I will, TJ. I have to say, I didn't expect such a lively discussion about this. And people have brought up a lot of points I didn't even think about myself, as they always do (because our readers are a class act!). I definitely am curious to fill in the blanks myself now.
I was going to ask the same questions, which arose since no place in the article did it mention how the power gets to the phone from the charging box. One very big question is how did they avoid the problem of so many different connectors to the phones? I have a stack of 15 old phones using 15 different charging connectors. Of course they are from the era when phone makers wanted to force folks to purchase their vastly overpriced charging cables. That is one area that would have been far better if the government had mandated one single connector type and polarity for each of the three basic charging voltages, and not allowed any exceptions. Now USB charging is sort of like that except for those connectors with the fifth pin and that secret resistor.
What is so very complex about a charging system for a phone? A small generator/ PM alternator and a simple control circuit would do the job and if the gears and bearings were plastic the retail price could be under $10 USD. Of course they would probably have a 1000% markup if they were to be sold elsewhere in the world. Gred does seem to work that way.
The opportunity already exists for an entrepeneur to but a generator (be it hand, solar, pedal) and charge people to use it. The only innovation I see here is to give the cell phone companies a cut by requiring SMS payment. One way of attracting investment for your idea I suppose, but surely better to keep the cash in the local economy? Also, cell phone reception is needed before charging can begin.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
