BACKGROUND OF INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a device for collecting and maintaining data on consumable goods in a list. More particularly, the present invention relates to a device for collecting, storing and outputting a list of consumer goods, (presumably which the user intends to purchase upon outputting said list). Additionally, said list can be cross referenced with the databases of assorted stores in an effort to assemble a list based on price, store location, availability and other potential criteria. Note: the present invention does not track inventories of the consumer goods.  
         [0003]     2. Description of the Prior Art  
         [0004]     In a hectic world, it is becoming more difficult for households to establish a cognizant list of consumable goods needed by the individual household members. Additionally, many consumers do not want to maintain intensive databases and inventory control systems in their personal homes. A simple, intuitive device which does the listing, sorting and comparison shopping for the residential consumer, or small business purchasing manager, is what is needed.  
         [0005]     U.S. Pat. No. 6,616,049 discloses a system which creates a shopping list for the purpose of generating sales incentives (i.e. coupons) for items on the list. This may be less than appealing since many consumers may not wish to be marketed to in this fashion. Additionally, this system does not comparison shop or sort shopping list data.  
         [0006]     U.S. Pat. No. 6,386,450 discloses a system which organizes a consumer&#39;s movement through a store providing distance and direction to items in that store and the list is maintained on a data card. While useful, this hand held device will be less convenient than a list of goods presorted in the order they appear within the store.  
         [0007]     Additionally, people carry many hand held devices as it is and using this one and using a cell phone at the same time, for example, may be cumbersome.  
         [0008]     U.S. Pat. No. 6,131,812 discloses a system which monitors the inventory of consumer goods by means of scanning, quantity entry and the use of a scale. It additionally provides medical interaction alerts. However, this system requires significant user input; has the potential of user error, the potential of health affecting risks where medications are concerned; and requires users to maintain and manage a significant database of household inventories, weights, calories, preferences and other data to achieve full functionality.  
         [0009]     U.S. Pat. No. 5,870,716 discloses a system which tracks user purchasing trends via store input and generates a shopping list based on an estimated consumption interval, However people&#39;s tastes change over time and most may like a bit more control over their shopping list. Additionally, vacations, holidays, guests, etc. may throw off the system as consumption changes due to these variables.  
         [0010]     U.S. Pat. No. 5,884,281 discloses a system which creates an electronic shopping list from stored or manual data specifically without a scanner. The list may be transmitted for fulfillment, but there is no comparison shopping feature or multiple user options.  
         [0011]     U.S. Pat. Nos. 5,335,509 and 5,487,276 disclose systems which monitor the expiration dates of various products and provide an alert when a product is close to its expiration date. However, these systems require significant user input; and require users to maintain and manage a significant database of household inventories and they do not comparison shop.  
         [0012]     None of the above inventions and patents, taken either singly, or in combination, is seen to describe the present invention as claimed.  
         [0013]     Accordingly, there is a need for a device which can efficiently and simply maintain a record of consumable goods which need to be purchased in the near future, without the complexities of micro-managing a home inventory system, recording weights and other units of measure, medical interactions, quantities, consumption rates and other data. Additionally, this system should be able to advise the retail store of imminent demand so that the retailer can ensure sufficient inventory to supply the imminent demand of the cumulative users&#39; shopping lists.  
       SUMMARY OF THE INVENTION  
       [0014]     The present invention relates to a hand held, free standing or mountable device, which can be surface mounted or inset in various locations, incorporating a scanner, display system, output device and potentially, supplemental input devices. The system includes a microprocessor with memory means for storing information about consumer goods. Various means are associated with the microprocessor for inputting information regarding the consumer goods. The system computes and stores a shopping list, store name, retail price and location information. The information can be displayed in visual or audible form. A printer, modem or other communications device may also be provided for outputting the information.

         [0074]     Note: a manufactured supplemental input device  2  may consist of a configuration somewhere between that of the configuration shown in  FIG. 5  and  FIG. 6  and that of the configuration shown in  FIG. 9 . Additionally, some other elements may be substituted for the elements shown in  FIG. 9  for example: a keyboard might be substituted for the key pad  22 .  
         [0075]     The device  1  of the present invention generally includes a processor assembly  10 , an input/output (I/O) center  20 , a scanning mechanism typically a scanner  30 , a printer  40  and a communication device typically a modem  50 , which are integrated into the device  1 . The processor assembly  10  generally comprises a microprocessor  11  which will be programmed to perform the functions described herein.  
         [0076]     The I/O center  20 , as shown in  FIG. 7 , generally comprises a visual display  21 , a keypad  22  and a light pen  31 . Additional elements can be added to this general configuration as described herein.  
         [0077]     The visual display  21  which is preferably one or two lines of LED text characters similar to the type commonly used with typical calculators. The visual display  21  displays text which prompts the user and also provides output requested by the user. Alternatively, the visual display  21  could be a touch screen display. In this case, the keypad  22  may not be required.  
         [0078]     The printer  40  is a simple small printer of the type often used with printing calculators which allows the user to print shopping list  3 .  
         [0079]     The keypad  22  allows the user to input information into the device  1 . The keypad  22  can be provided in various configurations including keys with alpha-numeric characters similar to a commonly used telephone pad, and command keys similar to a commonly used microwave. The keypad  22  is preferably fixed in the device. Alternatively, the keypad  22  can be connected to the device  1  through a cord (not shown) or can be provided with remote access capabilities similar to a television remote control.  
         [0080]     The scanner  30  is preferably connected to the device  1  internally. The scanner  30  is preferably used to read UPC bar codes, EAN codes, JAN codes, PDF  417  or other symbols used in the labeling of consumer goods. Alternatively, a light pen  31  could be connected to the device  1  through a cord  32 . Holding clip  33  is provided to hold the light pen  31 . The light pen  31  is alternatively used to read UPC bar codes or other symbols used in the labeling of consumer goods. In this case, the scanner  30  may not be required.  
         [0081]     The device  1  is normally powered by a power source  80  consisting of an electrical plug  81  or the host appliance. It is additionally preferred that a back-up battery  82  be supplied to maintain data during power interruptions.  
         [0082]     As shown in  FIG. 7 , the visual display  21  shows text messages including the date, time and current quantity of items on the list. The keypad  22  allows the user to select various options. These function selection techniques will be familiar to individuals who have used household appliances.  
         [0083]     It is contemplated that the principal means of entering data about the consumer goods will be the use of the UPC bar code and other similar symbols. This data will generally be entered by moving the bar code in front of the scanner  30  or sliding the light pen  31  across the bar code. Alternatively, the product number may be entered into the device via the keypad  22 . In most instances, the UPC or other codes will correlate to information about the product contained in the microprocessor  11  or a remote database accessed via the modem  50 .  
         [0084]     In the instance where a UPC or other code is not recognized by the device, the user will be prompted to instruct the device to ‘look up’ the item in databases maintained by the manufacturer of device  1  or one or more retail stores, via the modem  50  or to enter text for the product to then be stored, within the microprocessor  11 , with the unrecognized bar code. This data may be entered by the user through the keypad  22  as text (example: “onion soup”) in a fashion similar to entering text into a cell phone. In the instance where a UPC or other code is not provided, or it has been discarded or lost, the data may be entered by the user through the keypad  22  as text (example: “lettuce”).  
         [0085]     When an item is entered via UPC or other code or text the microprocessor will check the current list for duplicates and then add the product to the shopping list. Each time a product is found by the system to be ‘already on the list’ the user will be prompted to confirm the duplication of that product on the list.  
         [0086]     The processor assembly  10  with microprocessor  11  is preferably about the size of a hand held calculator. The microprocessor  11  will have sufficient memory capacity to store hundreds of thousands of product records. Each product record may include, but is not limited to, the UPC or other codes, item name, brand name, purchase date, price, a store code and aisle number. The processor assembly  10  with microprocessor  11  is also able to be programmed with the decoding logic necessary for reading UPC symbol codes and other similar symbols.  
         [0087]     As can be seen from the above description, the present device will provide a user with a readily available means of adding an item to a shopping list  3  (presumably just before discarding the item or its packaging) at a convenient location (the refrigerator, freezer or near the trash can or telephone). For instance, the user may input items to the list as those items are discarded. Also, when a purchased item is unwrapped before it is normally used (example: a secondary overwrap), the wrapper can be scanned and discarded before the product is actually used.  
         [0088]     To find out the items on the shopping list  3 , the user simply hits the up or down arrow keys on the keypad  22  to scroll through the list. To print the shopping list  3  the user hits print. Many other assorted features may apply.  
         [0089]     The modem  50  may be used to send a text version of the shopping list  3  to a computer, cell phone, personal digital assistant, global positioning device or other electronic device capable of receiving and displaying electronic data. Additionally, the user could call the present invention via the modem  50  to download the shopping list  3  to their cell phone in the event that they forgot to print the shopping list  3 . The modem  50  may alternatively be replaced with or supplemented by an inferred data transmitter/receiver  73 , a remote control  74 , a wireless network transmitter  70 , a satellite link  71  or other transmission device.  
         [0090]     The modem  50  will also be used to download store specific information into the microprocessor  11 . This information can consist of a store number and aisle number associated with that specific store and pricing information. Additionally, the modem  50  could be used to contact two or more stores in the area to obtain pricing and aisle location information. The microprocessor  11  can then sort the item information by store name and price, creating two or more separate shopping lists  3 , one list for each store, placing the items on the list for the store having the lowest price. This feature can save the consumer thousands of dollars per year.  
         [0091]     Similarly, the device  1  could be configured in a more advanced version to comparison shop a product between multiple different brands of the same type of item, having different UPS codes, allowing the consumer to shop by store price comparison of the exact item and manufacturer brand price comparison between different brands of the same type of item.  
         [0092]     The microprocessor  11  can sort the products on the list by several other criteria. For example, a user could sort by aisle number or food category and print the shopping list  3  in that order to speed the selection of items in the store, or to help find a specific item in the store when the user is unsure of it&#39;s likely location. This is generally done automatically as shown in  FIG. 8 .  
         [0093]     The device could also maintain a list of continually purchased items as selected by the user. These items would no longer need to be scanned, and would always appear on the shopping list and be sorted by store, price and other criteria. For example, regular staples such as milk, eggs, cheese, bread, toilet paper, etc. could be left on the list indefinitely.  
         [0094]     As shown in  FIG. 9 , a supplemental input device  2  may be connected to the device  1  via the input/output port  52 . A supplemental input device  2  would likely include a scanner  30 , visual display  21  and keypad  22 . The supplemental input device  2  could be located in another room (bathroom, pantry, garage, bedroom, etc.) and feed user data entry back to the primary device  1  where shopping list creation and printing/transmitting occur. A residence could have any number of supplemental input devices  2 .  
         [0095]     The device  1  has inherent usefulness to disabled persons who are unable to write, and may simply scan the item into the system and print when ready to shop. Furthermore, the device could be configured in several forms to aid the disabled. The microphone  61  could be used in conjunction with voice recognition software to input data by a disabled person unable to use the scanner or keypad. Further, a visually impaired person may have the device  1  read the data and commands via text reading software and the speaker  60 . Brail signage  24  (not shown) can be implemented on the key pad  22  to complete this process. Additionally the device  1  could by linked to a TDI Device for further handicapped assistance.  
         [0096]     In addition to maintaining a shopping list  3 , incorporation of the present invention into an appliance surface  90 , or telephone  93  may permit the user to control some or all of the appliance or telephone features directly from the device  1 , or to control the device  1  from the appliance or telephone controls. In many instances, it may be best to integrate the controls of the device I into the design and construction of the controls for appliance or telephone.  
         [0097]     In addition to maintaining a shopping list  3 , the device can incorporate the features of a typical printing calculator and be used as such.  
         [0098]     In addition to maintaining a shopping list  3 , the device could incorporate the features of a typical telephone via use of the microphone  61 , speaker  60  and modem  50  and be used as such.  
         [0099]     In addition to maintaining a shopping list  3 , the device could incorporate the features of a recording device via use of the microphone  61 , speaker  60  and modem  50  and be used for voice mail, audio reminders or the like.  
         [0100]     In addition to the above, the device  1  can be used in a small business setting. Each employee can scan items as described herein. In this configuration, there would be a user code used by each employee or user, used to indicate what employee or user scanned the item, and a password to verify the identity of that employee or user. Multiple distinct shopping lists could then be created for each employee or user. The purchasing agent for the business could then assemble the shopping lists for comparison inquiry to the stores and finally review and purchase the needed items. Multiple distinct user lists could be used in the home setting as well, for example, college roommates with separate shopping lists.  
         [0101]     The device  1  can convey to the store or stores the shopping list  3  for the purpose of inventory control and marketing research. When the price comparison inquiry is done via the modem  50  to the retailer database, the retailer is advised of the user&#39;s intent to buy the given items in the near future. At this time the items on the previous shopping list are removed from the store&#39;s imminent demand list and the new items are added. The Retailer&#39;s software can then check the current inventory, subtract the total quantity of items inquired about (by multiple users of the device  1 ), and warn the retailer&#39;s purchasing department of pending shortages in inventory. Example: There are  91  inquiries into the price of item ZZZ over the last three days, store WWW has the best price, but only  43  of item ZZZ in stock, the retailer can order and receive more of item ZZZ before the imminent demand for item ZZZ exhausts the inventory and as a result the retailer looses out on up to  48  sales of item ZZZ.  
         [0102]     Additionally, the marketing data can allow the store to improve turnover of products. The inquiries data can help determine if an item has an excess inventory. In this event, excess inventory items can have the shelf space allocated to those items reduced to a level where it maintains imminent demand plus a margin, but does not over exceed ‘actual demand’ by occupying more shelf space than that necessary to meet the imminent demand plus a margin. This allows more shelf space for other items or for items with greater imminent demand that usually go out of stock because the imminent demand was underestimated by the retailer&#39;s purchasing department. This is useful since retailers may not be able to track this type of lost sale since the consumer will either select a second favorite item instead, or purchase the desired item at another store.  
         [0103]     The device  1  can further provide better communication between the retailer and the consumer as a direct line of communication exists because of the device  1 . The communication process defined herewith would allow the retailer to conduct marketing research by sending questions, polls or quarries to the consumer directly via the device  1  and receiving the response directly in return.  
         [0104]     Furthermore, the shopping list  3  can be forwarded in digital form to a fulfillment house for direct delivery or to a web site for remote downloading (perhaps just before leaving work and going to the store).
