[0024] 其中上述的超声波感应单元101可设于本体1的底部表面,使得本体1放置于一承载物40 (如:桌子)时,超声波感应单元101可面对此承载物40,而对承载物40发出超声波信号。 [0024] wherein said ultrasonic sensing unit 101 may be disposed on a bottom surface of the body 1, so that the body 1 is placed on a carrier 40: (such as a table), ultrasonic sensing unit 101 may face this carrier 40, while the carrier ultrasonic signal 40 was sent. 然而,超声波感应单元101所限定的位置并不仅限于本体1的底部表面,本发明的另一实施例中,请参阅图3所示,超声波感应单元101也可能倾斜地设于本体1周围的侧面,使得超声波感应单元101可藉由一适当角度而仍可面对承载物40,或者本体1外围环境的一参考物(如:桌面或桌面上的水杯),如此一来,本体1离开此承载物40时,势必也会与参考物之间增加或减少相对距离。 However, ultrasonic sensing unit 101 is not limited to positions defined by the bottom surface of the body 1, another embodiment of the present invention, please refer to FIG. 3, the ultrasonic sensing unit 101 may also be provided on the inclined side surface around the body 1 , so that ultrasonic sensing unit 101 may by a suitable angle while still bearing face 40, a body or a peripheral environment of the reference object (such as: a desktop or on glass), this way, to leave the carrier body 1 when 40, will inevitably increase or decrease the relative distance between the object and the reference.

[0025] 而此警报模块20包括一警报单元201 (alarm)及警报单元驱动电路202,警报单元201设于本体1可对外发出警报的位置,如设于本体1底部表面的一蜂鸣器,用以由本体1 的底部表面对外发出尖锐的警报声,而警报单元驱动电路202电气连接警报单元201及中央控制单元30,当中央控制单元30受到此比较电路104的通知时,中央控制单元30便可命令警报单元驱动电路202,以驱动此警报单元201。 [0025] and this alarm module 20 includes an alarm unit 201 (Alarm) driving circuit 202 and the alarm unit, the alarm unit 201 may be provided at a position of the body's external alarm, such as a buzzer provided in the bottom surface of the body 1, to the external surface of a sharp warning sound from the bottom of the body 1, and the alarm unit driving circuit 202 is electrically connected alarm unit 201 and a central control unit 30, when the central control unit 30 notifies by this comparison circuit 104, the central control unit 30 The alarm unit can command the drive circuit 202 for driving the alarm unit 201.

[0026] 如此一来,当本体1被放置于承载物40上,且开机后进入一操作系统时,请参阅图1、图4所示,图4是便携式计算机装置防盗方法的流程图。 [0026] Thus, when the body 1 is placed on the carrier material 40, and the boot into an operating system, please refer to FIG. 1, FIG. 4, FIG. 4 is a flowchart of a method of the anti-theft device of the portable computer. 本体1内的中央控制单元30便依下列方式进行处理: The central control unit 30 in the body 1 will be processed in accordance with the following manner:

[0027] 步骤401,正常使用操作系统; [0027] Step 401, the normal use of the operating system;

[0028] 步骤402,判断是否退出操作系统: [0028] Step 402, it is determined whether to exit the operating system:

[0029] 本体1常于二种情况下退出操作系统,一则为本体1被使用者主动操作而退出操作系统,二则为本体1于闲置一段时间,自动进入保护模式而退出操作系统,若本体1退出操作系统时,则中央控制单元30便进行步骤403,否则,中央控制单元30便回到步骤401 ; [0029] The body 1 normally exit in either case the operating system, a main body 1 are compared with a user exit the operating system is actively operating, two compared to a period of inactivity of the body 1, exit automatically protected mode operating system, if when the main body 1 exits the operating system, the central control unit 30 then proceeds to step 403, otherwise, the central control unit 30 then returns to step 401;

[0030] 步骤403,启动超声波感应模块10及警报模块20 ; [0030] Step 403 to start ultrasonic sensing module 10 and the alarm module 20;

[0031] 中央控制单元30便启动上述的超声波感应模块10及警报模块20及其内的各组件,如此,超声波感应模块10内的感应单元驱动电路102接着连续产生多个超声波信号,而依序由超声波感应单元101发出,各超声波信号发出后会分别到达本体1所放置的承载物40上,再分别被承载物40弹回,弹回后的各超声波信号则依序被超声波感应单元101所接收,而信号接收电路103接收由超声波感应单元101所传递的超声波信号后,经处理而取得超声波信号的折返时间; [0031] The central control unit 30 then starts the components within the sensing module 10 and the ultrasonic alarm module 20 and, thus, ultrasonic sensing module sensing unit 10 in the driving circuit 102 then generates a plurality of consecutive ultrasonic signal, and sequentially issued by the ultrasonic sensing unit 101, the body will reach a carrier was placed after each respective ultrasonic signal is issued 40, the carrier 40 are then spring back, each of the ultrasonic signal after the spring back was sequentially ultrasonic sensing unit 101 after reception, the signal receiving circuit 103 receives the ultrasonic signal by the ultrasonic sensing unit 101 is delivered, treated folded acquired time of the ultrasonic signal;

[0032] 步骤404,取得本体1与承载物40间的距离: [0032] Step 404, the main body 40 made from bearing material and 1:

[0033] 信号接收电路103再将超声波信号的折返时间传至比较电路104,比较电路104依据各超声波信号所花费的折返时间依序计算出各超声波信号最远所到达的距离,即为本体1与承载物40间的距离; And then folded back time of the ultrasonic signal 103 [0033] The signal receiving circuit 104 is transmitted to the comparison circuit, the comparison circuit 104 based on time of each ultrasonic signal folded takes sequentially calculates the distance between each ultrasonic signal reached by far, is the main body 1 and the carrier 40 from the object;

[0034] 步骤405,判断本体1与所放置承载物40的距离是否改变: [0034] Step 405, it is determined whether to change the main body 1 and the carrier 40 is placed a distance of:

[0035] 比较电路104还会依序比较最新超声波信号所到达的距离与上一笔超声波信号所到达的距离是否一致,当比较电路104发现最新超声波信号所到达的距离与上一次超声波信号所到达的距离不一致时,则比较电路104便会发出一通知信号(如:高或低电位电压)至中央控制单元30,中央控制单元30便进行步骤406,反之,中央控制单元30则回到步骤402 ;[0036] 步骤406,启动警报单元201对外发出警报声: [0035] The comparator circuit 104 will compare sequentially from the latest ultrasonic signal coincides with the arrival of the ultrasonic signal from the sum reached, the comparison circuit 104 when the ultrasonic signal is found from the latest arrival time of the ultrasonic signal reaches the when the distance is inconsistent, the comparator circuit 104 will issue a notification signal (such as: high voltage or low voltage) to the central control unit 30, the central control unit 30 then proceeds to step 406, whereas the central control unit 30 returns to step 402 ; [0036] step 406, the alarm unit 201 starts the external sound an alarm:

[0037] 中央控制单元30接到比较电路104所发出的通知信号后,便会通知警报单元驱动电路202,使得警报单元驱动电路202驱动警报单元201对外发出警报声; After [0037] The central control unit 30 receiving the notification signal sent by the comparison circuit 104, the alarm unit will inform the driver circuit 202, an alarm unit such that the driving circuit 202 drives the external alarm 201 to sound an alarm unit;

[0038] 步骤407,判断是否登陆操作系统: [0038] In step 407, it is determined whether the landing operating system:

[0039] 此时,中央控制单元30持续判断本体1目前的状态是否仍处于退出操作系统下, 若登陆操作系统的指示(如:登陆密码、手指指纹或组合按键)正确时,中央控制单元30便进行步骤408,否则,中央控制单元30仍回到步骤406,持续对外发出警报声; [0039] At this time, the central control unit 30 continuously determines whether a current state of the body is still in the exit operating system, the operating system when the landing indication (eg: login password, fingerprints, or combination of keys) is correct, the central control unit 30 then proceeds to step 408, otherwise, the central control unit 30 still returns to step 406 for the external sound an alarm;

[0040] 步骤408,关闭超声波感应模块10及警报模块20,返回步骤401。 [0040] Step 408, the sensing module 10 and the ultrasound off the alarm module 20 returns to step 401.

[0041] 由于登陆操作系统的指示(如:登陆密码、手指指纹或组合按键)正确,则中央控制单元30判断出本体1目前的状态已处于登陆操作系统的状态时,则上述的超声波感应模块10及警报模块20及其内的各组件便因此被中央控制单元30所关闭,如此,感应单元驱动电路102便不再发出超声波信号,而警报单元驱动电路202便不再驱动警报单元201,而因此停止对外发出警报声。 [0041] Since the landing operating system indication (eg: login password, fingerprints, or combination of keys) is correct, the central control unit 30 determines the state of a current state of the body is in the landing operating systems, the above ultrasonic sensing module 10 and alarm module 20 and the components within it is thus closed by the central control unit 30, thus, the sensing unit drive circuit 102 will no longer emit an ultrasonic signal, the alarm unit and the driving circuit 202 is no longer driving the alarm unit 201, and So stop External alarm will sound.

[0042] 综上所述,本发明便携式计算机装置利用超声波感应模块10计算本体1与其承载物40相隔的距离,一旦距离改变,则便携式计算机装置则有可能被窃贼带走,则便携式计算机装置再因此发出警报,以警告使用者,以便保护便携式计算机装置。 [0042] In summary, the present invention is a portable computer apparatus using ultrasonic sensing module 10 calculates the body 1 and its bearing 40 is spaced a distance, once the distance change, the portable computer device is likely to be thieves away, then the portable computer device Thus an alarm to warn the user, in order to protect the portable computer device.

[0043] 当然,本发明还可有其他多种实施例,在不背离本发明精神及其实质的情况下,熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形,但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。 [0043] Of course, the present invention may have various other embodiments without departing from the spirit and the essence of the present invention, those skilled in the art can make various corresponding modifications and variations according to the present invention, but these corresponding changes and variations should fall within the scope of the appended claims.
