An optical sensing system detects pressure through attenuation of light in an optical fiber. The weight and position of a load on a mat including multiple optical fibers may be determined; for example, such a mat may be used in an automobile seat to determine theses parameters for a passenger in the seat. This information can be presented to an airbag deployment system to easily enable the airbag to be deployed or suppressed in a manner sensitive to the weight and position of the occupant. This methodology allows loads, load movement, and load position to be detected in vehicles. In applications for vehicles such as aircraft or boats, sensing weight, position and movement of cargo can warn an operator or pilot in sufficient time to correct dangerous shifts in weight within the cargo portion of the vehicle or to modify the operation of the vehicle to compensate for such shifts. |
