Abstract: Various devices, systems and methods for performing targeted sleep tracking are presented herein. Multiple digital radar data streams from multiple antennas may be received. A direction optimization process may be performed to determine a first weighting and a second weighting. The first weighting may be applied to a first digital radar data stream. The second weighting may be applied to a second digital radar data stream. The weighted first digital radar data stream and the weighted second digital radar data stream may be combined to create a first directionally-targeted radar data stream. A sleep analysis can be performed based on the first directionally-targeted radar data stream. Sleep data may be output for a user based on the performed sleep analysis.

Abstract: Systems and techniques are provided for presence and directional motion detection. Signals may be received from a sensor positioned in a structure. An indication of directional motion may be generated based on the signals from the sensor. The indication of directional motion may be generated without using signals from additional sensors. A control signal for a device in the structure may be generated in response to the indication of directional motion. The control signal may be sent to the device in the structure to be implemented by the device.
