摘要： A self-adaptive image-based obstacle detection method comprises steps: capturing an original image; transforming the original image to an HSV color space, and retrieving a hue component (H) and a saturation component (S) of the HSV color space to form an HS-based image; dividing the HS-based image into image blocks; selecting one image block as a background block; using an obstacle recognition equation to determine whether each of the image blocks is similar to the background block; if no, deleting the image block; if yes, preserving the image block to form a binary obstacle image; and overlaying the binary obstacle image on the original image to filter out the background and obtain an initial ambit of an obstacle image. Then, three orderly movement flow equations are used to determine whether it is an obstacle.

摘要： An automated power supply is formed primarily by electrically connecting a power supply system and a chip management module. The chip management module includes a data storage module, a transmission module, a protocol circuit module and a power detecting module. The protocol circuit module includes at least one power output/input pin for transmitting an electric signal, and a grounding pin. Therefore, not only a requirement of an internal driving power can be reduced, but also a size of the chip and electric power consumption can be diminished significantly.

摘要： Signal compensation systems and methods. The system comprises a sensor and a processing module. The sensor detects movements of a camera device to generate sensed signals. The processing module acquires a relative maximum value and a relative minimum value of the sensed signals, and calculates an absolute difference accordingly. The absolute difference is the absolute value of the relative maximum value added the relative minimum value. The processing module determines whether the absolute difference exceeds a predetermined value. If so, the sensed signals are identified with a drift, and compensated according to the absolute difference.
