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: 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: 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 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.
