NTU students invent "Block-It-Out" drain cover that stops mosquitoes from breeding

An auto-close drain cover that will block mosquitoes from entering the drain to breed, while allowing a large amount of water to flow through during heavy downpours.

A "near collision" alarm system fitted with an ultrasonic sensor and LED lights that will alert the cyclist via a beeping alarm when a vehicle gets too close.

These are just some of the devices students from the Nanyang Technological University have come up with. As part of the mechanical and aerospace engineering curriculum, second-year students are required to develop a prototype and a business plan to improve certain situations.

One example would be "BikeSense" - a device designed to alert cyclists and motorists when they are of too close a distance to each other. It won first prize in a Safety & Security category of the 15th Engineering Innovation and Design Open House and Competition on May 18. The 580 submissions in five categories were judged by industry professions, alumni and faculty members.
