Classification: CPC A  G | IPC A  G

Claim 7:
8. A method comprising:
detecting, by a radar sensor of a monitoring device, a first set of radar signals associated with respiratory movements of at least one of a first user and a second user within a first zone comprising at least a portion of a bed;
generating a second zone adjacent to a first side of the bed, wherein the second zone corresponds to an angle diverging from the radar sensor of the monitoring device in a position when detecting the first set of radar signals;
detecting, by the radar sensor, a second set of radar signals associated with motion in the second zone;
detecting, by the radar sensor at a first time, a first subset of the second set of radar signals associated with first motion by the first user in the second zone;
detecting, by the radar sensor at a second time, a second subset of the second set of radar signals associated with second motion by the first user in the second zone; and
identifying a portion of the first set of radar signals corresponding to a time period between the first time and the second time;
generating a modified first set of radar signals by removing the portion of the first set of radar signals from the first set of radar signals; and
generating a sleep-related analytic associated with the first user using the modified first set of radar signals.
