The Google+ Project, Is it the new Facebook rival??

One of the most sophisticated project newly presented by Google in the social media to defeat their rival in this kind of industry, Facebook, is a Google + project. Google has some project that is presented but failed to meet the consumer requirement, The Google Buzz is definitely can’t find it’s way in delivering the message of social media.

Google has some achievement in mobile devices too, Android, that they will implement this new project to it. What are they plus?? What makes them different from Facebook, Friendster, and Twitter?? Or maybe they are only just another improvement like Facebook from Friendster??

Self-Driven Google Car

Google once again amazed me with the video published in youtube where a modified Toyota Prius Car automatically. They are making another innovation with the implementation of software and hardware connected to a car that can drive with some sensors. They have been developing technology for cars that can drive themselves. Our automated cars, manned by trained operators, just drove from our Mountain View campus to our Santa Monica office and on to Hollywood Boulevard. They’ve driven down Lombard Street, crossed the Golden Gate bridge, navigated the Pacific Coast Highway, and even made it all the way around Lake Tahoe.

The automated cars use video cameras, radar sensors and a laser range finder to “see” other traffic, as well as detailed maps (which we collect using manually driven vehicles) to navigate the road ahead. This is all made possible by Google’s data centers, which can process the enormous amounts of information gathered by our cars when mapping their terrain.

To develop this technology, we gathered some of the very best engineers from the DARPA Challenges, a series of autonomous vehicle races organized by the U.S. Government. Chris Urmson was the technical team leader of the CMU team that won the 2007 Urban Challenge. Mike Montemerlo was the software lead for the Stanford team that won the 2005 Grand Challenge. Also on the team is Anthony Levandowski, who built the world’s first autonomous motorcycle that participated in a DARPA Grand Challenge, and who also built a modified Prius that delivered pizza without a person inside. The work of these and other engineers on the team is on display in the National Museum of American History.

I am hoping with the testing of these kind of technology will provide us a better future in reducing a car accident, pollution, fuel consumption, etc. I hope some new ‘smart car’ will help human to a better future. In mass production will reduce the cost of engineering, will it be publicly provided to us? We’ll se soon.

Citizen CA0030-52E Eco Drive

Do you know any of the automatic, kinetic, solar powered, and eco-drive technology on watches? I know some watches used these kinds of technology. Some model have their own technology. Rolex uses an Automatic, Seiko uses Kinetic technology, Casio Protrek edition uses tough solar, and Eco-Drive technology is used by Citizen. But there are other model that use the same technology like automatic be used in Seiko 5 too.

In my recent article, I would like to write about an Eco-Drive Technology that is used by Citizen. Eco-Drive is the series name of a line of mainly light powered watches manufactured by the Citizen Watch Co., Ltd. The first Eco-Drive watches were sold in 1995. In other technology, Tough Solar is the name given by Casio to the solar powered battery charging system used in its G-Shock, ProTrek, Pathfinder and other lines of watches. A self-contained, environmentally-friendly solar cell provides a supply of energy to the watch. Spare solar energy is saved in a battery. Normally, the solar cell and rechargeable battery should be able to last as long as the watch.

Light as power source

Most Eco-Drive type watches are equipped with a special titanium lithium ion secondary battery that is charged by an amorphous silicon solar cell located behind the dial.[2] The titanium lithium-ion composition precludes it from being affected from the regular charge/discharge cycle of other types of rechargeable batteries. Light passes through the covering crystal and dial before it reaches the solar cell.[3]

Depending on the electronic movement model, a fully charged secondary power cell could run with no further charging anywhere from 30 days to 3,175 days (8.7 years), though most Eco-Drive men’s watch models offer a six-month power reserve.[4] If kept in the dark for too long, some movement models engage a hibernate mode, where the hands of the watch stop running but the internal quartz movement still keeps track of time. If an ample supply of light is given, the hands move to the proper positions and resume regular timekeeping. Continue reading

The Implementation of the Not and And gates using only the Nand gate.

The book’s said that The NAnd Function has an interesting theoretical property : Each one of the operations And, Or, and Not can be constructed from it, and it alone. Since every Boolean function can be constructed from And, Or, and Not operations using the canonical representation method, it follows that every Boolean function can be constructed from Nand operations alone.
Some of the logic gates presented here are typically referred to as ‘‘elementary’’ or ‘‘basic.’’ At the same time, every one of them can be composed from Nand gates alone. Therefore, they need not be viewed as primitive. Due to this property, NAND and NOR gates are sometimes called “universal gates”. Continue reading
