`NOTEBOOK-TYPE INFORMATION PROCESSING APPARATUS AND THE CONTROL METHOD THEREOF
`
`
`(57) ABSTRACT
`OBJECTIVE: To improve the usability of a notebook-type personal computer in situations where the user operates
`the notebook-type personal computer while holding it with his or her hand in the state in which the panel is open.
`
`MEANS FOR RESOLUTION: The top face of the main body 1 is
`opened or closed with a display panel that is attached to said main
`body 1 in such a way that the display panel can be rotatable by 360
`degrees about the rear side of said main body. The angle of rotation
`of the display panel as detected by the panel sensor 14 is sent to
`the monitoring system 13. When the angle as detected by the panel
`sensor 14 reaches any of the preset rotation angles registered in the
`system-control setting part 12, the monitoring system 13 instructs
`that the PC system 11 execute the system control corresponding to
`the preset rotation angle concerned as registered in the system-
`control setting part 12. In particular, the system control is pre-
`registered, in the system-control setting part 12, so as to prohibit
`input from any devices other than the touch panel (which is
`disposed on the display panel) when the rotation angle of the
`display panel is 360 degrees.

`

`PRIOR ART
`
` With a notebook-type personal computer that has a touch panel provided on the display
`panel, in situations where the touch panel is intended for use in insurance-related services
`or collection of bills, etc., at customers’ locations, the user is often required to operate the

`
`[0014]
`
`EMBODIMENTS OF THE INVENTION
`
` The following is an explanation of embodiments of the invention with reference to
`drawings:
`
`[0015] Figure 1 shows a perspective view of the notebook-type personal computer
`according to an embodiment of the present invention.
`
`Lenovo EX-1014, Page 012
`IPR2021-00786 (Lenovo Inc. v. LiTL LLC.)
`
`

`

`[0016] With the notebook-type personal computer according to the present embodiment,
`the top surface of the main body 1 is opened or closed with a display panel 2, which is
`mounted in such a way that it can rotate about the rear side of the main body 1. The top
`surface of the main body 1 acts as the operation surface provided with a keyboard 4 and a
`track board 5. A liquid-crystal display panel 3 with a touch panel is provided on the surface
`of the display panel 2 that faces the operation surface of the main body 1. Figure 1 illustrates
`the state in which the display panel 2 is half-opened. The display panel 2 can rotate from
`the closed state in which the surface of the liquid-crystal panel 3 coincides with the
`operation surface of the main body 1 (i.e., the state in which the angel of rotation relative
`to the operation surface is 0 degree) up to the state in which the flip side of the liquid-
`crystal panel 3 on the display panel 2 coincides with the flip side of the operation surface of
`the main body 1 (i.e., the state in which the angel of rotation is 360 degrees).
`
`[0017] The Figures 2 and 3 show perspective views of the state in which the display panel 2
`is rotated by 360 degrees relative to the operation surface — as viewed from the display-
`panel-2 side and as viewed from the main-body-1 side, respectively.
`
`[0018] Figure 4 shows a perspective view that illustrates a state in which a person operates
`the touch panel with a stylus pen 9 while holding, with his or her hand, the notebook-type
`personal computer in the state the display panel 2 is rotated by 360 degrees, so as to show
`the liquid-crystal panel 3 to another person. In the example shown in the figure, the display
`panel 2 is rotated by 360 degrees and thus in the fully opened state; that is, the main body
`1 and the display panel 2 are folded in reverse of the normal closed state. Accordingly, the
`usability dramatically improves in the fully opened-state as compared with the half-open
`state shown in Figure 1. Hence, it becomes possible to operate the touch panel with the
`same level of convenience as that offered by PDAs.
`
`[0019] The notebook-type personal computer according to the present embodiment
`enables system control (e.g., input control, launching of applications, OS switchover, etc.)
`in accordance with the angle of rotation of the display panel 2. Figure 5 shows a block
`diagram that illustrates a system configuration that enables the execution of such control.
`
`[0020] The panel sensor 14 detects the angle of rotation of the display panel 2 relative to
`the operation surface of the main body 1. The PC system 11 represents a member that
`comprises a CPU, etc., which processes programs in the notebook-type personal computer.
`As shown in Figure 6, preset rotation angles and the types of system control corresponding
`to the preset rotation angles are registered in the system-control setting part 12 in advance.
`
`[0021] The rotation angle as detected by the panel sensor 14 is sent to the monitoring
`system 13; and then the monitoring system 13 monitors whether the angle as detected by
`the panel sensor 14 matches with any of the preset rotation angles that are registered in
`
`Lenovo EX-1014, Page 013
`IPR2021-00786 (Lenovo Inc. v. LiTL LLC.)
`
`

`

`the system-control setting part 12. When the angle as detected by the panel sensor 14
`reaches any of the preset angles, the system monitoring part 13 instructs that the PC system
`11 execute the system control corresponding to the preset angle as registered in the
`system-control setting part 12.
`
`[0022] Next is an explanation of the usage method and operation of the present
`embodiment:
`
`[0023] A keyboard 4 or the like is used to pre-register, in the system-control setting part 12,
`preset rotation angles and system-control identification names, etc., which correspond to
`the respective preset rotation angles. In the example shown in Figure 6, 0 degree, 180
`degrees, and 360 degrees are registered as the preset rotation angles; and commands, such
`as "sleep and turn off display power," "invert screen, and automatically launch an
`application," "prohibit input from devices other than the touch panel," "launch another
`application," and "switch OS" are registered as the system control corresponding to the
`preset rotation angles. Figure 6 is herein presented by way of example; that is, it is also
`possible to configure the system control with different settings other than those shown in
`Figure 6. Or, it is also possible to elect not to register any setting. Nevertheless, the example
`shown in Figure 6 shall be used hereafter to illustrate the present embodiment.
`
`[0024] When the user opens the display panel 2, turns on the power, and opens the display
`panel 2 wider until the rotation angle reaches 180 degrees (the rotation angle 180 degrees
`represents the state in which the display panel 2 is held flat on the same plane as that of
`the main body 1; provided that the rotation angle of the display panel 2 in the closed state
`is 0 degree), the monitoring system 13 instructs that the PC system 11 execute the system
`control so as to "invert screen and automatically launch an application" according to the
`contents registered in the system-control setting part 12.
`
`[0025] When the display panel 2 is unfolded further until the rotation angle reaches 360
`degrees (i.e., in the state shown in Figure 2 and Figure 3), the monitoring system 13 instructs
`that the PC system 11 execute the system control so as to "prohibit input from devices other
`than the touch panel," "automatically activate an application," and "switch OS." Therefore,
`while input from the touch panel is permitted, any input from the keyboard 4 and the
`trackpad 5 is prohibited.
`
`[0026] If the system is not controlled so as to "prohibit input from devices other than the
`touch panel" when the rotation angle reaches 360 degrees, there may be a risk of erroneous
`inputs because the user’s finger(s) may accidentally touch the keyboard 4, etc., while
`holding the notebook computer with his or her hand in the state in which the display panel
`2 is rotated by 360 degrees as shown in Figure 4. Or, in the state in which the display panel
`2 is rotated by 360 degrees, the user may place the notebook computer on a desk or the

`

`like with the display panel 2 facing up. In this case also, the user’s finger(s) may accidentally
`touch the keyboard 4, etc., thus posing the risk of erroneous inputs. However, with the
`present embodiment, because the system is controlled so as to "prohibit input from devices
`other than the touch panel," it becomes possible to prevent such erroneous inputs.
`
`[0027] Subsequently, when the user closes the display panel 2, i.e., the rotation angle
`reaches 0 degree, the system is controlled so as to "sleep, and turn off display power."
`
`[0028] Incidentally, by way of another example, for some applications or OS that take a long
`time to start up, the rotation angle that is preset and thus registered in the system-control
`setting part 12 as the angle at which a launch instruction for such applications or OS should
`be initiated is preferably shifted — by taking account of the expected time involved in the
`launch — from the intended rotation angle at which the applications or OS should actually
`be launched. For example, the preset rotation angle may be set at 200 degrees; and the
`system control “automatically launch an application” is registered corresponding to said
`preset rotation angle in the system-control setting part 12. In this case, as the user opens
`the display panel 2, the launch of an application will be initiated when the rotation angle of
`the display panel 2 reaches 200 degrees so that the launch process may be almost complete
`by the time the rotation angle reaches 360 degrees.
`
`[0029] A locking mechanism may be provided so as to lock the display panel 2 in the closed
`state. Similarly, a locking mechanism may be provided so as to lock the display panel 2 in
`the state in which the display panel 2 is rotated by 360 degrees. The usability of the
`notebook-type personal computer shown in Figure 4 is further improved by allowing the
`display panel 2 to be locked in the 360-degree rotated state. Example structures of such
`locking mechanisms include a structure that uses an elastic claw that can latch onto a
`recessed section or a protrusion formed in/on the other side of the mating-part pair, or a
`structure that provides magnets respectively in the corresponding sections of the display
`panel 2 and the main body 1.
`
`[0030] The Figures 7 and 8 show side views of the notebook-type personal computer that
`illustrate structures for rotatably supporting the display panel 2 on the main body 1, said
`figures illustrating the state in which the display panel 2 is closed and the state in which the
`display panel 2 is rotated by 360 degrees, respectively. An intermediate hinge 6 is pivotally
`supported on a pivot 8 provided on the rear side of the main body 1; and the rear edge of
`the display panel 2 is pivotally supported on a pivot 7 that is provided on the intermediate
`hinge 6 and in parallel with a pivot 8.
`
`[0031] The present embodiment may be provided with the following elements:
`
`Lenovo EX-1014, Page 015
`IPR2021-00786 (Lenovo Inc. v. LiTL LLC.)
`
`

`

`A main-body-side sensor (not shown), which detects the angle of rotation of the
`intermediate hinge 6 relative to the main body 1;
`
`A display-panel-side sensor (not shown but may be an encoder, for example), which
`detects the angle of rotation of the display panel 2 relative to the intermediate hinge
`6; and
`
`An adder (not shown), which adds the angle detected by the main-body-side sensor
`and the angle detected by the display panel side sensor together.
`
`In this way, the output from said adder represents the rotation angle of the display panel 2;
`and therefore said adder can act as the panel sensor 14 shown in Figure 5.
`
`[0032] Furthermore, another embodiment of the present invention may be provided with
`the following elements, as shown in Figure 9:
`
`A gear 21 that is affixed to the main body 1 so as to share a common axis with the
`pivot 8;
`
`A gear 22 that is affixed to the display panel 2 so as to share a common axis with the
`pivot 7, said gear 22 having the same number of teeth as that of the gear 21;
`
`A sensor (not shown), which detects the angle of rotation of the intermediate hinge
`6 relative to the main body 1, o
