METHOD AND APPARATUS FOR INDOOR POSITIONING USING RANGING AND SENSING INFORMATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240125916 titled 'METHOD AND APPARATUS FOR INDOOR POSITIONING USING RANGING AND SENSING INFORMATION
Simplified Explanation
The abstract describes an indoor positioning method that utilizes registered Wi-Fi nodes, ranging operations, sensor readings, and filtering operations to estimate the position of a device.
- Scanning for registered Wi-Fi nodes with known coordinates
- Performing ranging operations with selected nodes to generate distance measurements
- Obtaining sensor readings from inertial measurement units (IMUs)
- Estimating device position using distance measurements and sensor readings through filtering operations
Potential Applications
This technology could be applied in indoor navigation systems, asset tracking in warehouses, and location-based services in shopping malls.
Problems Solved
This technology solves the problem of accurate indoor positioning without relying solely on GPS signals, which may be weak or unavailable indoors.
Benefits
The benefits of this technology include improved accuracy in indoor positioning, enhanced user experience in indoor navigation, and increased efficiency in asset tracking.
Potential Commercial Applications
Potential commercial applications of this technology include indoor mapping services, smart building management systems, and location-based advertising platforms.
Possible Prior Art
One possible prior art could be the use of Bluetooth beacons for indoor positioning, which may not provide the same level of accuracy as the method described in the patent application.
Unanswered Questions
How does the method handle obstacles or signal interference in indoor environments?
The patent abstract does not specify how the method addresses obstacles or signal interference that may affect the accuracy of the positioning estimation.
What is the power consumption of the device when using this positioning method?
The abstract does not mention the power consumption implications of implementing this indoor positioning method on a device.
Original Abstract Submitted
an indoor positioning method includes scanning for registered wi-fi nodes with known coordinates to generate a list of the registered wi-fi nodes. the method also includes performing a ranging operation by (i) selecting nodes to range with from the list of the registered wi-fi nodes, and (ii) processing ranging responses from the selected nodes to generate a series of distance measurements. the method further includes obtaining a series of sensor readings generated by one or more inertial measurement units (imus) of a device. the method also includes estimating a position of the device based on the series of distance measurements and the series of sensor readings using first and second filtering operations that are performed in parallel.
