QUES: Machine vision systems often require bright and homogeneous illumination, so features of interest are easier to process. LEDs are often used for this purpose, and this is likely to remain one of their major uses until the price drops low enough to make signaling and illumination uses more widespread. Barcode scanners are the most common example of machine vision, and many low cost products use red LEDs instead of lasers. Optical computer mice are an example of LEDs in machine vision, as it is used to provide an even light source on the surface for the miniature camera within the mouse.

QUES: Chinese political philosophy dates back to the Spring and Autumn Period, specifically with Confucius in the 6th century BC. Chinese political philosophy was developed as a response to the social and political breakdown of the country characteristic of the Spring and Autumn Period and the Warring States period. The major philosophies during the period, Confucianism, Legalism, Mohism, Agrarianism and Taoism, each had a political aspect to their philosophical schools. Philosophers such as Confucius, Mencius, and Mozi, focused on political unity and political stability as the basis of their political philosophies. Confucianism advocated a hierarchical, meritocratic government based on empathy, loyalty, and interpersonal relationships. Legalism advocated a highly authoritarian government based on draconian punishments and laws. Mohism advocated a communal, decentralized government centered on frugality and ascetism.
