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 methods, devices, systems, apparatus, servers, media, and other implementations, including a method, performed at a first wireless device, for secure range determination that includes transmitting a first signed message at a first time instance, with the first signed message, including a first payload, configured to be received by a second wireless device at a second time instance, and receiving at a fourth time instance a verifiable acknowledgement message transmitted from the second wireless device at a third time instance in response to the first signed message. The method further includes verifying that the verifiable acknowledgement message originated from the second wireless device, and, responsive to a verification that the verifiable acknowledgement message originated from the second wireless device, transmitting a second signed message including a second payload with at least timing information for the first time instance and the fourth time instance.

Abstract: Aspects may relate to a device to provide access to storage to authenticated actors only. The device may comprise a processor and a storage. The processor may be coupled to the storage and may be configured to: obtain a nonce; obtain an actor signed hash for an actor; and apply a key derivation function utilizing the actor signed hash and the nonce as inputs to create an actor specific key encapsulating key (KEK). The processor may command the storage of an actor specific storage key, wrapped using the actor specific KEK. Further, the processor may use the actor specific KEK to unwrap actor specific keys used to access storage.

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.

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.

Abstract: A method for handover of a set of wireless devices is described. The method includes receiving, at a first wireless device of the set of wireless devices, data from a first serving device of a set of serving devices. The first wireless device has a primary wireless device role and a second wireless device has a non-primary wireless device role. The method includes determining, at the first wireless device, a handover condition for the set of wireless devices. The set of wireless devices is handed over as a set to a second serving device. The method includes becoming detectable, by the first wireless device. Each of the wireless devices in the set of wireless devices is configured to become detectable in response to the handover condition. The method includes receiving, by the first wireless device, an indication of a selected wireless device of the set of wireless devices.

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.
