Description

Technical Field

[0001] The present invention relates to a data input device that provides an anti-theft monitoring function for a portable personal computer (PC). More specifically, the present invention relates to a data input device that, when a theft of a portable personal computer occurs, detects the situation and emits a warning sound to protect the portable personal computer from a theft suspect. Background Art

[0002] Recently, the usage rate of portable personal computers represented by laptop computers and tablet computers has been gradually increasing. However, theft cases of portable personal computers occurring in various usage spaces such as coffee shops and libraries have also increased. It is reported that about 4,000 laptop theft cases occur in Denmark every year.

[0003] Portable personal computer theft cases mainly occur when the owner of the item temporarily leaves the seat while placing the portable personal computer on a table or desk in the usage space. During the period when the owner of the item leaves the seat, when a third party approaches the portable personal computer with the purpose of theft, others other than the owner of the item do not know whether the third party has the purpose of theft. Therefore, it is very easy to steal the portable personal computer helplessly.

[0004] As a representative prior art for preventing the theft of portable personal computers, anti-theft software that is installed in a portable personal computer and used has been developed. The anti-theft software can only be used when it is running in the portable personal computer, and the software should be set to the monitoring mode state before the owner leaves the seat.

[0005] Under such usage conditions, when a third party disconnects the power supply of the portable personal computer in advance or terminates the operation of the software and then steals the portable personal computer, since the software does not work, it is actually in a state where it is impossible to prevent theft through the software. Summary of the Invention

[0027] Hereinafter, embodiments of the present invention will be described more specifically with reference to the accompanying drawings.

[0028] Figure 1 FIG. is a block diagram showing the structure of the data input device according to the first embodiment of the present invention, Figure 2 and Figure 3 FIG. is a diagram showing an application example of the data input device according to the first embodiment.

[0029] The data input device 100 is an auxiliary device for assisting the data input function of a portable personal computer.

[0030] Representative examples of portable personal computers may be laptop computers and tablet computers. However, it is not limited thereto, and the present invention is equally applicable to other types of portable personal computers that can be used while being carried.

[0031] Referring to Figure 1 , the data input device 100 includes a main body part 110 and a connection part 150.

[0032] The main body part 110 is a part that generates input data for a portable personal computer.

[0033] The connection part 150 is a part that is connected to an external communication port of a portable personal computer. The connection part 150 is wired to the main body part 110. The connection part 150 receives the data generated in the main body part 110 and transmits it to the portable personal computer.

[0034] As Figure 2 shown, the data input device 100 can be implemented as a wired mouse. In this case, the main body part 110 is embodied as a mouse main body, and the connection part 150 is embodied as a Universal Serial Bus terminal (USB terminal) connected to the main body part 110 through a cable.

[0035] As Figure 3 shown, the data input device 100 can be embodied as a wired keyboard. In this case, the main body part 110 is embodied as a keyboard main body, and the connection part 150 is embodied as a Universal Serial Bus terminal connected to the main body part 110 through a cable.

[0036] The data input device 100 according to the first embodiment is not limited to a wired mouse and a wired keyboard, and can also be implemented as other types of devices composed of a main body part that generates input data and a connection part that is wired to it.

[0037] Refer again to Figure 1 , the connection part 150 includes a coordinate detection sensor 151 and a Universal Serial Bus extender (USB Hub) controller 152.

[0038] The coordinate detection sensor 151 is a sensor for detecting the movement of the portable personal computer. As an example, the coordinate detection sensor 151 can be set as a gyro sensor.

[0039] The Universal Serial Bus extender controller 152 is wired-connected to the main body part 110 and the coordinate detection sensor 151 respectively.

[0040] The Universal Serial Bus extender controller 152 has 2 receiving channels and 1 transmitting channel. The channel marked as "USB1DP / USB 1DN" is the first receiving channel, the channel marked as "USB 2DP / USB 2DN" is the second receiving channel, and the channel marked as "DP / DN" is the transmitting channel.

[0041] The Universal Serial Bus extender controller 152 receives the data of the coordinate detection sensor 151 through the first receiving channel and receives the data of the main body part 110 through the second receiving channel. Moreover, the Universal Serial Bus extender controller 152 sends data to the portable personal computer through the transmitting channel.

[0042] When vibration or impact is applied to the portable personal computer or the portable personal computer is moved by someone, that is, a change in the position of the portable personal computer occurs, and this position change is detected by the coordinate detection sensor 151 installed inside the connection part 150.

[0043] The signal detected by the coordinate detection sensor 151 is transmitted to the Universal Serial Bus extender controller 152 through the first receiving channel, and the Universal Serial Bus extender controller 152 analyzes the signal transmitted from the coordinate detection sensor 151 to determine whether the position of the portable personal computer has changed.

[0044] If it is determined that the position of the portable personal computer has changed, the Universal Serial Bus extender controller 152 transmits a signal for emitting an alarm sound to the portable personal computer, and the portable personal computer immediately emits a loud alarm sound after receiving this signal.

[0045] Thus, when the owner temporarily leaves the seat during the use of the portable personal computer and a third party touches or moves the portable personal computer for theft, a loud alarm sound immediately emits from the portable personal computer, thereby preventing the portable personal computer from being stolen in this way.

[0046] If the connection part 150 is separated from the portable personal computer by a theft suspect, the function of emitting an alarm sound is stopped. However, the connection part 150 of the present invention is different from a wired mouse, a wired keyboard, etc., and is embodied as a universal serial bus terminal, and its appearance is no different from that of a normal universal serial bus terminal. Thus, the connection part 150 of the present invention looks like a normal universal serial bus terminal from the outside, and thus, it is difficult for a theft suspect to think of separating the connection part 150 from the portable personal computer to prevent the alarm sound from being emitted. In this way, although the coordinate detection sensor 151 for anti-theft is installed inside the connection part 150 of the present invention, it is difficult to attract the attention of the theft suspect to its existence. In this sense, the coordinate detection sensor 151 that is invisibly installed inside the connection part 150 having the appearance of a normal universal serial bus terminal can be regarded as a structure that acts like a spy.

[0047] As described above, the universal serial bus extender controller 152 is provided with two receiving channels, receives the data of the coordinate detection sensor 151 through the first receiving channel, and receives the data of the main body part 110 through the second receiving channel.

[0048] In this way, the data of the coordinate detection sensor 151 and the data of the main body part 110 are respectively transmitted to the universal serial bus extender controller 152 through separate channels, and "data jam" in which the two data do not conflict with each other does not occur during the transmission of the two data.

[0049] If the data of the coordinate detection sensor 151 and the data of the main body part 110 are transmitted to the universal serial bus extender controller 152 through a common channel, the two data cannot be transmitted to the universal serial bus extender controller 152 at the same time. Therefore, the data transmission of one of them will be blocked. Therefore, it is possible that the data of the coordinate detection sensor 151 cannot be transmitted to the universal serial bus extender controller 152 due to interference with the data of the main body part 110. In this case, the coordinate detection sensor 151 for anti-theft monitoring may not function properly.

[0050] On the contrary, in the case of the present invention, a receiving channel for the coordinate detection sensor 151 is separately allocated in the universal serial bus extender controller 152, so a situation where the function of the coordinate detection sensor 151 is hindered due to data conflict does not occur.

[0051] Figure 4 A block diagram showing the structure of the data input device according to the second embodiment of the present invention.

[0052] Similar to the data input device 100 of the first embodiment, the data input device 200 of the second embodiment also includes a main body part 210 and a connection part 250, and can be implemented as an input device such as a wired mouse or a wired keyboard.

[0053] In the case where the data input device 200 is a wired mouse, the main body portion 210 is embodied as a mouse body, and the connection portion 250 is embodied as a universal serial bus terminal connected to the mouse body through a cable. In the case where the data input device 200 is a wired keyboard, the main body portion 210 is embodied as a keyboard body, and the connection portion 250 is embodied as a universal serial bus terminal connected to the keyboard body through a cable.

[0054] In the case of the second embodiment, the main body portion 210 includes a main circuit 211 and a universal serial bus extender controller 212, and the connection portion 250 includes a coordinate detection sensor 251. Among them, the main circuit 211 is a circuit that performs the basic functions of the main body portion 210, that is, a circuit related to generating input data.

[0055] Compared with the first embodiment, the difference in the second embodiment is that the universal serial bus extender controller 212 is provided in the main body portion 210.

[0056] However, from a functional level, the universal serial bus extender controller 212 in the second embodiment is almost the same as the universal serial bus extender controller 152 in the first embodiment. The explanation for this is as follows.

[0057] The universal serial bus extender controller 212 has a first receiving channel labeled "USB 1DP / USB 1DN", a second receiving channel labeled "USB 2DP / USB 2DN", and a transmitting channel labeled "DP / DN". The universal serial bus extender controller 212 receives data from the coordinate detection sensor 251 through the first receiving channel, receives data from the main circuit 211 through the second receiving channel, and transmits data to the portable personal computer through the transmitting channel.

[0058] The universal serial bus extender controller 212 analyzes the signal transmitted from the coordinate detection sensor 251. If it is determined according to the analysis that the position of the portable personal computer has changed, it transmits a signal for emitting an alarm sound to the portable personal computer, and the portable personal computer immediately emits an alarm sound for anti-theft after receiving this signal.

[0059] In the data input device 200 of the second embodiment, a receiving channel for the coordinate detection sensor 251 is also separately allocated in the universal serial bus extender controller 212. Therefore, the situation where the coordinate detection sensor 251 cannot function properly due to data conflict will not occur.

[0060] On the other hand, in the first embodiment, both the coordinate detection sensor 151 and the universal serial bus extender controller 152 are provided in the connection part 150. In contrast, in the second embodiment, only the coordinate detection sensor 251 is provided in the connection part 250. Accordingly, the size of the connection part 250 in the second embodiment can be designed to be smaller.

[0061] Figure 5 FIG. is a block diagram showing the structure of a data input device according to a third embodiment of the present invention, Figure 6 and Figure 7 FIG. is a diagram showing an application example of the data input device according to the third embodiment.

[0062] The data input device 300 is an auxiliary device for assisting the data input function of a portable personal computer.

[0063] Representative examples of the portable personal computer may be a laptop computer, a tablet computer. However, it is not limited thereto, and the present invention is equally applicable to other types of portable personal computers that can be used while being carried.

[0064] Referring to Figure 5 , the data input device 300 includes a main body part 310 and a connection part 350.

[0065] The main body part 310 is a part that generates input data for the portable personal computer.

[0066] The connection part 350 is a part that is connected to an external communication port of the portable personal computer. The connection part 350 is wirelessly connected to the main body part 310. The connection part 350 receives the data generated in the main body part 310 and transmits it to the portable personal computer.

[0067] As Figure 6 shown, the data input device 300 is implemented as a wireless mouse corresponding to the main body part 310 and a universal serial bus receiver (USB dongle) corresponding to the connection part 350. Alternatively, as Figure 7 shown, the data input device 300 may be implemented as a wireless keyboard corresponding to the main body part 310 and a universal serial bus receiver corresponding to the connection part 350.

[0068] Referring again to Figure 5 , the connection part 350 includes a wireless reception part 351, a coordinate detection sensor 352, and a universal serial bus extender controller 353.

[0069] The wireless reception part 351 receives the input data generated in the main body part 310 through wireless communication and transmits it to the universal serial bus extender controller 353.

[0070] The coordinate detection sensor 352 is a sensor for detecting the movement of the portable personal computer. As an example, the coordinate detection sensor 352 can be set as a gyro sensor.

[0071] The universal serial bus extender controller 353 is wired to the wireless receiving unit 351 and the coordinate detection sensor 352 respectively.

[0072] The universal serial bus extender controller 353 has two receiving channels and one transmitting channel. The channel marked as "USB1DP / USB 1DN" is the first receiving channel, the channel marked as "USB 2DP / USB 2DN" is the second receiving channel, and the channel marked as "DP / DN" is the transmitting channel.

[0073] The universal serial bus extender controller 353 receives the data of the coordinate detection sensor 352 through the first receiving channel, and receives the data of the main body part 310 through the second receiving channel. Moreover, the universal serial bus extender controller 353 transmits data to the portable personal computer through the transmitting channel.

[0074] The functions of the coordinate detection sensor 352 and the universal serial bus extender controller 353 are the same as those described in the foregoing embodiments. That is, if the movement (position change) of the portable personal computer is detected by the coordinate detection sensor 352, the universal serial bus extender controller 353 transmits a signal for emitting an alarm sound to the portable personal computer, and the portable personal computer immediately emits an alarm sound for anti-theft after receiving this signal.

[0075] The connection part 350 of the present invention has an appearance identical to that of an ordinary universal serial bus receiver. Thus, the connection part 350 of the present invention looks like an ordinary universal serial bus terminal from the outside, so it is difficult for a theft suspect to think of separating the connection part 350 from the portable personal computer to prevent the alarm sound from being emitted. In this way, although the coordinate detection sensor 352 for anti-theft is installed inside the connection part 350 of the present invention, it is difficult to attract the attention of the theft suspect to its existence. In this sense, the coordinate detection sensor 352 installed invisibly inside the connection part 350 with the appearance of an ordinary universal serial bus terminal can be regarded as a structure that acts like a spy.

[0076] As described above, the universal serial bus extender controller 353 is provided with two receiving channels, receives the data of the coordinate detection sensor 352 through the first receiving channel, and receives the data of the main body part 310 through the second receiving channel. In this way, a receiving channel dedicated to the coordinate detection sensor 352 is separately allocated in the universal serial bus extender controller 353, so that the situation where the function of the coordinate detection sensor 352 is hindered due to data conflict does not occur.

[0077] Figure 8 A block diagram showing the structure of the data input device according to the fourth embodiment of the present invention.

[0078] Similar to the data input device 300 of the third embodiment, the data input device 400 of the fourth embodiment includes a main body portion 410 and a connection portion 450. Also, similar to the data input device 300 of the third embodiment, the data input device 400 of the fourth embodiment can also be implemented as a wireless mouse corresponding to the main body portion 410 and a universal serial bus receiver corresponding to the connection portion 450, or as a wireless keyboard corresponding to the main body portion 410 and a universal serial bus receiver corresponding to the connection portion 450.

[0079] In the case of the fourth embodiment, the connection portion 450 includes a wireless receiving unit 451 and a coordinate detection sensor 452.

[0080] The wireless receiving unit 451 receives the input data generated in the main body portion 410 through wireless communication. Further, the wireless receiving unit 451 also functions as the aforementioned universal serial bus extender controller. That is, the wireless receiving unit 451 receives and analyzes the data of the coordinate detection sensor 452, and if it determines that the portable personal computer has moved, it transmits a signal for emitting an alarm sound for anti-theft to the portable personal computer.

[0081] In the case of the fourth embodiment, the connection portion 450 has a structure in which the wireless receiving unit 451 also functions as a universal serial bus extender controller, and can be manufactured in a smaller size compared to the connection portion 350 of the third embodiment.

[0082] The wireless receiving unit 451 is separately assigned a channel for receiving the data of the coordinate detection sensor 452. Therefore, similar to the previous embodiments, the situation where the coordinate detection sensor 452 cannot function properly due to data conflict does not occur.
