  • Patent number: 8091414
    Abstract: Methods of monitoring replacement of a diesel particulate filter (DPF) by a non-particulate matter filter. The disclosed methods takes into account a change in delta pressure based soot load estimates (DPSLE) over time to detect whether the DPF has been replaced. The estimate, which is measured by the delta pressure drop across the filter, can be used to determine whether a device that does not have the capability of trapping soot, such as a muffler, has been inserted.

  • Patent number: 7245024
    Abstract: An electronic assembly includes a substrate and at least one surface mounted electronic component. The substrate includes a first side and a second side opposite the first side. The first side of the substrate includes a plurality of conductive traces formed thereon. The plurality of conductive traces includes a first conductive trace and a second conductive trace. The electronic component is electrically coupled between the first and second conductive traces. A component body of the electronic component is subject to interaction with a flux, which is utilized during electrical coupling of the electronic component to the first and second conductive traces, to form a current leakage path. The substrate is configured to prevent the formation of the current leakage path.
