     INVENTION  
      This invention relates to a computer system and, more specifically, to a computer system comprising a mobile core computer and any suitable enclosure.  
     BACKGROUND OF THE INVENTION  
      The parent applications disclose a computer system having two structures, a mobile core unit and an enclosure capable of enclosing and cooperating with the core unit. The core unit in these parent applications has all of the components of a general purpose computer except for a display and source of power. The core unit itself is non-functional as a computer unless it is in electrical contact with the enclosure. Each of the core units in the parent applications as noted have all of the components of a general purpose computer (“conventional computer”) i.e. a processor, memory means, internal storage means, activation means, video display controller, input/output controller means, as well as external connector parts. Thus, by “self contained” as used throughout this disclosure and claims is meant a general purpose conventional computer with conventional computer components (except for power and display) but when in an enclosure also has built-in capacity to interface with external sources of data and information. Also, the self-contained core computer of this present invention has unique means to electrically connect to a plurality of equally unique different enclosures, such as other computers including mobile, laptop or base computers, cars, appliances, televisions, home systems, such as alarms, electrical and heating systems, office units and equipment such as fax machines, copiers, telephones, dictating equipment and the like or any other suitable enclosure. The core unit of this invention, while it has all of the components of a conventional computer, will not function as such unless it is attached to a mating enclosure.  
      In U.S. Pat. Nos. 5,305,244 and 5,844,824, a mobile user-supported computer apparatus is disclosed having means for attachment of the computer and display or just the display to a user. The user-supported computer disclosed in these applications or patents is commercialized under the trademark “Mobile Assistant” which is a registered mark of Xybernaut Corporation of Fairfax, Va. The Mobile Assistant is very lightweight, versatile, efficient, can be attached to a user and is voice activated thereby leaving the user&#39;s hands free to repair or otherwise carry on the work being done.  
      There are known various systems for using removable modules or motherboards for use in other computers or structures. These modules typically have only one function are not a fully functional independent computer. Also known are removable dockable mobile computers that are fully functional computers that may be inserted onto a docking station to further enhance their functions. It is important to note that these prior art dockable computers are fully functional computers independent from and apart from their docking stations. Some of the systems are disclosed in U.S. Pat. Nos. 5,396,400; 5,488,572; 5,526,493; 5,608,608 and 5,627,974. Register, U.S. Pat. No. 5,396,400 discloses a computer  10  having an original equipment removable motherboard  18  that can be replaced with a notebook computer as shown in  FIG. 3  of Register. Motherboard  18  of Register is a flat panel having all components thereof exposed. The disclosure of Register is clear that motherboard  18  can only be used with computer  10  or like computers and not different type enclosures. In U.S. Pat. No. 5,488,572 (Belmont), a notebook computer which is fully functional before docking is docked on a motorized expansion base unit. Before the docking event occurs, the notebook computer communicates with the expansion base unit via a sense signal. This notebook computer and docking station are specifically designed to work together and interact. The notebook computer is not a universal computer that can be used with other docking stations indiscriminately. In Belmont, if the expansion base unit determines that the notebook computer is in a proper state for docking, it activates its motor to load the notebook computer. This is a very specifically designed system where the notebook computer and the docking station must be specifically structured to accept each other. The docking base unit cannot accept other computers not intended to be compatible therewith.  
      U.S. Pat. No. 5,526,493 (Shu) discloses another docking system for computer expansion. The Shu system relieves a computer user of the task of manually placing the portable computer in the suspend mode prior to docking with the docking station. Here again, the portable computer  12  of Shu is a fully functional computer before being docked with docking station  14 .  
      U.S. Pat. No. 5,608,608 (Flint) discloses the use of two chassis and a cartridge having separate functional components that interface with one another over a common bus. Flint&#39;s cartridge has only a processor and memory combined to a second bus and at least one slot for housing a communication module that is coupled to a second bus. The cartridge is intended for use in laptops, notebook and sub-notebook computers. The cartridge of Flint does not process the functions generally required in a general purpose computer, specifically storage means for data, operating systems and software and video display interface electronics, both of which are contained in the chassis of Flint, not the cartridge. Therefore, the cartridge is dependent on at least one of the two chassis for data retrieval, operating software, application software and video interface, all of which are needed for full functionality of the computer as whole. As will be described later in this disclosure, the presently described invention contains all of the storage, processing, video interface and software in the core unit which allows this core to be used with any closed housing without concern for the version of operating software, application software or video setting. In Flint, these settings must all match properly for the computer to function. In addition, Flint requires three separate components (two chassis and the cartridge) while the invention herein requires only two components.  
      Watts, U.S. Pat. No. 5,627,974 provides a computer docking system having connection means for connecting a portable computer to a docking station and means for allowing a microprocessor in the docking station to talk to underlying software using the central processing unit of the portable computer. The portable computer of Watts is fully functional before and after docking; it can perform the usual computer functions without being docked.  
      None of the above prior art discloses the concept of a standardized mobile core unit that has universal interchangeable usage in a plurality of different functional enclosures.  
     SUMMARY OF THE INVENTION  
      It is therefore an object of this invention to provide a core computer unit devoid of the above-noted disadvantages.  
      Another object of this invention is to provide a novel core unit that is transferable from one different enclosure to another that is not part of the original equipment of a computer.  
      A further object of this invention is to provide a self-contained uniquely designed core unit that will either continue to function in its current enclosure environment or can be used in an entirely new way in its second environment of a second different enclosure.  
      Still a further object of this invention is to provide a simple-to-use substantially reduced (in size) core unit adapted for easy use by the layman with little or no computer training.  
      A further object of this invention is to provide a self-contained uniquely designed core unit that will, when removed from the first enclosure and inserted into a different second enclosure, either continue to operate in the same manner or operate in an entirely new way in its second enclosure environment.  
      Yet a further object of this invention is to provide a core computer unit that is easily removed from one enclosure to be inserted into a second different enclosure and used in a different way in each enclosure.  
      A still further object of this invention is to provide a core computer unit that can operate in any compatible enclosure or environment while maintaining security for the data.  
      Another object of this invention is to provide a portable computer core unit that can be uniquely designed so as to fit in any equally uniquely designed enclosure such as office equipment, homes, cars, televisions or other enclosures.  
      One aspect of the present invention is a computer system comprising at least two separate compatible structures, a first structure, a second structure, and a connector, the at least one first structure comprising a housing, components of a computer coupled to the connector minus all peripheral component circuitry and related connectors, including internal non-volatile mass storage coupled to the connector, wherein the non-volatile mass storage retains stored information even when separated from said second structure, means to seal the housing of the at least one first structure, wherein the components of a computer are not removable, the at least one second structure comprising peripheral connector ports and circuitry coupled to the connector, a power supply coupled to the peripheral connector ports and circuitry and to the connector, the connector comprising an interface that joins the at least one first structure and the at least one second structure, wherein the interface enables data to be communicated between the at least one first structure and the at least one second structure and power to be transferred from the power supply of the at least one second structure to the at least one first structure, wherein neither the at least one first structure nor the at least one second structure operable as a computer without being coupled by the connector.  
      Another aspect of the present invention is a computer system comprising at least two separate compatible structures, a first structure and a second structure, the at least one first structure comprising a housing, means to seal the housing of the at least one first structure, means for connecting to the at least one second structure and for solely communicating data with and providing power to the at least one first structure, components of a computer coupled to the means for connection, including internal non-volatile mass storage coupled to the means for connection, wherein the non-volatile mass storage retains stored information even when separated from said second structure, the at least one second structure comprising means for mating with the means for connection, peripheral connector ports and circuitry coupled to the means for mating, a power supply coupled to the means for mating, wherein neither the at least one first structure nor the at least one second structure operable as a computer without being coupled by the means for connection.  
      A further aspect of the present invention is a computer system comprising at least two separate compatible structures, a first structure and a second structure, the at least one first structure comprising a housing, means to seal the housing of the at least one first structure, means for connecting to the at least one second structure and for solely communicating data with and providing power to the at least one first structure, means for allowing the at least one second structure to function as a conventional general purpose computer, coupled to the means for connection, the at least one second structure comprising peripheral connector ports and circuitry coupled to the at least one first structure via the means for connection, power supply coupled to the at least one first structure via the means for connection, wherein neither the at least one first structure nor the at least one second structure operable as a computer without being coupled by the means for connection.  
      These and other objects and aspects of this invention are accomplished generally speaking by a transferable, removable and portable stand-alone substantially reduced (in size) computer core unit included in a single housing which is critical to this invention. As noted, this core unit is not a motherboard or other replaceable component of a computer. The core unit of this invention is simple, uncomplicated and is carried in a single closed housing only to be easily removed or inserted as a unit into a mating enclosure. The core unit of this invention has preferably only one uniquely configured connecting means which mates with or fits against a power connector source or activating means in an enclosure. Other than this connecting means, all of the components of the core unit are sealed and not removable from the core housing. Methods of sealing the core unit include, but are not limited to, fasteners such as screws, bolts, or other suitable devices. Other methods such as gaskets or weatherproof sealant could be used to seal the core unit. The items above are not exhaustive, but are merely illustrative of the types of ways the core can be sealed. Alternatively, the core unit maybe selectively sealed such that an end user may not open the core unit, but a qualified technician or manufacturer may access the internal components of the core unit. This same connecting means also provides communication or transfer of information over a bus or in a wireless fashion. In the core unit all of the computer components stay intact unlike the prior art where, for example, the CPU is removed and replaced with a second CPU or other components. The security offered by the core unit is provided by uniquely structured mating connection means which connect to a mate connector in the enclosure. In the event that the core unit is lost or misplaced, its data cannot be used, read or printed out by others because it can only be activated by connection to an equally unique mating connector in the enclosure. Also for security reasons, the core unit is in a completely closed housing so that no computer component may be removed, copied or tampered with. This feature is critical to this invention.  
      In the present invention, the core unit&#39;s size is substantially reduced from the core disclosed in U.S. Pat. Nos. 6,029,183 and 5,999,952 by removing all peripheral I/O component circuitry, other peripheral component circuitry and related connectors (such as the video display controller, PC Card controller, etc.) and having the peripheral circuitry and related connectors embedded directly into the enclosures. This transfer of peripheral circuitry and connectors permits a substantial reduction in size of the core unit and transfers these functions to the enclosure. In this manner each enclosure can be maximized and not restrained by the structure of the core unit. In the present invention, the “core unit” comprises as components the processor, memory, non-volatile storage, keyboard controller, power connector and support circuitry for the components. This design also provides several benefits. First, because, as noted earlier, all peripheral component circuitry is removed from the core unit, the core unit&#39;s size is reduced substantially over that of the above-described already small core units of U.S. Pat. Nos. 6,029,183 and 5,999,952. The size of these earlier cores is reduced in the present invention by at least ⅓ of the size of those cores in U.S. Pat. Nos. 6,029,183 and 5,999,952. Secondly, all I/O peripheral support circuitry and related connectors are now embedded within the enclosures, the core unit is thereby capable of driving all external components to their highest capabilities and also provides the capability for system integrators/designers to develop application specific systems based not only on user requirements but can limit the functionality of the system. Each enclosure can communicate with the core unit of this invention (via wireless or other means) to tell the core unit what features that specific enclosure can supply.  
      Finally, by developing and using this type of architecture, the number of software licenses a person or company needs can be reduced significantly. Since the core unit which contains the license software stored on non-volatile storage will always travel with the user, there would be no need for multiple software licenses (one for the office desktop, one for the laptop and one for the Mobile Assistant® thus minimizing software costs. This aspect is true for all disclosed embodiments.  
      By “enclosure”, “enclosed” or “enclosing” is meant throughout this disclosure and claims as a housing that the core unit is electrically connected to or at least partially housed by. By the term “communication activation means” is meant wireless transmission or communication, infrared, radio, cellular communication or other suitable communication means. It is also desirable that the core unit of this invention comprises compatible communication means with other devices such as cameras, monitors, printers, appliances, enclosures and other suitable devices. In this manner, the core unit can communicate with each device in a selective manner.  
      As above noted, the core unit of the present invention is entirely different than the computer devices of the prior art; in particular that disclosed in U.S. Pat. No. 5,396,400 and the cartridge unit of U.S. Pat. No. 5,608,608 earlier discussed. U.S. Pat. No. 5,608,608 (Flint) discloses the use of two chassis and a cartridge having separate functional components that interface with one another over a common bus. Flint&#39;s cartridge has only a processor and memory combined to a second bus and at least one slot for housing a communication module that is coupled to a second bus. The cartridge is intended for use in laptops, notebook and sub-notebook computers. The cartridge of Flint does not process the functions generally required in a general purpose computer, specifically storage means for data, operating systems and software and video display interface electronics, both of which are contained in the chassis of Flint, not the cartridge.  
      Therefore, the cartridge of Flint is dependent on the two chassis for data retrieval, operating software application, software and video interface, all of which are needed for full functionality of the computer as a whole. As will be described later in this disclosure, the presently-described invention contains all of the non-volatile storage, processor, memory, power connector, activation controller means and circuitry for these components in the core unit which allows this core to be used with any housing without concern for the version of operating software, application software or video setting which will be found in the enclosure. In Flint, these settings must all match properly for the computer to function. In addition, Flint requires three separate components (two chassis and the cartridge) while the invention herein requires only two components. Furthermore, Flint allows the chassis to be user configurable, whereas the core unit of the present invention does not.  
      Finally, the cartridge of Flint permits external peripheral devices or ports (e.g. PCMCIA) to be an integral part of the cartridge. Conversely, the present invention does not allow any peripheral devices or external peripheral ports to be integral in the core unit since it (core unit) has components in a completely closed housing thereby providing a secure, tamper-proof core unit. The only communication with the interior components of the core unit is through its connection means.  
      The present invention comprises a computer system completely different from the Register U.S. Pat. No. 5,396,400 docking station-computer. The following are the distinctions in the present invention from the Register Patent: 
      (A) The present core unit is completely enclosed thereby ensuring that the contained computer components may not be altered or removed. Register&#39;s motherboard is completely open and must be to function since several contacts are openly projecting from the motherboard; i.e., CPU chip  26 , memory chip  28  and board socket  30  extend from the upper surface of planar board  18 .     (B) The motherboard  18  of Register does not contain all of the components of a fully functional conventional general purpose computer. It has no disk drive for internal non-volatile mass storage means. A mass store means allows a computer to permanently retain large amounts of data; motherboards do not contain disk drives. The present core unit does.     (C) The present core computer unit is not an original component or part of a computer as is Register&#39;s motherboard. The present core computer unit is not originally part of a computer but rather a free-standing unit.     (D) The present core computer unit has means to retain stored information to be used in a plurality of different type enclosures. Register&#39;s motherboard can only be used with the same type enclosure.     (E) The present core computer unit has means to be used interchangeable with a plurality of different type enclosures. Register&#39;s motherboard cannot be used interchangeable in other different type enclosures.     (F) The enclosure or second structure of the present invention may be enabled to be part of another third structure and not just a stand-alone computer. Register is completely silent on this feature.    

      The core unit of this invention is small, compact and self-contained. Each of the enclosures that the core unit can be inserted into can have its own set of distinct peripheral devices, peripheral circuitry, peripheral connectors or peripheral connector ports for performing singular or multiple functions; for example, if a technician in a factory has the responsibility to perform inventory control, the core unit would be inserted into an enclosure that has connector ports that are specific to perform the inventory functions (e.g. port for a bar code scanner and communications to a remote computer). If the same technician has the responsibility to repair and maintain equipment in that facility, the technician could remove the core unit from the inventory enclosure, insert the same core computer into a different enclosure that has, again, distinct peripheral devices or connector ports specific to performing maintenance functions (e.g. 1553 interface for performing non-intrusive testing of equipment, head-mounted display port and a digital multi-meter for taking electrical readings) and therefore function as a repair and maintenance computer. Additional security means can be inserted into the technician&#39;s core unit if security becomes important in use to allow only or her access to enclosures or systems.  
      The same technician might also have an office and need access to, and operate from, a laptop computer. The core computer used in the above examples could also be inserted into a laptop enclosure where all peripheral connector ports, embedded peripheral devices (e.g. CD-ROM reader) and means for providing power are in an enclosure that looks like a laptop. When the core unit is inserted into the laptop enclosure, the unit would function as a traditional laptop.  
      The above examples show the versatility of the core computer to be used in a variety of different enclosures or different environments and situations without the need for three different computers to perform the various functions (inventory control device, test equipment and computer and laptop computer).  
      By keeping the core unit and its interface standard, users can make one-time investment in the core computer and allow enclosures to dictate the function. Likewise, functions or procedures differ from company to company; therefore, a company can now determine what enclosure functions are necessary to perform their missions (e.g. inventory control, repair and maintenance, general office computers) and build their enclosures accordingly.  
      Each of the enclosures into which the core unit can be at least partially inserted will have their own peripheral external connecting ports, peripheral circuitry, peripheral connectors and all I/O component circuitry. For example, if the core unit is removed from an office located computer or other enclosure, it can be inserted into a console of a car where the console has externally connected ports to car functions to be monitored such as disability function for security, brakes, motor, transmission, telephone, geographical information systems and the like. When the car is taken in for repairs, the core unit is simply removed and given to the mechanic who will then insert it into his diagnostic equipment with a suitable mating connector to determine the cause of the car problem. This would act in this instance as a “Black Box” (as used in airplanes) for cars and could also replicate a complete office environment. This same core unit can then be inserted, for example, into a home electrical control enclosure to regulate the on-off lights, air or heating system of the house. Naturally, the enclosures need to have special uniquely structured connector means so as to accept the core unit with a mating connector. Therefore, the special connector core unit of this invention can be used as a single portable unit that will supply or replace office computers, car computers that regulate the memory for security, information read out, seat&#39;s temperature, etc. Home regulators of light, heat, air and TV can be used as a total core computer insert to any mobile or stationary computer. The specially designed core computer unit of this invention can easily be carried from one enclosure to another and will operate in any environment. It is truly the universal-personal computer in that it can go wherever the user goes; to be used in whatever environment he or she finds themselves. Each enclosure in a preferred embodiment can have its own display or monitor and power source. For example, the car enclosure can have a small display on the dashboard, a mobile wearable computer (such as the Mobile Assistant®) can have a head, wrist-mounted, shoulder or eyeglass-mounted display, the home monitoring system can use the TV screen as a display, etc. Obviously, if desirable and suitable, the enclosure can be used without a display. The power source available in a car, home or mobile computer such as a battery or electrical system will be used to power the core unit of this invention. The core unit must be housed in a mating enclosure before it could function as a computer. The term “housed” throughout this disclosure and claims means that the core unit is at least partially contained in said enclosure or in electrical or physical contact with the enclosure.  
      The components for the universal core unit of this invention can be similar to those disclosed in U.S. Pat. No. 5,305,244 which is incorporated by reference into this disclosure. The CPU, for Example, can be an 80286, 80386SX,  80486  or Pentium microprocessor available from Intel. The enclosures will include different interfaces and controllers for use with other types of peripherals such as Cardbus, other communication devices or the like. Circuit cards such as those obtained from Dover Electronics Manufacturing of Longmont, Colo. and Ampro Computers of Sunnyvale, Calif. can be used in the core unit, if desired. If the core unit is voice activated, it could contain a voice-recognition engine available from Dragon Systems, Newton, Mass. used in connection with a sound card. Other components used in the core unit of this invention are off-the-shelf, presently available components such as those disclosed in U.S. Pat. No. 5,305,244 and U.S. Pat. No. 5,844,824. The core unit is different in that it cannot operate as a computer until inserted into a special enclosure which will only accept core units with a unique connector means, thus a very secure system may be provided.  
      The transferable and removable standardized core computer unit of this invention includes a single housing comprising therein standard features of a self-contained general purpose computer minus all peripheral component circuitry and related connectors. In the preferred embodiment, the peripheral I/O component circuitry must be put in the enclosure(s) and not on the core computer unit. The core unit of this invention contains power connection means, a CPU, memory means, non-volatile storage means, activation controller (such as a keyboard controller or audio recognition means and circuitry) for these components. The enclosure unit has at least one electrical connector means for connection to a bus connection and to a source of power outside the enclosure. It will only work off the source of power provided by or through an enclosure and will not function as a stand-alone unit if directly attached to a power source. The enclosure comprises peripheral connector ports or devices to cooperate with said core computer unit when said core unit is placed therein and the core computer unit has means to cooperate with a plurality of different enclosures when inserted into said enclosures in either an original placement or transferred from another enclosure. The core computer unit has activation cooperation means for interaction with the desired activation means. The activation means are selected from the group consisting of audio activation means, communication activation means, pen activation means, brain activation means, eye-tracking activation means, mouse activation means, a keyboard activation means and mixtures thereof. The core unit has no removable components and will not function as a computer without said enclosure.  
      The core computer unit of this invention can be removed from a laptop enclosure and inserted into a mobile body worn enclosure to become thereby a mobile body-worn computer as another example of its use. This type of usage is important since the core unit of this invention can be interchangeably used in an infinite number of conforming enclosures with mating connector. Such an enclosure could have means to allow it to monitor all office functions, an enclosure(s) in a car, such as in the console in an arm rest or dashboard, an enclosure in an vehicle, an enclosure in a home appliance or a house system, such as an alarm or heating system or an electrical system, in an enclosure in test equipment, television, and the like. Each enclosure is specifically structured to accept the equally specifically structured core unit of this invention. Thus the same core unit can be used if desired in several mating enclosures in the same day or period. The core computer&#39;s memory and storage means can, for example, carry over a project from the office to the home to ensure continuity of a project, while as above noted providing optional security since it will only function in a properly mating enclosure and can employ a means that limits the specific enclosures that one, or one type of, core unit can operate with. The core unit can have such further security means included therewith. It (same core unit) can be used sequentially, for example, in the office, in the car while traveling home or at home. Each enclosure will have ports for various functions such as connection to a head set or display means. The core unit of this invention will comprise as components a CPU, memory means, internal non-volatile mass storage means, activation controller means, power connector and support circuitry for these components. The core unit will not function as a computer unless it is in or on or in electrical contact with a specifically designed mating enclosure. The enclosure supplies the display when needed, the power supply (activation) for the core unit and provides the ports for peripheral external connections, such as connection to a display or printer, peripheral circuitry and related connectors. The enclosure and core unit have uniquely configured mating connection means for power and allowing communication of the core to the enclosure. The enclosures must rely upon the core for general computer functions. The enclosures supply to the system herein described, the power means and connections to peripherals, such as a display, sensors and controls, etc. The enclosures are inert as a general computing device until the core unit is inserted therein, but unlike the prior art docking systems, the core unit does not function or is activated apart from the enclosure and the core unit has all of the components of a conventional computer except a display and at least one connector to a direct power connection, and communication bus; it is always activated only by a unique connection or connections to an enclosure. This is critical to the present invention. By “conventional computer” is meant a single completely closed housing comprising a CPU, memory means, internal non-volatile storage means, activation means, video, I/O interface, support circuitry, but in this invention a the core does not include the I/O or other component circuitry and related connectors. In one embodiment, the enclosure is enabled to be connected to another structure such as part of a computer, telephone or local network system, car, part of test equipment, part of the electrical system of a building. The enclosure has a uniquely designed electrical connector that only fits or mates with the uniquely designed mating connector of the core unit, such a coupling, however, may take on a number of designs.  
      As noted above, the core unit and the enclosure must have unique or specially designed connectors to both function and for security reasons. There are many different unconventional connectors that can be used such as specially configured tongue and groove connectors, dove tail connectors, bar connectors, slot and projection connectors, etc. The more unique the communication or connectors, the better the security of the core unit. Obviously, any other security means may be incorporated into the system of this invention if desirable to further enhance the security of the system.

     DETAILED DISCUSSION OF DRAWINGS AND PREFERRED EMBODIMENTS  
      In  FIG. 1 a  core unit  1  is shown before it is inserted into an enclosure  2 . As noted above, core unit  1  contains all of the components of a conventional computer except for a display. Also the core unit  1  will not function as a computer unless it is inserted into enclosure  2 . By itself core unit  1  is totally inert and no information or data can be extracted therefrom unless it is mated with an enclosure with a compatible connector means. The connector means  3  of core unit  1  is a metal bar that can be configured in any design as long as it is compatible with the connector means  4  in the enclosure  2 . For security reasons, the more unique mating connector means  3  and  4  are configured, the higher degree of security to the contents of core unit  1  will be afforded. The connector means in  FIG. 1  are kept relatively simple in structure for illustration purposes only, i.e. to show how they mate with each other. Obviously customized connectors with one-of-a-kind structures with for example security codes would supply optimum security. The core unit  1  does not have its own display and must rely upon enclosure  2  to supply same. This is accomplished by peripheral ports  5  in any side of the enclosure  2 ; these ports connect to display means or any other extended connection required. The connections of the core unit  1  to these ports is not shown in the drawings for clarity purposes; any known conventional circuitry or electrical connections obviously can be used. The enclosure  2  maybe connected either directly or indirectly to a structure  6  such as the console of a car, test equipment, house electrical system, other computers, etc. Once core unit  1  is in place as shown in  FIG. 2 , the electrical connector means  3  and  4  engage each other and the core unit  1  is now activated and will function as a computer unit with enclosure  2 . As noted earlier, the only communication with the interior computer components of core unit  1  is through connector means  3 . No PCMCIA or other ports are found in core unit  1 . This is important to the present invention. A monitor or display is connected thereto by cables  7 , other ports or interconnectors  5  in enclosure  2  can be used for connection to other peripheral functions. The core unit  1  shown in  FIG. 1  if lost or misplaced would be useless to someone other than the owner of a matching enclosure  2 . With customized connector means in the core  1  and enclosure  2  third parties would not gain access to information in core unit unless they also possessed similarly the matching enclosure(s). Security can be further enhanced under program control or by pre-programming before distribution. The core unit  1  by itself is inert as is the enclosure  2  by itself. A core unit  1  of a user is not interchangeable with a core unit  1  of another user; each is a customized design.  
      In  FIGS. 3-6  different configured connector means are shown; however, these are merely shown to illustrate—not limit the concept. A power source cord or other means  33  is shown in electrical contact with each enclosure  2 . In  FIG. 3 a  dove-tail connector  8  is shown that would be attached to core unit  1  and would slide into dove-tail recess  9  of enclosure  2  when core unit  1  is inserted into enclosure  2  as shown in  FIG. 2 . The ports  5  can be located in any side of enclosure  2 ; for example, in  FIG. 3  the ports  5  are located in a back section of enclosure  2  whereas in  FIG. 4  the ports  5  are located in a front side section of enclosure  2 . In  FIG. 4 a  triangular connector  10  of a core unit  1  will fit into a triangular slot or recess  11  in enclosure  2 . All of the electrical connectors shown in all of the  FIGS. 1-6  are conductive connectors used to activate the computer functions of core unit  1 . Unit  1  can have activable activating means as described in parent U.S. Pat. No. 5,948,047 the disclosure of which is incorporated by reference into this application. Once activated, readout of data or information from core unit (or print out) can be accomplished by cable connectors  7  that can be connected to a monitor, printer or any other desired structure. Each of the connectors of  FIGS. 3-6  obviously are attached to a core unit  1  which is not shown in  FIGS. 3-6  for clarity. These connectors should extend from the side of unit  1  similar to the connector  3  of  FIG. 1 . In  FIG. 5 a  core unit rectangular connector  12  is shown as it will fit into a rectangular slot  13  in the inner face of enclosure  2 . All of the slots or recesses have conductive linings so that there would be electrical communication when each core unit connector is inserted therein. In  FIG. 6  another embodiment of matching unique connectors is illustrated where peg-like metallic or other conductive connectors  14  which would be attached to core unit  1  are ready to be inserted into mating conductive apparatus  15  located in enclosure  2 . While uniquely configured connectors are highly preferred for security of core unit  1  contents, obviously conventional connectors may be used together with or in lieu of one-of-a-kind type connectors, if desirable. In that case, security may be compromised and interchangeable conventional connectors would allow more universal usage. In each case, the enclosure  2  as noted earlier is part of a larger structure  6  such as an airplane, home, car, office equipment, medical or other test equipment and any other structures where private data communication is desired.  
      Unlike prior art systems where interchangeable modules usually containing only one primary module function are known, in the present invention core unit  1  is a completely fully functional computer without a display and power supply which is inert until combined with an enclosure(s)  2 . The capacity and speed of each core unit can be made compatible with the state-of-the-art computer science as with the enclosures used. The present invention provides a system unobvious over the prior art computer docking station art where the computer being docked (in prior art) is fully functional apart from or in docked state. The computer core unit  1  is never functional until inserted into the enclosure  2 . Any system or activation means of commonly owned U.S. Pat. No. 5,844,824 may be used in the present invention. The disclosure of U.S. Pat. No. 5,844,824 is incorporated by reference into this application.  
      In  FIG. 7 a  piece of medical, analytical, mechanical, electrical, or any other test equipment  17  is shown having port  18  for connection to a printer, port  19  for connection to a multimeter reader, and outlet  20  for connection to a source of power. A mating core unit  1  is shown before it is inserted into enclosure  2 . Note that the core connector means  3  is located on the front side of the totally enclosed core unit housing. Once inserted into enclosure  2 , the connector means  3  will make and maintain contact with enclosure connector  4 , thereby supplying the power to run the computer of core unit  1 . Also connection of core  1  and enclosure  2  provides communication or transfer of information over a bus located in the enclosure  2 . The test equipment  17  has a monitor  22  and controls  21 . As earlier stated, the test equipment  17  can be of any type. The user can customize the connectors  3  and  4  so that they are unique and test results (for example, medical) can be maintained confidential.  
      In  FIG. 8 a  wearable computer  23  such as the Mobile Assistant can have an enclosure  2  integral therewith. The computer  23  by itself will not function as a computer until and unless the core unit  1  is inserted therein in electrical contact with the enclosure  2 . A power port  25  is located in computer  23  for connection to a battery. A uniquely configured core unit connector  3  is shown on the longitudinal side of core unit  1 ; however, the connectors  3  and  4  can be located on any portion of core housing and enclosure  2 . A port  24  is provided in mobile computer  23  for connection to a monitor or display.  
      In  FIG. 9 a  desk  16  is illustrated having a built-in enclosure  2  located at any convenient part of desk  16 . The desk  16  is provided with a monitor  26 , which will be functional upon activation of the core unit and enclosure system. The office worker may need to later transfer the core unit  1  from desk  16  to a laptop or to the mobile computer of  FIG. 8 . He or she can continue their desk work contained in core  1  in their car or in a mobile computer  23  by using the same core unit  1  upon transferring it from desk enclosure  2  to mobile computer enclosure  2 . Or, core unit  1  once removed from desk enclosure  2  can be used in a totally new and different environment when used in a car or in mobile computer  23 .  
       FIG. 10  illustrates a completely enclosed unit housing  27 , having only one communication means  3  to other structures. As earlier noted, the connector means  3  can be on any external portion of unit housing  27  of unit  1 . Connector  3  is connected to a connector  4  in the enclosure  2  for power and bus connection between the two components  1  and  2 . It is important that no computer component is removable from unit  1 .  
      The illustration of  FIG. 11  shows a core unit  1  before it is inserted into an enclosure  2  located in the arm rest, console, dashboard, or any other section  28  of a car or vehicle. Here the connector  3  is located on the bottom of totally enclosed core unit housing  27 . The armrest  28  (or other car portion) has ports  29 ,  30 ,  31 , and  32  for connection to the car&#39;s sensors, GPS, display and car communication system, such as cellular phone. The core unit  1  can monitor any and all functions of the car and yet can be removed and used in a desk in a completely different environment.  
      The armrest  28  or other car portion having an opening acting as the enclosure  6  could, of course, be used to house a radio, a telephone or any other suitable electronic item besides core unit  1 . Alternatively, combination core unit-radio, or core-unit telephone or core unit-any electronic structure may be used in the enclosure  6  and be within the spirit of this invention. In other words, the core unit  1  of the present invention may be used alone in enclosure  6  or may be combined with any other electronic structure when used or housed in enclosure  6 .  
       FIG. 12  illustrates another view of the core unit of the present invention. The housing of the core unit  1200  is shown divided into two halves, an upper portion  1201  and a lower portion  1202 . The lower portion  1202  of the core unit may contain computer components that are not removable or upgradeable. The lower portion  1202  is sealed or secured to the upper portion  1201  of the core unit  1200  using non-removable or tamper-proof screws or fasteners  1203 . Gasket or seal  1204 , positioned between upper portion  1201  and lower portion  1202  of the core unit  1200  may be used to provide additional security to ensure that the core is a sealed unit. Gasket or seal  1204  may be made of rubber or similar type material. The core unit  1200  houses computer components  1206  and a single interface  1205  electrically connected to the computer components  1206  which mates with a reciprocal interface in the enclosure.  
      The computer components  1206  contained within the lower portion  1202  of the core unit  1200  include components such as a motherboard, a processor, memory, and buses. The enclosure or second structure would contain peripheral circuitry components such as video hardware, sound hardware, and input output ports. The processor may be, for example, a central processing unit (CPU), a micro-controller unit (MCU), digital signal processor (DSP), or the like. The memory may be a read only memory (ROM), a random access memory (RAM), or a memory with other access options. The memory may be physically implemented by computer-readable media, such as, for example; magnetic media, such as a hard disk, a floppy disk, or other magnetic disk, a tape, a cassette tape; optical media, such as optical disk (CD-ROM, DVD); semiconductor media, such as DRAM, SRAM, EPROM, EEPROM, or memory stick. The memory may store and support modules such as, for example, a basic input output system (BIOS), an operating system (OS), a program library, a compiler, an interpreter, a text-processing tool, and other programs such as database, word-processor, web-browser, and voice-recognition.  
      The computer components  1206  contained within the lower portion  1202  of the core unit  1200  described above are secured to the lower portion such that they are not removable or upgradeable. Securing the computer components can be achieved in multiple ways. First, by virtue of the non-removable screws or fasteners, the core unit  1200  is sealed. In addition, the computer components may be soldered to the motherboard using fusible alloys, such as tin and lead or may be secured using electrically conductive epoxies. Electrically conductive epoxies are well known and include epoxies sold by Epoxy Technology of France and Emerson &amp; Cuming, for example. Other conventional or newly developed methods of securing computer components to a board structure (i.e., motherboard) are envisioned within the scope of the present invention.  
      The lower portion  1202  is sealed or secured to the upper portion  1201  using non-removable or tamper-proof screws or fasteners  1203 . The types of non-removable, tamper-proof screws or fasteners that can secure and seal the core unit  1200  are well known. Examples of such fasteners include those sold by Bryce Fastener Mfg., Inc. of Gilbert, Ariz. which include KEYED-LOK, PENTA-PLUS, and the Spinlok. Other types of tamperproof screws may be used as long as they provide the ability of the core unit not to be opened using conventional methods. The figure illustrates the core unit secured with four non-removable screws or fasteners; however, this is only illustrative and not meant to limit the present invention. The core can be secured with more or less than four non-removable screws.  
      The preferred and optimumly preferred embodiments of the present invention have been described herein and shown in the accompanying drawings to illustrate the underlying principles of the invention, but it is to be understood that numerous modifications and ramifications may be made without departing from the spirit and scope of this invention.
