Bullex, launched at Rensselaer Polytechnic Institute, received Advanced E-Team grants in 2003, 2004 and 2005 to develop the Intelligent Training System (ITS), an innovative fire extinguisher training device. The majority of today's live-fire extinguisher training is done by taking a bucket and filling it with kerosene or diesel, and water. After an instructor lights the fire, a trainee is given an extinguisher and told to put it out. This method is expensive, can be dangerous, and often requires a HAZMAT cleanup.
ITS makes fire extinguisher training more efficient by simulating the extinguishing of a real fire, removing costly extinguishant from the equation. First, flames are generated in a clean-burning, propane-fed pan equipped with digital sensors. If users aim properly and hit the sensors, they can quell the fire without the mess. The sensors then give out a reading on how well a trainee used the extinguisher. The device is cleaner, safer, and easier to use than the traditional training method.
2003 update: Bullex launched successfully in 2003, and now has 60 employees and estimated annual sales of $7.3 million. The company was featured in Fortune Small Business Magazine after making it to the final round of the magazine's national business plan competition, receiving honorable mention. Their customers include the US Navy, Northrop Grumman, Michelin, International Truck, and Trane.
Arteriotomies (the surgical incision of an artery) are required for all catheter-based procedures. Current medical practice requires a large, open incision, an invasive procedure which increases recovery time, hospital and procedure costs, and patient discomfort. To combat these problems, this E-Team developed a device that closes large arteriotomies percutaneously--that is, closes them through the skin in a minimally invasive procedure. The device consists of two components: a vessel-cutting tool, which creates an incision in the vessel of the specific size and shape of the catheter to be used, and a closure mechanism, made of a pre-placed nitinol structure, that provides complete hemostasis to the arteriotomy when the catheter is removed.
This E-Team is concentrating on the problem of the perishability of food and pharmaceutical items. Currently there are two methods of ensuring food/pharmaceutical safety: human predication of expiration, and chemical tags that change color upon product expiration. The E-Team aims to combat the deficiencies of these methods by developing a Time-Temperature Integrator (TTI) tag which, in a 1x2 inch housing, incorporates a temperature measure, a microprocessor, and an RF transceiver. Instead of using the color-change method, these tags record the temperature and time at thirty-second intervals. A calculation of shelf-life is then made based upon a proprietary algorithm that takes into account the current time/temperature and the optimal shelf-life of perishables under those specific conditions. A report of time, temperature and freshness is then sent to a wireless device.

Almost one billion people worldwide do not have access to safe drinking water, most in the developing world. To combat this massive problem, this E-Team created water purification technology in which contaminated water is put into a recycled plastic bottle coated with titanium dioxide and placed in the sun for several hours, killing not only bacteria but other harmful substances such as arsenic and herbicides. The team developed a low-cost manufacturing system for the bottles, field tested the bottles in the network of Peruvian villages they worked with for eight years prior, and researched proper approaches to commercialization of the technology. The team also pursued the possibility of adding a color-changing dye to the bottles to indicate when the destruction of harmful substances in the water has occurred and it is safe to drink.
This E-Team developed an improved walking device that incorporates removable wheels, shock absorbers on each of the four legs, height and width adjustment, a lightweight frame with a wider base at the rear, and detachable accessories such as a seat, basket, cupholder, and more. The team had the full support of Keen Mobility, an NCIIA alumnus and developer of mobility devices for the medical field, allowing the team access to Keen Mobility's resources, relationships with external manufacturing partners, external expert advice, and testing facilities. Moreover, this relationship led the team to adopt Keen Mobility's direct-to-customer distribution model, which should reduce promotional costs significantly.
As part of the Engineers for a Sustainable World program at PSU, this course involved students in creating a hybrid solar/wind power system in Ngegu village in the Division of Rangwe, Kenya, with particular emphasis on water pumps to provide clean water. Currently, residents have to travel a few kilometers to retrieve water that is often polluted, or, worse, has dried up, leading to waterborne disease and high mortality rates. The team also designed a sisal decorticator--a machine that more efficiently harvests the fibers of the sisal plant. Currently these fibers are harvested using a painstakingly slow process that requires entire families to be engaged in harvesting throughout the day.
This project was worked on by four institutions at once: a PSU team of engineering students designed a windmill in conjunction with an engineering team at the University of Nairobi, who initiated the project; a team of business students enrolled in the Introduction to Entrepreneurship course at Bowling Green State University (BGSU) developed a business model for generating funds to support the project; students from all three institutions formed an entrepreneurship team that continued to engage in fundraising and developed a business model; and the Kochia Development Group, an organization of Kenyan businessmen and women who actively seek projects to improve rural Kenya, provided mentoring and feedback to ensure the project is socially and economically feasible.
This E-Team developed an inexpensive, collapsible electronic notebook that can be rolled out for viewing and rolled back into compact form to be carried around. The team's goal is to pair the technology with sub-hundred dollar computers currently under development and get them in the hands of African schoolchildren, 48% of which have no access to textbooks. The team's major innovation is in the area of flexible conductors for the collapsible display: their proprietary conductor technology can exceed strains of 20% without loss of electrical performance, compared to the current industry standard of 1-2%.

The Penn State Agricultural Utility System team, a Sustainable Vision grantee, recently returned from another trip to Kenya where they are developing agricultural tools such as a water well drilling rig and a sisal decorticator.

This E-Team developed a system of products to protect Central California farmworkers from chronic pesticide exposure, which can lead to a wide range of short-term and long-term health effects including cancer, birth defects, and diminished reproductive ability. The team developed two different technologies to combat the problem: a protective suit for the workers and pesticide sensors for their homes. The suit is made from breathable, repellent Tyvek, Teflon and activated charcoal; it consists of overalls with one shoulder strap, an apron over the other shoulder, a hood, a ventilation mask with a carbon filter, gloves, and shoe coverings. The sensors, which incorporate smart dust mote technology to form wireless sensor networks, are designed to detect and record levels of pesticides, providing both an instantaneous alert when pesticides are detected and a long-term record of pesticide exposure, to be used by government agencies like OSHA and EPA in developing case histories of pesticide problems. The team chose the brand name Seguro, which means "safety" in Spanish.

Micro-manufacturing (the production of components with feature sizes smaller than 1mm) is a large and rapidly growing manufacturing sector. Micro-manufacturing machines make parts for both high-volume (iPods, cell phones, etc.) and high-value (surgical devices, military components, etc.) products, but in both cases the machines currently on the market are slow, expensive, large, and difficult to use.
This E-Team, now incorporated as Microlution, has developed a new type of machine, called a Micro/meso-scale machine tool (mMT), that is smaller, less expensive, and more efficient than traditional micro-manufacturing machines. The company is on its feet and growing rapidly, and in 2007 began selling the Microlution 310-S.
