Abstract: Image interpolation is becoming an increasingly important topic in digital image processing, especially as consumer digital photography is becoming ever more popular. From enlarging consumer images to creating large artistic prints, interpolation is at the heart of it all. This invention present a new method for image interpolation, which produces high quality results, yet it's speed is comparable to polynomial interpolation (i.e. cubic interpolation).

Abstract: For graphic artists, medical image specialists, image processing researchers, and many others, the ability to apply the same view and drawing tools to multiple opened windows (i.e. images in windows) is a must. This invention describes a method where in a multiple document interface application the views and drawing tools information is sent out to all opened windows in the parent application so that images in different windows can be synchronized with the image in the active window.

Abstract: A pen for hand-writing recording using an assembly of accelerometers. The accelerometers provide a three dimensional acceleration vector which together with a clock determines the position of the pen at all times. In addition, a sensor on the pen records when the pen is being pressed against a hard surface and it is only then that the pen records the movements of the pen and hence the hand-writing. The writing can be recorded by the pen for later download to a computer system, or the pen can be directly connected to a personal computer, thus providing a a true mouse-type pointing device that does not require any additional tables or touch-pads for two dimensional drawings.

Abstract: A computer mouse used to control the monitor screen, having only two contacts (the minimum possible contacts). The spherical ball is in touch only with the coordinate shafts. The third contact, necessary for ball stability, is replaced with a magnet which will engage the ball with the coordinate shafts. The magnet will not touch the ball.

Abstract: Procedure for digital picture edge-smoothing refers to a method of smoothing the rough edges, around the objects, in a digital picture, as a result of enlargement. The procedure consists of detecting the rough edges and removing some pixel(s), so that edge will become smoother. If the edge has a 45 degrees angle, made of 2 by 2 pixels, will become an edge of 1 by 1 pixel. If the edge has 4 by 2 pixels, it will become a 2 by 1 pixel edge.

Abstract: A procedure to attach securely a lamp on a ceiling allowing easy electrical connection and the use of a lamp with the most elegant upper end. This is possible by using a spring to support the lamp, which will allow to pull down the lamp in order to do the electrical connection. The electrical wires come through ceiling and are covered by the upper end of the lamp. The lamp released will be pressed against the ceiling by the spring.

Abstract: This invention describes a new method for flying in the air or moving in the water. The flying machine comprises of two or more umbrellas that move vertically on a shaft in a sequential manner and are powered by an external force. Each umbrella has a blade surface composed of blades which can be closed or opened. Each umbrella also has a lateral surface connected with its blade surface. The blade surfaces of each umbrella can be circular or rectangular.

Abstract: A high resolution multi-flash analog-to-digital converter comprised of multiple small resolution full-flash analog-to-digital converters combined in such a manner as to generate a higher resolution digital voltage. The first small resolution analog-to-digital flash converter will generate the lowest order bits of the multi-flash analog-to-digital converter. The second small resolution analog-to-digital flash converter will generate the next higher order bits of the multi-flash analog-to-digital converter, and so on, until the last small resolution analog-to-digital flash converter will generate the most significant order bits of the multi-flash analog-to-digital converter.
