BARRIER TYPE DETECTION USING TIME-OF-FLIGHT AND RECEIVE SIGNAL STRENGTH INDICATION - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17731504 Titled 'BARRIER TYPE DETECTION USING TIME-OF-FLIGHT AND RECEIVE SIGNAL STRENGTH INDICATION'
Simplified Explanation
This abstract describes techniques for using wireless devices to detect and classify barriers between devices. The method involves measuring round trip time and received signal strength of radio frequency signals exchanged with wireless nodes to determine the state of the physical environment. By comparing the measurements from different sets of signals, the method can detect changes in the physical environment and provide an indication of the state change.
Original Abstract Submitted
Techniques are provided for utilizing wireless devices to detect and classify barriers between devices. An example method for detecting a change in state of a physical environment includes determining a first state of the physical environment based on one or more round trip time measurements and one or more received signal strength measurements associated with a first plurality of radio frequency signals exchanged with one or more wireless nodes; determining a second state of the physical environment based on one or more round trip time measurements and one or more received signal strength measurements associated with a second plurality of radio frequency signals exchanged with the one or more wireless nodes; and providing an indication of a state change in the physical environment based at least in part on a comparison of the first state and the second state.
