  • Client device 32 typically comprises a smart phone, tablet or personal computer, which enables a caregiver 34 in another room of residence 28 to monitor infant 26, even when there is no Internet connection available.
  • Server 38 makes video images available to authorized remote client devices 44, thus enabling a caregiver 46 to monitor infant 26 at any location where there is access to public network 36.
  • the Wi-Fi or other local network connection provides reliable video streaming from camera head 22 to client device 32 with high bandwidth and low latency, even if the external Internet connection is not working.

  • Fig. 2B is a top view.
  • monitoring camera head 22 stands against a wall over crib 24.
  • the wall-standing configuration is recommended when the crib is placed against the wall for two reasons: The user can push the crib all the way against the wall; and two bumpers on the vertical part of the mount (shown in Fig. 9) add extra friction that make it harder for a child to rock the mount from side to side. In both the wall-standing and free-standing configurations, the mount cannot fall into the crib, and at worst will fall on the floor outside the crib.
  • the mount can be fixed to the wall for additional security.
  • Camera head 22 is held at the end of an arm at the upper end of a tripod mount (shown in greater detail in Figs. 7 and 8A/B).
  • the arm is designed so that: 1) Caregiver 34 can place infant 26 in crib 24 without coming across or bumping the arm; 2) Caregiver 34 can easily reach camera head 22 to detach it from and attach it to the mount when desired; and 3) A two-year-old child will not be able to reach the mount at the point where it starts bending and thus will not be able to hang from the arm.
  • Camera head 22 is placed behind crib 24, at the midpoint of the long side of the crib.
  • the natural curve of the freestanding mount achieves the optimal starting point angle (with elevation of approximately 20° above the horizontal) for the camera head.
  • the camera head has rotation and elevation articulation directions, as illustrated in the figures that follow.
  • Camera head 22 is positioned and adjusted so that the camera head has a field of view 50 from a fixed perspective that encompasses the area of crib 24, along with an intervention region 52 adjacent to the crib.
  • This perspective provides server 38 with image information that can be analyzed conveniently and reliably to detect both motions of infant 26 and actions taken by caregiver 34 in relation to the infant.
  • Adjustment of the camera mount (as described further hereinbelow) enables the camera head angle to be changed as necessary to accommodate different mounting locations.
  • caregiver 34 After assembling and setting up camera head 22 in this manner, caregiver 34 performs a simple calibration procedure: The caregiver views the video stream output by the camera head, for example on device 32 using an application dedicated to the camera, as described hereinbelow.
  • the desired crib boundaries are overlaid as a graphical element on the image, at an offset from the center of the image chosen so that the image will also include intervention region 52.
  • the caregiver adjusts the camera head until the actual crib boundaries match the desired boundaries shown in the overlay, and then locks the camera position. With camera head 22 locked in position, caregiver 34 clicks an "OK" control on device 32, and the camera captures an initial reference image. Subsequently, when the camera is in actual use, the captured images are registered and compared to this initial reference image in order to detect changes in the field of view. This registered image can then become the new reference image.

  • a monitoring camera head 62 (similar or identical in design to camera head 22 mentioned above) is held in place by a base 64, which is mounted directly on the wall, for example by a screw-in bracket.
  • Camera head 62 is attached to base 64 by an arm 66.
  • Camera head 62 can be attached to various other types of mounts, as well, such as freestanding mounts (shown in the figures that follow) and mounts that attach to the crib or the ceiling.
  • the plug on each mount has a distinguishing feature, such as a protruding pin of a different size, which fits into a receptacle on the camera head and enables the camera head to distinguish between different mounts. This information is useful in checking and updating the assumptions used in computerized analysis of the images output by the camera head.
  • An angle adjustment dial 70 enables the user to adjust the rotation and elevation angles of camera head 62.
  • dial 70 must to be pushed in order to change the orientation of the camera head. Consequently, when the dial is released, the viewing angle is locked, thus preventing the camera head from being moved up or down unintentionally.
  • friction-based mechanisms may be used to lock the viewing angle. As noted earlier, it is helpful to keep the camera head in a fixed position to ensure that the computer vision algorithms applied by server 38 to the images of infant 26 will run accurately.

  • a diffuser can be used to spread the infrared light uniformly across the crib. The diffuser is also useful in 1) reducing the red-glow effect of the IR LEDs when looking at the camera head from below; and 2) minimizing the risk of IR radiation to the child's retina.
  • Camera head 62 comprises an infrared- sensitive image sensor 74, which may conveniently have a standard 4:3 aspect ratio to fit the size of a standard crib 24 with the addition of intervention region 52 alongside the crib.
  • the resolution and sensitivity of sensor 74 are optimized for night conditions.
  • the top part of camera head 62 comprises a night light 82, which emits visible illumination.
  • This part of case 72 is made of a semi-transparent plastic, and contains a reflector with an LED inside to support the night light effect.
  • Night light 82 is directed toward the ceiling so that the infant at any location inside crib 24 will not see a direct light. The illumination is strong enough to enable caregiver 34 to see what is happening in the crib, but low enough to avoid waking the child. Night light 82 can be gradually dimmed on and off so that there will not be a drastic change in lighting that could wake the infant.
  • the lighting level can be controlled by pulse-width modulation, at frequencies high enough to prevent the stimulation of an epileptic seizure in a child who may be susceptible.
  • Camera head 62 transmits streaming video signals over a wireless LAN (Wi-Fi) connection, using a directional antenna 86: Because the camera head is located in a known, fixed position above crib 24, the antenna is designed to minimize emission of radiation in the downward direction. Wi-Fi pairing can be performed using a Bluetooth® low-energy (BLE) link, without the need for a QR code. Pairing takes place automatically or can be invoked by pressing a Wi-Fi button 80 on camera head 62.
  • Wi-Fi wireless LAN
  • Camera head 62 optionally includes additional sensors and/or output devices, such as a microphone 88 and an audio speaker 90, as well as temperature and humidity sensors 92. These latter sensors can be mounted externally to case 72 (rather than inside the shell) in order to provide more accurate readings.
  • One or more status LEDs 94 are located in a position that is easily visible to caregiver 34, such as at the front-top side of camera head 62.
  • camera head 62 may comprise one white LED with several states, such as No light, Blinking light, and Light on.
  • night light 82 can perform these signaling functions. When all is well, the light will initially be on and will then slowly (over the course of a few minutes) be turned down to avoid any unnecessary light in the room.

  • Video segments with identified changes in pixels in section (O) along a series of consecutive frames are classified as Visit. Segments between Awake - Awake, Visit - Awake, and Awake - Visit are classified as Asleep, while other segments are classified as Away, meaning that the infant is not in the crib.
  • the Visit state can be divided into sub-states depending on the nature of the caregiver interaction, for example: check-in, taking care, and removing the infant from of or placing the infant in the crib.
  • server analyzes movement occurring both in the crib and in the intervention region. If the infant is in the crib and movement is detected outside the crib, the visit sub-state is classified as "check-in.” If the infant is in the crib and movement occurs both outside and inside the crib, the visit sub-state is classified as "taking care.” If the infant is in the crib, movement is detected outside of the crib, and then subsequently there is no infant in the crib, then the visit sub-state is "removal of infant,” and vice versa for "placement of infant” in the crib.
  • Table I below presents example events, based on changes in the states of the images analyzed by server 38, along with the messages to the caregiver that are generated in response to each event. As noted earlier, these events relate to the behavior of both the infant and caregivers, and thus can assist caregivers in modifying their own behavior in a way that will encourage good sleep habits by the infant.
  • Status message 146 typically lists the most recent event, along with the time elapsed since its occurrence, while event message 148 lists events that occurred in the course of the night.
  • Section 152 includes a time plot 154, which displays caregiver presence in the scene of the crib and correlates it with infant sleep and wake periods, temperature and humidity. The plot also displays periods in which the infant was not in the crib. Specifically, plot 154 is made up of bars 156 showing periods during which the infant was asleep in the crib, bars 158 indicating the periods during which the infant was out of the crib, bars 160 indicating caregiver visits, and bars 162 indicating periods during which the infant was awake in the crib. Plot 154 thus enables caregivers to visualize the entire pattern of their interactions with the infant and its effect on infant sleep and waking periods. Section 152 also provides other summary information, including a plot 164 of temperature (as measured by sensor 92) and sleep and waking time data 166 computed by server 38.

  • the night summary can use sleep analytics to generate a sleep quality score, based on criteria such as time to sleep onset, total time asleep, sleep efficiency (total time asleep divided by total time in bed), and number and duration of visits by caregivers. Furthermore, server 38 can distinguish between and report different type of visits, such as check-in, taking care, and taking the baby out of or into the crib.
  • the day summary is an aggregation of naps that occurred in the period of the day and typically includes the total time asleep and the last time asleep and wakeup time (which help to plan the next nap), as well as details such as the number of naps and total time in bed.
  • the night and the day summaries are separated by the "night_start" and "night_end” points of each day.
  • the night_start is typically set to be the last time the infant is put in the crib before the night's sleep and after 6 PM. (This time is a default, which caregivers can modify, taking into account the normal day routine in Western countries.)
  • the night_end is the first time the infant is taken out of the crib after the night sleep and before 9 AM (again, a default that can be modified).
