Residential fires kill and injure thousands of Americans and cause billions of dollars in property damage each year. More than 428,000 home fires occurred in 1996, which resulted in a residential fire every 74 seconds, according to the National Fire Protection Association (NFPA). By the mid 1980s, laws that required alarms in all new and existing residences existed in 38 states and thousands of municipalities. Systems wired throughout the house are expensive to install and provide only a general alert, while standard smoke alarms are not interconnected. This E-Team’s Location Specific Alarm Relay (LSAR) system is designed to be installed in individual rooms, but has the ability to transmit data and can relate the location of smoke in the event of a fire. For example, the existence of smoke in the basement will be relayed to the second floor bedroom through a combined horn and voice alarm
Breast cancer is the second leading cause of death among women. Current mammography screening techniques, which use polychromatic X-ray sources and compression techniques to obtain images of the breast, have a number of shortcomings.
This E-Team developed a compressionless monochromatic 3D mammography screening system to improve on the old model. The Patient Rotation System is a model table on which a patient can be rotated to allow the system to produce accurate three-dimensional images. The team made the table movable, able to rotate with the breast as a center point in order to easily screen the breast and chest wall, and improved the comfort of the experience for mammography patients.
Dairy farmers, animal processing facilities, and wastewater treatment plants use biogas generated from the anaerobic digestion of organic matter to stabilize their waste streams, facilitating processing for disposal or its conversion into usable by-products. NCIIA funding supports this E-Team in completing a technical feasibility study for a modular reactor that pressurizes and purifies biogas produced from anaerobic digestion of biomass using a closed-loop system. This will be the first step toward the commercialization of biogas-producing technology for use by commercial, industrial, and consumer clients who could benefit greatly from a reliable source of clean, renewable energy.
The US water supply and wastewater treatment is a $110 billion industry, of which $32.1 billion (30%) was spent in 2002 on capital improvements at municipal wastewater treatment facilities. In the next six years, municipalities are expected to spend an additional $100 billion to meet state and federal environmental standards. The team’s goal is to determine a practical system design and identify appropriate markets for commercialization, developing a thorough understanding of the economic value proposition for this technology
This E-Team developed a single-switch automated page-turner designed to aid people lacking manual strength and dexterity in reading a hardcover book. The device is user-friendly, single-switch activated, affordable, reversible, lightweight, portable and easy to load, utilizing a washable and renewable commercially available adhesive.

This E-Team developed a prototype device for removing arsenic from Bangladesh's drinking water. The device uses chemically treated bottom ash (residue left over from coal combustion) as the medium for removing arsenic. The invention is based on coating the surfaces of bottom ash particles with ferric hydroxide, and using this treated ash to react with, remove, and immobilize arsenic in water supplies. Lab results demonstrated that 5 gm of treated bottom ash can reduce arsenic concentration in 2.4 liters of water from 2400 ppb to 10 ppb.
The E-Team believes the final product’s pricing model will be proportional to table salt, costing <.30/kg per person per year. The business costs are also comparable to table salt.
The team consisted of four lab-based professionals in chemical engineering and physics.
Wheelchair basketball is among the five highest risk sports for the disabled. Injuries resulting from collisions are frequent during wheelchair basketball because the athletes must not only control the ball and the game, but also themselves and their chairs.
The Balance Sport Wheelchair E-Team has designed a less cumbersome, more responsive, and safer wheelchair that employs a simple leaning/braking system to help the athlete control herself. The seat of the wheelchair sits atop a centralized column that passes through a universal join mechanism; the column extends down where it's attached to a braking system on the chair’s two large wheels. When the player leans left, the chair turns left; when they players leans right, the chair turns right; when the player leans back, the chair stops.
The E-Team consists of four students: three undergraduates majoring in industrial design, and one member of the University of Illinois wheelchair basketball team
This E-Team looks to make the UC Berkley shuttle system safer and more convenient by developing a shuttle tracking service. The service provides the location of Berkeley shuttles to students and other riders through a central server connected to the internet. Each shuttle transmits its location data via a built-in GPS device to internet access points situated throughout the shuttle routes. Users can access the location data with their cell phones, through the web, or on public display boards placed near campus buildings.
The team consists of three students specializing in electrical engineering and computer science, business administration, and bioengineering. One professor of engineering and five industry advisors aid the students in areas of design, marketing, and safety

80% of a product’s cost is decided early on by design, purchasing and manufacturing decisions. However, little information on cost is typically available until the design is completed and the company begins manufacturing. This lack of information about cost during product development can have a great impact on overall expense, particularly if design changes are made later in the product cycle. The Enterprise Cost Solution E-Team developed a technique, called Feature-Based Costing (FBC), that quickly and accurately estimates production and tooling costs early in the design process using readily available information. The device determines information automatically from the engineer’s solid model and does not require user input. FBC software estimates total part costs, including material, overhead, processing, and tooling costs.
Needle-based drug delivery is often painful, has limited accuracy, and typically requires a visit to a doctor’s office. Some therapeutics are totally inaccessible to individuals because they can't safely and reliably deliver the drugs themselves. To address these problems this E-Team has developed a hand-held microjet drug delivery system to replace the use of hypodermic needles in treating arthritis patients. The piezoelectric actuation device accurately delivers the correct dosage with minimum pain.
