Abstract: Various embodiments may provide systems and methods for determining a distance to a short in a two-conductor wire. Various embodiments may include determining a distance to a short in a two-conductor wire based at least in part on a phase difference between a phase of an injected tone and a phase of a reflected tone. Various embodiments may include determining a distance to a short in a two-conductor wire based at least in part on both a phase difference and an amplitude difference between an injected tone and a reflected tone. Various embodiments may include determining a distance to a short in a two-conductor wire based at least in part on a measured peak voltage of a combined pulse.

Abstract: This disclosure provides systems, methods, and devices that support converting position information from a device to positional descriptions with respect to descriptional layouts of assets at a location. In a first aspect, a method of wireless communication includes obtaining position information associated with a user equipment (UE) and retrieving one or more frames of a survey video of a location that correspond to an estimated position of the UE. The estimated position is based on the position information. The method includes extracting a set of features from the one or more frames and outputting a description of the estimated position with respect to a descriptional layout of assets at the location based on one or more descriptions identified from the descriptional layout. The one or more descriptions are identified based on the set of features. Other aspects and features are also claimed and described.

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: 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: 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: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for identifying, by a wearable device, a baseline antenna impedance value, detecting one or more sensor inputs, monitoring for a variation in antenna impedance from the baseline antenna impedance value, identifying a user gesture (e.g., based at least in part on the detected sensor inputs and the variation from the baseline antenna impedance value) at least one user gesture, and updating an operational status of the device based on the detected user gesture.
