Fire Alarms: an Important Piece of the Safety Puzzle for All Facilities

Fire Alarms: an Important Piece of the Safety Puzzle for All Facilities

One of the most valuable safety components of any business are alarm sirens. Whether we’re talking about fire alarms, intruder alarms or any other safety hazard alarms, protecting the property and inventory of your business is required by law. By necessity, no two systems are the same, each one of them is custom-installed and tailored with specific business processes in mind. For instance, a system made for a lodge will be vastly different than the one intended for a warehouse. The focus on the special circumstances is what differentiates these systems from the basic smoke alarms that are sold in hardware stores. (more…)

The History of Diesel Engines and DPF

The History of Diesel Engines and DPF

Since the combustion engine was invented back in 1893, diesel powered engines and generic spark-driven combustion engines have been competing for the best engine spot among engineers all over the world. Since the past century, these technologies have been at an uneasy peace with spark-driven engines and light-weight engines dominating the personal marine, early aviation and personal transportation fields, while the heavier diesels have been the engines of choice for ships, submarines, trucks and locomotives.

However, in the past few decades, diesel engines have become extremely competitive in automobile manufacturing. In Europe, half the newly manufactured cars now run on diesel. You may ask why? Well it’s simple – they’re more reliable, efficient, run cooler, last longer, diesel fuel is safer, they’re more easily turbo-charged, produce less carbon monoxide, accept synthetic fuels and so on.

If your car runs on diesel, and you’re considering replacing your exhaust system, one thing to consider is installing a DPF back exhaust as it removes soot or particulate matter from the exhaust gas of the engine. The diesel exhaust can be produced by the engine which contains particles that can be comprised of the fuel type or consumption rate of the engine.

The exhaust from diesel is a carcinogen, which is the product of incomplete combustion of the diesel fuel. These particles can include small nanoparticles, which can worsen the pollution in the atmosphere and can be harmful to the health. The DPF back exhaust filters can capture more than 95% of the harmful soot. If the DPS is optimal, soot emissions can be lowered to 0.001g per km or even less. This technology was first considered in the 70s due to the concerns about the impact that inhaled particles had. They’ve been used on non-road machines since the 80s and half a decade later they were implemented in automobiles as well.

At this point, the diesel engines, as aforementioned, have become the preferred choice of many people around the world. And while there were no regulations about this in the past, a lot of people still decided to go for this environmental-friendly solution. Nowadays, however, a lot of countries have implemented a law which enforces the use of DPF, so now is the right time to invest in one and stay ahead. By investing in a DPF back exhaust you are supporting the environment and making a statement, regardless whether in your country or state the laws enforce it or not.

The Timeline of Cameras: From the Camera Obscura to Sophisticated Digital Cameras

The Timeline of Cameras: From the Camera Obscura to Sophisticated Digital Cameras

Whenever I hold and admire the capabilities of my digital SLR camera, I think about the history of the camera and the large number of brilliant inventors who helped make the practice of photography extremely easy and enjoyable. In order to see how cameras have evolved during the last four hundred years, I’ve decided to create a timeline of the most important camera-related events so far. All right, let’s start the journey.

1600s: The Birth of the First Portable Camera Obscura

The foundation of the camera obscura, the modern camera’s forerunner, was built when ancient Chinese and Greek philosophers realized that when light travels through a pinhole into a darkened room or box, an inverted image of the outside world is produced on to a screen inside. Yes, the first camera obscura was more of a projector than a camera, for the image needed to be traced by the observer in order to be captured. The very first mobile camera obscura was made in the late 1600s and was used as a drawing aid.

1800s: The Time of Plate Cameras

In the year of 1826, the French inventor Joseph Nicéphore Niépce created the first permanent photograph using heliography, a photographic process he invented. Back then, cameras were plate ones – they were made up of a pair of nested boxes with a lens at one end and a removable ground glass focusing screen at the other. The images were recorded on light-sensitive plates.

1920s: The Reign of the Leica I Film Cameras

Although roll film was developed in the late 1880s by George Eastman (the founder of the Eastman Kodak Company), the first mass-produced 35-mm film camera named Leica I was launched in the year of 1925 at the Leipzig Spring Fair in Germany. This camera wasn’t the first 35-mm one, but it was the first camera that made the 35-mm film format the most popular one ever.

1948 – The Introduction of the Polaroid Land Camera

The first commercially available instant camera was introduced in 1948 by Edwin Land (one of the founders of the Polaroid Corporation). The Polaroid Land Camera became an instant hit, as it gave its users the amazing opportunity to take a shot and immediately get the photo printed on a special paper. Polaroid cameras are still extremely popular.

1975 – The Invention of the First Digital Camera

41 years ago, the American electrical engineer Steven Sasson invented digital photography (the process that allows us to take pictures with our smartphones) and made the world’s first digital camera. Mr. Sasson’s invention took digital pictures and stored them on a cassette tape.

2010s: The Era of DSLR Cameras

Today’s world of photography is ruled by DSLR cameras. Since nowadays there are so many reputable digital SLR camera manufacturers and sellers, finding a sophisticated and affordable digital SLR camera is not a difficult task. High-end DSLR cameras, such as the Nikon D750, offer excellent image quality, come with built-in Wi-Fi connectivity, and are reasonably priced.

Infrared Heating Mat: The Ingenious Product You Didn’t Think You Need

Ah, the perks of technology. I know for sure I’m not the only geek that’s obsessed with keeping up with the world of inventions and buying most (if not all) latest electronics that my life simply can’t do without. Spending most of my time in the company of gadgets and devices both at work and at home, my sedentary lifestyle had started taking its toll without me realizing. Apart from the frequent headaches, eyestrain and occasional wrist aches, my back was killing me. I had my share of painkillers and unsuccessful therapy treatments that involved some odd and demanding exercises and it seemed like my back pain was to stay my constant companion.

But the camera is not the only element of a photographer’s gear that has come a long way ever since it was invented. As the design and the functionality of today’s most popular DSLR cameras are being constantly improved, photographic equipment manufacturers and sellers have started offering their customers a vast array of modern camera tools and accessories. Sure, our great-grandparents used tripods and large camera cases, but we need many more camera accessories to get the most out of our expensive digital cameras. Camera batteries, battery chargers, memory cards, camera cleaning supplies, light reflectors, and camera straps are some of the most essential ones.

Nowadays, having in mind the fact that digital cameras are rather small and light, people don’t hesitate to seize the opportunity to capture the highlights of their vacations and camping trips by bringing their DSLR camera along with them. If you are one of them, then you should know that photographing the breathtaking sights you encounter during your stay in a foreign country or a forest becomes much easier when you have a camera strap. With the help of this accessory, you can stop worrying about damaging your camera and start focusing on finding the most flattering angle for your photo.

Light reflectors are another useful type of camera accessories. A set of these items can easily save the day when you are shooting outdoors on a sunny day, for this is when your camera’s flash is not going to work. Oh, let’s not forget to mention the importance of a camera cleaning kit. You don’t have to be a professional photographer to realize that cleaning your camera’s lens on a regular basis is highly advisable, which is why you should spend some money on a blower, a lens cleaner and lens tissues. Trust me, the satisfaction and the joy of marveling at your perfect, spotless photographs is well worth the cost.
