Apparatus, System, and Method For Increasing Measurement Accuracy in a Particle Imaging Device Using Light Distribution

Номер: US20120002040A1

Автор: Matthew S. Fisher, Wayne Dennis Roth

Принадлежит: Luminex Corp

An apparatus, system, and method for increasing measurement accuracy in imaging cytometry. The system may include a light detector configured to measure light emitted by a particle in response to a first light source, and processor coupled to the light detector. The processor may be configured create a first image by taking a first measurement of light and create a second image by interpolating the first image, where the second image has higher resolution than the first image. The processor may be configured to determine a difference between pixels of the second image and an expected distribution and discard the first measurement of light if the difference is above a predetermined threshold.

Method for improving paper and board's resistance to the penetration of liquids

Номер: US20120138249A1

Автор: Danny C. Alexander, Patrick Sundholm

Принадлежит: Individual

This invention brings a new aspect in papermaking by spraying hydrophobic chemical directly onto the paper surface in the dryer section of the paper machine, as a two-step process where high solids starch is sprayed on the paper to seal the sheet's surface and thereafter the hydrophobic chemical is sprayed on the paper surface. This invention is a completely new method of hydrophobic sizing, spraying a small amount of a suitable hydrophobic chemical on the moving web in the dryer section, instead of adding hydrophobic chemical in the wet-end of the paper machine, or mixing it in with starch at a size press. This invention reduces the amount of hydrophobic chemical used compared to any of the other processes, it simplifies wet-end chemistry, and it puts the hydrophobic sizing exactly where it is needed, on the paper's surface, which in many cases will be a single side of the paper.

SCALABLE, HIGHLY TRANSPARENT PAPER WITH MICROSIZED FIBER

Номер: US20160010279A1

Автор: Fang Zhiqiang, Hu Liangbing, ZHU Hongli

Принадлежит: UNIVERSITY OF MARYLAND AT COLLEGE PARK

Solar cell substrates require high optical transparency, but also prefer high optical haze to increase the light scattering and consequently the absorption in the active materials. Unfortunately there is a tradeoff between these optical properties, which is exemplified by common transparent paper substrates exhibiting a transparency of about 90% yet a low optical haze (<20%). In this work we introduce a novel transparent paper made of wood fibers that display both ultra-high optical transparency (˜96%) and ultra-high haze (˜60%), thus delivering an optimal substrate design for solar cell devices. Compared to previously demonstrated nanopaper composed of wood-based cellulose nanofibers, our novel transparent paper has better dual performance in transmittance and haze, but also is fabricated at a much lower cost. This high-performance, low-cost transparent paper is a potentially revolutionary material that may influence a new generation of environmentally friendly printed electronics. 1. A transparent paper comprising:an optical transparency of at least 96%; andan optical haze of at least 60%.2. The transparent paper of further comprising;a cell wall;a plurality of wood fibers in the cell wall,wherein the plurality of wood fibers comprise a primary layer and a secondary layer, the primary layer having a thickness of 0.1-0.2 μm and the secondary layer having a thickness of about 1.0-5.5 μm.3.
