Description:
BACKGROUND OF THE INVENTION 
       [0001]    Teleprompting has been at the forefront of the personal method of information dissemination for over 50 years. Like so many other technical facets of the broadcasting industry, it has experienced a flood of technological updates, making it more portable and versatile than ever before. Every teleprompter or set of teleprompters that display scrolling text to an individual has a teleprompter operating station from which the text originates. The operating station consists of a computer and accompanying equipment that allows the text to be controlled, altered, and revised by a teleprompter operator. Teleprompters have become more compact, and simpler and faster to set up over the years, yet these operating stations have changed very little beyond basic computer progression. 
         [0002]    Though basic evolutions, such as smaller, more energy-efficient laptops and the USB interface, have become part of general computing and computing in teleprompting, a teleprompter operator or tech is still required to set up and connect the same amount of components beyond the simple laptop as they did 20 years ago, including: a video signal converter; hand controller; external monitor; video signal distribution amplifier; a number of power adapters, and power strip. Many times, more additional hardware is required, because modern laptops lack many features, they sported in the past, that are still currently required for teleprompting. This interface requires additional transport space for all of these components, not to mention the needlessly-wasted time of setting up, tearing down, and resetting up of what is an unchanging configuration. 
         [0003]    Software installation for all these components can also be tedious. Due to the expense of software and hardware development, software piracy is a serious issue in the teleprompting industry. This leads to clumsy solutions, such as registration codes and USB dongles, being required for software installation, which are easily lost or misplaced. 
         [0004]    Finally, each component of the interface is also powered separately, making the powering of the station through battery power difficult and very electrically-inefficient in general. 
       BRIEF SUMMARY OF THE INVENTION 
       [0005]    The known teleprompting operating stations are not readily portable, require repetitive setup, and are not energy efficient. The present inventor has recognized what is needed to solve the aforementioned problems is to provide teleprompter operators and technicians with a computer console that takes all of the required components of a teleprompting station, and combines them into a single unit that can be easily connected to a battery power from a single source. In accordance with the invention, the portability, set up, and energy efficient use of teleprompter operating stations is enhanced by utilizing a portable teleprompting computer console containing devices or keys allowing for hand control of a teleprompter that operates off of a single power source. 
         [0006]    In particular embodiments of the invention, there may be a slightly recessed scroll wheel used for controlling the speed of the scrolling text, and four teleprompting functionality buttons that allow operators to jump to different points in the script instantly, deactivate external display, etc. With these embodiments, it may be required to insert a raised hinge block, taller than what is found on standard laptops and a screen guard extension, to allow the screen to close completely to protect all interface devices within the computer when the lid is closed. 
         [0007]    Also, in particular embodiments of the invention, the computer may have a BNC video port, the broadcast industry standard no longer found on consumer video electronics, to provide an analog video signal and a VGA monitor port to send video to an external display. 
         [0008]    Also, in particular embodiments, the power source may be 12 VDC 4 pin XLR connector that can connect the invention to wall power via a power adapter or directly to a battery power source to provide teleprompter operators and techs with an efficient and cohesive solution for long-term battery power. 
         [0009]    Also, in particular embodiments of the invention, the computer may have a laptop-style base, with bumper feet connected to the side and bottom to prevent scratching and vibration damage.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0016]    The most common type of teleprompter operating system used in the entertainment industry and its setup is depicted in  FIG. 1  and  FIG. 2 .  FIG. 1  comprises a laptop  10 , a video signal connector/converter box  11 , a teleprompter hand controller  12 , a preview monitor  13 , multiple power adapters  14 , and a power strip  15 . A number of proprietary connectors and cables connect each component to one another as necessary, including a BNC video connector  16  that connects the station to the teleprompter.  FIG. 2  illustrates how the laptop is connected to the conversion box via a USB cable, and the conversion box is then connected to the hand controller via a Serial cable and connected to both the teleprompter and the preview monitor via BNC cables. All devices are connected to their own individual power adapters, which are then connected to a power strip, which connects to and only to AC-type wall power. Said power strip is the only current method by which all electricity for the station can be consolidated into a single power source. The known teleprompting operating stations are not readily portable, require repetitive setup, and are not energy efficient. As noted above, it remained for the present inventor to recognize that making a portable teleprompting computer console would provide numerous benefits, as detailed hereinabove. 
         [0017]      FIG. 3  depicts a portable teleprompting computer console embodying the principles of the present invention  30  with all standard external human-interface components of a laptop, including a fold-down LCD screen  21 , USB ports  22 , keyboard  23 , trackpad  24 , and power/reset button  25 , that is more portable, does not require repetitive setup, and is more energy efficient than those known in the prior art. The detailed schematic of  FIG. 6  identifies these same external components as well as standard internal laptop components such as hard drive  61 , motherboard  62 , RAM  63 , and wireless fidelity internet and networking card  64 . 
         [0018]    The present inventor has discovered that it would be more time and energy efficient to have a portable teleprompting computer console that includes built-in elements of a basic teleprompter hand controller. In accordance with an advantageous feature of the invention, and as can be seen in  FIG. 1  and  FIG. 6 , the external human-interface components of particular embodiments of the present invention may include a slightly recessed scroll wheel  31  used for controlling the speed of the scrolling text on a teleprompter, and four teleprompting functionality buttons  32  that allow operators to jump to different points in the script instantly, deactivate external display, etc. With these embodiments,  FIG. 4  illustrates, from a side view, how the scroll wheel  31  extends slightly above the surface for accessibility, requiring a raised hinge block  52  taller than found on standard laptops to allow the screen to close completely, as well as a screen guard extension  53  (as also seen in  FIG. 1 ) to protect all interface devices within when the lid is closed. 
         [0019]    The present inventor has also discovered that energy efficiency of a teleprompter operating station will be enhanced by providing teleprompter operators and techs with an efficient and cohesive solution for long-term battery power. The problem is solved in this embodiment, as illustrated in  FIG. 5 , by using a 12 VDC 4 pin XLR connector  40  that can connect this embodiment of the invention to wall power via a power adapter or directly to a battery power source. 
         [0020]    The present inventor has also discovered that damage from scratching and vibration may occur when the present invention is used or transported. The problem is solved in this embodiment, as illustrated in  FIG. 4 , by placing rubber bumper feet  51  at the corners of both the bottom and the rear of this embodiment of the invention to prevent scratching and vibration damage, and by attaching a carrying strap  50  that allows this embodiment of the invention to be carried by a single hand. 
         [0021]    The present inventor has also discovered that power may be lost when the present invention is in use. The problem is solved in this embodiment, as illustrated in  FIG. 6 , by including a short-use internal battery, and a Universal Power Supply battery backup circuit  66  to control power-switching for the internal battery, for backup, in case of power loss. 
         [0022]    The foregoing merely illustrates the principle of the invention, and it will thus be appreciated that those skilled in the art will be able to devise numerous alternative arrangements that, while not shown or described herein, embody the principles of the invention and thus are within its spirit and scope.
