ISE 2017, the largest audio-visual and systems integration show, was held recently in Netherlands.
Casio, a major player in the industry, showcased its new projectors made with the latest technologies.
At the event, the 4K technology integrated projectors remained the showstopper.
Danyang Oram, Casio Assistant Planning Manager of Projector Division UK, "4K is a resolution that is four times of full HD resolution which gives you a much better image than a full HD, and be able to present a more detailed videos also crispier images on the edge. And also if you look at the presentation in the still images that are not moving, then a full HD projector comparing to a 4K is much different."
These projectors are more environmentally friendly compared to conventional mercury lamp projectors.
A Netherlands teacher said, "I am now very interested in projectors that will work with LED lights so we will substantially reduce our energy consumption. Then we won't be needing mercury for the bulbs we are now using any longer. And I hope therefore, that we, with that, can take another step to become indeed the greenest school in the Netherlands."
The high-resolution and environmental friendly projectors can make the users' life more exciting and convenient.
Sadatoshi Nakamura, General Manager of Projector Development, Casio, said, "We have succeeded in creating projectors using a new light source, the semiconductor light source. Particularly, we developed the hybrid semiconductor light source from a LED laser. By doing so, we have made this table-top style projector with this kind of light. This one is using interactive software, therefore it is operable by touching the 'table-top' screen. When you touch the screen, you can enlarge and reduce sizes, flip pages, or switch displays. With products like this, we are considering how it will be used by the consumers and how we can help them."
In Japan, many infrastructures like the bridges are getting old.
NEC has been conducting experiments to enhance the efficiency of the maintenance of bridges in the country.
Akihiko Iketani, Senior Manager, Central Research Laboratories, NEC Corporation, "In Japan, we have a serious aging problem with the social infrastructures. The majority of the infrastructure is turning 50 years old which is the end of their lifecycle. Because of that, we are spending $10billion per year to maintain those aging infrastructures."
NEC's maintenance staff has been examining old bridges to make repairs by using efficient system.
Iketani added, "The key idea is 'Preventive Maintenance'. Instead of applying a heavy, large scale of repair, we apply small repair at the early stages. Think about curing a cancer. The earlier you detect the cancer cells, the higher the survival rate and the lower the medical fee."
The engineering staff identifies the damage and diagnoses it with adequate technique.
The process of repairing the road is to install sensors on it to measure the vibrations of the cars passing through above at all times.
The movement of the concrete structure will be displayed via visual data.
While the road appears to be a neat waveform when it is normal, when deterioration progresses, it becomes irregular and the shape changes randomly.
NEC is targeting to implement this technology by 2018.
Iketani said, "Any country can have this kind of same aging infrastructure problems. We believe that technologies and solutions that we have proved in Japan can be applied to other countries as well. NEC has the technology. NEC has the solution. We are ready to solve that problem."
In Tokyo, where the residents consume 70 per cent of the electricity in all of Japan, efforts are being made to create a society that uses hydrogen, the next generation's energy with no CO2 or exhaust gas emissions.
To electrolysis water, hydrogen will be generated from the negative pole and oxygen will be generated from the positive pole.
When hydrogen enters the fuel cell, one side of the electrode splits into hydrogen atom and electric. The hydrogen atom goes through the electrolyte.
Electronics develop into electricity and move to the next electrode. After mixing with the oxygen in the air, it comes out as water.
Fuel cell can be charged with hydrogen and it can move automobiles.
During calamities, using the electricity from the hydrogen fuel cell, people at hospitals or shelters can evacuate.
Kiyofume Tobe of the Tokyo Environmental Public Service Corporation said, "In order to prevent global warming, a low carbon society must be achieved. It is very effective considering realizing a hydrogen energy society as a trump card of the low carbon society."
Hydrogen will be spread out into the world and be connected to effectively maintain the environment.
