There are a number of vibration sources throughout the world. In most cases, these movements have undesirable effects on things used in daily life, such as buildings and vehicles. Vibration isolators reduce or eliminate the effects of vibrations on equipment and structures. These devices are commonly referred to as shock mounts, snubbers, machine mounts, and …
The four dimensions are concepts in mathematics to describe different shapes. It is easy to understand a first dimension, second dimension and third dimension shape. All things are 3D in the world, but images can be 2D. A first dimension is as easy as a line. However, what is the fourth dimension? The fourth dimension …
A laser printer unlike an inkjet printer uses a laser light beam for printing operations. It is also distinct from other printers because of its exceptional printing speed as well as highly accurate rendering. It utilizes a xerographic (a process of creating an image by the action of light on a specifically coated charged plate) …
Ocean currents are one of the main factors that affect climate. Other factors are proximity from the equator, distance from the sea, direction of prevailing winds and relief (mountains). But, for the most part, ocean currents act as one of the most important factors that influence the climate. And the reason why is because a …
Electrotherapy is a medical technique in which an electric current is used to perform a wide variety of tasks associated with pain, neurological disorders, muscle-related conditions, and drug delivery. Electrotherapy includes a range of medical techniques, some of which are under much debate and criticism. While electrotherapy itself is an accepted form of medical treatment, …
As society is trying to slowly ween itself off of oil-dependency, the search for alternative fuels continues. One source of alternative "fuel" that already exists, however, is the electric motor. Electric motors are commonly found in vehicles, toys, and other electronic devices but there is still a campaign to improve the quality and efficiency of …
When the Earth begins to get too hot, the water increases in temperature. As the water continues to get hotter, it begins to undergo a phase change in which water turns to gas. The water droplets turn into water vapor because the temperature has caused the individual water molecules to speed up considerably. This process …
Augmented reality is one of the newest innovations in the electronics industry. It superimposes graphics, audio and other sense enhancements from computer screens onto real time environments. Augmented reality goes far beyond the static graphics technology of television where the graphics imposed do not change with the perspective. Augmented reality systems superimpose graphics for every …
A linear actuator is a mechanical device that makes a linear motion, usually via a hydraulic pump or electromagnetic gear. Other forces can be used to create linear motion. The different types of linear actuators include screw, wheel and axle, cam, hydraulic pump, pneumatic, piezoelectric, and electro-mechanical. Linear motors, wax motors, and telescoping linear actuators …
In the world of ice hockey and ice skating, there is nothing more important than maintenance of the ice. Failure to properly take care of an ice rink could result in broken bones, property damage, or the loss of a game. In order to efficiently care for an ice rink, ice rink owners spend large …
