Abstract: Techniques are provided for utilizing wireless devices for contact tracing, and more specifically for detecting a barrier between devices to enhance contact tracing applications. An example method for detecting a barrier between a first device and a second device includes determining, by the first device, a first range measurement with respect to the second device using a first positioning technique determining, by the first device, a second range measurement with respect to the second device using a second positioning technique that is different from the first positioning technique, and detecting the barrier between the first device and the second device based on the first range measurement and the second range measurement.

Abstract: Methods that may be performed by a processor of a computing device. Embodiments may include generating general inferences from personal data from the computing device in a manner that disassociates the general inferences from a user identity related to the personal data, coding the general inferences into a dynamic identifier (ID) configured to disassociate the dynamic ID from the user identity related to the personal data, and maintaining the dynamic ID at the computing device for use of the Dynamic ID at the computing device. Embodiments may include making the dynamic ID available for use at the computing device by an advertising software and/or an application developed by an independent software vendor configured to select advertisements at the computing device based on at least one of the general inferences of the dynamic ID.

Abstract: In some aspects, an electronic device may receive multiple inputs that each indicate current sensor information related to a liveness state associated with a human user. The electronic device may generate, based at least in part on the multiple inputs, liveness information that includes a liveness assessment word that represents the liveness state associated with each of the multiple inputs and a liveness indicator that indicates whether a human user is actively handling the electronic device. Numerous other aspects are described.

Abstract: Techniques are provided for enabling contextual Quality of Service (QoS) of mobile services. An example method of generating an output based on a contextual quality of service includes obtaining an input with a device module, determining a context indicator based on the input, determining a quality of service based at least in part on the context indicator, and generating the output based at least in part on the input and the quality of service.

Abstract: Disclosed are methods, systems, devices, servers, apparatus, computer-/processor-readable media, and other implementations, including a method that includes receiving by a device a triggering message from an emergency call server responsive to an indication of an emergency condition at the device to trigger a tracking session to periodically collect and send tracking session data associated with the device to one or more servers, establishing the tracking session, separate from an emergency call session established between the device and the emergency call server, with the one or more servers, and sending, by the device to the one or more servers, the tracking session data collected during the tracking session by the device.

Abstract: Disclosed are methods, systems, devices, servers, apparatus, computer-/processor-readable media, and other implementations, including a method that includes receiving by an emergency call server an indication of an emergency condition at a device, determining whether the device is to be tracked based, at least in part, on the indication of the emergency condition, and transmitting a triggering message from the emergency call server, in response to a determination that the device is to be tracked, to trigger at the device a tracking session to cause the device to periodically collect and send tracking session data to one or more servers. The tracking session, established between the device and the one or more servers, is separate from an emergency call session established between the device and the emergency call server.

Abstract: Disclosed are methods, systems and devices for addressing effects of transmission by a transmitter in an assigned uplink communication channel on a signal received at a receiver co-located with the transmitter. In a particular embodiment, communication in an alternative communication channel may be initiated in response to a determination that uplink transmission in the assigned communication channel likely interferes with at least one radio frequency receiving function.

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.
