Abstract: A power supply circuit includes a first regulator and a second regulator. The first regulator is configured to generate a first output signal according to an input signal. A voltage value of the first output signal decreases according to the input signal and a first voltage threshold value at a power-off stage. The second regulator is configured to be enabled according to the first output signal to generate a second output signal according to the input signal. A voltage value of the second output signal decreases according to the input signal and a second voltage threshold value at the power-off stage. The second voltage threshold value is greater than the first voltage threshold value.

Abstract: An expandable function data storage device includes a first main body and a second main body. The first main body has a memory circuit unit. Its first end is exposed outside and has a first signal communication port and its second end has a second signal transmission port. The second main body has a reception space and can be sleeved on and connected to the first main body, to protect the first signal transmission port. Specifically, the second main body includes an application circuit unit, and a third signal transmission port is provided in the reception space. When the second main body is sleeved on and connected to the second end of the first main body, the second signal transmission port is electrically connected to the third signal transmission port, so that the memory circuit unit may transmit/receive data to/from the application circuit unit.

Abstract: A method and system of zooming digital images is disclosed. By marking one or more coordinates with the index (for instance, cursor) in a display area, thus a position base can be defined. After a zooming ratio chosen by users or generating depending on the marked coordinates is decided, the display area renews with a zoomed image according to the position base and the zooming ratio. Comparing with continuously shifting the zoomed image for positioning, a lot of computing and hardware cost can be saved.
