    Abstract: A particulate filter control system and method for controlling the same is disclosed. The particulate filter load monitoring system may transmit radio frequency signals through the resonant cavity and filter medium across a frequency range sufficient to generate more than one resonant mode. The system may contain additional sensors for monitoring additional exhaust characteristics and parameters. Further, a control unit may be configured to determine the amount of material accumulated in the particulate filter, detect failures and malfunctions of the exhaust after-treatment system and its associated components, and initiate an action based on the amount of material accumulated in the particulate filter, the determination of a system failure or malfunction, or input from one or more exhaust sensors.

    Abstract: An engine having two or more fuel injectors is disclosed, where at least one of the injectors is used to port fuel inject fuel into the cylinder when the air intake valve is open. The open valve port fuel injector is used to inject a fuel that has alcohol as a constituent and is the same fuel injected by another fuel injector. In other embodiments, the open valve fuel injector is used to inject an anti-knock fuel containing alcohol while a primary fuel, is introduced by another injector. The operation of the open valve fuel injector can be optimized to maximize the vaporization cooling. In other embodiments, the open valve fuel injector may be used in conjunction with direct injection of the primary fuel or the anti-knock fuel. Heavy EGR can be optimally used with the various embodiments.

    Abstract: A system and method for determining loading of a filter having a first dielectric constant with a material having a different dielectric constant, is disclosed. The filter is contained within a metallic container forming a microwave cavity, and microwave or RF energy is created within the cavity and changes in the cavity microwave response are monitored. The changes in cavity microwave response are related to filter loading. In a preferred embodiment, the microwave energy includes multiple cavity modes thereby allowing determination of spatial distribution of the contaminant material loading. In one embodiment, the microwave cavity response includes a shift in frequency of a resonant mode. Alternatively, the microwave cavity response includes a shift in quality factor Q of a resonant mode. The microwave cavity response may include a shift in amplitude or peak width of the microwave's signal at resonance.

    Abstract: A non-radioactive source for Atmospheric Pressure Ionization is described. The electron-beam sealed tube uses a pyroelectric crystal (s). One end of the crystal is grounded while the other end has a metallic cap with sharp feature to generate an electron beam of a given energy. The rate of heating and/or cooling of the crystal is used to control the current generated from a tube. A heating and/or cooling element such as a Peltier element is useful for controlling the rate of cooling of the crystal. A thin window that is transparent to electrons but impervious to gases is needed in order to prolong the life of the tube and allow the extraction of the electrons. If needed, multiple crystals with independent heaters can be used to provide continuous operation of the device.
