| 20090302827 | Sensing circuit and method for a flyback converter - A flyback converter includes a transformer to convert an input voltage into an output voltage, a control circuit senses a primary current of the transformer to generate a current sense signal, and a sensing circuit is configured to sense a variation of the current sense signal between two time points for extracting the input voltage information therefrom. | 12-10-2009 |
| 20090303756 | Maximum output power control of a flyback converter - A method and apparatus for a flyback converter estimate the next value of the current limit for the flyback converter according to a present current limit value to achieve the maximum output power control of the flyback converter. An arithmetic circuit is used to calculate the next current limit value according three parameters, the present current limit value, the value of the current sense signal taken after a first time period counting from the instant when the present duty is triggered, and the variation of the current sense signal during a second time period, thereby narrowing the tolerance of the output power from the flyback converter. | 12-10-2009 |

| 20080310192 | Output power limit for a switching mode power converter by a current limit signal having a multi-slope waveform - A current limit signal having a multi-slope waveform is provided for a power converter that has a power switch switched to convert an input voltage to an output voltage, for output power control more preciously. The current flowing through the power switch has a maximum value being a function of a duty cycle of the power switch when the power converter operates at a constant output power condition. The current limit signal is generated according to the function, and is compared with a sensing signal produced from the current flowing through the power switch, so as to turn off the power switch if the sensing signal is not lower than the current limit signal. | 12-18-2008 |

| 20110113426 | APPARATUSES FOR SWITCHING THE RUNNING OF A VIRTUAL MACHINE BETWEEN MULTIPLE COMPUTER DEVICES BELONGING TO THE SAME COMPUTER PLATFORM AND THE ASSOCIATED SWITCHING METHODS - An apparatus for managing a running virtual machine on a desktop or laptop platform includes a first computer device, a second computer device and a shared memory. The first computer device has a first switching hypervisor on which a virtual machine runs. The second computer device has a second switching hypervisor, wherein the second switching hypervisor is in communication with the first switching hypervisor. The shared memory is coupled to the first and second computer devices, and is accessible by the first and second switching hypervisors, wherein the first switching hypervisor stores status information of the virtual machine into the shared memory. When receiving a switching notification for switching the virtual machine to run on the second computer device, the first switching hypervisor halts its running of the virtual machine, and then the second switching hypervisor obtains the stored status information of the virtual machine from the shared memory and resumes the running of the virtual machine on the second computer device according to the obtained status information of the virtual machine. | 05-12-2011 |
