摘要:
The invention relates to a method for identifying the source of shed bioparticles and an apparatus that implements the method. The method involves collecting a sample of bioparticles from the environment, selecting from that sample the bioparticles most effective in identifying their source, and gathering data from those bioparticles to form bioparticle signatures. The bioparticle signatures are then processed into a multi-dimensional vector which is then compared to the multi-dimensional vector derived from a standard using a pattern recognition strategy that identifies the source. The apparatus has a particle collection device to collect the sample, a transfer device that selects information-rich bioparticles and a detector that restricts the movement of the information-rich bioparticles. The restricted movement is then translated into a bioparticle signature.

The present invention relates to a novel method for analyzing nucleic acid sequences based on real-time detection of DNA polymerase-catalyzed incorporation of each of the four nucleotide bases, supplied individually and serially in a microfluidic system, to a reaction cell containing a template system comprising a DNA fragment of unknown sequence and an oligonucleotide primer. Incorporation of a nucleotide base into the template system can be detected by any of a variety of methods including but not limited to fluorescence and chemiluminescence detection. Alternatively, microcalorimetic detection of the heat generated by the incorporation of a nucleotide into the extending template system using thermopile, thermistor and refractive index measurements can be used to detect extension reactions.

The disclosure relates to systems and methods for detecting features on billets of laminated veneer lumber (LVL). In some embodiments, an LVL billet is provided and passed through a scanning assembly. The scanning assembly includes an x-ray generator and an x-ray detector. The x-ray generator generates a beam of x-ray radiation and the x-ray detector measures intensity of the beam of x-ray radiation after is passes through the LVL billet. The measured intensity is then processed to create an image. Images taken according to the disclosure may then be analyzed to detect features on the LVL billet.

A diffuser is provided that includes a glass substrate with a diffusing coating thereon. The diffusing coating may include one or more layers. In certain example embodiments, the diffusing coating comprises inorganic pigments therein for light diffusing purposes, and the inorganic pigments are sized so as to permit a diffuser having a combination of high visible transmission and good diffusion qualities to be realized. In certain example embodiments, the diffusing coating may be of or include a frit with the inorganic pigments therein.

摘要:
A method of making an anti-reflection coating using a sol-gel process, for use in a photovoltaic device or the like. The method may include the following steps in certain example embodiments: forming a polymeric component of silica by mixing glycycloxypropyltrimethoxysilane (or other suitable silane) with one or more of a first solvent, a catalyst, and water; forming a silica sol gel by mixing the polymeric component with a colloidal silica, optionally a second solvent, and at least one organic additive; casting the mixture by spin coating to form a porous silica based layer on a substrate; and curing and/or heat treating the layer. This layer may make up all or only part of an anti-reflection coating.
摘要:
Methods are provided for detecting compression wood, blue stain, or pitch in lumber. A light beam is projected towards the wood sample. Line or area cameras acquire images of light that is reflected from the wood sample. Based on the intensity of the reflected light at one or more locations on the wood sample, compression wood, blue stain, or pitch may be detected.
