Patent US8405503
Issued 2013-03-26
System And Method For Creating A Proximity Map Of Living Beings And Objects
A contact or proximity network map defines who and what objects have come in contact of each other including location and time. This map selects the list people who have come in contact with known infected people based on contagious disease epidemiology criteria for the purpose of control its spread, or to prevent radiation poisoning, limit bio-chemicals exposure, etc. This selected list of people then undergoes testing and quarantine procedures. It can monitor hygiene practices and reduce nosocomial infections in hospitals and mitigate the pandemic flu threat by controlling spread and control contamination. It controls people interaction, information flow in a high security environment, control crime or gang activities. Each person or object has a proximity-sensing device with unique ID, which is recorded by the encountered units during contact. This information is stored with time stamp in a relational database. It generates contact maps with real time replication of its database via a central web database for retrieval and analysis at any site.

- 1. A contact tracking system comprising: (a) a plurality of mobile units, each unit being adapted to obtain contact event information including, (i) proximity to another contacted unit, (ii) a unique identifier of the another contacted unit, and (iii) a timestamp of the contact with the another contacted unit; (b) at least one data entry device adapted (i) to receive contact event information from the plurality of mobile units; and (ii) to upload contact event information to a database; and (c) a computer adapted to: (i) receive contact event information, (ii) maintain a database of contact event information, (iii) identify a first set of mobile units that were in contact with a mobile unit of interest, and (iv) identify a second set of mobile units that were in contact with a mobile unit of the first set.
- 16. A method of tracking contacts among a plurality of mobile units comprising: (a) obtaining contact event information using a plurality of mobile units, said contact event information including, (i) proximity to another contacted unit, (ii) a unique identifier of the another contacted unit, and (iii) a timestamp of the contact with the another contacted unit; (b) transmitting contact event information from the plurality of mobile units to at least one data entry device; (c) uploading contact event information from the at least one data entry device to at least one computer; (d) maintaining a database of contact event information using at least one computer; and (e) in response to a request for a history of contacts with a mobile unit of interest, (i) identifying a first set of mobile units that were in contact with the mobile unit of interest, and (ii) identifying a second set of mobile sensing units that were in contact with a mobile unit of the first set.
- 31. A contact tracking system comprising: (a) a plurality of mobile units, each unit being adapted to obtain contact event information including, (i) proximity to another contacted unit, (ii) a unique identifier of the another contacted unit, and (iii) a timestamp of the contact with the another contacted unit; (b) at least one data entry device adapted to: (i) receive contact event information from the plurality of mobile units; and (ii) upload contact event information to a database; and (c) a computer adapted to: (i) receive contact event information, and (ii) maintain a database of contact event information; wherein at least one of the computer and a data entry device is adapted to condense redundant contact event information by eliminating complementary contact event information.
- 49. A method of tracking contacts among a plurality of mobile units comprising: (a) obtaining contact event information using a plurality of mobile units, said contact event information including, (i) proximity to another contacted unit, (ii) a unique identifier of the another contacted unit, and (iii) a timestamp of the contact with the another contacted unit; (b) transmitting contact event information from the plurality of mobile units to at least one data entry device; (c) uploading contact event information from the at least one data entry device to at least one computer; and (d) maintaining a database of contact event information using at least one computer; wherein at least one of the computer and a data entry device condenses redundant contact event information by eliminating complementary contact event information.
