A breast pump is an automated or a manual device that can extract milk from the breasts of a lactating woman. Manual breast pumps are executed manually by hand movements to extract milk, electrical breast pumps are powered by electricity for automatically extracting breast milk, and battery-powered breast pumps are powered by batteries. Most of the breast pumps permit direct assortment of pumped breast milk into a bottle, which can be used for storing and feeding new-born babies. Moreover, breast pumps may be attributed to stimulate lactation for females with irregular milk source.

An LED is a semiconductor device/light source that emits visible light or infrared light when an electric charge passes through it. LEDs are primarily used as indicator lamps and other lighting purposes, such as on billboard signs, television remotes, and in the brake lights in automobiles. In the early days, LEDs would only emit a low-intensity red light. Currently, however LEDs are available across the visible, ultraviolet, and infrared wavelengths. They work on the principle of electroluminescence, wherein the color of illumination is determined by the energy band gap of the semiconductor. A UV LED displays an ultraviolet light; its wavelength is lesser than 400nm. UV LED's compact nature and superior performance has led to its application in UV curing, counterfeit detectors, scientific instruments, and much more.The Global UV LED market is currently witnessing a high growth rate. The APAC region dominated the market in 2012 and accounted for a market share of 39.4 percent; the APAC region was followed by Europe, North America, and ROW. The Global UV LED market is expected to grow at a CAGR of 44.3 percent during the period 2012-2016.

Aircraft electrical systems are used to generate, control, and distribute the electrical power throughout the aircraft. The electronic flight instrument integrated in the new generation aircraft completely rely on the electrical power system. Some of the major functions of an aircraft electrical system include controlling and operating essential aircraft systems, operating passenger services systems (such as cabin lighting and operation of in-flight entertainment systems), as well as controlling aircraft flight instrument systems. The products that come under the aircraft electrical systems are auxiliary power units, aircraft batteries, engine-driven generators, motors, power conversion, and distribution systems. Devices used to provide energy to large aircraft other than for the propulsion are known as auxiliary power units. To run the electrical systems of the aircraft, auxiliary power units generally produce 115V at 400 Hz of power. Auxiliary power units provide power through single-phase systems or three-phase systems. Aircraft batteries are the final source of backup power, but the power usage is limited due to the short life of the battery. Engine-driven generators produce power which is used to supply power to the aircraft.
