Abstract

A safety device (SD) with wireless ability, and fixed and mobile, multispectral sensors in an urban region is used for improved protection of a pedestrian, who contacts it via a cellphone. SD tracks and records her and her interactions with others, who might also be tracked if the interactions are suspicious. SD offers her access to a Safety Kiosk (SK) as a shelter against a possible hostile person, where the SK is a multipurposed structure with some other primary use, like an Automated Teller Machine enclosure. SD can archive messages and calendar data associated with the pedestrian and germane to upcoming meetings with others.

Claims

1. A use of a Safety Device (SD) with wireless protocols to communicate with a cellphone;

having multispectral imaging sensors in an urban region, where the sensors might be fixed or mobile, located on the ground or on walls, roofs, ceilings or airborne;

where the sensors have image recognition methods to track a pedestrian;

with acoustic microphones, to record conversations;

where a pedestrian (Jane) contacts SD with her cellphone, giving the phone'"'"'s location, and SD then tracks her with imaging sensors;

where SD uses prior knowledge of its surroundings to improve the image recognition tracking of Jane or other persons.

2. The method of claim 1, where, when Jane contacts SD, she points her phone at another person, and the phone'"'"'s orientation is transmitted to SD, which then also tracks the person.

3. The method of claim 1, where, when Jane contacts SD, she points her phone at a vehicle, and SD then tracks any persons emerging from the vehicle and interacting with Jane;

where SD optionally extracts the license of the vehicle and queries a government database with it.

4. The method of claim 1, where Jane'"'"'s phone periodically transmits a beacon to improve SD'"'"'s tracking of her.

5. The method of claim 4, where Jane'"'"'s phone has a pseudorandom bit sequence in its beacon, where this sequence is known to SD.

6. The method of claim 1, where if a person comes into contact with Jane, any conversation is recorded and analysed for stress or excessive volume;

and the person is tracked by SD.

7. The method of claim 6, where if the person goes into a vehicle, or was backtracked as coming from a vehicle, SD extracts its license from optical character recognition of the license plate, and queries a government database with it;

if the vehicle is stolen, SD contacts the police and Jane'"'"'s cellphone.

8. The method of claim 7, where if the person leaves in a vehicle, SD contacts a Vehicle Ad Hoc Network (VANET) that may be present on the roads, with a description of the vehicle, to have the VANET track it.

9. The method of claim 1, where SD coordinates with another similar device (SD′

), so that coverage of Jane is maintained between sensors of SD and SD′

, when SD relinquishes coverage.

10. The method of claim 1, when Jane contacts SD with her cellphone, and she is not in the image coverage of any of its sensors, then SD moves its mobile sensors to bring her within coverage;

where SD replies with a suggested trajectory for Jane, to bring her within coverage of its sensors.

11. The method of claim 1, where SD contacts a Safety Kiosk (SK) enclosure that can offer shelter against other persons or the weather;

where SD decides this based on a request from Jane, or from biometrics of her transmitted by her phone that suggests she needs assistance, or from observing that a stranger following her is recognised as a suspect in a government database;

where SD gives directions to Jane to proceed to the SK;

where SD instructs SK to admit Jane;

where, if Jane enters SK, SD directs SK to close and not admit anyone else.

12. The method of claim 11, where an SK is also used as an enclosure for an Automated Teller Machine.

13. The method of claim 11, where an SK is also used as a single occupant toilet.

14. The method of claim 11, where an SK is a double door entrance to a building.

15. The method of claim 1, where Jane is in a Personal Mobility Device (PMD), and it contacts SD for a route through a region, and the route is downloaded and automatically executed on the PMD.

16. The method of claim 1, where Jane'"'"'s phone has an electronic agent that downloads to the phone, calendar and map data and messages relating to or near the current time, appointment or location, and uploads these to SD for archival.

17. The method of claim 16, where the archival includes copying destinations (e.g. webpages) pointed to by links in the uploaded data.
