    Abstract: A sonic ranging method for a mobile phone and a wireless earphone. Firstly, the mobile phone performs an acoustic response test on the wireless earphone. The mobile phone generates a first audio sequence at a first time slot. The wireless earphone recognizes the first audio sequence to generate a second audio sequence. When the mobile phone recognizes the second audio sequence, the mobile phone estimates a length of elapsed time according to the time difference between a current time slot and the first time slot. When the mobile phone obtains the length of elapsed time, a distance between the wireless earphone and the mobile phone may be determined according to a delay compensation parameter and the length of elapsed time. Various potential applications can be implemented based on the invention without the needs for additional hardware circuits in the mobile phone.

    Abstract: A playback device is configured to (i) detect, while a graphical display is in a sleep state, that a user is proximate to the playback device, (ii) cause the graphical display to exit the sleep state and present a GUI including a list of selectable quick start icons, each quick start icon corresponding to a respective command to begin playback of respective media content, where the list does not include information identifying the respective media content, (iii) determine that a predetermined period of time has passed after causing the graphical display to exit the sleep state, (iv) update the graphical display to include information identifying the respective media content corresponding to each quick start icon, (v) detect an input selecting one of the quick start icons via the graphical display, and (vi) based on the input, begin to play back the media content corresponding to the selected quick start icon.

    Abstract: A receiving apparatus (7) that can estimate a motion-induced frequency shift in a received signal comprises a processing system (205) and a receiver (204) configured to receive a signal comprising one or more instances of a transmitted signal. The processing system (205) is configured to generate data representative of a plurality of impulse response functions by deconvolving the received signal with each of a plurality of templates representative of the transmitted signal shifted in frequency by a different respective frequency shift. The processing system (205) is further configured to evaluate a signal-to-noise measure for each of the plurality of impulse response functions, and to identify an impulse response function of the plurality of impulse response functions for which the signal-to-noise measure satisfies a peak criterion.

    Abstract: Systems and methods of estimating a location of a mobile computing device are provided. For instance, acoustic signals can be received from one or more transmitting devices associated with a real-time locating system. A set of peaks can be selected from the received acoustic signals. A first set of transmitter locations can be assigned to the selected set of peaks. The first set of transmitter locations can be specified by an acoustic model specifying a plurality of transmitter locations within an acoustic environment in which the one or more transmitting devices are located. A first model path trace associated with the first set of transmitter locations can be compared to the received acoustic signals. A location of the mobile computing device can be estimated based at least in part on the comparison.

    Abstract: A method of determining a distance between a vehicle and a sound source includes detecting, at a microphone of the vehicle, sounds from a sound source external to the vehicle. The sounds have a first frequency component at a first frequency and a second frequency component at a second frequency. The method also includes determining, at a processor of the vehicle, a classification of the sound source based on audio properties of the sounds. The method further includes determining a first energy level associated with the first frequency component and a second energy level associated with the second frequency component. The method also includes determining a ratio between the first energy level and the second energy level. The method further includes determining the distance between the vehicle and the sound source based on the ratio and the classification of the sound source.

    Abstract: Disclosed is an electronic device that includes a display, a communication module, at least one microphone, at least one speaker, a processor operatively coupled to the display, the communication module, the microphone, and the speaker, and a memory operatively coupled to the processor. The memory may store instructions, when executed, causing the processor to transmit, through the speaker, a first audio sound including first information, receive, through the microphone, a second audio sound including second information responding to the first information from a first external electronic device, transmit, through the speaker, a third audio sound including third information for acquiring a distance to the first external electronic device after receiving the second audio sound, and receive, through the microphone, a fourth audio sound including fourth information responding to the third information from the first external electronic device.
