The idea is to put the bike light inside the handlebar stem, ensuring it's always there when you need it. The light will be enclosed within an aluminum stem that can fit most bikes. The stem will hold an array of ten LEDs that will send out a combined 500 lumens on high, illuminating an area eight feet wide and six feet at a distance of ten feet. The light can also be dimmed to 300 lumens or switched to a flashing mode, and light intensity and modes will be selected by the two...

The new bike helmet concept will increase biker safety by embedding turn signals into the helmet itself. The helmet system will work via Bluetooth and feature arrow-shaped "turn signals" that will illuminate when the rider triggers a button on the handlebars. A bright forward-facing light and a red rear light will provide added illumination at night.

The practice basketball will be equipped with an array of sensors to provide specific feedback to players to help them perfect their game. Sensors inside the ball will measure aspects of play such as the speed of a dribble or the quality and release of a backspin. The information will be communicated via Bluetooth to a smartphone app that will focus on four different areas: Workout, QuickTraining, Compete and Challenge, which will let players interact with each other around the...

Taking inspiration from nature, I suggest developing a self-healing solar cell that will repair itself with its synthetic vascular system. The self-regenerating solar cell will be designed with a network of channels that will mimic the vascular system of leaves, and will be composed of a water-based gel core, electrodes and light-sensitive, organic dye molecules. The dye molecules will produce electricity when they are "excited" by the sun's rays, but they will eventually degrade...

The skier airbag will be able to detect a crash and inflate to protect the skier from injury. It will be necessary to create an algorithm that will allow the system to differentiate between the normal forces of ski racing, such as a jump or hard turn, and an actual fall. The airbag will only inflate when the data received from at least seven sensors exceeds a designated threshold. Once the signals of a fall have been detected, the 8-liter airbag will inflate using a cold gas...

A waterproof hearing aid could allow the hearing impaired to take part in more activities while still enjoying the added accessibility that hearing aids provide. The rugged hearing aid will be dustproof, shockproof and waterproof at depths up to 3 feet for as long as 30 minutes. The battery compartment will be connected using a silicon sealant, and oxygen will be able to reach the zinc air batteries by moving through a waterproof membrane.
