Abstract:
This invention relates to identification systems. An identifier is located at a specific point on some structure which a reading device registers the specific address when placed in proximity to the physical location, hence simplifying and adding certainty to address location, for purposes of commercial use in the nature of delivery or service calls, personal use, as in identifying locations of houses or structures in unfamiliar locations, or for emergency use, such as by police or firefighters.

Description:
[0001]    This invention claims the benefit of U.S. Provisional Application No. 60/322,658, filed Sep. 17, 2001. 
     
    
     
       BACKGROUND OF THE INVENTION  
         [0002]    1. Field of Invention  
           [0003]    The present invention relates generally to identification systems. More specifically, the invention relates to a method for a system and method identifying street locations for buildings, structures, geographic landmarks, and locations by utilizing identification means and a detecting device which can read or recognize the specific locations.  
           [0004]    2. Description of the Related Art  
           [0005]    Identifying street addresses is an age-old problem. Although any variety of means have been tried to urge homeowners, businesses, and property owners to clearly mark and identify, a variety of issues including poor lighting, overgrowth of vegetation, missing markings, vandalism, and simple non-participation all contribute to an absence of a reliable, functional method for identifying. Many devices have been directed to the concept of providing devices to illuminate house identifying information, some even to facilitate automatic house address illuminating displays. Despite this prior art, there is no means for reliably and instantly identifying houses, buildings, structure, and property. Note that this issue and problem is not restricted simply to constructed buildings but is particularly acute with regard to raw land which may need to be identified for a variety of reasons ranging from offering for sale, locating utilities or other easements which are identified by property site, tax assessment, or public safety issues.  
         SUMMARY OF THE INVENTION  
         [0006]    The present invention is generally directed to satisfying the need to quickly and accurately identify property by street address or other identifying means. The problem of an accurate method for use by businesses, organizations and individuals, ranging from public safety to delivery, to convenience are all solved by the present invention.  
           [0007]    In accordance with one preferred embodiment of the present invention, this need can be satisfied by placing bar codes on each piece of property. The bar code is mounted as a stand-alone device, on a stake, or can be mounted to existing structures, either at curbside or on a structure itself. For example, the bar code could be affixed to the mailbox.  
           [0008]    The bar code registers the street number or block number, when read by a bar code reading device.  
           [0009]    Such devices can also be mounted in an automobile dashboard or be an accessory. Existing bar code reading technology is utilized for the purpose of scanning or reading the information from the bar codes. A display on the bar code reading device indicates the number.  
           [0010]    In this way, particularly at night when trying to find a particular house or street number, due to the problem of obstructed numbers or even irregularly numbered streets, the device immediately allows any user to identify the address of any place which is sought.  
           [0011]    In an alternative embodiment, any other identification means such as a transmitter, which broadcasts information can be used, employing, for instance, radio frequency or existing radio or cellular technology so that the reading device for an individual can be a personal digital assistant or other hand-held computer operated wireless telephone or other computer type or microprocessor of device.  
           [0012]    Yet another alternative embodiment of the reading device permits delivery companies such as the postal service, private courier and overnight express companies, package delivery services, utilities, or other service people to readily and instantly identify every address which is sought. In another embodiment of the reader, it is permanently mounted on a delivery or service vehicle of any sort, and uses a display which will register each house or lot number as that house or lot is passed or approached by the delivery or service vehicle. This can even be used, therefore, by small delivery services and companies of a local nature such as dry cleaners, or food delivery persons such as for take-out restaurants.  
           [0013]    In yet another embodiment, this system can also be used by municipalities on road signs or public structures, giving people seeking street and street locations instant identification. The system can be further refined so that the street location signs provide not only the street name but the “block number”, listing all of the addresses to be found between one street and the next cross street A further embodiment provides for identification means indicating street or location identification numbers on either side or all sides of any given intersection.  
           [0014]    Further, the information from any receiver or transmitter device is interfaced with a database which provides further address verification information for individual locations such as linking a company name to a given address, in the form of a directory, such that if, for instance, a delivery vehicle were to pass an address as 145 Main Street, when the bar code or transmitting device encoded, emitted or broadcast the signal for identifying a specific location, the signal is transmitted via modem or other data exchange, or other data communication technology, to a computer data base which displays on the screen the name of the residence, business, institution, and so forth, for that specific address.  
           [0015]    In yet another embodiment, the bar code information interfaces with satellite-based or other global positioning systems (GPS). Such systems, which typically can take a user to a specific street or location, can further rely on the individual bar codes to identify a specific site within a location, identified with even more precision than that provided by the GPS. Existing GPS hand-held devices may be adapted to read the signals or transmissions from the remote bar codes or transponders.  
           [0016]    The transponder or signal emitting devices themselves may be connected to a wired or wireless network, and activated when an inquiry is made by a reading device.  
           [0017]    In open undeveloped, unimproved land, whether public space or private property, locators can be put in unobtrusive locations. Even areas surrounding landmarks at historic or tourist or entertainment sites can be utilized to identify the specific name of the location.  
           [0018]    Amusement parks may utilize the system to identify specific rides or attractions, for instance, within their confines. Shopping malls can broadcast information to passing customers about merchandise, specials or other information.

       DETAILED DESCRIPTION OF THE INVENTION  
       [0025]    [0025]FIG. 1 illustrates an example diagram of a location determination system  100  in accordance with this invention. The system  100  includes a plurality of location identifiers  121 - 129  that are configured to provide an identification of locales  101 - 103 . In accordance with this invention, a mobile location detector  150  is configured to receive the identification of the locales  101 - 103  from the location identifiers  121 - 129 , and to render a location message corresponding to the identifications provided by the location identifiers  121 - 129 .  
         [0026]    In a preferred embodiment of this invention, the identifiers  121 - 129  are remotely accessible by the location detector  150 . In a straightforward embodiment, the identifiers  121 - 129  are bar-code stickers that are attached to structures that are associated with the locales  101 - 103 , and the detector  150  is a bar-code reader that reads the content of each sticker via a visual scanning of the sticker. In a more advanced embodiment, the identifiers  121 - 129  are RFID (Radio Frequency IDentifier) transmitters that communicate an identifier via a radio-frequency transmission. Other means of communicating an identifier from the identifiers  121 - 129  to a detector  150  will be evident to one of ordinary skill in the art in view of this disclosure.  
         [0027]    The identifiers  121 - 129  may identify a single locale  101 ,  102 ,  103 , or a plurality of locales  101 - 103 . For example, individual identifiers  121 - 123  may be located at each locale  101 - 103 , and/or a group identifier  129  may be located at a site that is associated with a plurality of locales, such as a street-corner.  
         [0028]    The identifiers  121 - 129  may provide unique identifications for each locale, or identifications that are part of a hierarchical identification system. That is, for example, the identifications may be unique within a given geographic region, and an identification of the geographic region may need to be provided to the detector  150 . This region identification may be explicit, implicit, or automated. For example, the user may explicitly select a region from a menu to initialize the detector  150 , or the user may download a database that corresponds to the particular region, thereby implicitly configuring the detector  150  for this region. In an automated system, the detector  150  may contain, or be coupled to, a location-determination device, such as a GPS receiver that serves to identify the current geographic region of the detector  150 .  
         [0029]    [0029]FIG. 2 illustrates an example block diagram of a bar-code embodiment  200  of a location determination system in accordance with this invention. In this embodiment  200 , a bar-code  210  is affixed to a structure that is accessible/scan-able by a remote scanning device  220 . The scanning device  220  provides the scanned identifier to a processing device  230 , such as a laptop or palm-top computer system. The encoding of the bar-code  210  may merely correspond to the numeric address of the locale, on the assumption that the user of the system  230  will know the street name to which the number applies, or it may be an index to a database that includes a more complete identification of the locale, as discussed further below.  
         [0030]    [0030]FIG. 3 illustrates an example block diagram of an RFID embodiment  300  of a location determination system in accordance with this invention. In this embodiment, a Radio-Frequency IDentifier (RFID) transmitter  310  is affixed to a structure that is associated with each locale  101 ,  102 ,  103  of FIG. 1 or a plurality of locales  101 - 103 . U.S. Pat. No. 6,265,977, “RADIO FREQUENCY IDENTIFICATION TAG APPARATUS AND RELATED METHOD”, issued 24 Jul. 2001 to Victor Allen Vega and Noel H. Eberhardt, details the design of a typical RFID device, and is incorporated by reference herein. The location detector  150  of FIG. 1 in this embodiment includes an RFID receiver  320  and a processing device  330 , such as a laptop or palmtop computer, or merely a device that displays the information provided by the RFID receiver  320 . Optionally, the detector  150  includes a database  350  that facilitates an identification of the locale or locales based on the information received by the RFID receiver  320 .  
         [0031]    [0031]FIG. 4 illustrates an example block diagram of components of an RFID embodiment of a location determination system  300  in accordance with this invention. In this example embodiment, the system  300  includes an RFID transmitter  310  that comprises a resonance power source  410 , an ID memory  420 , and a transmitter  430 . The resonance power source  410  is configured to provide power to the transmitter  430  upon receipt of an excitation signal at the resonant frequency of the source  410 . A resonance exciter  440  in an RFID receiver  320  is configured to provide this excitation signal at the resonant frequency when activated, via for example, a push-button  445 . That is, a user of the RFID receiver  320  activates the exciter  440  when seeking a location identifier. If there is an RFID transmitter  310  in the vicinity of the receiver  320 , the resonance power source  410  of this transmitter  310  receives the excitation signal, and provides power to the transmitter  430  to transmit the ID  420  of the transmitter  310 . Alternatively, the transmitter  310  may be connected to a continuous power source, and will be configured to continuously transmit the ID  420 , or to transmit the ID  420  upon receipt of a trigger signal from the receiver  320 .  
         [0032]    The RFID receiver  320  includes a receiving device  460  that receives the radio-frequency transmission from the transmitter  310  and a decoder  470  that extracts the ID from this received signal. The received ID is communicated to a processing device  330 . The degree of processing by the processing device  330  is dependent upon the scheme used to convey the location identifying information via the ID  420 . If the ID  420  is an explicit location identifier, such as an ASCII encoding of an address, the processing device  330  can merely be a display device. Alternatively, the ID  420  may be a unique identifier that is used to index explicit location identification information in a database  350 . That is, for example, the database  350  may contain an identification of all locales within a geographic region, and the ID  420  is configured to identify the entry in the database  350  corresponding to the locale at which the ID  420  is located. The processing device  330  in such an embodiment includes a mapper  480  that is configured to provide the appropriate entry in the database  350  for display on a display device  490 , based on the received ID from the transmitter  310  that is in the vicinity of the receiver  320 .  
         [0033]    This invention provides a number of commercial opportunities for facilitating the identification of locales. If the system  300  uses the optional database  350 , a commercial opportunity exists for providing the entries to the database  350  and/or for providing updates or ancillary information for existing entries in the database  350 . For example, if the entries in the database  350  include the address of each locale, the ancillary information could include the name of the owner of the property at the locale, the name of the current resident of the property, contact information regarding a sale of the property, and so on. If the locale is a commercial establishment, the ancillary information could include an advertisement, a reference to a web-site, an online catalog, and so on. In a preferred embodiment, the database  350 , as well as the ancillary information, is downloadable from a web-site, so that the information can be easily updated or corrected. Optionally, the processing system  330  may be configured to provide wireless Internet access, for direct connection to a database  350  and ancillary information that is contained at an Internet-accessible web-site.  
         [0034]    The foregoing merely illustrates the principles of the invention. It will thus be appreciated that those skilled in the art will be able to devise various arrangements which, although not explicitly described or shown herein, embody the principles of the invention and are thus within its spirit and scope. For example, the processing system that is detailed above for the RFID embodiment can be utilized in a bar-code embodiment as well. Additionally, although this invention is presented using the examples of a bar-code embodiment and an RFID embodiment, other embodiments for sensing an identifier at a locale may also be used, including, for example a magnetic strip reader, an infrared transmitter/receiver, and so on. In like manner, the particular partitioning of functions among devices may differ from the example embodiments of FIGS.  2 - 4 . For example, the resonance power source  410  arid transmitter  430  in the RFID transmitter  310  may be a single RF resonant circuit that receives the excitation signal, enters oscillation, and continues in oscillation, thereby entering a transmit mode, when the excitation signal is terminated. In like manner, the display  490  may be incorporated directly into the receiver  320 , so that the combination of components  320  and  330  may be incorporated into a simple hand-held device that reads and displays location-identifying information. These and other system configuration and optimization features will be evident to one of ordinary skill in the art in view of this disclosure, and are included within the scope of the following claims.
