Classification: CPC A  G | IPC A  G

Claim 2:
3. The monitoring device of claim 1, wherein the operations further comprise:
determining a first value representing an orientation of a bore axis of the monitoring device in a first position, wherein the bore axis of the monitoring device in the first position is substantially perpendicular to the first side of the bed;
determining a second value representing the orientation of the bore axis of the monitoring device in a second position, wherein the bore axis of the monitoring device in the second position is substantially aligned with a location within the first zone corresponding to a respiratory zone of the first user when in a sleeping position;
determining a first angle diverging from the radar sensor of the monitoring device in the second position using the first value and the second value, wherein the first angle corresponds to an angular rotation of the monitoring device from the first position to the second position;
determining a second angle diverging from the radar sensor of the monitoring device in the second position using the first angle and a third value representing a perpendicular axis of the bore axis of the monitoring device in the first position, wherein the third value defines a first boundary axis of the second zone; and
determining a third angle diverging from the radar sensor of the monitoring device in the second position using the third value and a fourth value representing an offset angle from the perpendicular axis of the bore axis of the monitoring device in the first position, wherein the fourth value defines a second boundary axis of the second zone, wherein the second zone comprises a region between the first boundary axis and the second boundary axis.
