DETAILED DESCRIPTION OF THE INVENTION
The making and using of the embodiments of the present invention are discussed in detail below. It should be appreciated, however, that the embodiments provide many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.
FIG. 1A is a schematic diagram illustrating an embodiment of a computer integral device 100 when an external electronic device 130 is not placed thereon, while FIG. 1B shows a diagram has been placed onto the external electronic device 130. The computer integral device 100 of the present embodiment turns on/off a computer host by detecting the existence of the external electronic device 130 via a detection unit 110. This is different from the conventional computer device being turned on/off by a power button. When the detection unit 110 detects that the external electronic device 130 is in the determined position, the detection unit 110 makes two power control pins of the computer host 120 short-circuited. When the detection unit 110 does not detect that the external electronic device 130 is in the determined position, the detection unit 110 makes two power control pins of the computer host 120 open-circuited. Accordingly, an impulse signal is generated due to these two statuses of the two power control pins. FIG. 1C illustrates the impulse signal at time Tt, which controls the computer turn on/off process of the computer host 120. At the time just after the computer turn on process is executed, the wireless communication link between the external electronic device 130 and the computer host 120 has not been established, and the computer host 120 does not recognize which external electronic device triggered this computer turn on process. Thus, the computer host 120 broadcasts a turn on notice signal to the external electronic device 130 via wireless communication so as to inform the external electronic device 130 of the computer host 120 is available for establishment of a wireless communication link. As a result, when the computer host 120 broadcasts a turn on notice signal, the external electronic device 130 may receive this turn on notice signal from the computer host 120 by the wireless communication. The external electronic device 130 may obtain associated information of the computer host 120 by means of the turn on notice signal, and further display a message that the computer host 120 is available for establishment of a wireless communication link on the screen (not shown) of the external electronic device 130. Thus, a user may select the computer host 120 from the external electronic device 130, and then notify the computer host 120 for establishment of a wireless communication link therewith. In the illustrated embodiment, after the wireless communication link between the external electronic device 130 and the computer host 120 is established, the external electronic device 130 may operate as a monitor of the computer host 120. The user may input instructions via a keyboard or mouse of the computer host 120, and associated responses of the instructions may be displayed on the screen of the external electronic device 130 by the wireless communication link. Therefore, a user may use the computer host 120 to operate complex operations, when the external electronic device 130 works as a monitor of the computer host 120. It should be noted, that the user may also input instructions via the external electronic device 130, and those who are skilled in this technology may add this function without departing from the scope and spirit of this invention.
Although the impulse signal is performed by a high voltage level being switched to a low voltage level for example, it may also be performed by a low voltage level being switched to a high voltage level.
FIG. 1D is a block diagram illustrating an embodiment of a computer integral device 100. The computer integral device 100 comprises a detection unit 110 and a computer host 120. The computer host 120 is coupled to the detection unit 110. In order to connect the computer host 120 and the external electronic device 130 together more conveniently, the detection unit 110 determines whether to turn on the computer host 120 by detecting whether the external electronic device 130 is in a determined position. For example, if the detection unit 110 is an infrared ray detection unit, it may set an infrared ray sensor in the determined position (such as in a foundation or any base capable of holding the external electronic device). Thus, when the external electronic device 130 is moved in or out of the determined position, the infrared ray sensor may transmit a signal to the computer host to notify the computer host and further activate the computer turn on/off process accordingly. In another illustrated embodiment, the detection unit 110 may be also performed by a pressure detection unit to detect whether the external electronic device 130 is moved into the determined position and whether the external electronic device 130 is moved out of the determined position, and further transmit a signal to the computer host to notify the computer host and further activate the computer turn on/off process accordingly. For example, the detection unit 110 may generate a power enable signal Senable or a power disable signal Sdisable to control the turn on/off of the computer host 120 according to the detection of whether the external electronic device 130 has placed in the determined position.
In the illustrated embodiment, when a user puts the external electronic device 130 in the determined position, the detection of the detection unit 110 may detect that the external electronic device 130 is in the determined position. Thus, the detection unit 110 may know that the external electronic device 130 has been moved to the determined position, and further transmit the power enable signal Senable to the computer host 120. The computer host 120 executes the turn on process according to the power enable signal Senable. When a user moves the external electronic device 130 out of the determined position, the detection of the detection unit 110 may detect that the external electronic device 130 is not in the determined position. Thus, the detection unit 110 may know whether the external electronic device 130 has been moved out of the determined position, and further transmit the power disable signal Sdisable to the computer host 120. The computer host 120 executes the turn off process according to the power disable signal Sdisable. In another illustrated embodiment, the computer host 120 may execute a standby process according to the power disable signal Sdisable depending user requirements.
FIG. 2 is a block diagram illustrating an embodiment of a computer integral system 200. The computer integral system 200 comprises a computer integral device 210 and an external electronic device 240, wherein the computer integral device 210 comprises a detection unit 220 and a computer host 230 with a computer communication unit 232 and image data 234. And the external electronic device 240 comprises an external communication unit 242, a display unit 244, and an external input unit 246.
In the illustrated embodiment, when a user places the external electronic device 240 (such as tablet personal computer) in the determined position, the detection unit 220 may know whether the external electronic device 240 has been moved to the determined position and then assert the power enable signal Senable to the computer host 230. After that, the computer host 230 executes the turn on process according to the power enable signal Senable. When a user removes the external electronic device 240 from the determined position, the detection unit 220 may know whether the external electronic device 240 has been moved out of the determined position, and further assert the power disable signal Sdisable to the computer host 230. After that, the computer host 230 executes the turn off process according to the power disable signal Sdisable. In another illustrated embodiment, the computer host 230 may execute a standby process according to the power disable signal Sdisable depending on system manufacturer' requirements. In the illustrated embodiment, the external electronic device 240 is a tablet personal computer, wherein the tablet personal computer may be any type of tablet personal computer, and the tablet personal computer is not limited to a brand, shape, specification or size. It should be noted, that the tablet personal computer is already turned on in this embodiment. Thus, it may operate as a display monitor after associated wireless communication link with the computer host 230 is established, which will be explained more detailed in the following descriptions.
In some illustrated embodiments, the applications between the computer integral device 210 and the external electronic device 240 can be further integrated. For example, due to the computer host 230 is unaware of which external electronic device triggers the computer turn on process after executing the turn on process, the computer host 230 may broadcast a turn on notice signal Sn to inform the external electronic device 240 via wireless communication. In an illustrated embodiment, the turn on notice signal Sn transmitted from the computer host 230 is received by the external communication unit 242, and is analyzed therein so as to obtain associated information of the computer host 230 by a processor (not shown) of the external electronic device 240. Finally, the display unit 244 displays a message illustrative of the fact that the computer host 230 is available for establishment of a wireless communication link. Thus, after a user selects the computer host 230 for connecting with the external electronic device 240, associated selecting instructions, including associated information of the external electronic device 240, may be transmitted as a control signal Sc to the computer host 230 by the external input unit 246 of the external electronic device 240, and the computer host 230 is notified for establishment of a wireless communication link WL for operations accordingly (such as accessing the computer host 230). After the wireless communication link WL between the external electronic device 240 and the computer host 230 is established, the external electronic device 240 may work as a display monitor of the computer host 230. Thus, a user may input instructions on the computer host 230, and the responses of the instructions is transformed into an image signal Si, and then the image signal Si is transmitted to the external communication unit 242 of the external electronic device 240 by the computer communication unit 232. After the image signal Si is processed by the processor of the external electronic device 240, the responses of the instructions can be displayed on the display unit 244 of the external electronic device 240. Accordingly, a user may use the display unit 244 of the external electronic device 240 to display the image data 234 of the computer host 230 without any additional display device coupled with the computer host 230.
It should be noted, a user may input instructions by the external electronic device 240, which may be transformed into an instruction control signal Sc′, and then the instruction control signal Sc′ is transmitted to the computer communication unit 232 of the computer host 230 by the external input unit 246. The response of the instruction as the image data 234 is transformed into the image signal Si, and transmitted to the external communication unit 242. After the image signal Si is manipulated by the processor of the external electronic device 240, the responses of the instructions can be displayed on the display unit 244 of the external electronic device 240. Those who are skilled in this technology may add this function without departing from the scope and spirit of this invention.
Further, although there is only one computer host 230 in this embodiment of the computer integral system, the external electronic device 240 may also receive turn on notification signals from another computer hosts by means of wireless communications. Thus, a user may decide which one of the computer hosts to link therewith, and he/she may select a proper computer host as his/her requirements. After the wireless communication link WL between the external electronic device 240 and the computer host 230 is established, the computer communication unit 232 transmits the image signal Si to the external communication unit 242 according to the image data 234, and then the display unit 244 of the external electronic device 240 displays the corresponding image of the image data 234 according to the image signal Si. Thus, a user may use the display unit 244 of the external electronic device 240 to display current image outputs of the computer host 230. Accordingly, it is unnecessary for the computer host 230 to connect to a display device, as the external electronic device 240 (such as a tablet PC) may display the current image outputs.
In some illustrated embodiments, the external electronic device 240 may control other operations of the computer integral device 210. For example, after the computer host 230 executes the turn on process, a user may select the computer host 230 to perform an operation via wireless communication. In the meantime, the wireless communication link WL between the external communication unit 242 and the computer host 230 has not yet been established, but the external communication unit 242 may transmit a control signal Sc to the computer host 230 according to the selection of a user via wireless communication, and then the computer host 230 is notified by the control signal Sc for establishment of a wireless communication link WL according to the instruction inputted by a user. After the wireless communication link WL is established, the display unit 244 works as a display monitor of the computer host 230. Thus, associated image data of the responses of the instructions from the user is displayed by means of the display unit 244 of the external electronic device 240 via the wireless communication link WL. For example, a user may input a disconnect instruction via the external input unit 246, such that the computer host 230 stops transmitting a signal to the external electronic device 240 according to this disconnect instruction. Thus, the wireless communication link between the computer host 230 and the external electronic device 240 would be disconnected. The disconnect instruction illustrated herein is used for the sake of explanations, but the control instruction of the embodiment is not limited thereto. In some of illustrated embodiments, a user may input the instruction via the external input unit 246, or a keyboard or mouse coupled to the computer host 230 or the external electronic device 240. In some of illustrated embodiments, the image signal Si and the instruction control signal Sc′ may be transmitted and received via wireless network or blue-tooth communication. After the wireless communication link WL between the external communication unit 242 and the computer host 230 is established, it may transmit the image signal Si or the instruction control signal Sc′ in a real-time manner. However, the capacity of the transmitted data is pretty large. Obviously, it consumes a lot of system resources of the external electronic device 240 and the computer host 230, and thus increases the loads of CPU and memory. In order to improve whole system performances, the computer host 230 may use a multiple-core processor to execute associated operation, such as a Quad-Core processor, and the external electronic device 240 may use a processor with a core faster than 1 GHz.
FIG. 3 is a flowchart of an embodiment of a method for the computer integral system 200 shown in FIG. 2.
In the step S302, whether the external electronic device 240 is in a determined position is detected. When the detection of the detection unit 220 detects that the external electronic device 240 has been placed in the determined position, the detection unit 220 recognizes that the external electronic device 130 has been moved to the determined position and then activate step S304A. Conversely, when the detection of the detection unit 220 detects that the external electronic device 240 has been moved out of the determined position, the detection unit 220 recognizes this situation so as to activate step S304B.
In step S304A, the detection unit 220 transmits the power enable signal Senable to the computer host 230. In step S306A, the computer host 230 executes the turn on process according to the power enable signal Senable. Due to the computer host 230 is unaware of which external electronic device triggers the computer turn on process, the computer host 120 may broadcast a turn on notice signal Sn. In step 5308A, after the computer host 120 transmits a turn on notice signal Sn to the external communication unit 242 of the external electronic device 240 via a wireless communication link. When the external electronic device 240 receives the turn on notice signal, a message that the computer host 120 is available for establishment of a wireless communication link may display on the display unit 244 waiting for user's selection. In step 310A, a user may select the computer host 230 by means of the external input unit 246 of the external electronic device 240, and then notify the computer host 120 of activating associated operations of establishment of a wireless communication link with the computer host 230. After establishing the wireless communication link WL with the computer host 230, in the step S312A, the computer host 230 transmits the image signal Si to the external electronic device 240. In step S314A, the display unit 244 of the external electronic device 240 displays corresponding image of the image data 234 according to the image signal Si.
The detection unit 220 transmits the power disable signal Sdisable to the computer host 230 in step S304B. And then in the step S306B, the computer host 230 executes the computer turn on process or the computer standby process according to the power disable signal Sdisable.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. Those who are skilled in this technology can still make various alterations and modifications without departing from the scope and spirit of this invention. Therefore, the scope of the present invention shall be defined and protected by the following claims and their equivalents.
