Then only paint matching phone app calibrated to ambient light

There are a number of phone apps that are designed to allow consumers to match colors of existing paint or furnishings to paint swatches at the hardware counter.  However, none of the existing tools take into account the differences in lighting between home and the store.  Colors can look quite different under different lighting, resulting in a surprise for painters and product returns to the paint counter.

This new application first developed to allow scientists to measure the reflection on surfaces of water or snow when studying climate change.  It was discovered that with some alterations, the app can also be used to make more accurate paint matches.

To use the app, the user needs to calibrate their digital camera against a gray control card, which could be given out or used at the paint counter.  The consumer would then download the app, take a photo of the paint or furnishings to match, then match with standard/actual paint .

Analyze Samples in the Lab or Field with this New Portable Fluorescence Spectrometer

2010-05 Ring Spec

Custom software and curved reflective surface in this spectrometer reduces size and focuses light so well that inexpensive LEDs replace expensive light sources.

Problems 1.) Important science curricula may not be adequately addressed in high schools because spectroscopy instruments are too expensive to purchase and maintain  2.) Field technicians have to take water and soil samples to a lab for spectroscopy analysis, adding time and complication  3.) Valuable data is not available from remote sensors due to spectrometer power and durability limitations.

Solution: A portable, durable, inexpensive florescence spectrometer

Synthesis of Bacterial Cellulose in Low-cost Culture Medium Using Hot Water Extracted Wood Sugars

20113-10 Bacterial Cellulose Yield

Figure: Bacterial yield in hot water wood extract after 28 days of cultivation at pH (first number) and temp (second number).

Cellulose is well known as one of the most abundant biodegradable materials in nature and has received considerable interest in both academic and industrial fields. Cellulose synthesized by bacteria is of particular interest over plant cellulose for some applications due to its unique structural and mechanical properties and high purity.

Some high value applications for bacterial cellulose include biomedical applications (scaffold for tissue engineering, wound dressing materials, artificial skin), and production of membranes for high tech applications, such as diaphragms for loudspeakers.

Problem: Bacterial cellulose is currently expensive to produce and purchase however, due to the expense of the media.

Solution: Use inexpensive hot water extracted wood sugars for bacterial cellulose production.

The first commercially viable non-toxic fiber board

2013-13 NFC board

UMaine formaldehyde-free particle board sample

This invention provides particle board or fiber board that is 100% non-toxic and 25% stronger than currently available products.  This is accomplished by replacing commonly used formaldehyde based resins with a safe, renewable nanocellulose based binder.

Benefits:

  • Reduction of health problems and related expenses ($9m – $48m per year1) caused by formaldehyde exposure
  • 25% strength increase reduces material and transportation costs
  • Nanocellulose, a renewable resource, replaces binders generally synthesized from non-renewable resources

Reinforcement system increases wall panel strength by 20%

Typical failure at nail site

Typical failure at nail site

 

 

 

 

 

 

 

 

 

When stressed, oriented strand board (OSB) panels tend to fail along the edges and at nail sites, particularly if the panel has gotten wet.  This technology presents a system for waterproofing and reinforcing panel edges.  The reinforced edge improves fastener performance and reduces the edge swell and weakening caused by moisture exposure.  Reinforced edges strengthen the panel by up to 20%.

Real-time nanoparticle particle size monitoring device

Performance quality of many industrial materials depends on consistent distribution of particle sizes within the material.  The ability to quantify other parameters such as surface roughness, surface area, and particle shape is also desirable.  Current methods provide a static, batched measurement of limited utility.  This new method and device provides real-time measurements directly from the manufacturing line flow.

This device has demonstrated performance on paper additive products with aspect ratios ranging from 2 to 8 and short axis diameters between 100 and 500 nm.  Applications are in quality control.

Composite Panels for Blast and Ballistic Protection

panel_installation.jpg

The Modular Ballistic Protection System (MBPS) provides soldiers with enhanced ballistic protection where it never existed before – in their tents where they work, eat, and sleep.  The system consists of composite ballistic panels that are mounted to the inside of the tent frame using an energy-absorbing connection system.  Requiring no tools, the MBPS can be used to up-armor a 20ft x 32ft tent in less than 30 minutes with 4 soldiers.

Method for reducing cross-talk within DNA data

Raw DNA data is filtered with a multi-component analysis that is applied to the difference of the signal intensity on each of the raw DNA data signals to remove cross talk between the signals. The analysis is done before any baseline adjustment of the raw DNA data. Instead, the baseline adjustment occurs after the raw DNA data has been filtered. Additionally, an additional processing step is applied to the data to account for the non-linear nature of cross talk filtering. The additional processing step involves combining the signal with its derivative to account for the correlation of each of the data signals with the other three data signals.

Bridge in a Backpack®

auburnbridgeforweb2.jpg

The Bridge-in-a-Backpack is a lightweight, corrosion resistant system for short to medium span bridge construction using FRP composite arch tubes that act as reinforcement and formwork for cast-in-place concrete. The arches are easily transportable, rapidly deployable and do not require the heavy equipment or large crews needed to handle the weight of traditional construction materials.

To date six Maine bridges have been built using the Bridge-in-a-Backpack technology. Several bridge projects are planned for 2012 throughout New England and beyond.
