Description:
BACKGROUND OF THE INVENTION 
     This invention relates to a compact portable, handheld calculator/timepiece, that is capable of storing, retrieving, searching, editing, deleting and outputting of information pertaining to the purchasing of, and collecting of audio and audiovisual media. The audio and audiovisual media comprising of, but not limited to; audio cassette tapes, digital audio tapes, records, compact discs, laser discs, video tapes, 8 mm film, 16 mm film etc.. 
     Many people have large collections of audio media, and/or of audiovisual media, to which they regularly acquire new additions. To catalog and to ensure that no duplicate acquisition is made, can be a time consuming and difficult task if manually done. 
     Currently people who regularly purchase audio and audiovisual media have no portable automated means to keep track of their existing purchased media. It has been observed that the more dedicated audiophiles keep track of their existing collection by means of index cards, similar to the system used in a public library. This is a manual system whereby the audiophile keeps track of their acquisitions by writing relevant details on a card, which is then added to an existing library of cards. Whenever the user of such a system goes on a buying spree, then the complete card library has to be ported to the record store. This is naturally cumbersome and difficult to maintain. 
     The present invention provides the means for the user to electronically translate the above described index-card system into a portable and easy to use electronic device. Furthermore the present invention provides the means to the user to integrate the Portable Audio/AudioVisual Media Tracking Device with a larger user database that resides on an external computer, such as a personal computer. 
     OBJECTIVES OF THE PRESENT INVENTION 
     Accordingly it is the objective of the present invention to provide a portable electronic calculator timepiece with the facilities for tracking a variety of audio and audiovisual media, consisting of media description data and related purchase data. 
     The media description data consists of, but is not limited to; the title of the recording; recording studio&#39;s name; type of media (compact disc, tape, video cassette tape etc.). This is discussed later in more detail. Henceforth, the media description data will be referred to as the recorded album. 
     The purchase data consists of, but is not limited to; the purchase price; place of purchase and date of purchase. 
     It is a further objective of the present invention to provide the means of inputting, storing, editing, retrieving, searching, deleting and outputting of the said recorded album description and purchase data. 
     It is a further objective of the present invention to provide the means of inputting and tracking purchased recorded albums by a variety of pertinent data. For example a collector of classical music recordings may want to track purchases by the composer&#39;s name, as well as by the performing artist and orchestra. 
     It is a further objective of the present invention to provide the means of inputting and tracking purchased recorded albums, such that the type of recorded album (CD, tape, movie reel etc.) is distinguishable. For example the user may want to distinguish between the cassette tapes and compact discs in his collection. 
     It is a further objective of the present invention to provide the means of inputting and tracking the purchased recorded album by means of any audio and audiovisual industry code standards. For example tracking audio recorded albums by means of the Consumer Clarification Code developed by the Society of Professional Audio Recording Studios; the SPARS code. 
     It is a further objective of the present invention to provide the means of inputting and tracking purchased recorded albums by means of the recording studio&#39;s name. In the audio recording world, this is the Record Label Name, for example Deutsche Grammophon. In the audiovisual media world this is the Film Studio&#39;s Name, for example MCA. 
     It is a further objective of the present invention to provide the means of inputting and tracking purchased recorded albums by means of any code that the said recording studio may have devised. This is similar to the ISBN number in the publishing world. Each recording studio usually has its own unique item code, which is usually an internal database inventory code. 
     It is a further objective of the present invention to provide the means of inputting and tracking purchased recorded albums by subcategory. For audio recorded albums this is the type of music, for example, Classical, Jazz, Pop, Heavy Metal etc. For audiovisual recorded albums this the genre of film, for example, Comedy, Science Fiction, Horror etc. 
     It is a further objective of the present invention to provide the means for bi-directionally transmitting stored information between the present invention and an external computer, and unidirectional to a computer printing device. 
     Other objectives and further scope of applicability will become apparent from the detailed description given hereinafter. It should be understood that the detailed description and specific examples, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those versed in the art from this detailed description.

     DETAILED DESCRIPTION OF THE INVENTION 
     The current invention uses, by way of example only, an embodiment that tracks user audio recorded albums description data and purchase data. To those versed in the art, it will become apparent from the following description, that the said description can as easily apply to a device that tracks audiovisual recorded albums description and purchase data, or to a device that tracks both types of recorded albums. 
     FIG. 1 is a block diagram of a principal circuit for implementing the present invention. The circuit comprises of a circuit oscillator 1, a frequency divider 2, a time keeping counter with calendar functions 3, an alarm coincidence detection circuit 4, clock and calendar alarm memory 5, Program Memory 6, a controller CPU 7, random access memory RAM 8, a keypad interface circuit 9, a keypad unit 13, a display interface circuit 10, a display unit 14, a communications interface circuit 11, a sound generating circuit 12, a speaker 15, a bar code reader interface circuit 16 and a bar code reader unit 17. 
     The oscillator circuit 1 is coupled to a crystal oscillator, that is not shown, for generating a time base signal in the form of clock pulses of the crystal oscillator&#39;s frequency (for example 32.768 Khz ). The frequency divider 2 is responsive to the clock pulses for frequency dividing of the said frequency to a specific frequency that is applied to the controller CPU 7 and lastly divided to 1 Hz, which is applied to the time keeping counter 3. 
     The counter 3 provides the present invention with all time and calendar functionality. The 1 Hz frequency generated from the frequency divider 2, generates a signal to maintain the current time in seconds, minutes and hours, as well as current calendar data such as the day of the month and year. This horological data is available to the controller CPU 7 and to the display interface circuit 12. 
     The clock and calendar alarm circuit 5 contains the user defined alarm time and date information, which is entered into the present invention by means of the keypad 13. The clock and calendar alarm circuit 5 has an associated coincidence detection circuit 4, which determines the equivalency between the alarm time and date stored in the clock and calendar alarm 5, and the current time and date as maintained in the clock and calendar update circuit 3. When an alarm equivalency is detected, the coincidence detection circuit 4 generates a clock and calendar alarm active signal, which is transmitted to the CPU 7. 
     Program Memory 6 contains all programs that the CPU 7 uses to interface with all of the present invention&#39;s circuit modules 1 through 6 and 8 through 17. Program Memory 6 also contains all the programs required to enter, store, retrieve, edit and delete all data in RAM 8. Program Memory 6 also contains programs to send and receive recorded album data between the present invention and a remote computer, via the communications interface 11. Furthermore Program Memory 6 also contains all non-volatile system messages, (for example, functional menus and error messages ), that are to be displayed via the display interface circuit 10 and the display unit 14. 
     RAM 8 stores all the dynamic user recorded albums description data and related purchase data, as well as any other user dynamic data. 
     The keypad interface circuit 9 receives an output from a user selected key on the keypad 13, delivers its corresponding coded key output, senses the meaning of the key output and develops an output representative of its results, that is interpreted by the CPU 7. 
     The display interface 10 controls the display unit 14 by means of data received from the CPU 7. The display unit 14 could be any form of display that present technology avails, for example LCD or LED displays. Because of the relatively low power consumption of the present day LCD technology, this said form of display unit is used by way of preference in the embodiment of the present invention. 
     The communications interface 11 allows bi-directional transfer of information between the present invention and a remote computer (not shown). This said circuit establishes and breaks the communications link and maintains the integrity of the data transferred between the present invention and a remote computer. The technology used to implement the said circuit could be anything that current technology avails, for example RS-232C or GPIB interface protocols. The communication&#39;s interface 11 also facilitates the unidirectional transfer of data between the present invention&#39;s preferred embodiment and a remote printer (not shown). 
     The bar code interface circuit 16 allows the user to input data in the form of a bar code, provided that a bar code reader 17 is connected to the present invention. This allows some data to be automatically scanned into the present invention, instead of the user having to enter it by means of the keypad 13. 
     FIG. 2 is a plan view showing the perspective of the illustrated embodiment, which includes the keypad 13, the display panel 14, the communications interface 11, the speaker 15, the bar code interface 16 and in addition, a mode selector switch 18. The mode selector switch 18 enables the user to select either one of three modes; the OFF mode which disables all of the present invention&#39;s functionality, except for any set alarm conditions and stored information in the invention&#39;s memory; the MEDIA mode, which enables the user to manipulate recorded albums&#39; information with the said invention; and lastly the CALC mode, which enables the user to use the present invention as a normal calculator. 
     Tables 1 and 2 enumerate the titles of the respective keys on the keypad 13.

     Before describing in detail FIGS. 3a through 3p, a note needs to be made about the user interaction with the preferred embodiment of the invention. The present invention interacts with the user by means of function keys (see FIG. 2, tables 1 and 2) on the keypad 13 and system generated menus (FIGS. 3a through 3p) on the display 14. 
     Furthermore the system menus are divided into primary and secondary menus. The primary menus (FIGS. 3a through 3g) appear on the display 14 after the user has selected a function key on the keypad 13. The secondary menus appear on the display 14 (FIGS. 3h through 3p) in response to the user selecting an item on the primary menu and consequently allow the user to enter/select related data in the invention. Not all of the primary and secondary menus are illustrated. This is because many menus are similar and consequently in the Detailed Description, reference is made to similar menu diagrams, rather than fully describe all of the possible system menus. 
     It is possible to expand the number of function keys on the keypad 13 instead of using the system menus. The preferred embodiment of the invention uses system menus by way of illustration only. Additional function keys could as easily be used by the present invention to interface between the user and the invention. 
     FIGS. 3a through 3p illustrate the display 14 when a menu function key of the present invention is selected on the keypad 13; ENTRY, MODIFY, DELETE, SEARCH, SEND, RECEIVE and ALARM. The visible display 14 is divided into 2 lines. The top most line 19 illustrates the type of function key selected. For example if the ENTRY key is selected, then the message `** Enter **` is displayed on the top line 19 (see FIG. 3a). The bottom line 21 and 21 illustrate a menu of available selections for the function defined on the top line 19. For example in FIG. 3a, the user is able to Enter data into the invention by; 
     1) Composition 
     2) Performer 
     3) Record Company 
     4) Media Type 
     5) Purchase 
     6) Gift 
     7) All. 
     Only a single line of a menu&#39;s available selection is displayed in the present invention, namely line 20. The user has to use the scroll keys, NEXT or PRVS on the keypad 13 to access the hidden selections, which are illustrated by means of a broken line in FIGS. 3a through 3p (line 21). The NEXT key allows the user to scroll forward and the PRVS key enables the user to scroll backwards. For example, in FIG. 3a, if the user presses the NEXT key twice, the display 14, bottom line 20 would contain `3) Performer`. If the user now presses the PRVS key once, the display 14, bottom line 20 would contain `2) Composition`. To execute a currently displayed menu function the user presses the ENTER key on the keypad 13. To cancel a currently displayed menu function, the user presses the CLEAR key on the keypad 13. Throughout these scrolling actions the display 14, top line 19 remains static and unchanged--for example in FIG. 3a, the display 14 top line 19 would continuously display `** Enter ** ` whilst the user scrolled through the available menu selections, displayed in the bottom line 20. As mentioned previously the following detailed description applies to audio recorded albums, by way of example only. Reference is also made to equivalences in audiovisual recorded albums, but the primary description of the current invention&#39;s embodiment is devoted to audio recorded albums. 
     A note needs to be made about the data structure of an audio recording, e.g. a CD. Each recorded album is uniquely identified by its Record Co. data (see FIG. 3j). The recorded album can consist of one or more tracks of different compositions, which may or may not have the same performers. For example, a CD can have both Beethoven&#39;s 4th Symphony and Brahms&#39; 4th Symphony, or a tape can have a unique collection of songs by the Beatles and the Rolling Stones. Consequently the present invention provides the means to distinguish between various compositions and its performers on the same recorded album, if the user wants to track these compositions separately. Quite frequently the same composition appears on different recordings. For example, Beethoven&#39;s 5th Symphony has been recorded on the CBS label on many different CDs. For example CBS MT-32010 is with Bernstein conducting the New York Philharmonic and CBS MT-35892 is with Mehta conducting the New York Philharmonic. To an audiophile the ability to distinguish between these two recordings, of the same composition, is important. 
     FIG. 3a illustrates the display 14 when the ENTRY function key is selected on the keypad 13. Selecting this function allows the user to enter into the invention new recorded albums&#39; description data and related purchase data, which is stored in RAM 8. For example, if the user has bought a new CD and wants to enter it into the invention, then this said function key is selected. Note that the mode selector switch 18 needs to be in the MEDIA position. The user is able to enter the recorded albums&#39; data under various categories--the primary menu options, which are listed in the scroll display, lines 20 and 21. 
     The ENTRY function primary menu item `1) Record Co.` allows the user to enter a new recorded album by Record Company. The Record Company is the company that produced and recorded the recorded album. This is part of the primary access key to the data stored in RAM 8. To select this option, the user presses the ENTER key whilst the Record Co. menu item is displayed on the display 14 bottom line 20, or the user can simply select the number `1` (one) on the keypad 13. Once the user has selected this menu item, a secondary menu appears on the display 14, the Enter Record Co. menu FIG. 3j, which is described in detail later. The Record Co. recorded album&#39;s description data is a repeating item. For example, the user may elect to enter consecutively, multiple CDs into the invention. 
     The ENTRY function primary menu item `2) Composition` allows the user to enter a new composition for a given recorded album. A composition may be a symphony, a concerto etc. in the Classical music category; or it may be a song in the Jazz and Pop music categories. To select this option, the user presses the ENTER key whilst the Composition menu item is displayed on the display 14 bottom line 20, or the user can simply select the number `2` (two) on the keypad 13. Once the user has selected this menu item, a secondary menu appears on the display 14, the Enter Composition menu FIG. 3h, which is described in detail later. The Composition recorded album&#39;s description data is a repeating item. For example, on a given CD there can be multiple Compositions. Note that if the user had not previously defined a unique CD, by means of the Record Co. primary menu option, then before the secondary Enter Composition menu appears on the display 14, the current invention prompts the user for this data by displaying the message `** ERROR: no album selected **`, and then displays the Enter Record Co. secondary menu (FIG. 3j). The equivalent Composition data for an audiovisual recorded album would be Film, TV Serial etc. 
     The ENTRY function primary menu item `3) Performer` allows the user to enter a new performer for a given recorded album. A performer may be a conductor, or an orchestra, or an opera singer, or a pianist etc. in the Classical music category; it may be a singer, or a saxophonist etc. in the Jazz and Pop music categories. To select this option, the user presses the ENTER key whilst the Performer menu item is displayed on the display 14 bottom line 20, or the user can simply select the number `3` (three) on the keypad 13. Once the user has selected this menu item, a secondary menu appears on the display 14, the Enter Performer menu FIG. 3i,  which is described in detail later. Note that if the user had not previously defined a unique CD, then before the secondary Enter Performer menu appears on the display 14, the current invention prompts the user for this data by displaying the message `** ERROR: no album selected **`, and then display the Enter Record Co. secondary menu. The Performer recorded album&#39;s description data is a repeating item. For example, on a given CD there can be multiple Performers. The equivalent data for an audiovisual recorded album would be Actor, Directors etc. 
     The ENTRY function primary menu item `4) Media Type` allows the user to enter a new recorded album into the present invention by recorded album&#39;s type, for example CDs, tapes or LP records etc.. To select this option, the user presses the ENTER key whilst the Media Type menu item is displayed on the display 14 bottom line 20, or the user can simply select the number `4` (four) on the keypad 13. Once the user has selected this menu item, a secondary menu appears on the display 14, the Enter Media Type menu FIG. 3k, which is described in detail later. This data is always directly associated with Record Co. description data and cannot exist without the associated Record Co. being defined by the user. Prior to the user entering the Media Type data, the present invention checks to see if it is associated with any Record Co. data. If no such association exists the present invention automatically prompts the user to enter the required data by displaying the message `** ERROR: no album selected **`, and then the Enter Record Co. secondary menu, FIG. 3j. The Media Type description data is a repeating item. For example, the user may elect to enter consecutively, multiple CDs into the invention. 
     The ENTRY function primary menu item `5) Purchase Data` allows the user to enter purchase description data into the present invention, for a recorded album that currently exists in RAM s. To select this option, the user presses the ENTER key whilst the Purchase Data menu item is displayed on the display 14 bottom line 20, or the user can simply select the number `5` (five) on the keypad 13. Once the user has selected this menu item, a secondary menu appears on the display 14, the Enter Purchase Data menu FIG. 31, which is described in detail later. This data is always directly associated with Record Co. description data and cannot exist without the associated Record co. being defined by the user. Prior to the user entering the Purchase Data, the present invention checks to see if it is associated with any Record Co. data. If no such association exists the present invention automatically prompts the user to enter the required data by displaying the message `** ERROR: no selected album **`, and then display the Enter Record Co. secondary menu. 
     The ENTRY function primary menu item `6) Gift` allows the user to label the recorded album that currently exists in RAM 8, as having been purchased as a gift and consequently is not part of the user&#39;s personal collection. To select this option, the user presses the ENTER key whilst the Gift menu item is displayed on the display 14 bottom line 20, or the user can simply select the number `6` (six) on the keypad 13. Once the user has selected this menu item, a secondary menu appears on the display 14, the Enter Gift menu FIG. 3m, which is described in detail later. This data is always directly associated with Record Co. description data and cannot exist without the associated Record Co. being defined by the user. Prior to the user entering the Gift data, the present invention checks to see if it is associated with any Record Co. data. If no such association exists the present invention automatically prompts the user to enter the required data by displaying the message `** ERROR: no selected album **`, and then display the Enter Record Co. secondary menu. 
     The ENTRY function primary menu item `7) All` allows the user to enter recorded albums&#39; data into RAM 8. This option differs from all of the previously described data entry menu items, such that the present invention automatically prompts the user for all data entry description data, rather than the user selecting the required data entry item from a menu. To select this option, the user presses the ENTER key whilst the All menu item is displayed on the display 14 bottom line 20, or the user can simply select the number `7` (seven) on the keypad 13. Once the user has selected this menu item, the invention first prompts the user for Record Co. data and waits for the user to enter the relevant data; it then prompts the user for Media Type data and waits for the user to enter the relevant data; it then prompts the user for Purchase Data and waits for the user to enter the relevant data it then prompts the user for Gift data and waits for the user to enter the relevant data: it then prompts the user for Composition data and waits for the user to enter the relevant data: it then prompts the user for Composition&#39;s associated Performer data and waits for the user to enter the relevant data. 
     FIG. 3b illustrates the display 14 when the SEARCH function key is selected on the keypad 13. Selecting this function allows the user to search recorded albums&#39; description data and related purchase data stored in RAM 8 data. The mode selector switch 18 needs to be in the MEDIA position.
