A commercial boiler is a pressurized system that creates heat by burning combustible fuel to provide heating for residential and commercial buildings. Burner, combustion chamber, heat exchanger, controls, and exhaust stacks are just a few of the components that make up a commercial boiler. These add-ons are essential for a commercial boiler's optimal operation. However, due to efficient operation of commercial boilers, regional governments have mandated the installation of safety accessories in commercial boilers under the Code of Federal Regulations (CFR) and the India Boiler Regulation (IBR).

Though not officially recognised by SAE under SAE levels of autonomous driving, L2+ is a new level of autonomy, adopted by the automotive industry, which bridges the capability and requirements gap between Level 2 and Level 3 automated driving. Over the next few years, L2+ is expected to enjoy a larger market share than L2 and L3 have. The higher adoption of L2+ will provide a larger number of consumers, with access to and acceptance of automated driving systems.
