Abstract
In order to prevent or at least difficult inappropriate range readjustment of the operational parameters of a device, readjustment is limited by a value interval, whose mean value is adapted to the momentary value of the operational parameter. Readjustment of operational parameters which are subject to changes caused by aging or slow environmental influences are thus substantially simplified. This is particularly advantageous when readjusting the operational parameters of a display device, for instance the power supply voltage of a color LCD display, since in pactice, it prevents a user from rendering a display unusable as a result of inappropriate readjustment.
Description
The equipment that much can buy at present is made of display device, and when using a kind of input media, for example a keyboard can be adjusted on equipment and can be modified by means of it.For example such equipment is communication terminal equipment, particularly the mobile radiotelephone communication terminal equipment.Owing to this display device of reason is physically standing ageing process, it makes one of this display device supply voltage to adjust again, particularly on LCD, becomes necessary.
Exist possibility here, the user is owing to be ignorant or fault has been carried out one and adjusted, and caused can not re-using of display device.Just produced problem then, on equipment one further adjust handle or adjust change be actually no longer may because the whole users' guidebook of this change or adjustment and feedback must be finished through present out of use display.Consequently in fact the user can only rely on Service Technicians's the support of his equipment manufacturers in this case.
The situation of an all fours is also arranged on other fully equipment, and equipment provides operational factor, and operational factor must be adjusted again in case of necessity.Also exist danger here, owing to one of operational factor unprofessional adjustment with adjust an equipment state again and be adjusted, can not obtain a result by adjusting oneself again thereby may produce certain danger or user therein.
For fear of this problem, the present invention has considered to have an equipment of the device of adjusting at least a operational factor again according to the feature of claim 1.
For fear of or an equipment operation parameter in an inappropriate scope is adjusted again cause difficulty, the present invention to consider, adjust the restriction that is subjected to an interval of values again, the moment numerical value of the mean value of interval of values and operational factor is complementary.Thereby particularly the adjustment again of operational factor becomes simply, because the change of aging or environmental impact slowly is overcome.This advantage that has especially is then, if adjust when relating to operational factor of a display device again, for example relate to the supply voltage of the LCD-display of a colour, because from then on avoided actually, a user is because unprofessional adjustment again can not re-use display device.
Corresponding and confers similar advantages is developed on other equipment according to solution of the present invention, the operational factor of these equipment must be adjusted.
Following the present invention is narrated by means of advantageous embodiments.
The present invention is from a kind of equipment, the device that it provides at least one operational factor of this equipment to adjust again.This can be analog regulator or input keyboard, depends on the time of button or the numerical value of a parameter of number can be changed with it.The present invention has considered that now adjusting again of an operational factor or a plurality of operational factors is restricted by an interval of values, and it is by an interval width with by a mean value definition.
May be positioned within the interval of values as adjusting the parameter value that is provided use again, interval of values is launched around a mean value in an interval width.Thereby to provide parameter value as the minimum of adjusting again to be that mean value reduces the half interval width and the operational parameter value as the maximum of adjusting again is provided be that mean value increases the half interval width.Suitable is is stored in the interval width and the mean value of an interval of values in the equipment.Interval width can be stored in oneself a memory storage of for this reason arranging or as a software parameter.
Now in order to guarantee, when a structure member of equipment or equipment wears out, it makes an adjustment of operational factor is necessary, the position of interval of values can be complementary with reformed requirement, the present invention has arranged, the mean value of an interval of values or the mean value of a plurality of interval of values are stored on the memory storage of equipment like this, and it is possible, and promptly stored mean value or stored mean value are rewritten with the parameter value of moment.
This measure makes it to become possibility, and the interval of values position corresponding coupling is possible when object changes at leisure, though final like this owing to wearing out or because the change that environmental impact causes is possible all the time, adjusting the necessary parameter value.Yet also avoided simultaneously, king-sized or especially little parameter value can unconsciously be adjusted.
Can speak of the window (interval of values) of a so-called slip with other saying people, in this scope with interior possible, to operational factor stepless or adjust with several levels.Thereby impossible, in a significant or reliable range of parameter values, come out.Thereby particularly have under the display device situation and guaranteed when equipment, can not need the supply voltage of display is carried out an adjustment, this is that of display reads and can not accomplish.
Considered in an advantageous embodiments of the present invention that now the parameter value of moment promptly is introduced into the new mid point as the numerical value window as the new mean value of interval of values.Thereby can be implemented in the very big setting range (range of balance) in the life span.Be unlikely to because the faulty operation display becomes and cannot read again.
This is particular importance in colour-LCD-display particularly, because ageing process depends on environmental baseline, for example too high or too low for temperaturely can cause big color change here.This can finally cause the not readable property of display.Be performed such by the present invention correspondent voltage balance, color change can be feedbacked all the time again, be unlikely to produce dangerous, display since a faulty operation or the mistake adjustment when adjusting again temporarily or for good and all become and not can read.
The present invention has considered to have at least one operational factor a kind of equipment of adjusting gear again in its citation form, wherein the adjustment again for an operational factor provides an interval of values, its mean value is stored in the memory storage, wherein stored numerical value can be rewritten with the moment numerical value of operational factor, thereby its new numerical value has determined the position of interval of values after once the reading again of stored mean value.
Additionally in equipment, stored the mean value of adjusting aspect the factory according to a favourable form of implementation of the present invention immutablely, rewrite with the mean value that the stored mean value of moment can recruitment manufacturer face be adjusted, like this after once the reading again of stored mean value aspect the factory mean value of adjustment determined the position of interval of values.
Particularly when equipment has a display device, its operational factor should be adjusted again, an other form of implementation advantageous particularly of the present invention, acting on when adjusting again that the supply voltage of display device is adjusted again can be observed by the user, because shown a test image on display device when adjusting again.
Related to this is the form of implementation advantageous particularly of a special use of the present invention because display is colored, thereby test image when adjusting again with different color display surface or object, its colour is changed by adjusting again.
Produce a particularly advantageous operation of equipment then, if stored mean value is rewritten with the moment numerical value of corresponding operational factor when disconnecting, then its numerical value is read as new mean value when reclosing.
In order to realize that the present invention has only considered a storage possibility of interval of values mean value in an equipment, wherein considered possibility, depended on certain use-or operational circumstances or rewritten with the parameter value of moment according to this stored numerical value of working of an invention form separately by closing device.Considered then according to the working of an invention form that separately moment storage in equipment when reclosing equipment is new mean value sometimes to be read and to be used as the new mean value of an interval of values.
