Abstract

Described is an infant monitoring and alerting system capable of determining an absence of movement by an infant. When an absence of movement is detected the monitor attempts to stimulate movement using stimuli that may include a vibration, an audible alert, or a visual alert. If no movement is detected in response to the stimuli, the monitor may provide another instance of stimuli which may include stimuli at an elevated intensity or additional and/or different stimuli. The additional instance of stimuli may further attempt to stimulate movement by the infant and may also function as an alert to the caregiver that their attention may be required.

Claims

1. A monitoring device attachable to an infant, comprising:

an accelerometer configured to detect movement information of the infant;

at least one stimulus generating component configured to generate at least one type of stimulus, wherein the at least one type of stimulus comprises at least one of a vibration stimulus, an audible stimulus, or a visual stimulus; and

a controller configured to;

determine, based on the movement information, an absence of movement by the infant for a predetermined period of time;

initiate, in response to the determined absence of movement, at least one first stimulus by the at least one stimulus generating component to stimulate a responsive movement by the infant;

determine, based on additional detected movement information by the accelerometer following the at least one first stimulus, a continued absence of movement by the infant; and

in response to the determined continued absence of movement;

randomly select at least one second stimulus to prevent sensory adaptation, and

initiate the at least one second stimulus by the at least one stimulus generating component to further stimulate the responsive movement by the infant.

2. The monitoring device of claim 1, wherein the at least one second stimulus comprises a same type of stimulus as the at least one first stimulus, and the at least one second stimulus has a greater intensity of the same type of stimulus than the at least one first stimulus, wherein the at least one second stimulus includes a type of stimulus not included in the at least one first stimulus.

3. The monitoring device of claim 1, wherein the at least one second stimulus includes a type of stimulus not included in the at least one first stimulus.

4. The monitoring device of claim 1, wherein the controller is further configured to:

learn movement patterns of the infant; and

and adjust a length of the predetermined period of time based on the learned movement patterns of the infant.

5. The monitoring device of claim 1, wherein the controller is further configured to cease the at least one first stimulus or the at least one second stimulus upon detection of a movement by the infant.

6. The monitoring device of claim 1, wherein the movement information is associated with abdominal movements of the infant.

7. The monitoring device of claim 1, wherein the monitoring device is attachable to an article of clothing worn by the infant.

8. A method of monitoring an infant with a monitoring device attachable to an infant and comprising an accelerometer, at least one stimulus generating component, and a controller, the method comprising:

detecting, by the accelerometer, movement information of the infant;

determining, based on the detected movement information, an absence of movement by the infant for a predetermined period of time;

generating, by the at least one stimulus generating component and in response to the determined absence of movement, at least one first stimulus by the at least one stimulus generating component to stimulate a responsive movement by the infant;

determining, based on additional detected movement information by the accelerometer following the at least one first stimulus, a continued absence of movement by the infant; and

in response to the determined continued absence of movement;

randomly selecting at least one second stimulus to prevent sensory adaptation, and

generating, by the at least one stimulus generating component at least one second stimulus to further stimulate the responsive movement by the infant.

9. The method of claim 8, wherein the at least one second stimulus has a same type of stimulus as the at least one first stimulus, and the at least one second stimulus has a greater intensity of the same type of stimulus than the at least one first stimulus.

10. The method of claim 8, wherein the at least one second stimulus includes a type of stimulus not included in the at least one first stimulus.

11. The method of claim 8, wherein the at least one first stimulus includes the vibration stimulus and the at least one second stimulus includes the vibration stimulus and at least one of the audible stimulus and the visual stimulus.

12. The method of claim 8, further comprising ceasing the at least one first stimulus or the at least one second stimulus upon detection of a movement by the infant.

13. The method of claim 8, wherein the movement information is associated with abdominal movements of the infant.

14. The method of claim 8, wherein the monitoring device is attachable to an article of clothing worn by the infant.

15. A non-transitory computer-readable medium having instructions stored thereon that, in response to execution, cause a monitoring device attachable to an infant to perform operations comprising:

detecting movement information of the infant;

determining, based on the detected movement information, an absence of movement by the infant for a predetermined period of time;

generating, by at least stimulus generating component and in response to the determined absence of movement, at least one first stimulus by the at least one stimulus generating component to stimulate a responsive movement by the infant;

determining, based on additional detected movement information by the accelerometer following the at least one first stimulus, a continued absence of movement by the infant; and

in response to the determined continued absence of movement;

randomly selecting at least one second stimulus to prevent sensory adaptation, and

generating, by the at least one stimulus generating component at least one second stimulus to further stimulate the responsive movement by the infant.

16. The non-transitory computer-readable medium of claim 15, wherein the at least one second stimulus has a same type of stimulus as the at least one first stimulus, and the at least one second stimulus has a greater intensity of the same type of stimulus than the at least one first stimulus.

17. The non-transitory computer-readable medium of claim 15, wherein the at least one second stimulus includes a type of stimulus not included in the at least one first stimulus.

18. The non-transitory computer-readable medium of claim 15, wherein the at least one first stimulus includes the vibration stimulus and the at least one second stimulus includes the vibration stimulus and at least one of the audible stimulus and the visual stimulus.

19. The non-transitory computer-readable medium of claim 15, further comprising ceasing the at least one first stimulus or the at least one second stimulus upon detection of a movement by the infant.

20. The non-transitory computer-readable medium of claim 15, wherein the movement information is associated with abdominal movements of the infant.
