RELATED APPLICATIONS  
       [0001]     The present application is a continuation-in-part application of U.S. provisional patent application, Ser. No. US60/724,728, filed Oct. 7, 2005, for IMAGING MECHANISM FOR WIRELESS HANDHELD DEVICES, PORTABLE DIGITAL ASSISTANTS, AND OTHER HANDHELD COMPUTING DEVICES, by Matt Nuffort, Jeffrey Hunt, included by reference herein and for which benefit of the priority date is hereby claimed.  
         [0002]     This patent application is a continuation of the provisional patent application filed by the same inventors under the same title on 7 Oct. 2005. 
     
    
     FIELD OF THE INVENTION  
       [0003]     The present invention relates to the means of transmitting the contents of a handheld device&#39;s screen into a computer so it can be recorded or shown on a larger screen or through the Internet to enable multiple parties to view the handheld device&#39;s screen at the same time and, more particularly, to a means of accommodating virtually all different sizes and types of handheld devices in a stable manner to allow their user interfaces to be manipulated while the content of the handheld device&#39;s screen is displayed.  
       BACKGROUND OF THE INVENTION  
       [0004]     Individuals and companies developing applications and content for wirelss and other handheld devices often want to demonstrate these applications to colleagues or to potential customers. The developers often hold collaborative internal meetings, conduct demonstrations through the Internet, attend trade shows and sales meetings, where they demonstrate their new applications using their devices. A problem arises, however, when multiple people want to watch the demonstration. Handheld device displays tend to be too small for multiple individuals to view at once. A means of displaying exactly what is on the handheld device&#39;s display on a larger screen for easier viewing or through the Internet by multiple individuals at once is needed. Also, law enforcement agents and criminal prosecutors often need to capture information from a handheld device to submit as evidence or to display at a trial.  
         [0005]     There are numerous solutions in existence that address part of the problem. 1) Software solutions enable someone to connect a handheld device to a personal computer through a universal serial bus (USB) or similar connection. 2) Hardware solutions also exist that enable a person to connect hisa particular handheld device directly to a projector to project the device&#39;s display onto a larger screen. 3) Devices with cameras that take a real-time image of the handheld device&#39;s display and connect to a projector also exist. 4) Another solution for the problem is to emulate the handheld devices display in a simulation. 5) Solutions for capturing images from a handheld screen generally consist of non-commercial mechanisms involving a digital camera or video recorder.  
         [0006]     1 &amp; 2) The hardware and software solutions are device-specific. They do not work across the broad range of handheld device form factors and operating systems. Given the incredible diversity of handheld devices, it often is impractical for applications developers to focus on one particular device, and customers want to see applications that run on multiple type of devices. 3) The camera solutions in existence are often large and expensive, and they are not designed for the operation of handheld devices. Thus, they typically are not portable, or it is not practical to transport such devices, and/or they are not well suited for manipulating the handheld device&#39;s user interface while displaying an image of the device&#39;s screen. The camera devices also are not typically optimized for imaging the displays of handheld digital devices. For example, update rates for the camera must synchronize with the update rates of handheld device displays. 4) Customers often do not trust simulations, preferring instead to see new applications running real-time on actual handheld devices. They want to see exactly what the end customer will experience when using the application on an actual device. Simulations do not permit this. 5) With improvised solutions, it is difficult and time-consuming both to position the camera correctly relative to the handheld device screen, making it impractical to record all the useful evidence contained on a phone.  
         [0007]     It is therefore an object of the invention to transmit the real-time image of a handheld device&#39;s display to a computer where it can be recorded, shown on a larger screen or through the Internet for viewing by multiple individuals at once.  
         [0008]     It is another object of the invention to accommodate virtually any size or shape of handheld device and to accomodate different handheld operating systems and protocols.  
         [0009]     It is another object of the invention to fasten the handheld device to a stable base to ensure the device does not move when manipulating the device&#39;s user interface, thereby enabling a real-time demonstration without unwanted movement of the screen and facilitating rapid recording.  
         [0010]     It is another object of the invention to enable the user interface of each type of device to be accessed and manipulated easily and without interference.  
         [0011]     It is another object of the invention to be compact and portable to enable the invention to be carried easily to trade shows, sales meetings, or other events or engagements requiring travel.  
       SUMMARY OF THE INVENTION  
       [0012]     In accordance with the present invention, there is provided a foldable stand that accommodates and supports multiple types of handheld devices, a means of clamping these devices in place to enable manipulation of the device&#39;s user interface, a camera for capturing a real-time video image of the handheld device&#39;s display, a mechanism for positioning the camera, and a means of transmitting this image to a personal computer from which it can be shown on a larger screen or recorded.

         [0015]      FIG. 2  is a perspective view of a folded unit. The entire unit folds and stows into a small carrying case suitable for travel. Metal pins between the platform base and the platform leg and between the pedestal and the camera attachment enable the entire assembly to fold into a stowable unit. The pedestal collapses to reduce the size of the folded unit even further;  
         [0016]      FIG. 3  is a side view of an unit. Clearly visible are the knobs that drive the vice grips back and forth to enable the unit to securely clamp a handheld device. The camera also is clearly visible attached to the camera attachment, which in turn is attached to the pedestal with a metal pin and holds the camera above the platform base. The pedestal and thereby the camera can be raised or lowered to create the appropriate zoom level for larger or smaller handheld device screens;  
         [0017]      FIG. 4  is a perspective view of an entire unit with the camera extended. Clearly visible is the mechanism to position the camera directly over the handheld device screen. This sliding mechanism houses the camera and is adjustably fastening to the attachment to enable the camera to slide up or down to accommodate any type of handheld device;  
         [0018]      FIG. 5  is a perspective bottom view of an extended camera assembly. The camera assembly comprises a camera holder, to hold the camera module, and a cover, to fasten the camera module in place. The cover and holder are fastened to each other with screws and clamp around the attachment, which attaches to the pedestal. A ratcheting mechanism, consisting of four plastic arms that bend as they move back and forth across corrugated plastic tracks, holds the camera assembly in position; and  
         [0019]      FIG. 6  is a perspective bottom view of an open unit. It clearly shows the left and right-hand threaded rods that drive the vice grips. Left-hand-thread and right-hand-threaded nuts are inserted into the vice grips. Combined with the left-hand-threaded and right-hand-threaded rods, the vice grips move in opposite directions when the single knob is turned. This mechanism allows for automatic centering of the vice grips to ensure that the mobile device is positioned directly beneath the camera. A coupler connects the right-hand and left-hand threaded rods in the center.

       DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0021]      FIG. 1  is a perspective view of a mechanism with a camera  14  and base to attach a wireless handheld device and transmit a real-time image of the handheld device&#39;s display into a personal computer. The platform base  10  is fully adjustable to accommodate multiple sizes and shapes of wireless devices. A Knob  16  with left-hand-threaded rod  24  enables the vice grip  12  to securely fasten the handheld device to the base. A threaded left-hand-threaded nut  28  is press fit into the vice grip  12  to enable the left-hand-threaded rod  24  to translate the vice grip  12  back and forth. The camera  14  fastens to an attachment  22 , which accommodates a specific type of camera  14 . The attachment  22  is adjustably fastened to the Pedestal  18 , which is adjustable up and down with a ratcheting system, moving the camera  14  further from or closer to the handheld device&#39;s screen to accommodate different sized screens. The platform base  10  provides a stable platform for all handheld devices and enables a user to manipulate the user interface of the handheld device. The Platform Leg  20  raises the platform base  10  to an angle that enables the user to view the handheld device and manipulate the user interface.  
         [0022]      FIG. 2  is a perspective view of a folded unit. The entire unit folds and stows into a small carrying case suitable for travel. Metal pins  26  between the platform base  10  and the Platform Leg  20  and between the Pedestal  18  and the attachment  22  enable the entire assembly to fold into a stow-able unit. The Pedestal  18  collapses to reduce the size of the folded unit even further.  
         [0023]      FIG. 3  is a side view of an unit. Clearly visible are the Knob  16  that drives the vice grip  12  back and forth to enable the unit to securely clamp a handheld device. The camera  14  also is clearly visible fastened to the attachment  22 , which in turn is attached to the Pedestal  18  with a metal pin and holds the camera  14  above the platform base  10 . The Pedestal  18  and thereby the camera  14  can be raised or lowered to create the appropriate zoom level for larger or smaller handheld device screens.  
         [0024]      FIG. 4  is a perspective view of an entire unit with the camera  14  extended. Clearly visible is the mechanism to position the camera  14  directly over the handheld device screen. This sliding mechanism houses the camera  14  and is adjustably fastening to the attachment  22  to enable the camera  14  to slide up or down to accommodate any type of handheld device.  
         [0025]      FIG. 5  is a perspective bottom view of an extended camera  14  assembly. The camera  14  assembly comprises a camera  14  holder  32 , to hold the camera  14  module, and a cover  30 , to fasten the camera  14  module in place. The cover  30  and holder  32  are fastened to each other with screws and clamp around the attachment  22 , which attaches to the pedestal  18 . A ratcheting mechanism  34 , consisting of four plastic arms that bend as they move back and forth across corrugated plastic tracks, holds the camera  14  assembly in position.  
         [0026]      FIG. 6  is a perspective bottom view of an open unit. It clearly shows the left-hand-threaded rod  24  and right-hand threaded rod that drives the right and left vice grip  12 , respectively. The left-hand-threaded nut  28  and right-hand-threaded nut  38  is inserted into the right and left vice grip  12  respectively. Combined with the left-hand-threaded rod  24  and right-hand-threaded rod  42 , the left and right vice grips move in opposite directions when the single Knob  16  is turned. This mechanism allows for automatic centering of the vice grip  12  to ensure that the mobile device is positioned directly beneath the camera  14 . A coupler  40  connects the right-hand-threaded rod  42  and left-hand-threaded rod  24  in the center.
