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 method for increasing signal to noise ratio is disclosed. The method can automatically detect saturation output voltage of the photosensors via adjusting exposure time or illumination intensity so as to obtain optimum output voltage of the photosensors as well as high signal to noise ratio that can generate high quality images.

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.

Abstract translation: 手车具有底架，手柄组件，两个轮架，多个轮子和两个杠杆。 手柄组件可伸缩地连接到基架上。 每个车轮支架用枢轴销枢转地附接到基座的一侧。 至少一个车轮可旋转地安装在每个车轮支架上。 每个杠杆的一端枢转地连接到每个枢轴销，另一端可操作地连接到手柄组件。 因此，当手柄组件移动到扩张位置或缩回位置时，具有轮子的轮支架将通过杠杆的传动而自动缩回或膨胀。 具有手车的对象的大小可以最小化。 另外，避免室内脏污。
