An optical sensing system detects pressure through attenuation of light in an optical fiber. This is particularly useful for measuring the weight and position of a load on a mat including multiple such optical fibers, which may be positioned in an automobile seat to determine theses parameters for a passenger in that seat. This information can be presented to an airbag deployment system in a form that will easily enable the airbag to be deployed (when needed) in a manner sensitive to the weight and position of the occupant. It provides based on this detection system a technique to suppress airbag deployment based on passenger profile. Further, the system and method use an optical fabric methodology such that loads, load movement, load position can 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.
