| 20080234899 | Vehicular Occupant Sensing and Component Control Techniques - Method and system for obtaining information about a category of an occupying item in a volume of a passenger compartment of a vehicle in which the occupying item is situated during use of the vehicle and controlling one or more vehicular components. A time-varying signal is directed into the volume from at least one location. A modification of the directed signal arising from a property of any occupying items in the volume is detected, different occupying items causing different modifications of the same directed signal. A distinction is made between different occupying items of the volume or between parts of an occupying item based on the detected modification to the directed signal and each component, e.g., an inflatable airbag, is controlled based on the distinction between the occupying items or parts thereof. | 09-25-2008 |
