Automatic gain control is a technique implemented in many consumer electronics that automatically adjusts the input levels of a system by inducing a portion of the output levels in the input terminals. Automatic gain control is used in a wide variety of technologies, including telecommunications, navigation, audio/video recordings, and radio systems. Automatic gain control can also be seen in biological systems, such as the vertebrate visual and audio systems.   How Automatic Gain Control Works Automatic gain control is dependent on a loop in which the output terminals of a Read More

A patch panel is a panel that houses multiple cable connections. It is also known as a jackfield or patch bay. The back of the panel has wiring or other connective cabling that runs to disparate equipment. The front of the patch panel allows easy access to connect the different equipment with the use of short patch cables. Before automatic telephone switching became widespread, huge arrays of patch panels were used, in which early telephone operators would connect callers to their intended parties manually by plugging in a cable on Read More

Hypertext Transfer Protocol (HTTP) is a application based protocol or set of rules used to transfer files such as text, image, graphics, audio, video and other multimedia files on the World Wide Web. It sets the guidelines on how files and messages are set up and transmitted, and how web servers and browsers should act in response to various instructions. HTTP standards were developed and released as a result of a collaborative effort between the World Wide Web Consortium and the Internet Engineering Task Force (IETF). HTTP 1.1 is the Read More

Rhodium plating is a type of metal plating that prevents an object from being scratched or tarnished and improves the object’s color quality. Rhodium is a precious metal that is five to twenty-five times as expensive as gold and is used for plating jewelry and other objects in order to make them brighter, smoother, and last longer. It is too brittle to be made into solid jewelry, but rhodium plated gold or silver jewelry is much stronger and looks much better than their non-plated counterparts. How Rhodium Plating Works Typically, Read More

An HD Upconverter (High Definition Upconverter) is a device that converts the digital data embedded in DVDs into a format that can be directly viewed on a HDTV (High-Definition Television) without an intermediate conversion to an analog signal. An upconverter also digitally enhances and enlarges the standard lower resolution of some DVDs and ‘upconverts’ it so it can be seen clearly on a HDTV. In addition, some of the modern HD upconverters can even convert the frame rate of 35 mm movies to that of HDTV’s so that flickering is Read More

Playstation 3 (PS3) users often encounter the PS3 DNS error when they have problems connecting the system to the Internet. The causes for the PS3 DNS error varies. Since the system does not provide any additional specifics on the root cause, users are forced to take a number of troubleshooting steps in order to fix the problem and be able to enjoy online games and movies again. How to Fix the PS3 DNS Error Step 1 – Reset the modem that connects the PS3 to the Internet. To do this, Read More

An air scrubber is a device that removes particles, gases, or chemicals from the air in a specific area. Air scrubbers are very important in some industries as workers are frequently exposed to harmful substances. Most air scrubbers are made for a specific type of air purification but some are made to handle particles, gases, and chemicals at the same time. Air scrubbers range dramatically in capabilities, functions, and filters, but they all perform the general task of removing harmful substances from the workplace. How do Air Scrubbers Work? Air Read More

Fraxel laser is a technology that is used for dealing with age spots, melasma (Mask of Pregnancy), sunspots, wrinkles at various parts of the face, upper lip lines, sun burned skin, and acne scars. Today it is the prime technology used for treating acne scars, as it barely creates any downtime. Initially developed and implemented in late 2003 and early 2004, Fraxel laser treatments are popular today as it allows any patient to own a smooth, youthful, and rejuvenated skin. Inside the Fraxel Laser Technology The Fraxel laser uses a Read More

An inclinometer is a device that measures both positive and negative slopes. Inclinometers are also known as tilt meters, tilt indicators, gradiometers, declinometers, clinometers, etc. They measure tilt, levelness, and angles. Most inclinometers are based on conversion formulas that allow an angle to be calculated across a specific distance. While early inclinometers were based on fluids, most modern inclinometers use digital sensors. How Inclinometers Work Early inclinometers used a device that had a flat base and an interior container of water or other fluid. Because the container was marked to Read More

A typhoon is nothing more than a hurricane that occurs in the North West Pacific Ocean. The same conditions that cause a hurricane in the Atlantic ocean that hit the United States every summer are the ones that cause a typhoon. However, a typhoon does have a series of specific “rules” to exist and therefore, the causes of a typhoon are a bit more particular than with a hurricane. Typhoon Causes The first cause is warm water. When there is an abundance of warm water, there is a considerable amount Read More
