I have learned from experience that good safety deivces are hard to find. My wife and I do not believe in the learn by experience method of child rearing. We consider it a form of child endangerment. That type of child learning could result in burning our house to the ground, along with injury or death to us.
We have a granddaughter who just turned two living with us since her birth. I have had to be very inovative about safety issuses. First, we have a wall heater in our living room. I had to make a barrier out of PVC pipe to keep her away from the heater.
She got tall enough to reach the pots on our electric cooktop. After researching the internet for stove safety panels I realized that there were no affordable, effective items on the market. I built one using some aluminum strips, right angle brackets, 1/4-20 screws, wing nuts, and a 1/2" thick plastic sheet. The wing nuts, which face the cooktop, are easy for an adult to remove in order to clean the top.
The last job was when she discovered the start button on the electronic control panel for the dishwasher. I made a removable cover out of some aluminum and roof flashing that fits over the top of the door. It covers the entire control panel and has a hole drilled in it to see the green light that goes on when the cylce is done.
I also had to make my own safety catches for the kitchen cabinets and drawers. We tried commercial plastic ones that broke and could be opened by a kid. What I made doesn't look great, but they do the job.
It seems like the only answer to some safety ptoblems is the do it yourself method. This might not help most of the general public, but it should be useful for many with an engineering background.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
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.
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.
