When it comes to crime, it’s evident that there’s an appeal to darkness. Less visibility means less chance of getting caught. The 2014 National Incident-Based Reporting System (NIBRS)—an annual Uniform Crime Reporting (UCR) Program publication that’s released by the FBI—includes detailed crime data, such as time of day and type of offense. More than 18,000 law enforcement agencies participate in the UCR Program and provide data voluntarily. NIBRS’ Crimes Against Persons data shows that of the 1,093,466 incidents reported in 2014, 562,104 (51.4 percent) were between the hours of 6 p.m. and 6 a.m. Crimes Against Property data shows a lower—yet significant—39.4 percent of 3,493,904 reported incidents taking place between those same hours.

In an attempt to lessen crime and increase energy savings, many cities and businesses have started replacing traditional high-intensity discharge (HID) lights with LED bulbs, light engines, and fixtures. These actions have paid off. In 2008, Los Angeles began a project to retrofit 215,000 lights with LED lights. Since implementation of the project, color-rendering indexes (CRI) than HID fixtures. CRI refers to how accurately a light source reveals the true colors of objects, people, and surroundings. The CRI of an HID bulb can range from zero (high-pressure sodium) to about 65 (metal-halide). LED fixtures are capable of having CRIs of 75 and higher. Lights with a CRI of 80 or higher are considered to show colors most accurately and increase visibility, which is especially important for security purposes and parking lot surveillance.

When you go through the process of buying a home there are many processes and inspections that you expect. There is an appraisal to know the value of the house for both the bank loan and the homeowner’s insurance, and then there is the general home inspection which tries to identify any possible problems with the home. Many things can come up during this general inspection from issues with the roof to problems with the breaker box. Consider the following reasons for hiring an electrician to do an electrical system inspection on a house before signing the final closing papers.

A home inspection when you’re under contract can be a really stressful process; you never know what a general inspection will find. There could be any number of hidden problems that aren’t easily visible in the home. This is definitely the case with the electrical system.

Concerns such as a recalled breaker box, non-compliant outlets, or simply the age of the house could merit requesting the services of a certified electrician. That way you will know that an expert has been consulted with and any necessary repairs made.

Unfortunately, a home’s electrical wiring is often hard to see as most of it hides in the walls. However, expert electricians have the tools and know-how to spot problems that may be overlooked. Problems in the electrical system can cause many bigger issues including being a fire hazard. Having an electrician check a home prior to purchasing can help to mitigate any risk down the line.

Don’t forget to have the electrical system thoroughly checked by a certified electrician prior to closing on a new home. Contact Electrical Gurus today!

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.
