Relays are very important electrical devices, and choosing the proper one is very crucial. Relays usually incorporate an electromagnet, which is activated by a current or signal in one circuit to open or close another circuit. There are numerous factors that should be taken into consideration when choosing the proper relay for a job, including the contact system, magnetic system, the environment, and the physical requirements for installation.

Technology and Social Isolation

Is it possible for technology to play a role in helping individuals overcome social isolation?

The idea that robots can aid in the conquering of social isolation is not far fetched. “Robots” are quickly becoming a sort of ‘interactive carrier’, if you will, in helping individuals with learning and coping processes. Just within the last few months, we posted an entry about how robots are helping with the developmental growth and teaching of young children. Now, it seems, scientists and researchers in England are attempting to shed light on social isolation. Whether it’s sequestration due to a disorder or a handicap, these robots may make it easier for those to communicate with others and participate in social settings.

Solid State vs. Electromechanical Relays

When it comes to selecting relays, two in particular really stand out. Here is some general information on what makes each of these relays stand apart from one another.

A relay is an electrical device that usually incorporates an electromagnet, that is activated by a current or signal in one circuit to open or close another circuit. Much like a message is “relayed” from one person to another, the electromagnet sends messages through the current or signal within the circuit and gives directions.

Using Technology to Protect America’s Southwest Borders

Technology is playing a huge role in protecting the US border from those trying to smuggle illegal substances and people into the country.

Every year, countless hopeful migrators try to illegally enter the United States by crossing the border of the country’s south western states –Arizona, New Mexico, Texas, and California. Often times, they are trying to smuggle dangerous materials, such as drugs and weapons as well.

The High Cost of Green Energy

Is American Farmland Ultimately Paying the Price?

Are cornfields taking over America’s prairies?

In 2010, the number one use for corn in America was not for sustenance, nor was it for produce purposes.

It was for fuel.

There are several toy robots in production that are being geared specifically towards young children in the hopes of teaching them computer coding and programming. The innovative minds behind these models were looking for a way to project early learning and creativity to the youngest of minds through the simplest of ways – playing with toys. The result was Play-i, and was founded by engineers from Google, Apple, and Symantec.

Google Glass – The Next Great Gadget, or Another Hazardous Distraction?

Google Glass – it’s a futuristic device, and, no doubt, an image that came to mind many years ago when people imagined what crazy implements the future would produce. A computer – that is worn – on your face, like glasses. An optical head mount display (or, OHMD) that allows you to basically do anything that you deem necessary in that exact moment in time. Convenient? Absolutely. Google Glass is designed to display everything that a smartphone already does, just in a useful hands-free format.  One feature that is garnishing a lot of buzz is the on-command speaking function. Are you lost and need directions? Simply speak, and Google Glass can immediately find out where you need to be. Want to take a photo? Command Google Glass to do so, and boom – your photo is right in front of you.

An Introduction to Voltage Regulators

Voltage Regulators

Voltage Regulators

A voltage regulator is found in electronic devices, and it is used to maintain the voltage of the power source so that it stays within acceptable limits. Voltage regulators are designed several different ways – it could be a simple “feed-forward” design, it may include negative feedback control loops, or it could use an electromechanical mechanism, or electronic components. Also, voltage regulators may be used to regulate one or more AC or DC voltages, depending on the design.

LED Color

LED lights have become vastly popular and have gained worldwide recognition over the last decade or so.  LEDs have countless uses and are quickly becoming a favored choice for light sources. These lights are extremely reliable due to their long lasting power and brightness. LEDs are also very environmentally friendly. All of these characteristics combined are what makes LED lights the number one choice for many people when it comes to using them for projects, electronics, household needs, etc. LEDs are so reliable, in fact, that they are currently used to light up the world’s tallest spherical building. (the Globen Arena)
