  We present two inclusive measurements of Cabibbo-Kobayashi-Maskawa (CKM)
matrix element Vub: one uses the lepton energy spectrum (E_l) and the other
uses the invariant mass of the hadronic system (m_X) to discriminate signal (B
-> X_u lnu) and background (B -> X_c lnu) events in B -> Xlnu transitions. Both
analyses are based on data samples collected by the BaBar detector at the
PEP-II asymmetric-energy B Factory at SLAC.
