  • PORTABLE ELECTRONIC SYSTEM AND TOUCH FUNCTION CONTROLLING METHOD THEREOF
    Publication number: 20140152598
    Abstract: A portable electronic system includes a display module, a touch input module, and a control module. The touch input module includes a touch panel, a transceiver control unit, and a touch processing unit. The transceiver control unit is coupled with the touch panel to transmit signal. The touch processing unit is coupled with the transceiver control unit. The control module includes a sensor and a control unit. The sensor detects an open or closed state of the display module to output a sensing signal. The control unit is coupled with the sensor to enable or disable the touch input module according to the open or closed state of the display module when the portable electronic system is at an operating mode.

  • Computer system capable of dynamically modulating operation voltage and frequency of CPU
    Patent number: 8296597
    Abstract: A computer system capable of dynamically modulating an operation voltage and an operation frequency of a CPU comprises: a CPU from which a VID1 is outputted based on a real load of the CPU; a VID converting/comparing controller capable of determining to operate in an bypass mode or a calculation mode in response to the received VID1 signal and capable of outputting a VID2 signal and a control signal; a frequency generator for generating a CPU clock with a specific frequency to the CPU in response to the control signal; and a PWM controller capable of generating the operation voltage to the CPU in response to the VID2 signal; wherein when the VID converting/comparing controller is switched to operate in the calculation mode, the VID1 signal is not equal to the VID2 signal and the specific frequency is modulated to either a higher or a lower than a normal operation frequency by the VID converting/comparing controller.
