Abstract: A method and system for detecting a fallen person is described. An initial range image corresponding to a field of view of a DAS is generated. Further, a reference plane disposed in the field of view is identified. Additionally, one or more regions in the initial range image indicative of one or more objects disposed above the reference plane in the field of view are determined. Further, the DAS regenerates a range image corresponding to the field of view after a determined time period. The regenerated range image is compared with the initial range image to determine if the regenerated range image comprises a new object disposed above the reference plane. The new object is determined to be the fallen person if a height of the new object is less than a determined height and a volume and/or a surface area of the new object is greater than a determined value.

Abstract: Methods and systems for monitoring a subject in a resting state using one or more range-controlled radars are presented. The radars non-invasively detect one or more motion and/or physiological parameters corresponding to the subject. The motion parameters comprise one or more activity levels and the physiological parameters comprise one or more of heartbeat and respiration. Further, one or more patterns in the motion parameters detected over a designated motion period of time are determined Additionally, one or more patterns in the physiological parameters detected over the designated physiological period of time are also determined The systems then assess a health condition of the subject based on the determined patterns of the motion parameters and/or the determined patterns of the physiological parameters.

Abstract: Methods, systems and non-transitory computer readable mediums that store instructions executable by one or more processors to perform a method for detecting a fallen person are presented. The present technique includes identifying a reference plane and a reference line in a designated space monitored using one or more range-controlled radars. These radars are coupled to one or more antennas configured to define fields of the range-controlled radars to one or more portions of the designated space, where at least one portion corresponds to the reference plane. The range-controlled radars detect presence of one or more parameters corresponding to a subject disposed in the designated space. The parameters, for example, include one or more physiological parameters and one or more motion parameters. The range-controlled radars then identify the subject as the fallen person if the one or more physiological parameters corresponding to the subject are detected proximate the reference plane.

Abstract: A method for detecting changes in locations of persons and objects is disclosed. The method includes projecting a plurality of imaging planes across a specified area near a ground level and at none or least one pre-determined height from the ground level. The method also includes capturing respective imaging lines from the plurality of planes via one or more imaging components, observed when the objects or persons intersect the projected imaging planes. The method further includes recording a standard shape of the respective imaging lines in absence of any person or object within the specified area to establish a baseline image. The method also includes comparing each of successive captured imaging lines with the baseline image of the respective lines. The method further includes determining one or more changes in discontinuities in the captured imaging lines due to interception caused by movement of the object based upon the comparison.

Abstract: A method and system for detecting motion is described. A data acquisition system is positioned at a desired position by establishing a reference line based on the desired position of the data acquisition system. Further, a field of view of the data acquisition system is partitioned into an upper region and a lower region based on the reference line. Subsequently, motion information corresponding to a person in the field of view is acquired. Additionally, it is determined if the acquired motion information corresponds to the upper region and/or the lower region in the field of view. Moreover, a magnitude of motion and an area of motion of the person are computed using the acquired motion information. Subsequently, a motion event corresponding to the person in the lower region of the field of view is detected based on the determined magnitude of motion and the determined area of motion.

Abstract: The present invention provides a computer implemented method for maintaining a knowledge base. The method taking as input, text examples that are tagged with a structural markup language; and maps knowledge nodes in the knowledge base with the tagged examples to determine: (1) the knowledge nodes that best match the tagged examples, and (2) the knowledge nodes that are best connected to the tagged examples. The results are displayed to the user, who verifies that the tagged examples match the selected knowledge nodes. Based on the user response, indices of the knowledge nodes are updated. The method may further include determining discrepancies between the existing knowledge base and the tagged examples, and further displaying the discrepancies to the user. The user can update the missing information in the knowledge base to remove the discrepancies in the existing knowledge base.

Abstract: A device and method for monitoring whether a resident is away from home or inactive within the home. A sensor, which includes a transmitter, a processor, a timer, and a detector, watches for motion to occur within a home. Upon sensing motion, the sensor sends a first signal indicative of the motion if the timer is not currently running and waits for the motion to end. If the timer already is running, the timer is restarted at zero. Upon expiration of a predetermined timing period, the sensor transmits a second signal indicative of inactivity. By comparing the timing of the second signal and the predetermined timing period, with a third signal sent by an exterior door sensor, a determination can be made whether the resident has left the home or is inactive within the home.

Abstract: A system and method for monitoring the activities of a resident living independently to distinguish normal activity from unusual activity. A variety of sensors distributed around the home collect data on activity in the home. The data is communicated to a remote monitoring center and collated in a database according to applicable time slots. The time slots for a twenty-four hour cycle are at least three and can be as many as forty-eight or more. Historical activity time lines are created and a buffer time is added to and offset from the maximum historical activity time line. If a new data point comes in that exceeds both the maximum historical activity time line and the buffer time, an alert is issued indicating the activity is unusual.
