Personal item reminder
First Claim
1. A method of detecting the presence of items labeled with radio frequency identification (RFID) tags, comprising:
- storing a current list of at list one item;
in response to a query by a user, detecting whether the RFID tag of each item in the current list is within detection range; and
for each item whose RFID tag is not within detection range, notifying the user that the item is missing.

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.

9. A system for detecting the presence of items labeled with radio frequency (RFID) tags, comprising:
-
a memory for storing a current list of at least one item;
an RFID interrogator for sending signals to trigger RFID tags;
an RFID receiver for receiving and identifying signals transmitted by RFID tags; and
a tracker for receiving a query from a user through a user interface, for instructing the RFID interrogator which of at least one RFID is to be searched for, for receiving from the RFID receiver an identification of any items in the current list for which the RFID tag is not within detection range, and for displaying on the user interface an identification of any items for which the RFID tag is not within detection range. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A computer-readable medium storing instructions for detecting the presence of items labeled with radio frequency identification (RFID) tags, comprising:
-
instructions for receiving a query from a user;
instructions for retrieving a current list from a memory in response to the query, the current list including at least one RFID;
instructions for prompting an RFID detector to determine whether each RFID in the current list is within detection range, in response to the query; and
instructions for notifying the user of items whose RFID is not within detection range. - View Dependent Claims (18)

19. A method of detecting the presence of items labeled with radio frequency identification (RFID) tags, comprising:
-
selecting an item from an item list;
in response to a query by a user, repeatedly detecting whether the RFID tag of the item is within detection range; and
if the RFID tag of the item is within detection range, notifying the user that the item is within detection range. - View Dependent Claims (20)

21. A system for detecting the presence of items labeled with radio frequency (RFID) tags, comprising:
-
a memory for an RFID associated with an item;
an RFID interrogator for sending signals to trigger RFID tags;
an RFID receiver for receiving and identifying signals transmitted by RFID tags; and
a tracker for receiving a query from a user through a user interface identifying the item, for repeatedly instructing the RFID interrogator with the RFID associated with the item until a halt input is received from the user, for receiving from the RFID receiver an identification of whether an RFID tag having the RFID is within detection range, and for notifying the user when the RFID tag is within detection range. - View Dependent Claims (22)
