Capitalization of Technical Terms/Proper Nouns
All of your examples should be spelled out in lowercase because they do not describe unique, one-of-a-kind elements, rather they describe a type or class of element. One way to verify is to ask if you can use an article in front of them, such a "a" or "the" or if you can make them plural; if so, then they are not proper nouns and should not be capitalized. For example, you could say the electronic stability control on my Ford works much better than the electronic stability control on my Toyota.
