What companies would be greatly affected if the value of a dollar goes down?

I know that some Companies like Nike are dependent on cheap labor. Are there any other companies that would be affected? Thanks, I am writing a research paper for college class. I needed some more concrete examples.

Any company that manufactures here and ships overseas would benefit. You can say all companies that manufacture overseas and ships here would lose but you need to take into account that some countries manage their Currencies to keep the dollar higher. China is one such country.
