Abstract: A method for preventing a misoperation on an edge of a touch screen includes: determining a first touch region according to touch operation on an edge of a touch screen; forming a second touch region according to coordinate information of touch points in the first touch region; forming a third touch region according to a longest column in the second touch region and a column on a left side of the longest column if the touch points in the second touch region are arranged as parallel to a right edge of the touch screen; judging whether a length-to-width ratio of the third touch region is less than or equal to a predetermined threshold; and determining that the touch operation is a misoperation if the length-to-width ratio is greater than the predetermined threshold.

Abstract: Disclosed are floating state determination and floating compensation methods and apparatuses for a touch screen. The floating state determination method includes: performing two times of self-capacitance interlaced driving on the touch screen in each of a driving direction and a sensing direction; calculating self-capacitance differences corresponding to the two times of self-capacitance interlaced driving in each of the driving direction and a sensing direction, and obtaining an interlaced differential value of each channel based on the self-capacitance differences; and calculating a self-capacitance differential value of each channel, and determining a floating level of the channel based on the result of calculation. The floating state determination method can determine a floating state of the touch screen, and then a floating compensation is performed based on the floating state, so that the capacitive screen can be operated normally under floating.

Abstract: A Toona sinensis extract for antibacterial. The Toona sinensis extract has the ability to inhibit growth or reproduction of bacteria and also to prevent corruption, color change and acidification of foods. So that, it can replace commercial ingredients and be applied to antibacterial, pharmaceutical composition or preservative that can prevent food corruption.
