Abstract
An arrangement (14) is used in a vehicle (10), and contains an occupant characteristic sensor (36), a filter (62) and a controller (24). The sensor (36) senses an occupant characteristic and outputs a signal indicative thereof. The filter (62) and the controller (24) operate to monitor the signal for a frequency component indicative of a vehicle crash event. In one example, the arrangement (14) is part of an occupant protection system (12) that includes an actuatable protection device (16). The controller (24) controlling actuation of the protection device (16) in response to the filtered frequency component.
