     DETAILED DESCRIPTION OF THE INVENTION 
     The present invention is now described with reference to the Figures, in which like reference numerals are used to indicate identical or functionally similar elements. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order not to unnecessarily obscure the present invention. 
     References to “one embodiment”, “an embodiment”, “an example embodiment”, etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described. 
     With reference to  FIGS. 1-3B , an embodiment of the present invention includes a support unit  30  including a stand  10  for supporting an object  1  on a surface  40 , and a joint  20 . The joint  20  may be connected to and/or connectable to the object  1  that is to be supported. The joint  20  may be manipulated to allow the stand  10  to move between different positions such that the object  1  may be supported at different support angle positions and in different support orientations. 
     The object  1  may comprise any object suitable for being supported. In one embodiment, the object  1  may comprise an object having a display  2 , such as, for example, a computer. The support unit  30  may be configured to allow the display  2  to be provided to the user in a desirable position while the object  1  is supported on the surface  40 . In one embodiment, the object  1  may comprise a computer, such as, for example, a tablet computer, in which the display is combined with one or more other computer components in a single housing unit. In one embodiment, the computer may not have a dedicated keyboard and the display  2  may comprise a touch screen such that the user may operate the display like a keyboard. Other objects which may be supported by a support unit  30  according to an embodiment of the present invention, include, but are not limited to, a laptop computer, a notebook computer, a slate computer, a monitor, a flat panel display, a sound playing device, a mobile phone, a television, a photograph display device, an electronic device, a game playing device, a projector, or any other object suitable for being supported. In one embodiment, the object  1  may not include a display  2 . 
     The support unit  30  may be adapted to support an object  1  of any size and/or shape. In one embodiment, the object  1  may be generally rectangular in shape, as shown in  FIG. 1 . The object  1  may include rounded edges and/or corners to facilitate its support on a surface. In some embodiments, the support unit  30  may be adapted to support an object of a different shape, including, but not limited to, a circular, square, oval, or polygonal shaped object. In some embodiments, the support unit  30  may be adapted to support a symmetrically or asymmetrically shaped object. 
     In one embodiment, the support unit  30  is adapted to support the object  1  on a surface  40 . The surface  40  may be a level surface, such as, for example, a desk or table. In other embodiments, the support unit  30  may be adapted to support the object  1  on a surface that is not level. 
     The support unit  30  may be configured to selectively support the object  1  on the surface  40  in a plurality of support angle positions. For example, the support unit  30  may be configured to selectively support the object  1  on the surface  40  at one or more support angles θ 1  between the object  1  and the surface  40 , as shown, for example, in  FIGS. 3A and 3B . As a result, in embodiments of the present invention in which the object  1  includes a display  2 , the support unit  30  may be configured to selectively support the object  1  on the surface  40  at one or more corresponding viewing angles θ 2  between the display  2  and a vertical plane P generally perpendicular to the surface  40 . 
     The support unit  30  may be configured to provide the display  2  to the user according to the user&#39;s needs. In this manner, the support unit  30  may be configured to selectively support the object  1  in a steep support angle position (as shown, for example, in  FIG. 3A ) and in a shallow support angle position (as shown, for example, in  FIG. 3B ). For example, a steep support angle position may be useful when the user is using the display  2  for viewing purposes and/or when the user is seated at a desk and is viewing the display  2  from a lower position. A shallow support angle position, for example, may be useful when the user is using the display  2  for input purposes (such as, for example, when the display  2  is being used as a virtual keyboard) and/or when the user is standing and is viewing the display  2  from a higher position. 
     In one embodiment, a steep support angle position may comprise an angle θ 1  between the object  1  and the surface  40  that is greater than about 45 degrees, and a shallow support angle position may comprise an angle θ 1  between the object  1  and the surface  40  that is less than about 45 degrees. In one embodiment, a steep support angle position may comprise an angle θ 1  between the object  1  and the surface  40  that is greater than about 65 degrees. In one embodiment, a shallow support angle position may comprise an angle θ 1  between the object  1  and the surface  40  that is less than about 25 degrees. The ranges of angles provided are meant to be exemplary only, and it is appreciated that the support unit  30  may be configured to support the object in other desired support angle positions. A specific exemplary embodiment will be described in more detail below. 
     The support unit  30  also may be configured to selectively support the object  1  on the surface  40  in a plurality of support orientations. For example, in embodiments in which the object  1  is generally rectangular in shape, as shown, for example, in  FIG. 1 , the support unit  30  may be adapted to provide a landscape support orientation and a portrait support orientation for the object  1 . As will be readily appreciated, generally in a portrait support orientation the height of the object  1  is greater than the width. This orientation may be useful, for example, for displaying text from pages of a book on the display  2 . Generally, in a landscape support orientation the width of the object  1  is greater than the height. This orientation may be useful, for example, for displaying an image or diagram on the display  2  that needs to be wider than the width of a portrait page. It will be appreciated that a non-rectangular and/or asymmetrical object having the same or greater height than its width nevertheless may be supported in a landscape support orientation and a portrait support orientation. For example, a non-rectangular object (such as an oval display) may be supported in a portrait support orientation by having the (vertical) height of the object greater than the (horizontal) width as it is supported. The support unit  30  may be configured to provide other support orientations, including, but not limited to, a rotated support orientation (for example, wherein only one of the corners of the object  1  shown in  FIG. 1  rests on the surface  40 ), a non-rotated support orientation, a sideways support orientation, and an upside-down support orientation. 
     The support unit  30  may be configured to selectively support the object  1  at different support angle positions and in different support orientations. In one embodiment, the support unit  30  may support the object at a first support angle position in a first support orientation, and at a second support angle position in a second support orientation. In one embodiment, the first support angle position may be the same or different from the second support angle position and the first support orientation may be the same or different from the second support orientation. For example, the support unit  30  may be configured to support the object  1  at a shallow support angle position in a landscape support orientation, and at a steep support angle position in a portrait support orientation. 
     With reference to FIGS.  1  and  3 A- 3 B, the support unit  30  may include a stand  10  operatively connected to a joint  20 , which may be connected to and/or connectable to the object  1  that is to be supported. The joint  20  may be manipulated to allow the stand to move between different support angle positions and in different support orientations. In one embodiment, the joint  20  may allow the stand  10  to rotate about an axis between multiple support angle positions and multiple support orientations. The angle of the stand  10  relative to the joint  20  may change as the stand rotates to each of the multiple positions. As discussed above, this thereby causes the stand  10  to support the object at a different angle relative to the surface  40 . 
     The joint  20  may comprise a suitable joint for being connectable to and/or connected to the object  1 . In one embodiment, as will be discussed in greater detail below, the joint  20  may comprise a ball and socket joint. Other joints, including, but not limited to, a variable linkage joint, a hinged joint, an unhinged joint, a tongue and groove joint, a flexible joint, and/or other like joints or combinations thereof may be included. 
     In one embodiment, the support unit  30  may be permanently attached to the object  1 . In one embodiment, all or a portion of the support unit  30  may be integral with the object  1 , such that all or a portion of the support unit  30  and the object  1  form a unitary structure. In another embodiment, the support unit  30  may be otherwise attachable to the object  1 . For example, the joint  20  and/or the stand  10  may be attached to the object  1  to be supported by securing means, such as, for example, a screw. Other securing means, including, but not limited to, magnets, adhesive, suction cups, locking means, latching means, or other suitable means may be used. In one embodiment, the support unit  30  may be removably securable to the object  1 . In this manner, in some embodiments the support unit  30  may be manufactured and/or sold separately from the object  1  to be supported. 
     Another embodiment of the present invention will now be described with reference to  FIGS. 4-25 , in which like reference numerals may refer to like elements. The embodiment of the present invention includes a support unit  300  including a stand  100  for supporting an object  1  on a surface  40 , and a joint  200 . The joint  200  may be connected to and/or connectable to the object  1  that is to be supported. The object  1  may or may not include a display  2 . The joint  200  is adapted to selectively move in order to allow the stand  100  to move between a plurality of support angle positions and/or support orientations for the object. 
     With reference to  FIG. 4 , in one embodiment, the joint  200  may comprise a ball and socket joint. The joint  200  may be disposed within a housing  220 , and may include a ball  210  operatively coupled to a socket  212 . The stand  100  may be connected to the ball  210 , and may include a support end  101  (as shown, for example, in  FIG. 11 ) for contacting the surface on which the object is to be supported. The socket  212  may be axially fixed within the housing  220 , but rotatable about a collar  221  formed in the housing  220 . The ball  210  may be movably restrained within the socket such that it is secured to the socket  212  but may be free to at least partially move within the socket. In one embodiment, the ball  210  may be adapted to axially translate within the socket  212  such that the stand  100  may correspondingly translate inwardly and outwardly from the housing  220 . The contour, size, and shape of the ball  210  and socket  212  are preferably adapted such that the stand may translate outwardly from the housing  220  a sufficient amount to provide the desired support angles for the object  1 . By manner of the rotation of the socket  212  and the axial translation of the ball  210  within the socket  212 , the stand  100  may be rotated and translated through a plurality of positions and may define the position (e.g., angle and orientation) at which the object  1  is supported. In this manner, the position of the support end  101  of the stand is variable. In a preferred embodiment, the socket  212 , and, correspondingly, the stand  100  may rotate 360 degrees with respect to the object  1 . Generally, the size and shape of the ball  210  and socket  212  may be configured such that the stand may achieve the desired angles and positions for supporting the object. 
     The socket  212  may be formed as part of the housing  220 , or, alternatively, may be a discrete component within the housing  220 . In one embodiment, in order to facilitate relative motion between the ball  210  and socket  212 , these components may be made of one or more suitably low-friction materials, including, but not limited to, ceramic, plastic, steel, aluminum, and the like. In one embodiment, the ball  210  may be made of plastic and the socket  212  may be made of ceramic. In one embodiment, the ball  210  and/or the socket  212  may be coated with a low-friction polymer material, such as, for example, Teflon® or the like. 
     In one embodiment, the joint  200  includes a linkage member  218  disposed within the housing  220  and operatively connected to the ball  210 . The linkage member  218  includes a first end  223  coupled to the ball  210  and a second end  225  coupled to a cam follower  216 . As shown in  FIG. 4 , the first end  223  of the linkage member  218  may be disposed on one side of the interface between the ball  210  and the socket  212 , and the second end  225  may be disposed on the other side of the interface between the ball  210  and the socket  212 . In this manner, the linkage member  218  may also keep the ball  210  operatively connected to the socket  212 . 
     The cam follower  216  is adapted to slide within a cam track  214 . In one embodiment, the cam track  214  is a channel formed within the housing  220 . In embodiments in which the support unit  300  is integral with the object  15  to be supported, the cam track  214  may be formed within the object  15  itself. For example, the cam track  214  may be formed in a housing or external surface of the object  15 . 
     As shown, for example, in  FIG. 4 , the first end  223  of the linkage member  218  may be bent to fit within a wedge area  226  formed between the stand  100  and the ball  210 . In this manner, the first end  223  of the linkage member  218  may provide sturdiness to the stand  100  and augment the support of the object  1 . The second end  225  of the linkage member  218  may be bent such that the cam follower  216  is properly disposed in the cam track  214 . In this manner, the linkage member  218  may correlate the position of the ball  210  and the socket  212  with the position of the cam follower  216  in the cam track  214 . 
     The linkage member  218  and the cam follower  216  also may facilitate rotation and translation of the ball  210  and socket  212 . As the ball  210  and socket  212  rotate, the cam follower  216  is adapted to slide within the cam track  214  such that the ball  210  and socket  212 , and correspondingly, the stand  100 , may achieve the desired support angle positions and support orientations for the object  1 . 
     The cam track  214  is shaped to receive the follower  216 , and may be configured such that the ball  210  and socket  212 , and correspondingly, the stand  100 , achieve the desired support angle positions and support orientations for the object  1 . In one embodiment, as shown in  FIG. 5 , the cam track  214  is elliptical in shape. The elliptical shape of the cam track  214  permits the cam to achieve desired positions to allow the stand  100  to achieve the desired support angle positions and support orientations for the object  1 . In one embodiment, the cam track  214  may be symmetrical in shape, and in other embodiments, the cam track  214  may be asymmetrical. In one embodiment, as shown in  FIG. 5 , the cam track  214  may be pinched at one end so as to be egg-shaped. Other shapes for the cam track  214 , including, but not limited to, a circular shape may be used as desired. The length and/or shape of the linkage member  218  may be changed depending on space constraints or the desired positions of the stand  100 , thereby causing a corresponding change in the shape of the cam track  214 . 
     In one embodiment, the linkage member  218  may comprise a suitably rigid material, such as, for example, steel, aluminum, plastic or the like such that the member  218  may provide sturdiness to the stand  100  and augment the support of the object  15 . In one embodiment, the bent shape of the linkage member  218  at the first end  223  and/or the second end  225  may also provide sturdiness to the stand  100  and augment the support of the object  1 . In one embodiment, in order to facilitate motion of the follower  216  within the cam track  214 , the follower  216  may be made of one or more suitably low-friction materials, including, but not limited to, ceramic, plastic, steel, aluminum, and the like. In one embodiment, the follower  216  and/or the cam track  214  may be coated with a low-friction polymer material, such as, for example, Teflon® or the like. 
     In one embodiment, the joint  200  includes a clamp  222  slidably engaged with a groove  224  formed within the ball  210 . The clamp  222  may be formed around a portion of the ball  210  and the socket  220  such that it is T-shaped and operatively connects the ball to the socket. The clamp  222  also may limit the movement of the ball  210  such that the ball  210  only axially translates within the socket  212  and does not rotate. As the ball  210  axially translates within the socket  212  (and, correspondingly, the stand  100  translates inwardly and outwardly from the object  1 ), the clamp  222  may slidably translate within the groove  224 . In one embodiment, the clamp  222  may be made of a suitably low-friction material similar to the ball  210 . 
     In one embodiment, the stand  100  may be formed integrally with the ball  210 . Alternatively, the stand  100  may be otherwise attached to the ball  210 . For example, the stand  100  may be attached to the ball  210  by securing means, including, but not limited to, screws, magnets, adhesive, or other suitable means. In one embodiment, the stand  100  may be removably securable to the ball  210 . 
     The stand  100  may be sized and shaped so as to adequately support the object  1  while maintaining stable contact with the surface  40 . In one embodiment, the stand  100  may be generally rectangular in shape and may have rounded edges. Other suitable shapes for the stand  100  may be used. In one embodiment, the stand  100  may be made of metal, such as, for example, stainless steel. Other materials for the stand  100 , including, but not limited to, plastic or other suitably durable material may be used. In one embodiment, the stand  100  may be made of the same material as the outer surface of the object  1  so as to provide an aesthetically uniform appearance. In embodiments in which the object  1  comprises a display device, such as, for example, a computer, the stand  100  may be made of the same material as the housing of the display device. 
     In one embodiment, all or a portion of the support unit  300  may be integral with the object  1 . For example, the housing  220  may be formed integrally with the object  1  to form a unitary structure. The housing  220  and the object  1  may be integrally formed using known manufacturing techniques. In another embodiment, the support unit  300  may be otherwise attached to the object  1 . For example, the housing  220  may be attached to the object  1  to be supported by securing means  219 , such as, for example, a screw. Other securing means  219 , including, but not limited to, magnets, suction cups, latching means, locking means, adhesive, or other suitable means may be used. In one embodiment, the support unit  300  may be removably securable to the object  1 . In this manner, in some embodiments the support unit  300  may be manufactured and/or sold separately from the object  1  to be supported. 
     As discussed above, the support unit  300  may be configured to selectively support the object  1  at one or more support angle positions and in one or more support orientations. In one embodiment of the present invention, the support unit  300  may be adapted to provide a finite number of support positions, each position corresponding to a particular support angle position and support orientation. In one embodiment, as shown in  FIG. 4 , a notch  217  may be formed in the cam track  214  at each support position, such that the follower  216  engages each notch as it rotates about the cam track. With the follower  216  engaged at a corresponding notch, the stand  100  may be secured in position and will not rotate without additional rotating force being applied. As such, the stand  100  may be sufficiently stable such that it may support the object  1 . Each notch  217  may further provide a tactile feature such that it facilitates the user finding a particular support position. In an alternative embodiment, the notch  217  may be formed in the cam follower  216  and a spring-loaded protrusion may be formed in the cam track at each support position. The protrusion may be formed such that the follower  216  is secured at each protrusion as it rotates about the cam track. In still another embodiment, the cam follower  216  may be spring-loaded to further engage each notch  217  and become locked into position. 
     As will be discussed in more detail below, in some embodiments, the stand  100  may be rotated to provide a first support angle position and support orientation such that the stand  100  extends from the joint  200  in the same direction as the top of the object  1  (or the display  2  in embodiments of the object incorporating a display). The stand  100  may then be rotated to provide a second support angle position and support orientation such that the stand  100  extends from the joint  200  in a direction opposite the top of the object  1  (or the top of the display  2  in embodiments of the object which incorporate a display). 
     As shown, for example, in  FIG. 19 , the stand  100  may include an exterior face  102  and an interior face  103 . In some embodiments, as will be discussed in more detail below, the stand  100  may be rotated such that the exterior face  102  of the stand  100  at the support end  101  may face the surface  40 , and, in some embodiments, the exterior face  102  of the stand  100  at the support end  101  may contact the surface  40 . For example, the exterior face  102  of the stand  100  at the support end  101  may face the surface  40  in an embodiment in which the stand  100  may be rotated to provide a first support angle position and support orientation such that the stand  100  extends from the joint  200  in the same direction as the top of the object  1  (or the display  2  in embodiments of the object incorporating a display). 
     Operation of a support unit  300  according to an embodiment of the present invention will now described. A user may manipulate the stand  100  to cause the joint  200  to move through a plurality of positions. In particular, the joint  200  may be adapted to allow the stand to selectively support the object  1  on the surface  40  in four support positions, each position corresponding to a particular support angle position and support orientation. 
     As shown in  FIG. 5 , the joint  200  may move to be positioned in a first support position corresponding to cam follower position  216   a . In this position, the object  1  may be supported at a steep support angle in a portrait orientation. The joint  200  may also move to be positioned in a second support position corresponding to cam follower position  216   b . In this position, the object  1  may be supported at a steep support angle in a landscape orientation. The joint  200  may also move to be positioned in a third support position corresponding to cam follower position  216   c . In this position, the object  1  may be supported at a shallow support angle in a portrait orientation. The joint  200  may also move to be positioned in a fourth support position corresponding to cam follower position  216   d . In this position, the object  1  may be supported at a shallow support angle in a landscape orientation. 
     With reference to  FIGS. 6 and 7 , the initial extraction of the stand  100  will now be described. The support unit  300  may be adapted to move between a closed position, as shown in  FIG. 6 , and an initial open position, as shown in  FIG. 7 . When the support unit  300  is in the closed position, the clamp  222  may rest at the end of the groove  224 . When the support unit  300  is moved into an initial open position, the stand  100  is moved outwardly from the housing  220 . As the stand  100  moves outwardly, the ball  210  translates within the socket  212  and the clamp  222  slides out from its resting position and moves within the groove  224 . 
     Before operation (e.g., during storage of the object  1 ) the stand  100  may be disposed in the recess  110  (as shown in  FIG. 20 ), and, as a result, may be flush with the object  1 . As shown in  FIG. 6 , in the closed position the ball  210  is positioned within the socket  212  and the clamp  222  is disposed at the end of the track  224 . The user may then access the stand  100 , and by pulling the stand outwardly from the object  1 , the user may release the stand  100  from the closed position. As a result, as shown in  FIG. 7 , the ball  210  may translate within the socket  212 , and thereby causing the clamp  222  to slide within the track  224 . The cam follower  216  is disposed within the cam track  214  and the stand  100  is ready to be rotated by the user into the desired support position. 
     With reference to  FIGS. 8-11 , the user may manipulate the joint  200  such that it is positioned in a first support position corresponding to cam follower position  216   a . In one embodiment, the user may rotate the stand  100  thereby causing the socket  212  to rotate within the housing  220 . As shown in  FIGS. 9 and 10 , as the socket  212  rotates, the cam follower  216  slides within the cam track  214 . The ball  210  translates within the socket  212 , thereby causing the clamp  222  to slide within the track  224 . In one embodiment, the first support position may be the same position as the initial open position of the stand  100 , as shown in  FIG. 7 . The user may rotate the joint  200  until the cam follower  216  is secured in the notch  217  corresponding to the desired first support position. 
     In this position, the object  1  may be supported at a steep support angle in a portrait orientation. With reference to  FIG. 11 , the object  1  is supported at a support angle θ 1  between the surface  40  and the object  1 , and a corresponding viewing angle θ 2 . In this position, the object  1  may be supported at a steep support angle in a portrait orientation. In one embodiment, the support angle θ 1  is in the range of from about 65 degrees to about 85 degrees, and the corresponding viewing angle θ 2  is in the range of from about 5 degrees to about 25 degrees. In one embodiment, the support angle θ 1  is in the range of from about 70 degrees to about 80 degrees, and the corresponding viewing angle θ 2  is in the range of from about 10 degrees to about 20 degrees. In one embodiment, the support angle θ 1  is about 75 degrees, and the corresponding viewing angle θ 2  is about 15 degrees. In this position, the stand  100  extends from the support unit  300  in a direction (as denoted by the arrow S in  FIG. 10 ) opposite the top of the object (denoted by the arrow T in  FIG. 10 ). 
     With reference to  FIGS. 12-15 , the user may manipulate the joint  200  such that it is positioned in a second support position corresponding to cam follower position  216   b . In one embodiment, the user may rotate the stand  100  thereby causing the socket  212  to rotate within the housing  220 . As shown in  FIGS. 13 and 14 , as the socket  212  rotates, the cam follower  216  slides within the cam track  214 . The ball  210  translates within the socket  212 , thereby causing the clamp  222  to slide within the track  224 . The user may rotate the joint  200  until the cam follower  216  is secured in the notch  217  corresponding to the desired second support position. 
     In this position, the object  1  may be supported at a steep support angle in a landscape orientation. With reference to  FIG. 15 , the object  1  is supported at a support angle θ 1  between the surface  40  and the object  1 , and a corresponding viewing angle θ 2 . In one embodiment, the support angle θ 1  is in the range of from about 70 degrees to about 85 degrees, and the corresponding viewing angle θ 2  is in the range of from about 5 degrees to about 20 degrees. In one embodiment, the support angle θ 1  is in the range of from about 75 degrees to about 80 degrees, and the corresponding viewing angle θ 2  is in the range of from about 10 degrees to about 15 degrees. In one embodiment, the support angle θ 1  is about 80 degrees, and the corresponding viewing angle θ 2  is about 10 degrees. In this position, the stand  100  extends from the support unit  300  in a direction (as denoted by the arrow S in  FIG. 14 ) opposite the top of the object (denoted by the arrow T in  FIG. 14 ). 
     With reference to  FIGS. 16-19 , the user may manipulate the joint  200  such that it is positioned in a third support position corresponding to cam follower position  216   c . In one embodiment, the user may rotate the stand  100  thereby causing the socket  212  to rotate within the housing  220 . As shown in  FIGS. 17 and 18 , as the socket  212  rotates, the cam follower  216  slides within the cam track  214 . The ball  210  translates within the socket  212 , thereby causing the clamp  222  to slide within the track  224 . The user may rotate the joint  200  until the cam follower  216  is secured in the notch  217  corresponding to the desired third support position. In this position, the stand  100  extends from the support unit  300  in the same direction (as denoted by the arrow S in  FIG. 18 ) as the top of the object. As a result, the stand  100  may be rotated such that the exterior face  102  of the stand  100  at the support end  101  faces and contacts the surface  40 . 
     In this position, the object  1  may be supported at a shallow support angle in a portrait orientation. With reference to  FIG. 19 , the object  1  is supported at a support angle θ 1  between the surface  40  and the object  1 , and a corresponding viewing angle θ 2 . In one embodiment, the support angle θ 1  is in the range of from about 5 degrees to about 20 degrees, and the corresponding viewing angle θ 2  is in the range of from about 70 degrees to about 85 degrees. In one embodiment, the support angle θ 1  is in the range of from about 10 degrees to about 15 degrees, and the corresponding viewing angle θ 2  is in the range of from about 75 degrees to about 80 degrees. In one embodiment, the support angle θ 1  is about 10 degrees, and the corresponding viewing angle θ 2  is about 80 degrees. 
     With reference to  FIGS. 20-23 , the user may manipulate the joint  200  such that it is positioned in a fourth support position corresponding to cam follower position  216   d . In one embodiment, the user may rotate the stand  100  thereby causing the socket  212  to rotate within the housing  220 . As shown in  FIGS. 21 and 22 , as the socket  212  rotates, the cam follower  216  slides within the cam track  214 . The ball  210  translates within the socket  212 , thereby causing the clamp  222  to slide within the track  224 . The user may rotate the joint  200  until the cam follower  216  is secured in the notch  217  corresponding to the desired fourth support position. In this position, the stand  100  extends from the support unit  300  in the same direction (as denoted by the arrow S in  FIG. 22 ) as the top of the object. As a result, as shown in  FIG. 23 , the stand  100  may be rotated such that the exterior face  102  of the stand  100  at the support end  101  faces and contacts the surface  40 . 
     In this position, the object  1  may be supported at a shallow support angle in a landscape orientation. With reference to  FIG. 23 , the object  1  is supported at a support angle θ 1  between the surface  40  and the object  1 , and a corresponding viewing angle θ 2 . In one embodiment, the support angle θ 1  is in the range of from about 5 degrees to about 20 degrees, and the corresponding viewing angle θ 2  is in the range of from about 70 degrees to about 85 degrees. In one embodiment, the support angle θ 1  is in the range of from about 10 degrees to about 15 degrees, and the corresponding viewing angle θ 2  is in the range of from about 75 degrees to about 80 degrees. In one embodiment, the support angle θ 1  is about 10 degrees, and the corresponding viewing angle θ 2  is about 80 degrees. 
     As discussed above, the stand  100  may be manipulated between a closed and open position. In one embodiment, as shown in  FIGS. 24 and 25 , a recess  110  for receiving the stand  100  while in the closed position may be formed in the object  1 . The recess may be sized and shaped appropriately to receive the stand  100  and allow the stand to be flush with the object  1  when the stand is in the closed position so as to provide an aesthetically uniform appearance. In this manner, the object also may be more easily stored or transported. In one embodiment, as shown in  FIG. 25 , the stand  100  may include a void  120  formed therein. The void  120  may facilitate user access to and outward opening of the stand  100  from the recess  110 . 
     A support unit  430  according to an alternative embodiment of the present invention will now be described with reference to  FIGS. 26-33 , in which like reference numerals may refer to like elements. As shown in  FIG. 26 , the support unit  430  may include a stand  410  for supporting an object  401  on a surface  40 , and a joint  420 . The joint  420  may be connected to and/or connectable to the object  401  that is to be supported. The joint  420  is adapted to selectively move in order to allow the stand  410  to move between a plurality of support angle positions and/or support orientations for the object. As discussed above, the object  401  may comprise any object suitable for being supported. In one embodiment, as shown in  FIG. 27 , the object  401  may comprise an object having a display  402 , such as, for example, a computer. 
     The support unit  430  may be configured to selectively support the object  401  on the surface  40  in a plurality of support angle positions, as discussed above with respect to support units  30  and  300 . For example, the support unit  430  may be configured to selectively support the object  401  on the surface  40  at one or more support angles θ 1  between the object  401  and the surface  40 , as shown, for example, in  FIGS. 28A and 28B . As a result, in embodiments of the present invention in which the object  401  includes a display  402 , the support unit  430  may be configured to selectively support the object  401  on the surface  40  at one or more corresponding viewing angles θ 2  between the display  402  and a vertical plane P generally perpendicular to the surface  40 . 
     The support unit  430  may be configured to provide the display  402  to the user according to the user&#39;s needs. In this manner, the support unit  30  may be configured to selectively support the object  401  in a steep support angle position (as shown, for example, in  FIG. 28A ) and in a shallow support angle position (as shown, for example, in  FIG. 28B ). For example, a steep support angle position may be useful when the user is using the display  402  for viewing purposes and/or when the user is seated at a desk and is viewing the display  402  from a lower position. A shallow support angle position, for example, may be useful when the user is using the display  402  for input purposes (such as, for example, when the display  402  is being used as a virtual keyboard) and/or when the user is standing and is viewing the display  402  from a higher position. 
     In one embodiment, a steep support angle position may comprise an angle θ 1  between the object  401  and the surface  40  that is greater than about 45 degrees, and a shallow support angle position may comprise an angle θ 1  between the object  401  and the surface  40  that is less than about 45 degrees. In one embodiment, a steep support angle position may comprise an angle θ 1  between the object  401  and the surface  40  that is greater than about 65 degrees. In one embodiment, a shallow support angle position may comprise an angle θ 1  between the object  401  and the surface  40  that is less than about 25 degrees. The ranges of angles provided are meant to be exemplary only, and it is appreciated that the support unit  430  may be configured to support the object in other desired support angle positions. 
     With reference to  FIGS. 29 and 30 , in one embodiment, the joint  420  may comprise a linkage assembly  440  pivotally connected to the stand  410  and operatively connected to a linkage base  444 , which is adapted to rotate within a housing  454 . By rotating the linkage base  444  and pivoting the linkage assembly  440 , the stand  410  may be rotated and pivoted through a plurality of positions and may define the position (e.g., angle and orientation) at which the object  401  is supported. 
     The linkage assembly  440  may be disposed within the housing  454  and may include a first linkage member  441  and a second linkage member  442 . During operation, the first linkage member  441  and the second linkage member  442  may extend through an opening  456  in the linkage base  444 . The first linkage member  441  and the second linkage member  442  are sized to provide the desired angles and positions for supporting the object  401 . In one embodiment, the first linkage member  441  may have a different length than the second linkage member  442 . For example, as shown in  FIG. 29 , the first linkage member  441  may be shorter than the second linkage member  442 . In other embodiments, the first linkage member  441  and the second linkage member  442  may be the same length, or the first linkage member  441  may be longer than the second linkage member  442 . 
     In one embodiment, at their upper ends the first and second linkage members  441  and  442  may be attached to hubs  411  formed on the stand  410 . In one embodiment, the first and second linkage members  441  and  442  may be attached to hubs  411  by upper pins  443 . The upper pins  443  may act as pivot points such that the stand  410  may rotate about the upper pins  443  inwardly and outwardly from the object  401 . In other embodiments, the first and second linkage members  441  and  442  may be attached to the hubs  411  by other means, such as, for example, screws or other means that allow rotation of the stand  410  about the pivot point. 
     As shown in  FIGS. 30 and 31 , in one embodiment the first linkage member  441  and the second linkage member  442  may rotate at their lower ends about lower pins  446  and  447 , respectively. The first linkage member  441  may be attached at its lower end to a plate  452 , which is fixed within the housing  454 , by the lower pin  446 . As with the upper pin  443 , the lower pin  446  may act as a pivot point. As the first linkage member  441  rotates about the lower pin  446 , the stand  410  may correspondingly rotate about the upper pin  443 . The second linkage member  442  may be rotatably attached to a lower hub  448  by lower pin  447 . As the second linkage member  442  rotates about the lower pin  447 , the stand  410  may correspondingly rotate about the upper pin  443 . 
     A cam follower  449  may be connected to the lower hub  448 . In one embodiment, the cam follower may be part of the hub  448  so as to form a unitary structure. The cam follower  449  is adapted to slide within a cam track  450 . In one embodiment, as shown in  FIGS. 31-33 , the cam track  450  may be a channel formed within the housing  454 . In embodiments in which the support unit  430  is integral with the object  401  to be supported, the cam track  450  may be formed within the object  401  itself. For example, the cam track  450  may be formed in a housing or external surface of the object  401 . Similarly, the housing  454  may form a part of the object  401 . In one embodiment, the housing  454 , and thereby all or a portion of the support unit  430 , may be attachable to the object  401  by securing means  455 , such as, for example, a screw. For example, the housing  454  may be attached to an internal surface of the object  401 , as shown in  FIG. 30 . Other securing means  455 , including, but not limited to, magnets, adhesive, suction cups, locking means, latching means, or other suitable means may be used. In one embodiment, the support unit  430  may be removably securable to the object  401 . In this manner, in some embodiments the support unit  430  may be manufactured and/or sold separately from the object  401  to be supported. 
     The support unit  430  may be configured to selectively support the object  401  at one or more support angle positions and in one or more support orientations. In one embodiment of the present invention, the support unit  430  may be adapted to provide a finite number of support positions, each position corresponding to a particular support angle position and support orientation. In one embodiment, a notch  451  may be formed in the cam track  450  at each support position, such that the cam follower  449  engages each notch  451  as it rotates about the cam track. With the cam follower  449  engaged at a corresponding notch, the stand  410  may be secured in that position and will not rotate without additional rotating force being applied. As such, the stand  410  may be sufficiently stable such that it may support the object  401 . 
     As the user rotates the stand  410 , and, correspondingly, the cam follower  449  within the cam track  450 , the user may “feel” when follower reaches a notch  451 . As such, each notch  451  may further provide a tactile feature such that it facilitates the user finding a particular support position. In an alternative embodiment, the notch  451  may be formed in the cam follower  449  and a spring-loaded protrusion may be formed in the cam track at each support position. The protrusion may be formed such that the follower  449  is secured at each protrusion as it rotates about the cam track. In still another embodiment, the cam follower  449  may be spring-loaded to further engage each notch  451  and become locked into position. 
     In one embodiment, the linkage base  444  is adapted to rotate 360 degrees. In other embodiments, the linkage base  444  may be adapted to rotate less than 360 degrees. In one embodiment, the joint  420  may include a bushing  445  disposed within the housing  454 . The linkage base  444  may be disposed such that it may freely rotate within the bushing  445 . The bushing  445  may be made of a low friction material, such as, for example, plastic or the like to facilitate rotation of the linkage base  444 . 
     With reference to  FIG. 32 , the initial extraction of the stand  410  will now be described. The support unit  430  may be adapted to move between a closed position, as shown in  FIG. 32 , and an initial open position, as shown in  FIG. 31 . Before operation (e.g., during storage of the object  401 ) the stand  410  may be disposed in the recess  412  (as shown, for example, in  FIG. 30 ), and, as a result, may be flush with the object  401 . When the support unit  430  is in the closed position, the first linkage member  441  and the second linkage member  442  may be pivoted about the lower pins  446  and  447 , respectively, such that the stand is collapsed and disposed against the object  401 . In this position, the first linkage member  441  and the second linkage member  442  may be collapsed within the housing  454  such that the linkage members do not extend through the opening  456  in the linkage base  444 . 
     When the support unit  430  is moved into an initial open position, as shown in  FIG. 31 , the stand  410  is moved outwardly from the object  401 . As the stand  410  moves outwardly, the first linkage member  441  rotates about the lower pin  446  and the second linkage member  442  rotates about the lower pin  447 . The lower pin  447  may be adapted to slide within a groove  453  formed between the plate  452  and the linkage base  444 , as shown in  FIGS. 30 and 31 . As the lower pin  447  slides within the groove  453 , the cam follower  449  slides within the cam track  450 . When the stand  410  is in the initial open position, the lower pin  447  is at the end of the groove  453 , as shown in  FIGS. 31 and 33 . The stand  410  may now be rotated to its desired position. 
     As the stand  410  rotates, the linkage base  444  rotates within the bushing  445 , thereby rotating the linkage assembly  440 . As a result, the cam follower  449  slides within the cam track  450 . The stand  410  may be rotated until it is secured in the notch  451  corresponding to the desired support angle position and orientation. 
     While the invention has been described in terms of several embodiments, there are alterations, permutations, and equivalents, which fall within the scope of this invention. It is therefore intended that the following appended claims be interpreted as including all such alterations, permutations, and equivalents as fall with the true spirit and scope of the present invention.
