Abstract

A system for detecting unauthorized access to an area includes a sensor configured to be coupled to a body and to detect access to an area inside the body. The sensor is configured to transmit a signal in response to detecting access to the area. The system also includes an alert feature configured to receive the signal and to generate an alert in response to receiving the signal.

First claim

What is claimed is:

1. A system for detecting access to an area, comprising:
a sensor configured to be coupled to a body and to detect access to an area inside the body by an unauthorized personnel member in response to sensing a magnetic field, a pressure, a chemical signature, a biological signature, a nuclear signature, or a combination thereof, wherein the body is inside a vehicle, and wherein the sensor is configured to transmit a signal in response to detecting access to the area;
an alert feature configured to receive the signal and to generate an alert in response to receiving the signal; and
a local interface unit configured to begin harvesting power from an alternating current source upon detecting access to the area and to provide the power to the alert feature.

2. A system for detecting unauthorized access to an area, comprising:
a sensor configured to be coupled to a body to detect access to an area inside the body by an unauthorized personnel member in response to sensing a magnetic field, a pressure, a chemical signature, a biological signature, a nuclear signature, or a combination thereof, wherein the body is inside an aircraft, wherein the sensor is configured to transmit a first signal in response to detecting access to the area, and wherein the area comprises an inventory comprising a first-aid kit;
a controller spaced apart from the sensor and configured to receive the first signal and to transmit a second signal in response to receiving the first signal, wherein the controller comprises a first display configured to allow an authorized personnel member to interface with the system;
an alert feature spaced apart from the sensor and configured to receive the second signal and to generate an alert in response to receiving the second signal, wherein the alert feature comprises a second display configured to allow the authorized personnel member to interface with the system, wherein the alert signals the authorized personnel member to determine whether the unauthorized personnel member has accessed the inventory inside the area and to determine whether the inventory inside the area needs to be replenished, and wherein no alert signals the authorized personnel member that the inventory inside the area is unchanged; and
a local interface unit configured to begin harvesting power from an alternating current source upon detecting access to the area, to provide the power to the alert feature.

3. The system of claim 2 , wherein the body is part of the vehicle, and wherein the alternating current source is a power source of the vehicle.

4. The system of claim 2 , wherein the sensor is coupled to a first side of the body, wherein the alert feature is coupled to a second side of the body, and wherein the controller is coupled to the second side of the body, a side of the body other than the first or second sides, or to a remote surface within the vehicle.

5. The system of claim 2 , wherein the sensor is configured to detect access to the area inside the body by the unauthorized personnel member in response to sensing the magnetic field.

6. The system of claim 2 , wherein the sensor is configured to detect access to the area inside the body by the unauthorized personnel member in response to sensing the pressure.

7. The system of claim 2 , wherein the sensor is configured to detect access to the area inside the body by the unauthorized personnel member in response to sensing the chemical signature.

8. The system of claim 2 , wherein the sensor is configured to detect access to the area inside the body by the unauthorized personnel member in response to sensing the biological signature.

9. The system of claim 2 , wherein the sensor is configured to detect access to the area inside the body by the unauthorized personnel member in response to sensing the nuclear signature.

10. A method for detecting unauthorized access to an area, comprising:
coupling a sensor to a body, wherein the body is inside a vehicle, wherein the sensor is configured to detect a change of state in response to access to an area inside the body by an unauthorized personnel member by sensing a magnetic field, a pressure, a chemical signature, a biological signature, a nuclear signature, or a combination thereof, and wherein the sensor is configured to transmit a signal in response to the change of state;
positioning an alert feature within a first predetermined distance of the sensor, wherein the alert feature is configured to receive the signal, to determine when access to the area inside the body has occurred in response to the signal, and to generate an alert in response to determining that the area inside the body has been accessed; and
positioning a local interface unit within a second predetermined distance of the sensor, the alert feature, or both, wherein the local interface unit is configured to begin harvesting power from an alternating current source upon detecting access to the area and to provide the power to the alert feature.

11. The method of claim 10 , further comprising:
receiving at least one unique identifier and detail data from a very-low-energy radio-frequency communication link of the sensor or the alert feature;
identifying the sensor or the alert feature based upon the unique identifier; and
identifying a timing associated with the change of state detected by the sensor.

12. The method of claim 11 , further comprising determining a remaining battery charge level of the sensor or the alert feature based at least partially upon the detail data.

13. The method of claim 11 , wherein the detail data comprises at least one of security attributes for authentication and encryption, software version history, information about a state of the sensor, time of changes or revisions, or historical records of past events.

14. The method of claim 11 , further comprising determining when access to the area is unauthorized based at least upon the detail data.

15. The method of claim 11 , further comprising generating a report for the sensor or the alert feature, wherein the report indicates at least one of:
whether the area has been accessed,
a timing associated with an inquiry for the report,
a timing associated with an activation of the sensor or the alert feature,
a remaining battery charge level of the sensor or the alert feature, or
location description for the sensor based upon configuration data and the unique identifier.

16. The method of claim 10 , wherein coupling the sensor to the body comprises coupling the sensor to a door of the body, and wherein the door is configured to be opened to provide access to the area.

17. The method of claim 10 , further comprising interfacing with a display at the alert feature to input or receive system status information.

18. The method of claim 17 , wherein the system status information comprises information related to isolating a fault.

19. The method of claim 17 , wherein inputting system status information comprises maintaining software revisions, updates, and security protocols.
