  • Patent number: 11906540
    Abstract: Various approaches for automated fall detection, implemented in wearables and other device form factors of a personal emergency response system (PERS) are disclosed. In an example, a hybrid approach for fall detection includes: identifying a potential fall event from three-dimensional motion data of a human subject, using filtering rules; evaluating the motion data with a machine learning model (e.g., a decision tree ensemble (DTE) model), to produce a first determination that a fall has occurred; evaluating the motion data with a deep learning neural network (e.g., recurrent neural network such as a gated recurrent unit (GRU)), to produce a second determination that a fall has occurred; classifying the potential fall event as a fall condition for the human subject, based on the first determination and the second determination; and outputting data to indicate the fall condition for the human subject.

  • Publication number: 20210236021
    Abstract: Lower extremity motion data may be received from one or more sensors. The lower extremity motion data may be used to quantify propulsion performance, which is used to calculate one or more gait characteristics of the lower extremity. A risk level of the lower extremity may be determined based, at least in part, on the calculated gait characteristics.

  • Patent number: 10856810
    Abstract: Systems and methods for using a smart carpet to monitor a health status of an individual. The smart carpet has electronics and a plurality of pressure sensing areas for sensing plantar pressure of the individual. A monitoring computer comprising a processor and a memory including machine readable instructions processes carpet data. A first part of the smart carpet is scanned at a first frequency and a second part of the smart carpet is scanned at a second frequency greater than the first frequency. Plantar pressures are received from the second part of the carpet and the instructions evaluate the plantar pressures to determine at least one of a physical activity and a physiological activity. Where an emergency condition is determined, an alarm is communicated to monitoring personnel.
