Abstract
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.
Claims20
A method comprising:
- emitting a sound by a first device;
- receiving a recorded sound at the first device, the recorded sound comprising a recording of the emitted sound by a second device;
- determining an intermediate frequency (IF) signal based on the emitted sound and the recorded sound;
- 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;
- and
- presenting the determined distance.
An electronic device comprising:
- at least one processing device configured to:
- control the electronic device to emit a sound;
- receive a recorded sound, the recorded sound comprising a recording of the emitted sound by a second device;
- determine an intermediate frequency (IF) signal based on the emitted sound and the recorded sound;
- and
- determine a distance between the electronic device and the second device based on a frequency of the IF signal and one or more characteristics of the emitted sound;
- and
- at least one display configured to show the determined distance.
A non-transitory machine-readable medium containing instructions that when executed cause at least one processor of an electronic device to:
- control the electronic device to emit a sound;
- receive a recorded sound, the recorded sound comprising a recording of the emitted sound by a second device;
- determine an intermediate frequency (IF) signal based on the emitted sound and the recorded sound;
- determine a distance between the electronic device and the second device based on a frequency of the IF signal and one or more characteristics of the emitted sound;
- and
- control at least one display to show the determined distance.
