A filter comprises a support substrate. A film is disposed on the support substrate, the film comprising a polymer matrix material and a filler. The filler has a particle size distribution configured to filter a desired range of wavelengths of light, the particle size distribution having been achieved by extrusion. An extrudable composition is also disclosed. The extrudable composition comprises a polymer matrix material and a filler. The filler has an average particle size ranging from about 1 nm to about 700 nm and a concentration ranging from 0.001 weight % to 0.3 weight %, relative to the total weight of the extrudable composition.

Extrudable compositions comprising fillers and devices made from the compositions

Disclosed are curved electrochromic devices comprising an electrochromic apparatus disposed between first and second curved layers of transparent material, and the first and second curved layers have exterior and inner surfaces, wherein the inner surfaces face the electrochromic apparatus. Also disclosed are processes for manufacturing the disclosed bubble visors.

Electrochromic device

A specular variable angle absolute reflectometer includes a light source and a mirror system in a light path of the light source. The mirror system is configured to reflect a light beam from the light source towards a sample that is optically reflective. The device also includes an elliptical roof mirror disposed in the light path after the sample having an ellipsoidal reflector surface configured to reflect the light beam back towards the sample. The device also includes a mechanism connected to the elliptical roof mirror. The mechanism is configured to rotate the elliptical roof mirror about an axis of the sample. The device also includes a detector in the light path after the elliptical roof mirror such that the detector receives light that has been reflected from the elliptical roof mirror, thence back to the sample, thence back to the mirror system, and thence to the detector.

Specular variable angle absolute reflectance method and reflectometer

A method of controlling a particle size distribution of a filler in an extrudable composition comprises introducing an extrudable composition comprising a polymer matrix material and a filler into an extruder, the filler having a first average particle size that is larger than a target average particle size. The extrudable composition is extruded one or more times using the extruder to reduce the size of the filler from the first average particle size to a reduced average particle size, the reduced average particle size being within 10% of the target average particle size.

A method involves determining multiple temperatures of an object from spectral data collected from the object. The spectral data covers a plurality of wavelengths. The method comprises using a computer to (a) assign an initial value for residual radiation; (b) identify a black body profile that best fits the spectral data over the plurality of wavelengths; (c) remove radiation corresponding to the identified profile from the residual radiation; and (d) return to (b) until the residual radiation reaches a termination criterion.

Non-contact measurement of multi-temperature profile of an object

Systems and methods are provided for measuring spectral hemispherical reflectance. One embodiment is a system that includes a laser that emits a beam of light, and an optical chopper disposed between the laser and a sample. The chopper blocks the beam while the chopper is at a first angle of rotation, redirects the beam along a reference path while the chopper is at a second angle of rotation, and permits the beam to follow a sample path through the chopper and strike the sample while the chopper is at a third angle of rotation. The system also includes a hollow sphere that defines a slot through which the sample path and reference path enter the sphere. The hollow sphere includes a spectral hemispherical reflectance detector, a mount that receives the sample at the sphere, and an actuator that rotates the sphere about an axis that intersects the sample.

Apparatus for measuring spectral hemispherical reflectance of samples at grazing angles

A method of thermographic inspection includes absorbing, at an applique applied to a test area of an article, light from a testing light source. The method further includes emitting, by the applique, thermal radiation directed to a capture device, the thermal radiation corresponding to at least a portion of the light absorbed by the applique.

Applique and method for thermographic inspection

An apparatus for determining a temperature of an object without contacting the object. An etalon filter may be used to receive spectral radiation of the object over a plurality of wavelengths and to generate a spectral output signal. A linear array detector may be used that is responsive to the spectral output signal from the etalon filter and adapted to generate an output indicative of the spectral radiation at each of one of the plurality of wavelengths. An actuator may be used that controls movement of one element of the etalon filter to assist in generating the output. A processor may be used which is responsive to the output of the linear array detector and which analyzes a known characteristic of a black body at a plurality of test temperatures, against the output of the linear array detector, to determine a specific temperature of the object.

Emissivity independent non-contact high temperature measurement system and method

A system and method for determining the temperature of an object without physically contacting the object. The method involves reading a spectral radiation of the object over a plurality of wavelengths to obtain a set of radiation data related to a temperature of the object. A known characteristic of a black body is determined at a plurality of predetermined, different test temperatures. The spectral data and the characteristic of the black body at the various test temperatures are used to calculate a temperature of the object.
