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.

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.

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
