Smart helmets are an efficient safety tool that improves situational awareness and traffic safety. Smart helmets are becoming increasingly popular among consumers, primarily because of features such as integrated communication systems, real-time navigation, and increased safety. The helmet is developed as a smart for detecting accidents in motorcycles and also sends the geographical location to the concerned authorities. The device is interconnected with IoT, which is embedded with sensors, software, and network connectivity. The smart helmet has dual-mode Bluetooth technology, an integrated video camera, turn signal indicators and brake functions, speakers, and microphones to connect with mobile phones.

A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by an overcurrent or short circuit. Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire.

A bioreactor is a manufactured or engineered device or system that supports a biologically active environment, which could include the growth of cells and tissues in a cell culture process.

Syringes and needles are the sterile medical devices that are used to inject fluids/solutions or to withdraw secretions from the body. Needles are one of the commonly used medical devices in the healthcare system.

A smart sensor has a multi-sensing capability that is widely used to measure the temperature, pressure, humidity, and position and processes the collected data using microprocessors and advanced computation models. Smart sensors enable accurate as well as automated collection of data.

Smart musical instruments are traditional musical instruments enhanced with digital technology to provide additional features, capabilities, and connectivity options. These innovations are designed to improve the playing experience, offer new creative possibilities, and integrate with modern music production and performance environments.

Scuba diving comprises diving activities that are carried out using a Self-Contained Underwater Breathing Apparatus or SCUBA, which is completely independent of surface supply. Scuba diving equipment refers to the specialized gear and tools used by divers to explore the world underwater. This equipment typically includes a diving mask, a snorkel, fins, a buoyancy control device, a regulator, a dive computer, a wet or dry suit, underwater cameras, and other equipment. These essential diving tools ensure the safety, comfort, and enjoyment of divers while underwater.

The small wind turbines refers to the upwind machines which converts wind energy into electrical energy with the help of blades, rotors, and generators. They offer a lot of alternative power for electrical devices. Small wind turbines have traditionally been utilized in cottages, marine farms, and other rural applications where there is limited access to electrical grids.

An automotive camless engine is defined as an engine configuration wherein the poppet valves are operated using pneumatic, electrohydraulic, or electromagnetic actuator systems instead of conventional cams. The intake or exhaust valves are operated using this camless arrangement of the camshaft, which incorporates the use of springs or other means. This type of engine configuration has been recently developed by engine designers and developers for achieving optimum performance and fuel efficiency in addition to reduced carbon emissions.

A heating and cooling system known as an air source heat pump pulls heat from the outside air and transfers it inside a building for space heating or cooling. It functions as an energy-efficient substitute for conventional heating, ventilation, and air conditioning (HVAC) systems by compressing refrigerant gas to absorb and release heat. Owing to their adaptability and suitability for use in commercial, industrial, and residential settings, air source heat pumps help save energy and have a smaller negative environmental impact.
