Abstract: Described are methods, systems and computer readable media for computer data distribution architecture for efficient distribution and synchronization of plotting processing and data.

Abstract: Glare and spurious reflections of external light on the image source of a head up display are eliminated by a circular polarizer in the optical path of the display. The head up display includes a mirror system for projecting a pattern from the image source onto a vehicle windshield where it is reflected to the operator, wherein polarization is effected at the windshield reflection. The circular polarizer includes a linear polarizer and a quarter wave plate arranged to extinguish the external incident light after reflection from the image source. The linear polarizer axis is aligned with the polarization axis at the windshield to optimize the brightness of the display.

Abstract: A method of forming a polymer dispersed liquid crystal (PDLC) film is disclosed which consists of forming a solution of LC dissolved in a monomer, photopolymerizing the solution to form a film having a dispersion of LC bubbles therein, establishing a correlation between the LC bubble size and selected characteristics of the film, selecting a LC bubble size corresponding to desired film characteristics, and controlling the conditions of photopolymerization to achieve said LC bubble size. The LC bubble size is controlled by means of the UV exposure intensity, exposure temperature, exposure wavelength, LC concentration and/or concentration of polymerization initiator. Correlations are noted between LC bubble size and the resulting film's threshold and operating voltages for optical transmission, contrast ratio, absolute transmissivity and electro-optical response times.
