"AF-S" tamron/sigma lense

[photo12345]

what terminology does tamron, sigma and tokina use compared to Nikons AF-S.

When looking for a lense that will auto focus on a camera body with no auto focus.

Thanks

Tamron = USD, Sigma = HSM.
This site gives lists of what various manufactures mark on their lenses and what they mean, What do all those cryptic number and letter codes in a lens name mean?
