1. An apparatus for sleep monitoring, comprising:
a housing having an inner region and an exterior region enclosing the inner region;
a plurality of openings configured on the exterior region and that communicate with the inner region;
radio frequency (RF) components including an RF transmit antenna coupled to an RF generator and an RF receive antenna coupled to an RF receiver, the RF transmit antenna configured to emit RF signals and the receive antenna configured to receive backscattered RF signals derived from the emitted RF signals, the RF components being disposed within the inner region;
at least one processor within the inner region;
at least one non-transitory computer-readable medium within the inner region comprising instructions to cause the at least one processor to:
(i) determine a parameter associated with sleep of an individual based on the received backscattered RF signals; and
(ii) prescribe an action that, when carried out, modifies the parameter, resulting in an improvement of sleep of the individual; and
a natural convection spatial flow path flowing from the inner region and through at least one of the plurality of openings to the exterior region to draw heat from the at least one processor and the RF components without use of a fan, thereby avoiding fan-produced noise and vibration.
