The Power System Simulator market and its demand is increasing and growing on a regular basis all over the world. Relatively the growth is seen on the higher side in the Asia Pacific countries and in US due to new technological advancements being implemented. Adoption of IoT and Cloud Platform are considered to be the top most priority for the marketers creating a strong demand. Power system simulator is a kind of software that is utilized by engineers for simulation of power transmission networks under steady-state conditions and over period ranging from few seconds to many seconds. Apparently, the software is used for long-term power generation and power transmission expansion planning. In addition to this. The simulation system provides detailed perspective of the project time and saves a cost of implementation on a longer run.

Weapons which are specifically designed and are anticipated to be less probable to kill a living object than conventional weapons are known as non-lethal weapons. In some cases, where the use of conventional weapons such as gun, sword, knife, pistol, and others are prohibited, these weapons prove as an effective alternative for restriction of casualties. Non-lethal weapons are used in critical situations such as self-defense, battle sensitive zones, riots, and others. Non-lethal weapons are also used to control the movement of civilian population, to limit civilian access to restricted areas, to protest violence by mob, and others. These are also called less-lethal, less-than-lethal weapons, non-deadly weapons, compliance weapons, or pain-inducing weapons. Non-lethal weapons are primarily used by military organizations, law enforcement agencies, and civilians for selfprotection. The use of non-lethal weapons enables users to protect themselves and control the critical situation without causing any fatal damage to the targeted person.

A sewing machine is used to stitch the fabric and other pliable materials together with threads. The different parts of a sewing machine and its various functions help the Operator to know the functioning of a sewing machine. There are different types of sewing machine used in the manufacturing of garments and other articles. Some sewing machines are larger, faster, more complex, and have wide range in their size, cost, appearance, and task.

Solar Freezers are now used in several end-use applications such as households, dairy, research-labs, medicals, and more. It is a freezer that transfers solar energy into thermal energy for providing low temperature. The basic components present in solar freezer include solar array, panel support structure, battery (optional), and freezer. Solar-battery based and solar-direct drive solar freezer are the most common types used in different end-use applications.

Surge protection devices (SPDs) are designed to protect electrical appliances from voltage spikes. SPDs limit the voltage supplied to an electric device by either blocking or shorting any unwanted voltages above a safe threshold limit to the ground. They are used in automatic control buses, electric power supply networks, telephone networks, and various communication systems. The key factor that drives the SPDs market includes increase in demand for usage of electrical and electronics appliances in commercial & residential sectors. Moreover, high costs incurred due to electrical equipment downtime have also encouraged the adoption of SPDs as it provides safety in industries and in the domestic sector. The key factors that hamper the growth of this market are lack of awareness among small scale manufactures and competition from uninterrupted and non-fluctuating power supply systems. On the contrary, growth in awareness for need of SPDs, rapid industrialization, and power supply issues in developing countries are anticipated to provide lucrative opportunity for the market.

The global cleaning equipment market was valued at approximately $26.01 billion in 2019. The professional cleaning equipment market was $8.69 billion, and that for the consumer cleaning equipment market approximately $17.32 billion in 2019. Highpressure washers accounted for a 10.39% share of the global cleaning equipment market in 2019. Accordingly, the pressure washers that form an integral component of the cleaning equipment industry are expected to grow 1.29 times during the forecast period. For battery-powered pressure washers, the contract cleaning market is expected to shape the growth during the next five years.

Intravenous (IV) therapy helps to deliver medications, fluids, and other nutrients directly into the body through veins. IV therapy is used during lifesaving therapeutic treatment and in wellness treatment. Since ancient times, blood therapy has been around, and blood has been viewed as a therapeutic substance. However, lack of proper understanding of blood types, infectious agents, and the absence of ideal materials such as plastics held back IV therapy for centuries. Later, IV therapy became the fastest way of delivering blood products, medications, vitamins, or other vital fluids. IV therapy is usually provided to the patient with the help of an intravenous catheter, either through an injection with a syringe or infusion.
