A mirrorless camera is a type of digital camera that does not require a reflex mirror to reflect images. Mirrorless cameras, therefore, do not have mirrors and optical viewfinders; instead, they use electronic viewfinders (EVF). These cameras are available with fixed lenses and interchangeable lens features. A mirrorless camera is generally smaller than a digital single-lens reflex (DSLR) camera. Mirrorless cameras are known in industry terms, such as compact system cameras (CSC), hybrid cameras, mirrorless interchangeable-lens cameras (MILC), and non-reflex cameras.

Military drones refer to unmanned aerial vehicles (UAVs) that are specifically used for military purposes such as border surveillance, battle damage management, combat operations, communication, delivery, and anti￾terrorism weaponry.

A metal sawing machine is a device for cutting up bars of metal or for cutting out shapes in plates of raw materials (metals). The cutting tools in sawing machines may be thin metallic disks with teeth on the edges, thin metal blades, or flexible bands with teeth on one edge, or thin grinding wheels.

Medical device testing refers to the process of evaluating and verifying the safety, functionality, and performance of medical devices to ensure they meet regulatory standards and industry requirements. This involves various tests, such as biocompatibility testing, electrical safety testing, software validation, and sterilization validation, to confirm that the device is safe for use, performs as intended, and complies with local and international regulations before it reaches the market.

Mechanical connectors encompass the manufacturing, distribution, and sale of various types of connectors used for mechanical connections in different applications. Mechanical connectors are devices or components designed to join or connect two or more mechanical parts together, providing a secure and reliable connection.

Linear actuators are used to convert energy (power from air, electricity, or liquid) into linear motion. These actuators convert rotary motion into linear motion by means of a linear motor, a belt, or a screw drive. The linear actuators that convert energy from air into linear motion are called pneumatic linear actuators; the linear actuators that convert energy from the fluid into linear motion are called hydraulic linear actuators, and the linear actuators that convert energy from electricity to linear motion are referred to as electric linear actuators.

LED lighting is based on fixed light source installations, which deliver a practical or aesthetic lighting effect. The general lighting industry is moving toward energy-efficient lighting, leading to technological innovations in the market. LED lighting solutions provide advantages such as low voltage and current requirements, high reliability, low radiated heat, negligible emission of ultraviolet (UV) rays, and a longer lifespan than conventional lighting sources. As a result, the adoption and penetration of LEDs in the general lighting industry are rising.

Leather tanning machinery refers to a type of industrial equipment that is used in the tanning of animal hides and skins into leather. The importance of leather tanning machinery depends on its ability to effectively and efficiently convert raw animal hides into usable leather products.

Laser printers use the principle of electrophotography or electrostatic charges for printing. Laser light is used for inducing charges to facilitate printing. The laser light induces charges on the printer drum, which is opposite to the charge of toner inks in the printer. With opposite charge polarities, where the drum is positively charged, and the toner is negatively charged, the ink in the toner gets attracted to the drum. The ink stuck on the drum is in accordance with the image or data provided to the printer. The negatively charged toner ink, which sticks in the format of the image as provided, gets attracted to the positively charged paper. This creates a replica of the original image provided to the printer.
