    Abstract: A method for detecting a single-finger rotation gesture and a gesture detecting circuit thereof are provided. The gesture detecting circuit comprises a quadrant dividing unit, a register, a control unit, a comparing unit, and an outputting unit. The quadrant dividing unit, according to the center point, divides a touch panel into at least three quadrants and sets a plurality of data codes respectively corresponding to the quadrants. Within a predetermined time, the control unit controls the register to sequentially record the data codes respectively corresponding to the touched quadrants. When the predetermined time is reached, the comparing unit compares to judge whether the temporary data buffered in the register is the same with the default data. If the temporary data is the same with the default data, then the outputting unit outputs a rotation gesture signal.

    Abstract: A method for double click detection includes the following steps. Firstly whether first event is detected is determined, if so, first corresponding position is obtained, a period counting is triggered, and first flag is set. Then whether the period ends is judged; if not and the first flag exists, a counter is incremented and second flag is set when first ending event is detected; if not and the second flag exists, second corresponding position is obtained and third flag is set when second event is detected; if not and the third flag exists, the counter is incremented when second ending event is detected; if so, a double click event is determined when the incremented value is greater than a threshold and a distance between the first and the second positions is smaller a threshold.

    Abstract: A family of Li-ion battery cathode materials and methods of synthesizing the materials. The cathode material is a defective crystalline lithium transition metal phosphate of a specific chemical form. The material can be synthesized in air, eliminating the need for a furnace having an inert gas atmosphere. Excellent cycling behavior and charge/discharge rate capabilities are observed in batteries utilizing the cathode materials.
