     The detailed embodiments of the present invention are disclosed herein. It should be understood, however, that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limiting, but merely as the basis for the claims and as a basis for teaching one skilled in the art how to make and/or use the invention. 
     With reference to  FIGS. 1 ,  2 ,  3  and  4 , and in accordance with a first embodiment of the present invention, an automobile entertainment system  110  is disclosed. The automobile entertainment system  110  is composed of a series of video and audio components integrated within an automobile  111 . As those skilled in the art will certainly appreciate, the various embodiments of the present entertainment system are disclosed herein with reference to their use within an automobile. However, the entertainment system could certainly be used in other vehicles, for example, boats or planes, without departing from the spirit of the present invention. 
     Referring to  FIGS. 1 ,  2 ,  3  and  4 , a video system  112  and mounting structure are disclosed. The video system  112  is adapted for selective mounting within the ceiling  113  of an automobile  111 . It is further contemplated those skilled in the art will appreciate the concepts underlying the present invention provide for the possibility of selectively mounting the video system within a variety of locations within an automobile, for example, the dashboard of an automobile. 
     The video system  112  is detachably mounted within a cradle  138  secured to the ceiling  113  of an automobile  111 . The video system  112  generally includes a video monitor  116  for presenting media content and a video source  120  integrated therewith. 
     In accordance with a preferred embodiment of the present invention, the video source is a DVD player coupled to the video monitor  116  for the transmission of video content thereto. The DVD player, or other video source  120 , is integrated within the same video housing  118  as the video monitor  116 . In addition to, or in place of, video source  120  it is also contemplated a hard drive video source  123  may be integrated with the video monitor  116 . The hard drive  123  includes inputs for receiving video content and outputs for transmitting video content to the video monitor  116 , both of which are well known to those skilled in the art. However, and as those skilled in the art will certainly appreciate, the video source may take a variety of other forms (for example, universal media disk) without departing from the spirit of the present invention. 
     The video monitor  116 , DVD player  120 , hard drive  123  and associated control components are mounted within the housing  118 . In accordance with a preferred embodiment, the video monitor  116  is a TFT LCD screen. However, it is contemplated other monitor constructions, for example, plasma, Ultra High Definition VGA, touch screen VGA, organic LED, fabric based monitors (e.g., flexible TFI) etc., may be used without departing from the spirit of the present invention. 
     With regard to the DVD player  120 , it is integrally molded within the housing  118  and positioned for insertion of the DVDs behind the video monitor  116 . By mounting the DVD player  120  in this way, a stable structure is developed that is well adapted for the automobile environment. While the DVD player is disclosed as being a slot-loaded design with insertion behind the video monitor, the DVD player could take a variety of other forms without departing from the spirit of the present invention. Those skilled in the art will appreciate the various DVD designs that may be employed, for example, many can be seen in U.S. patent application Ser. No. 11/177,405, which is incorporated herein by reference. 
     Referring to  FIG. 5 , an alternate modular video system  112 ′ is disclosed. In accordance with this system, the various components are not hardwired but are incorporated within the video system  112 ′ via interchangeable modules. For example, the video system  112 ′ is provided with a removable and interchangeable module  120   a ′ in which a hard disk drive, flash memory drive, DVD player/recorder, CD player/recorder, Blue Ray player/recorder, and an auxiliary battery may be incorporated. As those skilled in the art will certainly appreciate, other slot type modules are utilized within the electronics industry and these may also be incorporated into the video system  112 ′. For example, a slot for a PCMCIA Card and/or Ie:Cell.Air card  120   b ′ for downloading materials may be incorporated. Similarly, memory cards  120   c ′ and USB cards  120   d ′ may be incorporated into the video system  112 ′. 
     The video system  112  is detachably mounted within a cradle  138  formed in or secured to the ceiling  113  of the automobile  111 . The design of the video system  112  and cradle  138  allows for the creation of multiple cradles  138  within an automobile, permitting selective positioning of the video system  112  at the various cradle locations within the automobile  111 . 
     More particularly, the base  164  of the video system  112  is mounted to a cradle  138  formed within the ceiling  113  of the automobile  111  in a manner that permits rotation of the video housing  118  about multiple axes. The base  164  includes a first hinge  166  that facilitates rotation of the video housing  118  about an axis substantially parallel to the ceiling  113  of the automobile  111  for movement from its upward storage position (see, for example,  FIG. 12 ) to a downward use position (see, for example,  FIG. 13 ) for viewing thereof. In an effort to prevent unintentional rotation of the video system  112 , in particular, the video housing  118  and associated video monitor  116 , the first hinge  166  is provided with a safety lock  210 . In accordance with a preferred embodiment of the present invention, the safety lock  210  is a latch member shaped and dimensioned to selectively interfere with rotation of the video system  112  about the first hinge  166 . With this in mind, the safety lock  210  includes a user engagable handle  210   a  allowing a user to move the safety lock  210  from its interference position blocking rotation of the video system  112  about the first hinge  166  to a release position. Once the handle  210   a  is released, a biasing member  210   b  (for example, a spring) forces the safety lock  210  back to its interference position. The safety lock  210  will maintain the video system  112  in its storage position until such a time that a user desires to rotate the video system  112  about the first hinge  166  into its use position. In order to accomplish this rotation, the user must release the safety lock  210  by actuating the safety lock  210  and rotating the video system  112  from its storage position to its use position. 
     The base  164  further includes a second hinge  168  that permits rotation of the video housing  118  about an axis substantially perpendicular to the axis of the first hinge  166 . As such, the second hinge  168  allows for rotation of the video housing  118  in a manner that facilitates viewing of the video monitor  116  from opposite sides of the automobile  111 . The video system  112  is, therefore, designed for rotation about multiple axes and may be freely rotated to improve viewing regardless of where the video system  112  is being used. 
     In addition to the provision of a safety lock  210  associated with the first hinge  166 , the hinge structure also includes a tensioning mechanism  212 . The tensioning mechanism  212  is designed to permit free rotation of the video system  112  when desired, but apply preselected tension to the first and second hinges  166 ,  168  for controlling vibration of the video system  112  as the automobile  111  moves and vibrations are transmitted throughout the automobile  111 . In addition to preventing the transmission of vibrations to the video system  112 , the tensioning mechanism  212  also allows for controlled positioning of the video system  112  at a variety of angular orientations by simply releasing and reapplying the tensioning mechanism  212 . In accordance with a preferred embodiment of the present invention, the tensioning mechanism  212  includes a friction plate  212   a  which selectively engages the first hinge  166  to hold the video system  112  in a desired orientation. The friction plate  212   a  is attached to a handle  212   b  which allows the user to move the friction plate  212   a  between a tensioned orientation and an untensioned orientation. Similar frictional plates (not shown) are associated with the second hinge  168  for maintaining desired positioning. 
     The base  164  further includes a projecting attachment member  170  permitting selective coupling of the video system  112  within the automobile  111 . The attachment member  170  includes a fastening mechanism  171  that permits secure and convenient attachment/removal of the video system  112  from the cradle  138 . More particularly, the fastening mechanism  171  includes first and second latch members  174   a ,  174   b  shaped and dimensioned for engaging respective first and second latching recesses  176   a ,  176   b  formed on opposite sides of the cradle  138 . The first and second latch members  174   a ,  174   b  are respectively actuated by primary release buttons  178   a ,  178   b  of the first and second latch members  174   a ,  174   b  positioned at opposite ends of the video system base  164 . By pushing the release buttons  178   a ,  178   b , the first and second latch members  174   a ,  174   b  disengage from the first and second recesses  176   a ,  176   b , permitting the removal of the video system  112  from the cradle  138 . 
     Controlled release of the video system  112  from the cradle  138  is achieved through the provision of first and second safety buttons  180   a ,  180   b  which selectively lock the first and second latch members  174   a ,  174   b  in their latched position. More particularly, each of the first and second safety buttons  180   a ,  180   b  include an obstructing member  182 , which sits within the path of the first and second latch members  174   a ,  174   b  preventing movement thereof. Each of the obstructing members  182 , however, includes a release aperture  184  which aligns with a projection  186  of the respective latch members  174   a ,  174   b  when the safety buttons  184   a ,  184   b , are pressed to permit movement of the latch member  174   a ,  174   b  and release of the video system  112 . Each of the first and second safety buttons  180   a ,  180   b  is spring biased via a spring  188  to ensure they remain in their safety position unless intentionally pushed to permit movement of the first and second latch members  174   a ,  174   b.    
     Referring to  FIGS. 6 ,  7  and  8 , the appearance of the video system  312 ′ may be further enhanced by integrating the safety buttons  380   a ,  380   b  with cover plates  381   a ,  381   b  positioned at the opposite ends of the base  364 . In accordance with this embodiment, rotation of the cover plates  381   a ,  381   b  actuates the safety button  380   a ,  380   b  to permit actuation of the first and second latch members  374   a ,  374   b  and reveal the first and second release buttons  378   a ,  378   b.    
     The security of this system may be even further enhanced by linking the first and second latch members  374   a ,  374   b , requiring that the first and second latch members  374   a ,  374   b  be actuated simultaneously to permit removal of the video system  312  from the cradle  138 . As those skilled in the art will appreciate, a variety of latching structures may be employed without departing from the spirit of the present invention. 
     The cradle  138  is shaped and dimensioned for receiving and securing the video system  112  to the ceiling  113  of the automobile  111 . As those skilled in the art will certainly appreciate, similar cradles may be provided at other locations permitting use of the video system  112  at other remote locations within the same automobile or in other automobiles. 
     The cradle  138  utilized in accordance with a preferred embodiment of the present invention includes quick release electrical connections  142  for the audio input  122 , audio output  124 , video input  126 , video output  128  and power supply  130  (although one embodiment contemplates a system which connects only to a power supply). The video system  112 , and particularly, the base  164  of the video system  112 , includes mating electrical connections  144  for transmitting electricity and a/v signals between the cradle  138  and the video system  112 . In particular, when the video system  112  is mounted upon the cradle  138 , the respective electrical connections  142 ,  144  mate to provide for the transmission of power and a/v signals between the video system  112  and the cradle  138 . As those skilled in the art will certainly appreciate, other readily removable electrical connections for other purposes may also be supplied. 
     In addition to the electrical connections provided on the cradle  138 , and as was discussed above, the cradle  138  also includes a fastening mechanism  172  adapted for selective engagement with the fastening mechanism  171  of video system  112 . The fastening mechanism  172  of the cradle  138  is composed of a primary recess  193  into which the projecting attachment member  170  of the base  164  of the video system  112  may be positioned. The fastening mechanism  172  of the cradle  138  also includes the first and second latching recesses  176   a ,  176   b  that are shaped and dimensioned for selectively and securely coupling with the first and second latch members  174   a ,  174   b  of the video system base  164 . As those skilled in the art will certainly appreciate, the primary recess of the cradle and the projecting attachment member of the base may be formed in a variety of shapes so long as they are designed to provide for a secure attachment with very little play between the attached components. 
     The usefulness of the present embodiment is enhanced by the fact the cradle  138  is substantially recessed within the ceiling  113  of the automobile  111 . More particularly, each cradle  138  installed with an automobile  111  is positioned such that the face plate  192  is substantially flush with the headliner  194 , or other automobile surface, directly adjacent thereto. With this in mind, the cradle  138  is constructed with a metal mounting plate  196  directly secured to the ceiling  113  of the automobile  111  and a ceiling docking port  198  secured thereto. In accordance with a preferred embodiment, the face place  192  is formed as part of the ceiling docking port  198 . The ceiling docking port  198  includes the electrical and mechanical components discussed above which allow for the direct attachment of the video system  112  thereto. 
     Referring to  FIGS. 9 ,  10  and  11 , an alternate embodiment of the structure for attaching the video system  412  to the cradle  438  is disclosed. In accordance with this embodiment, the base  464  includes first and second projecting attachment members  470   a ,  470   b  shaped and dimensioned to engage respective first and second apertures  476   a ,  476   b  formed in the cradle  438 . The first and second projecting attachment members  470   a ,  470   b  each include an upwardly extending post  472   a ,  472   b  with a resilient spring latch  474   a ,  474   b  formed thereon. As will be discussed below in greater detail, the spring latches  474   a ,  474   b  are actuated to control passage through the respective first and second apertures  476   a ,  476   b  during installation and removal. 
     As those skilled in the art will certainly appreciate, the first and second projecting attachment members  470   a ,  470   b  will only provide limited support. As such, the video system  412  is provided with eccentric shaped first and second locking members  478   a ,  478   b  and the cradle  438  is similarly provided with eccentric shaped first and second locking apertures  480   a ,  480   b . The first and second locking members  478   a ,  478   b  are shaped to pass through respective first and second locking apertures  480   a ,  480   b  formed in the cradle when the shapes of the first and second locking members  478   a ,  478   b  and the first and second locking apertures  480   a ,  480   b  align. Once the first and second locking members  478   a ,  478   b  are passed through the first and second locking apertures  480   a ,  480   b , the first and second locking members  478   a ,  478   b  are rotated such that the shape of the first and second locking members  478   a ,  478   b  no longer align with the first and second locking apertures  480   a ,  480   b , and the video system  412  is thereby locked relative to the cradle  438 . 
     As with the prior embodiment, and referring to  FIGS. 9 ,  10  and  11 , the attachment mechanism is further enhanced with first and second safety buttons  482   a ,  482   b  associated with the first and second projecting attachment members  470   a ,  470   b . The first and second safety buttons  482   a ,  482   b  respectively control actuation of the spring latches  474   a ,  474   b  extending from the projecting attachment members  470   a ,  470   b  so that the video system  412  may not be removed until the respective safety buttons  482   a ,  482   b  are simultaneously actuated. In particular, the first and second safety buttons  482   a ,  482   b  cause controlled expansion and/or contraction of the spring latches  474   a ,  474   b  to permit or restrict passage of the spring latches  474   a ,  474   b  through the first and second apertures  476   a ,  476   b . In accordance with a preferred embodiment, the safety buttons  482   a ,  482   b  control expansion and/or contraction of the spring latches  474   a ,  474   b  by selectively drawing the spring latches  474   a ,  474   b  inward in a manner making them narrower, and thereby allowing for passage through the first and second apertures  476   a ,  476   b . When the safety buttons  482   a ,  482   b  are not actuated the spring latches  474   a ,  474   b  extend outwardly in a manner preventing passage of the spring latches  474   a ,  474   b  through the first and second apertures  476   a ,  476   b . Although a preferred technique is disclosed herein, other techniques could certainly be employed without departing from the spirit of the present invention. 
     In accordance with yet a further embodiment of the present invention, and with reference to  FIG. 9 , third and fourth safety buttons  484   a ,  484   b  are associated with the first and second locking members  478   a ,  478   b  and prevent rotation of the first and second locking members  478   a ,  478   b  until the first and second safety buttons  484   a ,  484   b  are simultaneously actuated. This embodiment also includes a tensioning mechanism  512  with a handle friction plate  512   a  and handle  512   b . Although the various embodiments for the safety buttons are shown in a single figure, those skilled in the art will appreciate they may be used together or separately without departing from the spirit of the present invention. 
     More particularly, and as will be discussed below in greater detail, the cradle is secured to a lateral beam running along the roof of the automobile. With this in mind, the orientation of the fastening mechanism components is critical to the operation and installation of the present video system. More particularly, the base  464  of the video system includes first and second projecting attachment members  470   a ,  470   b  shaped and dimensioned to engage respective first and second apertures  476   a ,  476   b  formed in the cradle  438 . The base  464  of the video system  412  also includes eccentric shaped first and second locking members  478   a ,  478   b  and the cradle  438  is similarly provided with eccentric shaped first and second locking apertures  480   a ,  480   b . Between the respective attachment members, locking members and apertures are electrical connections, which are discussed below in greater detail, linking the video system to the cradle (and the remainder of the automobile). 
     The spacing of the various fastening components relative to the electrical connections  442 ,  444  is critical to placement of the cradle  438 , and ultimately the video system  412 , along the beams, for example, the B-pillar  560  (see  FIG. 15 ), formed in the roof of an automobile. With this in mind, the inner edge  481   a ,  481   b ,  479   a ,  479   b  of the outer most fastening component, for example, the respective inner edges  481   a ,  481   b  of the locking apertures  480   a ,  480   b  or the respective inner edges  479   a ,  479   b  of the locking members  478   a ,  478   b , is preferably approximately ⅛ inch to approximately 7 inches from the respective outer edge  443   a ,  443   b ,  445   a ,  445   b  of the electrical connection  442 ,  444 , and more preferably approximately 2 inches to approximately 4 inches from the outer edge  443   a ,  443   b ,  445   a ,  445   b  of the electrical connection  442 ,  444 . It should be understand these distances are from adjacent fastening components to the outer edge of the electrical components. As such, and more particularly in accordance with a preferred embodiment, the respective inner edges  481   a ,  481   b  of the first and second locking apertures  480   a ,  480   b  are preferably approximately ⅛ inch to approximately 7 inches from the respective first and second outer edges  443   a ,  443   b  of the electrical connections  442 , and more preferably approximately 2 inches to approximately 4 inches from the respective first and second outer edges  443   a ,  443   b  of the electrical connections  442 . Similarly, the respective inner edges  479   a ,  479   b  of the locking members  478   a ,  478   b  are preferably approximately ⅛ inch to approximately 7 inches from the respective first and second outer edges  445   a ,  445   b  of the electrical connection  444 , and more preferably approximately 2 inches to approximately 4 inches from the respective first and second outer edges  445   a ,  445   b  of the electrical connection  444 . 
     As with the embodiment disclosed above with reference to  FIGS. 1 to 4 , the base  464  of the video system  412  is mounted to a cradle  438  formed within the ceiling  413  of the automobile  411  in a manner that permits rotation of the video housing  418  about multiple axes. More particularly, the base  464  includes a first hinge  466  that facilitates rotation of the video housing  418  about an axis substantially parallel to the ceiling  413  of the automobile  411  for movement from its storage (or up) position to a downward use position for viewing thereof In an effort to provide for controlled rotation of the video monitor  416  about an axis substantial parallel to the ceiling of the automobile, the first hinge  466  is provided with a rotation control mechanism  520 . In addition, to limiting movement of the video system  412 , in particular, the housing  418 , about the first hinge  466 , the rotation control mechanism  520  adjusts the storage position of the video system  412  for alignment with the ceiling  413 , in particular, the headliner  494 , of the automobile  411 . This adds to the versatility of the present system in that each automobile has a slightly different, and oftentimes drastically different, ceiling profile. As such, the present rotation control mechanism  520  allows for ready adjustment of the present video system  412  permitting optimized installation and usage of the present system. 
     With this in mind, and with reference to  FIGS. 12 ,  13  and  14 , the rotation control mechanism  520  of the first hinge  466  includes a first detent adjustment wheel  522  designed for limiting the position of the video system  412  as it is moved to its use position and a second detent adjustment wheel  524  designed for limiting the position of the video system  412  as it is moved to its storage position. Both the first detent adjustment wheel  522  and the second detent adjustment wheel  524  are in alignment with the pivot pin  526  of the first hinge  466 , providing an ideal location for control of the rotation of the video system. 
     A first detent notch  528  is associated with the first detent adjustment wheel  522 . The first detent notch  528  is shaped and dimensioned to interact with a first detent  530  extending laterally from the housing  418  and in substantial alignment for interaction with the first detent notch  528 . As such, when the housing  418  of the video system  412  is rotated about the first hinge  466  toward its downward use position, the first detent  530  will ultimately contact the first detent notch  528 , seat therein and substantially prevent further movement of the housing  418 . As those skilled in the art will certainly appreciate, it may be desirable to provide multiple viewing angles when the housing  418  is in its use position. With this in mind, the first detent adjustment wheel may be provided with multiple detent notches in which the first detent is selectively seated based upon the desired viewing angle. 
     In accordance with a preferred embodiment, the first detent  530  is biased by spring  532  toward the first detent notch  528 . Release, thereof, is provided by a button  534  linked to the first detent  530  permitting withdrawal of the first detent  530  from the first detent notch  528 . 
     With regard to the second detent adjustment wheel  524 , it includes a second detent notch  536  associated therewith. The second detent notch  536  is shaped and dimensioned to interact with a second detent  538  extending laterally from the housing  418  and in substantial alignment for interaction with the second detent notch  536 . As such, when the housing  418  of the video system  412  is rotated about the first hinge  466  toward its storage position, the second detent  538  will ultimately contact the second detent notch  536 , seat therein and substantially prevent further movement of the housing  418 . In accordance with a preferred embodiment, the second detent  538  is biased by a spring  539  toward the second detent notch  536 . Release, thereof, is provided by a button  540  linked to the second detent  538  permitting withdrawal of the second detent  538  from the second detent notch  536 . 
     The first and second adjustment wheels  522 ,  524  are secured to the first hinge  466  for movement relative thereto for ultimately controlling the position of the first and second detent notches  528 ,  536 . As such, the first and second adjustment wheels  522 ,  524  are designed to permit selective rotation relative to the first hinge  466  for adjusting the desired stop points, but are generally fixed during usage thereof such that as the housing  418  of the video system  412  is rotated about the first hinge  466 , the stop points will remain consistent and reliable. 
     In addition to the use of the rotation control mechanism  520  described above, it is contemplated a retaining mechanism, for example, a magnet system,  1721  may be used to hold the video system  1712  close to the headliner  1794  of the automobile  1711 . That is, the retaining mechanism maintains the video system  1712  adjacent the headliner  1794  and the cradle  1738  when it is in its storage position. Such a system will help in preventing shaking and other undesirable movement of the video system  1712 . In particular, and with reference to  FIGS. 48 ,  49  and  50 , the mounting bracket  1739  securing the cradle  1738  adjacent the ceiling  1713 , and ultimately the video system  1712 , is provided with a magnetically active metal portion  1797   a  that aligns with magnets  1797   b  formed in the video system  1712  when the video system  1712  is rotated to its storage position. By providing the magnetically active metal portion  1797   a  and the magnets  1797   b  in this manner, the video system  1712  is held close to the headliner  1794  of the automobile  1711  when in its storage position. 
     Referring to  FIGS. 51 and 52 , it is further contemplated other mechanisms for holding the video system close to the headliner may be employed. With reference to  FIG. 51 , the conventional magnets disclosed with reference to  FIGS. 48 ,  49  and  50 , may be replaced with electromagnets  1897   a ,  1897   b . As such, when it is sensed that the video system  1812  is rotated to within, for example, two inches of the headliner  1894 , the electromagnets  18997   a ,  1897   b  within the headliner  1894  and the video system  1812  are activated to drawn the video system  1812  toward the headliner  1894  such that it is securely stored at its storage position. 
     In accordance with an alternate embodiment, and with reference to  FIG. 52 , a latch  1999  is provided for extension from the cradle  1939  and through the headliner  1994 . The latch  1999  is designed to rotate forward to a position for engaging the video system  1912  when the video system  1912  is rotated to its storage position. 
     The base  464  further includes a second hinge  468  that permits rotation of the video housing  418  about an axis substantially perpendicular to the axis of the first hinge  466 . As such, the second hinge  468  allows for rotation of the video housing  418  in a manner that facilitates viewing of the video monitor  416  from opposite sides of the automobile  411 . The video system  412  is, therefore, designed for rotation about multiple axes and may be freely rotated to improve viewing regardless of where the video system  412  is being used. 
     In addition to the provision of a rotation control mechanism associated with the first hinge  466 , the hinge structure also includes a tensioning mechanism  512 . The tensioning mechanism  512  is designed to permit free rotation of the video system  512  when desired, but apply preselected tension to the first hinges  466  for controlling vibration of the video system  412  as the automobile moves and vibrations are transmitted throughout the automobile. In addition to preventing the transmission of vibrations to the video system  412 , the tensioning mechanism  512  also allows for controlled positioning of the video system  412  at a variety of angular orientations by simply releasing and reapplying the tensioning mechanism  512 . In accordance with a preferred embodiment of the present invention, the tensioning mechanism  512  includes a friction plate  512   a  that selectively engages the first hinge  466  to hold the video system  412  in a desired orientation. The friction plate  512   a  is attached to a handle  512   b  that allows the user to move the friction plate  512   a  between a tensioned orientation and an untensioned orientation. Similar frictional plates (not shown) are associated with the second hinge for maintaining desired positioning. As those skilled in the art will appreciate, a similar tensioning mechanism may be applied to the second hinge  468 . 
     As those skilled in the art will certainly appreciate, cradle based electronic devices are often confronted with the problem of people attempting to link non-compatible electronic products. Although this is sometimes acceptable as the products being linked are minimally compatible, this often results in problems due to non-compatible power supplies or signal processing protocols. With this in mind, the present cradle  438 /video system  412  has been developed so as to ensure only approved and compatible video systems may be used when placed within a cradle manufactured in accordance with the present invention. In particular, the cradle  438  is provided with an RF identification transceiver  542  that interacts with a similar RF identification transceiver  544  mounted within, for example, the base  464  of the video system  412 . As such, the electrical connections  442  of the cradle  438  are linked to the RF identification transceiver  542  and will remain closed until a video system  412  with an appropriate RF identification transceiver  544  is placed within the cradle  438 . 
     Controlled use of the cradle and video system may further be achieved via direct electrical communication between the cradle and the video system. In particular, and in accordance with an alternate embodiment of the present invention, the cradle and video system could be provided with respective electrical connections that permit usage only when the electrical connection is complete. 
     As with embodiment described with reference to  FIGS. 1 to 4 , the cradle  438  is shaped and dimensioned for receiving and securing the video system  412  to the ceiling of the automobile. As those skilled in the art will certainly appreciate, similar cradles may be provided at other locations permitting use of the video system  412  at other remote locations. 
     With this in mind, and with reference to  FIG. 15 , various cradles  438  may be mounted within an automobile for receiving video systems  412  in a manner permitting viewing from different locations within the automobile. For example, cradles  438  may be positioned along the same B-pillar  560  at laterally spaced positions within the automobile as shown in  FIG. 15  and/or cradles may be positioned along different B-pillars spaced along the length of the automobile. 
     In addition, it is likely people sitting on opposite sides of the vehicle will be interested in watching different videos. As such, a dual monitor system  410 ′,  410 ″,  410 ′″ is contemplated in accordance with the present invention as shown with reference to  FIGS. 16 ,  17  and  18 . The dual monitor systems  410 ′,  410 ″,  410 ′″ include respective first and second monitors  416   a ′,  416   a ″,  416   a ′″,  416   b ′,  416   b ″,  416   b ′″ and first and second video sources (not shown) mounted with first and second housings  418   a ′,  418   a ″,  418   a ′″,  418   b ′,  418   b ″,  418   b ′″. Each of the housings  418   a ′,  418   a ″,  418   a ′″,  418   b ′,  418   b ″,  418   b ′″ is linked to a single base  464 ′,  464 ″,  464 ′″ from which the first and second housings  418   a ′,  418   a ″,  418   a ′″,  418   b ′,  418   b ″,  418   b ′″ extend. Pivotal connections linking the first and second housings  418   a ′,  418   a ″,  418   a ′″,  418   b ′,  418   b ″,  418   b ′″ to the base  464 ′,  464 ″,  464 ′″ allow for rotation of the first and second housings  418   a ′,  418   a ″,  418   a ′″,  418   b ′,  418   b ″,  418   b ′″ between a storage positioned and a use position. Referring to  FIG. 18A , a dual monitor system  410 ″″ may be provided which connects with two cradles  438 ″″ mounted along the same B-pillar  560 ″″. 
     The cradle  438  includes quick release electrical connections  442  for the audio input, audio output, video input, video output and power supply (although one embodiment contemplates a system which connects only to a power supply). The video system  412 , and particularly, the base  464  of the video system  412 , includes mating electrical connections  444  for transmitting electricity and a/v signals between the cradle  438  and the video system  412 . 
     In addition to the electrical connections provided on the cradle  438 , and as was discussed above, the cradle  438  also includes a various fastening apertures  476   a ,  476   b ,  480   a ,  480   b  adapted for selective engagement with the attachment members  470   a ,  470   b ,  478   a ,  478   b  of video system  412 . 
     As with the prior embodiment, the usefulness of the present invention is enhanced by the fact that the cradle  438  is substantially recessed within the ceiling  413  of the automobile  411 . More particularly, each cradle  438  installed with an automobile  411  is positioned such that the face plate  492  is substantially flush with the headliner  494 , or other automobile surface, directly adjacent thereto. With this in mind, the cradle  438  is constructed with a metal mounting plate  496  directly secured to the ceiling  413 , more particularly, the B-pillar  560  (see  FIG. 15 ), of the automobile  411  and a ceiling docking port  498  secured thereto. The ceiling docking port  498  includes the electrical and mechanical components discussed above which allow for the direct attachment of the video system  412  thereto. 
     Regardless of which embodiment is employed, the installation of the cradle  138 ,  438  is intended to provide for an aesthetically pleasing appearance and the ceiling docking port  198 ,  498  is, therefore, provided with a face plate  192 ,  492  which substantially aligns with and is, therefore, flush with the headliner  194 ,  494  of the automobile  111 . With this in mind, the following disclosure applies to both embodiments of the video system presented above, although only the first embodiment shown in  FIGS. 1 to 4  is referenced herein. Aesthetics are further enhanced by the provision of a cover member  200 ,  200 ′,  200 ″ which may be selectively placed over the ceiling docking port  198  when it is not in use. With this in mind, the cover member  200 ,  200 ′,  200 ″ are designed to substantially conform with the color, fabric, texture etc. of the headliner  194 ,  494 . The cover member is further designed to be substantially flush with the headliner and conform with the profile thereof. 
     The cover member  200 ,  200 ′,  200 ″ is preferably frictionally engaged with docking port  198  when positioned for covering. As such, and in accordance with a preferred embodiment, the cover member  200 ,  200 ′,  200 ′ is provided with snap connections  210 ,  210 ′,  210 ″ shaped and dimensioned for engagement with the cradle  138 ,  438 . 
     As shown with reference to  FIGS. 19 ,  20  and  21 , the cover member may be a simple cover  200  (see  FIG. 19 ), a powered cover  200 ′ with various power sources  202 ′ extending therefrom (see  FIG. 20 ) or an illuminating cover  200 ″ with lights  202 ″ (see  FIG. 21 ). Where the covers require power, the cover is provided with an electrical connection  244 ′,  244 ″ allowing the cover  200 ′,  200 ″ to tap into the power supply of the cradle  438 . 
     Another cover  200 ′″ employing a rear seat, or baby, camera  202 ′″ is also contemplated as shown in  FIG. 22 . The cover  200 ′″ includes a rearwardly facing video camera  202 ′″ linked to a video monitor either integrated within the rearview mirror of the automobile or independently mounted along the dash of the automobile. By utilizing this cover  200 ′″, a driver may keep an eye on what is going on in the backseat of an automobile without constantly turning around to view the rear seats of the vehicle. As those skilled in the art will appreciate the video camera  202 ′″ is linked to the video monitor via the electrical connections  244 ′″ of the cover  200 ′″ and the cradle  138 , which are ultimately linked to the video monitor via wired or wireless means known to those skilled in the art. Similarly, and as discussed below in greater detail, the video monitor itself may be provided with a rearwardly facing video camera performing the same function as the video camera mounted within the cover. 
     The cover  200 ′″ may also be provided with a Bluetooth processor  204 ′″ programmed to interact with a variety of Bluetooth appliances that might be brought into the automobile. For example, the Bluetooth processor  204 ′″ might provide for hands-free cell phone usage, wireless Internet access for those bringing a Bluetooth enable laptop into the automobile, etc. Additional functionalities may include, for example, and not limited to, those discussed herein with regard to the use of an expansion slot. 
     The aesthetically pleasing nature of the present embodiment is further enhanced by the provision of a “free floating” video system  112 ,  412 . More particularly, and as discussed above when describing the various embodiments of the present video system  112 ,  412 , the housing  118 ,  418  with the video monitor  116 ,  416  and video source  120 ,  420  housed therein depends from the base  164 ,  464  which is then mounted to the recessed cradle  138 ,  438  formed within the ceiling of the automobile. As such, the video system  112 ,  412  depends from the ceiling integrated cradle  138 ,  438  without the need for a surrounding support structure, allowing for the provision of a self-sufficient video system  112 ,  412 . More particularly, when the video system  112 ,  412  is rotated to its storage position, it is substantially parallel and adjacent the headliner  194 ,  494  with no support structure surrounding the unattached outer perimeter, that is, the free side edges  119   a - c ,  419   a - c  to which the base  164 ,  464  is not attached, of the housing  118 ,  418 . This improves the aesthetics of the video system  112 ,  412  and does not require that a substantial portion of the headliner  194 ,  494  be covered or cut away to accommodate the installation thereof. 
     Referring to  FIGS. 23 and 24 , the “free floating” video system  612  of the present invention is further enhanced by providing selectively attachable profile members  714  to the free side edges  619   a - c  of the housing  618 . The profile members  714  are designed to substantially conform to the headliner  694  shape of the vehicle such that when the video system  612  is rotated to its storage position as shown in  FIG. 24 , the video system  612  will substantially conform with the headliner  694  in an aesthetically pleasing manner. 
     By manufacturing the profile members  714  such that they are detachably secured to the housing  618 , the video system  612  may be readily adapted to conform to the headliner  694  profile of a variety of vehicles by simply replacing the profile members  714 . Selective attachment of the profile members  714  is achieved by the provision of mating coupling members  716 ,  718  formed along the connecting surfaces of the profile members  714  and the housing  618 . While a variety of coupling members may be utilized in accordance with the present invention, the preferred coupling members will be engaging male and female latch members formed along the connecting surfaces of the profile members and the housing. 
     In addition to the aesthetically pleasing nature of a “free floating” video system, the fact that no support structure surrounds the video system allows for the ready replacement of the video system with other video systems  812   a ,  812   b ,  812   c  of differing sizes and shapes (see  FIG. 25 ). As such, a driver may choose to use various different video systems of different sizes depending upon the needs of the driver. Similarly, a dealer or installer can sell the same system at different prices depending upon the size of the monitor required by the customer. 
     Referring to the embodiment disclosed with reference to  FIGS. 26 to 29 , as a user replaces the present video system  812  with a larger video system, it might be found that the larger video system  812  blocks the driver&#39;s view as he or she looks through the rearview mirror  802  of the automobile  811 . With this in mind, the video system  812  is provided with a rearwardly facing video camera(s)  938 ,  938   a ,  938   b  and a forward facing video monitor  932  for rear view enhancement. 
     More particularly, and referring to  FIGS. 26 to 29 , the video system  812  includes a rear facing surface  934  from which the video monitor  816  discussed above displays images for viewing by passengers of the automobile  811  when the video system  812  is mounted within the ceiling  813  of the automobile  811 . The video system  812  also includes a front facing surface  936 . A forward facing video monitor  932  is provided on the front facing surface  936  for viewing alignment with the rearview mirror  802  such that the forward facing video monitor  932  may be viewed by the driver when the video system  812  is in its use position.

     As shown in  FIGS. 30 and 31 , when the video system  112  is mounted to the docking stations  1050 ,  1150 , it may be necessary to mount the video system  112  upside down when compared to its mounting within an automobile  111 . With this in mind, the video system  112  is provided with the ability to rotate to the image shown on the video monitor  116  so that the video system  112  may be used in a variety of orientations. The possible rotation of the image shown on the video monitor  116  is complemented by the multifunctional controller  160  that adjusts to the rotation of the image such that the controller  160  is calibrated to function in accordance with the orientation of the screen image. 
     With reference to  FIG. 32 , yet a further embodiment of a docking station  1250  is disclosed. This docking station  1250  is adapted for static mounting within a household, office or other locations (for example, beneath a kitchen cabinet  853 ). The docking station  1250  includes an auxiliary cradle  1238  (with electrical connections and a connecting mechanism (not shown)) shaped and dimensioned for receiving and securely supporting the video system  112  and coupling the video system  112  to power sources and a/v sources in a manner similar to the cradle  138  used in conjunction with the ceiling.

     As mentioned above, the present invention is adapted for utilization in conjunction with a dash mounted docking station. However, and as those skilled in the art will certainly appreciate, various state and local regulations prohibit the utilization of a front seat mounted video system wherein the driver of the vehicle is exposed to video entertainment. However, these state and local regulations do not prohibit a video display that provides the driver with useful information regarding the operation and performance of his or her vehicle, as well as navigation information provided with current GPS navigation systems. 
     With the foregoing in mind, the docking station  1350  disclosed with reference to  FIGS. 33 to 41  is specifically adapted for utilization and mounting upon the dash  1352  of a conventional automobile  1311 . Generally, and as will be discussed below in greater detail, the docking station  1350  is designed such that the video system  112  will provide only navigation-based displays when directed toward the driver of the automobile  1311  and will provide all video functionalities when oriented toward the passenger of the automobile  1311 . 
     More particularly, and with reference to the various figures, the docking station  1350  includes a base  1360  upon which is mounted a cradle  1338 . The base  1360  is shaped and dimensioned for secure attachment to the dash  1352  of an automobile  1311  using conventional brackets and coupling structures known to those skilled in the art. The cradle  1338  is pivotally mounted upon the base  1360  for movement about multiple axes. The cradle  1338  is shaped and dimensioned to receive and support the video system  112 . With this in mind, the cradle  1338  is provided with quick release electrical connections  1342  for the audio input  1322 , audio output  1324 , video input  1326 , video output  1328  and power supply  1330 . As discussed previously, the video system  112  similarly includes mating electrical connections  144  for transmitting electricity and AV signals between the cradle  1338  and the video system  112 . In particular, when the video system  112  is mounted upon the cradle  1338 , the respective electrical connections  144 ,  1342  mate to provide for the transmission of power and AV signals between the video system  112  and the cradle  1338 . As those skilled in the art will certainly appreciate, other readily removable electrical connections for other purposes may also be supplied if one determines they are so needed. 
     In addition to the electrical connections  1342  provided in the cradle  1338 , the cradle  1338  also includes a connecting mechanism  1362  designed for selectively retaining the video system  112  within the cradle  1338 . In accordance with a preferred embodiment of the present invention, a snap mechanism well known to those skilled in the industry will be used in selectively securing the video system within the cradle, although other coupling structure may be used without departing from the spirit of the present invention. The connecting mechanism  1362  permits ready and selective attachment of the video system  112  to the docking station  1350  while preventing vibrations and other damaging movements that may occur in an automobile. As those skilled in the art will certainly appreciate, the connecting mechanism may take a variety of forms known to those skilled in the art. 
     As discussed above, the cradle  1338  is mounted upon the base  1360  for pivotal movement relative thereto. With this in mind, a first pivotal coupling  1364  allows for forward and rearward tilting of the cradle  1338  to allow a viewer to adjust the viewing angle at which the video system  112  is oriented. 
     In addition, the base  1360  is provided with a second pivotal coupling  1366  allowing the cradle  1338  to be rotated about an axis extending substantially perpendicular to the base  1360  and providing for transverse rotation of the cradle  1338 . This rotation allows the video system  112  to be selectively oriented for viewing by either the driver or the passenger in the front seat. Movement of the cradle  1338  about this axis is controlled by a release mechanism  1368  which allows one to selectively move the cradle  1338  about the second pivotal coupling  1366  and subsequently lock it in a desired position. In accordance with a preferred embodiment of the present invention, it is contemplated a two stage release mechanism known to those skilled in the art will be used in an effort to enhance safety, although other release structures known within the art may be employed without departing from the spirit of the present invention. 
     The cradle  1338  (and ultimately the video system  112  via the electrical connections  144  and  1342 ) is electrically coupled to the second pivotal coupling  1366  via a switch  1370  so that it may signal the video system  112  as to the specific orientation of the cradle  1338 ; that is, whether the cradle  1338  is oriented for viewing by the driver or for by viewing of a passenger within the front seat. When the cradle  1338  is oriented for viewing by the driver (see  FIG. 39 ) the switch  1370  signals the video system  112  that it is oriented for viewing by the driver and the video system  112  may, therefore, only display navigation based information. Control of these instructions is provided via the switch  1370  contained within the second pivotal coupling  1366 , as well as the microprocessor  1374  controlling operation of the video system  112 . When the video system  112  is rotated (see  FIG. 40 ) for viewing by the passenger, the switch  1370  is once again activated and the video system  112  is instructed that the cradle  1338  is oriented for viewing by the passenger within the front seat of the automobile  1311 . When this instruction is provided, the video system  112  is then able to perform all functionalities associated therewith. 
     As those skilled in the art will appreciate, the functionalities may include, but are not limited to the various functions previously discussed with relation to the prior embodiments. In addition, and as with the prior embodiments, the docking station  1350  may further include a battery pack, AV inputs, AV outputs, Internet capabilities, speakers, cable input, and/or integrated satellite receivers. Those skilled in the art will also appreciate that the concepts underlying the present docking station may be employed with a system wherein the video system is integrated with the docking station, and is, therefore, designed only for use as a dash-mounted video system. 
     In addition to the fixedly mounted docking stations disclosed above, a portable docking station  1400  is disclosed with reference to  FIGS. 42 ,  43  and  44 . As with the fixedly mounted docking stations, this portable docking station  1400  includes a cradle  1430  shaped and dimensioned for receiving the video system  412  (although the present disclosure applies equally to the other video system embodiments disclosed herein) and coupling the video system  412  to power sources and a/v sources in a manner similar to the cradle used in conjunction with the ceiling. 
     The docking station  1400  includes a housing  1402  in which a cradle  1430  is positioned at a first end  1404  thereof. The cradle  1430  includes fastening structures similar to those disclosed above with reference to  FIGS. 9 ,  10  and  11  to permit selective attachment of the video system  412  thereto. The housing  1402  further includes a handle  1406  adjacent the cradle  1430  for carrying the video system  412  in a convenient and comfortable manner. 
     As with the fixedly mounted docking stations, this portable docking station  1400  includes inputs  1450 ,  1452  for connection to a power source and a/v sources. In addition, the docking station  1400  includes a battery  1455  for additional power storage for use when now hardwired power source is readily available. The docking station  1400  also includes Internet capability, speakers  1458 , cable input  1459  and/or an integrated satellite receiver  1460 . These components are linked to the video system  412  via the cradle  1430  which transmits the relevant signals to and from the video system via the respective electrical connections of the cradle and the video system. 
     A further feature of the present invention is disclosed with reference to  FIGS. 45 and 46 . In accordance with this embodiment, the potential that the video system may be utilized in a variety of orientations (for example flipped upside down) is addressed by providing a video system  1512  with a video monitor  1516  having a touch screen VGA panel  1517 . The video system  1512  also includes a touch panel control system  1560  that “flips” the graphical user interface control panel  1576  when the video system  1512  is positioned in a specific orientation. In particular, the microprocessor  1572  of the video system  1512  is provided with an orientation sensor  1574 . The orientation sensor  1574  instructs the microprocessor  1572  as to the orientation of the video system  1512 . Based upon the orientation of the video system  1512 , a graphical user interface control panel  1576  provided upon the touch screen panel  1517  of the video system  1512  orients itself for viewing and actuation by a user. For example, and with reference to  FIG. 45 , when the video system  1512  is oriented with the electrical connections  1544  facing downwardly, for example, when used in a dash docking station, the control panel  1576  is provided in a horizontal orientation properly positioned for viewing by the automobile passenger. However, when the video system  1512  is transferred and oriented from an overhead support, for example, when mounted in the ceiling of a vehicle or under a cabinet, the orientation sensor  1574  senses that the video system  1512  is oriented in this configuration and instructs the microprocessor  1572  to provide the touch screen panel  1517  with a control panel  1576  the opposite of those shown with reference to  FIG. 45  (see  FIG. 46 ). This feature obviates the need for users of the present system to read upside down instructions when the video system  1512  is provided with a touch screen mechanism. 
     Referring to  FIG. 47 , the orientation adjustment feature of the video system  1612  may also be implemented manually through the inclusion of a switching button  1674  which will instruct the microprocessor  1672  and touch panel control system  1660  to orient the control panel  1676  in a desired orientation. 
     In view of the wide range of functionalities offered in accordance with the present invention, the video monitor may be supplemented with the use of Sharp&#39;s dual screen monitor technology. In this way, one may view one video content when looking at the monitor from one angle and view another video content when viewing the video monitor from another angle. Sharp&#39;s dual screen technology provides for the simultaneously display of different information and image content in right and left views in a single unit by directionally controlling the viewing angle of the LCD. This feature makes it possible to provide information and content tailored to specific users depending on the angle at which they view the screen. Using a number of technologies, such as a parallax barrier superimposed on an ordinary TFT LCD, the LCD sends the light from the backlight into right and left directions, making it possible to show different information and visual content on the same screen at the same time depending on the viewing angle. Controlling the viewing angle in this way allows the information or visual content to be tailored to multiple users viewing the same screen. For example, one user can view the display as a PC screen for browsing the Internet or for editing video shot using a digital camera (IT) while at the same time another user watches video content such as a movie or a TV broadcast (A/V). 
     While the preferred embodiments have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, is intended to covet all modifications and alternate constructions falling within the spirit and scope of the invention as defined in the appended claims.
