Abstract: A distributed sensing system and method improves sensing of events that may require restraint deployment in a vehicle by distinguishing between deployment events and non-deployment events using data from more than one sensor. A transmission check process continuously monitors an incoming signal from a sensor and counts the number of data samples that exceed a selected value using a counter.
