Abstract: A hyperspectral imaging system is tested in the lab to allow a determination of its response to the emission from a simulated target, of certain wavelengths of radiation which the imaging system will be using during target determination. A broadband IR wavelength generator is used to generate a multiplicity of wavelengths representing the target and an emissions simulator is used to generate wavelengths representing target emission of hot gases. An AOTF is used to delete one or more target wavelengths, and to add one or more emission wavelengths, from and to the transmission path to the imaging system.

Abstract: A multi-channel measurement device for measuring properties of human tissue, may comprise a microcontroller and first and second source/sensor complexes. The first source/sensor complex may include a first housing having a first measurement portion, a first light sensor coupled to the microcontroller and exposed to the first measurement portion, and a first plurality of light sources coupled to the microcontroller and exposed to the first measurement portion. The second source/sensor complex may include a second housing having a second measurement portion, a second light sensor coupled to the microcontroller and exposed to the second measurement portion, and a second plurality of light sources coupled to the microcontroller and exposed to the second measurement portion. The first and second source/sensor complexes are coupled to each other such that the first measurement portion is opposite the second measurement portion and human tissue may be placed between the first and second measurement portions. The microprocessor is configured with instructions stored in non-volatile memory to individually activate each of the light sources of the first and second pluralities of light sources and to record light intensity detected by the first and second light sources while an individual light source is activated. Each combination of an individually activated light source and one of the first and second light sensors provides a distinct measurement channel for measuring the absorption spectra of human blood and tissue.

Abstract: Systems and methods for color selection are provided. A user device displays room types on a display, receives a room type selection indicating a particular room type, displays phrases having words associated with types of feelings, and receives a phrase selection indicating a particular phrase. The user device accesses a lookup table that associates the room types and phrase with paint colors such that each possible combination of room type and phrase is associated with a subset of paint colors. The user device determines the associated subset of paint colors in the lookup table for the combination of the particular room type and the particular phrase and displays the associated subset of paint colors as recommended paint colors for the combination of the particular room type and the particular phrase on the display of the user device.

Abstract: Analyzers and methods for making and using analyzers are described such as a method in which multiple absorption readings of a liquid assay are obtained by a photodetector using multiple light sources having at least three separate and independent wavelength ranges and with each of the absorption readings taken at a separate instant of time. Using at least one processor and calibration information of the liquid assay, an amount of at least two analytes within the liquid assay using the multiple absorption readings is determined.

Abstract: Current techniques for measuring chemical expansion in thin film structures are too slow, too imprecise, or require synchrotrons. In contrast, nanoscale electrochemomechanical spectroscopy (NECS) can be used to make nanoscale measurements at time scales of seconds with simple contact or non-contact sensors. In a NECS measurement, a sample, such as thin-film oxide structure, is subjected to a temporally modulated stimulus, such as a sinusoidally alternating voltage. The stimulus causes the sample to expand, contract, deflect, or otherwise deform. A sensor, such as a contact probe or optical sensor, produces an electrical signal in response to this deformation that is correlated with the temporal modulation of the stimulus. Because the stimulus and deformation are correlated, the temporal modulation of the stimulus can be used to filter the deformation signal produced by the sensor, producing a precise, sensitive measurement of the deformation.

Abstract: A real-time double-beam in situ infrared spectrum system and a method thereof. The system comprises two identical infrared spectrometers and a double-beam infrared reactor cell, wherein the double-beam infrared reactor cell is formed by connecting a sample cell and a reference cell which are identical, the sample cell and the reference cell are at the same level and respectively correspond to a sample spectrometer and a reference spectrometer, the two infrared spectrometers are synchronously controlled by computers, to synchronously collect spectrograms of sample beams and background beams in real time, so as to obtain real information about a species on the catalyst surface changing with the reaction time, and eliminate gas molecule vibration spectrum interference in a real-time state and transmission spectrum interference generated under a heating condition. The present invention makes a characterization result become more accurate and reliable, so that real-time information about an active center of the catalyst surface, an active phase and an intermediate species at different temperatures may be obtained under a changeable gas phase component condition.

Abstract: A method for capturing hyperspectral images using a regular color camera. In the method, the camera takes multiple images of a scene, with the camera oriented differently for each image. For a camera carried by an aircraft or spacecraft, this allows hyperspectral imaging without the cost or weight of a hyperspectral camera.
