Abstract: In one aspect of the present invention, a filter is provided including a first layer of sheet material having a first base portion, and a plurality of first raised portions extending from the first base portion and defining a corresponding plurality of first openings through the first layer. A second layer of sheet material also has a second base portion and a plurality of second raised portions extending from the second base portion and defining a corresponding plurality of second openings through the sheet material. The second layer of sheet material is positioned adjacent the first layer of sheet material such that the first raised portions extend from the first base portion toward the second layer, and the second raised portions extend from the second base portion toward the first layer. A gas generating system and a vehicle occupant protection system utilizing the filter are also described.

Abstract: A seat weight measuring device reduces the temperature difference generated between the resistances of measuring gauges, even when a sudden ambient temperature change occurs. Heat due to ambient temperature is transferred through a column. As a washer interposed between a sensor plate and a nut and a washer interposed between the sensor plate and the column are composed of a material having low heat conductivity and providing electrical insulation, the heat transferred through the column is prevented from being transferred to the sensor plate by the washers. Accordingly, even when the ambient temperature changes suddenly, the temperature difference between the resistances of the strain gauges is reduced. Moreover, the washers provide electrical insulation between the sensor plate and the column.
