Title: Remote display and control system for telescope

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     This invention relates generally to optical systems and, more particularly, to a wearable display and remote control system operative with a personal telescope. 
     Description of the Prior Art 
     The use of conventional telescopes to view remote settings through the collection of electromagnetic radiation, such as visible light, is well known. Many of such conventional telescopes, particularly those for personal use, require the use of manual adjustment mechanisms to change things like focus and direction when being used to view targeted objects or in targeted directions. In addition, many of such conventional telescopes require a user to position themselves adjacent to the telescope and view through an integrated lens in order to see. Therefore, a problem which still exists, is that with conventional telescopes (again, particularly those for personal, in home use) remote viewing and control capability is not available or at least not feasible to implement from a cost or expertise standpoint. Thus, there remains a need for a remote display and control system for a conventional telescope which would eliminate the need for a user to position themselves adjacent to the telescope to view and adjust it. It would be helpful if such a remote display and control system for a conventional telescope included a head mounted display to allow a user to keep their hands free while viewing objects. It would be additionally desirable for such a remote display and control system for a conventional telescope to employ a stereo camera so as to feed binocular images to the wearable display. 
     The Applicant&#39;s invention described herein provides for a remote display and control system adapted to integrate to a conventional telescope and provide viewing and control features. The primary components in Applicant&#39;s remote display and control system are a conventional telescope, a controller, a camera, a wearable display and an integration system. When in operation, the remote display and control system for a conventional telescope enables the modification of a conventional telescope for use by a user positioned remotely relative to the telescope. As a result, many of the limitations imposed by prior art structures are removed. 
     SUMMARY OF THE INVENTION 
     A telescope remote display and control system for viewing objects through a telescope and controlling the telescope remotely. The telescope remote display and control system includes a wearable display, a manual controller, a camera, an mechanical adjuster, and an integration system, all of which are electrically interconnected. In the preferred embodiment, the camera, mechanical adjuster, and integration system are all attached to a target telescope and tripod assembly, while the wearable display and manual controller are positioned remotely. The integration system operates as the control hub, allowing a user to view images from the telescope with the wearable display by way of signals from the camera and control the positioning of the telescope with the manual controller through manipulation of the mechanical adjuster. 
     It is an object of this invention to provide a need for a remote display and control system for a conventional telescope which would eliminate the need for a user to position themselves adjacent to the telescope to view and adjust it. 
     It is another object of this invention to provide a remote display and control system for a conventional telescope which includes a head mounted display to allow a user to keep their hands free while viewing objects. 
     It is yet another object of this invention to provide a remote display and control system for a conventional telescope which employs a stereo camera so as to feed binocular images to the wearable display. 
     These and other objects will be apparent to one of skill in the art. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         FIG. 1  shows the components of a telescope remote display and control system in accordance with the present invention. 
     
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now to the drawings and in particular  FIG. 1 , a telescope remote display and control system  10  is shown integrated with a conventional telescope  20 , having a wearable display  11 , a manual controller  12 , a camera  13 , an mechanical adjuster  14 , and an integration system  15 . In the preferred embodiment, the wearable display  11  defines a head mounted display with at least one display screen, the manual controller  12  defines a game controller style manual user interface which can receive directional input from a user that is holding it, the mechanical adjuster  14  defines a motorized pan tilt tripod head which allows for the control of pan and tilt movement of a device (telescope in this case) to be motorized and controlled through a remote control. 
     It is appreciated that the integration system  15  defines a computer system which includes a processor, memory, and interfaces for the wearable display  11 , manual controller  12 , camera  13  and mechanical adjuster  14 . The memory would include software containing instructions that allow the processor to receive and process inputs from the camera  13  and manual controller  12  and provide usable outputs which relate to such inputs to the wearable display  11  and the mechanical adjuster  14 , thereby configuring the integration system to operate the wearable display  11 , manual controller  12 , camera  13  and mechanical adjuster  14 . 
     In the one embodiment, the camera  13  defines a stereo camera which includes at least two lenses with a separate image sensor or film frame for each lens. In such an embodiment, the lenses would be desirably placed at an intra-ocular distance from one another. In other embodiments, the camera  13  may define a 3D camera which employs a single lens configured to capture three dimensional images (such as cameras which use two LCD screens in the optical path which are used to “black out” their respective half of the lens, sending a slightly different image to the sensor), or a conventional camera which captures a 2 dimensional image 
     In one embodiment, the display screen of the head mounted display defines a single screen which shows live images from the camera  13 . In other embodiments, particularly embodiments employing a stereo or 3D capable camera  13 , the display defines a discrete screen for each eye, with each screen showing a discreet live image from the camera for each eye. 
     Shown assembled in  FIG. 1 , the camera  13  is attached to the lens of the telescope  20  and electrically connected to the integration system  15 , which is also attached to the telescope  20 . It is contemplated that the camera  13  and integration system  15  may be connected through a wire or any other suitable means to allow the transmission of electrical signals between the two (such as wireless electrical signals). The mechanical adjuster  14  is electrically connected to the integration system  15  through a wire and positioned between the tripod  21  and the telescope  20 , thereby enabling it to adjust the relative position of the telescope  20  to the tripod  21 . These components together define the telescope assembly. 
     The manual controller  12  and wearable display  11  may be positioned remotely from the telescope assembly and connected to the integration system through a wire (or other suitable means to allow the transmission of electrical signals therebetween). In this regard, a user can view images from the telescope  20  with the wearable display  11  by way of signals from the camera  13  (through the integration system  15 ) and control the positioning of the telescope  20  with the manual controller  12  through manipulation of the mechanical adjuster  14 . Notably, the manual controller  12  is handheld so a using may easily manipulate the controller  12  and input control commands to the telescope  20 . Control buttons shown on the controller  12  may be used to input control commands. The control commands available include zoom in/out, record, track and general movement of the telescope  20  across three axes of movement. Although the manual controller  12  is wired to the telescope other means of connectivity may be used such as Bluetooth or other wireless connectivity. 
     Further, the wireless connectivity may be implemented between the manual controller  12  and wearable display  11 . When operating in this wireless connectivity, images from the telescope  20  are displayed on multiple wearable displays  11  within the display and control system  10 , so users may share and view the same image. Further images may be download to storable device. 
     It is contemplated that the integration system  15 , mechanical adjuster  14 , camera  13 , manual controller  12 , and wearable display  11  may all include their own onboard power source, or may share one or more power sources housed therein or in a separate discrete electrical power module. 
     The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
