Abstract

Apparatus and methods are described including apparatus for monitoring a female subject that includes a sensor, configured to monitor the subject without requiring compliance of the subject, and to generate a sensor signal in response to the monitoring. A computer processor is configured to receive the sensor signal, analyze the sensor signal, in response to the analyzing, identify whether the subject is in a pregnant state or a non-pregnant state, and generate an output in response thereto. Other applications are also described.

Claims

1. Apparatus for monitoring a female subject, the apparatus comprising:

a sensor, configured;

to be disposed at a location selected from the group consisting of;

upon the subject'"'"'s bed, and within the subject'"'"'s bed,

to monitor the subject, while the subject is in her bed, without requiring compliance of the subject, and

to generate a sensor signal in response to the monitoring, the sensor signal being indicative of the subject'"'"'s own heartbeat; and

a computer processor, configured to;

receive the sensor signal,

analyze the sensor signal, by comparing the subject'"'"'s own heartbeat to a heartbeat previously exhibited by the subject,

based upon comparing the subject'"'"'s own heartbeat to the heartbeat previously exhibited by the subject, identify whether the subject is in a pregnant state or a non-pregnant state, and

generate an output in response thereto.

2. The apparatus according to claim 1, wherein the computer processor is configured to identify whether the subject is in the pregnant state or the non-pregnant state without determining a temperature of the subject.

3. The apparatus according to claim 1, wherein the computer processor is configured to identify whether the subject is in the pregnant state or the non-pregnant state, using a machine-learning algorithm.

4. The apparatus according to claim 1, wherein the subject'"'"'s bed includes a mattress, and wherein the sensor is configured to be disposed within the subject'"'"'s bed, underneath the mattress of the subject'"'"'s bed.

5. The apparatus according to claim 1, wherein the computer processor is configured to analyze the sensor signal, by comparing the subject'"'"'s own heartbeat to a heartbeat that was previously exhibited by the subject during a pre-ovulation phase of a menstrual cycle of the subject.

6. Apparatus for monitoring a female subject, the apparatus comprising:

a sensor, configured;

to be disposed at a location selected from the group consisting of;

upon the subject'"'"'s bed, and within the subject'"'"'s bed,

to monitor the subject, while the subject is in her bed, without requiring compliance of the subject, and

to generate a sensor signal in response to the monitoring, the sensor signal being indicative of the subject'"'"'s respiratory rate; and

a computer processor, configured to;

receive the sensor signal,

analyze the sensor signal, by comparing the subject'"'"'s respiratory rate to a respiratory rate previously exhibited by the subject,

based upon comparing the subject'"'"'s respiratory rate to the respiratory rate previously exhibited by the subject, identify whether the subject is in a pregnant state or a non-pregnant state, and

generate an output in response thereto.

7. The apparatus according to claim 6, wherein the computer processor is configured to identify whether the subject is in the pregnant state or the non-pregnant state without determining a temperature of the subject.

8. The apparatus according to claim 6, wherein the computer processor is configured to identify whether the subject is in the pregnant state or the non-pregnant state, using a machine-learning algorithm.

9. The apparatus according to claim 6, wherein the subject'"'"'s bed includes a mattress, and wherein the sensor is configured to be disposed within the subject'"'"'s bed, underneath the mattress of the subject'"'"'s bed.

10. The apparatus according to claim 6, wherein the computer processor is configured to analyze the sensor signal, by comparing the subject'"'"'s respiratory rate to a respiratory rate that was previously exhibited by the subject during a pre-ovulation phase of a menstrual cycle of the subject.
