Abstract: An occupant weight-based airbag suppression method utilizes adjustable time constant filtering and dynamic threshold adjustment to reliably determine and indicate airbag suppression status. The filter time constant is ordinarily set to a first value that provides relatively fast tracking of the raw occupant weight, but is set to a second value that provides relatively slow tracking of the raw occupant weight when both the raw and filtered occupant weights are within a specified band about the threshold value. The threshold value and band are dynamically adjusted after the suppression status is initially determined so as to effectively increase the separation between the filtered weight and the threshold.

Abstract: A system for testing an integrated circuit device under test (DUT) communicating though synchronous digital signals and through a high speed serialization/de-serialization (serdes) bus includes a serdes interface circuit for communicating with the DUT via the serdes bus and an integrated circuit (IC) tester for communicating with the DUT and with the serdes interface circuit via digital signals. State changes in the digital signals are synchronized to a clock signal within the IC tester. The serdes interface circuit receives instructions from the IC tester via at least one of the digital signals and responds to the instructions by transmitting data to the DUT via the serdes bus using appropriate serdes protocol, by receiving and storing data transmitted by the DUT via the serdes bus, and by thereafter forwarding the stored data to the IC tester via at least one of the digital signals.
