US Patent 11010501 Monitoring users and conditions in a structure

Methods and apparatus include those used to monitor a position of a user in or proximate to a structure and the conditions in the structure while the user is present. Methods and apparatus may further orient the user in the structure to guide the user to locations or items of interest and using a virtual model, the user's smart device may provide information about the structure to the user. Precise locations of the user, conditions measured, and items therein may be quantified via simplified X, Y and Z coordinate determination and/or a determined direction of interest.
