Video Intercom System is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public telephone network (Azori 2016). Intercoms are generally mounted permanently in buildings and vehicles. Intercoms can incorporate connections to public address loudspeaker systems, […]

Secondary optics are those optics which exist outside of the LED package, such as reflector, TIR lenses, Fresnel lenses, and pillow lenses. Secondary optics are used to create the desired appearance and beam pattern of the LED signal lamp. LEDs generally emit light at a 120-degree viewing angle. LED applications that require more focused light […]

In electrical power distribution, a busbar (also spelled bus bar, or sometimes as buss bar or bussbar, with the term bus being a contraction of the Latin omnibus, "for all", is a metallic strip or bar (typically copper, brass or aluminium) that conducts electricity within a switchboard, distribution board, substation, battery bank, or other […]

Virtual training is a simulated virtual environment which is created to assess the capabilities of trainees to select the right resource. The virtual training simulation is of two kinds, namely instructor-led training and non-instructor-supported training. Simulation, by definition is a process of imitation of an operation of a real world system or […]

Earthing Lightning Protection System encompasses external lighting protection, effective earthing and transient overvoltage protection (surge protection of electronic systems), etc. Lightning protection systems are the modern development of the innovation pioneered by Benjamin Franklin: the lightning rod. Today, lightning protection systems are in […]

“Sensor fusion” means combining two or more sensors into one single system. This report studies the Sensor Fusion System market, Sensor fusion is combining of sensory data or data derived from disparate sources such that the resulting information has less uncertainty than would be possible when these sources were used individually. North […]

Home Appliance is electrical/mechanical machine which accomplish some household functions, such as cooking or cleaning. Home appliances can be classified into: major appliances, small appliances, and consumer electronics. This division is also noticeable in the maintenance and repair of these kinds of products. Major appliances usually require […]

The Ceramic Trimmer capacitor is the parts that its capacitance can be changed freely. There are two types of ceramic trimmer capacitors based on the packaging methods: SMD Ceramic Trimmer Capacitor and DIP Ceramic Trimmer Capacitor. The Ceramic Trimmer Capacitors are used in some applications that generally have no need to adjust again after the […]

LTCC Ceramic Substrates is a type of multilayer ceramic substrate that made by lower temperature (usually from 850 to 900℃) firing process than general ceramic firing process by adding glass to alumina. It makes it possible to use low resistive conductor as conductor patterns in. Currently, the LTCC Ceramic Substrates industry concentration is […]

Digital Panel Meter is an instrument that displays an input signal in digital form. Many digital panel meters also include alarm options as well as the ability to connect and transfer data to a computer. Digital panel meters are usually available with an Ethernet option which allows the digital panel meter reading to be accessed across a local area […]
