SYSTEM AND METHOD FOR MEASURING PROXIMITY BETWEEN DEVICES USING ACOUSTICS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17931455 titled 'SYSTEM AND METHOD FOR MEASURING PROXIMITY BETWEEN DEVICES USING ACOUSTICS
Simplified Explanation
The patent application describes a method for determining the distance between two devices using sound signals. Here are the key points:
- The method involves emitting a sound from one device and recording it with another device.
- An intermediate frequency (IF) signal is determined based on the emitted and recorded sounds.
- The distance between the two devices is calculated using the frequency of the IF signal and characteristics of the emitted sound.
- The determined distance is presented to the user.
Potential Applications
This technology can have various applications, including:
- Indoor positioning systems: The method can be used to accurately determine the distance between devices in indoor environments, enabling applications such as indoor navigation or asset tracking.
- Proximity detection: The method can be used to detect the proximity of objects or devices, which can be useful in applications like smart homes or security systems.
- Augmented reality: By accurately determining the distance between devices, this technology can enhance augmented reality experiences by providing more precise spatial information.
Problems Solved
This technology addresses several problems:
- Distance measurement: The method provides a reliable and accurate way to measure the distance between two devices without the need for complex equipment or infrastructure.
- Non-invasive: The method uses sound signals, which are non-intrusive and can be easily implemented without requiring physical contact or additional sensors.
- Cost-effective: By utilizing existing devices and sound signals, this method offers a cost-effective solution for distance measurement compared to other technologies.
Benefits
The benefits of this technology include:
- Accurate distance measurement: The method provides a precise way to determine the distance between devices, enabling more accurate location-based services and applications.
- Easy implementation: The method can be implemented using standard devices with built-in microphones and speakers, making it accessible and easy to deploy.
- Cost-effective solution: By utilizing existing devices and sound signals, this technology offers a cost-effective alternative to other distance measurement technologies.
Original Abstract Submitted
A method includes emitting a sound by a first device. The method also includes receiving a recorded sound at the first device, where the recorded sound includes a recording of the emitted sound by a second device. The method further includes determining an intermediate frequency (IF) signal based on the emitted sound and the recorded sound. The method also includes determining a distance between the first device and the second device based on a frequency of the IF signal and one or more characteristics of the emitted sound. In addition, the method includes presenting the determined distance.
