Abstract: A sensor for use in an optical temperature detector system having a birefringent element made of a single crystal metal oxide plate. A broad band light spectrum is transmitted through a first linear polarizing element to create a linearly polarized wave. The linearly polarized wave on passing through the single crystal metal oxide plate decomposes into first and second orthogonally polarized waves. Propagation of the linearly polarized wave through the birefringent single crystal metal oxide plate introduces a temprature dependent phase shift between the two waves. Thereafter, a second linear polarizer combines the first and second orthogonally polarized waves to create a modulated light spectrum having a fringe pattern, the fringe pattern being a function of the current temperature experienced by said birefringent element. A fiber optic cable connected to the second linear polarizing element carries the modulated light spectrum to an opto-electronic interface where the fringe pattern is extracted and a computer compatible signal is generated for a CPU to accurately indicate current environmental temperature conditions up to 1000 °C experienced by the single crystal plate crystal in the birefringent element.

Abstract: A process for photostabilizing an anatase titanium dioxide-delustered polymer textile component which includes dispersing a plurality of anatase titanium dioxide particles in water, introducing a silica source material, such as sodium silicate, to the resultant dispersion to form a suspension, lowering the pH of the suspension to below about 6.0, preferably below about 3.5, to precipitate silica from the silica source material and form an amorphous silica coating on the anatase titanium dioxide particles, blending the silica-coated anatase titanium dioxide particles with a polymer resin and extruding the resultant blend to form a textile component; and a carpet produced from the textile components. In a preferred embodiment, alumina also is deposited onto the silica-coated anatase titanium dioxide particles. This process is particularly effective for polymer textile components subjected to a low pH stain resist aftertreatment.

Abstract: Polymer compositions having a styrene-derived backbone chain and having pendant side chains containing a nitrone functional group undergo changes in refractive index upon exposure to actinic radiation. Waveguides are 'written' in films containing such polymers by exposing predetermined areas to sufficient radiation to change the refractive index.

Abstract: A system for producing ultra-high peak power pulses employs a plurality of solid state amplifying materials (13, 14, 15, 16), such as Nd:glass, alexandrite, and Ti:sapphire, to achieve stretching of a pulse (12) prior to amplification by a factor of approximately between 100 and 10,000. The time-stretched pulse is amplified by many orders of magnitude, illustratively 109. After time-stretching and amplification, the pulse is then compressed to its original duration (11). Pumping of the multiple solid-state elements (13, 14, 15, 16) is performed simultaneously using an alexandrite laser which is tunable between approximately 700 and 800 nm. The pumping energy has a pulse duration which is less than the fluorescence lifetime of the excited solid-state media.

Abstract: Disclosed herein is a method of matching engine torques in a power management system having a digital engine control (18L, 18R) for each of multiple turbine engines (12L, 12R). Input data is selected from one source such that each digital engine control (18L, 18R) utilizes the same set of input data to generate torque commands. As a result, engine torques can be matched to within one percent.

Abstract: A process for analyzing a spectral signal generated by a birefringent element and transmitted to an array. An output spectral signal emanating from the array is converted from an analog to a digital signal to establish a reference waveform which has a dominant frequency after the birefringent element is exposed to a known temperature. Thereafter, a current waveform is generated from the output spectral signal emanating from the array. A phase and frequency relationship is obtained by cross correlating the current waveform and the reference waveform. The dominant frequency for the phase and frequency relationship is obtained by Fast Fourier Transformation. Thereafter, the dominant frequency for the phase and frequency relationship of the current waveform is compared with the dominant frequency for the reference waveform to determine a temperature range. The temperature range and phase and dominant frequency for the current waveform are matched with a reference schedule stored in the memory of a digital signal processor to predict the current temperature experienced by the birefringent element. This predicted temperature is displayed on a screen to inform an operator of the current operational conditions experienced by the birefringent element.
