AI Technical Summary

Benefits of technology

Enables users to rapidly and reliably check the presence of personal items and determine their last known location, simplifying the tracking process and allowing for real-time monitoring and retrieval of missing items, even when traveling.

Problems solved by technology

This system requires an external and separate interrogator because of the small size of a watches and the size constraints on RFID interrogators.
And while useful at notifying the user of missing items, the system cannot assist in locating the missing item or indicating where the item was last detected to narrow the range of possible locations when searching for the item.

Embodiment Construction

[0015]Referring to FIG. 1, a block diagram of an item tracking system according to one embodiment of the invention is shown. The item tracking system 8 includes a tracker 10 accessible to a user through a user interface 12. The tracker 10 is in communication with a Radio Frequency Identification (RFID) detector 13, which includes an RFID interrogator 14 and an RFID receiver 15, each of which is in turn in communication with a radio frequency interface 16. The tracker 10 is also in communication with a memory 18, which may be any sort of memory accessible by the tracker including RAM stored within the tracker itself or a database within a mobility service provider's core network infrastructure. The tracker is also in communication with a location detector 20. The item tracking system 8 is preferably located within a personal digital assistant (PDA) or within a cellular phone, although the system may be located within other ubiquitous personal communication devices such as laptop comp...

Abstract

A system and method are provided for allowing users to verify the presence of personal items. RFID tags are attached to personal items, and the items are entered into a list. The user makes travel lists from the list of items. When traveling, the user queries the system to determine whether all personal items in the travel list are within range of the system. The system checks for the presence of the RFID tags associated with the items in the travel list. If any RFIDs are not present, the user is alerted. Optionally, the system updates the last known location of items whenever checking for the presence of personal items, so that if an item is not found the user can determine where the item was last known to have been.

Description

FIELD OF THE INVENTION[0001]The invention relates to radio frequency identification, and more particular to a system for monitoring the presence of objects.BACKGROUND OF THE INVENTION[0002]People often carry important items with them, such as passports, plane tickets, watches, medicine, eyeglass cases, security cards, laptop computers, car keys, AC adapter plugs, cameras, cell phones, or even gold pens. When traveling, either long distances or simply to a business meeting, people often pack and unpack these items, or carry the items in more than one bag. These items are therefore sometimes left behind when leaving taxis, packing for vacation, checking out of a hotel, or leaving a business meeting. Even if not left behind, a person must worry about ensuring that all important items are with him or her.[0003]Several systems exist for using radio frequency identification (RFID) for tracking or identifying objects. RFID kits can be purchased, and RFID tags placed on items. The RFID tag ...
