Abstract

A zone access control system is described. The system is particularly suited for controlling access to radioactive or potentially radioactive areas. The system comprises one or more portable devices that are worn or otherwise carried by individuals in the facility or region of interest. The system also comprises one or more intelligent barriers that govern or restrict entry into or exit from, one or more zones of interest. And, the system comprises a computer or computer system to process information and provides control instructions to the barriers and to the portable devices. Various methods of operation are also described.

Claims

1. A system for controlling access by individuals into at least one zone of interest, the system comprising:

a plurality of portable devices each of which is carried by an individual and includes a microprocessor, memory provisions, an on-board power source, and provisions for transmitting information;

at least one intelligent barrier associated with the zone of interest such that the intelligent barrier is selectively operable to allow entry by the individual into the zone of interest or deny entry into the zone of interest, the intelligent barrier including provisions for transmitting information;

a computer system including (i) input provisions for receiving information from at least one of the plurality of portable devices and the at least one intelligent barrier, (ii) processing provisions for executing one or more algorithms using the received information, and (iii) output provisions for providing operating instructions to the at least one intelligent barrier according to the algorithms;

wherein the instructions from the computer system are used to selectively operate the at least one intelligent barrier to thereby allow or deny entry of the individual carrying a portable device into the zone of interest.

2. The system of claim 1 wherein the plurality of portable devices, the at least one intelligent barrier, and the computer system each communicate bi-directionally with one another.

3. The system of claim 1 wherein the portable device is a dosimeter.

4. The system of claim 1 wherein the intelligent barrier is selected from the group consisting of a gate, a turnstile, and a door.

5. The system of claim 1 wherein the intelligent barrier also includes provisions for receiving information from at least one of the portable devices and the computer system.

6. The system of claim 1 wherein the portable device also includes provisions for receiving information from at least one of the intelligent barriers and the computer system.

7. The system of claim 1 wherein the portable device contains information about the individual.

8. The system of claim 1 wherein the portable device contains information about the zone of interest.

9. The system of claim 1 wherein the system controls access into a plurality of zones of interest.

10. The system of claim 1 wherein the intelligent barrier also includes memory provisions for storing information and an electronic processor for processing information utilized in the operation of the intelligent barrier also includes memory provisions for storing information and an electronic processor for processing information utilized in the operation of the intelligent barrier.

11. A method for controlling access into a zone of interest, the method comprising:

providing a system including (i) a portable device, (ii) an intelligent barrier associated with the zone of interest, and (iii) a computer system in communication with the portable device and the intelligent barrier;

assigning the portable device to a user;

transferring information associated with the user including user data to the portable device;

transferring information associated with the zone of interest including entry data to the portable device;

the user presenting the portable device to the intelligent barrier upon attempting to access the zone of interest;

transferring the user data from the portable device to the computer system;

transferring the entry data from the portable device to the computer system;

the computer system assessing whether the user data and the entry data is acceptable for access by the user, and if so, then issuing a signal to the intelligent barrier indicative of allowing access into the zone of interest;

the intelligent barrier receiving the signal and then enabling access by a user into the zone of interest.

12. The method of claim 11 wherein the computer system also assesses whether zone area conditions are satisfactory.

13. The method of claim 11 further comprising:

transferring information including entry statistics from the intelligent barrier to the computer system.

14. The method of claim 11 further comprising:

transferring information from the computer system to the portable device.
