A sonobuoy is a small, expendable sonar system used primarily by naval forces to detect underwater objects such as submarines. Deployed from aircraft or ships, it floats on the ocean surface while its sensors descend underwater to transmit acoustic data back to operators via radio signals. Sonobuoys are essential tools in anti-submarine warfare (ASW), enabling real-time tracking and surveillance of underwater threats. They come in various types, including passive (listening only) and active (sending and receiving sound pulses), and are designed for short-term use in tactical operations.

Social robots are autonomous robots designed to interact and communicate with humans in a socially acceptable manner. They are equipped with advanced sensors, artificial intelligence, and communication capabilities to understand and respond to human emotions, speech, and actions. These robots are often used in various settings, such as healthcare, education, customer service, and companionship, to assist, entertain, and engage with people.

Smart plugs transform ordinary appliances into smart appliances. They are cost-effective alternatives for smart appliances. Technology is expected to have a high penetration among Millennials. The use of and dependence on devices that can be controlled remotely through a wireless connection is increasing globally, which is a key factor that is driving the growth of the global smart plug market. The need for connectivity is increasing, especially because it allows consumers to control different types of devices and perform tasks remotely. Smart appliances depend on wireless technologies like ZigBee, Wi-Fi, Z-Wave, Bluetooth, and NFC, as well as the Internet of Things (IoT) and operating systems (OS) like iOS, Android, Azure, and Tizen for command and control by end-users.

A smart home camera is a stand-alone camera that connects to the Internet and can record and simultaneously stream video through the Internet Protocol (IP) network that can be accessed remotely by using smart gadgets such as smartphones and tablets, and PCs (Desktops) and Laptops. The video can be saved to a memory card (if any) installed in the camera device and other digital devices (PCs, laptops, smartphones, and tablets).

Smart home appliances are devices that are equipped with advanced technologies to connect to a network, often through Wi-Fi or Bluetooth, allowing remote control, automation, and enhanced functionality. These appliances often integrate with platforms like smartphones, tablets, or voice assistants to perform tasks efficiently and provide convenience, energy savings, or improved security.

Smart doorbells are defined as Internet-connected doorbells that notify homeowners when a guest arrives at the door. Users can view the person at the door from a smartphone or tablet. The smart doorbell is activated when the guest presses the doorbell. The user is informed of the presence of the guest through in-built motion sensors. Users can receive constant alerts about actionable security risks or other key events. Smart doorbells support the feature of two-way audio communication with visitors via wireless communication technologies such as Bluetooth, Wi-Fi, and Zigbee networks.

Semiconductor equipment refers to the machinery and tools used in the production of semiconductor devices. This equipment is essential for various stages of semiconductor manufacturing, including wafer fabrication, assembly, and testing.

Wearables technologies refer to electronic technologies that are embedded in wearables, such as smart bands, smartwatches, smart clothing, and smart rings. Wearable electronic devices are equipped with miniaturized electronic devices such as microchips and sensors, enabling them to perform computing tasks. The electronic devices embedded in wearables collect data and track activities, allowing the wearers to access information in real-time. The scope of the report includes smart bands, smartwatches, smart rings, wireless headphones, smart glasses, smart clothing, and head-mounted displays (HMDs).

X-ray equipment refers to medical imaging devices that use controlled ionizing radiation to create images of internal body structures, aiding in diagnosis, monitoring, and treatment. These systems include stationary, portable, digital, and analog machines for clinical and diagnostic applications.

Refurbished medical imaging equipment refers to devices that have been repaired, refined, and restored to their original condition without altering the product specifications. This process includes replacing worn or damaged parts with original components, updating software to the latest version, cosmetic enhancements like cleaning and painting, functional checks and repairs, calibration for optimal performance, and testing against original or revised release criteria. The critical difference between refurbished and used equipment lies in the systematic restoration of refurbished devices to meet the original equipment manufacturer (OEM) specifications and safety standards.
