns, said sensor including a transmitter configured to send a signal identifying said one of the plurality of illumination patterns; and

a computer adapted to receive the signal from the transmitter, said computer configured to locate the sensor relative to the plurality of hospital regions based on the signal;

wherein the hospital location system provides a single cost efficient system for both location and illumination.

10. The hospital location system of claim 9, wherein said plurality of lighting systems include light emitting diodes.

11. The hospital location system of claim 9, wherein said plurality of lighting systems include incandescent lights.

12. The hospital location system of claim 9, wherein said controller is adapted to modulate the illumination from the plurality of lighting systems in a manner that is imperceptible to humans.

13. The hospital location system of claim 9, wherein said controller is incorporated into a dimmer operatively connected to the plurality of lighting systems.

14. The hospital location system of claim 9, wherein said sensor is integrated into a physiological monitoring device.

15. A method for locating individuals and objects that are within or in close proximity to a hospital:

providing a lighting system adapted to illuminate the hospital;

modulating the illumination from the lighting system in a predetermined manner;

sensing the illumination from the lighting system; and

identifying the location of the sensor based on the manner in which the illumination is modulated.

16. The method of claim 15, wherein said modulating the illumination from the lighting system includes turning the lighting system off and on.

17. The method of claim 15, wherein said modulating the illumination from the lighting system includes varying the frequency of the illumination.

18. The method of claim 15, wherein said modulating the illumination from the lighting system includes modulating the illumination in a manner that is imperceptible to humans.

19. The method of claim 15, wherein said modulating the illumination from the lighting system includes modulating the illumination with a dimmer in a manner adapted to convey a dimmer code.

20. The method of claim 19, wherein said identifying the location of the sensor includes manually inputting the dimmer code into a computer.
