Abstract: Disclosed are methods, systems, devices, apparatus, computer-/processor-readable media, and other implementations, including a method that includes obtaining, at a mobile device, remote transmitter location estimates for one or more remote transmitters, obtaining, at the mobile device, a group of pedestrian dead-reckoning (PDR) measurements, obtaining, at the mobile device, a group of signal measurements for signals received from the one or more remote transmitters, and deriving at least one mobile device location estimate for the mobile device based on one or more inconsistency terms representative of inconsistency between different location solutions, for the at least one mobile device location estimate, computed using different data points from the remote transmitter location estimates for the one or more remote transmitters, the group of PDR measurements, and the group of signal measurements.

Abstract: Disclosed are systems, devices and methods for determining a range between devices based, at least in part, on measurements of wireless tone signals transmitted between devices. In particular, two devices may measure tone signals transmitted between the two devices for determination of a round-trip phase measurement. Obtaining multiple round-trip measurements from tone signals transmitted at different carrier frequencies may enable resolving at least some range ambiguities.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support guidance of users to particular locations within a facility. In a first aspect, RF fingerprints are determined at locations within the facility based on signal strengths from RF devices, including electronic shelf labels (ESLs). A graph may be determined based on the RF fingerprints. A current location for a user may be determined based on a current RF fingerprint for the user. A route through the graph may be determined through the facility and may be displayed to the user as the user navigates the facility. Other aspects and features are also claimed and described.

Abstract: A location device (e.g., realized at one or more of a mobile device and/or a location server) includes a wireless transceiver, one or more location sensors and a floor-plan of a venue. The location device determines a plurality of hypothetical locations of a mobile device in the venue in response to data sets provided by the one or more location sensors. The data sets are associated with obstacle indication values calculated for the venue or for regions of the venue including locations corresponding to the data sets. The obstacle indication values indicate the proximity or orientation of the obstacle edges in the region or in the venue. The location device refines the one or more hypothetical locations based on the obstacle indication values to provide an estimate of the current location of the mobile device.

Abstract: This disclosure provides systems, methods, and devices for Electronic Shelf Label (ESL) systems that support positioning of ESL devices. In a first aspect, a method includes: transmitting, to each ESL device in a group of ESL devices deployed within an environment via a wireless network associated with the environment, a command to emit one or more flashes of light over a flash interval associated with the group; receiving, from a mobile device via the wireless network, visual data collected for the group by a camera during the flash interval; detecting, within the visual data, the one or more flashes emitted by each ESL device in the group over the flash interval; and determining a location within the environment of each ESL device in the group based on the one or more flashes emitted by each ESL device in the visual data. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure generally relate to magnetometer calibration. In some aspects, a device may obtain multiple sets of magnetic field measurements corresponding to multiple local magnetic field strengths, wherein each set of magnetic field measurements is measured in association with an unknown local magnetic field strength. The device may calculate multiple error values using the multiple sets of magnetic field measurements, estimated values of the multiple local magnetic field strengths, and estimated hard iron bias values. The device may identify a set of hard iron bias values for magnetometer calibration based at least in part on comparing the multiple error values. The device may calibrate a magnetometer using the identified set of hard iron bias values.

Abstract: Various embodiments provide systems and methods which disclose a device which may be used to determine an audio event based on receiving an audio signal. Based on the determined audio event, audio activity may be tracked. The tracked audio activity may be summarized based on a summary mode. Feedback of the summarized tracked audio activity may be based on a feedback mode.
