Systems and methods relating to a millimeter wave radio-frequency (RF) sleep monitoring device are described. The device includes a surface transparent to RF signals through which a radar device enclosed in a housing transmits RF signals. An antenna array is enclosed within the housing and is oriented at a non-zero angle with respect to a vertical axis of the device. The antenna array receives the reflected RF signals through the surface. The reflected RF signals are used to generate sleep monitoring data such as a respiratory rate or motion data associated with a user.

Millimeter wave radar system for sleep monitoring

An audio device having a housing including a first loudspeaker disposed in the housing and oriented to emit sound towards a top of the housing, a second loudspeaker disposed in the housing and oriented to emit sound towards a bottom of the housing, and a third loudspeaker disposed in the housing and oriented to emit sound radially outward from the housing of the audio device. Embodiments may include a microphone array disposed proximate the top of the audio device and encircling the first loudspeaker.
