Abstract

A system for wirelessly monitoring the health of an infant comprising a sensing module removably disposed within a wearable article. At least a portion of the sensing module can be in contact with an infant'"'"'s foot. The sensing module can include a processing unit configured to receive and process health readings received by the sensing module. A wireless transmitter can also be in communication with the processing unit. The wireless transmitter can be configured to transmit the processed health readings to a receiving station. The receiving station can indicate an alarm if the processed health readings indicate a health trend that falls outside of a particular threshold.

Claims

1. A system for wirelessly monitoring the health of an infant, the system comprising:

a sensing module removably disposed within a wearable article, wherein at least a portion of the sensing module is configured to be in contact with the infant'"'"'s foot;

the accelerometer also configured to determine a current sleeping position of the infant, wherein when determining the current sleeping position of the infant, readings from the accelerometer are allowed to settle and persist for a particular amount of time, and

a pulse oximeter configured to detect at least a blood-oxygen level of the infant; and

wherein the processing unit;

identifies a particular alarm level based upon a health reading relating to the blood-oxygen level of the infant that was acquired during time periods when the accelerometer did not detect movement of the infant'"'"'s foot,

elevates the particular alarm level to a higher alarm level based upon a reading received from the accelerometer that indicates the current sleeping position of the infant is face down, and

triggers an alarm alert at the higher alarm level.

2. The system as recited in claim 1, wherein the processing unit is configured to:

activate different combinations of photoreceptors and LEDs from a plurality of photoreceptors and LEDs within the pulse oximeter; and

identify a particular combination that provides the strongest relative signal.

3. The system as recited in claim 1, further comprising:

the pulse oximeter comprising a plurality of photoreceptors, wherein the processing unit is configured to activate each of the plurality of photoreceptors independently of each other and identify a particular photoreceptor of the plurality of photoreceptors that receives the strongest relative signal.

4. The system as recited in claim 1, further comprising:

the pulse oximeter comprising a plurality of LEDs, wherein the processing unit is configured to activate each of the plurality of LEDs independently of each other and identify a particular LED of the plurality of LEDs that generates a strongest relative signal as received by a particular photoreceptor.

5. The system as recited in claim 1, wherein the processing unit is configured to analyze raw pulse oximetry data and compress the data before the data is transmitted to a receiving station.

6. The system as recited in claim 1, wherein a receiving station is configured to indicate an alarm when the processed health readings indicate a health trend that falls outside of a particular threshold.

7. The system as recited in claim 6, wherein the processing unit is configured to disregard abnormal health readings that were detected during the same time period that the accelerometer detected movement.

8. The system as recited in claim 6, further comprising:

a camera that is in communication with the receiving station, wherein the camera is configured to transmit an image when the processed health readings indicate a health trend that falls outside a particular threshold.

9. The system as recited in claim 8, wherein the camera transmits an image to a mobile phone.

10. The system as recited in claim 6, wherein the receiving station comprises software that processes received health readings from the wireless transmitter.

12. The system as recited in claim 1, further comprising:

the sensing module comprising a vibrator that is configured to activate in response to abnormal health readings.
