Abstract: An interpolation method for generating pixel color is used for color generating of an array composed of red, green, and blue pixels so that each pixel has red, green, and blue components. After signals of the pixel array are received, the signal trends in the horizontal and vertical directions around pixels are first determined. Next, two pixels adjacent to each pixel are calculated along the direction of minimum variation to complement data of the pixel location using this calculated value. Subsequently, the lost blue or/and red component of each pixel is generated for pixels in the horizontal and vertical directions so that each pixel has red, green, and blue components. Accurate color interpolation can thus be provided to accomplish the effect of high and stable resolution.

Abstract: A writing implement with ornament having an ornament plate assembled from a body and a cover plate installed on a penholder of a conventional writing implement. A slide piece, a set of gears and an ornament member are installed interior of the ornament plate. When writing with the writing implement and pressing down on the penpoint, the pen refill pushes the slide piece upward, which rotates the set of gears and compresses a spring, thereby effecting vertical displacement of an ornament on the ornament member.

Abstract: A pen with a swinging decoration includes a decoration in a shape with two hands and two legs at a top end of a penholder of an ordinary pen. A refill is pushed against a top shaft to move upward and pressed against a swing, whereas teeth rows at two edges of the top shaft drive conjugate gears to rotate at the same time, so as to swing the two hands and two legs having gears upward and downward at the same time, upon writing with the pen.

Abstract: A wavelength division multiplexer (WDM) and a type of fiber arrangement for the WDM are provided. In the WDM according to the invention, a filter having dielectric coating is used to allow lights within a specific band of wavelength to pass but reflect lights not within the specific band of wavelength. A reflection mirror is then used to reflect the lights passing through the filter to pass through the filter for a second time. Because of the two filtering, the WDM provided by the invention has very high adjacent channel isolation. In particular, the WDM contains a fiber pigtail having a fiber bundle and a ferrule with a square aperture in the center. By carefully arranging the common input fiber, the reflection output fiber, and the transmission output fiber inside the aperture, the lights in the specific band of wavelength have identical wavelength bandwidth when passing through the filter twice, and the insertion loss for both the transmission output and the reflection output is minimum.

Abstract: A system for measuring the stability of a power signal from a power supply includes a threshold violation detector. The threshold violation detector includes a comparator and an indicator. The comparator has a power signal input, a threshold signal input, and a comparison result output, and is configured to compare the power signal on the power signal input with a threshold on the threshold signal input to present a comparison result signal on the comparison result output. The indicator has a threshold violation output and a comparison input that receives the comparison result signal from the comparator. The indicator presents a threshold violation signal on the threshold violation output when the comparison result signal indicates that the power signal has violated the threshold.

Abstract: A CPU heat exchanger comprises a plurality of curved metal thin pieces, each surface of each metal thin piece having punched with a plurality of ribs, the ribs at opposite sides being alternatively arranged; so that a trench is formed between two metal thin pieces for being formed with a turbulent flow; each rib having openings at an upper side and a lower side thereof. Airflow in the trench is turbulent and thus, air therein can absorb much heat. The openings on the upper and lower sides of each ribs cause air therein to expand and thus the heat can be absorbed more quickly. Therefore, cool and hot air are exchanged quickly.
