“Smart Homes” Need Smart Routers

Today, our lives are filled with a plethora of “smart products” be it smartphones, smart televisions, or smart home products, all these gadgets vie for Wi-Fi connectivity and it has become vital to outfit your home with a good wireless router.

Some of the things you should consider when buying a wireless router are:

  • Number of people using the router
  • Coverage area size
  • Types of devices that will be connected

It is true that you don’t require the most sophisticated and pay for features that you will probably never utilize. But if you have many people competing for the bandwidth like playing online games or streaming videos, then a new and fairly advanced router can keep the peace at home and make a world of difference.

Choosing a router

Single- or dual-band: Some router models communicate only via a single radio band while others use two bands. Single-band routers are fairly inexpensive and are suited for activities such as internet surfing and connecting to social media. If you will be streaming live videos or are into online gaming, then you can go in for a dual-band wireless router. If you have multiple devices with extremely heavy network traffic, then you can use tri-band routers.

Wireless Protocols: Data is sent and received by Ethernet networks. The most commonly used Wi-Fi protocol is 802.11nand today, most of the home devices, smartphones and laptops use this protocol. So if you have a few devices sharing the internet access, the 802.11n router is appropriate.

Features: Wireless routers have a variety of features and the more the features, the more the cost of the router. You should look for a router that allows you to connect wired devices such as home automation hubs, PCs and storage drives.  Make sure that your router offers you parental control and security options for adequate safety.

Wi-Fi mesh networking systems: Wi-Fi networking systems are the best way to cover your entire home with Wi-Fi without the need for access points, range extenders and additional wiring. They make use of satellites or extension nodes to spread the Wi-Fi signal over a larger area.

Price: The price of the router is probably a very important aspect that will influence your purchase decision and the price of a router depends on the features offered and its performance.

The best router is one that has a good range, fast throughput speed, easy to set up and manage, good features and most importantly is easy on the pocket.

 

Lights For Mining

In the industry of mining, a miner must go to the depth of the earth to extract geological materials and valuable minerals. It is a very daunting task to dig out these precious minerals from the depth of the earth. One cannot imagine how difficult it must be for a miner to earn a livelihood in such difficult circumstances. But these working areas are very dangerous to the miner’s life. Since these are very dark places, there has been many cases where miners lost their lives due to explosions caused by methane gas ignited from the lamps carried by these miners. Thus, lights play a key role for these workers, without which there is no work, no wages, and no sight.

Thanks to advancement in technology, that nowadays things have become a lot safer and better for these miners with the invention of headmounted lights. The best part about these lights is that you just need to wear them instead of holding them. These cap lamps are also lighter in weight in comparison to the traditional lamps, which makes it easier for a miner to travel down the mines. But these lighting products need to be reliable and resilient because of harsh conditions in these mines.

Features Of These Lights

These are usually LED lights that have replaced the traditional lamps which would consist harmful gasses like halogen and neon. These have great longevity and power saving capacity. These lights are also environment-friendly and have great efficiency.

These are dependent on rechargeable batteries. These batteries have a large capacity and thus illuminates for a longer duration. Some of the most key features of these lights are that they are dust proof, impact proof, explosion proof and waterproof which makes them reliable and durable.These are usually made from materials which are flame retardant. These lights are not only safe but also very cost effective.

Unwinding The Working Of An Accelerometer

Acceleration is simply the rate of change of velocity with time. It is based on the Newton’s second law of motion, which states that acceleration is the net result of all the forces acting on an object. For any machine which moves, this is an essential parameter to be monitored and controlled for its smooth functioning. A simple and most popular illustration of acceleration is the change of speed of a moving car.

What we observe is not proper acceleration

Taking the above example, a car moves forward or backward or turns circular and the passenger inside it feels the force in three directions every time. This is coordinate acceleration, defined from the perception of the observer. When acceleration is measured as that experienced by the object, it is known as proper or physical acceleration. This is measured by a machine called accelerometer.

The underlying technology

Accelerometer measures g-force, that is, acceleration with respect to free fall experienced by the object. When an accelerometer is kept at rest relative to the Earth’s surface, it indicates a value of approximately 1 g upwards. It is because the machine measures the relative upward acceleration of any point near the surface by keeping a freely falling object near the surface as the local inertial frame, relative to which the accelerator measures. This is gravity offset and it has to be subtracted to obtain the value of acceleration due to motion with respect to the Earth and corrections should be made to remove the effect of the Earth’s rotation.

Applications

An accelerometer is applied in a variety of sectors like production and engineering, life science and medical technology, transport and navigation, electrical, mechanical and other industries, civil construction and structuring etc. It has a futuristic application in all the industries and automobiles; to monitor, analyze and give indications of possible faults in instruments and machines on which it is mounted.

A data collector collects the measured data of the machine vibrations and is fed to analysis software which then signals for probable maintenance by the technician or engineer. This method helps to improve machine performance, production speed, and easy repair and has become a distinguished industrial process.
