Samsung patents UWB radar to detect falls in electronic devices

Samsung has been granted a patent for a system that uses ultrawideband (UWB) radar signals to monitor movement. The device processes these signals to identify a person in a specific area and analyzes their motion patterns to determine if they have fallen.

Why it mattersThis technology could allow phones or other gadgets to automatically detect falls without needing a camera, offering a privacy-friendly safety feature for elderly users or those with mobility issues.

In the filing’s own words

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.

What exactly they claim (claim 1)

1. An electronic device comprising: a transceiver configured to transmit and receive ultrawide band (UWB) radar signals; and a processor operatively coupled to the transceiver, the processor configured to: generate a plurality of UWB channel impulse response (CIR) frames based on the transmitted and received UWB radar signals; store the plurality of UWB CIR frames within a buffer; preprocess the plurality of UWB CIR frames stored within the buffer; perform range doppler calculations on the preprocessed plurality of UWB CIR frames; perform, based on a result of the range doppler calculations, a range bin selection operation; detect a human within a detection area of the transceiver based on a result of the range bin selection operation and based on removing one or more non-human artifacts; 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.
