Lately, there has been a lot of buzz about 3D projection mapping. I first heard about it from an electronic music enthusiast who plans to acquire projection mapping software and add this extreme visual component to his live shows. But many people were introduced to projection mapping from the coverage of the Winter Olympics in Sochi this year or from the viral video of projection mapping shown below, a pre-game show on the court floor at a Cleveland Cavaliers game. Prepare to be astonished.

If you work in hazardous locations and conditions, you would understand the need to promote safety and ensure that the risk of explosions is reduced. It is crucial that you eliminate one or more component of the ignition triangle to minimize the chances of an explosion. The 3 protection methods listed below are widely used in hazardous locations, in the process control industry:

Before we delve a little deeper and understand these techniques, let’s take a quick look at the role electrical enclosures.

Electrical enclosures are cabinets containing different electrical components such as switches, sockets, plugs, knobs, transformers and controls. These keep the surroundings safe from any kind of electrical hazard. Such enclosures are resistant to spark and shock and they have a high tolerance to extreme temperatures. They must be used in hazardous locations as they keep an interior explosion from spreading to the external environment and damaging life and property. Let’s see how they are relevant in the Containment method of protection:

If you live in a stormy or cataclysmic area, then you know how important it is to have a plan – an escape route, a first aid kit, a survival backpack, and anything else you might need to get by when push comes to shove. A few weeks ago a nasty storm hit our area, knocked over some power lines, and took the transformers with them. This left us and our neighbors without power for the better part of two weeks. Once the dust settled and we recovered, it was time to invest in a backup generator.

The Perfect Plan B

There are loads of generators to choose from, with as many makes and models and your local car dealership. It used to be just a pull chord engine you’d plug the necessities into like the fridge and stove. Now you can plug your whole house into one if you need to. The choices are far beyond what is expected. The man at the store helped me wade through all the options, weeding out all the unnecessarily bulky models and the ones too small to power the house.

After all the work, we finally found what we needed. Now we just had to find out how to get it home and hooked up. No amount of do-it-yourself material was going to help me here. I needed a professional. The man at the store gave a good recommendation and just like that the project was underway.

In a nutshell, generators have come a long way. Having a professional doing the job is an absolute must; most of the terminology was foreign and there were wires everywhere. But after a day or two the job was done, and the generator sits nicely in the backyard, waiting for bad weather to strike again. We’ll be ready this time.

We wrote the UK and China) have been developing this lighting-based data transmission, which could revolutionize the way we connect to the internet.

One of the advantages of Li-Fi is its ability to function in electromagnetic-sensitive areas such as in aircraft or nuclear power plants, without causing interference. Additionally, Li-Fi signals cannot travel through walls, a welcome feature for many users who wish to increase their digital privacy, although this comes with its obvious drawbacks, such as difficulty in creating “blanket” wireless coverage.

A burnout, in electrical terms, is a drop in voltage across an electricity supply system. It can be spontaneous (unintentional) caused by disturbances in the grid, or intentionally caused during emergencies when the load needs to be reduced in order to prevent blackouts. The lower voltage causes lights to dim, leading to the name “burn out”.

Spontaneous burnouts usually cause voltage to drop for only a short period, while the intentional ones can have effects lasting anywhere from a few minutes to a few hours.

A burnout can prevent some electrical devices from getting harmed by power loads, but others can actually get damaged severely. Here are some facts that you should be aware of:
