Our goal is to design a bicycle device that could detect the physical condition and will sent alert if the physical condition fell below a threshold.

Features:
Generate electricity from mechanical source of bicycle to power the detector
Heart rate sensor (and a bio-related sweat sensor) will be inside the bike handle
The pressure sensor will be built in the saddle and both pedals
The accelerometer will be used for collision detection

Function: All sensors are connected to the power system (from mechanical energy) by wires, but they also have a secondary battery. The sensor in bike handle can check the heart rate and (salt %) to determine if the biker is in a safe physical condition. When the sensor notices it after analyzing the data, it can alert the biker to stop or to take a rest. The volume of the alert will be gentle and increase gradually.
If all pressure sensors detect pretty small value, the system will consider that the person is thrown off the bike unless he or she hits the button on the bike. We also implement a delayed emergency response system that gives enough time for user to cancel it. This feature is set to off at the beginning, the biker can choose whether to open it. For example, they can only use this feature when they are going to cycle in the some unsafe places or somewhere with few people. The collision detector will analyze the change of acceleration.

There is a drastic lack of networking infrastructure in unstable or remote areas, where businesses don’t think they can reliably recoup the large initial cost of construction. Our goal is to bring the internet to these areas. We will use a network of extremely affordable (<$20, made possible by IoT technology) solar-powered nodes that communicate via Wi-Fi with one another and personal devices, donated through organizations such as OLPC, creating an intranet. Each node covers an area approximately 600-800ft in every direction with 4MB/s access and 16GB of cached data, saving valuable bandwidth. Internal communication applications will be provided, minimizing expensive and slow global internet connections. Several solutions exist, but all have failed due to costs of over $200/node or the lack of networking capability.

To connect to the internet at large, a more powerful “server” may be added. This server hooks into the network like other nodes, but contains a cellular connection to connect to the global internet. Any device on the network will be able to access the web via the server’s connection, effectively spreading the cost of a single cellular data plan (which is too expensive for individuals in rural areas). The server also contains a continually-updated several-terabyte cache of educational data and programs, such as Wikipedia and Project Gutenberg. This data gives students and educators high-speed access to resources. Working in harmony, these two components foster economic growth and education, while significantly reducing the costs of adding future infrastructure.
