     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention is an electronic grocery lister, having three preferred embodiments. 
     FIG. 1 is a perspective view of the portable first embodiment of the invention generally referred to as 10. At the top a liquid crystal display (LCD) 22 can be seen. This is where the user will see what he or she types in, will choose options off the menu, and will view and edit the grocery list. 
     Directly below the LCD 22 is an area which has a typed category list 4. This is a list of two hundred most commonly bought items. This list may be changed by the user to fit needs. To the left of each item is a corresponding item code. When the user wishes to enter one of these items quickly, all he or she has to do is press the code and that item will be entered on the database and displayed on LCD 22. Examples of such items could be milk, carrots, or toilet paper. 
     On the lower part of the invention a long strip can be seen. This is a small solar panel 6. The purpose of the solar panel is to recharge the AA batteries 8 (see FIG. 3). The solar panel 6 is preferably of equal width with the LCD. Below the solar panel is a numeric/letter keypad 44, up and down scroll buttons 12, four category buttons 14, an enter button 15, a delete button 16 and two indicator lights, one green 18 and one red 20. The category buttons 14 allow the user to jump to different categories in the database list displayed on LCD 22. The enter button 15 is used to enter data into the computer. The database list starts out as the same list found on the printed category list 4. This list may be edited by the user if he or she wishes. The delete button 16 is used to delete highlighted items or to backspace over what has been typed. The green indicator light 18 acts as a reminder that a personal message awaits. The red indicator light 20 signifies that the user&#39;s predetermined time to go shopping has arrived. 
     FIG. 2 shows the perspective view of the non-portable second embodiment of the invention generally referred to as 10&#39;. As it does not need to be portable, the second embodiment may be larger and heavier than the first embodiment, and has a larger LCD 22. The only difference between this version of the invention and the portable version, other than size, is that this version has a printer 52 and a print button 17. The whole of the printer 52 is inside the invention. The printer slot 24, which has been designed to accept index or note cards 26, is located at the top of the invention. The slot 24 is slightly larger than card 26 and is a quarter inch deeper, allowing the printer 52 to be able to print anywhere on the surface of the card 26. The print button 17 is to the right of the enter button 15. 
     FIG. 3 is a rear elevational view of either embodiment of the invention. The four round objects 28 which can be seen may be either hook and loop fastener tabs or magnets. Also the area where the batteries 8 are located can be seen. The projection tab 32 which is to be used to open the battery cover 30 is also visible. Batteries 8 can be seen behind the battery cover 30. 
     FIG. 4 shows a block wiring diagram of the invention. Whenever there is enough light falling on the solar panel 6 the invention will resume operation where last left off. If there is not enough light, the invention will drop into a hibernation mode. The state the invention is in at any given time will be dependent upon whether there is enough amperage coming from the solar panel 6 to charge the batteries 8. The inability of the user to use the invention when there is not enough amperage will not be an onus. This is because the only time there will not be enough light for the invention to function is when there is also not enough light for the user to see. When the invention goes into a hibernation mode, the information in the invention at that time will be stored in a volatile storage device 34 which is random access memory (RAM). 
     Additionally, the invention may be turned off via the on/off switch 36. Turning the invention off will clear the volatile storage device 34 and correspondingly eliminate all stored data. Stored in the non-volatile storage device 38 will be the standard data sets. This data can be modified by the user. The non-volatile storage device 38 will also contain any help menus and other information needed by the command set 40. The command set 40 is the program by which the invention will function. The command set 40 will also need to use the volatile storage device 34 in conjunction with the central processing unit (CPU) 42 in order to function. 
     The user will control the invention through the buttons 12, 14, 17, as well as through the use of the key pad 44. The commands will travel from the buttons and key pad 44 to the command set 40 via the key pad interface controller 46 and then through the CPU 42. An example of this would be where the user wishes to print his or her grocery list. In order to do this the user would press the print button 17. This would tell the command set 40 to transmit a copy of the list 48 from the volatile storage device 34 to the printer interface 50, which would then spool the information correctly to the printer 52. 
     Also visible in FIG. 4 is the LCD display brightness display dial 54. This is a variable resistor. To the right of the CPU 42 is the power source 56. This is the pair of AA batteries 8. Below the power source 56 is a secondary power source 58, which is a standard thumbnail battery. The purpose of this secondary power source is so that, when the primary power source 56 is replaced, everything stored in the invention does not have to be lost. Attached to the power source is the solar panel 6 which continuously charges the power source 56. The power source 56 charges the secondary power source 58. 
     In a third embodiment of the invention (not shown in the drawings) a fax modem is included to allow the grocery lister to send and receive messages. This will enable users of the invention to shop in the comfort of their own home, by just entering the desired items, or retrieving a list that the invention has compiled, and dialing their favorite store to send in their grocery list, provided that the store itself is on-line with the necessary computer hardware and software. In using the third embodiment of the invention, an user would perform the following steps: 
     1. Enter desired items or retrieve list. 
     2. Dial the telephone facsimile number of a store that has on-line shopping. 
     3. Transmit list to the store, and wait for a list check by the store&#39;s computer. 
     4. Enter second choices if the list check shows that some items on the list are out of stock, and whether the user wants to pick up items or have them delivered. 
     5. After the total bill from the store&#39;s computer is displayed on the invention&#39;s LCD, the user enters a credit card number and expiration date to make payment. 
     6. After the estimated time that the items will be ready for pick up or delivery is calculated by the store&#39;s computer and displayed on the invention&#39;s LCD, the user indicates what time they will pick up or accept delivery of the items. 
     7. User shows identification to store&#39;s personnel when picking up items at store or accepting delivery at home. 
     It is to be understood that the present invention is not limited to the sole embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
