Abstract: Provided are a substrate support unit and a substrate treating apparatus and method using the same. The substrate support unit includes a first support part and a second support part. The first support part is movable in a first direction. The first support part supports a first portion of a substrate in which a processing fluid is supplied in a direction corresponding to the first direction. The second support part is movable in a second direction. The second support part supports a second portion of the substrate. At least one of the first support part and the second support part supports the substrate while the processing fluid is supplied.

Abstract: A system and method are provided for vehicle passenger classification. The system may include a plurality of weight sensors installed under a seat frame to support a load of a vehicle seat, a single dummy sensor installed under the seat frame to support the load of the vehicle seat along with the plurality of weight sensors, and a passenger classification logic unit for classifying a passenger value obtained by summing sensor values of the plurality of weight sensors as either class 1 or class 2 by comparing the passenger value with a first reference and a second reference.
