Definitions

• BACKGROUND "Location based" services are currently delivered in the outside environment through hand-held devices such as cell phones, personal digital assistants (PDA), monitors installed in vehicles and the like. This information is made available to a variety of end users. For example, a driver can get an image of a map indicating his or her location, or a delivery person can get directions on how to drive to a desired location.
• Current global positioning systems GPS include receivers which only work where satellite transmitters can reach, thus limiting the system's use to the outdoor environment. Even here, overhead and surrounding obstructions such as trees and urban corridors result in spotty service. For optimum resolution, the user must have an open view to the sky. Also, location based service applications which require accuracy to within meters are not possible because of limitations in GPS resolution.
• Altitude measures in GPS are much more inaccurate than latitude/longitude.
• cellular telephone triangulation based upon measurements of the cell phone's relative distance from multiple cell towers, fails to provide any measure of altitude. Therefore, even if current cellular technology could eventually be developed to the point that it could locate a cell phone or PDA inside a building accurately, it would not provide the altitude information needed to determine the floor on which the user is located. In other words, when using GPS alone, the user (or others) could know his or her location on the X and Y-axes, but not on the Z-axis. Overall spatial resolution of this system is therefore limited to tens of meters.
• location based services would provide "just in time information" delivery of information where it is needed, when it is needed, in the language required and tailored to the recipient.
• the user may want to identify one among many obj ects or destinations in the immediate environment, currently available systems lack specificity in terms of spatial accuracy (precision in location information) needed for a person to, e.g., receive a menu while standing in front of a restaurant, receive hypertext information about a particular object they are viewing in a museum, or receive extended information about signs they see - but cannot read - in a transit terminal.
• IrDA Infrared Data Association
• this protocol was designed specifically for local, sub-meter device-to-device communication (such as notebook computer-to-PDA or PDA-to-PDA communication) and not as an integrated component of a communication network. Since IrDA does not anticipate closely spaced, multiple transmitters operating concurrently, the protocol is unsophisticated in terms of network collision arbitration.
• IrDA is not a good candidate for communications strategy in the task of facilitating label based services where gathering information at a convenient distance (from one of a number of overhead signs in an airport terminal, for example) may be desired.
• IrDA implementations do not anticipate operation in bright sunlight, thus further reducing the medium's effective range in the outdoors.
• RANSI Remote Inf ared Audible Signs
• TALKING SIGNS® Remote Inf ared Audible Signs
• TALKING SIGNS® a short speech message stored in infrared transmitters as labels.
• the user's hand-held receiver converts the transmission from lightwave signals to audible speech messages.
• the receiver is especially designed for relative uniformity of sensitivity indoors or outdoors.
• the infrared beam pattern provides control of range (from several centimeters to over 30 meters) and breadth (an angle of from 6 degrees to 360 degrees) for the message coverage.
• the high degree of spatial selectivity of the RIAS receiver results from the nature of the transmitted frequency modulated (FM) infrared light signals where FM phase lock loop demodulation ensures that only the strongest among many possibly competing signals will be passed to the user.
• the strongest signal in this regard means the signal which has the most signal energy at the receiver and is the result of three factors: (1) the relative power output of competing transmitters, (2) the relative distance from the competing transmitters to the receiver, and (3) the angle of the receiver's lightwave detector relative to each of the competing transmitters; the angle of the receiver being the most prominent factor controlling which label's information is passed to the receiver.
• information to be presented to the user can be stored (1) within the transmitting labeling system itself, (2) within the receiver carried by the user ("flash" memory, CD ROM, etc.) or (3) within some wireless server system communicating with the receiver. If the user seeks additional information to that initially provided by the system, some method of selecting from the contents of a database is required. Label based information is specific to each place or object of interest to the user. This means that the totality of information potentially available to the user, visiting many objects, could be enormous and potentially updated on a moment-by-moment basis. A high bandwidth requirement for communicating voice and graphics to the user is another consideration.

• DETAILED DESCRIPTION OF THE INVENTION The attached Fig. 1 illustrates one embodiment of this invention for a telecommunication system 20 wherein a wireless lightwave radio frequency transceiver 10 receives a lightwave signal A containing a unique identification code, which is associated with a particular object or location within an environment, from a label 12, configured to transmit signal A containing the identification code, where label 12 has a relatively stronger signal as compared with other like labels in the environment.
• Labels 12 are preferably infrared labels such as those transmitters marketed under TALKING SIGNS® and further described in at least U.S. Patent 5,757,530. These TALKING SIGNS® labels are configured to transmit lightwave signals which convey information for non- visual display. Labels 12 are preferably infrared spoken message labels. Labels 12 are disposed at key points throughout the environment. The unique identification code pinpoints the label's exact location to a wireless lightwave transceiver 10. This identification code is used to automatically index into location based services information enabling these services to be invoked by a user for any one among many (labeled) features in the environment regardless ofthe close grouping ofthe labels in either an indoor or outdoor location.
• Transceiver 10 (such as a wireless phone or PDA) is configured to receive the transmitted lightwave signal A and process this signal to obtain the embedded code. Transceiver 10 is further configured to wirelessly transmit and receive radio frequency signals B to and from a telecommunication tower 16 which is in communication with a computer server 18 which contains at least one computer database.
• Computer server
• wireless server 18 is a system of linkage to other servers commonly known as the World Wide Web.
• Server 18 and transceiver 10 interface by transmitting information using radio frequency signal B.
• Server 18 can access the computer database, download information specific to the processed unique identification code from this database to transceiver 10, either from a computer database housed in its own memory or from one or more computer databases found at sites accessed on the World Wide Web.
• Transceiver 10 is configured to communicate the downloaded location based services information from server 18 to a user.
• the information communicated is specific to label 12 which transmitted the lightwave signal A.
• the manner in which the communication of information is carried out can be by transceiver 10 displaying the information as graphical text or symbols on a graphics display which can be a component of transceiver 10 or the communication ofthe information can be accomplished by transceiver 10 generating an audible speech message or both.
• transceiver 10 is configured to at least communicate through telecommunication network 20 with a computer database accessible by server 18.
• transceiver 10 can upload the unique identification code to the computer database through telecommunication network 20 where information associated with the unique identification code is obtained and the associated information is downloaded onto transceiver 10.
• Fig. 2 depicts an embodiment ofthe invention wherein communication system 20 is a wireless area network and server 18 is a computer network such as a local area network which can be housed within the same environment as disposed labels 12.
• Fig. 3 is a block diagram which demonstrates the relationship of the elements of communication system 20.
• three labels 12,12,12 are disposed within an environment.
• Each label 12 repeatedly transmits a lightwave signal such as an IR signal A, which indicates a unique location based identification code for that particular object or location within the environment.
• Transceiver 10 capable of receiving multiple IR signals A from different labels 12,12,12, processes one IR signal A to obtain the unique identification code for a particular label 12.
• IR signal A will be processed by transceiver 10 at any given time will be determined at least by 3 interactive factors: (1) the relative power output of competing labels 12,12,12, (2) the relative distance from the competing labels 12,12,12 to transceiver 10, and (3) the angle ofthe lightwave detector of transceiver 10 relative LR signal A of each of competing labels 12,12,12.
• a user holding transceiver 10 which is a PDA can adjust factor (3) to point the PDA at one particular label 12 and ensure that LR signal A of that label 12 will be processed.
• Transceiver 10 communicates the unique identification code through a wireless area network using radio frequency (RF) signal B to server 18. As shown in Fig. 3, the bidirectional nature ofthe radio frequency communication allows an effective interface between transceiver 10 and server 18.
• RF radio frequency
• This interface allows communication of the unique identification code from transceiver 10 to server 18 where the code will either index to a database residing on server 18, within the area network of server 18, or provide a URL address for accessing a specific web site on the World Wide Web, or both.
• location based information relevant to the location or other characteristics of label 12 can be downloaded from server 18 to transceiver 10 using RF signal B.
• the term download is intended to include all necessary computer protocols and/or computer routines and sub-routines which enable of sharing ofthe desired information between server 18 and transceiver 10.
• This downloaded information can then be communicated to the user in some desirable manner, such as, by an illuminated graphical display of transceiver 10, by transceiver 10 causing an audible signal such as an audible speech signal or audible sound to be generated, by a tactile representation such as Braille, or some combination ofthe three.
• portable transceiver 10 can be handheld or in some other manner be caused to accompany the user.
• Transceiver 10 can be equipped with components or modules, such as lightwave receiver 30 for receiving, for example, analog (e.g., Frequency Shift Keying - FSK) code.
• Processor/display component 32 of transceiver 10 decodes signal A being transmitted from label 12 (not shown) where label 12 identifies objects or destinations in the environment, or other information.
• the code processed by component 32 is then available to radio frequency transceiver module 34.
• Radio frequency transceiver module 34 provides transceiver 10 with the capability to interface with server 18 (not shown).
• these highly accurate, pinpointed, unique identification codes can use any of a multitude of wireless networks (e.g., IEEE802.1 IX), Bluetooth, or wireless packet telecom protocols (e.g., GPRS).
• These codes thus acquired, can act as database addresses to call up the location-based information from either servers available through telecommunications, a local server or, by using the unique identification code as the universal resource locator (URL), directly access location-based information stored on sites
• Lightwave receiver module 30 of transceiver 10 can be the receiver of TALKING SIGNS ®, as previously discussed.
• label 12 which transmits the lightwave signal bearing the unique location code, can also transmit interspersed repeating audible messages to lightwave receiver module 30 as seen in Fig. 4.
• the repeating audible messages are also indicative ofthe location of each particular label 12, whether label
• the power can be supplied by portable means, such as replaceable, rechargeable devices (i.e., for example, batteries or fuel cells).
• portable means such as replaceable, rechargeable devices (i.e., for example, batteries or fuel cells).
• replaceable, rechargeable devices i.e., for example, batteries or fuel cells.
• photovoltaic devices in combination with energy storage devices can be employed.
• label 12 can be configured to obtain electrical power from either the electrical mains wiring ofthe object or location within the environment, by an energy storage/energy production device, such as a battery, or by an energy storage device in operable communication with a photovoltaic device.
• Label 12 remains dormant until it receives an activating signal C from modified transceiver 10.
• this is accomplished by configuring both the circuit of label 12 and the circuit of transceiver 10 so that transceiver 10 is capable of sending an activating signal C (an interrogation signal) to the label, thereby setting label 12 into its active, transmission mode.
• Activating signal C may be either lightwave or radio frequency in nature.
• Fig. 4A depicts an embodiment of the invention wherein transceiver 10 can be seen as having both lightwave receiver module 30 and an activating signal transmitter module 31.
