Abstract

This invention provides an electronic proximity apparatus and a surveillance method using such an apparatus for alerting individuals that are exposed to a contagious disease. When a person becomes symptomatic and is diagnosed as positive for a given contagious agent, individuals that have recently maintained a threshold proximity with respect to an infected individual are notified and advised to seek immediate medial care. Treatment of individuals in the very early phases of infection (pre-symptomatic) significantly reduces contagiousness of the infected population first exposed to the contagious disease, thus preventing spread of the disease throughout the general population.

Claims

1. A pre-symptomatic surveillance and alert method, comprising:

distributing a separate personal apparatus to each human of a plurality of humans in a region, wherein each said apparatus comprises a proximity transceiver and a data storage device, wherein said proximity transceiver comprises means for transmitting proximity data to a computer controller and to each other said separate personal apparatus during a data acquisition time period, wherein said proximity transceiver further comprises means for receiving a notification from said controller;

diagnosing a contagious disease in at least one infected human of said plurality of humans;

downloading to said computer controller said proximity data from each said apparatus to produce downloaded data, wherein said computer controller analyzes said downloaded data to determine if at least one human of said plurality of humans requires notification, wherein notification is required if the personal apparatus of said at least one human is located within a predefined distance from the personal apparatus of said at least one infected human, wherein said computer controller further comprises means for transmitting said notification to the personal apparatus of said at least one human;

analyzing with said computer controller said downloaded data to determine if said at least one human of said plurality of humans requires said notification; and

transmitting said notification to the personal apparatus of said at least one human if said notification is required.

2. The method of claim 1, further comprising treating said at least one human for said contagious disease.

3. The method of claim 1, wherein said proximity transceiver and said storage device are integrated into a personal apparatus selected from the group consisting of a cell phone, a pager, a personal identification card, a laptop computer, and a personal digital assistants (PDA).

4. The method of claim 1, wherein said proximity transceiver uses radio frequencies.

5. The method of claim 1, wherein said proximity transceiver uses optical frequencies.

6. The method of claim 1, wherein said proximity transceiver uses a wireless communication standard.

7. The method of claim 6, wherein said wireless communication standard includes IEEE802.

8. The method of claim 6, wherein said wireless communication standard includes a frequency band of about 2.4 GHz.

9. The method of claim 1, wherein said proximity transceiver has an operating range of up to 150 feet.

10. The method of claim 1, wherein said proximity transceiver has an operating range of up to 333 feet.

11. A pre-symptomatic surveillance and alert system, comprising:

a computer controller; and

a plurality of personal apparatuses, wherein each personal apparatus of said plurality of personal apparatuses comprises a proximity transceiver and a data storage device, wherein said proximity transceiver comprises means for transmitting proximity data to said computer controller and to other said personal apparatuses during a data acquisition time period, to produce downloaded data, wherein said proximity transceiver further comprises means for receiving a notification from said computer controller, wherein said computer controller analyzes said downloaded data to determine if at least one human of said plurality of humans requires notification, wherein notification is required if a diagnosis is made of a contagious disease in at least one infected human of said plurality of humans and the personal apparatus of said at least one human is located within a predefined distance from the personal apparatus of said at least one infected human, wherein said computer controller further comprises means for transmitting said notification to the personal apparatus of said at least one human.

12. The network of claim 11, wherein said proximity transceiver and said storage device are integrated into a personal device selected from the group consisting of a cell phone, a pager, a personal identification card, a laptop and a personal digital assistant.

13. The network of claim 12, wherein said transceiver utilizes radio frequencies.

14. The network of claim 12, wherein said transceiver utilizes optical frequencies.

15. The network of claim 12, wherein said transceiver is adapted to operate using a wireless communication standard.

16. The network of claim 15, wherein said wireless communication standard includes IEEE802 technology.

17. The network of claim 15, wherein said wireless communication standard includes a frequency band of about 2.4 GHz.

18. The network of claim 11, wherein each said personal apparatus comprises a multi-hop functionality to extend a communication range.

19. The network of claim 11, where said computer controller is integrated into a laptop computer.
