Improvements to Devices Made by Black Americans

In addition to inventing many devices and methods of doing things that affect everyday life, Black Americas have also been at the forefront of improving inventions that were already patented. Some of these devices include the light bulb, the airplane, the cotton gin, the player piano, several new- generation computers, high-capacity computer chips, devices used in cell communication systems, laser digital readout devices, and many types of tools used to develop other machines. Once these machines were developed, many safety devices have been developed to ensure the safety and easy use of patented inventions. Although the list below does not even come close to being a complete listing of Black American innovative ideas, it does highlight some of the inventions that are used in everyday life.
