Floor plan deduction using lighting control and sensing
First Claim
Patent Images
1. A method of deducing building floor plan information comprising:
- changing an intensity of light generated from a plurality of lights within a building;
a plurality of light sensors sensing an intensity of light received from at least one of the plurality of lights;
wherein a mobile device includes at least one of the at least one light sensor or the at least one of the plurality of lights; and
whereinthe mobile device communicates with at least one of the at least one light sensor or the at least one of the plurality of lights through changes in patterns of light intensity, wherein the communication allows at least one of the at least one light sensor or the at least one of the plurality of lights to be identified, and location recorded.

Abstract
An apparatus and method of deducing building floor plan information are disclosed. One method includes changing an intensity of light generated from a plurality of lights within a building. A plurality of light sensors senses an intensity of light received from at least one of the plurality of lights. A distance between at least one light sensor and at least one of the plurality of lights is estimated based on the sensed intensity of light.

10. A method of deducing building floor plan information comprising:
-
changing an intensity of light generated from a plurality of lights within a building; a plurality of light sensors sensing an intensity of light received from at least one of the plurality of lights; estimating a distance between at least one light sensor and at least one of the plurality of lights based on the sensed intensity of light; monitoring an up-time of a plurality of lights, and grouping at least a subset of the plurality of lights based on similar up-times, wherein groups of lights are identified as being on a common floor of the building.
