  We report results of our analysis of the Kepler superaperture LC data of the
open cluster NGC6791 to search for pulsating sdB stars. We checked all pixels
and we found only three sdB stars to be pulsating, KIC2569576 (B3), KIC2438324
(B4) and KIC2437937 (B5). These stars were known to be pulsators before, though
we extended data coverage detecting more frequencies and features in their
amplitude spectra, i.e. new multiplets and more complete period spacing
sequences that we used for identifying geometry of the pulsation modes. The
multiplet splittings were also used to derive rotation periods. The remaining
known sdBs do not show any pulsation-related light variation down to our
detection thresholds. We analyzed already existing spectroscopic observations
taken with the HECTOSPEC at the MMT telescope in Smithsonian Arizona and with
the GMOS at the Gemini North telescope, and fitted atmospheric parameters using
the Balmer lines. Four stars, B3-B6, show atmospheric parameters that are
consistent with g-mode dominated sdBs. We detected hints of radial velocity
variability in B3, B5, and B6, indicating these three stars may be in binaries.
