Embodiment

Below in conjunction with accompanying drawing the utility model embodiment is described in detail.

Please refer to shown in Figure 1, the utility model embodiment provides a kind of state exchange triggering system of handheld terminal, mainly comprise writing pencil, writing pencil condition checkout gear, processor and application program module, described writing pencil condition checkout gear is arranged between described writing pencil and the processor.Its basic principle of work is: " writing pencil condition checkout gear " detects the current state of writing pencil is to extract or insert, and current status information is sent to the processor of handheld terminal, processor is made corresponding action according to the setting of end application module, i.e. the conversion of state (as program definition user action can be set and then make the action that the user is provided with) starts corresponding function.

For example, writing pencil is extracted from a groove, " writing pencil condition checkout gear " detects the current state of writing pencil is to extract, then processor can be transformed into duty from holding state according to the setting handheld terminal of application program module, opens (perhaps the carrying out one or more action of the control able to programme of user's setting) backlight of handheld terminal screen; Equally, when turning round and stretching out the hand hand-written penholder in the groove of holding terminal, " writing pencil condition checkout gear " detects the current state of writing pencil is to insert, then processor can be transformed into holding state from duty according to the setting handheld terminal of application program module, closes (perhaps the carrying out one or more action of the control able to programme of user's setting) backlight of handheld terminal screen.

And for example, writing pencil is extracted from a groove, " writing pencil condition checkout gear " detects the current state of writing pencil is to extract, and then processor can start the handheld terminal working procedure according to the setting of application program module, as writes note; Equally, when turning round and stretching out the hand hand-written penholder in the groove of holding terminal, " writing pencil condition checkout gear " detects the current state of writing pencil is to insert, and then processor can cut out the function interface that all are moving according to the setting of application program module.

Application program module also comprises alarm module in the present embodiment, if detecting writing pencil over time, the writing pencil condition checkout gear still is in the state of extracting, then this status information is sent to processor, after receiving, processor judges it is that the user does not in time turn back to writing pencil a groove, then sending controling instruction is given alarm module, start warning function, send caution to the user, lose to prevent writing pencil to dodge modes such as screen, vibrations, bell sound.

Above-mentioned state exchange can also be to be converted to duty, holding state or other programmable functions state.The user needn't click screen or just can Ji Huozhongduan ﹠amp by specific button again; Make terminal standby to sleep pattern, perhaps carry out user-defined action.

Writing pencil condition checkout gear based on above-mentioned principle roughly has four kinds:

1, first kind: adopt mechanical switch to cooperate the writing pencil of any materials.

2, second kind: adopt HALL (Hall) switch to cooperate the magnetic writing pencil.

3, the third: adopt tongue tube to cooperate the magnetic writing pencil.

4, the 4th kind: adopt light detecting device to cooperate the writing pencil of any materials.

5, other can detect the device of writing pencil state, for example adopts pressure sensor cooperate any writing pencil, adopt capacitive transducer to cooperate generally be metal or part comprise metal writing pencil or or even adopt oscillation circuit complexed metal writing pencil (in order to guarantee the reliable of this kind detection, generally to adopt the bigger material of magnetic hysteresis, such as materials such as steel or nickel matter) etc.

Be example to adopt simulation output HALL (Hall) switch to cooperate the magnetic writing pencil and be transferred to processor below, its principle of work and process are described by the GPIO interface.

Please refer to shown in Figure 2ly, magnetic material 2 is embedded in structural design in the writing pencil 1, Hall element 3 positions in structural design then near the position of magnetic material 2.

When writing pencil 1 is inserted in the terminal writing pencil slot, magnetic material 2 is near Hall element 3, Hall element 3 is sensed the magnetic force of magnetic material 2, its output state is that (annotate: output is subjected to the parameter of the actual Hall element of selecting for use 3 different and different to A, its output state can be analog variation signals such as the rising of voltage, electric current, this bulk resistor etc. or reduction, also can be corresponding digital signal (digital signal wouldn't be described, and only describes the analog signal form of front)).Shaping circuit 4 changes into digital signal C (high level (H) or low level (L)) to the output state of Hall element 3, and transfer to processor 6 by GPIO interface 5, processor 6 detect that GPIO interface 5 transmits state, judge that this moment, writing pencil was positioned at the insertion state, processor 6 moves output order to executive circuit 7 according to the setting of application program module 8, the action (such as closing display backlight etc.) of action that executive routine is set or user-programmable control.

When writing pencil 1 is extracted the writing pencil slot, magnetic material 2 in the writing pencil 1 is away from Hall element 3, Hall element 3 inductions are less than the magnetic force of magnetic material 3, output state is converted into the inverse state B of A condition (if A condition is voltage, electric current, the rising of this bulk resistor etc., then the B state is a voltage, electric current, the reduction of this bulk resistor etc., if A condition is voltage, electric current, the reduction of this bulk resistor, then the B state is a voltage, electric current, the rising of this bulk resistor), shaping circuit 4 changes into digital signal D (high level (H) or low level (L) to the output state of Hall element 3, if the C signal is a high level, then this moment, the D signal was a low level; If the C signal is a low level, then this moment, the D signal was a high level), and transfer to processor 6 by GPIO interface 5, processor 6 detect that GPIO interface 5 transmits state, judge that this moment, writing pencil was positioned at the state of extracting, processor 6 moves output order to executive circuit 7 according to the setting of application program module 8, the action (such as opening display backlight etc.) of action that executive routine is set or user-programmable control.

Be understandable that, shaping circuit 4 is used for the detected status information of writing pencil condition checkout gear is converted to the information that processor can be discerned in the present embodiment, comprise the circuit that signal is carried out shaping or conversion, for example circuit such as the mutual conversion of simulating signal and digital signal, the mutual conversion between the distinct interface standard digital signals, signal level conversion.If processor can be discerned the detected status information of writing pencil condition checkout gear, then can omit shaping circuit 4.For example, if pick-up unit (can detect the device of writing pencil state arbitrarily, such as Hall element or pressure transducer etc.) is digital output type, processor 6 can be discerned, then can omit shaping circuit 4, directly give processor 6 by GPIO interface 5 transmission signals.

If pass through other interfaces (such as I2C, PCMCIA, USB etc.) transmission signals, then can select for use directly and self directly give processor by corresponding interface transmission signals with the detecting element of one of above-mentioned interface, convert to after also can selecting for use the detecting element of simulation output or numeral output to handle and meet corresponding interface specification data information, give processor 6 by corresponding data-interface transmission signals again through shaping circuit 4.Should be understood that the interface that present embodiment adopted is to be used to make between pick-up unit and the processor to transmit data smoothly, kind is not limited in the literary composition mentioned, comprises arbitrary standards or self-defining data or state interface.
