       BACKGROUND OF THE INVENTION 
       [0003]    1. Field of the Invention 
         [0004]    This invention relates to multiple selectable systems integrated display and control functions units and particularly to for multiple selectable systems integrated display and control functions units electrophysiology and the like. 
         [0005]    2. Description of the Prior Art 
         [0006]    Cardiac Electrophysiology (EP) is a practice of cardiology that uses specialized catheters to map and redirect electrical pathways in the heart. This usually requires the use of other support systems such as physiologic (e.g., BP, HR and Oxygen Saturation or O2Sat) data, catheter navigation equipment (e.g., GE/Pruka, MedSystems, Whitt, Carto, ESI), Ablation modules (e.g., Cryo, EPT), ultrasound equipment e.g., (Intracardiac Echo or ICE), and radiology imaging and pacing modules. 
         [0007]    Many of these systems have their own computers, each of which has a separate monitor, keyboard and mouse configuration requiring the technologist or physician to access many different systems separately. This, of course, causes problems because this access must be done quickly. Therefore, not only must the technologist and physician concentrate on the procedure at hand, they must also deal with the technological complexities of these various systems. 
         [0008]    This situation can only lead to increased stress for the technologist and physician. Moreover, these complexities can also leads to errors, which may lead to unfortunate consequences for patients. 
       BRIEF DESCRIPTION OF THE INVENTION 
       [0009]    The instant invention overcomes these difficulties. It is a systems integrator that brings various separate systems into one keyboard, video and mouse configuration with customized viewing of the different monitors on one large screen LCD monitor. Thus, for cardiac electrophysiology, both the physician and EP technologist may control what is being viewed on the LCD monitor through touch pad technology. However, only the technologist has control of the multiple computer inputs with a “Keyboard Video Mouse” (KVM) switch located at the control station. 
         [0010]    Because facilities are different, one first establishes what equipment is used in the particular EP lab. A site visit is then arranged to discuss how the technologist and physician interact with the equipment. In some cases, new cabling and relocating equipment to a central location become part of the total solution, which includes decreasing noise and interference and reduces setup time and trouble for the technologist. The system also has recording and archiving software to provide full documentation as well as the integration of modalities in one review station. 
         [0011]    The system can also be used in other technology areas as well. In fact, any type of procedure, assembly, or similar type of process that requires individuals to view many different screens that display data of different aspects of the process can use such a system. 
         [0012]    Such systems reduce errors, increase efficiency, reduce stress and produce an overall superior result.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0023]    Note that what is discussed below is a system that is used for cardiac electrophysiology. However, the components, controls and monitors can be used in many other applications. The cardiac electrophysiology system being an example of one of them. 
         [0024]      FIG. 1  shows the system in block diagram. The system has a power strip  1  that supplies power to the units. This can be any commercial power strip that has sufficient capacity of the units employed. Six video amplifier splitters  2 - 7  are attached to the power strip. These splitters are used to accept up to six video display inputs to the system. Their purpose is to these boost the signal input up to go much longer distances with no signal quality loss. The video amplifier splitters are commercially available from several companies such as: BLACKBOX, RAM or EXTRON. 
         [0025]    The video amplifier splitters are connected Keyboard-Video-Mouse controller (KVM)  8 . This is designed to have multiple inputs and one output. In the preferred embodiment, this device is a SERVSWITCH manufactured by BLACKBOX. This item controls multiple computer inputs (keyboard, video and mouse) and sends them out to one viewable/controllable output (e.g. the main display). These devices are connected using standard cabling systems that are well known in the art. A keyboard, video screen(s) and a mouse (mice) are also connected to the KVM controller as shown. A touch pad controller  9  is designed to control at least two touch pads, such as the NXT-CV10 manufactured by AMX. In the preferred embodiment, this controller is an NI 2000 controller manufactured by AMX. This device process all the information that is sent to and from the RGB 3000 Superview or 4000 Superview video controllers (discussed below) as well as the touch panel displays. The touch pads in the exemplary system allow the technician and the physician to display desired screens at a touch of the screen. 
         [0026]    A video controller  10  that has 12 inputs and one output is connected to the touch pad controller  9 . In the preferred embodiment, the video controller  10  is an RGB 3000 SUPERVIEW or 4000 SUPERVIEW as mentioned above. The video controller provides scalable images that are then sent out to a large-scale LCD monitor (such as a SHARP PN-455). The display of the images is controlled by the two touch pads, as discussed above. 
         [0027]    All of these components are connected to a main system computer  11  that allows the users to control the system. This computer can be any generic brand of CPU because the computer hard drive is simply used to store software that is used with the video controller. 
         [0028]    Finally, the system has three serial port converters  12 - 14  that allow other peripherals to be connected to the system. 
         [0029]      FIG. 2  is a front view of a technician station  20  for this system. The technician&#39;s station has a number of computer displays  21 - 24 , keyboards  25  and  26 , mice  27  and  28 . 
         [0030]    A control box  29  and a touch pad  30 . Note that the technician&#39;s station can have other items, such as a telephone  100  for convenience. Note that the technician&#39;s station  20  that is shown is only illustrative. Any other similar workstation can be used. Moreover, the exact configuration and number of components used by the technician will vary from project to project. The various displays, computers and other devices provide the various inputs for the system. 
         [0031]    The key to the system is shown in  FIG. 3 , which is a front view of the technician&#39;s touch pad control panel  30 . The touch control pad is designed to be the main controller for the displays that are presented on the main display screen. In the preferred embodiment, this touch screen is manufactured by AMX, as discussed above. Although the touch screen is a commercial product, the display shown on the screen in the figure is custom designed as part of this system. 
         [0032]    On the screen are a number of buttons related to the various displays. As shown, these buttons are configured for a specific procedure. As noted above, however, the specific functions can be reworked for any application desired. The center of the touch screen is a representation of what is being projected on the main display screen. A set of buttons on the bottom of the screen shows a number of screen layouts that can be displayed as desired. As shown in the example, the screen shows Rad B live over Rad A live (both radiology screens showing live x-ray pictures) next to a screen showing PRUCKA live (PRUCKA is a computerized electrophysiology diagnostic monitoring system sold by General Electric. This specific screen layout is shown in the center of the lower set of screen layout buttons. 
         [0033]    The PRUCKA system is one of several commercial diagnostic monitoring systems used in such procedures. ESI stands for Endocardial Solutions, Inc, which manufactures a line of advanced cardiac mapping devices. CARTO is another system for mapping and displaying the heart. 
         [0034]    In addition to the commercial monitoring/mapping systems, conventional monitoring functions, such as Intra Cardiac Echo (ICE button) are also available. All of the displays produced by these systems can easily be displayed alone, or with any of the others, on the main display screen. As noted above, previously, these displays were limited to one display on one monitor. 
         [0035]    The left side of the touchpad shows a number of preset buttons, which can be programmed as desired. The use of preset buttons allows the physician to switch displays literally with the touch of a button. 
         [0036]    The technician&#39;s touch pad also has a set of buttons on left under the title “KVM Switch”. These buttons select which inputs are attached to the system. Only the technician has control over the KVM switch functions. 
         [0037]      FIG. 4  is a front view of the physician&#39;s touch pad control panel. As noted above, this touch pad has all of the functions discussed above without the KVM switch functions that are available to the technician. In the normal use of the invention, this touch pad is located near the operating table, which easy reach of the physician. Allowing the physician to choose the displays make the process efficient because the physician does not have to tell the technician what to display. Moreover, the possibility of error in miscommunication is eliminated when the physician can choose directly, the displays desired. 
         [0038]      FIG. 5  is a front view of the main display screen  40 . In the preferred embodiment, this screen is a flat panel display. The screen  40  is attached to a pivot arm  41  at connection  42 . This allows the screen to be pivoted in any direction for the convenience of the physician and the team involved in the procedure. This figure shows a blank screen. 
         [0039]      FIG. 6  is a front view of the main display screen showing multiple sample data displays. In this figure, the screen is displaying a sample display of a PRUKA output. Superimposed on this displays a sample of a CARTO display. 
         [0040]    This figure shows the real advantage of this system. Here, the physician up to six different displays simultaneously. Moreover, the physician can quickly select anyone of them to be enlarged or reduced. In this way, the physician can constantly monitor the patient, and procedure on one screen, which increases efficiency and reduces errors, which increases the overall safety of the procedure. 
         [0041]      FIG. 7  is a detailed block diagram showing one exemplary system configuration. Because of the size of this figure,  FIGS. 8 ,  9 , and  10 , show enlarged sections of this diagram for clarity. The sections are indicated on  FIG. 7 . 
         [0042]    Beginning on the upper left of  FIG. 7 , (shown in  FIG. 8 ), the first cabinet shows the PRUCKA MAC/LAB system and the CARTO system. Note that these systems have video outputs (e.g. V 1 , and V), keyboard connections (K) and mouse connections (M). The keyboards are run to the KVM switch (on the far right of  FIG. 8 ) Video outputs are run through video amplifiers, which are then inputted into the master video controller. The bottom of  FIG. 8  shows inputs from radiology systems. 
         [0043]      FIG. 9  shows the lower left of the diagram in  FIG. 7 . Here additional video inputs are shows (12 video inputs are provided). In addition, additional keyboards and mice are run to the KVM switch. 
         [0044]      FIG. 10  shows the right side of  FIG. 7 . Here, console monitors are fed from the main video controller. In addition, the KVM switch feeds video out to three monitors for the functions shown as well as keyboard and mouse controls as indicated. 
         [0045]    The monitor and touch pads are fed from the AMX NI-2000 data switch.
       Note that  FIG. 7  shows the design of an exemplary system. The specific components that feed into the KVM switch and controllers may be changed as desired for the particular procedure. This diagram is designed to illustrate one way of using this invention. Obviously, in other fields, the inputs would be radically different.
