Abstract
Abstract Methods and systems for locating objects are disclosed. An electronic tag is attached to an object before storing the object. The electronic tag is identifiable by a unique response code. The response code and information pertaining to the object are recorded and the object may then be stored. To locate the object, the response code is entered into an interrogator. The interrogator sends a signal that causes the tag to emit a sound. The system thus allows for random storage of objects and is also useful for locating misplaced objects.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
A document locator system comprising: an electronic tag identifiable by a response code and physically adapted to be attached to a document; an interrogator having a transmitter and a receiver the transmitter operable to transmit the response code; and a location marker, wherein, in response to the interrogator transmitting the response code, the electronic tag sends a first signal to the location marker and a second signal is transmitted to the interrogator, in which the second signal is indicative of the proximity of the electronic tag to the location marker and, hence, the location of a document attached to the electronic tag.
Claim 2
Dependent Claim
102 words
A document locator system comprising: an electronic tag identifiable by a response code and physically adapted to be attached to a document; an interrogator having a transmitter and a receiver the transmitter operable to transmit the response code; and a location marker, wherein, in response to the interrogator transmitting the response code, the electronic tag sends a first signal to the location marker and a second signal is transmitted to the interrogator, in which the second signal is indicative of the proximity of the electronic tag to the location marker and, hence, the location of a document attached to the electronic tag.
Claim 3
Dependent Claim
30 words
The system of claim 1 wherein the interrogator further comprises a display, and wherein the interrogator provides a visual indication in the display of the location of the electronic tag.
Claim 4
Dependent Claim
22 words
The system of claim 1 wherein the location of electronic tag relative to the location marker is displayed on a display device.
Claim 5
Dependent Claim
61 words
The system of claim 3 further comprising: a storage device for storing the response code; and a processor in communication with the storage device, the interrogator and the display device, wherein the processor is operable to cause the interrogator to transmit the response code and to display an indication of the tag's proximity to the location marker on the display device.
Claim 6
Dependent Claim
159 words
The system of claim 4 further comprising a folder, wherein the electronic tag is attached to the folder, and further comprising: a document having an identifier label providing an identification code, the document further characterized by a status, wherein the status indicates whether the document is in the folder or not; a label reader for reading the identification code provided by the identifier label on the documents each time the document is placed in, or removed from, the folder, wherein, the label reader is in communication with the processor and wherein the processor is operable to create and store a record comprising the identification code from the identifier label, the status of the document, and the response code of the electronic tag, and further operable to provide an indication of the folder's proximity to the location marker when the record is accessed so that the location and the status of the document may be determined by accessing the record.
Claim 7
Independent Claim
113 words
A method for locating a document comprising the steps of: (a) attaching an electronic tag to the document, which electronic tag is characterized by a response code; (b) recording the response code and descriptive information concerning the document in a storage means; (c) transmitting the response code using an interrogation device; (d) sending a first signal from the electronic tag to a location marker in response to transmitting the response code, and also sending a second signal from the electronic tag to the interrogation device, in which the second signal is indicative of the proximity of the electronic tag to the location marker; and (e) locating the document based on the second signal.
Claim 8
Independent Claim
113 words
A method for locating a document comprising the steps of: (a) attaching an electronic tag to the document, which electronic tag is characterized by a response code; (b) recording the response code and descriptive information concerning the document in a storage means; (c) transmitting the response code using an interrogation device; (d) sending a first signal from the electronic tag to a location marker in response to transmitting the response code, and also sending a second signal from the electronic tag to the interrogation device, in which the second signal is indicative of the proximity of the electronic tag to the location marker; and (e) locating the document based on the second signal.
Claim 9
Dependent Claim
28 words
The method of claim 6 wherein the step of locating further comprises viewing a display that provides the location of the electronic tag relative to the location marker.
Claim 10
Dependent Claim
37 words
The method of claim 6 wherein step (b) further comprises forming a record and storing the record in a computer storage means and wherein step (c) further comprises querying the record for the location of the document.
