The automotive wiper blade system forms a fundamental part of any kind of automobile. Although the system comes as a standard fitment with every vehicle, it was invented many years after the invention of automobiles. An American woman named Mary Anderson from Alabama is believed to have invented the equipment. The idea struck her while she was travelling to New York city, US, during winters in a trolley car and noticed that the driver had limited visibility due to frost formation on the windshield.

An automotive cylinder head is the end cover in an internal combustion engine. It is used against the piston, which compresses the cylinder's contents. In an internal combustion engine, the cylinder head sits above the cylinders on top of the cylinder block. It closes the top of the cylinder, which forms the combustion chamber. This joint is sealed by a head gasket. In most engines, the head also allows air and fuel to be fed into and out of the cylinder. The head can also be used to mount valves, spark plugs, and fuel injectors. A cylinder head needs to be robust to withstand high pressure and temperature, while retaining its shape and form to seal the cylinder block through the head gasket.

The braking system forms a fundamental part of the vehicle along with the engine, powertrain, and vehicle body. Started as a mechanical device in the vehicle, the system aids in slowing or stopping the vehicle by means of friction. Since the invention of commercially viable automobiles in the late 1920s, technological advances have evolved the vehicle into a much safer, comfortable, and eco-friendly experience. Vehicles have now become more than just a means of transportation. Innovations and developments have made vehicles more powerful and intelligent with the rapid adoption of electronics that can self-learn to adapt with real-time driving situations. Automobiles of toady boast of more electronics than mechanical parts and components with an average hatchback consisting of over 35%-40% electronic components in 2015 and we expect this to rise to over 60% by 2020. With rapid acceleration in technological development, the automotive braking industry is experiencing a gradual shift from mechanical to hydraulic braking, which is now rapidly shifting to electronically-controlled braking systems.

Anterior cervical fixation is performed surgically to treat damaged/herniated discs that cause compression of spinal cord or nerve root. The surgery stabilizes the corresponding vertebrae, and the pain is decompressed by fixing the anterior fixation system with essential anterior plating, screws, and implants.

Data converters are used to convert and condition signals from analog to digital and vice versa. They are integrated into the device to convert digital signals to analog signals and vice versa. The use of data converters in the devices enhances the processing, data transmission, and process control capabilities. These data converters are based on the architectures that are proprietary architectures of companies such as Analog Devices and Texas Instruments or are patented. The core of these data converters is either based on complementary metal-oxide semiconductor (CMOS) or silicon or silicon on germanium materials forming the essential gateways for signal conversion and conditioning. There are two types of data conversions:

3D displays exhibit images with depth perception by using various technologies such as multi-view, stereoscopic, and 2D-plus-depth displays. However, to experience depth perception, special 3D glasses are required to view the images from 3D displays. Some display technologies that do not need special glasses include an active shutter 3D system and a polarized 3D system (or autostereoscopic system). 3D displays are used in various devices such as 3D TVs, mobile handsets, tablets, gaming devices, and HMDs.

The global bone-anchored hearing aids market is a niche segment of the global hearing aids market and accounted for a market share of 2.47% in 2015. The global bone-anchored hearing aids market is expected to see a stronger substantial growth compared with other hearing aids in the market. The factors such as sound quality, less expensive than its alternative (cochlear implant), low maintenance cost, better comfort, and reduced ear infection will encourage customers to opt bone-anchored hearing aids over other hearing aids available in the market.

The evolution of smart homes resulted in the installation of integrated and centralized control systems in homes that include: Environmental control systems (air conditioning, heating, and ventilation) Household appliances (washing machines, refrigerators, freezers, and microwaves) Consumer electronics (TV, gaming consoles, and audio-video equipment) Building components (windows and doors) In a connected home, these systems are connected to a computer, tablet, or a smartphone through a wired or a wireless network to enhance remote accessibility. Ubiquitous homes understand the requirements of occupants based on their lifestyle and behavior, and, hence, respond in a particular manner.

Musical instruments refer to tools or devices that are used to create musical sounds. Musical instruments are made up of materials such as wood, metal, string, and nondurable materials. Some of the most commonly used musical instruments are guitar, piano, wind instruments, keyboard, and percussion.

Freeze drying is a process that involves the removal of water or other solvents from a frozen product by a phenomenon called sublimation, which occurs when a frozen liquid undergoes a phase change directly to the gaseous phase without passing through the liquid phase. On the contrary, drying at ambient temperatures from the liquid phase generally results in changes in the product, which may suit only certain materials. However, in freeze drying, the material does not go through the liquid phase, and this allows the preparation of a stable product that is easy to use and aesthetic in appearance.
