Emergency workers risk their lives to keep us safe, and they’re often walking into situations essentially blind. If they run into a problem, they have only primitive ways of warning those coming in behind them. But, with the help of the researchers, the days of flying blind may be coming to a rapid end.
Toyota continues to develop their partner robot initiative. Demographics in Japan make a compelling case for the need to provide solutions to those who need assistance to support independent living. The aim is to contribute to the maintenance and improvement … Continue reading →
I think it is important to increase scientific literacy. One thing that is greatly misunderstood is the process for new scientific explanations being accepted by the scientific community. It is often quite a drawn out process over years (and for … Continue reading →
If you happened by our booth at DesignEast, you may have gotten a personal preview of our new automated parts quoting system. If you didn't get to see it, you will shortly. It's in the final stages of beta. This...
The answer to the question: "is it ever okay to put open vias in BGA pads?" is simply No. It's no, no, no, no, not ever!!! That makes it easy. No technique to worry about. No tolerances. Nothing. Just don't put an exposed via in a BGA pad. The only option is between the pads...
Skin cancer detection breakthrough The researchers found that certain biochemical elements in the DNA of normal pigment-producing skin cells and benign mole cells are absent in melanoma cells. Loss of these methyl groups — known as 5-hmC — in skin … Continue reading →
My last column on alternative energy, A blow to wind energy, evoked more than a few complaints. For an engineering magazine writer a number of people thought that I was light on the numbers. So lets do some numbers. For that we will need a baseline. What is the cost of electrical energy in America these days? The Bureau of Labor Statistics says that the average cost of electricity in the US is 13.5cents per kilowatt hour.
Physics World reports some spectacular advances in turning graphene-based semiconductors into real-world logic chips. Graphene will do some real good for us logic guys because of its carrier mobility. It is over 140 times that of silicon. Plus its heat conductivity is about 10x that of metals like copper and aluminum, and its resistivity is about 2/3rds that of copper at room temperature.
This webcast shows animations of ATP synthase structure and the mechanism for synthesizing ATP. Biology is incredibly cool. Too bad they didn’t have stuff like this when I was in school, instead biology was mainly about memorizing boring lists of … Continue reading →
In our constantly changing world, corporations find themselves continually adapting to new trends and technologies, and often reinventing themselves to remain relevant. In fact, with our changing global business environment, staying the course is not an option if today’s businesses want to remain viable and competitive.
We asked you for your words of wisdom for a brand-new design engineer and boy, did you guys have advice in spades. The responses we received were so good in fact, we’ve decided to open up our November Roundtables to our faithful readers in hopes that you can offer more words of wisdom. Check out the October Roundtable, here.
For all you random number lovers there is some excellent documentation on the www about linear feed back shift registers. LFSRs are a way to produce quasi random numbers without too much effort. Why quasi random? Well one number is excluded (all ones or all zeroes) depending in whether you use the XNOR or XOR function for computing your random number.
