  The imaging instruments on board INTEGRAL have wide fields of view and high
time resolution. Therefore, they are ideal instruments to search for pulsating
sources and/or transient events. We are systematically searching for pulsations
and transient events from known and serendipitous sources in the Galactic Plane
Scan (GPS) and Galactic Center Deep Exposure (GCDE) core program data. We
analyze the standard pipe-line data using
  ISDC Off-line Science Analysis (OSA) system, so that our results are
reproducible by general guest users. In this paper, we describe our system and
report preliminary results for the first year of operation.
