Military fitness equipment constitutes machines for workout and devices that help in monitoring soldiers' physical exercises. It helps in improving the stamina, developing muscular strength, and joint flexibility of military personnel and maintaining mental strength and agility.

Machine tools play a dominant role in the manufacturing industry and are part of almost every metal processing application. They are used for cutting and shaping metals and other materials to the specification provided by the product manufacturers. The machine tools help to process and manufacture critical components with utmost accuracy and ease. Based on the criticality of the operation, conventional or computer numerical control (CNC) machine tools are used.

A sensor is a device that measures or responds to physical changes in the environment and converts the signals appropriately. Sensors that use magnetic fields to sense changes in the environment are known as magnetic field sensors. The applications for magnetic sensors mainly include speed sensing, motion sensing, and direction sensing. These sensors have found application in different sectors such as the automotive, wireless and consumer electronics, industrial, military, energy, medical, and data processing. Non-optical sensors essentially measure forms of mechanical stress over the subjects and do not use light as a medium.

An OLED emits light in response to an electric current. In an OLED, the emissive electroluminescent layer is a film of organic compound, which is responsible for the emission of light on application of electricity. OLEDs are used to create digital displays in various electronic applications such as TV screens, PC monitors, mobile phones, and gaming consoles. An OLED can display deep black levels on screens and is lighter and thinner when compared to a light-emitting diode (LED). An OLED achieves a higher contrast ratio than an LED in low ambient light conditions such as a dark room. The following exhibit represents the history and evolution of OLED.

An optocoupler is essentially a passive optical component that can split or combine optical power transmission data from optical fibers. Furthermore, the optocoupler is designed to transfer electrical signals through light waves to enable coupling with electrical isolation between input and output. An optocoupler primarily prevents the fluctuation in voltages, from damaging or distorting transmission components on both sides of the circuit. An optocoupler has a light source, mostly near a LED that converts the electrical input signal into light, a photosensor, and a closed optical channel that detects incoming light and regulates electric current flowing from an external power supply. The sensor can either be a silicon-controlled rectifier, a photoresistor, a phototransistor, a photodiode, or a triac.

With the developments in the orthopedic market, there has been an emergence of product offerings, which facilitate robotic and computer-assisted surgeries. Such products are gaining traction due to the increase in the demand for musculoskeletal disorders across all the age groups, and the increased demand for procedures that enhance precision and eliminate any revisions. As opposed to open surgeries, the forecast period is expected to see a burgeoning demand for minimally invasive surgeries (MIS), which improve functional outcomes and reduce recovery times and hospital stays for patients.

The past century saw the dominance of fossil fuels as the chief source of energy for the sustenance of the global economic machinery. Among these fuels, crude oil has controlled almost all the aspects of the energy business. It is defined as a mixture of compounds composed primarily of carbon and hydrogen in varying proportions with the presence of inorganic compounds such as nitrogen, sulfur, and metals like vanadium and mercury. Crude oil is found in specific rock formations, called reservoirs, deep in the earth's crust. The depth at which these reservoirs occur can vary significantly from pools, which flow up to the surface to almost 15,000 meters underground. The method employed to get to these reservoirs of black gold is through drilling the surface until it reaches the pre-defined depth.

CT uses a combination of computer-processed multiple X-ray images taken from different angles to generate cross-sectional images that can be reformatted in multiple panes and can even produce 3D images. This technique provides high-quality images of the internal organs of the human body as compared with the traditional X-ray technique. CT scanning can facilitate the diagnosis of cardiovascular diseases, infectious diseases, trauma and musculoskeletal disorders, appendicitis, and complex medical conditions such as cancer.

Medical imaging is the process of creating visual representations of the interior of a body for clinical analysis and medical intervention. Medical imaging is performed to reveal internal structures hidden by the skin and bones, to examine and diagnose the medical condition. It plays a vital role, not only in the diagnosis but also in the treatment process, since it is taken into consideration during the follow-up of various diseases. Various methods for medical imaging include X-rays, ultrasonography (ultrasound imaging), CT, and MRI. For the diagnosis and treatment of various disease, these methods are used individually or in combination for a better understanding of the medical condition.

PPE is used to protect workers from hazards in various industries such as construction, mining, manufacturing, and oil and gas. With growing industrial production globally, PPE is employed in almost all industries. This report provides insights into PPE used for aerospace and aviation industry. The global growth in the industry calls for increased protection for the workforce in various operations.
