Patent ID: 8742935

Claim:
A method for detecting a fallen person, comprising: identifying a reference plane and a reference line in a designated space; monitoring the designated space using one or more range-controlled radars coupled to one or more antennas are configured to define corresponding fields of the one or more range-controlled radars to one or more portions of the designated space, wherein at least one of the one or more portions corresponds to the reference plane; detecting presence of one or more parameters corresponding to a subject disposed in the designated space using the one or more range-controlled radars, wherein the one or more parameters comprise one or more physiological parameters and one or more motion parameters; identifying the subject as the fallen person if the one or more physiological parameters corresponding to the subject are detected proximate the reference plane; continually monitoring the one or more physiological parameters corresponding to the fallen person; generating an audio output, a visual output, an alert message, or combinations thereof, upon determining a reduction in values of the one or more parameters corresponding to the fallen person below corresponding threshold values; and terminating the audio output, the visual output, the alert message, or combinations thereof, upon determining a change in the values of the one or more parameters corresponding to the fallen person such that the changed values fall within the corresponding threshold values.
