The impact parameter trigger of CDF has been extensively used to measure properties of B mesons at low momentum transverse to the beam. The same device can be used to produce b-enriched samples at high transverse momentum to lower thresholds or improve the statistics of measurements involving production of b jets. The first measurements based on these samples, for b-jet pairs and b production in association with photons will be presented, as well as the use of b-enriched datasets for new physics searches.
