Description:
FIELD OF THE INVENTION 
     The present invention relates to docking stations for mobile computing devices. 
     BACKGROUND OF THE INVENTION 
     Advances in electronics, batteries and packaging technology have led to continued increases in the number of mobile computing devices in service. These mobile computing devices often have an associated docking station that permits ready access to printers, modems, networks, and peripherals that are more humanly comfortable, amongst other connections and attributes. Though beneficial for their intended purpose, these docking stations are to some extent disadvantageous as discussed below. 
     Mobile computing devices tend to be small to facilitate efficient mobility. Docking stations tend to be configured for desktop use in which a mobile computing device is docked at the station for data transmission or for running the desktop environment with the resources of the mobile computing device. When docked at a desk top station, the screen of a mobile computing device is small, located at a relatively far distance from an operator and positioned such that an operator often has to place his or her back, neck or head in an uncomfortable position to adequately see the screen. 
     Ergonomic studies of computer-human operator interfaces have determined that a preferred monitor or screen height is that at which the top of the screen is even with the horizontal line of sight of the operator. The preferred angle of the screen is at 90 degrees to the line of sight. 
     One attempt to alleviate the undesirably low screen height of docked mobile computing devices includes providing a regular desk top monitor on a stand above the docking station. Though this may alleviate some of the problems of low-level mobile computing device screen height, the additional monitor and stand are often undesirably expensive and consumptive of space. This arrangement may also provide insufficient adjustment of screen viewing angle. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of the present invention to provide a docking station that permits adjustment of the height of the screen of a mobile computing device docked at the station. 
     It is another object of the present invention to provide such a docking station that permits adjustment of the viewing angle of the screen of a mobile computing device docked at the station. 
     It is another object of the present invention to provide such a docking station that has a low profile design, permits non-height adjusted docking and is economical, durable and user-friendly to operate. 
     It is also an object of the present invention to provide a mobile computing device for use with such a docking station. 
     These and related objects of the present invention are achieved by use of a adjustable height docking station and computing device for use therewith as disclosed herein. 
     In one embodiment, the present invention includes a docking station body having a replicated port formed in at least a first wall thereof; a receiving port electrically coupled to said replicated port; and means coupled between said docking station body and said receiving port that permits movement of said receiving port relative to said replicated port. This relative movement preferably permits an operator to adjust the height and viewing angle of a screen of a mobile computing device docked at said docking station. 
     In another embodiment, the present invention includes a docking station body having a replicated port formed in at least a first wall thereof; a receiving port electrically coupled to said replicated port; a mechanism that receives a screen of a mobile computing device to be docked at said docking station; and means coupled between said docking station body and said screen receiving mechanism that permits adjustment of the height of said screen receiving mechanism relative to said docking station body. 
     In yet another embodiment, the present invention includes a housing having processing electronics therein; a data input mechanism provided at said housing and electrically coupled to said processing electronics for input of data thereto; a monitor screen capable of displaying electronic image data that is coupled to said housing and electrically coupled to said processing electronics for displaying image data therefrom; and means for coupling said screen to said housing such that said screen can move between a closed position where a viewing side of said screen is generally flush with a top side of said housing and a fully extended position where a non-viewing side of said screen is generally flush with a bottom side of said housing. The present invention also includes a mobile computing device with a docking station port provided on the same surface of the mobile computing device as the keyboard. 
     The attainment of the foregoing and related advantages and features of the invention should be more readily apparent to those skilled in the art, after review of the following more detailed description of the invention taken together with the drawings.

     DETAILED DESCRIPTION 
     Referring to FIG. 1, a perspective view of a mobile computing device  10  for use with a docking station in accordance with the present invention is shown. Mobile computing device  10  includes a housing  11  in which are provided a microprocessor, fast access and disk memory, a battery and other conventional componentry that is known and is not shown in FIG.  1 . The screen  12  of device  10  is coupled through two double hinges discussed in more detail below with reference to FIG. 7 that permit screen  12  to rotate between a conventional closed position to a position in which the backside of screen  12  contacts the bottom  16  of the mobile computing device. Arrow A indicates the path of rotation of screen  12  towards the final folded back position of screen  12  shown in FIG.  2 . An external disk drive  13 , a keyboard  17 , a track pad  18  and a docking port  20  are also shown in the perspective of FIG.  1 . 
     Referring to FIG. 2, a perspective view of an adjustable height docking station  30  and mobile computing device  10  of FIG. 1 being mounted thereto in accordance with the present invention is shown. Docking station  30  includes a base  31  having a port replicator/connection electronics housing  32  and a stability platform  33 . Stability platform  33  is coupled through biased hinge mechanisms  36  (described in more detail below) to an adjustment arm  40 . The adjustment arm is in turn coupled through biased hinge mechanisms  36  to a receiving tray  51  that receives the mobile computing device. Receive tray  51  contains a receiving port  50  to which the docking port  20  (see FIG. 1) of a mobile computing device mounts during docking. Receiving tray  51  also contains a mobile computing device ejection mechanism  52  (discussed in more detail below). 
     Mobile computing device  10  is shown with screen  12  folded all the way back. Arrow B indicates the path the mobile computing device follows in being mounted on to receive tray  51  (such that port  20  mounts into port  50 ). The configuration of adjustable arm  40  and receiving tray  51 , and the biased pivots that interconnect them, permit both adjustment of the height and viewing angle of screen  12 . Thus the height and viewing angle of screen  12  can be adjusted to settings that are comfortable to an operator. Accordingly, docking station  30  significantly reduces unpleasant physical strain on an operator and in many cases will eliminate the need for a separate desk top monitor. 
     Referring to FIGS. 3A-3D, side views of docking station  30  in four different positions in accordance with the present invention are shown. FIG. 3A illustrates docking station  30  in the folded up position in which arm  40  sits on platform  33  and tray  51  sits on arm  30 . In this position docking station  30  has a low profile and can readily fit under a monitor stand or in another inconspicuous space. Receiving port  50  is still exposed, however, so that a mobile computing device can be docked even when receiving tray  51  is not elevated. FIG. 3B illustrates range of motion of arm  40  and tray  51 . FIG. 3C illustrates a low level position of tray  51 , while FIG. 3D illustrates an elevated position of tray  51 . 
     Referring to FIG. 4, a cross-sectional view of adjustment arm  40  and a portion of tray  51  in accordance with the present invention is shown. A flex cable  41  is provided within arm  40  for communicating electrical signals from receiving port  50  to docking station electronics within housing  32 . Cable  41  may pass through housing  32  to replicated ports  34  and/or pass through processing electronics represented by reference numeral  35 . The configuration of connections and circuitry within housing  32  will depend on the desired function of docking station  30 . For example, docking station  30  may simply be a port replicator or it may include enhancements such as extension of the PCI bus into the housing and support of PCI, ISA and PCMCIA devices. The configuration of connections and circuitry within housing  32  is generally known in the art. 
     Referring to FIG. 5, a perspective view of a connection hinge mechanism  36  in accordance with the present invention is shown. Hinge  36  includes a plastic housing  35  in which is preferably housed a plastic cylinder  34  with a metal rod  38  therein. The rod fits into a complementary socket (not shown but known) in adjustment arm  40 . Spring  42  offsets the force of gravity. Hinge mechanism  36  is known in the art. 
     Referring to FIG. 6, a cut away view of tray  51  illustrating an undocking mechanism  52  in accordance with the present invention is shown. Each undocking mechanism is pivotally mounted to the receiving tray and configured such that force in the direction of arrow C on face  53  causes movement of face  54  in the direction of arrow D. When a mobile computing device is docked, face  53  extends above the surface of tray  51 . When face  53  is depressed, for example, in response to pressure from an operator&#39;s finger, face  54  extends out of the surface of the tray, contacting the keyboard face of the mobile computing device and pushing port  20  off of receiving port  50 . 
     Referring to FIG. 7, a side view of a double hinge of mobile computing device  10  (shown in FIGS. 1 and 2) in accordance with the present invention is shown. U.S. Pat. No. 5,644,516 issued to Podwalny et al for a Portable Computer discloses several double hinge arrangements. This patent is commonly assigned to the assignee of the present application and is hereby incorporated by reference as if fully set forth herein. 
     In the embodiment of FIG. 7, double hinge  14  has a first pivot  3  that is connected to housing  11  through bracket  4  and a second pivot  5  that is connected to screen  12  by shaft  7 . If the height of the housing is X, then pivot  3  is preferably positioned at ½X so that screen  12  has the same positional relationship on both sides of housing  11 . In a preferred embodiment, pivoting bracket  4  and pivoting shaft  6  are hollow and provide a conduit for electrical wires  8  that propagate signals from processing electronics in the housing (generally represented by reference numeral  8 ) to screen  12  for display. Alternatively, a sturdy ribbon cable or the like could be connected from electronics  15  through housing  11  to screen  12 . 
     While the invention has been described in connection with specific embodiments thereof, it will be understood that it is capable of further modification, and this application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the invention and including such departures from the present disclosure as come within known or customary practice in the art to which the invention pertains and as may be applied to the essential features hereinbefore set forth, and as fall within the scope of the invention and the limits of the appended claims.
