Soft starters are devices that are used to protect motors from large current fluctuation or inrush. The current inrush or spikes affect the performance of the medium and low voltage motors. Soft starters help in a smooth start and stop functionality of motors, which in turn increases the motors work life and the overall efficiency of the motors. The starting time for motors depends on the initial load, inertia, and torque. As in most cases, the starting current is higher than the rated operational current of the motors, it becomes essential for having a proper motor control center (MCC) in place, which can provide an adequate supply of current/voltage for the smooth functioning of the motors. There are different techniques used for motor control. Based on the motor power range, application, torque, and speed of the motors, different devices are used to create a smooth stop and start function for the motors.

Electric motors are electromechanical devices that convert electrical energy into mechanical energy. Electric motors are generally classified as alternating current (AC) motors, direct current (DC) motors, and other motor types. AC motor converts alternating current into mechanical energy. Electric motors are widely used in both discrete and process industries and have incorporated major technological advances, thereby creating a considerable demand among end-users. The development of efficient motors and the need for low power consumption motors are generating a scope of industrial growth for the market. Electric motors are widely used in industrial equipment, ranging from light-duty to heavy-duty applications.

Time of flight (ToF) is a term that denotes various methods used to calculate the time that an object, particle, or wave takes to move through a distance within a medium. A ToF sensor is considered to be an appropriate input device to both stationary and portable computing devices. This sensor is an important component of ToF cameras, which are used in a variety of sectors including automotive, industrial, healthcare, smart advertising, gaming, and entertainment.

Owing to the increasing number of accidents in industrial areas, the need for explosion proof equipment is growing. Explosion proof equipment includes electrical and nonelectrical equipment used for insulating machines to prevent explosions caused by sparks. The amount of damage occurring due to a spark and gas leakage is huge. Ready-to-use mechanical equipment that can prevent damages and are easy to handle are preferred. Explosion proof equipment consists of various construction materials that are installed in industrial buildings and shop floors during their construction. In addition, there is mechanical equipment used as preventive devices in industrial machines and buildings. Metals like stainless steel, copper aluminum alloy, galvanized steel, silver, and aluminum are used as explosion proof metals. These metals can be used for the construction of industrial machines and act as insulator coatings.

Microwaves are electromagnetic waves that have wavelengths in the range of 1GHz to 300GHz. Microwave devices can generate, amplify, modify, detect, or measure microwaves or voltages with microwave frequencies. There are two types of microwave devices: solid-state devices and vacuum-tube-based devices. Semiconductors, such as silicon (Si) or gallium arsenide (GaAs), are used in solid-state microwave devices. Microwave devices are mainly used in communication, navigation, radar, radio astronomy, heating, and spectroscopy applications. Backward diodes, Gunn diodes, IMPATT diodes, Schottky diodes, tunnel diodes, varactor diodes, transistors, and monolithic microwave integrated circuits (MMICs) are some of the predominant microwave devices in the industry.

Molecular cytogenetic techniques are used for the diagnosis of several diseases such as leukemia, cancer, chronic diseases, and certain genetic disorders. Previously, conventional cytogenetics were only used to detect chromosomal abnormalities in arrangements. However, with the advent of FISH and CGH, it has become possible to detect both numerical and structural cytogenetic changes.

Mining trucks are defined as specialized trucks used for carrying and hauling mining materials such as minerals, metals, and coal. The global truck mining market is segmented into light-duty vehicles, medium-duty vehicles, and heavy-duty vehicles. When the gross weight of the vehicle is more than 33,069 lbs., it is termed as a heavyduty vehicle. Heavy-duty vehicles, such as mining trucks, are designed in several different processes such as follows

Metals used in automotive, aerospace and defense, and other industries are required to have certain physical and chemical properties based on their use. Metal heat treatment is a process that is used for changing the physical and chemical properties of metal to attain the desired engineered requirements. The process involves heating of metals in a furnace to change their metallurgical properties. Furnaces heat the metals up to 2,000-2,700°C following which the metals are subjected to different processes such as annealing, hardening, brazing, quenching, and carburizing. In the metal heat treatment process, the absence of air as well as other gases in the furnace averts heat transfer through convection, resulting in zero possibility of contamination.

Legal practice management software helps to manage legal case and client records, time tracking and billing, document management, centralized case management, and calendar and case schedules. The software also handles all front and back office needs including general ledger, time recording, billing, and accounting. It is mainly used by law firms, in-house legal professionals, corporate, and government departments. The implementation of software allows end-users to maintain a leadership position by controlling every aspect of financial practice management while managing stringent compliance protocols.

The global transportation industry is progressively adopting decarbonisation strategies. These have been relatively accomplished in transportation companies through the adoption of land-based transportation but are yet to establish in the shipping industry. This is due to the fact that the global maritime industry is heavily dependent on fossil fuels. Additionally, oil prices have also encountered an all-time low, which further acts as a deterrent factor for shipping companies to shift toward a more carbon-free economy.
