`PRESENTATION DEVICE
`
`US 7,061472 B1
`
`2
`If a second person is to be shown a presentation, the main
`display screen can be rotated out by at least 220 degrees or
`more, so that the second person can now view the main
`display screen. The image of the main display screen is
`rotated by 180 degrees by a control device.
`The operator controls the presentation by means of the
`keyboard, a mouse or other input devices and follows the
`course of the presentation on the second display screen,
`which is arranged under the keyboard in the base unit of the
`laptop computer, whereby the keyboard does not lie on the
`base unit during the presentation, but is connected in a
`wireless manner to the computer.
`The principal advantage of this form of embodiment of
`the invention in comparison to GBM Utility Model 94
`06985 consists of the fact that no additional mechanical
`holding device is necessary for the second display screen,
`since the display Screen is integrated directly in the base unit
`of the laptop and is held there in a mechanically stable
`manner. By these measures, the costs and the total weight of
`the presentation device are considerably decreased in com
`parison to the solution according to GBMUtility Model 94
`06985. In addition, handling is improved.
`The second display Screen can be turned on and the image
`of the main display Screen can be swung out selectively by
`a switch or by keyboard input manually. However, an
`automatic turning on and rotation of the image according to
`claim 2, e.g., by arranging a device that recognizes the
`turning angle coupled to the hinge, which causes the image
`of the main display screen to rotate by 180 degrees and also
`to turn on the second image screen when a predetermined
`rotating angle of the main display Screen is present.
`According to claim3, the second display screen is smaller
`than the main display screen. This enhancement is advan
`tageous, if, e.g., a time-consuming graphic is to be shown to
`the customer, that is, e.g., an attractive and convincing
`presentation. The operator, i.e., the salesman, does not
`require this high-value presentation. He needs only to be
`able to follow the presentation and to be able to examine the
`correctness of the input of data, e.g., the personal data of the
`customer, if Such inputs are made.
`Since the second display Screen also requires a smaller
`resolution, it is more cost-favorable than the main display
`screen, whereby the total costs can be further decreased.
`The object of the invention is also solved with a device
`according to claim 4.
`The presentation device is a laptop computer with a
`keyboard that can be pulled out and a main display Screen
`that can be rotated out, which lies on the base unit of the
`laptop computer and covers the keyboard when it is pushed
`1.
`According to the invention, another display screen, which
`is also controlled by the laptop computer, is arranged under
`the keyboard in the base unit. In addition, the hinge of the
`main display screen that can be rotated out is configured in
`Such a way that the main display screen can be rotated by at
`least 220 degrees.
`The presentation device can be utilized as a conventional
`laptop computer, wherein the keyboard can be pulled out as
`desired, so that the display screen that lies under it is visible.
`This is, e.g., appropriate, if a menu is indicated on the second
`display screen, in order to be able to utilize the entire display
`Surface of the main display screen for the presentation.
`If a second person is to be shown a presentation, the main
`display Screen is rotated out by at least 220 degrees or more,
`so that the second person can now view the main display
`screen. The image of the main display Screen is rotated by
`180 degrees by a control device.

`
`The invention concerns a presentation device, which is
`primarily designed for advising customers by agents in the
`field.
`If a consultation or sales discussion is conducted at the
`customer's site, the available space is often not suitable for
`an optimal presentation, i.e., a modern presentation means,
`Such as, e.g., an overhead projector with an LC display or a
`Video projector, cannot be utilized. If, for example, insur
`ance agents or financial service providers visit customers in
`their homes, it is not possible to set up a wall for projection.
`And Such rearrangements of the room will be discouraged
`by most customers. It is thus usual to make calculations and
`diagrams on a piece of paper and then to rotate the paper
`halfway to the customer so that he can follow the additional
`written explanation. It is also possible to utilize a laptop
`computer, but this introduces problems, since both the
`salesman and the customer must both observe a relatively
`Small display screen.
`It has been shown that a presentation with a computer
`offers a number of advantages. The most varied types of life
`insurance can be calculated e.g., by means of special soft
`ware and can be presented immediately graphically, i.e.,
`easy to understand and thus convincing. Since this presen
`tation technique is being continuously further developed and
`is accepted as very convenient by the customer, there is an
`urgent need to utilize this technique also for Small presen
`tation use on site, i.e., in the customer's residence or in a
`Small office space.
`Small modern computers, such as, e.g., Small notebooks,
`due to their high computing power, in principle, offer the
`possibility of also applying programming and memory
`intensive, i.e., demanding, presentation software. Thus, a
`convincing presentation would also be possible on site at the
`customer's location, if the above-named problem of space
`limitations could be solved.
`It was proposed for this purpose, e.g., in the German
`GBM Utility Model 94 06985 to connect another flat
`40
`display screen by means of a hinge to a conventional laptop
`with flat display Screen on its upper edge, so that two
`persons sitting across from each other can each view one
`display screen. This device is suitable in principle for the
`provided case of application, but is very cumbersome in
`operation. Therefore, there is the need for a further improve
`ment of the presentation quality, for another decrease in cost,
`for a reduction in weight, or for an improved ease of
`operation.
`The object of the invention consists of creating a com
`50
`puter-supported presentation device, which makes possible a
`convincing presentation even under very limited spatial
`constraints and is easy to operate.
`The object is solved with a device according to claim 1.
`The presentation device is a conventional laptop computer
`with a removable keyboard and a main display screen that
`can be rotated out, which is applied onto the base unit of the
`laptop computer when folded in and covers the keyboard.
`According to the invention, another display screen is
`arranged under the keyboard in the base unit of the laptop
`computer, which is also connected to the laptop computer. In
`addition, the hinge of the main display Screen that can be
`rotated out is designed so that the main display Screen can
`be rotated by at least approximately 220 degrees.
`The presentation device can be utilized as a conventional
`laptop computer, whereby the keyboard can be removed as
`desired.

`The operator controls the presentation by means of the
`keyboard, a mouse or other input devices and follows the
`course of the presentation on the second display screen with
`the function of a control display screen.
`The second display Screen can be turned on and the image
`of the main display Screen can be rotated out selectively and
`manually by means of a Switch or by keyboard input.
`However, according to claim 5, an automatic turning on and
`rotation of the image is appropriate, e.g., by coupling the
`hinge with a device that recognizes a rotating angle, which
`causes the image of the main display screen to rotate by 180
`degrees and also the second display Screen is turned on when
`a predetermined rotating angle of the main display screen is
`present.
`According to claim 6, the second display Screen is a
`black-and-white display Screen. This enhancement is advan
`tageous, e.g., if a time-consuming color graphic is to be
`shown on the main display screen to the customer, which is,
`e.g., an attractive and convincing presentation. The operator,
`i.e., the salesman, does not need this high-value presenta
`tion. He only needs to be able the follow the presentation and
`to be able to check that the input is correct, if inputs are
`made, e.g., personal data of the customer.
`Since the second display Screen also requires a smaller
`resolution, it is more cost-favorable than the main display
`screen, whereby total costs can be reduced.
`According to claim 7, the keyboard can be removed as
`desired, whereby the communication with the computer is
`made by means of a wireless data interface. This option is
`then of advantage, if the presentation device, e.g., is to stand
`next to the customer.
`The object is further solved with a device according to
`claims 8 and 12.
`According to claim 8, the notebook has a main display
`screen, an integrated computer and a current Supply, as is
`usual for conventional laptops, notebooks, etc. In addition,
`a second display screen is provided, which is arranged in the
`slot for the CD-ROM drive or a slot provided particularly for
`this purpose. Since two display screens are to be controlled,
`it is clear to the person of average skill in the art that the
`electronics necessary for this purpose must also be provided.
`In addition, a control unit is provided, which rotates the
`image of the main display screen by 180 degrees for the
`presentation, so that it is correct for observation. It is clear
`to the person of average skill in the art that the hinges for this
`must be appropriately configured.
`If the notebook is to be used for the presentation, the main
`display Screen will rotate out at an angle of approximately
`270 degrees, so that a roof-like structure of approximately
`90 degrees can be set up in a stationary manner on a table.
`The observer, e.g., a customer, who sits opposite the opera
`tor, can view quite well the main display screen, and e.g.,
`follow the displayed development of his life insurance.
`The operator, e.g., the insurance salesman, can thus
`follow the input on the second display screen, and the screen
`can be driven laterally by an electric motor so that it travels
`out from a slot after a specific keyboard input or after
`actuating a Switch, so that the observer can view it. Although
`this monitoring display screen is essentially smaller than the
`main display Screen, this size is fully sufficient for moni
`toring the input.
`When the presentation has terminated, the monitoring
`display screen is again driven by an electric motor or
`manually to travel back into the slot.
`According to claim 9, the flat display screen unit can be
`easily removed from the base unit. This measure provides
`user-friendly service.
`
`40
`
`45
`
`4
`According to claim 10, the flat display unit is arranged in
`the slot for the disk drive. This form of embodiment is
`particular advantageous, since a conventional notebook need
`only be changed in its construction at the hinges and can be
`used as a conventional notebook without limitations. This
`form of embodiment is particularly cost-favorable. It is clear
`to the person of average skill in the art that the electrical plug
`connection must be designed and wired for this purpose.
`According to claim 11, the main display screen is
`designed for contact-sensitive input, whereby the operator
`can immediately recognize on the second image screen, i.e.,
`on the monitoring display screen, which position of the main
`display Screen, on which, e.g., a diagram is shown, the
`customer touches with his finger or with a pen.
`Claim 12 concerns an independent invention. A flat dis
`play Screen unit is designed Such that it can be utilized in the
`slot provided in the notebook for a CD-ROM drive, instead
`of this drive, whereby the slot, however, is arranged at the
`side edge of the notebook. The flat display screen unit
`contains a drive with an electric motor, which drives the flat
`display screen in and out, as is usual for a CD-ROM drive.
`The forms of embodiment of the invention are explained
`on the basis of the appended schematic drawings.
`FIG. 1 shows a perspective lateral view of a first form of
`embodiment of the invention for conventional use as a
`laptop.
`FIG. 2 shows a perspective lateral view of the invention
`according to FIG. 1 for use as a presentation device.

`embodiment of the invention for conventional use as a
`laptop.
`FIG. 6 shows a perspective lateral view of the invention
`according to FIG. 5 for use as a presentation device.
`FIG. 1 shows a perspective lateral view of the invention
`for conventional use as a laptop with a keyboard 1, a main
`display Screen 2, which is attached with hinges 3 to a base
`unit 4 of the laptop, so that it can be rotated out. It is also
`possible, if desired, to remove keyboard 1. The keyboard
`with separate power Supply means can be coupled in a
`wireless manner in this example by means of a conventional
`infrared interface, whereby it is up to the person with
`average skill in the art also to utilize other wireless cou
`plings.
`FIG. 2 shows the invention for use as a presentation
`device. The IR-coupled keyboard 1 is removed, so that the
`operator can view a second display screen 5. The main
`display Screen 2 is rotated out as a first display Screen, as
`shown by the double arrow. The customer thus can view
`correctly the image of the main display screen, if this image
`is rotated electronically by 180 degrees.
`FIG. 3 shows a perspective lateral view of the invention
`for conventional use as a laptop with a keyboard 1, a main
`display Screen 2, which is attached with hinges 3 to a base
`unit 4 of the laptop in Such a way that it can be rotated out.
`It is also possible, if desired, to pull out the keyboard.
`FIG. 4 shows the invention for use as a presentation
`device. Keyboard 1 is pulled out, so that the operator can
`view the second display screen 5. The main display screen
`2 is rotated out, as shown by the double arrow. The customer
`can observe the image correctly on the main display screen,
`if it is electronically rotated by 180 degrees.

`FIG. 5 shows a notebook in the closed state. It does not
`differ from a conventional notebook and has a slot 6 for the
`uptake of additional devices.
`FIG. 6 shows the notebook as a presentation device. The
`main display screen 2 is rotated out at an angle of approxi
`mately 270 degrees, so that a roof-like structure is formed,
`which is arranged in a stationary manner between the
`customer and the salesman. A slot 6, e.g., for a CD-ROM
`drive is arranged on the cross side of base unit 4 of the
`notebook. A control monitoring unit with a flat display
`screen 5 that can travel out is found in this slot 6. If the
`presentation device is to be used, the image on main display
`screen 2 is rotated electronically by 180 degrees, so that the
`customer can observe an image that is an upright-positioned
`and laterally correct image. The flat image screen 5 of a
`control monitoring unit is made to travel out by means of a
`drive with an electric motor, by means of a switch or by a
`keyboard input, and then can be viewed by the salesman for
`monitoring the input.
`The configuration of the electric-motor drive of the con
`trol monitoring unit for moving out the flat image screen 5
`can be omitted for the person of average skill in the art, since
`no inventive activity is involved. The same is true for the
`creation of the control electronics for rotating the image of
`the main display screen by 180 degrees and for the control
`of the flat display screen 5 of the control monitoring unit.
`In Summary, it is established that the Subjects of claims 1,
`4 and 8 are based on a uniform basic principle. According to
`this construction principle, the secondary image screen 5 is
`arranged underneath keyboard 1, the primary image screen
`2 can be rotated out at an angle of at least 220 degrees, and
`the image of the primary display screen 2 can be rotated by
`180 degrees.
`The configuration of the secondary image screen 5
`depends on the requirements. It is possible to select the
`secondary image screen as a small unit and/or for black
`and-white display. In this case, it serves only as an input
`monitoring means for input of letters or numbers. It is also
`possible to select a secondary display Screen of the same
`quality as the primary display Screen if, e.g., the presentation
`device will also be used as a game console, whereby two
`
`35
`
`40
`
`6
`players sit opposite one another and look only at their own
`display screens in order to play e.g., a card game.
`The invention claimed is:
`1. A presentation device, comprising:
`a base unit including operating components and having
`integrated therein a auxiliary display screen;
`a keyboard detachably received by the base unit above the
`auxiliary display screen and constructed for wireless
