AUTOMATICALLY CALIBRATING ANCHOR DEVICES IN AN INDOOR POSITIONING SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240118368 titled 'AUTOMATICALLY CALIBRATING ANCHOR DEVICES IN AN INDOOR POSITIONING SYSTEM
Simplified Explanation
The abstract describes a patent application for an indoor positioning system using ultra-wideband (UWB) anchor devices to determine the locations of these devices and a client device within the system.
- The indoor positioning system obtains distance measurements between each pair of UWB anchor devices based on round trip time of UWB signals.
- The system determines the location of each UWB anchor device using the distance measurements.
- An absolute network topology of the UWB anchor devices is reconstructed using their determined locations.
- The absolute network topology is used to determine the location of a client device within the indoor positioning system.
Potential Applications
This technology could be applied in various industries such as retail for tracking customer movements, healthcare for monitoring patient locations, and logistics for optimizing warehouse operations.
Problems Solved
This technology solves the problem of accurately determining the locations of devices within an indoor space, which is crucial for applications like asset tracking, navigation, and security.
Benefits
The benefits of this technology include improved accuracy in indoor positioning, enhanced security through better tracking capabilities, and increased efficiency in various operations that rely on location data.
Potential Commercial Applications
Potential commercial applications of this technology include indoor navigation systems for shopping malls, asset tracking solutions for warehouses, and location-based services for smart buildings.
Possible Prior Art
One example of prior art in this field is the use of Bluetooth beacons for indoor positioning systems, which have limitations in terms of accuracy and range compared to UWB technology.
Unanswered Questions
How does this technology handle interference in indoor environments where multiple signals may be present?
The system may utilize signal processing techniques to filter out unwanted interference and ensure accurate distance measurements between UWB anchor devices.
What is the power consumption of the UWB anchor devices and how does it impact the overall system performance?
The power consumption of UWB anchor devices may vary depending on the specific hardware used, but typically UWB technology is known for its low power consumption compared to other wireless technologies.
Original Abstract Submitted
to determine locations of ultra-wideband (uwb) anchor devices in an indoor positioning system, the indoor positioning system obtains distance measurements between each pair of n uwb anchor devices in the indoor positioning system. each distance measurement is determined based on a round trip time of a uwb signal communicated between the pair of uwb anchor devices. the indoor positioning system also determines a location of each of the uwb anchor devices within the indoor positioning system using the distance measurements, and reconstructs an absolute network topology of the uwb anchor devices using the determined locations of the uwb anchor devices. the absolute network topology is used to determine a location of a client device within the indoor positioning system.
