As of 2016, pico projectors are sub-1 pound with internal batteries and have an output of no more than 100 lumens with many producing 10 to 50 lumens. Many of the pico projectors are available on Amazon, the US website; however, pico projects from major brands including Vivitek, Optoma, and Sony are not available online. Most of the pico projectors run up to 2 hours on their internal batteries and have 6 or 12-volt chargers and adapters. Though external battery packs option is available, it is not offered by the manufacturers.

Night vision devices collect ambient light, which includes moonlight, starlight or infrared (IR) light through the front lens of the device. This light is made of photons. It is converted to electrons by passing it through a photocathode tube. The electrons are then amplified through a chemical and electrical process. After that, the resulting light is thrown against a phosphorous screen that converts the electrons back to the visible light, which the user sees through the eyepiece. The image is a clear, green-hued, amplified recreation of the scene. It is green because of the phosphorous screen, which converts light to green. This is because human eyes are more sensitive to green light than to any other color.

变频器市场国产品牌与国外品牌，无论在技术、加工制造、工业设计等方面还是在资金实力方面，都与国外品牌存在差距，目前仍然无法撼动国际品牌的主导地位。变频器领域，低压变频器市场小幅下滑且市场集中度有所下降，除了两大巨头 ABB、西门子占据 21%的市场份额，3-10名的市场占比率相差不大，外资品牌在国内变频器市场的占有率仍维持在 60%-70%。而国产品牌 2016 年内虽有上升趋势，但是市场占比率提升方面仍不明显，如汇川市占率为 6%，位列第三位；英威腾为 4%，跻身前十大低压变频器厂商。

Meat and poultry processing equipment is used by manufacturers of meat and poultry products for processing meat using techniques such as blending, homogenization, pasteurization, and filling. Processing of food helps in removal of toxins and preservation. Processed food offers advantages such as enhanced taste, low risk of contamination, enhanced shelf life, and a high degree of portability.

The global massage equipment market was valued at $18.32 billion in 2016, and it is likely to grow at a CAGR of 5.88% to reach $24.38 billion by 2021. The market was dominated by the Americas in 2016, which accounted for a revenue share of 45.42%. The demand for handheld massagers has increased in the past three years because of the rise in awareness among the global population about professional and premium massagers. Professional massagers are known for providing quality results to individuals and are comparatively expensive. Massagers are primarily prevalent in the market based on their massage mechanisms such as natural, organic, acupressure, shiatsu, ultrasonic, hypoallergic, homeopathic, and aromatherapy. Inexpensive electric massagers attract much of the end-users in developing countries. Countries like the US and the UK are the major revenue contributors to the global massage equipment market.

Managed industrial Ethernet switches are increasing their presence in the industrial communication market due to their network prioritization capabilities and due to the increase in the highly critical process applications. The functionality of an Ethernet switch is defined by IEEE 802.1D, which describes the architecture and the set of functions distributed throughout this architecture. In addition to the handling of user data communication, these switches also provide a set of network managementrelated functionality.

Various industries, ranging from coal desulfurization to metal production have been using magnetic separation as an essential part of their processes for decades. Magnetic separation filters are used to remove magnetic impurities in continuous flow processes. Magnetic separation techniques like high-gradient magnetic separation (HGMS) have broadened the application base of MSE to industries such as food processing and industrial wastewater treatment. In addition, the applications have expanded to include niche industries like biotechnology where batch-scale magnetic separators are used for the purification of complex mixtures in cell separation, protein isolation, drug delivery, and biocatalysis.

Marine outboard engines are generally used in powerboats. Almost all powerboats are now equipped with either inboard or outboard engines. The demand for outboard engines is more than inboard engines. In Europe, 80% of the total engines used are outboard engines. In the US, the demand for outboard engines is on the same line as in Europe. In Europe, the demand for diesel engines is more, whereas the American market is dominated by gasoline engines. Another major difference between these markets is that consumers in the European market prefer low power output outboard engines, whereas consumers in the US prefer high power output outboard engines.

Laser refers to light amplification by stimulated emission of radiation, which produces a coherent, collimated, and monochromatic beam of light by exciting atoms to a higher energy level. Lasers are distinguished from other light sources by their coherence. Spatial coherence property of laser enables it to stay narrow over great distances and allows it to be focused on a tight spot. As a result of these properties, they are widely used in applications such as laser pointers, laser cutting, and lithography. Lasers are classified based on the type of lasing medium they use such as gas, optical fiber, solid state, and semiconductor.

LFPs (also known as wide-format printers) are printers that support maximum print roll width of 18 inches to 100 inches. The major areas where LFPs find application include print banners, posters, backdrop for theaters, constructional designs, and different other large-format artworks. Most of the LFPs available currently are based on inkjet printing technology. Aqueous, solvent, dye sublimation, UV, and pen/plotters are the technologies used to transfer ink in LFPs. Advances in technology across different components of LFPs, such as ink and working mechanism, are the factors that have enhanced their efficiency and productivity. The global LFPs market is witnessing an increase in demand from application areas, such as advertising, textile, and vehicle wraps, and these are expected to be the key factors driving the market growth during the forecast period.
