Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for reliable communication between a source device, and two or more sink devices. In one aspect, a sink device closest in proximity to the source device can establish a wireless data transfer with the source device. In another aspect, the sink device having the more favorable radio channel conditions can establish a wireless data transfer with the source device. In some aspects, the sink devices can forward audio data received from the source device over a secondary communication link. The audio data can be forwarded to the other sink device automatically, or upon request from the other sink device. The secondary communication link can be implemented as a magnetic communication link, or as a Bluetooth communication link.

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: Disclosed are systems, devices and methods for determining a range estimate between two Bluetooth enabled devices based, at least in part, on round trip phase measurements of wireless signals transmitted between the devices. In one example, phase estimates between a single antenna of a first device and each element within the antenna array of a second device may be used to determine a residual range between the first device and the second device. In addition, an Angle of Arrival (AoA) may also be used to determine a two dimensional or three dimensional position of the second device.

Abstract: Various embodiments include store picker systems that include a store management entity server, user mobile device(s), electronic shelf labels (ESL), and access points, in which the system perform methods for supporting in-store product picking. Some embodiment may include receiving/sending location information indicating a location in a store of a user mobile device operated by a store picker; receiving/sending a shopping list of the user mobile device, determining an initial route to travel through the store for picking one or more products on the shopping list based on the location, and sending/receiving the initial route to travel through the store for picking the one or more products on the shopping list to the user mobile device and from the store management entity server.

Abstract: According to various aspects and techniques to enable methods and systems for a first communication device to determine an approximate number of other communication devices that have lost contact with a host communication device. This includes determining a common future time window using a last known global time stamp and determining a transmit time within the common future time window. This also includes receiving samples that are captured during the common future time window on a predefined communication channel, as well as analyzing the received samples to estimate the total number of other communication devices.

Abstract: Secure range estimates as described herein may include determining a range estimate between two Bluetooth enabled devices based, at least in part, on round trip phase measurements of wireless signals transmitted between the devices. In one example, a range estimate may include determining a first set of relative carrier measurements at a first set of frequencies, determining a second set of relative carrier measurements based on the first set at the second set of frequencies; and combining the first set and the second set to estimate a distance between the devices.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive at least one signal from a second wireless device, the at least one signal including one or more of RTP information or inertial sensor information. The apparatus may determine at least one AoA measurement and at least one RTP measurement associated with the at least one signal received from the second wireless device. The apparatus may determine a path of trajectory of the second wireless device based at least in part on the at least one AoA measurement, the at least one RTP measurement, and the inertial sensor information.
