Embodiment
Please refer to Fig. 2, Fig. 3 A, Fig. 2 is information processing system configure figure of the present utility model; Fig. 3 A is the of the present utility model first wireless Trackpad arrangement plan.Information handling system includes a portable information processing device 100 and a wireless Trackpad 200.Comprise a storage tank 120, keyboard 150, a display interface 160 and a wireless receiver module 140 in the portable information processing device 100; And include an induction planes 201, a sensor circuit 204, one embedded antenna 220 and a wireless module 210 in the wireless Trackpad 200.
Portable information processing device 100 can be notebook, flat computer or PDA(Personal Digital Assistant), in portable information processing device 100, have a storage tank 120 and be positioned at the side of portable information processing device 100, when wireless at ordinary times Trackpad 200 does not use, wireless Trackpad 200 is placed in storage tank 120, when user's desire is used, wireless Trackpad 200 inwardly can be pressed, then wireless Trackpad 200 will slowly eject storage tank 120, be positioned over suitable position according to user ' s preference, just can use wireless Trackpad 200.Certainly, the utility model is not limited to this unimodality, and also available pulling out or mode that Electronic Control ejects breaks away from storage tanks 120 with wireless Trackpad 200, all do not break away from the novel spirit of this use.In addition, in Fig. 2, the portable information processing device 100 that can also find to use wireless Trackpad 200 and cooperate storage tank 120,200 lower positions that need not be set at keyboard 150 of Trackpad, so keyboard 150 is body lower limb 110 configurations of portable information processing device 100 in the past, compared with the device of the fixed Trackpad of general tool, allow the user under the situation that more meets ergonomics, operation keyboard 150.On the other hand, wireless Trackpad 200 does not need the height ornaments with portable information processing device 100, so it is more frivolous flat that wireless Trackpad 200 becomes, user's hand and portable information processing device 100 will not have the drop on the height, in the use can more apparent comfortable convenience.
Portable information processing device 100 has a wireless receiver module 140, and this wireless receiver module 140 is to be used for receiving the signal of being passed back by wireless Trackpad 200, and this wireless receiver module 140 is integrated in the System on Chip/SoC.Wireless receiver module 140 can have multiple on-line mode, and general short range wireless transmission method commonly used is frequency microwave (RF), for example is applicable to this kind of transceiver of ADF7012 of low data rate radio communication.The operating frequency of ADF7012 is 50MHz to 1GHz, just in time is applicable to frequency microwave (RF) wireless remote control and wireless senser.ADF7012 is a single-chip, low-power consumption VHF/UHF transmitter, and the ISM band transceiver data transfer rate of transporting this low data rate radio communication can reach 150Kbps.The radio transmitting method of also available blue bud wireless (bluetooth), on device, can adopt the blue bud chip of the blue bud specification of tool, can support adaptive frequency hopping (AFH) as the blue bud chip of BRF6150, and expanded method at synchronous connection, overcome closely in 802.11b and the intrinsic common appearance problem of bluetooth system, make the both be operated in the 2.45GHz frequency range, the blue bud chip of utilization BRF6150 is not wireless Trackpad 200, more can integrate the peripheral product of other blue bud.Certainly, this novel wireless transmission that also can use 802.11b in the WiFi wireless transmission protocol or 802.11g communication protocol to do longer distance.
Refer again to Fig. 3 A and Fig. 3 B, wherein 3B is the of the present utility model second wireless Trackpad arrangement plan, in wireless Trackpad 200, there is an induction planes 201, induction planes 201 provides the user can be with producing an induced signal after the finger touches, wireless Trackpad 200 of the present utility model is a capacitance type touch-control panel, the transparency electrode (not illustrating) that utilization is arranged combines the capacitance variations that is produced with the static between the human body, detects its coordinate from the induced current that is produced.Principle of induction acts on four corners of induction planes 201 and forms a stationary electric field with voltage, when induction planes 201 is bumped at the finger place, can make electric field cause electric current, measure by a sensor circuit 204 under induction planes 201, the induced signal that sensor circuit 204 is used to receive and the identification user imports in induction planes 201 touchings, and export signal accordingly, sensor circuit 204 can calculate contact position according to the difference of four corner ratios of current distance.Below induction planes 201, there are two control buttons 202 to be respectively emulation right mouse button function and left mouse button function.And a wireless module 210 is arranged in wireless Trackpad 200, the signal of sensor circuit 204 output is sent in the wireless receiver module 140 in the portable information processing device 100 by a direction-free embedded antenna 220, so the induced signal that is produced in induction planes 201 touchings just can produce action or assign execution command to display interface 160 cursors of portable information processing device 100.
In addition, also have a remote control module 250 in the wireless Trackpad 200 of the present utility model, utilize in one guide rail 260 that remote control module 250 is entered in the wireless Trackpad 200 in can be smooth and easy slidingly, pull out again during use.Remote control module 250 is provided with a plurality of function buttons 251, function button 251 in order to move instruction to portable information processing device 100, to carry out command function corresponding to this function button 251, button 251 parts are built-in function, as sound size, switching on and shutting down or skip to down the instruction of one page etc., the function button 251 that part is also arranged is to utilize the routine plan configuration, allows the user can fast carry out some specific action.Remote control module 250 also is to utilize frequency microwave (RF) with portable information processing device 100, and 802.11b and 802.11g communication protocol in blue teeth wireless (bluetooth) or the wireless transmission protocol are done wireless transmission.At this, use above-mentioned radio transmitting method, than the telepilot that uses general use infrared technology, in its operation, not limited by space angle.
Please refer to Fig. 4, be Trackpad wireless transmission process flow diagram of the present utility model, in the step 401, when the user is separated wireless Trackpad 200 by portable information processing device 100, the startup that is triggered of wireless Trackpad 200, enter step 402 this moment, wireless receiver module 140 around wireless module 210 begins to search, step 403, confirm online after, send an indicator signal, this indicator signal is set up the online of 100 of a wireless Trackpad 200 and portable information processing devices, in the step 404, this sign begins to carry out the transmission of data after confirming, the user touches the track of drawing at wireless Trackpad 200 and will transfer the track that mouse moves to and be shown on the display interface 160, in like manner, remote control module 250 selected function button 251 signals also will import in the portable information processing device 100 and carry out.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the utility model claim.
