HDC is a controlled downhill descending technology that allows the vehicle to descend a slope at a controlled speed. It works in tandem with ABS and traction control to manage the speed of each wheel independently to maximize the grip of each wheel to the terrain. In 1993, Bosch first introduced HDC to the industry when it designed an HDC system for Land Rover Freelander model. However, this feature was criticized by enthusiasts as the descent speed was considered too fast to be labeled as controlled descent.

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.

The credits of inventing a fifth-wheel coupling goes to Otto Neumann and August Fruehauf, when they first invented the semi-trailer back in 1914. A few years later, they adopted an improved version of the fifth-wheel offered by inventor Hermann Farr and his partner, Charles Martin. Martin introduced Farr's invention of the fifth wheel in 1915 when inventor Farr applied for the patent of his fifth wheel on June 4, 1915. The patent was granted in 1916, after which a partnership with Charles Martin was initiated. The company's fifth-wheel prototype was round in shape, giving the industry a nickname 'fifth-wheel.' It was equipped with hinges that made travel on unpaved or rolling roads much easier. This was a great improvement on other types of primitive hitches, which led to an increase in semi-trailer sales thereafter.

Herbal tea is made by boiling or steeping herbs, and is an infusion made from a plant other than Camellia sinensis. Flower tisanes such as chamomile, lavender, hibiscus, and rose are usually used for making herbal teas. Even leaf tisane such as mint, lemongrass, French verbena, and lemon balm can be used for making herbal teas. Other tisanes used to blend herbal tea are root tisanes, fruit tisanes, and seed or spice tisanes.

Most consumers consider cosmetics as impulse purchase goods. Despite the economic slowdown in several countries, consumers treat these products as an affordable luxury. For instance, despite the slowing economic conditions, consumers in Brazil spend on color cosmetics. Attractive packaging and the trend of growing consciousness about health and wellness are adding to the growth of the overall color cosmetics market. However, the growing availability of counterfeit products is negatively affecting the growth of the overall market. The global color cosmetics market is expected to post a CAGR of 5.19% during the forecast period.

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.

A biosensor consists of a bio-response recognition component. It can be referred to as a bio-component with a transducer that converts a biological response into an electrical signal, which is then amplified, processed, and displayed on the display unit. The combination of the bio-component and the transducer is referred to as the biosensor.
