Definitions

  • This invention relates generally to an electronic information display system, and, more particularly, to a computer based system for displaying pricing, advertising, and other specialized information at remote display modules which are either optically or electronically connected to a central computer.
  • a POS system generally has one or more automated check-out terminals which is capable of sensing and interpreting the Universal Product Code (UPC) printed on each item of merchandise to be checked out.
  • UPC Universal Product Code
  • Each of these terminals is connected to a computer which processes the UPC information.
  • the computer's data base includes a list of items of merchandise on sale, a UPC for each of these items, and various types of information, including pricing and inventory information, associated with each UPC.
  • the computer interprets the UPC, looks up the price for each item, and keeps a running total of the purchase. Foir a chain of retail stores, each of the store platform computers are often linked to a central computer. This allows the data base of each store to be modified by changing only the date base of the central computer.
  • Pricing indicators In a store, merchandise offered for sale is typically displayed in some way, usually by placing the merchandise on a shelf. Plastic or paper pricing indicators are commonly mounted in proximity to the merchandise to notify customers of its price. Pricing indicators often include information such as size, weight, unit price and other identifying information.
  • the computer's data base must be modified to reflect the price change. As soon as this change occurs, the new price will automatically be charged to customers at the check-out terminal. Second, the price indicator for each of the affected items must be changed. It is desirable to change the data base and the indicated price at the same time so that there are no discrepancies.
  • U.S. Pat. No. 4,002,886 to Ronald M. Sundelin dated Jan. 11, 1977 discloses an electronic price read out system in which preprinted price indicators are replaced by electronic price indicator units. The information displayed by these units can be changed at will by changing the electrical stimulus at the input of each unit.
  • Each of the electronic price indicator units is connected to the same computer that supplies prices to the POS terminals. This way the system assures that whenever the price of an item is changed in the computer's data base, both the price displayed and the price charged at the check-out terminal are automatically changed to the new price.
  • the Sundelin patent discloses that the computer is connected to the price indicator units using four conductors or wires. This feature makes the system difficult to implement as it requires wires to be routed throughout the store.
  • each unit is assigned a unique address. Correlation in the computer database between the price indicator unit address and the price to be displayed is achieved either by manually entering the information into the computer via its keyboard or by using a remote unit connected to the store computer, the keyboard of the computer that is capable of reading the address of the price indicator unit, and the UPC on the merchandise.
  • U.S. Pat. No. 4,766,295 to Malcolm H. Davis discloses a similar system; however, the store computer is connected to the price indicator units via an infra red communications link.
  • One disadvantage to the system disclosed in the Davis patent is that there is only a one way communication between the computer and the price indicator unit. That is, the system only allows for information to be transmitted from the computer to the price indicator unit.
  • the present invention provides an integrated pricing and advertising system for displaying current pricing information as well as advertising information on remote display terminals throughout a store.
  • the system has a store platform computer which provides a data base for pricing and advertising information within each store.
  • the store platform computer is connectable to a central computer which may be located off-site.
  • a plurality of point of sale (POS) terminals are linked to the store platform computer.
  • a plurality of electronic price information display tags are mounted throughout the store at various merchandise locations. Each display tag is battery powered and contains a transceiver for communication with the store platform computer. Communication between the store platform computer and the display tags is facilitated with an IR controller and an IR transceiver grid.
  • the IR transceiver grid is comprised of a plurality of individual transceivers placed throughout the store and it is optically linked to the transceivers resident in each of the electronic display tags.
  • the IR controller is a microcomputer-based terminal which is hardwired to both the store platform computer and the IR transceiver. The IR controller regulates the transmission and reception of data to and from the IR transceiver.
  • a portable terminal which is coupled to and can communicate with both the store platform computer and the electronic display tags is used to initialize display tag addresses. Included in the system are portable electronic display terminals with transceivers for communication with the store platform computer as well as display terminals that are hard wired to the IR transceiver.
  • the IR transceivers and the display tags are both individually addressable.
  • the IR transceivers or transceivers actually communicating with the display tags are addressed and transmit IR signals.
  • the display tags are configured to have a low gain standby mode and to switch to a high gain mode only when receiving IR signals, battery power for the display tags is conserved because only those display tags in the vicinity of the display tag to be addressed are switched to the power consuming, high gain mode.
  • two-way communication is established between the IR transceiver and the display tags so that the price data to be displayed by the display tags or an error check signal can be transmitted back to the IR controller to verify that the correct price data has been received by the display tag.

  • FIG. 3 is a schematic diagram of the IR controller, the IR transceiver grid, and the display tags; and FIG. 4 is a diagram of the message words transmitted between the IR controller and the display tags via the IR transceiver grid and the timing of such message words.
  • the store platform computer 10 provides a data base for all of the merchandise in the store.
  • the data base associates each item of merchandise with, among other things, the price of the item, and its (UPC) .
  • the store platform computer 10 is electrically connected to a plurality of point of sale (POS) terminals 12.
  • POS terminals are used to sense the UPC code on the items of merchan ⁇ dise, the UPC is interpreted by the POS terminal, and the UPC is sent to the store platform computer.
  • the data base in the store platform computer is referenced and the price associated with that particular UPC code is found and added to the running total of the purchase.
  • Price changes may be made in the data base at the store platform level; however, if the store platform computer is linked to another computer 14, one that serves as a central computer to a plurality of store platform computers, then price changes can be made at the central computer 14 and downloaded to each of the store platform computers 10.
  • the store platform computer also supplies data, in addition to providing data to the POS terminals, to a plurality of electronic display tags 16.
  • Display tags are used to convey pricing and other information about the particular item of merchandise the tag is associated with.
  • the display tags have the ability to store and then display information as a function of time. This ability allows price changes and other information to be displayed at a specific time and day without the need of communication with the tag at that specific time and day. This feature makes it possible for relatively instantaneous changes to all tags even though the system may have slow data communication rates.
  • power consumption of the tag is reduced since the largest power consumption exists when communication is taking place. One communication can program many changes in displayed information.
  • the information display system is integrated into the POS system by adding to the described POS system an IR controller as well as communications software both within the IR controller and the Store Platform computer.
  • the assembly language listing of the application code for the IR controller is attached under Appendix A and is hereby incorporated by reference.
  • the application program listing for the store platform computer is attached in Appendix B and is hereby incorporated by reference.
  • merchandise is placed on shelving 18 within the store and an electronic display tag is mounted on the shelf adjacent to each item of merchandise.
  • Each of the display tags may indicate various information relating to that particular item, such as the total cost, the cost per unit, the size or weight, etc.
  • Each of the electronic display tags contain an infra-red (IR) emitter for transmitting data and an IR sensor for receiving data.
  • IR infra-red
  • Each tag is uniquely identified by a binary address which is stored in random access memory RAM within the tag. This allows the address of the tag to be changed from time to time.
  • the electronic display tags are powered by a battery which operates the IR sensor in two modes. To reduce battery power consumption, the IR sensor amplifier is normally maintained in a low gain mode. When an IR signal is radiated toward the display tag, the IR sensor amplifier is switched to a high gain mode. By way of example, a high gain mode could be enabled or energized periodically to detect when an IR signal is present. If during an enabled period an IR signal is received, the IR sensor receiver is maintained in the high gain mode for a predetermined time period after the IR> signal ceases.
  • the electronic display tags communicate with a grid of IR transceivers 18 which, in an exemplary embodiment, are housed in the ceiling of the store. Only one of the IR transceivers is illustrated in FIG. 1.
  • the IR transceiver grid is made of an array of IR emitters and IR sensors 20 which are positioned at selected positions in the ceiling 19. It is not necessary to have a direct line of sight between the transceivers in the display tags and the transceivers in the ceiling since infrared signals may be reflected.
  • the number and location of the IR emitters and IR sensors in the IR transceiver grid depends on the number and location of the electronic display tags.
  • each IR transceiver 18 communicates with only a relatively small number of the total number of display tags 16 in the store. For example, if the store has 20,000 display tags, there could be 300 IR transceivers each communicating with about 50 to 75 display tags in its vicinity, the grid of IR transceivers being spaced apart two to four feet and overlapping somewhat the display tags with which they communicate.
  • the IR transceiver grid 18 is connected to the IR controller 22 which is in turn connected to the store platform computer 10.
  • the IR controller is a microcomputer-cased terminal that controls transmission from and reception of the IR transceiver grid.
  • the IR controller provides two basic functions. It converts parallel binary data into a serial stream of coded data for transmission from the IR transceivers.
  • the IR controller also converts coded serial data from the IR transceivers to parallel binary data.
  • the IR transceiver grid and electronic display tags are also capable of communicating with the hand held unit 24.
  • the hand held unit has an IR emitter and an IR sensor for communicating with other transceivers, a keypad for entering information, and scanning means for sensing and interpreting UPC markings on items of merchandise.
  • the hand held tag is used by an operator to initialize the electronic display tag so that the tag will display information pertaining to only that item of merchandise. First, the clerk uses the hand held unit to scan the UPC marking on the new item.
  • the UPC is then transmitted from the hand held unit to the store platform computer via the IR link between the hand held unit and the applicable IR transceiver.
  • the computer processes the UPC and assigns a product identification code to that item and the product identification code is transmitted back to the hand held unit via the IR link.
  • the operator then uses the hand held unit to inject the code into the electronic display tag. This is done optically via the wireless link between the IR emitter in the hand held unit and the IR sensor in the electronic display tag. In order to avoid miscommunication with a nearby display tag, the hand held unit must be held in close proximity to the display tag. The hand held unit then advises the store platform computer that the download is complete. Once complete, the tag is able to communicate to the store platform computer via its own transceiver.
  • additional information may be supplied to the data base.
  • the operator may use the hand held unit to tell the store platform computer where the item is located in the store.
  • the information supplied to the electronic display tag remains intact until it is changed on command by the store platform computer. For example, when the price of an item changes, the price change is entered into the store platform computer by an operator. Once the data base changes, the new price is available for the POS terminals. The operator will also instruct the store platform computer to update the price on the electronic display tag which is associated with that item. The store platform computer will send a message containing the price change over the IR transceiver addressed to the appropriate electronic display tags.
  • IR transceivers 18 are each assigned unique addresses and display tags 16 are each assigned unique addresses.
  • a particular IR transceiver will only transmit an IR signal to the display tags in its vicinity if it first receives a message word having an address that matches the address assigned to the IR transceiver.
  • fewer than all the IR transceivers usually transmit IR signals and only those display tags in the vicinity of such IR transceivers are switched to the high gain mode. As a result, battery power is conserved.
  • only the display tag assigned the address that matches the address of the IR signal responds to the display tag data carrier by such IR signal.
  • display tags 16 transmit to and receive IR signals from IR transceivers 18 in their vicinity.
  • Some price tags may receive IR signals from more than one transceiver, but, nevertheless, in the preferred embodiment, fewer than all of them to conserve battery power.
  • An instruction field determines what such display tag does with the display tag data field, e.g. changes the displayed price.
  • Two-way IR transmission takes place between the IR transceivers and the display tags. Message words having the display tag address and the display tag data are transmitted from the IR transceivers to the display tags, and signals to verify receipt of correct display tag data are transmitted from the display tags to the IR transceivers.
  • the verifying signal is a simple data-valid signal comprising a unique code word of several binary bits, which is sent by a display tag when the display tag data it receives satisfies a parity check.
  • the verifying signal could comprise a retransmission of the display tag data to the IR transceiver for comparison with the data it had sent. In either case, the display tag data is retransmitted by the controller if the verifying signal is not received by the IR transceiver.
  • the controller transmits an acquisition signal to all the IR transceivers at a time Tl.
  • the acquisition signal has an IR transceiver address field and a check sum field that carries parity bits to verify that the correct acquisition signal has been received by the IR transceivers.
  • the addressed IR transceiver transmits a send data signal to the controller if parity checks.
  • a display tag signal is transmitted by the controller. Only the addressed IR transceiver, i.e. the transceiver that transmitted the send data signal, responds to the display tag signal.
  • the display tag signal has a display tag address field, a check sum field that carries parity bits to verify that the correct display tag address has been received, a display tag instruction field that defines the function to be performed, a display tag data field that defines the price or other data to be displayed by the tag, and a check sum field that carries parity bits to verify that the correct display tag data has been received.
  • the instruction field could identify the type of data in the display tag data field and how it is to be used by the display tag.
  • the addressed IR transceiver transmits a data valid signal to the controller if parity checks.
  • the addressed transceiver transmits to the display tags in its vicinity an IR signal modulated with the display tag signal.
  • the addressed display tag transmits a data valid signal to the IR transceiver.
