Abstract: Various arrangements are presented for issuing an alert based on a baby's behavior. A video stream that images a baby may be received. The video stream may be analyzed to determine the baby is in a non-auditory discomfort state. A notification may be determined to be output to a caregiver based on the determined non-auditory discomfort state. An alert may be output that is indicative of the non-auditory discomfort state to an end-user device.

Abstract: A method of monitoring physical characteristics of subjects in sleep environments may include receiving, through a video camera, a video feed of a subject in a sleep environment; analyzing the video feed of the subject to identify motion of the subject in the video feed; and causing a mobile device to present a representation of the motion of the subject, wherein the motion of the subject is exaggerated.

Abstract: Various systems, devices, and methods for contactless sleep tracking are presented. Based on data received from a contactless sensor, such as a radar sensor, determine that a user has entered a sleep state. A transition time may be determined at which the user transitions from the sleep state to an awake state. An environmental event, based on data received from an environmental sensor, may be identified as occurring within a time period of the transition time. The user waking may be attributed to the environmental event based on the environmental event occurring within the time period of the transition time. An indication of the attributed environmental event as a cause of the user waking may be output.

Abstract: Various arrangements are presented for measuring an amount of bilirubin in blood. A streaming video camera may capture a video feed of a portion of a room over a period of time. A background model may be created based on lighting conditions in the video feed. An amount of light absorption for blood present in skin of an infant may be determined using the background model. A bilirubin state for the infant may then be determined based on the amount of light absorption for the blood in the skin of the infant.

Abstract: Various arrangements for monitoring for contactless human interactions and health using a single radar transmission modulation mode are provided. Radar chirps may be output by a radar sensor operating in a burst mode. The burst mode radar data stream may be monitored for a contactless human interaction performed by an active user. The burst mode radar data stream may be converted to a virtual continuous mode radar data stream. Health monitoring of an inactive user may be performed using the virtual continuous mode radar data stream.

Abstract: A method of detecting and responding to a visitor to a smart home environment via an electronic greeting system of the smart home environment, including determining that a visitor is approaching an entryway of the smart home environment; initiating a facial recognition operation while the visitor is approaching the entryway; initiating an observation window in response to the determination that a visitor is approaching the entryway; obtaining context information from one or more sensors of the smart home environment during the observation window; and at the end of the time window, initiating a response to the detected approach of the visitor based on the context information and/or an outcome of the facial recognition operation.
