Description:
FIELD OF THE INVENTION  
         [0001]    The present invention relates generally to wearable computers and, more specifically, to methods and arrangements for facilitating the connection of auxiliary components therewith.  
         BACKGROUND OF THE INVENTION  
         [0002]    As miniaturization of computer products continues, the problem of adequate space for connections of input and output devices (I/O) continues to grow. The minimum size of many computer products are now being defined by the number and type of connectors used, especially on the highly integrated devices of the type used in wearable computer technology. In other words, since it is the case that a minimum amount of space must typically be allocated for accommodating connectors or connecting interfaces in the environment of a wearable computer, it has been found that further efforts towards miniaturization in the context of wearable computers has been hampered.  
           [0003]    A need has thus been recognized in connection with facilitating further miniaturization in the context of wearable computers by reducing the amount of space associated with connectors, connection interfaces or other connecting elements.  
         SUMMARY OF THE INVENTION  
         [0004]    In accordance with at least one presently preferred embodiment of the present invention, a single docking-type connector is provided on a computer system unit, and distributes the I/O connectors required for a given task, into the harness (wearing device) of the computer. The docking connector preferably has enough pins to carry all of the I/O signals, power and grounds for the computer.  
           [0005]    Successful wearable computers will offer flexible configurations of I/O and wearing possibilities. Because the system unit has all of the possible I/O signals, different types of harnesses (as variously illustrated by way of example in the drawings) allow for many configurations. The harnesses with the cabling are relatively inexpensive compared to the system unit.  
           [0006]    Generally, in accordance with at least one presently preferred embodiment of the present invention, problems relating to the space taken up by connectors are solved by essentially exchanging the multiple connectors required for I/O on a system unit for a single docking connector. By redistributing the individual connectors into various harnesses and docking stations, the system unit is greatly reduced in size and can achieve attendant advantages as discussed herein.  
           [0007]    In one aspect, the present invention provides a connector system for a computer, the connector system comprising: a docking connector which interfaces with a system unit; a plurality of leads in communication with the docking connector; and a plurality of connecting elements associated with the plurality of leads, the connecting elements each being adapted to interface with at least one external component.  
           [0008]    In another aspect, the present invention provides a harness system for supporting a portable computer, the harness system comprising: a harness which accommodates a system unit; a docking connector which interfaces with the system unit; a plurality of leads in communication with the docking connector; and a plurality of connecting elements associated with the plurality of leads, the connecting elements each being adapted to interface with at least one external component.  
           [0009]    For a better understanding of the present invention, together with other and further features and advantages thereof, reference is made to the following description, taken in conjunction with the accompanying drawings, and the scope of the invention will be pointed out in the appended claims.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0015]    [0015]FIG. 1 provides a comparison of the respective space requirements for a docking connector  100  that may be employed in accordance with the present invention and a conventional set of connectors  102 . As a non-restrictive, illustrative example, the docking connector  100  may be 160 pin. On the other hand, indicated at  102   a  is what may be regarded as a “bare minimum” set of conventional connectors for a wearable computer, including a video connector, a mouse connector, a Universal Serial Bus (USB) connector and DC/V (electrical power) connector. The balance of the illustrated connectors  102 , on the other hand, represent what is additionally attainable in connection with the docking connector  100 . (Among these, for example, are KB [keyboard], USB, a “Send” connector, a “Parallel” connector, a DVI [digital video interface] connector, and a PCMCA connector). Thus, it will be appreciated that a docking connector  100 , in accordance with at least one embodiment of the present invention, will be able to serve essentially the same functions, in composite, as the multiple connectors  102 . The savings in frontal area (i.e., the area corresponding to an opening in a computer cover) gained by removing the connectors from the system unit and distributing them to the harness are apparent from FIG. 1. For a typical wearable computer system unit, it has been found that the use of the totality of connectors  102  might represent about 77.% of the area on the edge of the system unit (i.e., the normal place to put connectors extending from the edge of the card), while the figure for the minimum set of connectors  102   a  might be about 19.5% and, for the docking connector  100 , 6.3%.  
         [0016]    [0016]FIG. 2 shows how the distribution of various connectors may take place in a harness. As shown, a system unit  104  has a docking connector  100 . Docking connector  100  may preferably be a detachable component that mates with the main body of the system unit  104  itself. Preferably extending from docking connector  100  are a number of harness connectors  106  (for instance, PCMCIA/RF LAN, DVI, “Mouse”, USB, DCV, etc. . . ). There is preferably a printed circuit board (PCB) with all of the harness connectors  106  wired in “pigtail” fashion. The harness leads  106  may preferably be laid out about the harness  108  in such a manner that the individual connecting elements  107  may be located at different points along the circumference of harness  108 . As shown, a handheld mouse  109  may be connected with a corresponding connecting element  107 . Harness  108  may also preferably accommodate batteries  110  as well as a head mount display  112  having a lead that is connected with one of the connecting elements  107 .  
         [0017]    It will be appreciated that the approach contemplated in connection with FIG. 1 will allow the system unit  104  to be easily removed with only one connection. A system unit  104  such as that shown in FIG. 1 may conceivably have a size of about 15×65×120 mm, which would represent a degree of miniaturization far greater than that previously attainable without a distributed connector system.  
         [0018]    A preferred manner of “stepping down” the connection elements  107  into the connection leads  106  and then into the connector  100  may involve a one-to-one correspondence between each of the pins in each of the connecting elements  107  and each of the pins in connector  100 . It should be understood, though, that it is conceivable to only use some of the connections so that some of the pins in connector  100  are not actually used.  
         [0019]    [0019]FIG. 3 shows an individual  114  wearing the wearable computer system of FIG. 2.  
         [0020]    [0020]FIG. 4 shows an individual wearing a belt-type harness  116  with a computer having a direct view screen  118 . It will be appreciated that such a configuration is attainable in conjunction with a distributed connector system in accordance with at least one embodiment of the present invention.  
         [0021]    [0021]FIG. 5 shows a miniature computer  120  in conventional docking with a desk top computer  122 . It will be appreciated that such a configuration is also attainable in conjunction with a distributed connector system in accordance with at least one embodiment of the present invention. In this case, the miniature computer  120  could subsequently form part of a wearable computer system, or it could be used in other contexts where it is not necessarily “worn” by an individual.  
         [0022]    It will be appreciated that the approach contemplated herein provides several advantages. For one, the docking connector will almost certainly be smaller in both volume and area than the combination of the minimum number of connectors required, making the computing system unit as small as possible. Secondly, because all of the I/O possibilities are accounted for in the docking connector and the custom harness, it allows for a modular system of computer and harness and the designer can avoid compromises of leaving off connectors of the system unit because of limited space. Preferably, the harness will be customized for the task. Thus, not only will all of the right connections be available for the I/O, but only the ones required will be used, thereby saving weight, which is widely recognized as being an important characteristic for all wearable devices.  
         [0023]    Another advantage enjoyed in connection with at least one presently preferred embodiment of the present invention is that wearable computers, in general, may sometimes be used in harsh environments (often outside or in industrial settings) and need to be rugged and, quite often, resistant to dust and water. By reducing the I/O connections to the one docking connector on the system unit, the integrity and durability of the system is facilitated since the number and size of openings in the system covers will be limited; the unit will be stronger and easier to seal.  
         [0024]    Finally, as far as wearablilty and the management of cables is concerned, having only one connector on the system unit allows the designer to manage the cables coming from the unit into the harness and avoid a “rats nest ” of cabling coming off the unit in less than ideal directions. In addition to saving the connector area and volume on the system unit, the inventive design serves to move the volume used by the cable end of the connector to areas away from the system unit, distributing that volume into the harness. By not having connectors exiting from many sides of the system, there is more flexibility for the manner in which the unit is mounted and worn on the user&#39;s body.
