Abstract: A computer-implemented method for precision hyperbolic location fingerprinting, the method comprising, at a computing system, the steps of: (a) receiving measured RSSI values associated with a plurality of fixedly-positioned sensor devices, wherein the plurality of fixedly-positioned sensor devices are stationary in known locations in a 2D environment and caused to transit radio signals to each other and measure characteristics of the received radio signals; (b) generating a raw RSSI fingerprint for each sensor device based on the measured RSSI values; (c) generating a log-ratio RSSI fingerprint between a pair of sensor devices; (d) normalizing the raw RSSI fingerprint and normalizing the log-ratio RSSI fingerprint; (e) combining the raw RSSI fingerprint and the log-ratio RSSI fingerprint to form a fusion RSSI fingerprint; and (f) repeating steps (a) to (e) at predetermined intervals to enhance prediction accuracy of regional fingerprints within the environment.

Abstract: A wayfinding system comprising: a first device comprising at least one sensor for sensing a spatial environment to generate a first map, said a first device positioned in a first position in said spatial environment; a second device for receiving signals from said first device to determine a relative position of said second device within said spatial environment; and wherein on said second device said relative position is used in conjunction with said first map to provide turn-by-turn navigation within said spatial environment.

Abstract: A transponder for sensing a spatial environment for the purposes of creating a local map model of said spatial environment, said transponder comprising: a microprocessor; at least one sensor for scanning said spatial environment and acquiring sensing information about said spatial environment; a memory having instructions executable by said microprocessor to cause the microprocessor to process said sensing information to: determine distance measurements between said transponder and features within said spatial environment; and generate said local map model; a communications interface module coupled to said microprocessor for enabling communication with a first computing device to send said local map model thereto and for enabling communication with a second computing device for using said local map model to navigate said spatial environment.

Abstract: A method for generating a routable map of a spatial environment, the method comprising the steps of: positioning a transponder in a location within said spatial environment at least one sensor; associating at least one sensor with said transponder, said at least one sensor being rotatable in at least one plane; measuring distances within said spatial environment with said at least one sensor relative to said location; and composing a local map model of spatial environment based on said measurements.
