Abstract

A method and an apparatus are provided for Radio Frequency Identification (RFID). An RFID base unit is provided that can communicate with at least two different types of RFID tags that are commercially available. Additionally, the RFID base unit can communicate with any number of devices, including but not limited to computer networks, which allow for dynamic access and updates to tailor the RFID base unit for virtually any situation. Particularly, the RFID base unit would be useful in safety and/or security applications to enable and disable automated devices.

Claims

1. A Radio Frequency Identification (RFID) base unit, comprising:

Radio Frequency (RF) circuit adapted to communicate with at least a first and a second RFID circuit type of a plurality of RFID circuit types; and

a control module including processor means at least coupled to the RF circuit, the processor means of said control module being configured to communicate with external devices through at least a first and a second connection standard of a plurality of connection standards.

2. The RFID base unit of claim 1, wherein the control module is at least configured to be in communication with a computer network.

3. The RFID base unit of claim 1, wherein the plurality of connection standards further comprises at least two of a group comprising BlueTooth, RS232, Universal Serial Bus (USB), Ethernet, Wireless, T-carrier connections, FIREWIRE, Optical fiber, ZIGBEE, and Voice over Internet Protocol (VoIP).

4. The RFID base unit of claim 1, wherein the external device is an automated device.

5. An apparatus for securing an external device with a RFID base unit, comprising:

means for providing the RFID base unit adapted to communicate with at least a first and a second RFID circuit type of a plurality of RFID circuit types;

means for interfacing at least one RFID circuit by the RFID base unit, wherein the at least one RFID circuit is a first or a second RFID circuit type; and

processor means for communicating indicia of engagement or disengagement to effect control of the external device through at least one communication standard of a plurality of communication standards, once the at least one RFID circuit interfaces the RFID base unit.

6. The apparatus of claim 5, wherein the means for communicating further comprises means for disengaging the external device when the at least one RFID circuit is engaged.

7. The apparatus of claim 5, further comprising means for relaying information relating to engagement or disengagement to a computer network.

8. The apparatus of claim 5, wherein said processor means is configured to determine if the at least one RFID circuit is allowed to enable or disable the external device.

9. An apparatus comprising an RFID base unit incorporating a processor wherein the base unit is at least configured to employ two or more connection standards of a plurality of connection standards and said processor is configured for outputting at least one signal adapted to engage or disengage at least one device through at least one connection standard when in communication with an RFID circuit.

10. The apparatus of claim 9, wherein the plurality of communication standards further comprises BlueTooth, RS232, Universal Serial Bus (USB), Ethernet, Wireless, T-carrier connections, FIREWIRE, Optical fiber, ZIGBEE, and Voice over Internet Protocol (VoIP).

11. The apparatus of claim 9 wherein the RFID base unit is adapted to communicate with at least a first and a second RFID circuit type of a plurality of RFID circuit types.

12. A RFID base unit comprising:

RF (Radio Frequency) circuitry adapted for communicating with at least one of a plurality of RFID circuit types;

processor means operable to determine if a RFID circuit type presently being communicated with is allowed to communicate with a device external to said RFID base unit signal connection ports configured to communicate with devices external to said RFID base unit, said ports outputting signals in accordance with at least two different connection standards.

13. The apparatus of claim 12, wherein the connection standards comprise at least two of BlueTooth, RS232, Universal Serial Bus (USB), Ethernet, Wireless, T-carrier connections, FIREWIRE, Optical fiber, ZIGBEE, and Voice over Internet Protocol (VoIP).

14. The apparatus of claim 12, wherein said processor means is further operable to communicate a signal to the external device through at least one of said signal connection ports after the determination is made.

15. The apparatus of claim 12, wherein said signal connection ports configured to communicate with devices external to said RFID base unit additionally include at least one universal I/O port.
