Abstract

A dual screen presentation notebook having components that are integrally connected together to allow easy viewing of presentation materials without the users having to sit side by side craning their necks close together facing the same direction but instead can face opposite one another. When the dual screen presentation notebook is switched on, users can either (i) view identical or mirror images of the presentation materials or (ii) different images on the two monitor screens. The dual screen presentation notebook can be easily converted into a tablet computer and can also be used for other applications such as viewing electronic book, electronic photograph and images, videos, movies, etc.

Claims

1. A portable computer arrangement that includes a clamshell case containing a four component system, comprising:

a keyboard portion having a keyboard and other computer hardware;

a standard screen portion that is pivotally connected to said keyboard portion so as to pivot away from said keyboard portion and to pivot to cover said keyboard portion;

a presentation screen portion that is pivotally connected to said standard screen portion so as to pivot away from a back of said standard screen portion and to pivot to cover said back of said standard screen portion; and

a cover portion that is pivotally connected to said presentation screen portion so as to pivot away from said presentation screen portion and to pivot to cover said presentation screen portion;

wherein

said cover portion also pivots with respect to said presentation portion to a position wherein a part of said cover portion is in contact with a bottom surface of said keyboard portion; and

said part of said cover portion and said bottom surface of said keyboard portion have complimentary shapes for keeping said part of said cover portion and said bottom surface of said keyboard portion from sliding with respect to one another when in contact.

2. The computer arrangement of claim 1, further comprising:

a first lock mechanism for releaseably securing the standard screen portion to the keyboard portion;

a second lock mechanism for releaseably securing the standard screen portion to the presentation screen portion; and

a third lock mechanism for releaseably securing the presentation screen portion to the cover.

3. The computer arrangement of claim 1, wherein pivoting said presentation screen portion from said standard screen portion activates a screen associated with said presentation screen portion.

4. The computer arrangement of claim 1, further comprising a display control for causing a first image to be displayed on a first display associated with said display portion and a second image to be displayed on a second display associated with said presentation portion.

5. The computer arrangement of claim 4, wherein said first image and second image are identical.

6. The computer arrangement of claim 4, wherein said first image and said second image are different images.

7. The computer arrangement of claim 1, wherein said first image and said second image are mirror images of each other.

8. A portable computer arrangement that includes a clamshell case containing a four component system, comprising:

a keyboard portion having a keyboard and other computer hardware;

a standard screen portion that is pivotally connected to said keyboard portion so as to pivot away from said keyboard portion and to pivot to cover said keyboard portion;

a presentation screen portion that is pivotally connected to said standard screen portion so as to pivot away from a back of said standard screen portion and to pivot to cover said back of said standard screen portion; and

a cover portion that is pivotally connected to said presentation screen portion so as to pivot away from said presentation screen portion and to pivot to cover said presentation screen portion;

wherein

said cover portion also pivots with respect to said presentation portion to a position wherein a part of said cover portion is in contact with a bottom surface of said keyboard portion; and

said part of said cover portion and said bottom surface of said keyboard portion have anti-slide means for keeping said part of said cover portion and said bottom surface of said keyboard portion from sliding with respect to one another when in contact.

9. The computer arrangement of claim 8, wherein said anti-slide means comprises a non-slide surface on at least one of said cover portion and said keyboard portion.

10. A portable computer arrangement that includes a clamshell case comprising a four component system, the four components being a protective cover portion, a presentation screen portion, a standard screen portion and a keyboard portion, wherein:

(a) the protective cover portion contains two convex ridges on its front and it is fixed so as to pivot to open and close against the presentation screen portion by hinges, the cover portion having a first lock located at a front of the cover portion facing the user, and when the lock is unlocked, permits the cover to pivot from the presentation screen,

(b) the presentation screen portion being positionable so that a person can sit comfortably opposite the user and separately view the presentation being made by the user, without having to sit side by side close to the user, the presentation screen portion being fixed to pivot by hinges to open and close against the standard screen, the presentation screen having a second lock located at the back facing the customer;

(c) the standard screen portion being for the user to view presentation materials while conducting a presentation, the standard screen portion being fixed to pivot by hinges to open and close against the keyboard portion, the standard screen having a third lock located in front facing the user; and

(d) the keyboard portion having controls and hardware for a CPU built underneath it, wherein the base of the keyboard portion contains two concave grooves and when the convex ridges of the cover portion are placed into the concave grooves, so that the presentation screen portion will not slip forward during the presentation made by the user.

11. The computer arrangement of claim 10, designed to sit flat on a desk or table surface or adapted to sit at a slight angle with respect to the desk or table surface.

12. The computer arrangement of claim 10, wherein either a single or more than one computer processing unit (CPU) operates both of said displays.

13. The computer arrangement of claim 10, wherein the two monitor screens are integrally connected so that when the computer is switched on, it allow users who are sitting comfortably opposite to one another to either (i) view identical or mirror images of the presentation materials or (ii) show different images on the two monitor screens;

whereby the user may check or see information that the user does not want another user or client to see.

14. The computer arrangement of claim 13, configured so that the information that the user does not want the client to see is confidential data, while the user is making a presentation to the client that relates to the confidential data.

15. The computer arrangement of claim 13, wherein the information that the user does not want the client to see is internal cost data, while the user is making a presentation to the client on external price data.

16. The computer arrangement of claim 10, useable for applications including electronic book viewing, electronic photograph and images viewing, sharing and viewing of videos, movies, electronic photographs and images, so as to provide a comfortable and enjoyable shared experience wherein users are seated opposite one another and can view in comfort and with ease simultaneously.

17. The computer arrangement of claim 10, further comprising a surface usable as a tablet, so that the computer arrangement functions as a writing-based personal computer, without the need to use a keyboard on said keyboard portion.

18. A portable computer arrangement that includes a clamshell case containing a four component system, comprising:

a keyboard portion having a keyboard and other computer hardware;

a standard screen portion that is pivotally connected to said keyboard portion so as to pivot away from said keyboard portion and to pivot to cover said keyboard portion;

a presentation screen portion that is pivotally connected to said standard screen portion so as to pivot away from a back of said standard screen portion and to pivot to cover said back of said standard screen portion;

a cover portion that is pivotally connected to said presentation screen portion so as to pivot away from said presentation screen portion and to pivot to cover said presentation screen portion; and
