A nitrogen oxygen sensor or NOx sensor is typically a high-temperature device built to detect nitrogen oxides in combustion environments such as an automobile, truck tailpipe or smokestack. The drive to develop a NOx sensor arises from environmental factors. NOx gases can cause various problems such as smog and acid rain. Many governments around the world have passed laws to limit their emissions (along with other combustion gases such as SOx (oxides of sulfur), CO (carbon monoxide) and CO2 (carbon dioxide) and hydrocarbons).

Thunderbolt cables. Released from mid-2016, copper versions of Thunderbolt 3 cables were released at lengths up to 2 m (6.6 ft). However, shorter lengths up to 0.8 m (3 ft) (initially only available at up to 0.5 m (1.6 ft)) are passive cables offering the full 40 Gbit/s speed. 2 m (6.6 ft) cables are available in two types: passive ones offering only 20Gbit/s speed but cheaper in cost, and more expensive active 2 m (6.6 ft) ones offering the full 40 Gbit/s speed.

Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems. It is primarily performed by highly skilled and specialty trained gastroenterologists.

Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man-made structures. Scaffolds are widely used on site to get access to heights and areas that would be otherwise hard to get to. Unsafe scaffolding has the potential to result in death or serious injury.

Types of flexible dredge hose include the floating rubber hose, discharge hose, suction hose, armored hose and ceramic hose. To achieve a better pressure resistance, hoses can be reinforced with fibers or a steel cord. Commonly used reinforcement methods are braiding, spiraling, knitting and wrapping of fabric plies. The reinforcement increases the pressure resistance but also the stiffness.
