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: Techniques and systems are provided for performing one or more counter recognition techniques. For example, an incident signal can be received by a user device, and one or more signal parameters of the incident signal can be determined. Based on the one or more signal parameters of the incident signal, one or more response signals can be transmitted to prevent object recognition (e.g., face recognition) of a user by the camera.

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 is a mobile device to authenticate a user. The mobile device may comprise: a first sensor; a second sensor to use more power than the first sensor; and a processor coupled to the first sensor and the second sensor. The processor may be configured to: collect data from the first sensor; determine if an environmental change occurred based on the collected data from the first sensor; engage the second sensor to collect data if the environmental change occurred; and modify a polling rate for the second sensor based on the collected data from the second sensor.

Abstract: In an embodiment, a first media presentation session is established between a first Source and the Sink, and a second media presentation session between a second Source and the Sink. First and second media streams are streamed to the Sink by the first and second Sources, respectively. The Sink presents the first and second media streams in respective portions of a display screen, and detects user input at the Sink that is indicative of a trigger to transfer data originated from the first Source to the second Source. The Sink coordinates with one or both of the first Source and the second Source to facilitate the data to be delivered to the second Source in response to the detection. As a result of the coordination, the second Source receives the first Source-originated data (e.g., from the first Source directly, or via the Sink).
