Patent number: 11363396Abstract: The present disclosure provides an audio playback system adapted to automatically switch an active microphone back and forth between two or more devices. For example, where the system is a pair of earbuds, where each earbud is worn by a separate user, the system may switch the active microphone to the device worn by the user that is speaking at a given time. While that device holds the active microphone, the other device may wait until a particular event that frees up the microphone, such as if the user wearing the device with the active microphone stops talking. According to some examples, a notification may be provided through one or more of the devices in the system to let the user know, for example, that he does not have the active microphone, that the active microphone is free, that the active microphone has been switched, etc.Type: GrantFiled: February 24, 2021Date of Patent: June 14, 2022Assignee: Google LLCInventor: Vitali Lovich

Patent number: 11191024Abstract: The present disclosure provides for power conservation in truly wireless earbuds or other paired wireless devices, by switching a secondary device into a power save mode when the devices are not receiving traffic from the host. In this power-save mode the devices are put into a lower duty cycle than conventional configuration. The primary and secondary devices communicate over a backchannel communication link at a very low duty cycle, in some examples below lower bounds specified for standard communication with other devices. The primary earbud may be responsible for letting the secondary earbud know when to leave power-save mode and resume regular operation.Type: GrantFiled: January 9, 2019Date of Patent: November 30, 2021Assignee: Google LLCInventor: Vitali Lovich

Patent number: 11134331Abstract: An audio playback system may be adaptable to various situations for improved user experience and audio playback quality. For example, earbuds may be both worn by a same user, worn by two different users within audio range of one another, worn by two different users outside of audio range of one another, etc. A second earbud with a secondary microphone operates in a second mode in which it captures audio and encodes it for transmission to the first earbud having a primary microphone. The first earbud with the primary microphone operates in a first mode in which it mixes the audio received from the second earbud with audio received through its own microphone for playback. The first earbud in the first mode may also delay its own microphone stream to compensate for wireless transmission delay and correlate the two audio streams to improve audio quality in case there are sounds that can be picked up by both microphones.Type: GrantFiled: November 14, 2019Date of Patent: September 28, 2021Assignee: Google LLCInventors: Vitali Lovich, Jeffrey Kuramoto

Patent number: 10681666Abstract: Coarse location estimation for mobile devices is disclosed for detecting mobile device presence at general locations of interest and switching operating modes and services for one or more location context aware applications. In some implementations, sensor data is received from a plurality of data sources at a location. For each data source, a first probability is estimated that the mobile device is at the location based on sensor data from the data sources. A second probability is estimated that the mobile device is not at the location based on sensor data from the data sources. The first and second estimated probabilities are statistically combined to generate a third estimated probability that the mobile device is at the location.Type: GrantFiled: September 5, 2014Date of Patent: June 9, 2020Assignee: Apple Inc.Inventors: Brian Stephen Smith, Joseph Ding-Jiu Huang, Ilya K.

Patent number: 9838848Abstract: Methods, systems, and computer program product for prefetching location data based on predicted user behavior. A mobile device can request, from a user routine subsystem of the mobile device, a list of locations that a user of the mobile device routinely visits while the user carries the mobile device. The mobile device can determine a cluster of these locations that are within a specified distance between one another. The mobile device can request location data for these locations from a location server, even if the user is not at one of these locations. The location data can include a venue map and a venue location fingerprint. Upon detecting that the user entered a venue at one of these locations, the mobile device can determine a location of the user inside of the venue using the venue location fingerprint. The mobile device can then display the location on a venue map.Type: GrantFiled: September 25, 2015Date of Patent: December 5, 2017Assignee: Apple Inc.Inventors: Vitali Lovich, Darin Tay, Robert Mayor, Joseph Ding-Jiu Huang

Patent number: 9769622Abstract: Methods, systems, and computer program product for generating location fingerprint data for a venue are described. A sampling device surveying a venue can move inside the venue. While the sampling device moves, the sampling device can record environmental readings including, for example, strengths of signals from multiple radio signal sources. The sampling device can take the recording at fixed or various time intervals. Meanwhile, the sampling device can determine, based on a starting point and motion sensor readings, an estimated location of the mobile device for each time the sampling device takes the recordings. The sampling device can display a motion path of the estimated locations and a user interface item for receiving a user input for correcting the estimated locations. The sample device can tag the recorded environmental readings with the corrected locations, and submit the tagged readings to a server for determining a location fingerprint for the venue.Type: GrantFiled: September 30, 2014Date of Patent: September 19, 2017Assignee: Apple Inc.Inventors: Abhinav R.

Patent number: 9638784Abstract: Methods, systems, and computer program product for deduplicating location fingerprint data for a venue are described. A system including a location server, or a mobile device, or both, can deduplicate the location fingerprint data. Deduplicating the location fingerprint data can include identifying correlated signal sources the signals of which are mutually dependent such that measurements of one signal source can be used to predict measurements of another. The system can determine a mutual information entropy value for each pair of signal sources, and identify the correlated signal sources based on high mutual information entropy value. The system can adjust weights of the correlated signal sources in location determination.Type: GrantFiled: September 29, 2015Date of Patent: May 2, 2017Assignee: Apple Inc.Inventors: Abhinav R.

Patent number: 9491585Abstract: Methods, systems, and computer program product for location determination using dual statistical filters are described. A mobile device can determine a location of the mobile device using a particle filter and a Kalman filter. The particle filter can filter candidate locations of the mobile device using measurements of environment variables in the venue. The Kalman filter can filter inputs from a sensor of the mobile device for measuring angular movement of the mobile device. The particle filter and the Kalman filter can be linked by heading of the mobile device. Output of the Kalman filter can be used to determine where to place particles, or candidate locations, in a next iteration of the particle filter. Output from the particle filter can be used to determine a center mode of the Kalman filter and to determine a bias of the sensor for measuring angular movement.Type: GrantFiled: May 31, 2014Date of Patent: November 8, 2016Assignee: Apple Inc.Inventors: Joseph Ding-Jiu Huang, Abhinav R.

Patent number: 9451448Abstract: Apparatus and methods for changing one or more functional or operational aspects of a wireless device, such as upon the occurrence of a certain event. In one embodiment, the event comprises detecting that the wireless device is within range of one or more other devices. In another variant, the event comprises the wireless device associating with a certain access point. In this manner, various aspects of device functionality may be enabled or restricted (device “policies”). This policy enforcement capability is useful for a variety of reasons, including for example to disable noise and/or light emanating from wireless devices (such as at a movie theater), for preventing wireless devices from communicating with other wireless devices (such as in academic settings), and for forcing certain electronic devices to enter “sleep mode” when entering a sensitive area.Type: GrantFiled: August 3, 2015Date of Patent: September 20, 2016Assignee: Apple Inc.Inventors: Vitali Lovich, Michael Bell
