Abstract: Methods and systems for user presence detection using wireless technology. A computer-implemented method includes receiving one or more data signals from at least one WiFi-node-to-Access-Point (AP) link or at least one WiFi-node-to-node link, performing a signal pre-processing process on the one or more data signals to generate one or more pre-processed data signals, performing the signal pre-processing process including performing a uniform sampling process, a power normalization process, an anomaly sample removal process, and a filtering process, extracting one or more features using the one or more pre-processed data signals, and using the one or more features to determine whether a user is present in the home and identify a specific room in which the user is located.

Abstract: An apparatus includes a microphone, a memory, and a processor operably coupled to the memory. The processor is configured to determine an energy level of an audio signal captured by the microphone and determine whether the audio signal indicates a possible fall. The processor is further configured to, upon a determination that the audio signal indicates the possible fall, poll a fall detection module.

Abstract: An electronic device includes a transceiver configured to transmit and receive ultrawide band (UWB) radar signals. The electronic device also includes a processor operatively coupled to the transceiver. The processor is configured to, based on the received UWB radar signals, detect a human within a detection area of the transceiver. The processor is further configured to perform, based on the detection of the human within the detection area of the transceiver, a motion detection operation, and perform, based on a result of the motion detection operation, a fall detection operation.

Abstract: A method includes obtaining personal activity data of a user generated by one or more sensing devices in proximity to the user. The method also includes receiving a user query from the user via a user interface. The method further includes using a large language model (LLM) based digital assistant to generate one or more user-specific suggestions or actions based on the personal activity data and the user query, the digital assistant comprising a hierarchical multi-LLM-agent structure that includes one or more pre-trained LLMs.

Abstract: Methods and apparatuses for negotiating a carrier-phase measurement interval in FTM protocol. A method of wireless communication performed by a first STA, the method comprising: negotiating, with a second STA, a duration of a time window for performing carrier-phase (CP) ranging; negotiating, with the second STA, a desired maximum speed of the first STA to be tracked; and negotiating, with the second STA, one or more inter-packet time parameters for use within the time window based on the desired maximum speed of the first STA to be tracked.

Abstract: Methods and apparatuses for operating multiple carriers in a wireless communication system. A method for a first network entity comprises: identifying a plurality of carrier frequencies for measuring carrier phases from a set of predefined carrier frequencies; estimating, based on the measured carrier phase, a distance between the first network entity and a second network entity using a carrier ranging operation that is performed between the first network entity and the second network entity; selecting, based on the estimated distance, historical information, a variation of measured distance, and channel status information, at least one carrier frequency from the plurality of carrier frequencies to refine distance measurement; and transmitting, to and receive from the second network entity, signals over the selected at least one carrier frequency.

Abstract: An electronic device includes a processor and a microphone. The microphone is configured to send audio, from an ambient environment of the electronic device, to the processor. The processor is configured to process, based on a current step size of an audio stream segmenter, the audio received from the microphone into an audio segment. The processor is further configured to determine whether the audio segment includes a snoring sound, and set a next step size of the audio stream segmenter based on the determination whether the audio segment includes the snoring sound.

Abstract: A method comprises receiving, by a radar sensor, reflections from at least two points on a body of a user. The method comprises determining, by a processor operatively coupled to the radar sensor, a change of an elevation angle and a rate of change of the elevation angle of the user with respect to the radar sensor, based on the reflections from the at least two points on the body of the user. The method comprises determining changes of a radar cross-section (RCS) associated with the body of the user along an elevation dimension. The method comprises determining whether a fall event occurred based on at least one of: the rate of change and the change of the elevation angle, or the changes of the RCS.

Abstract: A method includes obtaining range estimates and carrier phase estimates from each of multiple anchors. The method also includes, in response to determining that a trilateration technique is to be performed, (i) obtaining improved range estimates using the carrier phase estimates and (ii) determining a first location estimate of a target device using the trilateration technique and the improved range estimates. The method also includes, in response to determining that a triangulation technique is to be performed, (i) obtaining differential range estimates using the carrier phase estimates and (ii) determining a second location estimate of the target device using the triangulation technique and the differential range estimates. The method also includes combining the first location estimate and the second location estimate to determine an overall location estimate of the target device.
