A minor invention is a small invention that has a significant impact on everyday life. FIBS is an acronym for 'Fiber Optic Based Sensors', which are small sensors that use light to detect changes in the environment. These sensors are used in a variety of applications, such as medical diagnostics, environmental monitoring, and industrial automation. They are also used in consumer electronics, such as smartphones and tablets. Minor inventions like FIBS have revolutionized the way we interact with technology and have made our lives easier and more efficient.
