Abstract: A fiber reinforced composite is formed using a shrinkable die. A composite of fiber and resin is placed in the die and is compressed by shrinking the die to form a desired transverse cross-section. Optionally, the die is bent along its lengthwise extent to shape the composite in the die. After shrinking and optional shaping, the composite is cured to form the fiber reinforced composite.

Abstract: A method for forming an orthodontic device having a fibre reinforced composite is provided. The fibre reinforced composite has a fibre material within a matrix phase material. The fibre material comprises braided fibre material having a braid angle in the range from about 3° to about 87°, and more particularly in the range from about 10° to about 45°. The fibre reinforced composite is formed from a method which includes the steps of impregnating the fibre material with a monomer resin, shaping the fibre that is impregnated with the resin into a defined cross sectional shape suitable for use in the orthodontic device, and polymerising the monomer resin in the impregnated fibre to form the fibre-reinforced composite.

Abstract: Architecture for providing serial RGB data to be displayed in the panels with the delta arrangement of pixels is provided herewith. In the architecture, data sequence transmitted from an application specific integrated circuit (ASIC) to a panel of a device is modified to avoid the problem of saw-toothed images, which can improve the quality of displayed images. In the architecture, the image data is received for the panel and is converted to serial RBG data. The data sequence of the serial RGB data either for the pixels at an odd line or for the pixels at an even line of the delta arrangement in the panel is adjusted to avoid the problem of saw-toothed images.

Abstract: A method for manufacturing a power bus on a chip, where the power bus has slits generated therein. The present invention relates to a method to manufacture a power bus in which the reference to a layout data base shows the coordinate location of the power buses in the chip. A height and width for the power bus is calculated based on its coordinates. Based on the height and width of the power buses and the predetermined size and spacing between power slits, a number of power slits to be generated is determined. These power slits are then generated by adding the power slits to the power bus in the coordinates of the layout database. The method of the present invention also generates power slits for use in manufacturing power buses on a chip for cases in which the power buses overlap.

Abstract: A microelectronic device according to the present invention is made up of two or more functional units, which are all disposed on a single chip, or die. The present invention works on the strategy that all of the functional units on the die are not, and do not need to be operational at a given time in the execution of a computer program that is controlling the microelectronic device. The present invention on a very rapid basis (typically a half clock cycle), therefore, turns on and off the functional units of the microelectronic device in accordance with the requirements of the program being executed. This power down can be achieved by one of three techniques; turning off clock inputs to the functional units interrupting the supply of power to the functional units, or deactivating input signals to the functional units.
