How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.

The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “it’s kind of like having a dentist actually watch your brushing on a day-to-day basis, says Thomas Serval, the French inventor.

The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun,” Serval says.

Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

The company says the Kolibree will go on sale this summer, for $99 to $199, depending on features. The U.S. is the first target market.

Serval says that one day, it’ ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

Speaking a foreign language is a high demand skill nowadays. Foreign language skills can help you get jobs. It even matters if you’re a social worker—the ability to communicate with customers in their own language is a huge advantage.

Learning a foreign language takes years of hard work. Luckily, two famous Japanese inventors took language translation to the next level and created an instant translator called MUAMA Enence. It can easily translate real-time speech into over 40 languages using only a few finger-taps. Thus, you don’t need to learn another language to be able to communicate in it. Difficulties caused by language barriers will soon be a thing of the past!

MUAMA Enence can transform you into an able-communication instantly. With its lightweight design and small size, MUAMA Enence is easy to carry in any pocket and is right there when needed. MUAMA Enence is inexpensive. An experienced professional translator or interpreter can be costly, and you need to pay more than once. MUAMA Enence requires just a one-off payment for a huge selection of languages. Its built-in advanced technology can support a 2-way language translation. Moreover, a text translation is also available.

Though MUAMA Enence was created mainly for travelers, it started gaining massive popularity among people of different occupations. All of a sudden, it became a must-have device! What surprised us is that more and more social workers and volunteers are choosing MUAMA Enence to make their work easier. We asked people who have used MUAMA Enence to explain how it works for them. The results showed that people have increased their job quality after using the Translator.

Language barriers should no longer be your concern anymore, and the answer is definitely YES! Now it’s the best time to do it, because MUAMA Enence may run out of stock soon due to its high popularity worldwide.

Researchers have proposed a novel method for counting and tracking vehicles on public roads, a development that could improve current traffic systems and help travelers get to their destinations faster.

Using the cameras already installed on campus buses at the Ohio State University, researchers proved that they could automatically and accurately measure counts of vehicles on urban roadways, detect objects in the road and distinguish parked vehicles from those that are moving.

In previous studies, Ohio State researchers found that using these mobile cameras provides much better spatial and temporal (时间的) coverage than relying on often temporarily placed sensors that don’t provide a view of many streets and roads in a city.

“If we collect and process more high-resolution (高清) spatial information about what’s happening on the roads, then planners could better understand changes in demand, effectively improving efficiency in the broader transportation system,” said Keith Redmill, lead author of the study.

“If we can measure traffic in a way that is as good or better than what is conventionally done with fixed sensors, then we will have created something incredibly useful extremely cheaply,” he said. “Our goal is to start building a system that could do this without much manual intervention because if you want to collect this information over lots of potential vehicles and lots of time, it’s worth fully automating that process.”

While still a long way from total implementation (实施), the study suggests the system’s results bear promise for the future of intelligent traffic surveillance. Transportation planners, engineers and operators make vital decisions about the future of our roadways, so when designing transportation systems to work over the next 30 to 50 years, it’s necessary that we give them data that allows them to improve the efficiency of the system and the level of service provided to travelers.
