Abstract: A power management apparatus and a power management method are provided. The method includes the following steps. Conduct a first current path during a first period. Provide a first voltage to an operation end when the first current path conducts and a microprocessor is disabled. The first voltage is used to selectively conduct a second path during the first period. Provide a second voltage to the microprocessor when the second current path conducts. The second voltage is used to turn on the microprocessor. Provide a third voltage to the operation end by the microprocessor when the microprocessor is turned on. The third voltage is used to keep the second current path conducted.

Abstract: The disclosure provides an active stylus pen and signal transmission methods for the active stylus pen and a touch panel. The stylus has a touch module, a switching module, a signal comparison module, a control module and a pressure sensing module. The stylus determines a first signal generated by a touch panel, and compares an intensity of the first signal and a reference value through a first transmission path. When the intensity of the first signal exceeds the reference value, the stylus outputs a second signal to the touch panel. After the stylus outputs the second signal to the touch panel, the stylus switches to a second transmission path from the first transmission path. The stylus outputs a header signal to the touch panel. When determining a first time sequential distribution, the stylus outputs at least one bit of a pressure signal according to a second time sequential distribution.
