Abstract: Disclosed are super broadband circularly polarizing film materials and novels methods of fabricating and using the same.

Depending on the final spiral structure of the polymeriable CLC materials utilized, the CLC circularly polarizing materials reflect either left-handed or right-handed circularly polarized light.

Abstract: The object of the present invention is to eliminate the flicker of an LCD/Micropol assembly by reducing the excess heat caused by the attachment of the Micropol to the LCD. The present invention solves the problem of LCD flicker caused by excess heating of the LCD/Micropol assembly by reducing the amount of heat transferred to the LCD from the projection lamp. This solution is realized through the use of a special wide-band IR filter that prevents IR radiation from reaching the LCD/Micropol assembly. The IR filter used in the preferred embodiment is based on cholesterol liquid crystal reflectors that are made to reflect IR radiation back into the projection lamp. The excess heat is removed by the projection cooling system and is not transmitted to the LCD display.

Abstract: A system and method for converting an analog voltage signal to a digital representation at high speeds, known as an analog to digital converter (A/D converter), is provided. The invention teaches an N-bit A/D converter, made by N superconducting, preferably HTC, transmission lines. The N lines are arranged adjacently and in parallel with each other. On each line 2N-1 JJs are imbedded in series. The JJs form a matrix over the configuration of the N superconducting transmission lines in such a manner that across the lines the JJs give N digit binary numbers, while in the length direction these N digit binary numbers fall in numerical order. A scanning electron beam is made to impinge on this arrangement. The beam is scanned across the lines at a high frequency, while it is deflected by the applied voltage signal along the direction of the lines. The beam generates a voltage step on any one of the N lines on condition of hitting any one of the JJs.
