  • Methods and apparatus for detecting presence of an object in an environment
    Patent number: 10948581
    Abstract: Methods and apparatus for detecting presence of an object in an environment, the method including receiving a Doppler signal during a frame in frequency domain, separating the Doppler signal in the frequency domain into a plurality of sub-band signals, determining a plurality of sub-band signal energies corresponding to the plurality of sub-band signals, determining whether motion of the object is detected in accordance with one of the plurality of sub-band signal energies and a baseline energy, and responsive to a determination that motion of the object is detected, setting a flag of object presence.
    Type: Grant
    Filed: May 30, 2018
    Date of Patent: March 16, 2021
    Assignee: RICHWAVE TECHNOLOGY CORP.
    Inventor: Sheng Chung Kuo
  • Methods and apparatus for detecting presence of an object in an environment
    Patent number: 10928502
    Abstract: Methods and apparatus for detecting presence of an object in an environment, the method including receiving a Doppler signal during a frame, filtering the Doppler signal in a frequency band, determining a signal energy of the filtered Doppler signal in time domain, determining whether motion of the object is detected in accordance with the Doppler signal and a baseline energy, responsive to a determination that motion of the object is detected in accordance with the signal energy and the baseline energy, setting a flag of object presence, and responsive to a determination that motion of the object is not detected in accordance with the Doppler signal, updating the baseline energy in accordance with the signal energy.
