Mechatronics, or mechatronic engineering combines mechanical and electrical engineering to design innovative products and systems. These systems must rely on mechanical and electrical components working together in harmony.

The list includes DVD disc drives, anti-lock braking systems, manufacturing, electric motors and clothes dryers, among others. These devices require electronic controls and feedback systems to interact seamlessly with their mechanical design.

Motor control systems operate by using a programmable logic controller or PLC. This system allows advanced programming and algorithms to dictate a motor’s behavior. Therefore, they can be programmed to control multiple motors or VFDs. A robotic arm or a large factory machine is a good example of this.

In addition, PLCs can accept inputs from a wide range of sensors and switches. This allows precise feedback from the machine it controls. Furthermore, it executes built-in software.

The smallest high-precision motors, DC motors, found in computer hard drives and DVD readers. Due to their miniaturization, they can be easily controlled by computer software to perform nearly any imaginable task. A battery powered quad-rotor drone offers us a prime example of DC motor control. Accelerometers and gyroscopes feeding data into a computer controller adjust the speed of each motor independently to keep the drone flying level.

A simple technology that combines electric motors with feedback control, known as servomechanisms, provides valuable information. They utilize a small electric motor, gearboxes, and a potentiometer to produce accurate position feedback to the motor itself. This ensures that the motor has moved to the correct position. Thus, precise movement control of a motor is possible. Applications of servos include RC car steering, fly-by-wire systems in aircraft, robotics, and industrial control valves.

Servos communicate with computer systems, allowing them to be part of larger mechatronic systems, so they can be controlled by PLCs and computer algorithms.

The field of mechatronics constantly evolves. Therefore, as it does, it incorporates cutting edge computer software and mechanical design, bringing to life new inventions. These breakthroughs make modern-day living much easier and more fun.

As summer sets in, along come the hot temperatures. Staying cool while having fun is going to be a necessity. How will you find ways to keep yourself cool, your house or office? It will be important to be aware of the ways you can save on energy while keeping temperatures down.

In this high-tech age, our gadgets can be essential lifelines. Smartphones, tablets, laptops and other devices are what help us connect with colleagues, avoid boredom and find our way from Point A to Point B. They can seem almost magic, but there’s one great equalizer that limits them all: battery life.

If you depend on your devices, keeping them charged is critical. But life doesn’t always work that way; you often can’t stay tethered to an outlet for an hour or more, and sometimes an outlet just isn’t there when you need it. And that’s where portable chargers come in.

Power to Go

A portable charger is like a second battery for your device, and some models hold enough juice to charge your devices a few times over. Charge your trusty portable charger at the same time you charge your phone, and you can walk around with double, triple or even quadruple the battery life you’re accustomed to.

The portable charger market is getting bigger all the time, so choosing a model can feel a little overwhelming. But that also means that if you know what factors to consider, you can find the perfect charger for your needs.

When shopping for a portable charger, consider these key attributes:

Size and weight: The smallest portable chargers are about the size of a tube of lipstick, while others may be as big as your hand and nearly an inch thick. Similarly, some are virtually weightless, compared to larger chargers that are even heavier than they look. You might want one of each -- one for your pocket and another for your briefcase.

Charge capacity: There is a huge range of available charging capacities -- that is, how much energy each charger can store at once. Capacity is measured in milliamps per hour (mAh), and models can range from around 3,000 mAh (enough to double the battery life of your smartphone) to more than 20,000 mAh, which is ideal for laptops.

Charge speed: Nobody likes to wait, and some charger manufacturers capitalize on this by emphasizing charging speed in their designs. It’s common for chargers to be marketed based on how quickly they can charge common devices, so look for this detail if speed is important to you.

Connections and cords: Virtually all portable chargers have a USB port, but some may support several types of connections and come equipped with a variety of cords.

Special features: While many chargers just stick to Job #1, others may have features like built-in flashlights or emergency alarms.

Durability: Portable chargers are particularly popular among those who like to go off the beaten path while remaining connected. That’s why some manufacturers make their chargers waterproof, shatterproof and otherwise tough as nails.

Price: When price is an object, you’ll be able to find some chargers for as little as about $10. For the most durable chargers with the highest capacities, prices can exceed $100.

When you need a recharge on the fly, portable chargers are clearly the way to go. But if you ever have trouble getting a charge in your own home, don’t hesitate to reach out to your professional local electricians!
