A document scanner is a device that scans a paper document and converts it into a digital format, which can be stored on digital devices. The process of document scanning is also referred to as document imaging.

Dosimetry equipment refers to devices and instruments used to measure, monitor, and assess exposure to ionizing radiation in various environments. These tools ensure radiation safety by accurately detecting and quantifying radiation doses received by individuals or objects. Common types include thermoluminescent dosimeter (TLD), optically stimulated luminescent (OSL) dosimeters, electronic dosimeters, and ion chambers. Widely used in healthcare, nuclear energy, industrial applications, defense, and research, dosimetry equipment helps maintain regulatory compliance with radiation safety standards and protect personnel from harmful radiation exposure.

The global education personal computer (PC) and tablet market is the part of the technology industry that focuses on providing personal computers (PCs) and tablets specifically designed for use in educational settings, such as schools, colleges, universities, and other learning environments. These devices are tailored to meet the unique requirements of educational institutions and students, including durability, compatibility with educational software, ease of use, and affordability.

As defined by the National Institute of Health, precision medicine is a medical approach that designs the customization of healthcare for disease treatment and prevention by considering changes in the genes, environment, and lifestyles of individuals. Precision medicine is the latest development in the healthcare sector. This approach helps researchers and doctors in identifying accurate and preventive treatments for diseases. The implementation of AI is advancing the development of precision medicine. Technology companies and medical organizations are using AI to develop precision medicine in multiple ways.

Dried food refers to food products that have undergone a drying or dehydration process to remove the majority of their water content. This preservation method helps extend the shelf life of the food by inhibiting the growth of bacteria, yeasts, and molds that cause spoilage. Drying food reduces the moisture content, making it less prone to deterioration and allowing for long-term storage without the need for refrigeration. Dried food can be produced from various sources, including fruits, vegetables, meat, seafood, herbs, spices, nuts, grains, and more. The drying process typically involves exposing the food to controlled heat, air circulation, or sunlight, which helps evaporate the water while retaining the flavor, nutrients, and texture to a certain extent.

A drone data link system allows communication and enables the transfer of data between a drone and the ground station. The complexity of the technology used is dependent on the type of drone in operation and its mission characteristics.

Drones are pilotless aircraft or flying robots, which are also referred to as UAVs. Drones fly autonomously or are controlled by an onboard computer. They can also be operated using a remote control from the ground. Commercial drones are drones that are used in commercial sectors such as industrial, terrestrial imagery and mapping precision agriculture, inspection and monitoring, and others.

A dropper is a device that is used to dispense small quantities of liquids in the form of drops. A standard dropper includes a pipette, a cap, and a bulb.

The "duty-free and travel retail for airlines market" encompasses the retail sector dedicated to selling goods to passengers, often at prices free from specific local taxes and duties. Primarily aimed at international travelers, duty-free shopping is predominantly accessible to those flying internationally. However, there are instances where domestic travelers can also avail themselves of these services.

An e-bike, also known as a booster bicycle, consists of an integrated electric motor for propulsion. Based on the power that the electric motor can deliver and control the system, e-bikes can be classified as e-bikes with pedal assist only, those with power-on-demand and pedal assist, and those with power-on-demand only. An e￾bike battery is used to power e-bikes and is basically a rechargeable battery, which can be recharged at any charging station or at home.
