This invention provides a filter system which may be implemented with less hardware and software resources than traditional filters. In one implementation, a method is provided that includes receiving an impression request for which an advertising impression is desired, screening HTML content of a web page identified by the impression request, generating a rating based on the HTML content of the web page, and assigning the rating to the impression request. The enabling of automatic transaction retries is accomplished either at deployment time by setting properties in the deployment descriptor of an instance of a class, such as EJB, or at runtime by setting properties on the EJB via a console on the application server. In the region of the roof side member, ahead airbag, which, when triggered in the region of the C pillar, impinges on the C pillar covering assigned to the C pillar, opens the C pillar covering along a desired opening line formed by a material recess. Also described are various designs for DUT’s to obtained enhanced accuracy of the delay timing.
