Abstract:
Encoded spatio-spectral information processing is performed using a system having a radiation source, wavelength dispersion device and two-dimensional switching array, such as digital micro-mirror array (DMA). In one aspect, spectral components from a sample are dispersed in space and modulated separately by the switching array, each element of which may operate according to a predetermined encoding pattern. The encoded spectral components can then be detected and analyzed. In a different aspect, the switching array can be used to provide a controllable radiation source for illuminating a sample with radiation patterns that have predetermined characteristics and separately encoded components. Various applications are disclosed.

A device of measuring calorie of an object includes an object holding unit (1) including a table (2) on which an inspection-target object (M) is placed; a light source unit (20) that supplies light in near-infrared regions to irradiate the inspection-target object (M) placed on the turning table (2); a light reception unit (30) that receives light reflected from or transmitted though the object (M); and a control unit (40) that calculates the calorie of the object (M) in accordance with the absorbances of the light received by the light reception unit (30). In the control unit (40), the calorie of object (M) is calculated in accordance with a regression expression and the absorbances of the light received by the light reception unit (30). In this case, the regression expression is preliminarily calculated in the manner that near-infrared rays are irradiated on a calorie known sample object (M), and multiple-regression analyses are performed on second derivative spectra at the absorbances of light reflected from or transmitted though the sample object (M).

Abstract:
Propellant free foamable aqueous dentifrice system which is capable of being delivered as a foam to a toothbrush and which is stable on the brush and when placed in the mouth and used for tooth cleaning, continues to generate more foam. The system is liquid and as such can not be used without being foamed because it is so thin that it falls beneath the bristles of the toothbrush.
Abstract:
A spectroscopy system is provided which is optimized for operation in the VUV region and capable of performing well in the DUV-NIR region. Additionally, the system incorporates an optical module which presents selectable sources and detectors optimized for use in the VUV and DUV-NIR. As well, the optical module provides common delivery and collection optics to enable measurements in both spectral regions to be collected using similar spot properties. The module also provides a means of quickly referencing measured data so as to ensure that highly repeatable results are achieved. The module further provides a controlled environment between the VUV source, sample chamber and VUV detector which acts to limit in a repeatable manner the absorption of VUV photons. The use of broad band data sets which encompass VUV wavelengths, in addition to the DUV-NIR wavelengths enables a greater variety of materials to be meaningfully characterized. Array based detection instrumentation may be exploited to permit the simultaneous collection of larger wavelength regions.

This invention provides methods for treating a variety of disorders using localized electromagnetic radiation directed at excitable tissues, including nerves, muscles and blood vessels. By controlling the wavelength, the wavelength bandpass, pulse duration, intensity, pulse frequency, and/or variations of those characteristics over time, and by selecting sites of exposure to electromagnetic radiation, improvements in the function of different tissues and organs can be provided. By monitoring physiological variables such as muscle tone and activity, temperature gradients, surface electromyography, blood flow and others, the practitioner can optimize a therapeutic regimen suited for the individual patient.
Abstract:
An image data processor comprising an image signal receiver, a histogram generator, a gain calculator, an amplifier, and a signal feeder, is provided. The image signal receiver receives an autofluorescence image signal. The autofluorescence image signal is generated by an imaging device when the imaging device captures an autofluorescence image. The histogram generator generates a histogram of luminance in the autofluorescence image based on the autofluorescence image signal. The gain calculator calculates a gain based on the histogram and a predetermined luminance value. The amplifier amplifies the autofluorescence image signal by the gain. And then the amplifier generates an amplified autofluorescence image signal. The signal feeder outputs the amplified autofluorescence image signal to a monitor. The monitor displays an amplified autofluorescence image.
