Wherein a chamber is formed inside the main body, the main body has a first plate and a second plate, the main body forms an inlet channel and an outlet channel, so that the cooling water passes through the chamber. The first fin set and the second fin set are arranged in the chamber, and the first fin set and the second fin set are connected to the first plate respectively. The first fin set comprises several first fins spaced apart, the first fins divide the chamber to form several first channels. The second fin set comprises several second fins spaced apart, the second fins divide the chamber to form several second channels. The water cooling head can increase the overall heat sinking efficiency.

Abstract: A dispensing device, having a hollow nipple-shaped stopper configured to act as a one-way valve, for use as a hair dyeing comb is provided. The nipple-shaped stopper has an aperture at its tip end. The aperture opens toward outside when the operator compresses the plastic bottle and closes when the operator releases the plastic bottle. When the aperture is in its closed position, the stopper prevents the liquid hair dye already in the conduit from flowing back to the plastic bag inside the bottle. The purpose of using the stopper here is to keep the air out of the dispensing system in order for the operator to pump the liquid dye efficiently. The stopper and a small aperture at the bottom of the plastic bottle are replacing the one-way valve currently used in many hair dye-dispensing devices. With interchangeable comb heads, the operator can choose the proper comb head for his hair type and different application purpose.

The image input interface is used for receiving an image data stream. The buffer is coupled to the image input interface and used for temporarily storing the image data stream. The storage media interface is coupled to external storage media and the buffer and used for sending an image data stream stored in the storage media to the buffer for display, or sending an image data stream stored in the buffer to the storage media for storage. The direct memory access buffer controller is used for increasing a data access speed between the storage media interface and the buffer.

Abstract: An image capture and display system contains a three-stage digital gamma correction circuit. Three equations are used to determine the gamma correction characteristics for low intensity, medium intensity, and high intensity signal levels, respectively. Linear correction is used for low and high intensity levels, and an adjustable non-linear correction is used for medium levels. The resultant effects of the combined correction characteristics are to increase the effective Signal-to-Noise ratio for low level signals, enhance the gray level differentiation for high level signals, and heighten the contrast control for medium level signals. In addition, the contrast control is effective throughout the entire range of signal intensity levels. The image capture and display system provides a high quality visual display, with a simple, economical hardware implementation of the inventive gamma correction circuit.
