Another cool innovation from NCIIA's Sustainable Vision program - the Mashavu healthcare system, created by a team at Penn State. Think Tanzania, where there's one doctor for every 50,000 people, meaning that many never see a doctor in their lives. Think technology: Biomedical diagnostic tools and a data entry system, operated by trained local villagers. The diagnostic system is connected to a network of doctors in the US, who can review the data and prescribe situation-appropriate medical treatment. In this video, team leader Khanjan Mehta describes the technology (clips provided by Cornell University's eClips program).
This E-Team developed the Shelton Wing in Ground Effect (SWIG) vehicle, a type of airplane/boat that skims the surface of water. Flying near the ground reduces drag and increases lift, allowing Wing In Ground (WIG) vehicles to move at high speeds while consuming little fuel. However, traditional WIG vehicles have significant stability and control problems, causing frequent wrecks and preventing them from achieving commercial success. Computerized flight controls have solved the stability problems of large WIG vehicles, but are too costly to be practical for small WIG vehicles. Three-axis airplane-like controls solve the stability problem as well, but require special pilot training, creating a barrier to wide commercialization. To solve these problems, this E-Team innovated the WIG, adding forward wheels to the wings (skis for water operation) that stay in light contact with the surface. The wheels balance the pitching of the vehicle, creating a reliably safe, fast, and fuel-efficient transport.
The E-Team consisted of two senior finance majors, a senior astrophysics major, a senior advertising/public relations major, and a senior aerospace engineering student with pilot experience. Advisors to the team included three professors of aerospace engineering, a patent attorney, and a financial consultant.
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.
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.
While energy conservation is becoming increasingly important in today's world, there is no convenient, inexpensive, easy-to-use energy monitoring and control product for residential and small business markets. To fill the void, this E-Team developed i-conserve, an energy conservation solution for small businesses and homes that consists of a wireless sensor network of modules (outlets), a base station that acts as a hub for the information in the network, and software that modifies energy settings in order to maximize efficiency and also provides the user with recommendations on how to improve efficiency. The base station is a USB ZigBee dongle (an electronic device that must be attached to a computer in order for it to use protected software) that allows a computer to communicate with the ZigBee mesh network. ZigBee itself is a new advancement in wireless sensor network technology that represents a reduction in cost and power consumption.
The team received a small amount of funding as part of the 2002 "E-SHIP Venture Fund and Competitions" Course and Program grant to PSU. The team has already begun prototyping, attended a ZigBee conference to begin networking, and filed two provisional patents.
The Buzby Networks team is creating a wireless network solution for the healthcare industry, particularly nursing homes. The team's system will allow for the wireless tracking of patients, equipment, and personnel.
The need for Buzby's network comes primarily from the tendency of some nursing home patients to wander off, escape, and put themselves and others in danger. Buzby Networks believes its wireless technology will provide peace of mind to families and staff.
Mashavu enables medical professionals around the world to connect with patients in the developing world using modern technology and communications infrastructure. The goal is to bring basic medical care to people in developing countries, using laptops, cell phones, innovative software and simple medical devices.
Trained operators at Mashavu stations in developing communities collect essential medical information including weight, body temperature, lung capacity, blood pressure, photographs, stethoscope rhythms, and basic hygiene and nutrition information for each patient on a regular basis. Web servers aggregate this information from various Mashavu stations over a cell-phone link and provide it on a web-based portal. Medical professionals can view the patient’s information and respond to the patient and the nearest doctor(s) with their recommendations. Validation efforts have shown that numerous entities are willing to purchase Mashavu stations. They can charge customers a small fee, thereby making Mashavu economically sustainable and creating an additional revenue stream.
