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.

A stable, aqueous barrier coating composition includes: (a) prolamine; (b) cold water insoluble polymer; (c) water; (d) water-soluble co-solvent; and (e) stabilizer. The composition, when applied to a substrate, produces an article having a high surface energy and resistance to oil and grease penetration. A method of producing the article involves applying the composition to a substrate.

US Patent Pending 12/815334
Inventors: Anthony Jabar Jr., Micheal A. Bilodeau, David J. Neivandt, Jonathan Spender
A microscopy system is configured for creating 3D images from individually localized probe molecules. The microscopy system includes a sample stage, an activation light source, a readout light source, a beam splitting device, at least one camera, and a controller. The activation light source activates probes of at least one probe subset of photo-sensitive luminescent probes, and the readout light source causes luminescence light from the activated probes. The beam splitting device splits the luminescence light into at least two paths to create at least two detection planes that correspond to the same or different number of object planes of the sample. The camera detects simultaneously the at least two detection planes, the number of object planes being represented in the camera by the same number of recorded regions of interest. The controller is programmable to combine a signal from the regions of interest into a 3D data.

End users and installers of insulation want a product that is affordable, efficient and safe. Cellulose insulation, generally produced from recycled wood fiber, is affordable and outperforms fiberglass in extreme weather. But cellulose has poor insect resistance and fire retardant qualities without the addition of toxic chemicals. Additionally, the cellulose insulation manufacturing process currently used creates a product prone to settling, which is bad for the homeowner, and dust, which is bad for the installer. ProCell Insulation solves all of these problems, making it a very attractive choice compared to fiberglass and other cellulose insulation brands.
The technology was developed at UMaine in collaboration with the company founders. Company is currently developing manufacturing and distribution networks. Learn more at procellinsulation.com

US Patent Number 8,043,384
PROBLEM: 1.) Important science topics are sometimes not 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 florescence spectrometer that costs 50% less than comparable instruments in most applications due to its novel design and simple components.
PROBLEM: Insulated, ventilated roofs, particularly those covering open floor plans and cathedral ceilings, are difficult and expensive to build.
SOLUTION: These economical prefabricated panels incorporate wood I-joist framing, OSB sheathing, insulation and ventilation into a single product to be used in light-frame construction applications.
TECH ID: 2008-34
DEVELOPMENT PLAN: Undetermined. Has been successfully demonstrated, but on hold given the current downturn in construction.
Environmentally Friendly Adhesive Bonding for Composites, Pollutant Remediation, and Dye Decolorization
PROBLEM: Environmentally friendly methods are needed to bond wood products and other composites without formaldehyde. Organic pollutants and dyes from textile and paper plants in industrial wastestreams need remediation.
SOLUTION: Using the chemically enhanced Fenton system, dyes can be remediated quickly in an environmentally safe manner. Natural lignin from wood residues can be activated to produce an formaldehyde-free adhesive system and organic pollutants in waters or soils can be broken down.
PROBLEM: Composite manufacturers need ways to improve extruded thermoplastics using inexpensive, environmentally friendly ingredients and without slowing process time.
PROBLEM: Commonly available sheet piling used for retaining walls corrodes, increasing maintenance costs and reducing the useful life of the construction. These problems are heightened in a marine environment.
SOLUTION: Our patented wood composite sheet piling system does not corrode, which reduces overall life cycle costs. Additionally it is chemically inert and 100% recyclable.
