Abstract

An incident alert system enables a plurality of users to participate in a collaborative process to report and be alerted of incidents such as emergencies or hazards. A user uses a networked mobile phone with geo-positioning capability to communicate with a server to report incidents and to inquire about potential incidents of interest based on the user'"'"'s current geographic position. Reports of incidents are transmitted to the server accompanied by the current position of the user/mobile phone. A user'"'"'s mobile phone is preferably configured to automatically submit periodic inquiries to the server based on the user'"'"'s location. Upon receipt of an inquiry from a user, the system queries a database to identify reports of potential interest to the inquiring user. The system analyzes the reports to determine whether to alert the inquiring user of a potential incident of interest.

Claims

1. A method for sending alerts of incidents based on geographic position and time, the method comprising:

receiving reports of incidents reported by users through a plurality of networked mobile devices;

storing an indication of each report in a database in association with a geographic position and a time;

receiving an inquiry transmitted automatically, as one of a sequence of periodic inquiries, by a networked mobile device of an inquiring user;

identifying a geographic position associated with the inquiry;

identifying a geographic range related to the identified geographic position;

identifying a temporal range related to a present time;

querying the database based on the temporal range and the geographic range to obtain a results set of reports;

calculating a score based on the results set of reports; and

in response to determining that the score exceeds a threshold, sending an alert to the inquiring user.

2. The method of claim 1, wherein each incident can be:

an emergency, a hazard, or a request for assistance.

3. The method of claim 1, further comprising:

for the received inquiry and each of a plurality of prior inquiries transmitted by and received from a plurality of a networked, mobile devices, storing an indication of the inquiry in the database in association with a geographic position and a time; and

querying the database based on the temporal range and the geographic range to obtain a results set of inquiries,

wherein the calculation of the score is further based on the results set of inquiries.

4. The method of claim 1, wherein the score is further based on an elapsed time between the time associated with each report in the results set of reports and the time associated with the inquiry.

5. The method of claim 1, wherein the score is further based on a distance between the geographic position of each report in the results set of reports and the geographic position associated with the inquiry.

6. The method of claim 1, wherein at least one of the received reports includes the geographic position that is stored in association with the indication of the report.

7. The method of claim 1, wherein the geographic position associated with the inquiry is automatically determined by the inquiring user'"'"'s networked mobile device.

8. The method of claim 1, further comprising, identifying a direction of travel associated with the inquiry, wherein the identified geographic range is further related to the identified direction of travel.

9. The method of claim 1, further comprising, identifying a direction of travel associated with the inquiry, wherein the indication of each report is stored in the database further in association with a direction of travel, and wherein the database is queried further based on the identified direction of travel.

10. The method of claim 1, further comprising, identifying a velocity associated with the inquiry, wherein the identified geographic range is further related to the identified velocity.

11. The method of claim 1, further comprising, identifying a velocity associated with the inquiry, wherein the indication of each report is stored in the database further in association with a velocity, and wherein the database is queried further based on the identified velocity.

12. A non-transitory computer readable medium for sending alerts of incidents based on geographic position and time, the computer readable medium containing instructions which, when executed by a computer system, cause the computer system to perform the functions of:

receiving reports of incidents reported by users through a plurality of networked mobile devices;

storing an indication of each report in a database in association with a geographic position and a time;

receiving an inquiry transmitted automatically, as one of a sequence of periodic inquiries, by a networked mobile device of an inquiring user;

identifying a geographic position associated with the inquiry;

identifying a geographic range related to the identified geographic position;

identifying a temporal range related to a present time;

querying the database based on the temporal range and the geographic range to obtain a results set of reports;

calculating a score based on the results set of reports; and

in response to determining that the score exceeds a threshold, sending an alert to the inquiring user.

13. The computer readable medium of claim 12, wherein each incident can be:

an emergency, a hazard, or a request for assistance.

14. The computer readable medium of claim 12, wherein the instructions cause the computer system to perform the further functions of:

for the received inquiry and each of a plurality of prior inquiries transmitted by and received from a plurality of a networked mobile devices, storing an indication of the inquiry in the database in association with a geographic position and a time; and

querying the database based on the temporal range and the geographic range to obtain a results set of inquiries,

wherein the calculation of the score is further based on the results set of inquiries.

15. The computer readable medium of claim 12, wherein the score is further based on an elapsed time between the time associated with each report in the results set of reports and the time associated with the inquiry.

16. The computer readable medium of claim 12, wherein the score is further based on a distance between the geographic position of each report in the results set of reports and the geographic position associated with the inquiry.

17. The computer readable medium of claim 12, wherein at least one of the received reports includes the geographic position that is stored in association with the indication of the report.

18. The computer readable medium of claim 12, wherein the geographic position associated with the inquiry is automatically determined by the inquiring user'"'"'s networked mobile device.

19. The computer readable medium of claim 12, wherein the instructions cause the computer system to perform the further function of identifying a direction of travel associated with the inquiry, wherein the identified geographic range is further related to the identified direction of travel.

20. The computer readable medium of claim 12, wherein the instructions cause the computer system to perform the further function of identifying a direction of travel associated with the inquiry, wherein the indication of each report is stored in the database further in association with a direction of travel, and wherein the database is queried further based on the identified direction of travel.

21. The computer readable medium of claim 12, wherein the instructions cause the computer system to perform the further function of identifying a velocity associated with the inquiry, wherein the identified geographic range is further related to the identified velocity.
