A non-mydriatic handheld fundus camera is a portable diagnostic device used to capture high-resolution images of the retina without the need for pupil dilation (mydriasis). It is commonly used by ophthalmologists and healthcare professionals for non-invasive retinal screenings, allowing for the early detection of eye diseases such as diabetic retinopathy, glaucoma, and age-related macular degeneration. The compact design of the camera makes it ideal for use in various healthcare settings, including hospitals, clinics, and ambulatory surgical centers.

A network interface card (NIC) is a hardware component that allows a computer to connect to a network. It is a circuit board installed in a computer that provides the computer with a dedicated network connection. It is sometimes referred to as a network interface controller, a network adapter, or a LAN adapter

A music synthesizer is an electronic musical instrument that generates audio signals to imitate traditional musical instruments such as piano, flute, vocals, and others. The electric signals in a synthesizer or synths are converted into sound with the help of amplifiers and speakers. These instruments are mostly played in conjunction with a keyboard. A synthesizer can also be controlled using musical instruments, such as guitars, sequencers, drums, and fingerboards.

A multi-functional printer (MFP) is a system that comprises the functionality of a printer, scanner, fax, and copier in a single system. Some MFPs do not have fax functionality, which is not considered a norm for MFPs, as it is no longer a popular mode of document exchange.

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.

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.

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.

K-12 blended e-learning is an educational approach that combines traditional face-to-face classroom instruction with online learning components. This model enhances the learning experience by leveraging the flexibility and accessibility of digital tools while maintaining the benefits of in-person teaching

Intelligent pumps refer to pumping equipment that can regulate and control flow or pressure. These are also defined as a combination of pumps that have a variable frequency drive and digital control capabilities. They help in managing energy consumption in end-user industries by remotely monitoring the processes and ensuring control of remote systems. Intelligent pumps include wireless control and monitoring capabilities that enable end-users to access real-time operational data. This helps reduce downtime in processes and improves the predictive maintenance plans of end-users.
