Abstract

Methods of detecting and predicting ovulation and a period of fertility include determining a series of measures indicative of the basal body temperature of a female human user to identify a temperature change event. The method includes obtaining, within a first 24 hour period, a plurality of first readings of the temperature of the female human user at intervals over a first extended period of at least an hour. The plurality of first readings are then processed to determine at least one first representative temperature reading representative of the basal body temperature of the user for the first extended period and the at least one first representative temperature reading is stored. The method is repeated for at least second and third 24 hour periods and the representative temperature readings are provided for analysis to identify a temperature change event for the female human user.

Claims

1. A data processing device for processing data indicative of a basal body temperature of a female human user to identify a temperature change event for the female human user, the device comprising:

a communication interface for receiving multiple body temperature readings or information derived therefrom from multiple female human users, wherein the readings for each user are uniquely identified;

a processor for identifying temperature readings having one or more characteristics of irrelevant or faulty data and either deleting said readings or labelling them as to be disregarded, for obtaining one or several representative temperature values for each of multiple extended periods, and for analysing the representative temperature values over multiple extended periods to identify a pattern indicative or predictive of ovulation, and wherein the analysis includes using information from values obtained for other female human users;

wherein the processor is configured to store is arranged to store information relevant to fertility or the timing of ovulation for each user associated with a unique identifier securely on a computer file server for secure retrieval by the user associated with the unique identifier;

wherein the processor is configured to receive from the user a request for the information,

wherein the request comprises the unique identifier associated with the user,

wherein the processor is configured to generate and transmit a signal to cause a display to provide a visible indication of the information for display to the user, and

wherein the data processing device is configured to store data for multiple cycles for multiple users and performs said analyzing based on said multiple cycles and multiple users.

2. A data processing device according to claim 1 wherein the device is configured to receive supplementary information based on input from the user and to perform said analysing based on said supplementary information.

3. A data processing device according to claim 2 wherein the supplementary information is based on an indication by the user of the onset of menstruation.

4. A data processing device according to claim 2 wherein the supplementary information is based on an indication by the user of a day when the user has a fever.

5. A data processing device according to claim 2 wherein the temperature readings are obtained from a temperature sensor worn by the user and the supplementary information is obtained from a user input device associated with the temperature sensor.

6. A data processing device according to claim 1 wherein the unique identifier for each user is coded into a temperature sensing apparatus associated with the user.

7. A data processing device according to claim 1 wherein the device is configured to analyse readings obtained overnight.

8. A data processing device according to claim 1 wherein the device is configured to analyse historical data of previous cycles and newly obtained data from a current cycle for the user.

9. A data processing device according to claim 1 wherein the device is configured to transmit arranged to transmit a message to a device associated with the user based on said analysis.

10. A data processing device according to claim 1 wherein the information relevant to fertility or the timing of ovulation is available for secure retrieval by a medical practitioner associated with the user.

11. A temperature sensing system comprising;

a wearable, removable temperature sensor being arranged to be worn by a female human user for sensing her temperature, being associated with a code for uniquely identifying the user'"'"'s temperature readings;

a first an interface for transmitting the temperature readings or information derived therefrom;

the a user terminal comprising an interface for receiving the temperature readings or information derived therefrom from the temperature sensor;

a second an interface for transmitting temperature readings or information derived therefrom to a remote server together with the associated unique code to be analysed in conjunction with data from multiple users to determine a pattern indicative or predictive of ovulation for the female human user, the system further including; and

an input device for receiving an input from the user for indicating supplementary information such as for the onset of menstruation or a fever;

wherein the temperature sensing system is configured to enable storage of data for multiple cycles for multiple users and performs said analyzing based on said multiple cycles and multiple users.

12. A system according to claim 11 wherein the user terminal is arranged to process temperature readings to delete or flag readings having characteristics of irrelevant or faulty data and to provide readings after said deleting or flagging to the remote server for analysis to identify a pattern indicative of ovulation.

13. A system according to claim 11 wherein the temperature sensor is arranged to be worn overnight by the female human user.

14. A system according to claim 13 wherein the system is selectably removable during the day.

15. A system according to claim 11 wherein the user terminal further comprises an interface for receiving from the remote server an indication relating to ovulation of the female human user, following processing of data from multiple users, and an indicator for communicating the indication to the user.

16. A system according to claim 11 wherein the system is configured to filter arranged to filter the temperature readings so that a subset of the temperature readings, or the information derived therefrom, is transmitted to the remote server.

17. A system according to claim 11 further comprising an interface for accessing from the remote server the pattern indicative or predictive of ovulation after the data has been analysed in conjunction with data from multiple users.

18. A method for processing data indicative of a basal body temperature of a female human user to identify a temperature change event for the female human user, the method comprising:

receiving multiple body temperature readings or information derived therefrom from multiple female human users, wherein the readings for each user are uniquely identified;

identifying temperature readings having one or more characteristics of irrelevant or faulty data and either deleting said readings or labelling them as to be disregarded;

obtaining one or several representative temperature values for each of multiple extended periods;

analysing the representative temperature values over multiple extended periods and information from values obtained for other female human users to identify a pattern indicative or predictive of ovulation;

storing information relevant to fertility or the timing of ovulation for each user associated with a unique identifier securely on a computer file server for secure retrieval by the user associated with the unique identifier;

receiving from the user a request for the information, wherein the request comprises the unique identifier associated with the user;

generating and transmitting a signal to cause an interface to provide a visible indication of the information for display to the user; and

storing data for multiple cycles for multiple users and performing said analyzing based on the multiple cycles and multiple users.
