Abstract: A light-emitting diode (LED) light source control method is disclosed. The light-emitting diode light source control method is used for controlling a composite and a single color LED light source. The composite color LED light source can provide two of the three original red, green and blue color lights and the single color LED light source provides the third original color. The composite and the single color LED light sources provide illuminations sequentially so that the light sources need not to be turned on continually and the data generated by the composite and the single color lights on the red, green and blue channels of image sensors can be processed sequentially.

Abstract: A full-zone optical image addressing apparatus, including an addressing device, an image extraction converter, a comparator, an AND gate and a counter. The addressing device is located at the enclosure of the scanner and includes a plurality of geometric patterns. Each of the geometric patterns includes a plurality of rows of pixels. While receiving an exposure signal, the image extraction converter extracts one row of pixels from the addressing device, such that a series of analog signals is obtained and output to the comparator. The comparator then compares the series of analog signals to an analog critical voltage to output a series of analog comparison signals to the AND gate. The AND gate synchronously processes the series of analog comparison signals and a pixel rate clock to output the pixel data corresponding to the extracted row of pixels to the counter. After receiving the synchronously processed pixel value from the AND gate, the counter calculates and outputs the extracted row of pixels, including the amount of pixels and the geometric patterns in the row of pixels.

Abstract: A handcart has a base frame, a handle assembly, two wheel brackets, multiple wheels and two levers. The handle assembly is retractably connected to the base frame. Each wheel bracket is pivotally attached to one side of the base frame with a pivot pin. At least one of the wheels is rotatably mounted on each wheel bracket. One end of each lever is pivotally connected to each pivot pin, and another end is operationally connected to the handle assembly. Accordingly, the wheel brackets with the wheels will be automatically retracted or expanded through transmissions of the levers when the handle assembly is moved to an expanded position or a retracted position. The size of an object with the handcart can be minimized. In addition, getting the indoors dirty is avoided.
