Abstract

A system, method and device to interrogate for the presence of objects, to prevent the inadvertent separation of the objects from their owner. An owner is alerted when they are separated from the objects by determining when a trigger event occurs, such as a person leaving and/or entering a particular monitored area or location. These monitored areas can be retrofitted with an electronic interrogation device that monitors local conditions to determine whether a user is entering or leaving the monitored area to trigger an interrogation of the personal items. The interrogation device is constructed and arranged to communicate with the objects to determine whether the objects are with the owner. The interrogation device automatically determines the presence of a particular object at the monitored environment and automatically generates a notification when needed. The system further controls functionality of the objects, according to illustrative embodiments, when the object is present.

Claims

1. An interrogator device that monitors at least one object, the device comprising:

a sensor that detects when a trigger event occurs, by detecting when a power output measured at a vehicle power port by a pluggable device inserted into the power port exceeds a threshold value ranging between approximately 12.0 V and 14.6 V, and when the power output at the vehicle power port exceeds the threshold value, the sensor sends a signal to initialize interrogation for the at least one object to determine whether the at least one object is within a detectable range of the interrogator device;

a controller that, when the at least one object is outside the detectable range of the interrogator device, generates a notification; and

wherein the interrogator device is constructed and arranged to store identifying data for the at least one object to determine when the at least one object is within the detectable range of the interrogator device;

wherein the sensor comprises a filter that requires a minimum time period of the power output falling below the threshold value to be considered a second trigger event.

2. The interrogator device of claim 1 wherein the interrogator device determines when the at least one object is within the detectable range of the interrogator device by Bluetooth communication established between the interrogator device and the at least one object.

3. The interrogator device of claim 1 wherein the controller is constructed and arranged to monitor at least another object to determine whether the at least another object is within the detectable range of the interrogator device.

4. The interrogator device of claim 1 wherein the interrogator device comprises a device pluggable into a power port of a vehicle and the power output is detected from the power port.

5. The interrogator device of claim 1 wherein the at least one object comprises one of a cell phone, a personal digital assistant (PDA), a dongle, a wallet, a purse, and a portable computer.

6. The interrogator device of claim 1 wherein the detectable range of the interrogator device is specified by the manufacturer of the interrogator device and is in the range of up to 6 feet.

16. The interrogator device of claim 1 wherein the controller is constructed and arranged to control functionality of the at least one object when the at least one object is within the detectable range of the interrogator device.

17. The interrogator device of claim 1 wherein the at least one object comprises a dongle that is capable of providing power to a cell phone of a user.

18. The interrogator device of claim 1 wherein the controller is constructed and arranged to generate a notification when both the at least one object and at least another object are outside the detectable range of the interrogator device, and to not generate a notification when either the at least one object or the at least another object are within the detectable range of the interrogator device.

19. The interrogator device of claim 1 wherein the threshold value ranges between approximately 13.5 V and 13.9 V.

7. A method for monitoring at least one object, the method comprising the steps of:

providing an interrogator device that includes a sensing circuit to determine when a trigger event occurs;

monitoring an electrical noise output or a power output of a power port of a vehicle by a pluggable device inserted into the power port and determining that the trigger event occurs when the noise output or the power output of the power port of the vehicle exceeds a threshold value ranging between approximately 12.0 V and 14.6 V;

determining whether the at least one object is within a detectable range of the interrogator device when the trigger event occurs, based upon transmitting data stored in the interrogator device, the data corresponding to the at least on object; and

generating a notification when the at least one object is outside the detectable range of the interrogator when the trigger event occurs;

wherein the step of monitoring the electrical noise output or the power output of the vehicle comprises applying a filter that requires a minimum time period of the electrical noise or the power output falling below the threshold value to be considered a second trigger event.

8. The method of claim 7 wherein the trigger event is at least one of the vehicle being turned on, the vehicle being turned off and the GPS location of the vehicle.

9. The method of claim 7 further comprising the step of:

controlling functionality of the at least one object when the at least one object is within the detectable range of the interrogator device.

10. The method of claim 7 wherein generating the notification occurs on at least one of the interrogator device and the at least one object.

11. The method of claim 7 wherein the detectable range of the interrogator device is approximately up to 8 feet.

12. The method of claim 7 wherein the detectable range of the interrogator device is approximately up to 30 feet.

13. A system that monitors at least one object, the system comprising:

an interrogator device including a sensor having a detectable range within which the interrogator device interrogates for the presence of at least one object; and

a communication module on the at least one object, in communication with the interrogator device, to monitor an electrical noise output or a power output of a power port of a vehicle by a pluggable device inserted into the power port of the vehicle and, wherein a triggering event occurs when the electrical noise output or the power output of the power port of the vehicle exceed a threshold value, the sensor sends a signal to determine whether the at least one object is within the detectable range of the interrogator device and generate a notification when the at least one object is outside the detectable range of the interrogator device;

wherein the communication module comprises a filter that requires a minimum time period of the power output falling below the threshold value to be considered a second trigger event.

14. The system of claim 13 wherein the communication module is Bluetooth equipped and the interrogator device is Bluetooth equipped to establish Bluetooth communication between the interrogator device and the at least one object to thereby determine whether the at least one object is within the detectable range of the interrogator device.

15. The system of claim 13 wherein the at least one object is one of a cell phone, a personal digital assistant (PDA), a dongle, a wallet, a purse, and a portable computer.
