System, method and device to interrogate for the presence of objects
First Claim
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.

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.

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. - View Dependent Claims (8, 9, 10, 11, 12)

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. - View Dependent Claims (14, 15)
