Soladey-j3x is a revolutionary ionic toothbrush using titanium semiconductor doesn’t need a toothpaste.

Soladey was invented in Japan by Dr. Yoshinori Nakagawa. The name originates from  the words ‘Solar’ and ‘Dental’. Dr Nakagawa knew that negative ions could be generated from titanium when this metal was exposed to light and water. As with other industrial applications such as water purification and air filtration, ionic power is not a recent discovery. Soladey was first manufactured in the early 1980s and this light activated toothbrush is now used daily by millions of people in Japan primarily, but also now in many other countries.

This can be done and your mouth was claimed to be free from germs. Because, Soladey-J3X utilizing solar panels to transmit electrons to the brush head.

Well, the electrons will react with the acid in the mouth and creates a chemical reaction that can break down plaque and kill bacteria.

The reliability of this instrument was already tested by a company called The Shiken. When it is tested, Soladey-J3X was said able to prove in killing bacteria that hide in the surrounding teeth.

Soladey is effective in order to reduce smokers’ tobacco stains, and there are many testimonials claiming the removal of difficult stains in a matter of weeks with consistent use of the Soladey ionic brush under a good light source.

We are talking about the Wearable Personal Navigation System, and it will blow our mind.

What  you see is a full GPS system built into a set of eyeglasses. It’s not an overlay of a map (which would be awesome, no mistake there), but rather a set of LEDs built into the frames that respond to the position of your head, and then light up in the direction you need to go to reach your destination. For instance, if you’re facing north, and need to go south, an LED will light up in the bottom of the lens, showing you that you need to be going the opposite direction you’re going in. A turn to the east, meanwhile, would show up as an LED in the rightmost side of the frame.

There’s no word on pricing or availability, as they’re still under development, but they’re definitely something that would be great for walking tours. Regular GPS systems are often better designed for car dashes than for walking around, and it would be nice to see a pair that’s as easy as slipping on your glasses.

People will be benefited more from this personal navigation systems, they will make traveling easy and fun for all with the pinpoint directional information.

Maurizio Porfiri, an Assistant Professor of Engineering at the Polytechnic Institute of NYU, is working on a robotic fish designed to lead schools of real fish away from dangers, such as oil spills or turbines.

The tricky part for Porfiri and his team has been discovering exactly what traits fish look for in a leader, so that their robot can successfully mimic these to gain the followers. Experimenting with small schools of fish, Porfiri has been fine tuning his robot to swim with the fast and erratic behaviors that fish would perceive a leader, or mate, to have.

The idea is to one day steer helpless creatures away from dangerous objects like turbines, but there’s still loads of work to do before then — presently, the robot can only swim in two dimensions, and requires a battery to operate. Porfiri’s team at NYU Poly is already researching ways to harvest energy from the water itself, though, and he expects to have his fish powered by waves before long. We will see how this technology will bring us more benefit.

Honda’s unique device lightens the load on the user’s legs and helps maintain a center of gravity via special mechanisms developed by the company.

Honda Motor Co., Ltd. unveiled its second experimental walking assist device that helps support bodyweight to reduce the load on the user’ legs while walking, going up and down stairs, and in a semi-crouching position. Honda will now begin testing the device in real-world conditions to evaluate its effectiveness.

Honda began research of a walking assist device in 1999 with the goal to provide more people with the joy of mobility. Honda developed the knowledge required to develop the walking assist device from its thorough study of human walking represented by the research and development of Honda’s advanced humanoid robot, ASIMO. This research has been conducted by the Fundamental Technology Research Center of Honda R&D Co., Ltd. in Wako, Saitama.
